Cov Roj Hmab Ua Kua-Random Carboxy Nitrile Butadiene Roj Hmab (L-XNBR)
Cov Khoom thiab Kev Siv
L-XNBR yog cov roj hmab ua kua uas muaj cov pab pawg nitrile thiab carboxyl hauv cov saw hlau tseem ceeb. Pab pawg nitrile tuaj yeem muab cov kuab tshuaj zoo, cua sov, kev sib txhuam thiab cov khoom nplaum, thaum pab pawg carboxyl tuaj yeem cuam tshuam nrog epoxy thiab amino pab pawg rau kev kho.
Nws tuaj yeem siv los ua cov khoom siv hloov kho rau epoxy thiab phenolic resins nrog rau tus neeg sawv cev mos rau roj hmab plasticizing, thiab siv rau hauv cov teb ntawm cov menyuam luam ntawv, cov ntsaws ruaj ruaj, cov txheej txheem thiab cov nplaum.
