Donpipe 322 HCFC-141b puag muab polyols rau pipeline plhaub
Donpipe 322 HCFC-141b puag muab polyols rau pipeline plhaub
kuv NTRODUCTION
DonPipe 322 yog ib yam ntawm cov muab polyols nrog hcfc-141b li foaming neeg sawv cev, kev noj polyol raws li lub ntsiab raw khoom, tov nrog ib tug tshwj xeeb txoj kev pab. Qhov no cov ntaub ntawv uas haum rau txheej thermal rwb thaiv tsev zoo li uas yog siv rau cov dej, roj thiab cov nkev pipelines .Tus polyurethane khoom npaj los ntawm reacting nws nrog isocyanate muaj cov nram qab zoo:
- zoo compressive zog thiab seem stability
- siab nyob ze-cell npaum li cas thiab zoo waterproof kev ua tau zoo
- zoo rwb thaiv tsev kawm
