1. Dab tsi yog kev txhaj tshuaj pwm qis siab
Cov txheej txheem txhaj tshuaj pwm qis qis yog cov txheej txheem ntim khoom uas siv lub siab txhaj tshuaj qis heev (0.15-4MPa) los txhaj cov khoom kub-yaj rau hauv pwm thiab ua kom nws khov sai. Kub, tiv taus kev cuam tshuam, txo kev co, tiv taus dej noo, tiv taus dej, tiv taus plua plav, tiv taus tshuaj lom neeg thiab lwm yam haujlwm, ua lub luag haujlwm zoo hauv kev tiv thaiv cov khoom siv hluav taws xob.
2. Cov txheej txheem molding thiab daim ntawv thov
Muab daim tawv nqaij rau hauv pwm ua ntej, thiab tom qab ntawd siv lub zog ntawm lub hau ntswj los txhaj cov yas yas uas yaj rau hauv qhov pwm kaw, thiab tom qab ntawd khov thiab ua kom cov khoom kom tau txais cov khoom. Tam sim no, cov txheej txheem no tau siv dav hauv kev tsim cov khoom tiv thaiv qhov rooj tsheb, cov khoom tiv thaiv ncej thiab cov khoom tiv thaiv txee.
3. Cov txiaj ntsig
①Tsis muaj peev xwm poob
② Zoo rau ib puag ncig
③Tsis tas yuav muaj txheej txheej thib ob ntxiv los txhim kho kev ua haujlwm ntau lawm.
④ Tiv thaiv cov khoom sab hauv kom zoo thiab muaj tus nqi tsis lees paub qis.
