Hunhu hwesilicone yekuwedzera molds
1. Kuwedzera rudzi silica gel inhengo mbiri AB.Paunenge uchiishandisa, sanganisa iwo maviri muhuremu hwe1: 1 uye simbisa zvakaenzana.Zvinotora 30 maminetsi ekushanda nguva uye 2 maawa ekurapa nguva.Inogona kubviswa mushure memaawa masere.Shandisa mold, kana kuisa muchoto wopisa kusvika ku100 degrees Celsius kwemaminitsi gumi kuti upedze kupora.
2. Kuoma kwakakamurwa kuva sub-zero super-soft silica gel uye 0A-60A mold silica gel, iyo ine zvakanakira zvekugara kwenguva refu isina-discoloration uye yakanaka elasticity.
3. Iyo yakajairika tembiricha viscosity yekuwedzera-mhando silica gel inosvika zviuru gumi, iyo yakanyanya kutetepa kupfuura condensation-mhando silica gel, saka inogona kushandiswa seyakabikwa yekuumba jekiseni.
4. Kuwedzera rudzi silica gel inonziwo platinum inoporesa silica gel.Iri rudzi rwesilicone raw material rinoshandisa platinamu seinokonzeresa mukuita kwepolymerization.Haibudisi chero zvigadzirwa zvekuora.Haina kunhuwa uye inoshandiswa zvakanyanya mukugadzira zvipfuyo zvekudya uye zvigadzirwa zvepabonde zvevanhu vakuru.Icho chinhu chine chepamusoro chekuchengetedza nharaunda pakati pesilica gels.
5. Addition-type silica gel imvura inopenya, uye mavara ane mavara anogona kusanganiswa nemamiriro ekunze ane ushamwari hwemavara paste.
6. Silicone yekuwedzera inogona kuporeswa pakupisa kwekamuri kana kupisa kuti ikurumidze kupora.Kuchengetedza kwezuva nezuva kunogona kumira tembiricha yakaderera ye -60 ° C uye yakakwirira tembiricha ye350 ° C pasina kukanganisa hunhu hwechikafu-giredhi inoenderana nesilicone.
LSR 1: 1 silicone mold kugadzira kuraira kwekushanda
1. Kuchenesa mienzaniso nekugadzirisa
2. Ita chigadziro chakagadziriswa chemuenzaniso uye uzadze gaka nepfuti inopisa yakanyunguduka
3. Spray molding agent yemuenzaniso kudzivirira kunamatira
4. Kunyatso kusanganisa uye kumutsa iyo A uye B maererano nehuwandu hwehuremu hwe1: 1 (simbisa mune imwe nzira kudzivirira kupinda mumhepo yakawandisa)
5. Isa silicone yakavhenganiswa mubhokisi rekutsvaira uye kubudisa mhepo
6. Dururira silicone mubhokisi rakagadziriswa
7. Mushure memaawa 8 ekumirira, kusimbiswa kwapera, zvino kunobvisa muenzaniso
