Mukugadzirisa uye kugadzira zvigadzirwa zvesilica gel, kuitira kupfupisa nguva yekutenderera zvakanyanya sezvinobvira, kune peroxide silica gel, unogona kusarudza yakakwira vulcanization tembiricha.Zvinoenderana neakasiyana madziro ukobvu hwezvigadzirwa zvesilicone, tembiricha yekuumbwa inowanzosarudzwa pakati pe180 ℃ ne230ºC.Nekudaro, pane kazhinji kune mamwe matambudziko ane minzwa mukugadzirisa uye kugadzirwa kwe silica gel zvigadzirwa.Izvo zvinodikanwa kubhadhara kune zvinotevera pfungwa.
(1) Kana tembiricha yakawandisa, pachave nekutsemuka kwakatenderedza nzvimbo yekuparadzana, kunyanya kune workpiece ine ukobvu hombe.Izvi zvinokonzerwa nekunyanya kushushikana kwemukati kunokonzerwa nekuwedzera mune vulcanization process.Muchiitiko ichi, kutonhora kwemuumbi kunofanira kuderedzwa.Tembiricha yejojo jekiseni inofanira kuiswa pa80 ℃ kusvika 100 ℃.Kana iwe uchigadzira zvikamu zvine nguva yakareba yekurapa kana nguva yekutenderera, tembiricha iyi inofanirwa kudzikiswa zvishoma.
(2) Kune platinized silica gel, zvinokurudzirwa kushandisa yakaderera tembiricha.Kazhinji, tembiricha yejojo jekiseni haipfuure 60 ℃.
(3) Kuenzaniswa neyakasikwa rabha, yakasimba silica gel inogona kuzadza iyo mold cavity nekukurumidza.Nekudaro, kuti udzivise uye uderedze kuumbwa kwemhepo mabhuru uye kumwe kusvibiswa, kukurumidza kwejekiseni kunofanirwa kuderedzwa.Kumanikidza kuchengetedza maitiro kunofanirwa kuiswa kwenguva pfupi uye kudzvinyirira kudiki.Kunyanya kukwira kana kurebesa kudzvanywa kunoburitsa notch yekudzoka kutenderedza gedhi.
(4) peroxide vulcanization system yesilicone rubber, nguva yevulcanization yakaenzana nefluorine rubber kana EPM, uye ye platinized silica gel, nguva yevulcanization yakakwirira uye inogona kuderedzwa ne70%.
(5) Kuburitsa mumiririri ane silica gel inorambidzwa zvachose.Zvikasadaro, kunyangwe kushomeka kwesilica gel kusvibiswa kunotungamira mukuitika kwekunamira kwe mold.
