Kev taw qhia luv luv ntawm polyurethane foaming tshuab

Polyurethane foaming tshuab yog cov cuab yeej tshwj xeeb rau polyurethane ua npuas ncauj. Ntev npaum li cov khoom siv polyurethane raw khoom (isocyanate tivthaiv thiab polyether polyol tivthaiv) cov ntsuas kev ua tau zoo raws li qhov yuav tsum tau ua ntawm cov mis. Los ntawm cov khoom siv no tuaj yeem tsim cov khoom zoo sib xws, tsim nyog ua npuas ncauj. Nws yog polyether polyol thiab polyisocyanate nyob rau hauv lub xub ntiag ntawm foaming neeg sawv cev, catalyst, emulsifier thiab lwm yam tshuaj additives, tom qab tshuaj tiv thaiv foaming thiab ua npuas ncauj. Polyurethane foaming tshuab tuaj yeem siv rau tsheb sab hauv kho kom zoo nkauj, thermal rwb thaiv tsev phab ntsa txau, thermal rwb thaiv tsev pipeline manufacturing, tsheb kauj vab thiab maus taus rooj sponge ua.
