Indlela i-WPC Construction Hoarding Enqoba Ngayo Insimbi Yendabuko kanye ne-Plywood Yezindawo Zokwakha Zasemadolobheni

Lo mhlahlandlela ubhalelwe abaphathi bephrojekthi yokwakha yasemadolobheni, izikhulu zokuphepha kwesayithi, amaqembu okuthenga ucingo lwesikhashana, kanye nabeluleki bezilinganiso zezakhiwo eziluhlaza abahlola izinketho zezinto zokwakha ezakhiweni zezindawo zokwakha zasemadolobheni ezinabantu abaningi. Sidlula ekuqhathanisweni okuhlelekile kokwakhiwa kokugcinwa kokugcinwa kokwakhiwa kwe-WPC (wood-plastic composite) ngokuqhathanisa nezindlela ezimbili zendabuko (insimbi ekhonkiwe kanye ne-plywood), okuhlanganisa isikhathi sokuphila kwenkonzo ngomjikelezo ngamunye wohlelo lokusebenza, ukuthobela imithetho yokuphepha komlilo ngokwe-EN 13501-1 kanye ne-ASTM E84, ukusebenza kwe-acoustic ngokwe-ISO 10140, ukumelana nokuguquguquka kwesimo sezulu, isikhathi somjikelezo wokufaka ngemitha eqondile, indlela yokuvuselela yokuphela kokuphila ngokwemigomo ye-LEED / BREEAM, kanye nezindleko eziphelele zobunikazi phakathi nesikhathi sephrojekthi. Umkhiqizo obhekiselwe ku-Yida Wood-Plastic yiwo Umkhiqizo we-WPC wokuqongelela izimpahla ongu-206x21, futhi uhlaka lusebenza kunoma yimuphi umsebenzi wokwakha wasemadolobheni lapho isinqumo sesikhashana sokucacisa ukuqoqwa kwempahla sihlolwa ngokwesabelomali, ukuphepha, kanye nemigomo yokuzinza yephrojekthi.

Kungani Ukukhethwa Kwezinto Zokwakha Ezigcina Izinto Kuyisinqumo Esiyisu Semisebenzi Yasemadolobheni

Ukugcinwa kwezakhiwo (okubizwa nangokuthi uthango lwendawo noma uthango lwendawo) kuyindlela yokuphepha nokuvikeleka ephoqelekile yanoma yimuphi umsebenzi wokwakha edolobheni, futhi ukukhethwa kwezinto kunomthelela omkhulu kakhulu ezindlekweni eziphelele zephrojekthi kanye nokusimama kunalokho izindleko zokuthenga zokuqala ezisikisela. Ukugcinwa kwezakhiwo kusebenzela imisebenzi eminingi ngale komngcele oyisisekelo wendawo: kunikeza umkhawulo wokuvikeleka ekufinyeleleni indawo okungagunyaziwe, ukuvimbela uthuli kanye nemfucumfucu (ngokuhambisana nemithetho yendawo), ukunciphisa umsindo emphakathini ozungezile, ithuba lokubonisa uphawu olubonakalayo kumthuthukisi kanye nomklami, kanye nokwanda kokulandisa kokusimama kwamaphrojekthi aqinisekisiwe yi-LEED / BREEAM. Izinketho ezintathu zezinto ezivelele ekwakheni edolobheni (insimbi ekhonkiwe, i-plywood, kanye ne-WPC) ngayinye iletha ibhalansi ehlukile yale misebenzi, futhi ukukhetha okuhle kuncike esikhathini sephrojekthi, izidingo zomthetho wendawo, kanye nezinhloso zokusimama zephrojekthi.

Kumaphrojekthi okwakha asemadolobheni anesikhathi sezinyanga ezingu-18 kuya kwezingu-36 kanye nokuphakama kokugcina okuzungeza umjikelezo wamamitha angu-2.4 kuya ku-3.0, izindleko zezinto zokubeka izinto ngokuvamile zimelela amaphesenti angu-0.5 kuya ku-2.0 enani lephrojekthi, kodwa umehluko wezindleko phakathi kwezinto zokwakha ungaba mkhulu kakhulu uma izindleko ezincishisiwe emijikelezweni eminingi yephrojekthi zicatshangelwa. Ukugcinwa kwensimbi okujwayelekile okune-corrugated metal kunesikhathi senkonzo esijwayelekile seminyaka emi-3 kuya kwemi-5 emijikelezweni yephrojekthi emi-4 kuya kwengu-8, ukugcinwa kwe-plywood kunesikhathi senkonzo esijwayelekile sezinyanga ezi-3 kuya kwezingu-12 ngephrojekthi ngayinye (ngokuyisisekelo ukusetshenziswa kanye kumaphrojekthi esikhathi eside), kanti ukugcinwa kwe-WPC kunesikhathi senkonzo esijwayelekile seminyaka engu-8 kuya kwengu-15 emijikelezweni eminingi yephrojekthi. Lapho izindleko zezinto zokuqala zincishisiwe emijikelezweni yephrojekthi engokoqobo, ukugcinwa kwe-WPC ngokuvamile kunezindleko eziphansi kakhulu ngomjikelezo wephrojekthi ngayinye kanye nezindleko eziphansi kakhulu zobunikazi kumaphrojekthi anokufakwa okuningi okulandelanayo.

