Hauv kev ua thiab tsim cov khoom siv silica gel, txhawm rau txo lub sijhawm voj voog kom ntau li ntau tau, rau peroxide silica gel, koj tuaj yeem xaiv qhov kub ntawm vulcanization.Raws li cov phab ntsa sib txawv ntawm cov khoom siv silicone, cov pwm kub feem ntau yog xaiv ntawm 180 ℃ thiab 230ºC.Txawm li cas los xij, feem ntau muaj qee qhov teeb meem hauv cov txheej txheem ntawm kev ua thiab tsim cov khoom siv silica gel.Nws yog ib qho tsim nyog yuav tau xyuam xim rau cov ntsiab lus hauv qab no.
(1) Yog tias qhov kub thiab txias dhau lawm, yuav muaj cov kab nrib pleb nyob ib puag ncig ntawm qhov sib cais, tshwj xeeb tshaj yog rau cov khoom siv nrog cov tuab loj.Qhov no yog tshwm sim los ntawm kev ntxhov siab ntau dhau los ntawm kev nthuav dav hauv cov txheej txheem vulcanization.Hauv qhov no, qhov kub ntawm pwm yuav tsum tau qis dua.Qhov kub ntawm chav txhaj tshuaj yuav tsum tau teem rau ntawm 80 ℃ to 100 ℃.Yog tias koj tab tom tsim cov khoom nrog lub sijhawm kho ntev ntev lossis lub sijhawm voj voog, qhov ntsuas kub no yuav tsum tau qis dua me ntsis.
(2) Rau platinized silica gel, nws raug nquahu kom siv qhov kub thiab txias.Feem ntau, qhov kub ntawm chav txhaj tshuaj tsis tshaj 60 ℃.
(3) Muab piv nrog cov roj hmab ntuj, cov khoom siv silica gel tuaj yeem sau cov kab noj hniav sai sai.Txawm li cas los xij, txhawm rau zam thiab txo qhov tsim ntawm huab cua npuas thiab lwm yam impurities, kev txhaj tshuaj nrawm yuav tsum raug txo.Cov txheej txheem tuav lub siab yuav tsum tau teem caij rau lub sijhawm luv luv thiab lub siab me me.Siab dhau los yog ntev dhau los tuav yuav ua rau rov qab los ntawm lub rooj vag.
(4) peroxide vulcanization system ntawm silicone roj hmab, lub sij hawm vulcanization yog sib npaug rau fluorine roj hmab los yog EPM, thiab rau platinized silica gel, lub sij hawm vulcanization yog siab dua thiab yuav txo tau los ntawm 70%.
(5) Kev tso tawm tus neeg sawv cev uas muaj silica gel raug txwv nruj heev.Txwv tsis pub, txawm me ntsis silica gel paug yuav ua rau tshwm sim ntawm pwm sticking.
