Njengengxenye ebalulekile yemishini ehlukahlukene, ifenisha namathuluzi, izinto zokwakha kanye nokusebenza kwama-casters kunomthelela omkhulu kwikhwalithi kanye nokusebenza komkhiqizo wonke. Phakathi kwezinhlobo eziningi zama-casters, ama-casters e-TPR kanye nama-casters erabha e-BR kuyizinketho ezimbili ezivamile. Namuhla kuzoba nokuqhathaniswa okuningiliziwe komehluko phakathi kwalezi zinhlobo ezimbili zama-casters e-BR vs. tpr.
Izinto kanye Nezakhiwo
Okokuqala, ama-TPR casters enziwe ngerabha ye-thermoplastic (TPR), into e-thermoplastic enokuqina kwerabha, engadingi ukuvundiswa futhi inobungani nemvelo, ayinabo ubuthi, futhi inombala ogqamile. Ngenxa yokuqina nokumelana nokuguguleka kwezinto ze-TPR, ama-TPR casters avame ukuba nokumelana okuhle kokuguguleka, uwoyela nesimo sezulu.
Ngokuphambene nalokho, ama-caster erabha e-BR enziwe ngerabha ye-butadiene (BR), irabha yokwenziwa eyenziwe nge-polymerization yama-monomers e-butadiene, anesakhiwo sama-molecule esifana neserabha yemvelo. Irabha ye-BR inokuqina okuhle, ukumelana nokuklwebheka, ukumelana nokubanda, kanye nokumelana nokugoba.
Ukucubungula nokusebenza
Ukusebenza kokucubungula kwezinto ze-TPR kungcono kunokwenjoloba, futhi kungacutshungulwa ngemishini evamile yokucubungula i-thermoplastic ngaphandle kokwelashwa okukhethekile kwe-vulcanization. Lokhu kwenza ama-caster e-TPR asebenze kahle kakhulu futhi angabizi kakhulu ukuwakhiqiza.
Kodwa-ke, ama-caster erabha e-BR asebenza kahle kakhulu, ikakhulukazi emazingeni okushisa aphezulu. Irabha ye-BR inokumelana okuhle kakhulu nokuguguleka, ukumelana nokubhoboza, kanye nokumelana nokudabuka okunamandla, okuvumela ama-caster erabha e-BR ukuthi agcine ukusebenza okuhle ezindaweni ezinzima.
Ukuvikelwa nokuphepha kwemvelo
Ngokuphathelene nokuvikelwa kwemvelo, izinto ze-TPR zinenzuzo: I-TPR iyinto enobungani nemvelo futhi engenabo ubuthi ehambisana nezindinganiso ze-ROHS, REACH kanye nezinye izindinganiso zemvelo, futhi ingasetshenziswa kabanzi kumadivayisi ezokwelapha, amathoyizi ezingane kanye neminye imikhakha. Ngokuphambene nalokho, yize irabha ye-BR nayo iyinto enobungani nemvelo, ingase ivinjelwe yimithetho yezemvelo ezimweni ezithile zokusetshenziswa.
Uma ukhetha ama-caster, kudingeka kucatshangelwe kabanzi ngokusekelwe ezicini ezifana nezimo ezithile zokusetshenziswa, izidingo zokusebenza kanye nemithethonqubo yezemvelo. Isibonelo, ama-caster e-TPR angaba yisinqumo esingcono ezimweni ezidinga umkhiqizo ophezulu, izindleko eziphansi kanye nezidingo eziphezulu zezemvelo, kuyilapho ama-caster erabha e-BR angase afaneleke kakhulu ezimweni zokusetshenziswa ezidinga ukusebenza okuphezulu okuguquguqukayo kanye nokumelana nokushisa okuphezulu.
