Njengengxenye ebalulekile yohlu olubanzi lwemishini, ifenisha namathuluzi, impahla kanye nokusebenza kwama-casters kunomthelela omkhulu kwikhwalithi nokusebenza komkhiqizo jikelele. Phakathi kwezinhlobo eziningi zama-casters, i-TPR casters kanye ne-BR rubber casters yizinketho ezimbili ezivamile. Namuhla kuzoba ukuqhathanisa okuningiliziwe komehluko phakathi kwalezi zinhlobo ezimbili zabalingisi be-BR vs. tpr.
Izinto zokwakha kanye nezakhiwo
Okokuqala nje, ama-caster e-TPR enziwe ngenjoloba ye-thermoplastic (TPR), impahla ye-thermoplastic ene-elasticity yenjoloba, engadingi ukuvuthwa futhi inobungani bemvelo, ayinabo ubuthi, futhi inombala ogqamile. Ngenxa yokunwebeka nokumelana nokuhuzuka kwempahla ye-TPR, ama-caster e-TPR ngokuvamile anemihuzuko emihle, ukumelana nowoyela nesimo sezulu.
Ngokuphambene, izingqimba zenjoloba ze-BR zenziwe ngenjoloba ye-butadiene (BR), irabha yokwenziwa eyenziwe nge-polymerization ye-butadiene monomers, isakhiwo sayo samangqamuzana sifana naleso serabha yemvelo.Irabha ye-BR inokunwebeka okuhle, ukumelana nokuhuzuka, ukumelana nokubanda, futhi ukumelana nokuguquguquka.
Ukucubungula nokusebenza
Ukusebenza kokucubungula kwezinto ze-TPR kungcono kunokwerabha, futhi kungacutshungulwa ngemishini evamile yokucubungula i-thermoplastic ngaphandle kokwelashwa okukhethekile kwe-vulcanization. Lokhu kwenza abakhangisi be-TPR basebenze kahle futhi kungabizi kakhulu ukukhiqiza.
Kodwa-ke, ama-rubber casters e-BR ahamba phambili ekusebenzeni okuguquguqukayo, ikakhulukazi emazingeni okushisa aphezulu.Irabha ye-BR inokumelana okuhle kakhulu nokuhuzuka, ukumelana nokubhoboza, nokumelana nezinyembezi okushukumisayo, okuvumela abakhangisi benjoloba be-BR ukuthi balondoloze ukusebenza kahle ezindaweni ezinokhahlo.
Ukuvikelwa kwemvelo nokuphepha
Mayelana nokuvikelwa kwemvelo, impahla ye-TPR inenzuzo: I-TPR iyinto evumelana nemvelo nengenabo ubuthi ethobelana ne-ROHS, REACH namanye amazinga emvelo, futhi ingasetshenziswa kabanzi emishinini yezokwelapha, amathoyizi ezingane nakweminye imikhakha. Ngokuphambene, nakuba irabha ye-BR nayo iyinto evumelana nemvelo, ingase ivinjelwe imithetho yemvelo kwezinye izimo zohlelo lokusebenza.
Lapho kukhethwa ama-casters, ukucatshangelwa okuphelele kufanele kwenziwe ngokusekelwe ezicini ezifana nezimo ezithile zohlelo lokusebenza, izidingo zokusebenza nemithethonqubo yezemvelo. Isibonelo, abakhangisi be-TPR bangase babe ukukhetha okungcono ezimeni ezidinga ukukhiqiza okuphezulu, izindleko eziphansi kanye nezidingo eziphezulu zemvelo, kuyilapho ama-rubber casters e-BR angase afaneleke kakhulu ezimweni zohlelo lokusebenza ezidinga ukusebenza okunamandla okuphezulu kanye nokumelana nokushisa okuphezulu.
