Kungani Izimo Zezulu Ezishisayo Zishintsha I-Expansion Gap Calculus
Ukwanda kokushisa kuyimpahla ebonakalayo, akuyona inketho yokuklama — kodwa indawo ezungezile inquma ukuthi kubaluleke kangakanani. Njalo izingodo ezihlanganisiwe umkhiqizo uyanyakaza lapho izinga lokushisa lawo lishintsha. i-coefficient yokwanda okuqondile Kwezitezi ze-WPC ezijwayelekile zisukela ku-3.0 × 10⁻⁵ kuya ku-5.5 × 10⁻⁵ nge-°C, kuye ngesilinganiso se-wood-fiber-to-polymer, uhlobo lwe-polymer (i-HDPE vs. PP), nokuthi ibhodi livaliwe noma alivaliwe. Ibhodi le-WPC elingu-3.6m elishiswe ngo-20°C ngaphezu kwezinga lokushisa lokufakwa kwalo lizokhula phakathi kuka-2.2mm no-4.0mm ubude balo — ukunyakaza okuthi, uma kungavunyelwe, kudale ukucindezeleka okucindezelayo ezindaweni zokubopha futhi ekugcineni kubangele ukugoba, ukugoba, noma ukudonswa kwezikulufo.
Ezimweni zezulu ezifudumele, lokhu kuhamba kwenzeka kancane kancane ngokwemijikelezo yezinkathi. Abafaki babeka izikhala entwasahlobo bese ibhodi lifinyelela ekukhuleni okuphezulu ehlobo, bese lincipha futhi ekwindla. Ku- izimo zezulu ezishisayo, umjikelezo ofanayo wokukhulisa nokukhuhlana kwenzeka nsuku zonke. Idekhi eSingapore, eBangkok, noma eJakarta ingase ibhekane nokushintshashintsha kwezinga lokushisa lobuso okungu-20-30°C phakathi kwasekuseni naphakathi kwantambama — nsuku zonke, unyaka wonke. Amabhodi awalokothi aphumule ngokulinganayo isikhathi esingaphezu kwamahora ambalwa, okusho ukuthi izikhonkwane, ama-clip, kanye nokuxhumeka kwama-joist kuhlangabezana nokujikeleza kokukhathala okungabonwa amadekhi asezindaweni ezipholile.
Ukubuka kweqembu lethu lokuthumela kwamanye amazwe kulo lonke elaseNingizimu-mpumalanga ye-Asia (okumboza amaphrojekthi angu-47 edekhi lezentengiselwano nelezindawo zokuhlala afakwe phakathi kuka-2020 no-2025 eSingapore, eMalaysia, eThailand, eVietnam nase-Indonesia) kubonisa iphethini ehambisanayo: Amadekhi afakwe ngezibonelelo zegebe ezithile zasezindaweni ezishisayo azinazo izikhalazo zokubuyela emuva zokugoba noma ukugoba, kuyilapho amadekhi afakwe anegebe elijwayelekile lesifunda esinomoya opholile (ngokuvamile elichazwe umehluko we-10-15°C) eba nokucindezeleka okubonakalayo kwamalunga zingakapheli izinyanga ezingu-12-18. Imodi yokuhluleka ayiyona into ephawulekayo — iqala ngokugoqana okuncane emajoyintini ezinqe, iqhubekela phambili ekuguqukeni kwe-clip, futhi ekugcineni ikhiqize ukufuduka kwebhodi okubonakalayo okubangela ukubizwa kabusha kwabakhi kanye nezimangalo zewaranti yomthengisi.
| Ipharamitha | Isimo Sezulu Esifudumele (isib., eLondon, eBerlin) | Isimo Sezulu Esishisayo (isb., Singapore, Jakarta) |
|---|---|---|
| Ububanzi bokushisa bonyaka | -5°C kuya ku-35°C (ubude obungu-40°C) | 23°C kuya ku-38°C (ubude buka-15°C) |
| Ukushwibeka kwansuku zonke (indawo yokubeka ideski) | 8-12°C (umjikelezo wesizini) | 15-25°C (umjikelezo wansuku zonke) |

Qaphela: Idatha yokushisa kobuso ilinganiswa nge-thermometer ye-infrared kumabhodi e-WPC anombala omnyama ekukhanyeni kwelanga okuqondile kwe-tropical emini yelanga, ukuphakama okungaphansi kwama-50m ngaphezu kolwandle. Amanani ayahlukahluka ±8% kuye ngombala webhodi, ukuma, kanye namaphethini omthunzi wendawo.
