ʻO ka WPC Cladding vs. ka lāʻau kuʻuna: He loiloi kumukūʻai-pōmaikaʻi no nā mea kūkulu hale kalepa
Nā Manaʻo Koʻikoʻi
- ʻOi aku ke kumukūʻai o ka WPC (wood-plastic composite) co-extrusion cladding he 20-35% ʻoi aku ka nui ma mua o ka lāʻau palupalu i mālama ʻia akā hāʻawi i nā kumukūʻai mālama haʻahaʻa he 60-75% ma luna o ke ola holoʻokoʻa he 20 mau makahiki.
- Hoʻokumu ka ʻenehana co-extrusion i kahi pūpū polymer pale a puni ka WPC core, e hāʻawi ana i ke kūpaʻa UV, ke kūpaʻa i ka makū, a me ka paʻa ʻana o ke kala e ʻoi aku ka maikaʻi ma mua o ka uhi lāʻau paʻakikī premium.
- Ke neʻe nei nā mea kūkulu hale kalepa ma ʻEulopa a me ʻAmelika ʻĀkau i ka uhi WPC no ka mea ASTM D7032 a ʻo ka hoʻokō ʻana o EN 15534 e hoʻomaʻalahi i ka ʻae ʻia ʻana o ke code hale me ka hoʻopau ʻana i ka mālama ʻana i ka waihoʻoluʻu a me ka sila makahiki e koi ai ka uhi lāʻau.
- ʻO ke kumukūʻai holoʻokoʻa he 20 makahiki o ka loaʻa ʻana o ka uhi WPC he 35-50% haʻahaʻa ma mua o ka lāʻau ke noʻonoʻo ʻia ka hoʻololi ʻana i nā mea, ka hana no ka hoʻopau hou ʻana, a me nā kumukūʻai hoʻolei ʻana i ka hopena o ke ola.
ʻO ke kumukūʻai maoli o ka uhi lāʻau ʻaʻole i kamaʻilio ʻia e kekahi ma ke kahua noi
Ua hoʻohana au i nā makahiki he ʻumi i hala iho nei e kōkua ana i nā mea hoʻokomo mai i nā mea kūkulu hale ma ʻEulopa, ʻAmelika ʻĀkau, a me Asia Hikina Hema e hoʻokumu i nā mea hou aku no ke kūkulu ʻana i nā hale. Wpc Decking, pā, a me ke uhi ʻana mai nā hale hana Kina. Hoʻomaka pinepine ke kamaʻilio ʻana ma ke ʻano like: ua kuhikuhi ka mea kākau hale i ke uhi lāʻau (ʻo ia hoʻi ke kedera ʻulaʻula komohana, larch, a i ʻole ka paina thermowood), ke kumukūʻai o ka mea hana i ka mea a me ke kau ʻana, a neʻe ka papahana i mua me ka mea i ʻike ʻia he hopena kūpono i ke kumukūʻai.
ʻO ka mea i hoʻokomo ʻole ʻia i loko o ke kau mua ʻana, ʻo ia ke kumukūʻai mālama e hōʻiliʻili ʻia ana i kēlā me kēia makahiki ma hope o ke kau ʻana. Pono ke kala ʻana a i ʻole ka ʻaila ʻana i ka uhi lāʻau i kēlā me kēia 2-5 mau makahiki ma muli o ke ʻano, ka ʻike ʻia ʻana, a me ke ʻano o ka hoʻopau ʻana. Ma ʻEulopa ʻĀkau, kahi i koʻikoʻi ai ka ua, ka hau, a me ka UV, ʻo kahi hale kalepa me 500 mika kuea o ka uhi lāʻau e hoʻolilo i $3,000-6,000 no kēlā me kēia pōʻaiapuni mālama ma ke scaffolding, ka hana, a me nā mea hana - i kēlā me kēia 3 mau makahiki, no ke ola o ka hale.
Ke hōʻike aku nei au i nā mea hana ʻaelike a me nā mea nona ka hale i kahi hoʻohālikelike kumukūʻai ola he 20 mau makahiki ma waena o ka uhi lāʻau kuʻuna a me ka uhi WPC co-extrusion, makemake mau nā helu i ka WPC ma kahi palena koʻikoʻi. Eia ke ʻano o ka hana ʻana o kēlā loiloi.
