Irabha kanye ne-polyurethane kokubili kuyizinto ezivamile zezimboni, futhi kokubili kuyizinto eziyisisekelo ezisetshenziselwa ukwenza izinto zokunyathela amasondo e-caster. Zombili izinto zinezinzuzo nezinkinga zazo, futhi isigaba esilandelayo sihlola umehluko ngokuningiliziwe, kanye nezimo lapho kufanele ukhethe khona ukuthi iyiphi impahla.
Ake siqale ngokubheka umehluko obonakalayo phakathi kwerabha ne-polyurethane. Irabha iyingxenye eyindilinga eyenziwe ngezinto zerabha ezivame ukuguquguquka futhi ezingasheleli. Irabha ihlukaniswe kakhulu ngerabha yemvelo kanye nerabha yokwenziwa, futhi ingalungiswa ukuze ibhekane nokuqina kanye nokumelana nokuguguleka njengoba kudingeka. I-polyurethane ngokuvamile iqinile futhi imelana nokuguguleka kune-casters zerabha. Ama-casters e-polyurethane avame ukwenziwa ngama-elastomer e-polyurethane, anobukhulu kanye nobunzima obukhulu.
Okwesibili, ama-caster enjoloba nama-polyurethane caster asebenza ngendlela ehlukile ezimweni ezahlukene. Ama-caster enjoloba asebenza kahle ngokuguquguqukayo, ukungasheleli kanye nokuvala umsindo, futhi ashibhile futhi kulula ukuwacubungula nokuwenza. Ngakho-ke, ama-caster enjoloba ayisinqumo esingcono ezimweni lapho kudingeka khona ukuguquguquka kanye nokumuncwa kokushaqeka, njengasemishinini yezokwelapha, ifenisha, imishini kagesi kanye nemishini yezemidlalo. Ama-caster e-polyurethane, ngakolunye uhlangothi, asebenza kangcono ngokuqondene nobunzima, ukumelana nokuklwebheka, kanye nomthamo wokuthwala umthwalo, ngakho-ke afaneleka kakhulu ezimweni zezimboni, zokukhiqiza, kanye nezokwakha lapho kudingeka khona ukuthwala isisindo.
Izinhlobo ezimbili zama-caster nazo zihlukile maqondana nokuvikelwa kwemvelo. Ama-caster enjoloba adinga ukusetshenziswa kwamakhemikhali enqubweni yokukhiqiza, njengezinto ezivulcanizing kanye nezisheshisi, ezingangcolisa imvelo. Ama-caster e-polyurethane, ngakolunye uhlangothi, anobungani kakhulu nemvelo njengoba eyinto ephinde isetshenziswe futhi akhiqiza imfucuza encane ngesikhathi senqubo yokukhiqiza.
Okokugcina, ngokwentengo, ama-caster enjoloba ashibhile kakhulu kuyilapho ama-caster e-polyurethane ebiza kakhulu. Lokhu kungenxa yokuthi izinto ze-polyurethane zibiza kakhulu futhi kunzima ukuzicubungula, ngakho-ke ama-caster e-polyurethane abiza kakhulu. Izinto zerabha, ngakolunye uhlangothi, azibizi kakhulu futhi inqubo yokukhiqiza ilula, ngakho-ke ama-caster enjoloba ashibhile kakhulu.
Ngakho-ke, lapho ukhetha ama-caster enjoloba nama-caster e-polyurethane, kufanele ukhethe kanjani?
Eqinisweni, zombili zinezinzuzo nezinkinga zazo, futhi ukukhetha okukhethekile kufanele kuncike esimweni. Uma udinga ukunwebeka, izici ezivimbela ukushelela kanye nezici ezibamba ukushaqeka, njengefenisha, imishini kagesi kanye nemishini yezemidlalo, kufanele ukhethe ama-caster enjoloba. Uma udinga ama-caster anesisindo esikhulu kanye nokumelana nokuklwebheka, njengasezimbonini, ekukhiqizeni nasekukhiqizweni, kufanele ukhethe ama-caster e-polyurethane.
Ngaphandle kwama-caster enjoloba nama-polyurethane caster, kunezinye izinhlobo zama-caster njenge-nylon caster nama-PP caster. Uhlobo ngalunye lwe-caster lunezinzuzo nezinkinga zalo futhi kufanele lukhethwe ngokwezidingo zangempela. Ngaphezu kwalokho, lapho ukhetha la ma-caster, kufanele unake kakhulu ubukhulu bepuleti lensimbi le-bracket, izinto zepuleti lensimbi, ngezinga elikhulu, zinquma amandla okuthwala kanye nokuphepha kwama-caster, akufanele zinganakwa, zama ukukhetha uhlobo lwensimbi ye-manganese ye-caster, ikhwalithi nokuthembeka kwayo okuphezulu kakhulu kunensimbi evamile.
Yiqiniso, kufanele futhi unake ubukhulu be-casters ngokufakwa, ukuqinisekisa ukufakwa okubushelelezi, ukuze ukusebenza kwayo kube okuvamile.