Ithebula elingenhla lembula iqiniso eliphikisanayo: izimo zezulu zasezindaweni ezishisayo, naphezu kokuba nezinga lokushisa lonyaka elincane, zibeka ukucindezeleka okukhulu kokukhathala ezifakeni zedekhi ngoba ukujikeleza kokushisa kwansuku zonke kunamandla kakhulu futhi akukaze kume. Idekhi eLondon ikhula kanye ngehlobo futhi incipha kanye ebusika — imijikelezo emikhulu engu-12 ngonyaka. Idekhi eSingapore ikhula njalo ntambama futhi incipha njalo ebusuku — imijikelezo engu-365 ngonyaka. Ukukhathala kwe-fastener okuhlanganisiwe esikhathini sewaranti yeminyaka eyi-10 kuphakeme ngama-30× ezindaweni ezishisayo, yingakho ukucaciswa kwegebe kanye nokukhethwa kwe-fastener kuba yinto ebalulekile ekucacisweni kunokuba kube yinto evamile ukufakwa.
I-Co-Extruded vs. Classic WPC: Yimuphi Uphrofayili Ophatha Kangcono Ukuhamba Kwezindawo Ezishisayo?
Akuwona wonke amabhodi e-WPC ashintsha inani elifanayo, futhi inqubo yokukhiqiza iyona ehlukanisayo. Amaphrofayili amabili amakhulu e-WPC decking emakethe yomhlaba wonke — akudala (angavaliwe) kanye nahlanganisiwe (avalwe) — aziphatha ngendlela ehlukile ngaphansi kokucindezeleka kokushisa kwezindawo ezishisayo ngoba ukwakheka kwawo kwezinto kuphatha i-UV kanye nomswakama ngendlela ehlukile.
Idekhi ye-WPC yakudala, njenge-YDWPC YD150SH25, YD150RH30, YD150S20, YD150H30, YD150H25, YD142S10, YD140SH25, YD140S25, kanye ne-YD140RH25, iyinhlanganisela ekhishwe ye-fiber yokhuni kanye ne-thermoplastic (ngokuvamile i-HDPE) engenalo ungqimba lwangaphandle oluvikelayo. Okuqukethwe kwe-fiber yokhuni - ngokuvamile okungu-50-60% ngesisindo - kunikeza ukuqina kwesakhiwo kanye nomuzwa wemvelo ofana nokhuni, kodwa futhi kubamba imisebe ye-UV ngqo ebusweni bebhodi. Ezimweni ze-UV ezishisayo (inkomba ye-UV 10-12+ unyaka wonke), imicu yokhuni engaphezulu yonakala ngokushesha kune-polymer matrix, okudala ubulukhuni obuncane obusheshisa ukumuncwa komswakama kanye nokucindezeleka kokujikeleza kokushisa.
I-WPC decking ehlanganisiwe isebenzisa ungqimba lwesivalo se-polymer phezu kwengqikithi ehlanganisiwe ngenqubo yokukhipha ngesikhathi esisodwa - ingqikithi nesivalo kuhlanganiswa ngendlela eyodwa, hhayi ukunamathela ngemva kwalokho. Umugqa we-YDWPC co-extrusion ukhiqiza amaphrofayili e-YD140RH23 (ububanzi obungu-140mm × ukuphakama okungu-23mm) kanye ne-YD140S23 anegobolondo le-polymer elihlanganisiwe elingu-360° elihlanganisa umongo kuzo zonke ubuso obune. Lolu ngqimba lwe-cap — ngokuvamile oluyi-HDPE noma i-ASA (acrylonitrile styrene acrylate) olushintshiwe — lusebenza imisebenzi emithathu ezimweni ezishisayo:
- Ukuvikelwa kwe-UV: Isivalo simunca futhi sikhanyise i-UV ngaphambi kokuba sifinyelele enkabeni ye-wood-fiber, kunciphisa ukuwohloka kobuso kanye nokuqhekeka okuncane okuhambisana nakho okusheshisa ukunyakaza kokushisa. Ngokusho kokuhlolwa kwezinto okubhekiselwe kuzo ku I-EN 15534-4, amabhodi akhishwe ndawonye agcina u-85-90% wamandla awo okuqala okuguquguquka ngemva kwamahora angu-2,000 okuvezwa kwe-UV okusheshayo, uma kuqhathaniswa no-65-75% wamaphrofayili akudala angavaliwe.
- Isithiyo somswakama: Izinga lokumuncwa kwamanzi le-polymer cap lingaphansi kuka-0.5% ngesisindo (ngokucwiliswa kwamahora angama-24), uma kuqhathaniswa no-2-4% we-WPC cores engavaliwe. Ezindaweni ezishisayo ezinomswakama ongu-80-90%, lo mehluko uhumusha ekushintsheni okuncane kakhulu kobukhulu be-hygroscopic - i-vector eyodwa yokunyakaza encishisiwe ukuze imininingwane yegebe imuncwe.
