Kev xav tiaspolyurethane ua npuas ncaujyog cov rwb thaiv tsev zoo tshaj plaws ntawm kev ua lag luam yog dav heev thiab muaj lub hauv paus tsim nyog. Tseeb, polyurethane ua npuas ncauj muaj thermal conductivity tsawg. Daim duab no tuaj yeem ncav cuag 0.26 - 0.37 W / m × degree, nyob ntawm seb muaj pes tsawg leeg thiab cov khoom siv, nrog rau cov thickness ntawm cov rwb thaiv tsev txheej.
Zoo heev adhesion. Cov npuas dej yog siv rau lub hauv paus los ntawm kev txau thiab tsis tas yuav tsum tau kho ntxiv. Tias yog vim li cas nws muaj peev xwm insulate lub ru tsev, phab ntsa lossis façade hauv 24 teev. Txhawm rau ua qhov rwb thaiv tsev, peb cov neeg ua haujlwm ua tib zoo npaj qhov chaw: ntxuav nws thiab degrease nws.
Daim ntawv thov ceev. Hauv qhov no, lub teeb yuag polyurethane ua npuas ncauj tsis muaj kev sib tw. Tau kawg, qhov ceev ntawm daim ntawv thov ntawm cov kua ua npuas dej nyob ntawm qhov kev teeb tsa ntawm cov phab ntsa, tus naj npawb ntawm cov plag tsev ntawm lub tsev, thiab lwm yam. Txawm li cas los xij, lwm cov kev xaiv rwb thaiv tsev tsis tuaj yeem muab cov txiaj ntsig zoo sib xws.
Efficiency ntawm polyurethane ua npuas ncauj rwb thaiv tsev. Ua tsaug rau daim ntawv thov txheej txheem, lub teeb yuag ua npuas ncauj tuaj yeem txau mus rau cov khoom ntawm txhua yam duab thiab mus rau qhov chaw nyuaj. Nyob rau hauv cov ntaub ntawv no, cov txheej txheem tawm zoo tsis muaj pov tseg, thiab txheej yog du thiab seamless. Qhov no ua kom yooj yim rau kev ua haujlwm tom ntej nrog rau saum npoo, thiab tseem ua rau cov txheej txheem thermal rwb thaiv tsev.
Lub neej ua haujlwm ntev. Peb tab tom tham feem ntau txog polyurethane ua npuas ncauj nrog kaw-cell qauv. Muab hais tias tag nrho cov kev khiav hauj lwm yuav tsum tau ua, lub txheej yuav kav ntev li ob peb xyoo lawm tsis tas yuav tsum tau kho dua tshiab.
Tshuaj lom neeg tsis kam. Yog tias cov cuab yeej siv rau kev thov polyurethane ua npuas ncauj tau ua raws, ces cov txheej txheem thermal rwb thaiv tsev yog tiv thaiv los ntawm pwm. Qhov tseeb yog tias thaum siv cov khoom ua kua, condensation tsis sib sau, thiab cov khoom nws tus kheej tsis sau cov dej noo los ntawm huab cua. Nws tseem yog ib qho tseem ceeb uas cov nas tsis tuaj yeem tsim zes nyob rau hauv ib txheej ntawm kaw-cell polyurethane.
Ib puag ncig tus phooj ywg. Kaw cell polyurethane feem ntau suav hais tias yog cov khoom siv tshuaj lom. Qhov no tsis yog lawm. Qhov tseeb yog tias tsuas yog cov khoom qub ntawm cov khoom muaj kuab lom (lawv muaj nyob rau hauv pawg txaus ntshai 2 thiab 3). Txawm li cas los xij, ib zaug sib xyaw, hnov mob thiab kho, lawv tsim muaj kev nyab xeeb tag nrho polyurethane.