He aha ka WPC Co-Extrusion Cladding a pehea e hana ʻia ai?
ʻO ka WPC (hui lāʻau-plastic) kahi mea ʻenekinia i hana ʻia mai ka hui ʻana o ka fiber lāʻau (maʻamau 50-60%), ka polymer thermoplastic (HDPE a i ʻole PP, 30-35%), a me nā mea hoʻohui hana (5-15%) me nā mea hoʻopaʻa UV, nā pigment kala, nā mea hoʻopili, a me nā fungicides. Hoʻomehana ʻia ka hui ʻana, kāwili ʻia, a hoʻopuka ʻia ma o kahi die e hana i nā papa me kahi ʻāpana keʻa kūlike.
ʻO ka co-extrusion ka holomua koʻikoʻi e hoʻokaʻawale i ka WPC cladding hou mai nā huahana composite hanauna mua. I ke kaʻina hana co-extrusion, hoʻopili ka lua o ka extruder i kahi papa pāpale polymer pale (maʻamau he 0.3-0.7mm ka mānoanoa) a puni ka WPC core i kona puka ʻana i waho o ka make mua. ʻO kēia papa pāpale - i hana ʻia me nā mea pale UV i hoʻopaʻa ʻia a me nā pigments kala - hana i kahi ʻili i hoʻopaʻa ʻia e pale ai i ka wood-fiber core mai ka makū komo ʻana a me ka hōʻino ʻana o UV.
ʻO ka hopena he papa uhi e like me ka lāʻau maoli (mahalo i nā ʻano palaoa i kālai ʻia i loko o ka papa pāpale) akā hana e like me ka polymer hana kiʻekiʻe. ʻO kā mākou ʻO ka uhi hoʻopili like ʻana o WPC YD216H25 ua hana ʻia ma kahi laina co-extrusion piha piha me ka nānā ʻana i ka mānoanoa o ka pāpale manawa maoli e hōʻoia i ka pale mau ma kēlā me kēia mika linear. Hana pū mākou i nā huahana hoʻohui - no nā papahana e pono ai kahi pūʻolo waho piha, kā mākou kahua pā WPC kaʻana like i ka ʻenehana co-extrusion like a me ka ʻōnaehana hoʻohālikelike kala.

E lilo ana kēia mau helu i mea koʻikoʻi loa ke noʻonoʻo ʻoe i ke kumukūʻai o nā scaffolding no nā hale kalepa he nui nā papahele, kahi e hiki ai i hoʻokahi pōʻaiapuni mālama ke kumukūʻai he $10,000-20,000 i nā lako komo wale nō.
Hoʻohālikelike Hana: Kū'ē i ka Makū, UV, a me nā Pepeke
No nā mea kūkulu hale kalepa, ʻo nā ana hana koʻikoʻi loa, ʻo ia ke kūpaʻa o ka nui i ka pōʻaiapuni o ka makū, ka paʻa ʻana o ke kala ma lalo o ka hōʻike ʻana o UV, a me ke kūʻē ʻana i ka hoʻouka kaua olaola (nā pepeke a me nā fungi).
- Ka omo ʻana o ka wai: Hoʻopili ka uhi lāʻau i ka 12-25% o ka makū ma ke kaumaha ke hoʻomaʻū ʻia, e hoʻoulu ai i ka pehu, ka warping, a me ke kīʻaha. Hoʻopili ka uhi co-extrusion WPC i ka emi ma mua o 1% o ka makū ma ke kaumaha - hoʻopaʻa ka papa pāpale polymer i ka ʻiʻo fiber lāʻau mai ka pili pololei ʻana me ka wai. ʻO ke ʻano kēia e mālama nā papa WPC i ko lākou mau ʻae ʻana i ka dimensional ma o ka ua, ka hau, a me nā pōʻaiapuni haumākū me ka ʻole o nā hakahaka hoʻonui a me nā mea paʻa e pono ai ka uhi lāʻau.

