Taw qhia

DonFoam 822 / PIR yog ib hom kev sib xyaw polyols nrog hcfc-141b foaming tus neeg sawv cev, nrog polyol ua cov khoom siv tseem ceeb, sib xyaw nrog tus neeg saib xyuas tshwj xeeb, tsim nyog rau kev rwb thaiv tsev ntawm kev tsim kho, kev thauj mus los, plhaub thiab lwm yam khoom .Cov khoom siv no tshwj xeeb tsim rau kab nruam .Cov khoom polyurethane npaj los ntawm reacting nws nrog isocyanate muaj cov nram qab no zoo:

1. Ua npuas ncauj muaj lub zog tsis sib xws thiab qhov ruaj khov ntawm txhua qhov kev qhia

2. Cov khoom ua npuas ncauj tuaj yeem txiav rau hauv cov duab sib txawv raws li qhov yuav tsum tau ua ntawm cov khoom

3. Kev ua haujlwm zoo thermal rwb thaiv tsev
