WPC Foam Board: He aha ia, Waiwai & Hoohana

He aha ka WPC Foam Board?

Kū ʻo WPC no Wood-Plastic Composite - kahi ʻano mea e uhi ana i nā mea i hoʻohui ʻia kahi i hui ʻia ai ka mea hoʻopiha lāʻau me kahi mea hoʻopili thermoplastic. Ma ka WPC foam board kūikawā, ua hana ʻia ka composite me nā mea hoʻohūhū kemika i ka wā o ka extrusion e hoʻoheheʻe ʻia i ka wela heheʻe a hoʻokuʻu i ke kinoea, e hana ana i kahi ʻano cellular e hoʻemi ana i ka nui o ka panel me ka ʻole o ka hoʻololi ʻana i nā waiwai mechanical. ʻO ka hopena, he 30-50% ka māmā ma mua o ka pā WPC paʻa o ka mānoanoa like, ʻoiai e hoʻopaʻa ana i ka paʻa ʻana, ka paʻakikī o ka ʻili, a me ka pale ʻana i ka wai e waiwai ai nā mea WPC i ke kūkulu ʻana a me nā noi lako.

Hoʻoholo ke kaʻina hana i ka hana hope o ka papa a wehewehe i ke kumu o ka hana ʻokoʻa ʻana o ka papa puaa WPC mai nā papa puaa ʻē aʻe ma ka mākeke.

He aha ka mea e komo ai i loko o kahi WPC Foam Board

• palaoa lāʻau (30–70% ma ke kaumaha): ʻO ka pulupulu lāʻau i kālai ʻia mai ka ʻōpala sawmill, nā lāʻau i hana hou ʻia, a i ʻole nā koena mahiʻai. Hāʻawi ka ʻike lāʻau i ka rigidity, ka paʻakikī o ka ʻili, a me nā hiʻohiʻona hana e hoʻokaʻawale ai i ka papa pahu WPC mai nā panela plastik āpau. ʻO ka ʻoi aku ka nui o ka lāʻau e hoʻonui i ka ʻoʻoleʻa a me ka paʻakikī o ka ʻili akā pono ke hoʻonohonoho pono e mālama i ka like ʻana o nā cell foam i ka wā extrusion.
• Thermoplastic polymer matrix (PVC, PE, a i ʻole PP): ʻO ka mea hoʻopili e hoʻopili i ka palaoa lāʻau, hāʻawi i ka pale wai o ka panel, a hoʻoholo i kona paʻa kemika a me UV. ʻO PVC ka matrix maʻamau i ka papa hana WPC foam board ma muli o kona kūpaʻa ʻana i ke ahi, ka paʻa ʻana o ka wā, a me ka launa pū me nā mea hoʻohui PVC maʻamau. Hoʻohana ʻia ka polyethylene-based WPC foam board i nā mea hoʻopili meaʻai a me nā mea hana waho kahi e hopohopo ai ka ʻike o ka chlorine PVC.
• Nā mea hoʻohāhā kemika: ʻO ka maʻamau ka azodicarbonamide a i ʻole ka sodium bicarbonate-based system e decompose i nā mahana extrusion e hoʻokuʻu i ke kinoea carbon dioxide. Hoʻokumu ke kinoea i ka ʻōnaehana kelepona e hoʻemi ana i ka nui o ka panel mai ka 1,400–1,600 kg/m3 o WPC paʻa i ka 600–900 kg/m3 i loko o nā panela pua. ʻO ka noʻonoʻo ʻana o ka mea hana foaming a me ka hāʻawi like ʻana i ke kaʻina hana koʻikoʻi e hoʻoholo ai i ka nui o ka panel, ka nui o ka cell, a me ka maʻalahi o ka ʻili.
• Nā mea hoʻohui - stabilisers, lubricants, coupling agents, pigments: ʻO nā mea hoʻopaʻa wela (calcium-zinc a i ʻole organotin i loko o nā hoʻokumu ʻana i ka PVC) e pale i ka hoʻohaʻahaʻa polymer i ka wā extrusion. Hoʻomaikaʻi ka maleic anhydride coupling agents i ka hoʻopili ʻana ma waena o ka palaoa lāʻau a me ka polimer matrix. Mālama nā Lubricants i ka viscosity hehee i ka wā extrusion. Hoʻohui ʻia nā UV stabilizers (HALS) i loko o nā ʻano hana i manaʻo ʻia no nā noi waho e pale i ka polymer degradation a me ka ʻili o ka ʻili mai ka lōʻihi o ka ʻike ʻana o ka lā.

Ua pale ʻia ka WPC Foam Board?