Kumaphrojekthi okwakha amadolobha abeka phambili ukusimama, ukuphindeka kabusha kwe-WPC hoarding ekupheleni kokuphila kwayo (ngokugaya nokuhlanganisa kabusha ngomshini) kunikeza umnikelo obalulekile ekuhlukaniseni imfucuza yokwakha ku-LEED v4.1 kanye ne-BREEAM International New Construction. Iphaneli ye-WpcAma-s angachazwa futhi ngezinto ezisetshenziswe kabusha (ngokuvamile okuqukethwe okusetshenziswe kabusha okungu-30 kuya ku-50% ngemuva kwezimboni), okufaka isandla kwisikweletu sezinto zokwakha kanye nezinsizakusebenza ku-LEED kanye namakhredithi okuthola izinto anomthwalo wemfanelo ku-BREEAM. Imikhiqizo ebhekisela ku- I-Yida Wood-Plastic faka uhla lwemikhiqizo yephaneli yokuqoqa i-WPC, Umkhiqizo we-WPC cladding wakudala (esebenzisa ubuchwepheshe obufanayo bokuhlanganisa i-co-extrusion futhi ivame ukuchazwa njengesithiyo sesibili sokubona noma njengesici sokungena kwephrojekthi), kanye I-WPC decking yakudala uhla lomkhiqizo olubonisa ukusebenza kwesikhathi eside kokuzinza kombala okwenziwa yi-WPC.

Ukuqhathaniswa Kwempilo Yesevisi: I-WPC Iminyaka engu-8-15 vs i-Plywood Izinyanga ezingu-3-12 vs i-Metal Iminyaka engu-3-5

Ukuqhathaniswa kokuphila kwenkonzo kuzo zonke izinto ezintathu eziyinhloko zokuqoqa izinto zokwakha kuyisici esibaluleke kakhulu esicatshangelwayo samaphrojekthi anesikhathi esingaphezu kwezinyanga ezingu-12. Ukuqoqa izinkuni nge-plywood (ngokuvamile i-plywood yokwakha engu-12 mm kuya ku-18 mm) kunokuphila kwenkonzo okufushane kakhulu ezinyangeni ezingu-3 kuya ku-12 ngephrojekthi ngayinye ngoba i-plywood isengozini enkulu yokumuncwa umswakama, ukuwohloka kwezinto eziphilayo (ukubola, isikhunta, umonakalo wezintuthwane ezindaweni ezishisayo), kanye nomonakalo womshini womphezulu ovela emiphumeleni yendawo yokwakha. Ukuqoqa insimbi nge-corrugated (ngokuvamile ishidi lensimbi elihlanganisiwe elingu-0.5 mm kuya ku-0.8 mm) kunokuphila kwenkonzo okude eminyakeni engu-3 kuya ku-5 phakathi kwemijikelezo yephrojekthi engu-4 kuya ku-8, kodwa amaphuzu okuxhumanisa iphaneli ne-post angakhula ukugqwala ngokuhamba kwesikhathi, futhi umonakalo womthelela ovela ezimotweni zendawo yokwakha noma izinto eziwayo ungadala ukugoba okuhlala njalo okuthinta ubuqotho besakhiwo sephaneli kanye nokubukeka okubonakalayo. Ukugcinwa kwe-WPC (ngokuvamile iphaneli ye-WPC ehlanganisiwe enobukhulu obungu-18 mm kuya ku-25 mm) inokuphila kwenkonzo kweminyaka engu-8 kuya ku-15 phakathi kwemijikelezo eminingi yephrojekthi ngenxa yokumelana kwezinto ezisetshenziswayo ekumuncweni komswakama, ukuwohloka kwezinto eziphilayo, kanye nomonakalo womshini womphezulu.

I Ukuqina kwe-Wpc Inzuzo iqhutshwa izici ezine zezinto: (1) izinga lokumuncwa komswakama lingaphansi kwamaphesenti angu-1 nge-ASTM D570 uma kuqhathaniswa namaphesenti angu-8 kuya kwangu-15 e-plywood esezingeni lokwakha, okuqeda izinkinga zokuvuvukala nokuhlukanisa ezinciphisa impilo ye-plywood; (2) ukwakheka kwe-compound okuzinzile kwe-UV kumelana nokufiphala kombala kanye nokushiswa kobuso, kugcina ikhwalithi yophawu olubonakalayo kuyo yonke imijikelezo eminingi yephrojekthi; (3) ukumelana kwezinto eziphilayo kuyingxenye yokwakheka kwe-WPC (okuqukethwe kwepulasitiki okuvame ukuba ngamaphesenti angu-30 kuya kwangu-35 e-HDPE noma i-PVC kunikeza isithiyo sezinto eziphilayo), kususa izinkinga zokubola kanye nezintuthwane ezithinta i-plywood ezimakethe zezindawo ezishisayo; (4) ungqimba lwesivalo se-co-extrusion lumunca imihuzuko yobuso kanye nemiphumela emincane ngaphandle kokudalula umongo ohlanganisiwe ongaphansi, lugcina ikhwalithi yokubukeka ngisho nangokuphathwa kabi ngesikhathi sokufakwa kanye nokususwa kokunyakaza.

