Sechinyakare chisimbiso cherabha chigadzirwa, rabha yekuisa chisimbiso mhete inoda kuve neyakanaka elasticity, simba, yakakwirira kupfeka kuramba, kusimba kusimba uye kureba panguva yekuzorora.Zviratidzo izvi zvine zvinodiwa zvikuru uye zvinogona kushandiswa kugadzira zvisimbiso zverabha zvinoshanda munzvimbo dzisina mafuta uye dzisingapisi kubva -20 ° C kusvika 100 ° C.Pakati pavo, kupikisa kupfeka kunobata zvakananga hupenyu hwebasa remhete yekuisa chisimbiso uye chisimbiso chekuita.Saka nzira yekuenderera mberi nekuvandudza kupfeka kuramba kweiyo rubber yekuisa chisimbiso mhete mukugadzirwa chaiko?
1. Wedzera kuoma kwerabha zvakakodzera
Muchidzidzo, kuwedzera kuoma kwerabha kunogona kuwedzera kuramba kwerabha kune deformation.Iyo rubber sealing ring uye iyo yekubata kumeso inogona kubatwa zvakaenzana pasi pechiito chekushushikana, nekudaro ichivandudza kupfeka kuramba.Kazhinji, vazhinji vanogadzira rabha yekuisa chisimbiso mhete vanowanzo wedzera iyo sulfur yemukati kana kuwedzera imwe huwandu hwesimba mumiriri kuvandudza kuoma kwerabha.
Izvo zvinofanirwa kucherechedzwa kuti kuoma kweiyo rubber sealing ring haifanire kunge yakanyanya kukwirira, kana zvisina kudaro ichakanganisa elasticity uye cushioning mhedzisiro yemhete yekuisa chisimbiso, uye pakupedzisira inotungamirira mukuderera kwekupfeka kusagadzikana.
2. Gadzirisa elasticity yerabha
Kuti uderedze mutengo wezvigadzirwa zverabha, vagadziri vezvigadzirwa zverabha vanozadza huwandu hukuru hwekuzadza rubha, asi yakawandisa rubber filler inoderedza kusimba kwerabha.Izvo zvinodikanwa kudzora zvine musoro dosi, kunyatso wedzera elasticity yerabha, kuderedza viscosity uye hysteresis yerabha, uye kuderedza coefficient of friction kuvandudza kupfeka kuramba kwerabha zvisimbiso.
3. Gadzirisa dhigirii yevulcanization
Zvinoenderana nehunhu hwekuita kwerabha vulcanization kuita, vagadziri vezvigadzirwa zverabha zvinonzwisisika vanogadzirisa vulcanization system uye vulcanization paramita yezvisimbiso zverabha kuti iwedzere dhigirii revulcanization uye nekuvandudza kupfeka kuramba kwezvisimbiso zverabha.
4. Kuvandudza kusimba kwekusimba kwerabha
Kana rabha richishandiswa kugadzira zvindori zvekuisa chisimbiso cherabha, kushandiswa kweakapfava particle rubber fillers mukugadzira kunogona kuwedzera simba re intermolecular nekuvandudza kusimba kwekusimba uye kusimba kwekushushikana kwerabha, uye kusvika kumwero wakati kunatsiridza kupfekedzwa kwerabha.
5. Deredza kuputika kwepamusoro kwepamusoro pemhete yekuvhara rubber
Kuwedzera zvinhu zvakadai se molybdenum disulfide uye chidimbu chiduku che graphite kune fomu ye rubber sealing ring inogona kuderedza friction coefficient ye rubber sealing ring uye kunatsiridza kupfeka kwekudzivirira kwemhete yekuisa chisimbiso.Kana vagadziri vezvigadzirwa zverabha vachishandisa rabha kugadzira zvindori zvekuvhara rabha, vanogona kushandisa rabha yakadzokororwa kudzikisa mutengo wezvigadzirwa zvezvigadzirwa zverabha uye kudzivirira dambudziko rekusimba kwemechani uye kupfeka kuramba kwerabha kunokonzerwa nekuwanda kwemafirita erabha.Dhizaini inonzwisisika yerabha yekuisa chisimbiso mhete fomula, kugadziridzwa kwakaringana kwevulcanization process paramita, uye kusarudzwa kweakakodzera uye yakanakisa rabha zvigadzirwa hazvigone chete kuderedza mutengo werabha yekuisa chisimbiso mhete zvigadzirwa, asi zvakare kunatsiridza kupfeka kuramba kwerubha chisimbiso mhete.
