Ukumbozwa Kwe-WPC vs Ukumbozwa Kwezinkuni Zendabuko: Ukuhlaziywa Kwezindleko Nezinzuzo Kwabakhi Bezentengiselwano
Izinto Ezibalulekile Okufanele Uzicabangele
- I-WPC (i-wood-plastic composite) i-co-extrusion cladding ibiza ama-20-35% kusengaphambili kune-softwood elungisiwe kodwa inikeza izindleko zokulungisa eziphansi ngama-60-75% esikhathini sokuphila kweminyaka engama-20.
- Ubuchwepheshe be-co-extrusion budala igobolondo le-polymer elivikelayo elizungeze umongo we-WPC, lihlinzeka ngokuqina kwe-UV, ukumelana nomswakama, kanye nokugcinwa kombala okudlula ngisho nokumbozwa kokhuni oluqinile lwekhwalithi ephezulu.
- Abakhi bezentengiselwano eYurophu naseNyakatho Melika bashintshela ekufakweni kwe-WPC ngoba I-ASTM D7032 kanye nokuhambisana ne-EN 15534 kwenza kube lula ukuvunyelwa kwekhodi yokwakha ngenkathi kususwa ukulungiswa kwaminyaka yonke kokufaka idayi nokuvala okudingwa yizimbobo zokhuni.
- Izindleko eziphelele zeminyaka engama-20 zobunikazi be-WPC cladding ziphansi ngo-35-50% kunezinkuni uma kufakwa esikhundleni sezinto zokwakha, umsebenzi wokulungisa kabusha, kanye nezindleko zokulahla ekupheleni kokuphila.
Izindleko Zangempela Zokumbozwa Kwezinkuni Okungekho Okhuluma Ngazo Esigabeni Sokubhida
Ngichithe iminyaka eyishumi edlule ngisiza abathumeli bezinto zokwakha eYurophu, eNyakatho Melika, naseNingizimu-mpumalanga ye-Asia. I-Wpc Decking, uthango, kanye nokubopha okuvela ezimbonini zaseShayina. Ingxoxo cishe njalo iqala ngendlela efanayo: umakhi wezakhiwo uchaze ukugoba kokhuni (ngokuvamile i-western red cedar, i-larch, noma i-thermowood pine), umakhi ubiza intengo yezinto zokwakha kanye nokufakwa, bese iphrojekthi iqhubekela phambili nalokho okubonakala kuyisisombululo esingabizi kakhulu.
Lokho ibhidi lokuqala elingakuhlanganisi yizindleko zokulungisa eziqongelela njalo ngonyaka ngemva kokufakwa. Ukumbozwa kwezingodo kudinga ukudaya noma ukugcotshwa ngamafutha njalo eminyakeni emi-2-5 kuye ngohlobo, ukuchayeka, kanye nohlobo lokuqeda. ENyakatho Yurophu, lapho imvula, isithwathwa, kanye nokuchayeka kwe-UV kukhulu khona, isakhiwo sezentengiselwano esinombozo wezingodo ongama-500 square metres sizosebenzisa u-$3,000-6,000 ngomjikelezo ngamunye wokulungisa ezinsikeni, emsebenzini, nasezintweni zokwakha - njalo eminyakeni emi-3, impilo yonke yesakhiwo.
Uma ngibonisa osonkontileka nabanikazi bezakhiwo ukuqhathaniswa kwezindleko zomjikelezo wokuphila kweminyaka engama-20 phakathi kokumbozwa kwezinkuni zendabuko kanye nokumbozwa kwe-WPC co-extrusion, izinombolo zihlala zikhetha i-WPC ngenani elikhulu. Nansi indlela lokho kuhlaziya okusebenza ngayo.
Kuyini i-WPC Co-Extrusion Cladding futhi Kwenziwa Kanjani?
I-WPC (i-wood-plastic composite) iyinto eyenziwe ngobunjiniyela eyenziwe ngengxube yefayibha yokhuni (ngokuvamile i-50-60%), i-thermoplastic polymer (i-HDPE noma i-PP, i-30-35%), kanye nezengezo zokusebenza (5-15%) kufaka phakathi iziqinisi ze-UV, imibala yombala, ama-coupling agents, kanye nama-fungicides. Ingxube iyashiswa, ixutshwe, futhi ikhishwe nge-die ukuze yakhe amabhodi ane-cross-section efanayo.
