Tese tinosangana nechimwe chigadzirwa chakasvibiswa mubasa redu remazuva ese, senge latex zvigadzirwa zvinoshanduka zvichena kana zvachengetwa pakamuri yekupisa, uye silicone yekudziya tambo waya inoshanduka yero pakupisa kwakanyanya.
Sezvakangoitasilicone kupisa tambo wayaiyo yatinowanzo shandisa muhupenyu hwedu, yakashanduka yero mushure mekuiswa pane yakanyanya tembiricha ye200 ℃ kwe4 maawa.Chii chiri kuitika?
Dambudziko iri rinogona kugadziriswa nekushandisa silicone yakakwira anti-yellowing vulcanizer C-15.Kazhinji, zvigadzirwa zvegiredhi rekudya zvine ichi chinodiwa.
Kuti udzivise kutsvuka nekuda kwekuwedzera sulfur, anti-yellowing catalyst + anti-yellowing agent inofanirwa kushandiswa.Ose ari maviri akakosha zvikuru.
Nekudaro, zvinhu zviviri izvi zvinoita kuti inamire zvishoma panguva yekugadzirwa kwemafuta, chiri chinhu chekuteerera.
Wedzera 2-3 zviuru zvehydrogen-ine silicone mafuta maererano nehuwandu hwesilicone.High hydrogen-ine silicone mafuta inogona kugadzirisa dambudziko reyero, asi chigadzirwa chinogona kunge chiri brittle uye chinonamira.
Iwe unogona kupfapfaidza chidimbu chemafuta esilicone pane mold kugadzirisa dambudziko rekudzikisa.Mukuwedzera, chete platinum zambuko rinogona kushandiswa.
Vagadziri vanoongorora kuti kushandisa anti-yellowing agents uye anti-yellowing vulcanizer ipfungwa yakanaka, asi iwe unofanirwawo kutarisisa kuti iyo silicone yekudziya waya yauri kushandisa yakanaka.
Iwe haugone kuwedzera yakawandisa mold kuburitsa agent, zinc stearate, saka unofanirwa kutaurirana nemutengesi kuti uone kana paine yatove nehydrogen silicone mafuta mairi kupa anti-yellowing maitiro.
Upfu hunokosha zvikuru.Kana iyo iron yakawandisa, inoshanduka yero.Kana iwe usingazive kuti yakawanda sei yekuwedzera, unogona kutanga waenzanisa yakajairwa vulcanizer (isina anti-yellowing agent) ne vulcanizer ine anti-yellowing agent.
Chenjerera kuti usawedzera zinc stearate mold release agent.Kana zvikaramba kushanda, zvinokurudzirwa kuti ushandise imwe musanganiswa werabha kana kushandisa platinum vulcanizer.
Kana paine sarufa kana sarufa inotakura mumhoteredzo (senge sulfur-vulcanized zvigadzirwa zvichangobva kubikwa muchoto kechipiri), zvinokonzeresa kuti silicone yekudziya waya chigadzirwa kushanduka yero.
Ndapota inzwa wakasununguka kutibata nesu kuti uwane rumwe ruzivo nezve silicone inodziya tambo waya.
