Irabha kanye ne-polyurethane kokubili kuyizinto ezivamile zezimboni, futhi zombili izingxenye eziyisisekelo ezisetshenziselwa ukwenza izinto zokunyathela isondo le-caster. Zombili izinto zokwakha zinezinzuzo zazo kanye nokubi, futhi isigaba esilandelayo sihlola umehluko ngokuningiliziwe, kanye nezimo okufanele ukhethe kuzo ukuthi iyiphi impahla.
Ake siqale ngokubheka umehluko obonakalayo phakathi kwerabha ne-polyurethane. Irabha ingxenye eyindilinga eyenziwe ngezinto zenjoloba ezivumelana nezimo futhi ezingasheleli. Irabha ihlukaniswa ngokuyinhloko ibe irabha yemvelo kanye nerabha yokwenziwa, futhi ingalungiselelwa ubulukhuni nokumelana nemihuzuko njengoba kudingeka. I-polyurethane ivamise ukuba nzima futhi imelana kakhulu nokuhuzuka kunama-casters erabha. Ama-polyurethane casters ngokuvamile enziwa ngama-polyurethane elastomers, anobukhulu obuphezulu nobulukhuni.
Okwesibili, ama-rubber casters nama-polyurethane casters enza ngokuhlukile ezimeni ezahlukene. Ama-rubber casters enza kahle ngokwemibandela yokuguquguquka, ukumelana nokushelela kanye nokufakwa komsindo, futhi ashibhile futhi kulula ukuwacubungula kanye nokwenza. Ngakho-ke, ama-rubber casters ayisinqumo esingcono ezimweni lapho kudingeka khona ukuguquguquka nokushaqeka, njengasemishini yezokwelapha, ifenisha, imishini kagesi kanye nemishini yezemidlalo. Ngakolunye uhlangothi, ama-polyurethane casters enza kangcono ngokuphathelene nobunzima, ukumelana nokuhuzuka, namandla okuthwala umthwalo, ngakho afaneleka kakhulu ezimweni zezimboni, zokukhiqiza, nezokwakha lapho ukuthwala isisindo kuyadingeka.
Lezi zinhlobo ezimbili zama-casters nazo zihlukile mayelana nokuvikelwa kwemvelo. Ama-rubber casters adinga ukusetshenziswa kwamakhemikhali enqubweni yokukhiqiza, njengama-agent e-vulcanizing nama-accelerator, angase angcolise imvelo. Ngakolunye uhlangothi, ama-polyurethane casters ahambisana kakhulu nemvelo njengoba eyimpahla egaywa kabusha futhi akhiqiza imfucuza encane ngesikhathi sokukhiqiza.
Okokugcina, ngokwenani, ama-caster enjoloba ashibhile kuyilapho ama-polyurethane caster ebiza kakhulu. Lokhu kungenxa yokuthi izinto ze-polyurethane zibiza kakhulu futhi zinzima kakhulu ukuzicubungula, ngakho-ke ama-polyurethane casters abiza kakhulu. Izinto zenjoloba, ngakolunye uhlangothi, zibiza kancane futhi inqubo yokukhiqiza ilula, ngakho-ke ama-rubber casters ashibhile.
Ngakho-ke, lapho ukhetha ama-rubber casters kanye ne-polyurethane casters, kufanele ukhethe kanjani?
Eqinisweni, bobabili banezinzuzo zabo kanye nokubi, futhi ukukhetha okuqondile kufanele kuncike esimweni. Uma udinga izinto ezinwebekayo, ezimelene nokushelela kanye nezinto ezibamba ukushaqeka, njengefenisha, izinto zikagesi kanye nemishini yezemidlalo, kufanele ukhethe ama-casters erabha. Uma udinga ama-casters anesisindo esikhulu somthamo kanye nokumelana nokuhuzuka, njengasembonini, ekukhiqizeni nasekwakhiweni, kufanele ukhethe ama-polyurethane casters.
Ngaphandle kwama-rubber casters nama-polyurethane casters, kunezinye izinhlobo ze-caster ezifana ne-nylon caster kanye ne-PP casters. Uhlobo ngalunye lwe-caster lunezinzuzo zalo kanye nokubi futhi kufanele lukhethwe ngokuvumelana nezidingo zangempela. Ngaphezu kwalokho, lapho ukhetha lawa ma-casters, kufanele unake kakhulu ubukhulu bepuleti yensimbi yebakaki, impahla yensimbi yensimbi, ngezinga elikhulu, inquma umthamo wokuthwala nokuphepha kwama-casters, akufanele kunganakwa, zama. ukukhetha uhlobo lwensimbi ye-manganese yezinto ze-caster, ikhwalithi nokuthembeka kwayo ephakeme kakhulu kunensimbi evamile.
Yiqiniso, kufanele futhi sinake ubukhulu casters nge ukufakwa, ukuqinisekisa ukufakwa bushelelezi, ukuze ukusebenza kwayo evamile.
