Thaum tham txog cov ntaub ntawv rwb thaiv tsev thermal, ntau tus neeg yuav xav txog cov khoom siv nrov tam sim no: polyurethane. Tshaj li nws siv hauv thermal rwb thaiv tsev, polyurethane ua haujlwm rau ntau yam kev lag luam thiab sawv tawm raws li cov khoom lag luam hnub qub hauv kev lag luam tshuaj. Raws li ib qho zoo insulator, polyurethane feem ntau yog siv nyob rau hauv ob qho tib si sab hauv thiab sab nrauv lub tsev daim ntaub ntawv, nrog rau lub ru tsev, phab ntsa, pem teb, thiab qab nthab. Hauv kev ua lag luam niaj hnub no, Huntsman yog arguably tus thawj coj hauv cov ntaub ntawv polyurethane; lub tuam txhab yog lub ntiaj teb frontrunner nyob rau hauv muab tshuaj tsuag polyurethane ua npuas ncauj daws rau kev tsim kho kev lag luam. Polyurethane yog qhov ceev tshaj plaws - cov khoom siv rwb thaiv tsev loj hlob thoob ntiaj teb, thiab cov tshuaj tsuag polyurethane ua npuas ncauj tuaj yeem pab txo cov nqi hluav taws xob txog li 50% hauv ob lub tsev tshiab thiab tam sim no. Tsis tas li ntawd, tshuaj tsuag polyurethane ua npuas ncauj ua haujlwm ua ob qho tib si insulator thiab huab cua thaiv, pab txo qis zog los ntawm huab cua infiltration. Huntsman tseem muab cov khoom siv raw rau kev tsim ib qho -cov khoom ua npuas ncauj sealants.
Tab sis dab tsi yog polyester polyol? Ntau tus yuav xav paub txog qhov no. Huntsman tau tshaj tawm cov khoom tshiab polyester polyol hu ua Terol®. Featuring muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov qauv, Terol® ua lub hauv paus rau kev tsim cov ntaub ntawv polyurethane rwb thaiv tsev- xws li cov tshuaj tsuag ua npuas dej thiab cov laug cam - uas muaj kev ua tau zoo. Cov khoom no xa cov khoom zoo ib yam, zoo tshaj thermal rwb thaiv tsev, thiab zoo heev nplaim retardancy. Yog li ntawd, lawv tau dav siv nyob rau hauv cov sectors nrog nruj rwb thaiv tsev thiab hluav taws kev nyab xeeb yuav tsum tau, xws li kev lag luam tsim, txias saw warehousing, thiab niaj hnub ua liaj ua teb. Huntsman tseem ua kom muaj txiaj ntsig zoo ntawm Terol® polyester polyol, siv nws ua cov khoom siv raw rau polyurethane sandwich panels hauv kev lag luam txias saw. Thaum siv hauv tsev siv rwb thaiv tsev, Terol®- cov khoom siv tuaj yeem txhim kho kev ua haujlwm thermal los ntawm ntau dua 50% piv rau cov khoom siv ib txwm muaj xws li polystyrene boards thiab pob zeb ntaub plaub, thaum txo qis kev siv hluav taws xob thiab cov pa roj carbon monoxide. Tsis tas li ntawd, cov ntaub ntawv no tuaj yeem txhawb nqa lub tsev qhov kev nyab xeeb hluav taws rau B1 lossis siab dua, txo qhov kev pheej hmoo ntawm hluav taws kub.
