Cov khoom siv raj roj lub raj mis yog tam sim no tsis yog cov khoom tsis muaj qauv, rau cov tub ua lag luam kev lag luam, nws siv sijhawm ntev los kawm. Txhawm rau kom daws tau cov teeb meem no, polyime Machinery tau tua cov khoom siv ntxuav kom ceev rau cov neeg siv khoom siv tau los ntawm cov ntaub ntawv kom nrawm rau cov khoom siv. Peb lub cev dej-txuag tau ua tiav cov txiaj ntsig ntawm kev ntxuav 1 tuj ntawm lub raj mis flakes nrog tsuas yog 1 tuj ntawm kev siv dej. Polytime tshuab muaj zog R & D muaj zog Innizent hauv thev naus laus zis thiab thev naus laus zis, thiab tham txog kev nce qib nrog cov neeg siv khoom.
