Donpipe 322 HCFC-141b tushe saje polyols ga bututun harsashi
I GABATARWA
DonPipe 322 ne wani nau'i ne na saje polyols da hcfc-141b kamar yadda foaming wakili, shan polyol matsayin babban albarkatun kasa, hadawa da musamman karin. Wannan abu dace da m thermal rufi bawo wanda ake amfani da ruwa, da man fetur da kuma iskar gas bututun .An polyurethane samfurin shirya ta maida martani da shi tare da isocyanate yana da wadannan abũbuwan amfãni:
- kyau compressive ƙarfi da girma da kwanciyar hankali
- high kusa-cell kudi da kuma kyau hana ruwa yi
- kyau rufi yi
