Dab tsi yog qhov formulation ntawm PU ua npuas ncauj
PU ua npuas ncauj yog dab tsi?
PU ua npuas ncauj, tseem hu ua polyurethane ua npuas ncauj, yog ib hom khoom tsim los ntawm polymerizable esters, diisocyanates, thiab lwm yam tshuaj. Nws yog feem ntau siv nyob rau hauv ntau yam kev lag luam thiab kev siv vim nws cov versatility, durability, thiab affordability.
PU ua npuas ncauj feem ntau siv rau hauv kev tsim kho rau lub hom phiaj rwb thaiv tsev, vim nws muab cov khoom zoo thermal thiab acoustic rwb thaiv tsev. Nws kuj yog siv nyob rau hauv kev lag luam rooj tog rau cushioning thiab padding nyob rau hauv lub rooj zaum, sofas, thiab lwm yam upholstery. Hauv kev lag luam tsheb, nws yog siv rau hauv lub rooj zaum hauv tsheb los muab kev nplij siab thiab kev txhawb nqa.
Cov formulations ntawm polyurethane yog dab tsi?
Polyurethane-raws li ua npuas ncauj feem ntau yog tsim los ntawm polyurethane-based polyol resin, polyurethane-based copolymer polyol resin (co-polyol), dej, catalyst (los yog pob catalyst, feem ntau yog isocyanate xws li TDI lossis TM20) thiab surfactant.
PU (Polyurethane) ua npuas ncauj yog ntau yam, muaj kev ua tau zoo ntawm cov khoom siv rwb thaiv tsev uas siv ntau yam xws li rwb thaiv tsev boards, txau ua npuas ncauj, thiab insulating foams. Nws yog tsim los ntawm kev sib txuas ntawm ob yam tshuaj sib txawv, ib qho sib xyaw polyol thiab ib qho kev sib xyaw isocyanate, uas cuam tshuam cov tshuaj lom neeg los tsim ua npuas dej nrog ntau cov txiaj ntsig zoo.
