Polyurethane ua npuas ncauj yog lub siab molecular polymer.Ib yam khoom tsim los ntawm polyurethane thiab polyether uas tau muab kev sib xyaw ua ke.Txog tam sim no, muaj ob homhloov tau ua npuas ncauj thiabnruj ua npuas ncauj ntawm kev ua lag luam.Ntawm lawv, cov ua npuas ncauj nruj yog ib kaw-cellqauv, thaum lubhloov tau foam yog ibqhib-cell qauv.Cov qauv sib txawv muaj qhov sib txawv ntawm daim ntawv thov.
TNws ua haujlwm ntawm polyurethane ua npuas ncauj
Polyurethane ua npuas ncauj tuaj yeem ua lub luag haujlwm buffering.Txawm nws yognruj foam lubhloov tau ua npuas ncauj, cov khoom yog zoo thiab tuaj yeem buffered.Tau kawg, nws tuaj yeem muaj ib qhosuab rwb thaiv tsev effect, thiab nws tuaj yeem siv rau hauv qee qhov chaw kom cais qee lub suab zoo heev.Tsawg thermal conductivity thiab zoo thermal rwb thaiv tsev ua haujlwm.Nyob rau hauv nruj ua npuas ncauj ntawm polyurethane ua npuas ncauj, muaj ib yam khoom nrogthermal rwb thaiv tsev thiabwaterproof muaj nuj nqi, uas txo cov thermal conductivity.Hauv qee qhov chaw, qhov no yuav tsum muaj cov thermal conductivity tsawg cua tshuab, thiab lwm yam adhesives yeej tsis haum rau kev siv.
Covdaim ntawv thov ntawm polyurethane ua npuas ncauj
Kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.Raws li kev muab tub lim, qhov sib txawv tuaj yeem ua tiav tag nrho, thiab kev ua haujlwm nplaum tuaj yeem ua tiav.Tom qab kho, nws tuaj yeem lo khov kho thiab muaj lub neej ua haujlwm ntev.
Compression thiab shockproof.Thaum cov polyurethane ua npuas ncauj tau kho tag nrho, yuav tsis tawg, corrosion thiab tev.Nws muaj ntau yam kev siv thiab ntau yam kev siv.Nws tuaj yeem siv rau hauv lub zog tshiab, kev lag luam tub rog, kev kho mob, aviation, nkoj, hluav taws xob, tsheb, cov twj paj nruag, cov khoom siv hluav taws xob, kev kub ceev tsheb ciav hlau, thiab lwm yam, nrog rau cov khoom siv hluav taws xob tsawg, cov cua sov zoo, thiab kev txuag hluav taws xob.Siv hauv hluav taws xob, hluav taws xob thiab lwm yam kev lag luam, nws tuaj yeem tiv taus qhov kub thiab txias ib puag ncig thiab ua haujlwm thermal rwb thaiv tsev.
Soundproofing thiab insulating.Thaum polyurethane ua npuas ncauj yog kho kom zoo, nws tuaj yeem ua kom tsis muaj dej tsis zoo thiab tsis muaj dej.Txawm nyob rau hauv ib qho chaw tsaus thiab ntub, yuav tsis muaj teeb meem.
Tej teeb meem thiab kev tiv thaiv ntawm polyurethane ua npuas ncauj