Ukuhlanganiswa kwe-co-extrusion kuyintuthuko ebalulekile ehlukanisa ukumbozwa kwe-WPC yesimanje nemikhiqizo ehlanganisiwe yesizukulwane sokuqala. Enqubweni yokukhipha ndawonye, i-extruder yesibili isebenzisa ungqimba lwesivalo se-polymer esivikelayo (ngokuvamile ubukhulu obungu-0.3-0.7mm) sizungeze umongo we-WPC njengoba siphuma kudayi oyinhloko. Lolu ngqimba lwesivalo - olwakhiwe ngezithiyo ze-UV ezigxilile kanye nemibala - ludala indawo evaliwe evikela umongo we-wood-fiber ekungeneni komswakama kanye nokuwohloka kwe-UV.
Umphumela uba ibhodi lokumboza elibukeka njengokhuni lwemvelo (ngenxa yamaphethini okusanhlamvu aqoshiwe kungqimba lwesivalo) kodwa lisebenza njenge-polymer esebenza kahle kakhulu. I-WPC co-extrusion cladding YD216H25 ikhiqizwa emugqeni we-co-extrusion ozenzakalelayo ngokuphelele ngokuqapha ukujiya kwe-cap ngesikhathi sangempela ukuqinisekisa ukuvikelwa okuqhubekayo kuyo yonke imitha eqondile. Siphinde sakha imikhiqizo ehambisanayo — yamaphrojekthi adinga iphakheji ephelele yangaphandle, yethu Uhla lothango lwe-WPC inebuchwepheshe obufanayo bokukhipha kanye nohlelo lokufanisa imibala.
Ukuqhathaniswa Kwezindleko Zomjikelezo Wempilo Weminyaka Engama-20: I-WPC vs I-Timber Cladding
| Isigaba Sezindleko | Izinkuni Ezithambile Eziphathwe Kahle (Iphayini/I-Larch) | Ukhuni Oluqinile Olusezingeni Eliphezulu (iCedar/Ipe) | Ukumbozwa kwe-WPC Co-Extrusion |
|---|---|---|---|
| Izindleko zezinto (nge-m² ngayinye) | $25-40 | $60-120 | $35-55 |
| Izindleko zokufaka (nge-m² ngayinye) | $15-25 | $20-35 | $15-25 |
| Isamba sokuqala (nge-m²) | $40-65 | $80-155 | $50-80 |
| Izindleko zokulungisa zonyaka (nge-m²) | $3-6 (ukufaka idayi/ukuvala) | $2-4 (ukufaka uwoyela) | $0 (akukho ukulungiswa) |
| Ukulungiswa okukhulu (njalo eminyakeni emi-5, nge-m² ngayinye) | $8-15 | $5-10 | $0 |
| Ukufakwa esikhundleni kwebhodi (iminyaka engama-20, indawo engu-10%) | $4-8 | $6-15 | $0-2 |
| I-TCO Yeminyaka Engama-20 (nge-m² ngayinye) | $110-180 | $120-220 | $52-85 |
Ngenxa yokuthi ukumbozwa kwe-WPC co-extrusion akudingi ukulungiswa kwaminyaka yonke — akukho ukudaya, akukho ukuvala, akukho ukugcotshwa ngamafutha — izindleko eziphelele zeminyaka engu-20 zobunikazi ziphansi ngo-35-50% kunezinkuni ezithambile ezilungisiwe kanye no-55-65% ngaphansi kunezinkuni eziqinile zekhwalithi ephezulu. Lezi zinombolo ziba zinkulu nakakhulu uma ubheka izindleko ze-scaffolding zezakhiwo zezentengiselwano ezinezitezi eziningi, lapho umjikelezo owodwa wokulungisa ungabiza u-$10,000-20,000 ngemishini yokufinyelela kuphela.
Ukuqhathaniswa Kokusebenza: Umswakama, i-UV, kanye nokumelana nezinambuzane
Kwabakhi bezentengiselwano, izindlela zokusebenza ezibaluleke kakhulu ukuzinza kobukhulu bokujikeleza komswakama, ukugcinwa kombala ngaphansi kokuchayeka ku-UV, kanye nokumelana nokuhlaselwa kwezinto eziphilayo (izinambuzane nesikhunta).