- Ubulukhuni bomphezulu kanye nokumelana nokushelela: Ukwakheka kwe-polymer yesendlalelo sesivalo kungaklanywa ukuze kube nokuqina okuphezulu kobuso (i-Shore D 65-75) kune-core composite (i-Shore D 55-60), okuthuthukisa ukumelana nokushelela — incazelo ebalulekile yokuphepha ye-poolside kanye ne-marine decking ezindaweni zokuphumula zasezindaweni ezishisayo kanye namaphrojekthi ezentengiselwano lapho izimo ezimanzi zihlala khona.
Kwabasabalalisi abahlola i-WPC ehlanganisiwe uma kuqhathaniswa ne-WPC yakudala yezimakethe zasezindaweni ezishisayo, Inzuzo yokucaciswa kwe-co-extrusion akuyona nje ukumelana ne-UV - kungumphumela ohlanganisiwe wokuwohloka okuphansi kwe-UV, ukumuncwa komswakama okuphansi, kanye nokwanda okuphansi kokushisa, konke okunciphisa ubukhulu bokunyakaza okumele kuhlangatshezwe yi-gear specification. Nakuba amaphrofayili e-WPC akudala ehlala eyindlela engabizi kakhulu yokufaka ezindaweni ezishisayo ezimboziwe noma ezifakwe umthunzi (amaveranda, ama-pergola, izindlela zokuhamba ezimboziwe), amadekhi ashisayo avulekile — eceleni kwechibi, ophahleni, ibhodi lokuhamba, i-marina — azuza kakhulu ekuvikelweni kwesivalo esihlanganisiwe.
| Imininingwane | I-Co-Extrusion (YD140RH23 / YD140S23) | Okwakudala (amamodeli angu-9, ububanzi obungu-140-150mm) |
|---|---|---|
| Ububanzi bebhodi | 140mm | 140-150mm |
| Ukuphakama kwebhodi | 23mm | 10-30mm (kuncike kumodeli) |
| Isendlalelo sesivalo | Igobolondo le-polymer elihlanganisiwe elingu-360° | Akukho (okungavaliwe) |

| Iwaranti | Iminyaka eyi-15-25 | Iminyaka eyi-10-15 |
| Ukusetshenziswa okunconyiwe kwe-tropical | Ukuchayeka okuvulekile: eceleni kwechibi, ophahleni, ibhodi lokuhamba ngezinyawo, i-marina | Imboziwe/efakwe umthunzi: iveranda, i-pergola, indlela yokuhamba |
| Izakhiwo ezibalulekile | Ayingeni manzi, ayingeni umswakama, ayingenwa yisikhunta, ayingenwa yizinambuzane, ayiqhekeki, ayisheleli, ayingenwa yizigqwala | Angangenwa manzi, amelana nomswakama, amelana nokukhunta, amelana nezinambuzane, amelana nokugqwala, akugcinwa kahle |
Abasabalalisi abakhonza izimakethe zasezindaweni ezishisayo kufanele baqaphele ukuthi ububanzi obuncane obungu-140mm bamaphrofayili e-co-extrusion (uma kuqhathaniswa no-150mm kumamodeli amaningi akudala) kusho amamitha ambalwa aqondile egebe lokunwetshwa ngemitha yesikwele yedekhi efakiwe - ukusebenza kahle kokufakwa okulinganiselwe lapho kucashunwa amaphrojekthi amakhulu ezentengiselwano.
Incazelo Yesikhala Sokunwetshwa: Lokho Abasabalalisi Okufanele Bakudinge Kubakhiqizi
Ukucaciswa kwegebe lokunwetshwa akuyona inkambu efanelana nenombolo eyodwa - idinga isincomo esibhalwe phansi, esisekelwa ukuhlolwa esivela kumkhiqizi esibheka ubude bebhodi, ukuma, umbala, kanye nezimo zezulu zendawo. Abasabalalisi abamukela ulimi olujwayelekile oluthi "shiya isikhala esincane" eziqondisweni zokufaka bazibekela izingxabano zewaranti kanye nokubizwa kabusha kwabakhi. Nasi uhlaka lwemininingwane olunconywa yithimba lethu kumaphrojekthi e-WPC asezindaweni ezishisayo.
Isinyathelo 1: Funa inani le-coefficient yokwandisa ukushisa okuqondile (i-CLTE) elishicilelwe ngumkhiqizi, elihlolwe ngokwesilinganiso ngasinye I-ASTM D7032 noma NGO-15534. Lena inombolo eyisisekelo — ikutshela kahle ukuthi ibhodi lizohamba malini ngezinga lokushintsha kwezinga lokushisa, ngeyunithi yobude. Umenzi ongakwazi ukukhiqiza inani le-CLTE elihlolwe ngezinga eliqashelwayo akacacisi; bayaqagela. Ngokufaka i-WPC decking, amanani e-CLTE ngokuvamile asukela ku-3.0 × 10⁻⁵ /°C (okuqukethwe okuphezulu kwe-wood-fiber, okuhlanganisiwe) kuya ku-5.5 × 10⁻⁵ /°C (okuqukethwe okuphezulu kwe-polymer, okungavaliwe). Umehluko phakathi kwala manani amabili, asetshenziswa ebhodini elingu-3.6m phezu kokushintsha kwezinga lokushisa elingu-30°C, umehluko phakathi kokunyakaza okungu-3.2mm no-5.9mm — cishe kabili.
