Roj Hmab Ua Kua-Hydroxyl Terminated butyronitrile Roj Hmab (HTBN)
Cov Khoom thiab Kev Siv
HTBN yog cov roj hmab nitrile ua kua nrog cov pab pawg hydroxyl ua haujlwm ntawm ob qho kawg ntawm cov saw hlau molecular, nws muaj cov khoom siv lub cev thiab tshuaj zoo ib yam li roj hmab nitrile, thiab nws tuaj yeem kho nrog isocyanate curing agent nrog kev ua haujlwm zoo thiab kev ua haujlwm zoo.
Nws muaj kev tiv taus roj zoo, tiv taus kub, tiv taus kev sib txhuam thiab muaj zog nplaum. Feem ntau siv rau hauv cov nplaum, cov tshuaj pleev xim, cov neeg sawv cev ua kom tawv, tuaj yeem txhim kho qhov tawv, kev nplaum thiab kev ruaj khov ntawm cov khoom sib xyaw, roj thiab tiv taus kub.
