Luv luv Qhia ntawm Polyurethane Ua Npuas Ncauj


Polyurethane ua npuas dej yog cov siab ua cov txheej txheem polymer ua los ntawm isocyanate thiab polyether ua cov khoom siv tseem ceeb, sib xyaw nrog cov khoom siv tshwj xeeb nyob rau hauv kev ua haujlwm ntawm tus neeg ua npuas ncauj, catalyst, nplaim taws rov qab thiab lwm yam tshuaj ntxiv, thiab ua npuas dej rau ntawm qhov chaw los ntawm kev txau-tshuab txau. Cov. Polyurethane ua npuas dej muaj ob hom mos ua npuas dej thiab tawv ua npuas ncauj. Cov dej ua npuas muag yog qhib qauv ntawm tes, thiab cov npuas nyuaj yog cov qauv kaw-cell; Cov npuas dej ua npuas muag tau muab faib ua ob hom: crust thiab non-crust.


Lub ntsiab ua haujlwm ntawm mos mos polyurethane ua npuas yog cushioning. Polyurethane mos ua npuas dej yog feem ntau siv hauv rooj tog zaum hauv rooj tog, hauv ncoo, hauv ncoo, khoom ua si, khaub ncaws thiab lub suab rwb thaiv tsev txheej.


Polyurethane nyuaj ua npuas dej yog ib yam tshiab ntawm cov khoom siv hluavtaws nrog kev ua haujlwm thermal rwb thaiv tsev thiab ua kom dej tsis ua haujlwm. Nws lub thermal conductivity tsawg, tsuas yog 0. 022 ~ 0. 033 W / (m * Κ), uas yog sib npaug ntawm ib nrab ntawm cov yas extruded board. Nws yog qhov qis tshaj thermal conductivity ntawm txhua cov ntaub ntawv rwb thaiv tsev thermal. ntawm. Cov nplaim nplaum polyurethane ua npuas dej tsuas yog siv rau kev rwb thaiv tsev ntawm sab nrauv phab ntsa ntawm cov tuam tsev, kev sib xyaw ntawm cov vuas vov tsev dej thiab lub rwb thaiv tsev, kev rwb thaiv tsev ntawm kev cia khoom txias, lub raj xa hluav taws xob cov khoom siv rwb thaiv tsev, cov laug cam, tsheb thauj khoom thiab cov khoom siv thermal rwb thaiv tsev ntawm txias cia, thiab lwm yam.