Isinyathelo sesi-2: Bala ibanga lokunyakaza elilindelekile lobude bebhodi elithile, umbala, kanye nendawo yesimo sezulu. Amabhodi amnyama amunca imisebe yelanga eyengeziwe futhi afinyelele amazinga okushisa aphezulu omhlaba — ibhodi le-walnut WPC elimnyama elangeni eliqondile elishisayo lingafinyelela ku-70-75°C ebusweni, kuyilapho ibhodi elifanayo elinombala ompunga okhanyayo lingafinyelela ku-55-60°C. Umehluko wokushisa kobuso ongu-15°C uhumusha ukunyakaza kokushisa okucishe kube ngu-40% kwebhodi elimnyama. Kwibhodi elimnyama elinombala omnyama elingu-3.6m eSingapore (izinga lokushisa elijwayelekile lokufakwa lingu-30°C, izinga lokushisa lobuso eliphakeme lingu-70°C, i-CLTE 3.5 × 10⁻⁵ /°C): ukunyakaza okulindelekile kobude obude = 3,600mm × 40°C × 3.5 × 10⁻⁵ = 5.04mm. Lena inombolo okumele imininingwane yesikhala iyimunce — futhi kufanele ibhalwe phansi kumhlahlandlela wokufaka womenzi bese kubonakala indlela ethile yokubala.
Isinyathelo 3: Qinisekisa ukuthi umenzi uhlinzeka ngemininingwane yesikhala sokugcina (i-butt joint) kanye nesikhala esiseceleni, hhayi nje esisodwa noma esinye. Ukwehluleka okuningi kokufakwa kwe-WPC ezimakethe zasezindaweni ezishisayo kuhilela izikhala zokugcina — amalunga lapho amabhodi amabili ahlangana khona ngobude bawo. Izikhala eziseceleni (phakathi kwamabhodi ahambisanayo ahamba ohlangothini olufanayo) nazo ziyahamba, kodwa uhlelo olujwayelekile lwe-hidden-clip lumunca okunye kwalokhu kunyakaza ngokuguquguquka kwe-clip. Izikhala zokugcina azinawo ama-buffer anjalo — kumele zicaciswe futhi zigcinwe ngokunembile. Isincomo sethimba lethu ukuqinisekisa ukuthi imininingwane yesikhala sokugcina ivezwa njengobubanzi (ubuncane kuya kobukhulu) ngokusekelwe kubude bebhodi kanye nomehluko wokushisa wendawo, hhayi njengenombolo eyodwa ehleliwe.
Isinyathelo 4: Qinisekisa ukuthi imininingwane ichaza izinga lokushisa eliphelele lokufakwa — hhayi izinga lokushisa lomoya elizungezile kuphela. Iphutha elivamile lokucacisa liwukusekela ukubalwa kwesikhala ekushiseni komoya ngesikhathi sokufakwa (isb., 28°C ekuseni eBangkok). Inombolo efanele izinga lokushisa lebhodi lapho kufakwa, okungaba ngaphezulu kuka-10-15°C elangeni eliqondile elishisayo kunomoya ozungezile. Uma umfakisi ebeka izikhala ngokusekelwe ekushiseni kokufakwa okungu-28°C kodwa empeleni ibhodi lingu-40°C ebusweni, ibhodi lizoncipha lapho liphola ngalobo busuku - lishiya izikhala zibanzi kunalokho okuchaziwe. Abakhiqizi kufanele beluleke abafaki ukuthi bavumelanise amabhodi nokushisa okuzungezile emthunzini ngaphambi kokulinganisa nokubeka izikhala, futhi babhale phansi le mfuneko kumhlahlandlela wabo wokufaka.
Nakuba imikhiqizo ye-YDWPC yenzelwe ukuzinza kobukhulu, izidingo ezithile zegebe lokunwebeka zincike ezimweni zesimo sezulu sendawo, ukuqondiswa kokufakwa, kanye nobude bebhodi. Bheka umhlahlandlela wokufakwa komkhiqizi ukuze uthole izincomo zephrojekthi ethile. Abasabalalisi bangacela amashidi edatha okufaka aqondene nephrojekthi ye-YDWPC ngokuxhumana nethimba lethu lokuthumela ngaphandle, okuhlanganisa imodeli yebhodi, ubude bebhodi, umbala webhodi, indawo yokufaka, kanye nokuqondiswa kokufaka (okufanayo noma okuqondile ku-axis ende yesakhiwo).
