Dab tsi yog Polyurethane Insulation Foams rauSolar Water Heaters?
Polyurethane rwb thaiv tsev foams yog ib qho kev daws teeb meem zoo rau thermal rwb thaiv tsev hauv lub hnub ci dej rhaub. Cov foams no muaj cov cuab yeej tiv thaiv cua sov zoo, kom ntseeg tau tias cov dej khaws cia tseem kub rau lub sijhawm ntev, txawm tias nyob hauv huab cua txias. Nrog rau cov thermal conductivity tsawg, polyurethane ua npuas ncauj txo qhov kub poob, kev txhim kho tag nrho cov txiaj ntsig ntawm lub hnub ci dej rhaub dej.
Ib qho ntawm qhov zoo ntawm polyurethane rwb thaiv tsev yog nws lub teeb yuag thiab ruaj khov, ua rau nws yooj yim rau kev thov thiab siv tau ntev. Cov npuas dej muab ib txheej txheej ntawm rwb thaiv tsev, ua kom muaj kev tiv thaiv thermal zoo thoob plaws tag nrho cov kab ke. Tsis tas li ntawd, nws yog resistant rau ya raws, tshuaj, thiab degradation, uas prolongs lub lifespan ntawm lub rhaub dej.
Los ntawm kev txo cov cua sov poob, polyurethane rwb thaiv tsev foams pab txhawb kev txuag hluav taws xob thiab txo qhov kev cia siab ntawm cov khoom siv hluav taws xob ntxiv rau cov dej cua sov, ua rau lawv xaiv eco-friendly thiab raug nqi xaiv rau hnub ci dej rhaub.
Lub tshav kub preservation dej tank ntawm lub hnub ci dej rhaub yog ua los ntawm nruj polyurethane ua npuas ncauj.
Rigid polyurethane ua npuas ncauj yog ib tug ntom microporous ua npuas ncauj tsim los ntawm polymerization ntawm isocyanate thiab polyol ua raw cov ntaub ntawv.
Nws muaj cov khoom zoo xws li lub teeb yuag, lub zog tshwj xeeb, impermeability, tsis-hygroscopicity, rwb thaiv tsev, shockproof, suab nqus, roj kuj thiab tshuaj corrosion kuj.
Piv nrog rau lwm cov yas ua npuas ncauj, nws kuj muaj cov yam ntxwv ntawm kev tsis muaj tshuaj lom, tsis muaj ntxhiab tsw, tsis zoo npuas thiab kub tsis kam. Nws muaj zog nws tus kheej-adhesion rau hlau, pob zeb, masonry, ntoo, iav, fiber ntau, thiab lwm yam, thiab cov khoom luam tawm nrog ntxiv nplaim taws yuav tua lawv tus kheej thaum nyob deb ntawm hluav taws. Hauv kev siv, kev siv tshuab nrawm nrawm yog siv, uas tuaj yeem muab pov rau hauv prefabricated panels lossis cov khoom siv. Nws tseem tuaj yeem ua foamed rau ntawm qhov chaw, nrog cov cuab yeej txheej txheem yooj yim, kev tsim kho siab thiab ua paug me me rau ib puag ncig.