- Ukumuncwa komswakama: Ukumbozwa kwezingodo kumunca umswakama ongu-12-25% ngesisindo uma kugcwele, okubangela ukuvuvukala, ukugoba, kanye nokugoba. Ukumbozwa kwe-WPC co-extrusion kumunca umswakama ongaphansi kuka-1% ngesisindo - ungqimba lwesivalo se-polymer luvala umongo we-fiber yokhuni ekuthinteni ngqo kwamanzi. Lokhu kusho ukuthi amabhodi e-WPC agcina ukubekezelelana kwawo ngobukhulu phakathi kwemijikelezo yemvula, iqhwa, kanye nomswakama ngaphandle kwezikhala zokukhula kanye nokulungiswa okudingwa ukumbozwa kwezingodo.
- Ukumelana ne-UV: Izinkuni ezingavikelwe ziwohloka ngaphansi kwemisebe ye-UV — i-lignin ku-fiber yokhuni iyawohloka, okwenza ubuso bube mpunga futhi bube bushelelezi zingakapheli izinyanga ezingu-6-12 zokuchayeka. Ngenkathi abanye abakhi bezakhiwo bekwazisa lokhu kuguquka kwemvelo, abanikazi bezakhiwo zezentengiselwano ngokuvamile abakuboni lokhu. I-WPC co-extrusion cladding igcina umbala wayo wokuqala iminyaka engu-15-25 ngoba ungqimba lwesivalo luqukethe iziqinisi ze-UV ezigxilile (ngokuvamile i-HALS — iziqinisi zokukhanya ze-amine ezivinjiwe — ekulayisheni okungu-2-4%) ezimunca futhi zichithe amandla e-UV ngaphambi kokuba zifinyelele enkabeni ye-fiber yokhuni.
- Ukumelana nezinambuzane kanye nesikhunta: Ukumbozwa kwezingodo kusengozini yezintuthwane, izimbungulu ezibhoboza ukhuni, kanye nokubola kwesikhunta — ikakhulukazi ezindaweni ezifudumele nezinomswakama. Ukumbozwa kwe-WPC kuqukethe izithasiselo zesikhunta kanye nezinambuzane ezixutshwe enkombeni eyinhloko ngesikhathi sokukhiqiza, okuhlinzeka ngokuvikelwa kwezinto eziphilayo okwakhelwe ngaphakathi ngaphandle kokwelashwa ngamakhemikhali ngemva kokukhiqizwa.
Ukusebenza Komlilo kanye Nokuthobela Imithetho Yesakhiwo
Ukusebenza komlilo kuyisici esibaluleke kakhulu sezinto zokumboza ezentengiselwano, ikakhulukazi eYurophu ngemuva kwenhlekelele yeGrenfell Tower kanye nokuqiniswa kwemithetho yokwakha okwalandela kulo lonke elase-EU. Nakhu lapho ukumboza kwe-WPC kumi khona endaweni yokusebenza komlilo:
I-WPC cladding ejwayelekile (ngaphandle kwezithasiselo ezivimbela umlilo) ivame ukufeza isilinganiso se-Class C noma se-Class D ngaphansi kohlelo lwe-European EN 13501-1 lokuhlukanisa umlilo, oluhambisana nokusabela komlilo okufana nokhuni oluphakathi nendawo. Ezakhiweni zezentengiselwano ezidinga ukusebenza komlilo we-Class B, kutholakala amafomula e-WPC avimbela umlilo afaka ama-mineral fillers (i-aluminium trihydrate, i-magnesium hydroxide) ngokulayisha okungu-10-20%.
Isimbozo sethu se-WPC co-extrusion esinefomula evimbela umlilo sihlolwe ku-EN 13501-1 Class B-s1,d0, esihlangabezana nezidingo zezakhiwo ezingaphezu kwamamitha ayi-18 ezindaweni eziningi zaseYurophu. Isithako esivimbela umlilo sifakwa engxenyeni eyinhloko ngesikhathi sokukhiqiza — akuyona ingubo engaphezulu engaguga ngokuhamba kwesikhathi. Lokhu kusho ukuthi ukusebenza komlilo kuyingxenye yezinto ezibonakalayo futhi akuwonakali lapho kushiswa yisimo sezulu.
Kumaphrojekthi aseNyakatho Melika, ukumbozwa kwe-WPC kumele kuhambisane ne-ASTM E84 (ukuhlolwa komhubhe we-Steiner) kokusabalala komlilo kanye nokuthuthukiswa komusi. Amafomula ajwayelekile e-WPC ngokuvamile afinyelela isilinganiso se-Class A noma se-Class I (inkomba yokusabalala komlilo 0-25, inkomba ethuthukiswe ngomusi 0-450) uma ihlolwa ngokwe-ASTM E84.