Izinto Okumelwe Uzicabangele Nge-Fastener kanye Ne-Subframe Yama-Tropical WPC Decks
Izikhala zodwa azixazululi ukwanda kwezindawo ezishisayo — uhlelo lwe-fastener kanye ne-subframe kumele kuhambisane nokunyakaza ngaphandle kokukuphikisa. Igebe lokunwebeka elichazwe kahle alisebenzi uma i-fastener ibopha ibhodi ngokuqinile kangangokuthi ayikwazi ukushelela. Izincomo zeqembu lethu zemininingwane yokubopha i-WPC yasezindaweni ezishisayo yilezi ezilandelayo:
- Izinhlelo zokunamathisela ezifihliwe phezu kokukrufulula ubuso. Iziqeshana ezifihliwe zivumela ibhodi ukuthi lishelele ngobude eceleni kwe-clip rail ngesikhathi sokwanda nokuncipha kokushisa. Ukuskiya ubuso — ukushayela izikulufu ebusweni bebhodi zingene esibayeni — kudala iphuzu eliqinile elimelana nokunyakaza futhi lidale ukugxila kokucindezeleka emgodini wesikulufu. Ekufakweni kwezindawo ezishisayo ngokujikeleza kokushisa kwansuku zonke, iziqeshana ezifihliwe zinciphisa kakhulu ingozi yokudonswa kwezikulufu kanye nokuqhekeka kwebhodi ezindaweni zokubopha.
- Izibambo zensimbi engagqwali noma zensimbi yekhabhoni ezimboziwe. Umswakama wasezindaweni ezishisayo (70-90% RH unyaka wonke) usheshisa ukugqwala kwezinamathiseli zensimbi yekhabhoni ezingavikelekile. Izinamathiseli ezigqwalayo zanda ngobuningi (ukugqwala), okuqhekeza ibhodi le-WPC elizungeze umgodi wesinamathiseli. Cacisa izikulufo zensimbi engagqwali ze-A2 (304) noma ze-A4 (316) zamaphrojekthi asezindaweni ezishisayo zasolwandle nasogwini, noma insimbi yekhabhoni ehlanganiswe ne-Geomet® yamaphrojekthi angaphakathi nezwe. Ukugqwala kwe-fastener kuyindleko efihliwe ehamba phambili ekufakweni kwe-WPC ezindaweni ezishisayo — akuveli esilinganisweni sokuqala kodwa kuqhuba izimangalo zewaranti eminyakeni engu-3-5 ngemva kokufakwa.
- Izingodo ezilungisiwe noma ezingaphansi kwe-aluminium. Ama-joint ezinkuni angalungiswanga emswakama oshisayo ayabola zingakapheli iminyaka emi-2-3, alahlekelwe ukubamba kwawo kuma-fasteners futhi avumele idekhi ukuthi ishintshe ngendlela engalindelekile. Cacisa ukhuni oluphathwe yi-CCA- noma i-ACQ (H3.2 noma ngaphezulu nge ukulondolozwa kwezinkuni amazinga) noma amaphrofayili e-aluminium joist okuphila isikhathi eside kwe-subframe engaboli. Ama-subframe e-aluminium nawo asusa umphumela wokuvimba umswakama wokhuni, okwenza kube lula ukubalwa kwegebe lokunwebeka ngokususa okuguquguqukayo ku-equation.
Idekhi ye-WPC yesimo sezulu esishisayo iyibhodi, igebe, i-fastener, kanye nohlaka olungaphansi - futhi ukucacisa noma iyiphi into eyodwa ngokuyihlukanisa kukhiqiza ukuzethemba okungamanga. Abasabalalisi abahlinzeka ngazo zonke izingxenye ezine njengohlelo oluhambisanayo baletha imiphumela engcono yephrojekthi kanye nezimangalo zewaranti ezimbalwa kunalabo abathengisa amabhodi kuphela futhi bashiyela ukukhethwa kwe-fastener kanye ne-subframe konkontileka.
Ukuthobela Imithetho Nokuqinisekiswa: Lokho Abanikazi Bephrojekthi YaseTropical Okufanele Bakufune
Ikhodi yokwakha Ukuthobela imithetho ye-WPC decking ezimakethe zasezindaweni ezishisayo kuyahlukahluka kuye ngezwe, kodwa izinhlaka ezimbili zokuhlola eziqashelwa emhlabeni wonke — NGO-15534 (yaseYurophu) kanye I-ASTM D7032 (eNyakatho Melika) — nikeza isisekelo semininingwane esisetshenziswa noma esisetshenziswa amakhodi amaningi kazwelonke. Abasabalalisi abakhonza izimakethe zokuthumela kwamanye amazwe zasezindaweni ezishisayo kufanele baqinisekise ukuthi imikhiqizo yabahlinzeki babo be-WPC ihlolwe okungenani ngeyodwa yalezi zindinganiso, ngemibiko yokuhlolwa evela emalabhorethri agunyaziwe.
