Vim tias WPC co-extrusion cladding tsis tas yuav tsum tau saib xyuas txhua xyoo - tsis muaj staining, tsis muaj sealing, tsis muaj oiling - tag nrho 20-xyoo tus nqi ntawm kev muaj yog 35-50% qis dua li cov ntoo mos uas tau kho thiab 55-65% qis dua li cov ntoo tawv zoo. Cov lej no yuav ua rau neeg xav tsis thoob ntxiv thaum koj suav nrog tus nqi ntawm cov scaffolding rau cov tsev lag luam ntau txheej, qhov twg ib lub voj voog txij nkawm tuaj yeem raug nqi $ 10,000-20,000 rau cov khoom siv nkag xwb.
Kev Sib Piv Kev Ua Tau Zoo: Kev Tiv Thaiv Dej, UV, thiab Kab Tsuag
Rau cov neeg ua lag luam, cov ntsuas kev ua tau zoo uas tseem ceeb tshaj plaws yog qhov ruaj khov ntawm qhov ntsuas dej noo, kev khaws xim thaum raug UV, thiab kev tiv thaiv kab mob (kab thiab pwm).
- Kev nqus dej noo: Cov ntoo cladding nqus tau 12-25% dej noo los ntawm qhov hnyav thaum saturated, ua rau o, warping, thiab cupping. WPC co-extrusion cladding nqus tsawg dua 1% dej noo los ntawm qhov hnyav - lub hau polymer txheej kaw lub hauv paus ntoo fiber los ntawm kev sib cuag dej ncaj qha. Qhov no txhais tau tias WPC boards tswj lawv qhov kev kam rau siab los ntawm nag, daus, thiab cov voj voog dej noo yam tsis muaj qhov sib txawv thiab kev kho uas cov ntoo cladding xav tau.
- Kev tiv thaiv UV: Cov ntoo uas tsis muaj kev tiv thaiv yuav lwj thaum raug hluav taws xob UV - lignin hauv cov ntoo fiber tawg, ua rau saum npoo hloov xim grey thiab fuzzy hauv 6-12 lub hlis ntawm kev raug. Txawm hais tias qee tus kws kes duab vajtse txaus siab rau qhov kev hloov pauv ntuj no, cov tswv tsev lag luam feem ntau tsis nyiam. WPC co-extrusion cladding khaws nws cov xim qub rau 15-25 xyoo vim tias cov txheej hau muaj cov tshuaj UV stabilizers (feem ntau HALS - hindered amine light stabilizers - ntawm 2-4% loading) uas nqus thiab dissipate UV zog ua ntej nws mus txog cov ntoo fiber core.
- Kev tiv thaiv kab thiab fungal: Cov ntoo cladding muaj kev phom sij rau cov kab ntsaum, cov kab uas tho ntoo, thiab cov kab mob fungal - tshwj xeeb tshaj yog nyob rau hauv huab cua sov thiab noo noo. WPC cladding muaj cov tshuaj tua kab mob thiab cov tshuaj tua kab sib xyaw rau hauv cov khoom tseem ceeb thaum lub sijhawm tsim khoom, muab kev tiv thaiv kab mob tsis tas siv tshuaj kho tom qab tsim khoom.
Kev Ua Haujlwm Hluav Taws thiab Kev Ua Raws Cai ntawm Lub Tsev
Kev ua tau zoo ntawm hluav taws yog ib qho tseem ceeb ntxiv rau cov ntaub ntawv cladding lag luam, tshwj xeeb tshaj yog nyob hauv Tebchaws Europe tom qab Grenfell Tower kev puas tsuaj thiab tom qab ntawd kev nruj ntawm cov cai tswjfwm hauv tsev thoob plaws EU. Nov yog qhov uas WPC cladding sawv cev rau qhov kev ua tau zoo ntawm hluav taws:
Cov txheej txheem WPC cladding (tsis muaj cov tshuaj ntxiv uas tiv taus hluav taws) feem ntau ua tiav qib C lossis D raws li European EN 13501-1 kev faib hluav taws, uas sib raug rau qhov hluav taws kub zoo ib yam li cov ntoo nruab nrab. Rau cov tsev lag luam uas xav tau kev ua haujlwm hluav taws kub Class B, cov qauv WPC tiv taus hluav taws muaj uas suav nrog cov khoom siv ntxhia (aluminium trihydrate, magnesium hydroxide) ntawm 10-20% kev thauj khoom.
Peb lub WPC co-extrusion cladding nrog cov qauv hluav taws kub tau raug sim rau EN 13501-1 Class B-s1,d0, uas ua tau raws li cov kev cai rau cov tsev siab tshaj 18 meters hauv feem ntau European jurisdictions. Cov tshuaj ntxiv uas tiv taus hluav taws tau muab tso rau hauv cov khoom tseem ceeb thaum lub sijhawm tsim khoom - nws tsis yog ib txheej txheej uas tuaj yeem lwj mus raws sijhawm. Qhov no txhais tau tias kev ua haujlwm hluav taws yog qhov muaj nyob rau hauv cov khoom siv thiab tsis lwj mus raws li huab cua.
Rau cov haujlwm North American, WPC cladding yuav tsum ua raws li ASTM E84 (Steiner tunnel test) rau kev kis hluav taws thiab kev loj hlob ntawm cov pa luam yeeb. Cov qauv WPC feem ntau ua tiav qib A lossis Class I (qhov ntsuas hluav taws 0-25, qhov ntsuas pa luam yeeb 0-450) thaum kuaj raws li ASTM E84.