Kumaphrojekthi okwakha amadolobha anokufakwa ngokulandelana (ukufakwa okufanayo okufakwa kabusha kuphrojekthi elandelayo ngemuva kokuqedwa kwephrojekthi yamanje), iphaneli ye-WPC ivame ukuqeda imijikelezo yokufakwa engu-4 kuya ku-8 ngaphambi kokudinga ukulungiswa noma ukushintshwa. Ukuvuselelwa kuvame ukukhawulelwa ekuvuseleleni okubonakalayo (ukusikwa okulula nokusetshenziswa kabusha kwe-topcoat engamelana ne-UV) kanye nokufakwa kabusha kwe-fastener encane, nesakhiwo sephaneli sihlala sinjalo. Ku-plywood, ukufakwa ngokulandelana akuvamile ukwenzeka ngoba ubuqotho bephaneli buvame ukwehluleka ngemva kokuvezwa kwephrojekthi eyodwa. Ku-corrugated metal, ukufakwa ngokulandelana kuyenzeka kodwa ukubukeka kwephaneli kungawohloka kakhulu emijikelezweni eminingi ngoba umonakalo womthelela kanye nokugqwala ezindaweni zokuxhuma kudala ukuwohloka kokubonakala okuqhubekayo okungase kungamukeleki kumaphrojekthi amadolobha abonakala kakhulu.

Ukuthobela Ukuphepha Komlilo: EN 13501-1 kanye nokuqhathaniswa kwesilinganiso se-ASTM E84

Ukuthobela imithetho yokuphepha emlilweni kuyindlela yesibili ebaluleke kakhulu yokucatshangelwa kokuqoqwa kwempahla yokwakha emadolobheni, futhi ikhodi yesakhiwo sendawo ivame ukucacisa isilinganiso esincane somlilo okumele sifinyelelwe ukuqoqwa kwempahla. Izindinganiso zokulinganisa umlilo ezibhekiselwe kakhulu yisistimu yokuhlukaniswa kwempahla ye-European EN 13501-1 (ehlukanisa izinto kusukela ku-A1 ezingashisi kuya ku-F ezingashisi) kanye nendinganiso ye-ASTM E84 yaseNyakatho Melika (ehlukanisa izinto kusukela ekusakazweni kwelangabi le-Class A 0-25 kuya ku-Class D ngaphezu kuka-200). Ukuqoqwa kwensimbi okune-corrugated kufeza i-EN 13501-1 Class A1 (okungashisi) ngokuzenzakalelayo ngenxa yesisekelo sensimbi, okuhlinzeka ngesilinganiso esiphezulu somlilo kodwa ngokushintshana kwezindleko eziphezulu ngesiqephu ngasinye kanye nenhlawulo yokusebenza kwe-acoustic. Ukuqoqwa kwempahla ye-WPC kuvame ukufeza i-EN 13501-1 Class B ngokungezwa kwezithasiselo ezivimbela umlilo ngesikhathi senqubo yokuhlanganisa.

Izithasiselo ezivimbela umlilo ezisetshenziswa ekwakhiweni kwe-WPC ngokuvamile ziyi-aluminium trihydrate (ATH), i-zinc borate, noma i-magnesium hydroxide, ngayinye emazingeni okulayisha angamaphesenti ayi-10 kuya kwangu-25 ngesisindo. Izinga lokulayisha elingeziwe linquma isilinganiso somlilo esingafinyeleleka, futhi esidume kakhulu. Umhlinzeki we-WpcI-s ingalungisa umthwalo owengeziwe ukuze ihlangabezane nesidingo sesilinganiso somlilo semakethe yendawo oya kuyo (Isigaba B nge-EN 13501-1 yincazelo ejwayelekile yokugcinwa kwezakhiwo zasemadolobheni ezimakethe zaseYurophu, kanti Isigaba C nge-ASTM E84 yincazelo ejwayelekile ezimakethe zaseNyakatho Melika). Isengezo sokuvimbela umlilo sithinta futhi izakhiwo zemishini zephaneli ye-WPC kanye nekhwalithi ebonakalayo, futhi umbiko wokuhlolwa komlilo womhlinzeki kufanele ufake imibhalo yekhwalithi ebonakalayo ukuqinisekisa ukuthi umthwalo we-anti-fire awuphazamisi ubuso bokubonisa uphawu.