Hana Ahi a me ka Hoʻokō ʻana i nā Kānāwai Hale
ʻO ka hana ahi kahi kikoʻī koʻikoʻi no nā mea uhi kalepa, ʻoi aku hoʻi ma ʻEulopa ma hope o ka pōʻino o ka Grenfell Tower a me ka hoʻopaʻa ʻana o nā lula hale ma EU. Eia kahi e kū ai ka uhi WPC i ka ʻāina hana ahi:
ʻO ka hoʻopili ʻana o ka WPC maʻamau (me ka ʻole o nā mea hoʻohui pale ahi) e loaʻa pinepine i kahi helu Class C a i ʻole Class D ma lalo o ka ʻōnaehana hoʻokaʻawale ahi ʻEulopa EN 13501-1, kahi e kūlike ana me kahi hopena ahi e like me ka lāʻau medium-density. No nā hale kalepa e koi ana i ka hana ahi Class B, loaʻa nā ʻano hana WPC pale ahi e hoʻokomo i nā mea hoʻopihapiha mineral (aluminum trihydrate, magnesium hydroxide) ma 10-20% ukana.
Ua hoʻāʻo ʻia kā mākou WPC co-extrusion cladding me ka hoʻohui fire-retardant i ka EN 13501-1 Class B-s1,d0, kahi e hoʻokō ai i nā koi no nā hale ma luna o 18 mika ma ka hapa nui o nā mana aupuni ʻEulopa. Hoʻokomo ʻia ka mea hoʻohui pale ahi i loko o ka hui kumu i ka wā o ka hana ʻana - ʻaʻole ia he uhi ʻili e hiki ke pau i ka hala ʻana o ka manawa. ʻO ke ʻano kēia, he mea kūlohelohe ka hana ahi i ka mea a ʻaʻole e hōʻino ʻia me ka wā ʻino.
No nā papahana ʻAmelika ʻĀkau, pono ka uhi ʻana o WPC e kūlike me ASTM E84 (hoʻāʻo tunnel Steiner) no ka laha lapalapa a me ka ulu ʻana o ka uahi. ʻO ka maʻamau, loaʻa i nā ʻano hana WPC maʻamau kahi helu Class A a i ʻole Class I (index spread lapalapa 0-25, index developed smoke 0-450) i ka wā i hoʻāʻo ʻia e like me ASTM E84.
Ka Pono o ke Kau ʻana: Pehea e hōʻemi ai ʻo WPC i nā kumukūʻai hana ma ka pūnaewele
Ma waho aʻe o ka hana waiwai, hāʻawi ka WPC co-extrusion cladding i kekahi mau pono hoʻonohonoho e unuhi pololei ana i ka mālama kālā hana no nā papahana kalepa:
- ʻŌnaehana ʻūlū huna. Hoʻohana kā mākou uhi YD216H25 i kahi ʻūpā kila kila huna e paheʻe ana i loko o ke kahawai o loko o ka papa. ʻAʻohe kui maka, ʻaʻohe mea paʻa i ʻike ʻia, a hoʻopaʻa kēlā me kēia papa i ka papa aʻe me ka mamao kūlike. He 30-40% wikiwiki ka hoʻouka ʻana o kēia ʻōnaehana ma mua o ka uhi lāʻau paʻa maka no ka mea ʻaʻole pono ka mea hoʻonoho e wili mua, hoʻoheheʻe i lalo, a hoʻonohonoho paha i nā kui pākahi.
- ʻAʻole koi ʻia ka mālama mua ʻana. Pono pinepine nā papa uhi lāʻau i ke sila ʻana i ka hopena o ka palaoa, ka hoʻopiha ʻana i nā knot, a me ka hoʻoluʻu mua ʻana ma mua o ke kau ʻana. Ua mākaukau nā papa WPC e hoʻokomo pololei mai ka pūʻolo - ʻokiʻoki i ka lōʻihi, ʻokiʻoki, a neʻe i ka papa aʻe.
