Rubber kugadzira nzira
Rubha chinhu chinotanuka chinowanzo torwa kubva kune latex yemiti yerabha kana yekugadzira masosi. Iyo inoratidza yakanakisa elasticity, abrasion kuramba, uye kuchembera kuramba, ichiita kuti ishandiswe zvakanyanya mumhando dzakasiyana siyana sekugadzira matayi, zvisimbiso, mapaipi, mapedhi erabha, nezvimwe. Maitiro ekugadzira ezvigadzirwa zverabha anowanzo sanganisira akati wandei makiyi ekugadzirisa matanho senge mastication, kusanganisa, calendering, extrusion, kuumba, uye vulcanization. Nhanho imwe neimwe ine basa rakakosha pakuona mashandiro uye kunaka kwezvigadzirwa zvekupedzisira. Pazasi pane rondedzero yakadzama yemaitiro ekugadzira zvigadzirwa zverubha.
1. Mastication:
Iyo rabha yakasvibirira uye zvinowedzera zvinosanganiswa uye zvinopisa murubber crusher kupfavisa rabha, kusimudzira kunamatira, uye kubvisa tsvina irimo.
Zvinhu Zvinokosha: Kudzora nguva, tembiricha, simba remagetsi, uye mhando / zviyero zvemasticating agents.
2. Kusanganisa:
Mumusanganisi, rubber uye zvakasiyana-siyana zvinowedzera (zvakadai sevulcanization agents, anti-aging agents, fillers, nezvimwewo) zvakasanganiswa zvakaenzana kuti zvivandudze kushanda kwezvigadzirwa zverubha.
Zvinhu Zvinokosha: Rudzi, chikamu, uye kutevedzana kwezvinowedzera, kusanganisa tembiricha uye nguva, kusanganisa kusimba, pakati pevamwe.
3. Calendaring:
Iyo yakasanganiswa rabha inotsikirirwa kuita mapepa matete kana mitsetse yakatetepa nemuchina wecalender kuitira kunotevera kugadzirisa nekuumbwa.
Zvinhu Zvinokosha: Kudzora tembiricha yekarenda, kumhanya, kudzvanywa, kuoma kwerabha, uye viscosity.
4. Extrusion:
Iyo rabha inokwidziridzwa nemuchina weextrusion kuita mitsara inoenderera yemidziyo ine chaiyo muchinjiko-chikamu chimiro, iyo inoshandiswa kugadzira zvigadzirwa zverabha mumachubhu, tsvimbo kana mamwe maumbirwo akaomarara.
Zvinhu Zvinokosha: Kudzora tembiricha yemuchina weextrusion, kudzvanywa, kumhanya, kufa musoro dhizaini, nezvimwe.
5. Kuumba:
Iyo yerubha zvinhu inoiswa mu mold, uye pasi pechiito chekupisa nekumanikidza, inozadza mhango ye mold uye inowana chimiro chaunoda.
Zvinhu Zvinokosha: Mold dhizaini, tembiricha, kudzvanywa, kutonga nguva, rabha kuzadza huwandu, uye kuyerera zvivakwa.
6. Vulcanization:
Zvigadzirwa zverabha zvakaumbwa zvinoiswa muchoto chevulcanization, uye vulcanization reaction inoitwa pasi peimwe tembiricha, nguva uye kudzvanywa, kuitira kuti mamorekuru erabha asanganiswe, nekudaro anovandudza simba remuchina, kupfeka kuramba uye kuramba kuchembera. rabha.
Zvinhu Zvinokosha: Kudzora tembiricha yevulcanization, nguva, kudzvanywa, mhando / chiyero che vulcanizing agent, uye cross-link density uye chimiro.
Tsananguro yakadzama iri pamusoro inotaridza matanho akakosha ekugadzirisa mukugadzirwa kwezvigadzirwa zverabha, uye nhanho imwe neimwe kushanda kwayo uye kutonga kwakakosha pakuona kunaka uye kuita kwezvigadzirwa zverabha zvekupedzisira.