Kumaphrojekthi okwakha emadolobheni lapho ukugcinwa kwempahla kufakwa eduze kwezakhiwo ezinabantu abaningi (imibhoshongo yokuhlala, izibhedlela, izikole, izikhungo zokuthenga), ikhodi yokwakha yendawo ingadinga isilinganiso somlilo se-Class A noma se-Class A2, lapho ukugcinwa kwe-WPC ngezithasiselo ezivimbela umlilo kungeke kwanelise isidingo futhi ukugcinwa kwensimbi ehlanganisiwe kuzoba yinketho kuphela ehambisanayo. Abathengi bamazwe ngamazwe abachaza ukugcinwa kwe-WPC kwamaphrojekthi okwakhiwa emadolobheni eduze kwezindawo ezibucayi kufanele bacele umbiko wokuhlolwa komlilo womhlinzeki futhi baqinisekise isilinganiso somlilo negunya lokulawula isakhiwo lendawo ngaphambi kokuqedela ukukhetha izinto. I-ASTM International ishicilela izindlela zokuhlola ezijwayelekile zokunquma izinga lomlilo, kanye IKomidi LaseYurophu Lokumisa Izindinganiso (CEN) ishicilela indlela yokuhlukanisa ye-EN 13501-1.

Ukusebenza kwe-Acoustic: I-WPC 25-32 dB vs Insimbi 12-18 dB nge-ISO 10140 ngayinye

Ukusebenza kwe-acoustic kuya ngokuya kuba yinto ecatshangelwayo kumaphrojekthi okwakha emadolobheni ngenxa yemithetho yomsindo wendawo ekhawulela umsindo wokwakha ngezikhathi ezibucayi (ngokuvamile kusihlwa, ngezimpelasonto, nasekuseni kakhulu ezindaweni zokuhlala nezindawo ezisetshenziswa ngokuxubile). Ukusebenza kwe-acoustic kokuqoqwa kwemisindo kulinganiswa njengokulahlekelwa komsindo emoyeni ngokwe-ISO 10140, futhi isilinganiso sithinta ngqo ukunciphisa umsindo okunikezwa yi-acoustic emphakathini ozungezile. Ukuqoqwa kwemisindo yokwakha ye-WPC ngokuvamile kufeza ukulahlekelwa komsindo okungu-25 kuya ku-32 dB kwephaneli ye-WPC engu-21 mm ubukhulu uma kuqhathaniswa no-12 kuya ku-18 dB kweshidi lensimbi elijwayelekile elihlanganisiwe elinobukhulu obulinganayo kanye no-18 kuya ku-25 dB kokuqoqwa kwe-plywood.

Inzuzo ye-acoustic ye-WPC iqhutshwa kakhulu yizici ezimbili zezinto ezibonakalayo: (1) ukuminyana okuphezulu (ngokuvamile okungu-1.2 kuya ku-1.4 g/cm³ kwe-WPC uma kuqhathaniswa no-0.7 kuya ku-0.9 g/cm³ kwensimbi ehlanganisiwe enobukhulu obufanayo) kunikeza isisindo esengeziwe ngeyunithi ngayinye ukuvimba ukudluliswa komsindo; (2) izici ze-viscoelastic damping ze-WPC compound (inhlanganisela ye-fiber yokhuni kanye ne-plastic matrix) zimunca amandla omsindo kunokuba ziwudlulisele, okuhlinzeka ngokunciphisa umsindo okwengeziwe ngale kokubikezela kwe-mass-law. Ukusebenza kwe-acoustic kwe-plywood kuphakathi nendawo, lapho ukuminyana okuphezulu kuqhathaniswa nensimbi kunikeza ukulahlekelwa okungcono kokudluliswa komsindo kodwa ukuminyana okuphansi uma kuqhathaniswa ne-WPC kunikeza ukumuncwa komsindo okuncane.

Kumaphrojekthi okwakha amadolobha aseduze nezindawo ezihlala abantu abazwela umsindo (ezokuhlala, ezempilo, ezemfundo), ukusebenza okuphezulu kwe-acoustic kwe-WPC hoarding kunikeza ukwehla okungu-10 kuya ku-15 dB ezingeni lomsindo womsebenzi wokwakha ofinyelela ezakhiweni ezizungezile, okungaba umehluko phakathi kokusebenza okuhambisanayo nokwephulwa komthetho womsindo ngezikhathi ezibucayi. Abathengi bamazwe ngamazwe abachaza i-WPC hoarding yezindawo zasemadolobheni ezizwela umsindo kufanele bacele umbiko wokuhlolwa kwe-acoustic we-ISO 10140 womhlinzeki ukuqinisekisa inani lokulahlekelwa komsindo wobukhulu bephaneli ethile ethengwayo, futhi umeluleki we-acoustic wephrojekthi kufanele axhumane ukuqinisekisa ukuthi ukunciphisa umsindo okubikezelwe endaweni kuhlangabezana nesidingo somthetho womsindo wendawo.

