Donpipe 311 dej puag sib xyaw polyols rau cov kav dej
Taw qhia
DonPipe 311 yog ib hom kev sib xyaw polyether polyol nrog dej ua tus neeg sawv cev foaming, polyol ua cov khoom siv tseem ceeb, sib xyaw nrog tus neeg sawv cev tshwj xeeb.Nws yog tsim los rau propping dej, roj los yog roj pipelines, rooj tog thiab lwm yam khoom, kuj nrog noo noo pov thawj thiab kub preservation functions.Cov khoom polyurethane npaj los ntawm reacting nws nrog isocyanate muaj cov hauv qab no zoo:
- Ib puag ncig tus phooj ywg, tsis ua kom puas ozone txheej
--High compressive zog ntawm ua npuas ncauj
--Zoo thiab du Ua npuas ncauj cell, nrog zoo waterproof thiab noo noo-pov thawj kev ua tau zoo
