PU Kev Nyab Xeeb Cov Khaub Ncaws Pob Zog
PU Kev Nyab Xeeb Cov Khaub Ncaws Pob Zog
INtroduction
PU Kev Nyab Xeeb Cov Khaub Ncaws Hnav yog siv los ua cov khau kev nyab xeeb thiab sab hauv. Nws yog polyester-based-based pU system cov khoom, muaj plaub feem, polyol, ISO, Hardner thiab catalyst. Kev ua cov kab ke yog ob feem ntawm. Cov catalyst, nyuaj, tshuab tus neeg sawv cev thiab cov xim yog xim kom huv si nrog polyol tiv thaiv nrog iso tivthaiv exd-3119b rau kev ua tsov rog kawg.