Kev Txhim Kho Zoo: Yuav Ua Li Cas WPC Txo Cov Nqi Ua Haujlwm ntawm Qhov Chaw
Tshaj li kev ua tau zoo ntawm cov khoom siv, WPC co-extrusion cladding muaj ntau qhov zoo ntawm kev teeb tsa uas txhais ncaj qha rau kev txuag nyiaj ua haujlwm rau cov haujlwm lag luam:
- Zais cia kaw lus kaw lus. Peb lub YD216H25 cladding siv cov hlau stainless hlau zais uas swb rau hauv lub board sab hauv channel. Tsis muaj ntsia hlau ntsej muag, tsis muaj cov khoom siv pom tseeb, thiab txhua lub board xauv rau hauv qhov tom ntej nrog qhov sib nrug sib xws. Lub kaw lus no yog 30-40% sai dua rau kev teeb tsa dua li lub ntsej muag ntoo cladding vim tias tus neeg teeb tsa tsis tas yuav tsum tau ua ntej-tua, countersink, lossis teeb tsa cov ntsia hlau ib leeg.
- Tsis tas yuav kho ua ntej. Cov ntoo cladding boards feem ntau xav tau qhov kawg-grain sealing, knot filling, thiab pre-staining ua ntej installation. WPC boards npaj txhij rau nruab ncaj qha los ntawm lub pob - txiav kom ntev, clip, thiab tsiv mus rau lub board tom ntej.
- Kev kam rau siab sib xws. Cov laug cam WPC uas ua los ntawm lub Hoobkas muaj qhov ntev thiab dav ntawm ±0.5 hli thoob plaws tag nrho cov khoom tsim tawm. Cov laug cam ntoo ntuj tuaj yeem sib txawv ntawm 2-5 hli ntawm qhov dav thiab tuab ntawm cov laug cam, uas yuav tsum tau cais thiab xaiv ntawm qhov chaw. Qhov ntev ntawm WPC sib xws txhais tau tias cov pob qij sib xws thiab kev teeb tsa sai thiab kwv yees tau.
- Qhov hnyav sib dua. Cov laug cam WPC cladding hnyav kwv yees li 2.0-2.5 kg ib 'meter' linear (rau cov laug cam dav 216mm), piv rau 3.0-4.5 kg rau cov laug cam ntoo sib npaug. Qhov kev txo qhov hnyav no txo qhov kev qaug zog ntawm tus neeg teeb tsa, ua kom yooj yim rau kev thauj mus los ntawm scaffolding, thiab txo cov khoom siv ntawm lub tsev.
Kev Nkag Siab Yuam Kev Txog WPC Cladding
Los ntawm kuv txoj kev paub pab cov neeg faib khoom hloov ntawm cov ntoo mus rau WPC, kuv ntsib tib qho kev nkag siab yuam kev ntau zaus. Kev daws cov no ua ntej yuav tiv thaiv tau qhov yuam kev kim heev:
Kev nkag siab yuam kev 1: "WPC zoo li cuav." WPC tiam thawj muaj cov qauv zoo sib xws, rov ua dua. Cov txheej txheem co-extrusion niaj hnub no tsim cov qauv ntoo-nplej uas muaj xim sib txawv. Ntawm 3-5 meters saib deb (ib txwm rau cov facades), txawm tias cov neeg ua vaj tse paub dhau los kuj tsis tuaj yeem paub qhov txawv ntawm WPC zoo los ntawm cov ntoo yam tsis tau kov nws. Peb cov khoom siv CNC-engraved rollers nrog cov qauv noob los ntawm cov qauv ntoo tiag tiag, tsim qhov sib txawv tob 0.5-0.8 hli.
Kev nkag siab yuam kev 2: "WPC hnyav dhau rau kev kho dua tshiab." Ntawm 2.0-2.5 kg ib 'meter' linear rau lub rooj tsavxwm dav 216 hli, WPC sib dua li feem ntau cov ntoo tawv cladding. Qhov kev txhawj xeeb feem ntau yog los ntawm kev tsis meej pem nrog cov qauv decking boards. Cladding boards yog non-structural thiab ua haujlwm nrog cov qauv batten.
Kev nkag siab yuam kev 3: "WPC tsis tuaj yeem tswj cov kab nkhaus." Txawm hais tias WPC tsis tuaj yeem khoov txias zoo li cov ntoo nyias nyias, kev tsim cua sov tso cai rau kev tsim cov duab rau cov nkhaus mos mos (radius tshaj 3-4 meters). Rau cov nkhaus nruj dua, cov ntaub ntawv WPC yooj ywm nrog cov cores nyias dua tuaj yeem ua kom muaj radii qis dua 2 meters thaum cua sov rau 80-100 degrees C.
Vim tias cov kev nkag siab yuam kev no ua rau cov kws kes duab vajtse tsis lees txais WPC yam tsis muaj kev ntsuam xyuas ncaj ncees, kuv xav kom muab cov qauv piv txwv rau cov qauv hauv tsev. Thaum tus kws kes duab vajtse pom cov qauv WPC 3x3 meter nrog rau cov lus qhia ntoo, qhov kev sib piv yuav luag ib txwm nyiam WPC rau kev siv lag luam.
