Kev cai Cam khwb cia polyurethane roj hmab ntawv PU ntawv
Taw qhia
Polyurethane, feem ntau yog cov khoom sib xyaw tshiab ntawm cov yas thiab roj hmab, yog tsim los tom qab tshuaj lom neeg cov tshuaj tiv thaiv ntawm polymer polyalcohol thiab isocyanate los ntawm cov saw txuas ntxiv thiab kev sib txuas. Nws tau muab faib ua polyether thiab polyester raws li nws cov hlua caj dab..