ʻAe — ʻAʻole kūʻē ka WPC foam board no nā noi waho a me ka semi-outdoor. ʻO ke ʻano o ka ʻūhā paʻa i hoʻopaʻa ʻia e pale i ka komo ʻana o ka wai nui, a hāʻawi ka polymer matrix i ke kūʻokoʻa kūʻokoʻa i ka ulu ʻana o ka fungal, ka hoʻouka ʻana i nā pepeke, a me ka pala e hoʻohaʻahaʻa i ka lāʻau maoli. Eia nō naʻe, he ʻano ʻenehana kikoʻī ko ka "eather resistant" i ʻokoʻa mai ka "ʻaʻole i hoʻopilikia ʻia e nā kūlana o ka wā āpau," a ʻo ka hoʻomaopopo ʻana i kēia ʻokoʻa e pale i ka hoʻohana hewa ʻana:

Kū'ē Kū'ē i ka Lewa vs. Nā Papa Kū'ē Kū'ē - He Koʻikoʻi Koʻikoʻi

ʻO ka huaʻōlelo "foam board" i ka hoʻohana ʻana i kēlā me kēia lā e uhi i nā huahana ʻokoʻa me ke kū kūʻē ʻē aʻe. ʻO nā papa kumu pahu kuʻuna maʻamau i hoʻohana ʻia i ka hana noʻeau a me ka hana lima, nā hōʻike hōʻikeʻike, a me nā ʻano hoʻohālike hoʻolālā he polystyrene foam core i hoʻopaʻa ʻia ma waena o ka pepa a i ʻole nā ​​​​pepa ʻili ʻili. ʻAʻole kūpaʻa kēia mau huahana i ka wā - ʻo ka pepa e kū pono ana e hoʻomoʻa i ka makū i loko o nā hola o ka ʻike ʻana i waho, hāʻule ka hoʻopaʻa ʻana i ke alo i ka huʻa i ka wā pulu, a ʻaʻohe kūpaʻa o ka polystyrene core i ka wā e hemo ai nā alo. ʻO ka haʻalele ʻana i kahi papa ʻōhua maʻamau i waho i ka ua no ka lā hoʻokahi, ʻaʻole hiki ke hoʻohana ʻia.

ʻAʻohe nāwaliwali like ʻole o ka WPC foam board. ʻAʻohe pepa maka e hoʻoheheʻe ʻia, ʻaʻohe ʻāpana pepa e komo i ka makū, a ʻaʻohe paʻa paʻa ma waena o nā papa e hāʻule ma lalo o nā kūlana pulu. ʻO ka ʻāpana āpau o ka panel he mea like like ia mai ke alo a i ke alo. Hoʻokomo ʻia ka papa puaa WPC i loko o ka wai no 24 mau hola a laila hoʻihoʻi ʻia a maloʻo e hōʻike ana ma lalo o 0.5% o ka hoʻololi ʻana a ʻaʻohe nalowale o ka kūpaʻa o ke kūkulu ʻana i nā māka maikaʻi.

ʻAʻole wai paha ka papa ʻo Foam Core? — Ka wehewehe ana i ka huikau

ʻAʻole wai wai ka papa kumu pahu maʻamau (pepa polystyrene foam e kū pono ana). ʻO ka papa puaa WPC. ʻO ka papa puaa PVC (Celuka a i ʻole ʻano ʻano puaʻa manuahi, me ka ʻole o ka palaoa lāʻau) ʻaʻohe wai. He mea koʻikoʻi kēia ʻokoʻa no ka mea hiki ke wehewehe ʻia nā huahana ʻekolu ma ke ʻano he "foam board" i ka hoʻohana maʻamau, akā ʻokoʻa ko lākou hana ʻana i ka wai.

• ʻO ka papa puaa WPC — waterproof: Hoʻopili piha ka polimer matrix i nā ʻāpana palaoa lāʻau i ka wā extrusion, me ka waiho ʻole ʻana i ke ala mau no ka wai e komo i ka panel. ʻOi aku ka nui o ka huina hoʻopili wai ma kahi papa ʻōhua WPC maʻemaʻe ma mua o 85 degere, e hōʻike ana i ke ʻano hydrophobic. Hōʻike nā hualoaʻa hoʻāʻo kaiapuni (ASTM D1037 a i ʻole ka like) i ka hoʻoheheʻe ʻia ʻana o ka wai ma lalo o 1% ma ke kaumaha ma hope o ka hoʻoinu ʻana he 24-hola no nā māka maikaʻi.
• ʻO ka papa pahu pahu maʻamau (pepa polystyrene) — ʻaʻole wai wai: Hoʻopili ka pepa e kū ana i ka wai ma ka hana capillary i loko o nā minuke o ka pili. I ka manawa e komo ai ka makū o ka pepa e kū ana, e palupalu ka pa'a pa'a ma waena o ke alo a me ka hu'ahu'a, pehu a po'i ka pepa, a lilo ka papa i kona 'ili palahalaha a me ka pa'a o ke kino. Hoʻohana ʻia kēia mau huahana no ka hoʻohana maloʻo i loko wale nō a ʻaʻole pono e huikau me nā mea papa pahu wai wai.
• ʻO nā papa kumu pahu wai wai (me ka alumini a i ʻole ke alo HDPE) - pale i ka wai akā kaupalena ʻia: Hoʻohana kekahi mau papa kumu pahu i ka pepa alumini a i ʻole nā alo polyethylene kiʻekiʻe i hoʻopaʻa ʻia i ka pahu polystyrene. ʻAʻole paʻa kēia i ka wai ma ka ʻili akā hiki ke hoʻopili ʻia i ke komo ʻana a me ka delamination ma ka laina paʻa paʻa inā hiki ka wai i ka pilina pili. Ua kūpono lākou no nā wahi pulu me nā ʻaoʻao i hoʻopaʻa ʻia akā ʻaʻole like ia me ka papa ʻōhua WPC homogeneous i ka hoʻomau mau ʻana i waho.