Iziqu Zomhlinzeki kanye Nokuhlanganiswa Kwephrojekthi Esendaweni Yokuthunyelwa Kwezindawo Zokugcina Izinto Zasemadolobheni

Kwabaphathi bephrojekthi yokwakha yasemadolobheni kanye nezikhulu zokuphepha zesayithi ezikhethe imininingwane yokugcinwa kwezakhiwo ze-WPC yesikhashana sendawo, iziqu zomhlinzeki kanye nokuhlanganiswa kwephrojekthi endaweni kuyisakhiwo sokusebenza (okubhekiselwe kuso yi- Isiqondiso sokuphepha kokwakhiwa kwe-NIOSH) okuqinisekisa ikhwalithi yokuthunyelwa ngakunye kanye neshejuli yokulethwa kwendawo yephrojekthi kuhambisana nesikhathi sephrojekthi yokwakha. Uhlaka lweziqu zomhlinzeki olunconyiwe lwethimba lethu luhlanganisa izilinganiso ezine: (1) ikhono lokukhiqiza, kufaka phakathi imishini yokuhlanganisa i-WPC (ama-extruder amabili ane-formulation enembile edingekayo ekulayisheni okungeziwe kwesilinganiso somlilo kanye nokulayisha kwe-UV stabilizer), imishini yokukhipha iphaneli (imigqa yokukhipha ngokubambisana yesicelo sesendlalelo se-cap), imishini yokukhiqiza ngemuva (ukusika nokushisela ngemuva kwensimbi), kanye nokwenziwa kwezesekeli (iziqeshana zokuxhuma kanye nezinamathiselo zesikulufo); (2) uhlelo lokuphatha ikhwalithi, kufaka phakathi ukwakheka kwe-compound okubhaliwe, ukulandeleka kwe-compound nge-batch, amarekhodi okuhlola ubukhulu bephaneli aqediwe, kanye nemibiko yokuhlola izilinganiso zomlilo emakethe yokuya kuyo; (3) ikhono lokunikeza iphrojekthi, kufaka phakathi ikhono lokukhiqiza iphaneli lesikhathi sephrojekthi, isikhundla sempahla yephaneli esiqediwe, izinto zokulethwa endaweni yephrojekthi yasemadolobheni, kanye nokwabiwa kwethimba lokuphatha iphrojekthi; (4) iwaranti kanye nokusekelwa kwangemva kokuthengisa, okuhlanganisa nenqubomgomo yokushintsha amaphaneli ngomonakalo ombozwe yiwaranti, insizakalo yokuhlola endaweni yokufaka iphrojekthi, kanye nensizakalo yokuvuselela yokudluliselwa kwephrojekthi ngemva kwephrojekthi.

Sihlala sisekela amakhasimende ethu enqubweni yokufaneleka komhlinzeki ngokunikeza imibhalo yokwakheka (iphakheji yokwengeza ehlanganisiwe ngokwesilinganiso somlilo semakethe yendawo kanye nezidingo zokuchayeka kwe-UV), isitifiketi senhlanganisela ngeqembu ngalinye (ibanga le-resin, okuqukethwe kwefayibha yokhuni, ukwakheka kwephakheji yokwengeza), umbiko wokuhlolwa kwephaneli oqediwe ngeqembu ngalinye (ubukhulu, ubuhle, isilinganiso somlilo), kanye neshejuli yokukhiqiza ethize yephrojekthi enokubonakala kwento ebalulekile. Iphrothokholi yokuhlola engenayo enconyiwe yeqembu lethu ngeqembu ngalinye yokuthengwa kwe-WPC hoarding ihlanganisa isampula yezingcezu ezingu-30 ngeqembu ngalinye lokuqinisekiswa kobukhulu (ubude, ububanzi, ukujiya, ukunemba, ukuthamba), umbala kanye nokuqinisekiswa kobuhle (ngokumelene nesampula yokubhekisela ngeqembu ngalinye), ukuhlolwa kwendawo yesilinganiso somlilo (njalo ezinyangeni ezi-6 zomkhankaso wokukhiqiza ngokwesidingo sokuqinisekiswa kwemakethe yendawo), kanye nedokhumenti yesithombe ngephakethe ngalinye ngaphambi kokulayisha isitsha. Isampula ngeqembu ngalinye ivame ukuhlolwa elabhorethri yamakhasimende ethu noma elabhorethri yokuhlola yomuntu wesithathu ukuqinisekisa ukuvumelana okubikiwe komhlinzeki.

Ngokuhlanganisa iphrojekthi endaweni, isincomo sethimba lethu ukuvumelanisa isimiso sokukhiqiza somhlinzeki nesikhathi sokuhambisa iphrojekthi yokwakha, lapho ukukhiqizwa kwephaneli kuqediwe amasonto ama-4 kuya kwayi-6 ngaphambi kosuku lokuhambisa iphrojekthi ukuze kuvunyelwe ukuhlolwa kweqembu ngalinye, ukulayishwa kwesitsha, ukuthutha imithwalo yolwandle, kanye nokulethwa endaweni yendawo yephrojekthi edolobheni. Sisekela amakhasimende ethu ekuxhumaniseni ukulethwa endaweni, ukuhlolwa kweqembu ngalinye echwebeni lokuya kulo, kanye nokuqapha ukufakwa endaweni uma kudingeka yisikhulu sezokuphepha kwephrojekthi. Okuhlangenwe nakho kwethimba lethu kulo lonke isisekelo sokulethwa kwempahla yokwakha yasemadolobheni kukhombisa ukuthi isikhathi esijwayelekile sokuhola ngephrojekthi kusukela ekukhiqizeni kokuqala komhlinzeki kuya ekuqedeni ukufakwa endaweni singamaviki ayi-10 kuya kwayi-14, kanti isikhathi eside kakhulu sokuhola yisithuthi semithwalo yolwandle (ngokuvamile amasonto ama-4 kuya kwayi-6 emizileni edlula ePacific noma e-Asia-Europe).

