Cov yam ntxwv ua haujlwm ntawm engineering plastics
(1) Muab piv nrog cov khoom siv dav dav, nws muaj qhov ua tau zoo heev ntawm kev kub thiab txias, thiab muaj cov khoom siv zoo heev hauv qhov kub thiab txias, thiab tsim nyog siv los ua cov khoom siv;
(2) Zoo corrosion kuj, tsis tshua muaj kev cuam tshuam los ntawm ib puag ncig, thiab zoo kav ntev;
(3) Piv nrog cov ntaub ntawv hlau, nws yooj yim rau kev ua, muaj kev ua haujlwm siab, thiab tuaj yeem ua kom yooj yim cov txheej txheem thiab txuag nqi;
(4) Kev ruaj ntseg zoo thiab hluav taws xob rwb thaiv tsev;
(5) Lub teeb yuag, muaj zog tshwj xeeb, thiab zoo heev los tiv thaiv kev sib txhuam thiab hnav tsis kam.