Nā noi WPC Foam Board — Kahi e hana maikaʻi ai

ʻO ka hui pū ʻana o ka hana wai ʻole, ka machinability, a me ka maikaʻi o ka ʻili e ʻae i ka pena, laminate, a me ka paʻi pololei ʻana e kūpono i ka papa pua WPC ma kahi ākea ākea ākea ma mua o nā mea ʻē aʻe. Hōʻike nā noi ma lalo nei i nā mea hoʻohana waiwai kiʻekiʻe loa kahi e loaʻa ai i nā waiwai o WPC foam board nā pono kūpono ma mua o nā mea hoʻokūkū.

Pehea e hana ai me ka WPC Foam Board — Ke alakaʻi hoʻomaʻamaʻa

ʻOkoʻa ka hana ʻana o WPC foam board mai ka lāʻau paʻa a me ka papa pahu pahu maʻamau, a ʻo ka hoʻomaopopo ʻana i kēia mau ʻokoʻa e pale aku i nā hewa maʻamau e hoʻopuka ai i nā hopena maikaʻi ʻole me nā panela maikaʻi.

• ʻOki - e hoʻohana i nā ʻāpana carbide: ʻO nā lau kila māmā holo kiʻekiʻe (HSS) hikiwawe loa i ka WPC foam board abrasive wood-polymer composite structure. ʻO nā ʻoki ʻoki pōʻai a me nā ʻāpana alala e mālama i ka ʻoi o ka lihi ma o nā hana ʻoki ʻoki piha. E hoʻohana i ka maka niho maikaʻi (60-80 niho no ka 250 mm maka) e hōʻemi i ka ʻoki ʻana o ka ʻili ma ka ʻoki ʻoki. Pono e haʻahaʻa ka nui o ka hānai - lohi ka wela e hoʻoheheʻe ai i ka polimer matrix a hoʻohua i kahi ʻōpala a wela; hikiwawe loa ke kumu o ka nahae o ka ili.
• Hoʻopaʻa - e hoʻohana i nā wiliwili wili a me nā lua hoʻokele mua. ʻO ka papa puaa WPC holds fasteners well through mechanical engagement of the screw thread in the foam matrix. Coarse-thread screws (equivalent to type 17 self-drilling or standard wood screws with widely spaced threads) provide better pull-out resistance than fine-thread screws in foam materials. Pre-drilling prevents surface cracking in denser grade panels, particularly within 20 mm of panel edges where the cellular structure is more compressed.
• Hoʻopaʻa paʻa - hoʻohana i ka mea hoʻoheheʻe a i ʻole PVC-hoʻopili pili. Ua kaupalena ʻia ka hoʻopili ʻana o ka lāʻau PVA i ka wai i ka WPC foam board no ka mea ʻaʻole komo ka wai polymer hydrophobic i ka wai. Hoʻopili i ka mea hoʻopili (neoprene a i ʻole solvent-based), PVC paipu sima, a i ʻole ka papa hana SMP polymer adhesive hāʻawi i nā mea paʻa hilinaʻi i ka ikaika tensile piha o ka panel. No ka hoʻohana ʻana i ka laminate, hoʻopili ʻia ka mea hoʻopili pili i ka solvent ma nā ʻaoʻao ʻelua a ʻae ʻia e lilo i maloʻo hoʻopā ma mua o ke kaomi ʻana e hoʻopuka koke i nā mea paʻa ikaika kiʻekiʻe.
• Pena — ʻaʻole koi ʻia ke kumu mua ma nā māka maʻemaʻe-ili, ʻōlelo ʻia ke one māmā: ʻO ka ʻili maʻemaʻe o WPC foam board e ʻae pololei i ka pena acrylic i hoʻokumu ʻia i ka wai i ka hapa nui o nā noi. ʻO ke one māmā me 120-180 grit pepa ma mua o ka pena ʻana e hoʻomaikaʻi i ka hoʻopili mīkini ma o ka hana ʻana i ke ʻano microscopic surface. No ka hoʻohana ʻana i waho a i ʻole nā ​​​​mea hoʻonani kiʻekiʻe, hoʻomaikaʻi ke kumu hoʻoheheʻe i ka hoʻopili ʻana a me ka kūlike o ka ʻili. Mai hoʻohana i nā lacquers polyurethane me ka ʻole o ka hoʻāʻo ʻana - hoʻouka kekahi mau ʻōnaehana hoʻoheheʻe i ka PVC polymer matrix a hoʻoulu i ka palupalu a me ka huhū.
