DONFOAM 812PIR HCFC-141B PASTER ROV CAV COLYOLS RAU PIR Block Ua Npuas Ncauj
DONFOAM 812PIR HCFC-141B PASTER ROV CAV COLYOLS RAU PIR Block Ua Npuas Ncauj
Lub hauv paus rau phau ntawv
Donfoam 812 / pir yog ib hom ntawm kev sib xyaw polyols nrog tus neeg sawv cev HCFC-141B ua cov khoom siv tshwj xeeb, cov khoom thauj mus los ntawm cov khoom lag luam tshwj xeeb uas npaj los ntawm reacyanting nws nrog isocyanate muaj cov txiaj ntsig nram qab no:
1.Foam muaj cov khoom siv tsis zoo thiab seem ruaj khov hauv txhua qhov kev qhia
2. Cov khoom lag luam ua npuas ncauj tuaj yeem txiav rau hauv cov duab sib txawv raws li cov kev xav tau ntawm cov khoom
3.Txhais kev ua thermal rwb thaiv tsev ua haujlwm