Ngokuphathelene ne-WPC decking eyenzelwe amaphrojekthi asezindaweni ezishisayo, izigaba zokuhlola ezibaluleke kakhulu yilezi:
- EN 15534-1 / ASTM D7032 — Amandla kanye ne-modulus yokuguquguquka: Iqinisekisa ukuthi ibhodi lingasekela imithwalo yokuklama (ngokuvamile umthwalo wamaphuzu angu-2.0 kN wezindlu zokuhlala, 4.0 kN wezohwebo) ngaphandle kokuguquka okuhlala njalo. Ezindaweni ezishisayo lapho amabhodi ehlangabezana nokujikeleza kokushisa kwansuku zonke, izakhiwo ze-flexural kumele zihlolwe ekushiseni okuphezulu (40°C noma ngaphezulu) ukuze zibonise izimo zangempela.
- EN 15534-4 — Ukusheshisa kwesimo sezulu: Ukuvezwa kwe-UV, ukufuthwa ngamanzi, kanye nokujikeleza kokuncibilikisa (noma ukujikeleza komswakama okulingana nezindawo ezishisayo). Lokhu kuhlolwa kulinganisa ngqo ukumelana kwebhodi ekuwohlokeni komphezulu okuqhuba izinguquko zokuziphatha zokukhula kwesikhathi eside.
- EN 15534-1 — Ukuqina kobukhulu: Ilinganisa ubude nobubanzi bebhodi ngemva kokucwiliswa emanzini kanye nemijikelezo yokomisa. Lena yindlela eseduze kakhulu yokwelapha ukuziphatha kokukhula kwezindawo ezishisayo emhlabeni wangempela.
- Ukumelana nokushelela (EN 13845 noma BS 7976-2): Kubalulekile kakhulu emazingeni okubhukuda, olwandle, kanye nakwezentengiselwano lapho izimo ezimanzi zihlala zinjalo. Amabhodi ahlanganisiwe anezimbobo ezimbozwe ngombala (njengokuqedwa kwe-YDWPC YD140RH23's wood-grain) ngokuvamile afinyelela i-PTV 45-65 (Inani Lokuhlola le-Pendulum) ezimweni ezimanzi — ngaphezu kwe-UK HSE okungenani engu-36 "yekhono eliphansi lokushelela."
Imikhiqizo ye-YDWPC co-extrusion kanye ne-classic decking yenziwa ngaphansi I-ISO 9001 ukuphathwa kwekhwalithi futhi kuhlolwe ngezindinganiso zomhlaba wonke ezifanele. Ukumaka i-CE kanye nemibiko yokuhlola iyatholakala kumaphrojekthi okuthumela kwamanye amazwe uma iceliwe.

I-YDWPC inikeza wonke amadokhumenti angenhla encazelo yemigqa yethu yokuxhumanisa kanye neyakudala — xhumana nethimba lethu lokuthumela ngaphandle ngemininingwane yephrojekthi yakho ukuze uthole iphakheji ephelele yencazelo.
imibuzo ejwayelekile ukubuzwa
Umbuzo 1. Ingakanani i-WPC decking eyanda ezindaweni ezishisayo?
I-WPC decking ezindaweni ezishisayo ivame ukwanda ngo-2-6mm ngobude bebhodi obungu-3.6m ngesikhathi sokujikeleza kokushisa kwansuku zonke, kuye ngombala webhodi, ukwakheka kwezinto, kanye nokushisa kobuso. Ukubalwa kokunwetshwa kuncike ku-coefficient yebhodi yokwanda kokushisa okuqondile (i-CLTE), umehluko wokushisa phakathi kokufakwa kanye nokushisa okuphezulu kobuso, kanye nobude bebhodi. Isibonelo, ibhodi elihlanganisiwe elinombala omnyama elingu-3.6m elifakwe ku-30°C futhi lifinyelele izinga lokushisa lobuso elingu-65°C (umehluko ongu-35°C) eline-CLTE engu-3.5 × 10⁻⁵ /°C lizonwebeka cishe ngo-4.4mm ubude balo. Amabhodi anombala okhanyayo angabona ukwanda okungaphansi ngo-20-30% ngenxa yokumuncwa kwelanga okuphansi. I-YDWPC ishicilela amanani e-CLTE awo wonke amaphrofayili e-decking - xhumana nethimba lethu lokuthumela ngaphandle ukuze uthole ukwesekwa kokubala okuqondene nephrojekthi ethile.