Imibuzo Evame Ukubuzwa Emaqenjini Okuthenga Amasheya Okwakha Emadolobheni

Iyiphi impilo ejwayelekile yenkonzo yokugcinwa kwe-WPC uma kuqhathaniswa nokugcinwa kwe-plywood ne-metal?
Impilo ejwayelekile yenkonzo yokuqoqa i-WPC (wood-plastic composite) ekwakheni izakhiwo zasemadolobheni iyiminyaka engu-8 kuya kwengu-15 phakathi kwemijikelezo eminingi yephrojekthi ngokulungiswa okufanele, idlula kakhulu ukuqoqwa kwe-plywood okujwayelekile izinyanga ezi-3 kuya kwezingu-12 ngephrojekthi ngayinye kanye nokuqoqwa kwensimbi ehlanganisiwe okujwayelekile iminyaka emi-3 kuya kwemi-5 phakathi kwemijikelezo eminingi yephrojekthi. Inzuzo yokuqina kwe-WPC ivela ekuphikiseni kwezinto ezisetshenziswayo ekumuncweni komswakama (ngaphansi kwephesenti eli-1 lokumuncwa kwamanzi nge-ASTM D570 uma kuqhathaniswa namaphesenti angu-8 kuya kwangu-15 e-plywood yezinga lokwakha), ukwakheka kwayo okuhlanganisiwe okuzinzile kwe-UV okumelana nokufiphala kombala kanye nokushiswa kobuso, ukumelana kwayo nokuwohloka kwezinto eziphilayo (akukho kubola, akukho sikhunta, akukho monakalo wezintuthwane), kanye nokumelana kwayo nomthelela womshini okumelana nokuqhekeka nokubhoboka okuvamile ezindaweni zokwakha. Impilo yesevisi elindelekile yephaneli yokubeka i-WPC iqhutshwa izindlela ezintathu eziyinhloko zokuwohloka: (1) ukufiphala kombala okubangelwa yi-UV (okuqondiswa ngokungezwa kweziqinisi ze-UV ekwakhiweni okuhlanganisiwe), (2) umonakalo womthelela womshini (okuqondiswa ungqimba lwesivalo sephaneli esihlanganisayo esimunca imihuzuko kanye nemithelela), kanye (3) ukukhathala kwesibambo ekuxhumekeni kwephaneli kuya kokuthunyelwe (okuqondiswa incazelo yesibambo sensimbi engagqwali). Kumaphrojekthi okwakha amadolobha anobude bezinyanga ezingu-18 kuya kwezingu-36, ukugcinwa kwesibambo se-WPC kuvame ukusinda kuphrojekthi ngokulungiswa okuncane kwendawo futhi kungaphinde kusetshenziswe kumaphrojekthi alandelayo, kunciphisa kakhulu izindleko ezikhokhisiwe ngephrojekthi ngayinye.

Ukuqoqwa kwe-WPC kuqhathaniswa kanjani nokuqoqwa kwe-plywood kanye ne-metal ngokuhambisana nokuphepha komlilo?
Ukugcinwa kwe-WPC ngokwakha kuvame ukufeza isilinganiso somlilo se-Class B ngokwezinga le-European EN 13501-1 (elilingana ne-ASTM E84 Class B eNyakatho Melika), ngokufakwa kwezithasiselo ezivimbela umlilo ngesikhathi senqubo yokuhlanganisa. Ukugcinwa kwensimbi ekhonkrithiwe kufinyelela i-Class A1 (engashi) ngokwe-EN 13501-1 ngokuzenzakalelayo, okuhlinzeka ngesilinganiso somlilo esiphezulu kodwa ngezindleko eziphakeme ngesiqephu ngasinye, isisindo sokufakwa esinzima, kanye nokusebenza okuphansi kwe-acoustic. Ukugcinwa kwe-plywood ngokuvamile kufinyelela isilinganiso se-Class D kuya ku-Class C kuye ngokwelashwa, nge-plywood engalashwanga elinganiselwe njenge-Class D (isilinganiso esiphansi kakhulu esamukelekayo ezindaweni eziningi zasemadolobheni) kanye ne-plywood evikelwe umlilo elinganiselwe njenge-Class C. Kumaphrojekthi okwakha amadolobha lapho ukugcinwa kwe-plywood kufakwa eduze kwezakhiwo ezinabantu, imfuneko yesilinganiso somlilo ngokuvamile i-Class B noma ngaphezulu ngokwekhodi yesakhiwo sendawo, kanti ukugcinwa kwe-WPC nge-additive evimbela umlilo kuhlangabezana nale mfuneko ngezindleko ezincintisanayo ngesiqephu ngasinye. Abathengi bamazwe ngamazwe kufanele bacele umbiko wokuhlolwa komlilo womhlinzeki ngokwe-EN 13501-1 noma i-ASTM E84 ukuqinisekisa ukuthi isilinganiso somlilo sifinyelelwa njalo kuzo zonke izinhlobo zokukhiqiza, futhi uhlobo lwesengezo esivimbela umlilo (ngokuvamile i-aluminium trihydrate noma i-zinc borate) kufanele luchazwe eshidini ledatha yezinto ezibonakalayo.