- Ka hoʻomanawanui kūlike o ka nui. Mālama nā papa WPC i hoʻopuka ʻia e ka hale hana i nā ʻae ʻana o ka nui o ±0.5mm ma o ka holo hana holoʻokoʻa. Hiki ke ʻokoʻa nā papa lāʻau kūlohelohe ma 2-5mm ka laulā a me ka mānoanoa ma waena o nā papa, e pono ai ke hoʻokaʻawale a me ke koho ʻana ma kahi. ʻO ke ana like o ka WPC ke ʻano o nā hui like a me ka hoʻonohonoho wikiwiki a hiki ke wānana ʻia.
- Kaumaha māmā. ʻO ke kaumaha o nā papa uhi WPC ma kahi o 2.0-2.5 kg no ka mika linear (no nā papa 216mm ka laulā), hoʻohālikelike ʻia me 3.0-4.5 kg no nā papa lāʻau paʻa like. Hoʻemi kēia hōʻemi kaumaha i ka luhi o ka mea hoʻonoho, hoʻomaʻalahi i ka logistics scaffolding, a hoʻohaʻahaʻa i ke kaumaha kūkulu ma ka envelope hale.
Nā Manaʻo Kuhihewa Maʻamau e pili ana i ka WPC Cladding
Ma koʻu ʻike i ke kōkua ʻana i nā mea hoʻolaha e hoʻololi mai ka lāʻau a i ka WPC, ke hālāwai pinepine nei au me nā manaʻo kuhihewa like. ʻO ka hoʻoponopono ʻana i kēia mau mea ma mua e pale aku i nā hewa pipiʻi:
Kuhihewa 1: "Me he mea lā he hoʻopunipuni ka WPC." He ʻano like a hana hou ʻia ko ka WPC hanauna mua. Hoʻopuka ka co-extrusion hou i nā ʻano lāʻau i kālai hohonu ʻia me ka ʻokoʻa o ke kala kūlohelohe. Ma kahi mamao o 3-5 mika (maʻamau no nā facades), ʻaʻole hiki i nā mea kūkulu hale akamai ke hoʻokaʻawale i ka WPC maikaʻi mai ka lāʻau me ka ʻole o ka hoʻopā ʻana. Hoʻohana kā mākou hana i nā wili CNC-engraved me nā ʻano palaoa mai nā laʻana lāʻau maoli, e hana ana i ka ʻokoʻa hohonu 0.5-0.8mm.
Kuhihewa 2: "Kaumaha loa ʻo WPC no ka hoʻoponopono hou ʻana." Ma 2.0-2.5 kg no ka mika linear no ka papa 216mm ka laulā, ʻoi aku ka māmā o ka WPC ma mua o ka hapa nui o nā uhi lāʻau paʻa. ʻO ka hopohopo maʻamau e puka mai ana mai ka huikau me nā papa papahele kūkulu. ʻAʻole kūkulu ʻia nā papa uhi a hana pū me nā ʻōnaehana batten maʻamau.
Kuhihewa 3: "ʻAʻole hiki iā WPC ke lawelawe i nā piʻo." ʻOiai ʻaʻole hiki i ka WPC ke kulou anu e like me ka lāʻau lahilahi, ʻo ka hoʻokumu ʻana i ka wela e ʻae i ke ʻano no nā piʻo mālie (radius ma luna o 3-4 mika). No nā piʻo paʻa, ʻo nā ʻaoʻao WPC palupalu me nā ʻiwi lahilahi e hoʻokipa i nā radii i lalo i 2 mika ke hoʻomehana ʻia i 80-100 degere C.
Ma muli o kēia mau kuhihewa e alakaʻi ai i nā mea kālai hale e hōʻole i ka WPC me ka ʻole o ka loiloi kūpono, paipai wau e hāʻawi i nā papa hoʻohālike kino no nā hoʻohālike ma ka pūnaewele. Ke ʻike ka mea kākau hale i kahi hāpana WPC 3x3 mika ma ka ʻaoʻao o ke kikoʻī lāʻau, makemake pinepine ka hoʻohālikelike ʻana i ka WPC no nā noi kalepa.