Umbuzo 2. Ingabe amabhodi e-WPC ahlanganisiwe angcono kune-WPC yakudala yokufakwa ezindaweni ezishisayo?
Ukuze kufakwe izindawo ezishisayo ezivulelekile (eceleni kwechibi, ophahleni, ebhodini, ebhishi), amabhodi e-WPC ahlanganisiwe anikeza ukusebenza okungcono kakhulu kwesikhathi eside ngenxa yesendlalelo sawo se-polymer esivikela i-UV, esinciphisa ukuwohloka komphezulu, ukumuncwa komswakama, kanye nobukhulu bokukhula kokushisa. Isivalo esikhishwe ngokuhlanganyela esingu-360° kumaphrofayili e-YDWPC YD140RH23 kanye ne-YD140S23 sinikeza ukumuncwa kwamanzi okungu-
Umbuzo 3. Uyini umehluko phakathi kwe-co-extruded kanye ne-classic WPC decking?
I-WPC decking ehlanganisiwe inongqimba lwesivalo se-polymer esivikelayo esihlanganiswe phezu kwengqikithi ehlanganisiwe ngesikhathi sokukhiqiza, kuyilapho i-WPC decking yakudala iwukukhushulwa kwe-fiber yokhuni kanye ne-thermoplastic okungavaliwe. Isendlalelo sesivalo — sisetshenziswa ngokusebenzisa i-extrusion ngesikhathi esisodwa (ukuxhumanisa) inqubo — ivikela umongo emisebeni ye-UV, ukungena komswakama, kanye nokupenda kobuso. Amaphrofayili e-WPC akudala (njenge-YDWPC YD150SH25, YD150RH30, namanye amamodeli ebangeni lobubanzi obungu-140-150mm) ahlinzeka ngokusebenza okuhle kakhulu kwesakhiwo kokufakwa okumboziwe futhi atholakala ebangeni elibanzi lobukhulu bephrofayili (ukuphakama okungu-10-30mm). Amaphrofayili ahlanganisiwe (YDWPC YD140RH23, YD140S23) alungiselelwe ukusetshenziswa kwangaphandle okuveziwe lapho ukumelana ne-UV, ukusebenza kokuvimbela umswakama, kanye nokugcinwa kombala isikhathi eside kubaluleke kakhulu.
Umbuzo 4. Ingabe amadekhi e-WPC adinga izikhonkwane ezikhethekile ezindaweni ezishisayo?
Yebo — umswakama wasezindaweni ezishisayo usheshisa ukugqwala kwezithako, futhi ukujikeleza kokushisa kwansuku zonke kudinga izinhlelo zezithako ezivumela ukunyakaza kwebhodi ngaphandle kokukuphikisa. Cacisa iziqeshana ezifihliwe zensimbi engagqwali ze-A2 (304) noma ze-A4 (316) zamaphrojekthi asezindaweni ezishisayo zasolwandle nasogwini, noma insimbi yekhabhoni embozwe ngokugqwala okuphezulu kwamaphrojekthi angaphakathi nezwe. Izinhlelo zeziqeshana ezifihliwe zithandwa kakhulu kunokufaka ubuso ezindlini ezishisayo ngoba zivumela ibhodi ukuthi lishelele isikhathi eside ngesikhathi sokwanda nokuncipha kokushisa. Izifakelo ezigqwala zanda ngobuningi (ukugqwala), okuqhekeka ibhodi le-WPC elizungeze umgodi wezifakelo — imodi yokwehluleka evame ukuvela eminyakeni engu-3-5 ngemuva kokufakwa futhi ivame ukungachazwa kahle ngekhwalithi yebhodi kunokukhethwa kwezifakelo. I-YDWPC itusa izinhlelo ezithile zezifakelo zephrofayili ngayinye yedekhi — xhumana nethimba lethu lokuthumela ngaphandle ukuze uthole imininingwane yokuhambisana.
Umbuzo 5. Yiziphi izitifiketi okufanele ngizibheke lapho ngithola i-WPC decking yamaphrojekthi okuthumela kwamanye amazwe asezindaweni ezishisayo?