Yimuphi umsebenzi we-acoustic ohlinzekwa yi-WPC hoarding uma kuqhathaniswa nensimbi ne-plywood?
Ukugcinwa kwe-WPC ngokwakhiwa kuhlinzeka ngokusebenza kwe-acoustic okuphezulu kakhulu uma kuqhathaniswa nokugcinwa kwensimbi ehlanganisiwe, kanye nokulahlekelwa kokudluliselwa komsindo emoyeni ngokwe-ISO 10140 ngokuvamile kusuka ku-25 kuya ku-32 dB kwephaneli ye-WPC enobukhulu obungu-21 mm uma kuqhathaniswa no-12 kuya ku-18 dB kweshidi lensimbi ehlanganisiwe elijwayelekile elinobukhulu obulinganayo. Inzuzo ye-acoustic ye-WPC iqhutshwa kakhulu ukuxinana okuphezulu kwezinto (ngokuvamile kusuka ku-1.2 kuya ku-1.4 g/cm³ ye-WPC uma kuqhathaniswa no-0.7 kuya ku-0.9 g/cm³ yensimbi ehlanganisiwe enobukhulu obulinganayo) kanye nezici zokunciphisa i-viscoelastic zezinto ezimunca amandla omsindo kunokuba ziwadlulisele. Kumaphrojekthi okwakha amadolobha aseduze nezakhiwo zokuhlala noma zezentengiselwano ezihlalwa ngabantu, ukusebenza kwe-acoustic kokugciniwe kuyisici esibalulekile sokucatshangelwa ngoba umthetho womsindo wendawo uvame ukunciphisa umsindo womsebenzi wokwakha ngesikhathi samahora abucayi, futhi ukugcinwa kwe-acoustic okuphezulu kunciphisa umthwalo womsindo emphakathini ozungezile. Ukugcinwa kwe-plywood kunikeza ukusebenza kwe-acoustic okuphakathi kwe-WPC nensimbi (ngokuvamile kusuka ku-18 kuya ku-25 dB) kodwa ngesikhathi sempilo yesevisi emfushane kakhulu. Abathengi bamazwe ngamazwe abachaza ukuqoqwa kwe-WPC ezindaweni zasemadolobheni ezizwela umsindo kufanele bacele umbiko wokuhlolwa kwe-acoustic we-ISO 10140 womhlinzeki ukuqinisekisa inani lokulahlekelwa kokudlulisa umsindo ngenxa yobukhulu bephaneli ethile etholakalayo.

Amaphaneli okugcina i-WPC kufanele afakwe kanjani endaweni evamile yokwakha yasemadolobheni?
Ukufakwa kwephaneli yokubeka i-WPC kulandela inqubo ejwayelekile yezinyathelo ezintathu eshesha kakhulu kune-corrugated metal equivalent: (1) ukuhlola indawo kanye nokuhlelwa kweposi, ngezikhundla zeposi ezimakwe ngezikhawu zamamitha angu-2.0 kuya kwangu-2.5 kuye ngesidingo somthwalo womoya wendawo, (2) ukufakwa kweposi kusetshenziswa izinsika zensimbi ezifakwe ukhonkolo noma izinsika zensimbi eziqhutshwayo ezinekhola yekhonkolo, ngosayizi weposi okhethiwe ngokwezinga lomthwalo womoya wendawo (ngokuvamile ingxenye yesikwele engu-50 mm × 50 mm kuya ku-80 mm × 80 mm ukuphakama kweposi engu-2.5 metres), kanye (3) ukufakwa kwephaneli ngokuslayida imiphetho yolimi nomgodi wephaneli ye-WPC eziteshini zeposi bese uzifaka ngeziqeshana zensimbi engagqwali noma izikulufo zokuzithinta. Isikhathi somjikelezo wokufakwa kwesigaba esijwayelekile sokuqoqwa kwempahla emadolobheni (amamitha angu-30 aqondile) cishe amahora angu-4 kuya kwangu-6 eqenjini labantu abane abasebenzisa amaphaneli e-WPC, uma kuqhathaniswa namahora angu-6 kuya kwangu-10 okufakwa okufanayo kokuqoqwa kwempahla yensimbi ngenxa yesisindo sephaneli esilula (ngokuvamile 8 kuya ku-12 kg ngephaneli ye-WPC uma kuqhathaniswa no-18 kuya ku-25 kg ngeshidi lensimbi) kanye nohlelo lokuxhuma ulimi nomgodi oluhlanganisiwe. Umjikelezo wokuhlukaniswa kokususwa kwephrojekthi ushesha ngendlela efanayo, ngamaphaneli e-WPC avame ukusetshenziswa kabusha izikhathi ezingu-4 kuya kwezingu-8 kumaphrojekthi asemadolobheni alandelanayo kuye ngesimo sephaneli. Abathengi bamazwe ngamazwe abachaza ukuqoqwa kwempahla e-WPC kufanele baqinisekise uhlelo lokuposa olunconyiwe lomhlinzeki (oluhambisana nobunikazi noma lomuntu wesithathu), imininingwane yokuxhumeka kwephaneli nokuthunyelwa, kanye nesilinganiso esiphezulu somthwalo womoya ngokwezinga lendawo.