Ukusebenza Kahle Kokufaka: Indlela i-WPC Enciphisa Ngayo Izindleko Zabasebenzi Esizeni
Ngale kokusebenza kwezinto ezibonakalayo, ukumbozwa kwe-WPC co-extrusion kunikeza izinzuzo eziningana zokufakwa ezihumusha ngqo ekongeni izindleko zabasebenzi kumaphrojekthi ezentengiselwano:
- Uhlelo lweziqeshana ezifihliwe. I-YD216H25 cladding yethu isebenzisa i-clip yensimbi engagqwali efihliwe eshelela esiteshini sangaphakathi sebhodi. Akukho ukubethela ubuso, akukho zibopho ezibonakalayo, futhi ibhodi ngalinye lingena kwelinye ngesikhala esifanayo. Lolu hlelo lushesha ngo-30-40% ukufakwa kune-cladding yokhuni eqiniswe ubuso ngoba umfakisi akadingi ukubhoboza kusengaphambili, ukucwilisa kabili, noma ukuqondisa izipikili ngazinye.
- Akudingeki ukwelashwa kwangaphambi kwesikhathi. Amabhodi okubopha izingodo avame ukudinga ukuvalwa kokugcina, ukugcwalisa amafindo, kanye nokufakwa kombala ngaphambi kokufakwa. Amabhodi e-WPC alungele ukufakwa ngqo kusuka ephaketheni - asikwe ngobude, asikwe, bese ethuthelwa ebhodini elilandelayo.
- Ukubekezelelana okulinganayo okulinganayo. Amabhodi e-WPC akhishwe efektri agcina ukubekezelelana kobukhulu obungu-±0.5mm kulo lonke umjikelezo wokukhiqiza. Amabhodi emvelo ezinkuni angahluka ngobubanzi obungu-2-5mm kanye nobukhulu phakathi kwamabhodi, okudinga ukuhlunga nokukhethwa endaweni. Ubukhulu obuhambisanayo be-WPC busho ukuhlangana okufanayo kanye nokufakwa okusheshayo nokubikezelwayo.
- Isisindo esilula. Amabhodi okumboza e-WPC anesisindo esingaba ngu-2.0-2.5 kg ngemitha ngayinye eqondile (kumabhodi angu-216mm ububanzi), uma kuqhathaniswa no-3.0-4.5 kg wamabhodi okhuni alinganayo. Lokhu kunciphisa isisindo kunciphisa ukukhathala komfaki, kwenza kube lula ukuthutha izikafula, futhi kunciphisa umthwalo wesakhiwo emvilophini yesakhiwo.
Imibono Engalungile Evamile Mayelana Nokumbozwa Kwe-WPC
Ngokwazi kwami ukusiza abasabalalisi ukuthi bashintshele kusuka kokhuni baye ku-WPC, ngihlangana nemibono efanayo eyiphutha ngokuphindaphindiwe. Ukubhekana nalokhu kusengaphambili kuvimbela amaphutha abizayo:
Umbono Oyiphutha 1: "I-WPC ibukeka sengathi iwumbumbulu." I-WPC yesizukulwane sokuqala yayinokwakheka okufanayo nokuphindaphindayo. I-co-extrusion yesimanje ikhiqiza amaphethini ezinkuni aqoshwe ngokujulile anemibala ehlukahlukene yemvelo. Ebangeni lokubuka elingamamitha angu-3-5 (elijwayelekile kuma-facade), ngisho nabakhi abanolwazi abakwazi ukuhlukanisa i-WPC esezingeni eliphezulu nokhuni ngaphandle kokuyithinta. Umkhiqizo wethu usebenzisa ama-roller aqoshwe nge-CNC anamaphethini ezinhlamvu avela kumasampula ezinkuni zangempela, okudala ukuhlukahluka kokujula okungu-0.5-0.8mm.
Umbono Oyiphutha 2: "I-WPC inzima kakhulu ukuthi ingafakwa kabusha." Njengoba inobukhulu obungu-2.0-2.5 kg ngemitha eqondile ebhodini elingu-216mm ububanzi, i-WPC ilula kuneziningi zezindwangu zokhuni. Ukukhathazeka kuvame ukubangelwa ukudideka ngamabhodi okulenga esakhiwo. Amabhodi okulenga awawona awesakhiwo futhi asebenza ngezinhlaka ze-batten ezijwayelekile.