Nā Manaʻo Hoʻomau a me ke Kaiapuni
No nā mea kūkulu hale kalepa e alualu ana i nā palapala hōʻoia hale ʻōmaʻomaʻo (LEED, BREEAM, a i ʻole DGNB), hāʻawi ka WPC cladding i kekahi mau ʻano hōʻaiʻē:
- Nā mea i hana hou ʻia. Loaʻa i nā papa WPC he 50-60% o ka fiber lāʻau (i loaʻa mai nā ʻōpala lāʻau hana hou ʻia a me nā huahana ʻoki lāʻau) a me 30-35% HDPE hana hou ʻia (plastic hana hou ʻia ma hope o ka mea kūʻai aku). Kūpono kēia pakeneka o ka ʻike hana hou ʻia no LEED MR Credit: Building Product Disclosure and Optimization — Sourcing of Raw Materials.
- ʻAʻohe lāʻau paʻa wela. ʻO ka hoʻohana ʻana i ka WPC ma kahi o ka uhi ʻana i ka lāʻau paʻakikī tropical (Ipe, Cumaru, Balau) e hoʻopau i ka hopena o ka neoneo ʻana a me ka biodiversity e pili ana i ka ʻohi lāʻau tropical. Kūlike kēia me nā hōʻaiʻē BREEAM MAT 03 (Responsible Sourcing).
- Hiki ke hana hou ʻia i ka hopena o ke ola.Hiki ke wili ʻia ka uhi WPC a hoʻokomo hou ʻia i loko o kahi mea hou Huahana Wpci ka hopena o ke ola - ʻaʻole e like me ka uhi lāʻau i mālama ʻia me nā mea hoʻomalu, pono e hoʻolei ʻia ma ke ʻano he ʻōpala weliweli ma nā mana he nui.
Ma muli o ka hana ʻia ʻana o ka uhi WPC mai nā kahawai ʻōpala (nā olonā lāʻau hana hou a me ka plastic hana hou), hoʻoponopono ia i nā koi hoʻokele waiwai pōʻai e koi nui ʻia ana i nā kikoʻī kūʻai aupuni ʻEulopa.
Nā Nīnau i Nīnau Pinepine ʻia
Pehea ka hana ʻana o ka WPC co-extrusion cladding i nā aniau anuanu loa e like me Scandinavia?
Hana maikaʻi ka WPC co-extrusion cladding i ke anu nui no ka mea ʻaʻole e palupalu ka matrix polymer i nā mahana ma lalo o ka zero - ʻo ka mahana hoʻololi aniani o ka mea hoʻopaʻa HDPE ma kahi o -120°C. Ua hoʻāʻo ʻia kā mākou cladding no ka freeze-thaw cycle e like me EN 15534 (100 mau pōʻaiapuni mai -20°C a i +20°C me ka ʻike ʻole ʻia o ka haki ʻana, ka warping, a i ʻole ka delamination). Mālama ka papa pāpale i kona kūpaʻa ma o ka thermal cycling, ʻo ia ke ʻano hana hāʻule mua no nā huahana WPC hanauna mua me ka ʻole o ka co-extrusion. Pono nā mea hoʻonoho ma nā ʻāina Nordic e mālama i kahi āpau hoʻonui 3-5mm ma nā wēlau o ka papa e hoʻokipa i ka neʻe ʻana o ka thermal (hoʻonui ʻo WPC ma kahi o 1.5-2.0mm no kēlā me kēia mika linear me ka swing mahana 30°C).
Hiki ke pena ʻia a hoʻoluʻu ʻia paha ka uhi ʻana o ka WPC e hoʻololi i ke kala ma hope o ke kau ʻana?
ʻOiai hiki i ka uhi ʻana o WPC ke ʻae i ka pena a i ʻole ke kala, ʻaʻole au e paipai iā ia. Ua hoʻolālā kūikawā ʻia ka papa pāpale co-extrusion e pale aku i ka pipili ʻana o nā uhi ʻili - ʻo ia ka mea e hoʻolilo ai i ka mālama haʻahaʻa i ka wā mua. ʻAʻole e hoʻopili pono ka pena a i ʻole ke kala i ka ʻili o ka pāpale a e ʻili i loko o 1-2 mau makahiki. Inā makemake ʻoe i kahi kala kikoʻī, e kauoha i ka uhi ʻana i kēlā kala i ka wā o ka hana ʻana. ʻO kā mākou ʻano kala maʻamau e komo pū ana me 8 mau ʻano ʻano lāʻau (ʻoka, walnut, teak, kedera, lanahu, hina slate, lāʻau weathered, a me ke keʻokeʻo), a loaʻa nā kala maʻamau no nā kauoha ma luna o 5,000 mika kuea.