Iyini indlela yokulahla amaphaneli okugcina izimpahla e-WPC ekupheleni kokuphila?
Amaphaneli okugcina izinto ezakhiweni ze-WPC asefinyelele ekupheleni kokuphila kwawo angaphinde asetshenziswe ngokugaya ngomshini nokuhlanganisa kabusha imikhiqizo emisha ye-WPC, lapho i-WPC equkethe izinto eziphinde zasetshenziswa inokusebenza okulinganayo ne-WPC engeyona eyemvelo kwezicelo eziningi ezingezona ezesakhiwo okuhlanganisa ukuhlanganisa okwesibili, izingcezu zocingo, kanye nokubiyela indawo. Inqubo yokuvuselela izinto ngokuvamile ihilela ukuqoqwa kwamaphaneli okuphela kokuphila, ukugaya ngomshini kube ama-chips angu-5 kuya ku-10 mm, ukususwa kwensimbi (ezifakelweni ezifakiwe nanoma yikuphi ukuqinisa insimbi), ukugeza ukuze kususwe ukungcola komhlaba, kanye nokuhlanganisa kabusha ngezinto ezengeziwe ze-WPC engeyona eyemvelo kanye nezithasiselo ukukhiqiza i-WPC equkethe izinto eziphinde zasetshenziswa. Ukuqoqa izinto ezenziwe nge-corrugated metal kungasetshenziswa kabusha ngochungechunge lokuvuselela izinto ezisele zensimbi, kodwa ukuxhumana kwephaneli neposi kuvame ukuholela emfucumfucwini yezinto ezixubile ezidinga ukuhlukaniswa ngaphambi kokuvuselela izinto. Ukuqoqa izinto ezenziwe nge-plywood kuvame ukuya endaweni yokulahla imfucuza noma ekubuyiselweni kwamandla e-biomass ngoba amakhemikhali okwelapha izinkuni (ikakhulukazi ukwelashwa okuvimbela umlilo) kukhawulela izinketho zokuvuselela izinto. Kumaphrojekthi okwakha amadolobha abeka phambili isitifiketi se-LEED, isitifiketi se-BREEAM, noma ukuhambisana nesilinganiso sezakhiwo eziluhlaza zasendaweni, ukuphinde kusetshenziswe kwe-WPC hoarding kunegalelo ekunikezelweni kwesikweletu sokuchithwa kwemfucuza yokwakha futhi kusekela umgomo wokuzinza wephrojekthi. Abathengi bamazwe ngamazwe abachaza ukuqoqwa kwe-WPC kufanele bacele imibhalo yenqubo yokuphinda kusetshenziswe yomhlinzeki ekupheleni kokuphila futhi baqinisekise iphesenti lokuqukethwe okuphinde kusetshenziswe elitholakalayo emjikelezweni olandelayo wephrojekthi.

Kwabaphathi bephrojekthi yokwakha yasemadolobheni, izikhulu zokuphepha endaweni, kanye namaqembu okuthenga ucingo lwesikhashana ahlola ukugcinwa kwezakhiwo ze-WPC, ithimba lokuthumela ngaphandle le-Yida Wood-Plastic linikeza isiqondiso semininingwane ye-WPC (ukukhethwa kwesengezo sokulinganisa umlilo, ukulayishwa kwe-UV stabilizer, iphesenti lokuqukethwe okuphinde kwasetshenziswa), ukwenza ngokwezifiso ubukhulu bepherimitha ethile yephrojekthi, ukuhlanganiswa kombiko wokuhlolwa komlilo we-EN 13501-1 kanye ne-ASTM E84, ukuhlanganiswa kombiko wokuhlolwa kwe-acoustic we-ISO 10140, kanye nokuhlela ukulethwa endaweni yezindawo zemijikelezo yephrojekthi elandelanayo. Xhumana nathi nge-imeyili yethu. Ikhasi lokuxhumana le-Yida Wood-Plastic nendawo yephrojekthi yakho, isidingo sakho semitha eqondile yokuqoqa, izidingo zakho zesilinganiso somlilo sendawo kanye nomthetho womthetho womsindo, kanye nobude besikhathi sephrojekthi yakho. Inani eliphansi le-oda lekhathalogi elijwayelekile yizingcezu ezingu-5,000 ngokwenqubomgomo yomkhiqizo yomhlinzeki; ukwenza ngokwezifiso i-OEM (ubukhulu ngokwezifiso, ukulayisha okwenziwe ngokwezifiso okuvimbela umlilo, iphakheji ye-UV-stabilizer eyenziwe ngokwezifiso, umbala owenziwe ngokwezifiso) kuyatholakala ngenani elincane le-oda lezingcezu ezingu-50,000.