Izinhlaka ezimbili zokuhlola ze-WPC eziqashelwa emhlabeni wonke yilezi NGO-15534 (Indinganiso yaseYurophu ehlanganisa izakhiwo zemishini, ukuzinza kobukhulu, kanye nesimo sezulu) kanye I-ASTM D7032 (Indinganiso yaseNyakatho Melika yokuhlola ukusebenza kwezinkuni ezihlanganisiwe). Kumaphrojekthi asezindaweni ezishisayo, cela imibiko yokuhlola ehlanganisa: (1) amandla okuguquguquka ekushiseni okuphezulu (40°C+), (2) ukusheshisa kwe-UV ngokwe-EN 15534-4, (3) ukumuncwa kwamanzi ngokwe-EN 15534-1, kanye (4) ukumelana nokushelela ngokwe-EN 13845 noma i-BS 7976-2. Ngaphezu kwalokho, qinisekisa ukuthi umenzi usebenza ngaphansi I-ISO 9001 ukuphathwa kwekhwalithi — lokhu akuqinisekisi ukusebenza komkhiqizo, kodwa kuqinisekisa ukuthi izinqubo zokukhiqiza zibhaliwe, ziyahlolwa, futhi ziyahambisana. Imikhiqizo ye-YDWPC ikhiqizwa ngaphansi kwe-ISO 9001 futhi ihlolwe ngokwezindinganiso zomhlaba wonke ezifanele. Ukumaka i-CE kanye nemibiko yokuhlolwa kwelebhu egunyaziwe iyatholakala kumaphrojekthi okuthumela ngaphandle uma iceliwe.
Umbuzo 6. Ingabe i-WPC decking ingafakwa ngqo kukhonkolo ezindaweni ezishisayo?
I-WPC decking ingafakwa ezisekelweni zekhonkrithi ezindaweni ezishisayo kusetshenziswa izinhlelo ze-pedestal noma ze-batten, kodwa ukufakwa ngqo kwendawo ngaphandle kokususwa kwepayipi lokukhipha amanzi akukhuthazwa. Imvula yasezindaweni ezishisayo (ngokuvamile engu-1,500-3,000mm ngonyaka) idala umswakama omi ngaphansi kwedekhi okudingeka ukuthi ikhiphe amanzi ngokukhululeka. Uhlelo oluphakanyisiwe lwesisekelo noma lwebhathini ludala igebe lomoya elingu-25-50mm phakathi kwamabhodi e-WPC kanye nesisekelo sekhonkrithi, okuvumela ukukhishwa kwamanzi kanye nokugeleza komoya okunciphisa ukwakheka komswakama kanye nengozi yokubola. Idekhi Umkhuba omuhle wokwakha ezindaweni ezishisayo udinga futhi ukuthambekela okungenani okungu-1-2% ku-substrate yekhonkrithi ukuze kuqondiswe amanzi ezindaweni zokukhipha amanzi. Ekufakweni kophahla lapho i-concrete slab isebenza khona njenge-membrane engangeni manzi, izinhlelo ze-pedestal zisabalalisa umthwalo ngokulinganayo futhi zivimbele ukulimala kokulayisha amaphuzu ku-membrane. I-YDWPC ingancoma izinhlelo ze-pedestal kanye ne-subframe ezihambisanayo zezidingo ezithile zephrojekthi.
Lapho i-YDWPC ifanela khona uhlu lwakho lwe-Tropical Decking
I-Ningbo Yida Wood Plastic Technology Co., Ltd. (I-YDWPC) iye yakhiqiza i-WPC decking, cladding, kanye ne-fence selokhu yasungulwa, ngokukhiqiza kwamanje okuhlanganisa i-co-extrusion kanye namaphrofayili akudala emisebenzi yangaphandle yokuhlala, yezentengiselwano, kanye neyomasipala. Umugqa wethu wokukhipha ohlangene ukhiqiza amaphrofayili e-YD140RH23 kanye ne-YD140S23 — ububanzi obuyi-140mm, ukuphakama okungu-23mm nge-cap ye-polymer engu-360° — elungiselelwe ukufakwa kwezindawo ezishisayo nezishisayo ezivulekile. Umugqa wethu wakudala uhlanganisa amaphrofayili ayisishiyagalolunye (YD150SH25, YD150RH30, YD150S20, YD150H30, YD150H25, YD142S10, YD140SH25, YD140S25, YD140RH25) ahlanganisa ububanzi obuyi-140-150mm kanye nokuphakama okungu-10-30mm kwezicelo ezimboziwe nezifakwe umthunzi.
Yonke imikhiqizo ye-YDWPC decking inezakhiwo ezilandelayo: ingangeni manzi, ayingeni umswakama, ayivimbeli ukukhunta, ayivimbeli izinambuzane, ayiqhekeki, ayishibiliki, ayigqwali, futhi ayinakekeli kahle. Ukumbozwa kwewaranti kusuka eminyakeni eyi-10 (amaphrofayili akudala) kuya eminyakeni engama-25 (amaphrofayili okuhlanganisa i-extrusion) kuye ngohlobo lomkhiqizo kanye nokusetshenziswa kwawo.
Kwabasabalalisi kanye nabakhi abahlola i-WPC decking yamaphrojekthi asezindaweni ezishisayo, amakhasi ethu omkhiqizo ojwayelekile wokubhekisela yilawa:
- I-YDWPC Co-Extrusion Decking (YD140RH23, YD140S23)
- I-YDWPC Classic Decking (amamodeli angu-9, ububanzi obungu-140-150mm)