He aha ka helu ahi o ka uhi WPC maʻamau me ka ʻole o nā mea hoʻohui pale ahi?
ʻO ka hoʻopili ʻana o ka WPC maʻamau me ka ʻole o nā mea hoʻohui pale ahi e loaʻa pinepine ai kahi helu Euroclass D-s1,d0 a i ʻole C-s1,d0 ma lalo o EN 13501-1, kahi e like me ka lāʻau palupalu i mālama ʻole ʻia. No nā hale kalepa e koi ana i nā helu ahi kiʻekiʻe (Class B a ʻoi aku paha), e kuhikuhi i kā mākou ʻano hana pale ahi e loaʻa ai ka B-s1,d0. Ma ʻAmelika ʻĀkau, ʻo ka WPC maʻamau e loaʻa pinepine ai ka ASTM E84 Class A (flame spread index 0-25). E hōʻoia mau i ka hōʻike hoʻāʻo ahi no ka huahana kikoʻī a me ke kala āu e kauoha nei, no ka mea, hiki i nā pigments a me nā ʻano hana papa pāpale ke hoʻopilikia i ka hana ahi.
Pehea e lawelawe ai ka WPC cladding i ka ulu ʻana o nā mea olaola e like me ka ʻōpala a me ka limu?
He kūpaʻa loa ka WPC co-extrusion cladding i ka ulu ʻana o ka meaola no ka mea ʻaʻole hāʻawi ka papa pāpale polymer i kahi kumu meaʻai organik no nā spores mold a i ʻole algae. Eia nō naʻe, ma nā wahi malu, pulu mau (nā paia e kū pono ana i ka ʻākau i nā aniau pulu), hiki ke ulu ka biofilm o ka ʻili ma luna o kekahi mea waho. Inā hana ʻia kēia, ua lawa ka hoʻomaʻemaʻe ʻana me kahi hopena detergent akahai a me kahi palaki palupalu - ʻaʻole like me ka uhi lāʻau, kahi e pono ai ka mālama kemika a me ke one hou ʻana e wehe i ka mold i hoʻokomo ʻia. Hāʻawi nā mea hoʻohui fungicide i loko o ka hui kumu WPC i kahi papa pale hou aʻe e kūʻē i ka palaho fungal inā komo ka makū i kahi ʻoki a i ʻole ka ʻōpala.
He aha ka palapala hoʻokō a Yida e hāʻawi ai no ka WPC co-extrusion cladding?
Hāʻawi mākou i kahi palapala hoʻokō palena palena 15 makahiki e uhi ana i ka pono o ke kūkulu ʻana, ka mae ʻana o ke kala (ʻoi aku ma mua o 5 mau ʻāpana Delta E i loko o ka manawa palapala hoʻokō), a me ka delamination papa pāpale co-extrusion. Loaʻa ka palapala hoʻokō ke hoʻokomo ʻia ka cladding e like me kā mākou alakaʻi hoʻonohonoho (me ka ea kūpono, ka hoʻopaʻa ʻana, a me nā kikoʻī o ka hakahaka hoʻonui) a ʻaʻole uhi i ka pōʻino mai ka hoʻohana pono ʻole, ka hopena, a i ʻole nā hoʻololi ʻae ʻole ʻia. Hāʻawi pū mākou i nā koho palapala hoʻokō i hoʻonui ʻia he 25 makahiki no nā papahana i ʻoi aku ma mua o 10,000 mika kuea. ʻO nā palapala hoʻokō piha, me nā hōʻike hoʻāʻo no kēlā me kēia ICC-ES a me EN 15534, i hāʻawi ʻia me kēlā me kēia ukana.
