Polyurethane txhav ua npuas ncauj yog tam sim no thoob ntiaj teb lees paub tias yog cov khoom siv rwb thaiv tsev zoo tshaj plaws.Nws muaj cov thermal conductivity tsawg, zoo load kuj, siab dabtsi yog khoov zog, tsis muaj dej nqus, tsis lwj, tsis muaj kab-noj nas tom, zoo nplaim retardancy thiab loj kub kuj ntau yam.
Lub khoos phis tawj yog siv los tswj cov kab ntau lawm, kom lub siab kub foaming polyurethane thiab cov xim-coated steel phaj yog sib xyaw ua ke thiab nruj ua ke.Cov xim hlau tsis nruj thiab cov khoom siv tshuaj mos yog ua ke nrog polyurethane PU ua npuas ncauj ua tshuab los tsim kev tshawb fawb thiab thev naus laus zis tshiab ib puag ncig tiv thaiv lub tsev khoom siv-polyurethane (PU) xim steel sandwich vaj huam sib luag, uas yog npau suav ntawm architects, designers thiab engineers.
1. Rigid polyurethane muaj noo noo-pov thawj thiab waterproof.Qhov kaw ntawm tes ntawm nruj polyurethane yog siab dua 90%, uas yog cov khoom siv hydrophobic thiab yuav tsis ua kom cov thermal conductivity vim qhov nqus dej noo, thiab cov phab ntsa saum npoo yuav tsis pom dej.
2. Zoo polyurethane muaj thermal conductivity tsawg thiab thermal ua haujlwm zoo.Thaum qhov ntom ntom ntawm polyurethane yog 38 ~ 42kg / m3, thermal conductivity tsuas yog 0.018 ~ 0.024w / (mk), uas yog ib nrab ntawm EPS, thiab yog qhov qis tshaj ntawm tag nrho cov thermal rwb thaiv tsev cov ntaub ntawv tam sim no.
3. Vim hais tias cov polyurethane sandwich phaj muaj kev ua tau zoo ntawm rwb thaiv tsev, nyob rau hauv tib lub tshav kub uas yuav tsum tau preservation, nws yuav txo tau lub thickness ntawm lub tsev lub hnab ntawv qauv, yog li ua rau lub sab hauv tsev siv cheeb tsam.
4. Tsawg tus nqi ua tau zoo.Txawm hais tias chav tsev tus nqi ntawm polyurethane ua npuas ncauj yog siab dua li ntawm lwm cov khoom siv rwb thaiv tsev, tus nqi nce yuav raug txo los ntawm kev txo nqi cua sov thiab cua txias.
