Kubatanidza silicone rubber molding process

1. Kushandiswa kwekubatanidza silicone rubber teknolojia

Kneading silicone rubber irabha yekugadzira iyo inodzokororwa yakanatswa nekuwedzera raw silicone rabha kune kaviri-roll rabha mixer kana yakavharwa kneader uye zvishoma nezvishoma kuwedzera silica, silicone mafuta, nezvimwewo uye zvimwe zvinowedzera. Inogona kushandiswa zvakanyanya mukubhururuka nendege, tambo, zvemagetsi, midziyo yemagetsi, makemikari, zviridzwa, simende, mota, kuvaka, kugadzira chikafu, midziyo yekurapa uye mamwe maindasitiri, uye inoshandiswa pakadzika kugadzirisa michina senge kuumba uye extrusion.

2. Nzira yekugadzira kusanganisa silicone rubber

Silicone rubber: Kusanganisa silicone rabha inogona kusanganiswa pasina plasticizing. Kazhinji, muvhenganisi wakavhurika unoshandiswa kusanganisa, uye tembiricha yekuyerera haipfuure makumi mashanu madhigirii.

Kusanganiswa kunoitwa mumatanho maviri:

Ndima yekutanga: raw raw-reinforcing agent-structure control agent-heat-resistant additive-thin-pass-low sheet.

Danho rechipiri: danho rekunatsa - vulcanizing agent - thin pass - kupaka. Silicone rubber zvakasiyana zvidimbu.

Yetatu, kusanganisa silicone rubber molding process

1. Kuumba: tanga kubaya rabha mune imwe chimiro, rizadze mugomba rekuumbwa, isa mold pakati pepamusoro uye pasi mahwendefa eheated flat vulcanizer, uye kupisa uye kumanikidza iyo maererano neyakatemerwa maitiro kuti vulcanize rabha. Dzikisa mold kuti uwane chikamu che vulcanized silicone rubber zvigadzirwa

2. Kutamisa kuumbwa: isa rakagadzirirwa rabha zvinhu mu plug cylinder pachikamu chepamusoro che mold, kupisa uye plasticize, uye shandisa kudzvanywa kweplunger kuita kuti rubber zvinhu zvipinde mukati mekupisa mold cavity kuburikidza nemuromo wekuumba.

3. Majekiseni ekuumba: Isai zvinhu zverabha mudhiramu rekudziya nekuisa plasticizing, jekiseni zvinhu zverabha zvakananga mugomba rakavharika nemumuromo nemupumburu kana sikuruu, uye ziva nekukurumidza in-situ vulcanization pasi pekupisa.

4. Extrusion molding: inoenderera mberi yekuumba nzira yekumanikidzira kuburitsa rabha yakasanganiswa kuburikidza nefa kupinda muchigadzirwa chine chimwe chimiro chemuchinjikwa.

Naizvozvo, kana iyo silicone chigadzirwa fekitori ichiona kuumbwa kwesilicone zvigadzirwa, zvinodikanwa kusarudza nzira yakakodzera yekuumba zvinoenderana nechigadzirwa uye nzira yekushandisa. Kana huwandu hwezvigadzirwa zvesilicone rubber yakakura uye yakareruka muhuremu, kutamisa kuumba kunogona kusarudzwa panzvimbo yekusarudza mapofu, izvo zvisingazokonzeri chete kugadzirwa Kusashanda kwakatorawo kukanganisa pafekitari.
