Polyether polyol siv rau cov yeeb nkab rwb thaiv tsev, polyurethane ua npuas ncauj yog cov khoom siv los yog kev sib txuas ntawm cov ntaub ntawv qhwv ib ncig ntawm cov yeeb nkab uas retard qhov ntws ntawm lub zog hluav taws xob.
Polyurethane ua npuas ncauj pab tswj kom sov cov yeeb nkab kub kom tsis txhob muaj cua sov hauv cov kav dej thiab tiv thaiv kom khov los yog tawg hauv cov huab cua txias.
Cov yeeb nkab rwb thaiv tsev txo cov hluav taws xob poob mus rau qhov zoo thiab yog li txo cov nqi hluav taws xob.
Lub rwb thaiv tsev ntawm cov kav dej yog ib qho ntawm cov khoom siv feem ntau siv hauv cov tsev thiab cov qauv kev lag luam, muaj kev cuam tshuam loj rau kev txuag hluav taws xob.
Lub thermal conductivity coefficient ntawm polyurethane ua npuas ncauj yog qis dua li lwm yam ntaub ntawv rwb thaiv tsev xws li ntoo, pob zeb ntaub plaub thiab polystyrene, ua tsaug rau lub siab kaw ntawm tes ntawm nruj polyurethane foams.
Yog li ntawd, thermal rwb thaiv tsev los ntawm nruj polyurethane foams yog ntau dua li lwm yam ntaub ntawv rwb thaiv tsev.
Fuctions
Kev ua haujlwm ntawm Rigid Foam Polyether polyol rau cov yeeb nkab rwb thaiv tsev ua haujlwm peb lub hom phiaj tseem ceeb:
1, Kub rwb thaiv tsev: txo qhov tseem ceeb hauv kev hloov hluav taws xob ntawm thermal zog mus rau thiab los ntawm qhov chaw ntawm cov kav dej. Yog li, piping rwb thaiv tsev txuag lub zog.
2, Kev rwb thaiv tsev txias: kev tiv thaiv kev ya raws tsim thiab sau rau ntawm qhov chaw ntawm cov kav dej vim muaj qhov sib xyaw ua ke ntawm qhov chaw txias.
3, Kev Tiv Thaiv Tus Kheej: kev tiv thaiv ntawm cov neeg ua haujlwm raug mob kev sib cuag nrog lub ntsej muag ntawm cov kav dej.
Yam khoom tseem ceeb
BQ8017 yog ib hom kev sib xyaw polyol ntawm tag nrho cov dej siv hauv cov yeeb nkab rwb thaiv tsev.
BQ8017 polyurethane yeeb nkab rwb thaiv tsev muaj cov yam ntxwv hauv qab no:
Dej cua tshuab,
ozone depletion yog 0, ntsuab;
zoo heev flow zog,
zoo ceev,
cov khoom ntws zoo tshaj li cov yeeb nkab zoo tib yam zoo tshaj 10% ntawm tus neeg sawv cev tshuab;
zoo heev lub cev muaj zog ntawm cov npuas dej,
los ntawm lub teb chaws tsis kam mus creep;
tsis muaj teeb meem brittle ua npuas ncauj shrinkage,
zoo adhesion nrog tawm yeeb nkab rau kev tiv thaiv.