Umbono Ongaqondile 3: "I-WPC ayikwazi ukusingatha ama-curve." Nakuba i-WPC ingenakugoba ngokubandayo njengokhuni oluncane, ukwakha ukushisa kuvumela ukwakheka kwama-curve athambile (i-radius engaphezu kwamamitha angu-3-4). Kuma-curve aqinile, amaphrofayili e-WPC aguquguqukayo anama-cores amancane avumela ama-radii afinyelele kumamitha ama-2 uma eshiswa afike ku-80-100 degrees C.
Ngenxa yokuthi le mibono eyiphutha iholela abaklami bezakhiwo ukuba benqabe i-WPC ngaphandle kokuhlolwa okufanele, ngincoma ukuthi nginikeze amabhodi esampula angokoqobo ukuze kwenziwe ama-mock-up endaweni. Uma umakhi ebona isampula ye-WPC engamamitha angu-3x3 eceleni kwencazelo yokhuni, ukuqhathanisa cishe njalo kuthanda i-WPC ezinhlotsheni zezentengiselwano.
Ukucatshangelwa Kokuzinza kanye Nezemvelo
Kwabakhi bezentengiselwano abaphishekela izitifiketi zezakhiwo eziluhlaza (i-LEED, i-BREEAM, noma i-DGNB), ukumbozwa kwe-WPC kunegalelo ezinhlotsheni eziningana zesikweletu:
- Okuqukethwe okuphinde kwasetshenziswa. Amabhodi e-WPC aqukethe i-fiber yokhuni engu-50-60% (evela kudoti wokhuni olusetshenzisiwe kanye nemikhiqizo engaphansi kwemishini yokusika izinkuni) kanye ne-HDPE esetshenzisiwe engu-30-35% (ipulasitiki esetshenziswe kabusha ngemuva komthengi). Leli phesenti lokuqukethwe okusetshenzisiwe lifanelekela i-LEED MR Credit: Ukudalulwa Komkhiqizo Wokwakha kanye Nokwenza Kahle — Ukuthola Izinto Ezingavuthiwe.
- Akukho zinkuni eziqinile zasezindaweni ezishisayo. Ukusebenzisa i-WPC esikhundleni sokufakwa kwe-hardwood cladding yasezindaweni ezishisayo (Ipe, Cumaru, Balau) kuqeda ukugawulwa kwamahlathi kanye nomthelela wezinto eziphilayo ohambisana nokuvunwa kwezinkuni zasezindaweni ezishisayo. Lokhu kuhambisana nezikweletu ze-BREEAM MAT 03 (Responsible Sourcing).
- Ukuphinda kusetshenziswe ekupheleni kokuphila.Ukumbozwa kwe-WPC kungagaywa futhi kukhishwe kabusha kube okusha Umkhiqizo we-Wpcs ekupheleni kokuphila — ngokungafani nokufakwa kwezinkuni okuphathwe ngezilondolozi, okumele kulahlwe njengemfucuza eyingozi ezindaweni eziningi.
Ngenxa yokuthi ukumbozwa kwe-WPC kwenziwa ngemifudlana yemfucuza (i-fiber yokhuni ephinde yasetshenziswa kanye nepulasitiki ephinde yasetshenziswa), ibhekana nezidingo zomnotho ojikelezayo eziya ngokuya zidingeka ezinhlotsheni zokuthengwa komphakathi zaseYurophu.
imibuzo ejwayelekile ukubuzwa
I-WPC co-extrusion cladding isebenza kanjani ezindaweni ezibandayo kakhulu njengeScandinavia?
I-WPC co-extrusion cladding isebenza kahle emakhazeni amakhulu ngoba i-polymer matrix ayibi brittle emazingeni okushisa angaphansi kuka-zero — izinga lokushisa lokushintsha kwengilazi le-HDPE binder licishe libe ngu--120°C. I-cladding yethu ihlolwe ukuthi i-freeze-thaw cycling ngokwe-EN 15534 (imijikelezo eyi-100 kusukela ku--20°C kuya ku-+20°C ngaphandle kokuqhekeka okubonakalayo, ukugoba, noma ukuhlukanisa). Isendlalelo se-cap sigcina ubuqotho baso nge-thermal cycling, okuyindlela eyinhloko yokwehluleka kwemikhiqizo ye-WPC yesizukulwane sokuqala ngaphandle kwe-co-extrusion. Abafaki emazweni aseNordic kufanele bagcine igebe lokunwebeka elingu-3-5mm emaphethelweni ebhodi ukuze bamukele ukunyakaza kokushisa (i-WPC inwebeka cishe ngo-1.5-2.0mm ngemitha ngayinye ene-swing yokushisa engu-30°C).
