DONFOAM 82PIR HCFC-141B KEEB KEEB KEV TXHAWB COLYOLS RAU TOMAG PIR Block Ua npuas ncauj
Lub hauv paus rau phau ntawv
Donfoam 822 / pir yog ib hom ntawm kev sib xyaw polyols nrog tus neeg sawv cev HCFC-141B yog cov khoom siv tshwj xeeb, cov khoom siv nyiaj txiag tshwj xeeb npaj los ntawm reacyurethane tau npaj los ntawm reacyanting nws nrog isocyanate muaj cov txiaj ntsig nram qab no:
1. Ua npuas ncauj muaj lub zog muaj zog thiab seem ruaj khov hauv txhua qhov kev qhia
2. Cov khoom ua npuas dej tuaj yeem txiav rau hauv cov duab sib txawv raws li cov kev xav tau ntawm cov khoom
3. Cov rwb thaiv tsev thermal rwb thaiv tsev zoo
