Silicon Moulding
Kua Silicone Roj Hmab (LSR) yog ob lub cev sib xyaw, qhov twg cov polysiloxane chains tau txhawb nrog kev kho tshwj xeeb. Cov khoom sib xyaw ua ke ib qho muaj cov platinum catalyst thiab cov khoom siv b muaj methylhydrogensiloxane raws li tus ntoo khaub lig-txuas thiab dej cawv. Thawj txoj kev sib txawv ntawm cov roj silicone roj hmab (LSR) thiab cov roj hmab muaj zog sib xws (hcr) yog "kua" ntawm LSR cov ntaub ntawv. Thaum hcr muaj peev xwm siv ib qho peroxide lossis platinum kho cov txheej txheem, LSR siv tsuas yog kho nrog platinum. Vim yog lub thermosetting xwm, kua silicone txhaj tshuaj molding sib xyaw, thaum tswj cov khoom siv ntawm qhov kub thiab tsis muaj kab noj hniav thiab vulcanized.
