Ntawm cov ntaub ntawv rwb thaiv tsev peb feem ntau tuaj ntsib nrog tam sim no, lawv feem ntau yog EPS, XPS thiab PU.
EPS yog ib qho thermoplastic nrog qhov zoo ntawm tus nqi qis thiab kev ua haujlwm zoo ntawm cov hluav taws kub, tab sis cov nplaim hluav taws tsis zoo thiab kev ua haujlwm ntawm cov nplaum.
XPS kuj tseem muaj qee qhov kev tiv thaiv thermal. Vim tias cov khoom siv no yog qhov tsim nyog rov siv dua ntawm cov khib nyiab polystyrene, nws kuj yog qhov tsim nyog rau kev tiv thaiv ib puag ncig, nws cov txiaj ntsig zoo yog cov nqi dav dav, kev ua haujlwm zoo dej tsis zoo, lub zog siab, ruaj khov molding, thiab txawm tias yog cov khoom siv dav hlau khiav, nyob rau hauv xyoo tas los no dav siv. nyob rau hauv thaj tsam ntawm sab nrauv phab ntsa rwb thaiv tsev. Nws qhov tsis zoo yog kev ua haujlwm tsis zoo ntawm cov nplaum thiab kev ua haujlwm ntawm cov hluav taws xob hluav taws xob.
PU yog hais txog polyurethane ua npuas ncauj, feem ntau nyob rau hauv lub tsev rwb thaiv tsev feem ntau yog hais txog nruj ua npuas ncauj. Polyurethane txhav ua npuas ncauj yog qhov tam sim no thoob ntiaj teb kev ua tau zoo ntawm cov khoom siv rwb thaiv tsev, tag nrho cov kev ntsuas kev ua tau zoo dua li XPS cov tsoos, thiab EPS, tsis tsuas yog cov rwb thaiv tsev zoo, muaj zog sib txuas, thiab yooj yim mus tas li ntau lawm, molding kev zoo nkauj tam sim no, tab sis qhov tsis zoo yog qhov siab. nqi.
