Peb RE yog tus neeg nquag sib txuas tus neeg sawv cev, Siv nyob rau hauv cov nplaum ua los ntawm hydroxyl polyurethane, ntuj los yog hluavtaws roj hmab, nws muaj kev sib raug zoo zoo hauv cov roj hmab thiab cab siv hauv cob, antioxidant, plasticizing tus neeg sawv cev, siab-rhiab thiab lwm yam. tuaj yeem siv ua crosslinker hloov BAYER's Desmodur RE.

Thov

Ob chav ntsej muag nplaum yuav tsum siv nyob rau hauv cov khoom siv tom qab muab tso rau hauv RE. Lub sijhawm siv tau tsis tsuas yog cuam tshuam nrog cov ntsiab lus polymer ntawm cov nplaum, tab sis kuj tseem muaj lwm cov khoom sib txuas (xws li cov khoom tso tawm, antioxygen, yas, cov kuab tshuaj, thiab lwm yam.) Thaum ze rau lub sijhawm siv, feem ntau yog ob peb teev lossis ib hnub ua haujlwm, cov nplaum ua qhov nyuaj dua rau kev khiav lag luam, thiab viscosity nce sai sai. Thaum kawg, Nws tiav niam txiv tsis tuaj yeem ua tau.Qhov zoo 100 lo nplaum, Hydroxyl polyurethane (Polyurethane tus account rau ib ncig 20%), RE koob 4-7. , Peb RE puas yog 4-7.

Lwm Yam Qhia Txog Lwm Yam

Cia:

Thov muab ntim rau hauv lub thawv ntim hauv qab 23 ℃, cov khoom lag luam tuaj yeem khaws cia kom ruaj khov rau 12 lub hlis. Nws rhiab heev rau qhov feem ntau; nws yuav tsim cov pa roj carbon dioxide thiab insoluble urea hauv kev cuam tshuam nrog dej. Yog tias cuam tshuam rau teh huab cua lossis lub teeb ci, nws yuav ceev xim hloov, tab sis cov kev coj ua yuav tsis muaj kev cuam tshuam.
