Yog polyurethane lom?

Polyurethane nws tus kheej yog tsis-lom, tab sis tsis muaj cov khoom siv tau 100the synthes, catalalants, cov neeg sawv cev, cov neeg sawv cev ua npuas dej, ua haujlwm ntxiv
1. Polyols thiab Isocyanates feem ntau muaj kev cuam tshuam kom ua kom tiav los ua cov khoom siv polymer, uas tsis muaj kev hloov khoom tsis muaj qhov chaw tsis txaus.
2. Tsau thiab catalysts tsis koom nrog cov tshuaj tiv thaiv, thiab yuav nyob twj ywm hauv chav kub, tab sis lub tsheb tshiab muaj qhov tsis hnov ​​tsw heev tom qab raug lub hnub. Muaj twb muaj refactive surfactants thiab catalysts, uas hnov ​​tau rau hauv polymer saw thiab yuav tsis pub dawb.
3. Tus neeg sawv cev ua npuas ncauj tau muab faib ua cov tsiaj txhu ua npuas ncauj thiab ua npuas dej ua npuas ncauj tsim cov pa roj carbon dioxide thiab tsis muaj ntxhiab; Tus neeg sawv cev cev nqaij daim tawv yog cov tshuaj npau taws (uas hloov pauv ntawm cov neeg ua haujlwm ntau dua, tab sis cov tshuaj no tau tshwm sim thaum lawv tuaj txog ntawm tus neeg siv.4. Ib qho ntxiv, yog tias cov ntaub ntawv raw yog cov khoom tsis zoo thiab qis kawg nkaus, tus ntxhiab nws yog loj, thiab cov ntxhiab tsw ntawm cov khoom lag luam tsim tawm yog hnyav. Tsis muaj tshuaj lom neeg tuaj yeem lav txog 100% ntaub ntawv kuj muaj cov ntxhiab tsw thiab tshuaj lom neeg, yog li nws yuav tsum siv tom qab tu; Polyurethane cov khoom yuav tsum muaj qhov cua kom ntau li ntau tau thiab siv tom qab cov ntxhiab tsw txawv.