Ingabe ukumbozwa kwe-WPC kungapendwa noma kufakwe imibala ukuze kushintshe umbala ngemva kokufakwa?
Nakuba ukumbozwa kwe-WPC kungayamukela ngobuchwepheshe upende noma ibala, angikuncomi. Isendlalelo sesivalo se-co-extrusion senzelwe ngqo ukumelana nokunamathela kokumbozwa kobuso - yilokhu okwenza kungabi nokugcinwa kahle kwasekuqaleni. Ukufaka upende noma ibala ngeke kuhlangane ngokuthembekile ebusweni besivalo futhi kuzoqhekeka phakathi neminyaka eyi-1-2. Uma udinga umbala othize, oda ukumbozwa ngalowo mbala ngesikhathi sokukhiqiza. Uhla lwethu lwemibala olujwayelekile luhlanganisa amaphethini ayi-8 okhuni (i-oki, i-walnut, i-teak, i-cedar, i-charcoal, i-slate grey, izinkuni ezigugile, kanye ne-whitewash), futhi imibala yangokwezifiso iyatholakala kuma-oda angaphezu kwamamitha-skwele ayi-5,000.
Iyini isilinganiso somlilo se-WPC ejwayelekile ngaphandle kwezithasiselo ezivimbela umlilo?
I-WPC ejwayelekile engenazo izithasiselo ezivimbela umlilo ngokuvamile ifinyelela isilinganiso se-Euroclass D-s1, d0 noma i-C-s1, d0 ngaphansi kwe-EN 13501-1, esifana nezinkuni ezithambile ezingalashwanga. Ezakhiweni zezentengiselwano ezidinga izilinganiso zomlilo eziphezulu (Isigaba B noma ngaphezulu), chaza ifomula yethu evimbela umlilo efinyelela i-B-s1, d0. ENyakatho Melika, i-WPC ejwayelekile ivame ukufeza i-ASTM E84 Isigaba A (inkomba yokusabalala komlilo 0-25). Njalo qinisekisa umbiko wokuhlolwa komlilo womkhiqizo othize nombala owu-odayo, njengoba ama-pigment kanye nokwakheka kwengqimba yesivalo kungathinta ukusebenza komlilo.
Ukumbozwa kwe-WPC kusingatha kanjani ukukhula kwezinto eziphilayo njengokukhunta kanye nolwelwe?
Ukumbozwa kwe-WPC co-extrusion kumelana kakhulu nokukhula kwezinto eziphilayo ngoba ungqimba lwesivalo se-polymer alunikezi umthombo wokudla we-organic we-mold noma i-algae spores. Kodwa-ke, ezindaweni ezinomthunzi, ezimanzi unomphela (izindonga ezibheke enyakatho ezindaweni ezinomswakama), i-biofilm engaphezulu ingakhula kunoma iyiphi into yangaphandle. Uma lokhu kwenzeka, ukuhlanza ngesisombululo sensipho esithambile kanye nebhulashi elithambile kwanele - ngokungafani nokumbozwa kwezinkuni, okungadinga ukwelashwa ngamakhemikhali kanye nokusikwa kabusha ukuze kususwe isikhunta esifakiwe. Izithasiselo ze-fungicide ku-WPC core compound zinikeza ungqimba olwengeziwe lokuvikela ekuboleni kwesikhunta uma umswakama ungena emphethweni noma ekuklwebheni.
Yisiphi isiqinisekiso uYida asihlinzekayo nge-WPC co-extrusion cladding?
Sinikeza iwaranti elinganiselwe yeminyaka eyi-15 ehlanganisa ubuqotho besakhiwo, ukufiphala kombala (ngaphansi kwamayunithi ama-5 e-Delta E ngaphakathi kwesikhathi sewaranti), kanye nokwehlukaniswa kwesendlalelo se-co-extrusion cap. Iwaranti isebenza uma i-cladding ifakiwe ngokwesiqondiso sethu sokufaka (kufaka phakathi umoya ofanele, ukubopha, kanye nemininingwane yegebe lokunwetshwa) futhi ayimbozi umonakalo obangelwa ukusetshenziswa okungafanele, umthelela, noma ukuguqulwa okungagunyaziwe. Siphinde sinikeze izinketho zewaranti ezinde zeminyaka engama-25 zamaphrojekthi angaphezu kwamamitha-skwele ayi-10,000. Imibhalo ephelele yewaranti, kufaka phakathi imibiko yokuhlola ngayinye I-ICC-ES kanye ne-EN 15534, kunikezwa ngokuthunyelwa ngakunye.
