Kwintsimi enkulu yezinto ezisetyenziswa kwi-caster, i-TPU, i-TPE kunye ne-TPR zizinto ezintathu eziye zatsala ingqalelo enkulu. Ngayinye ineempawu zayo zokusebenza ezahlukileyo kwaye zifanelekile kwiimeko ezahlukeneyo zokusetyenziswa. Kubathengi bezinto ezisetyenziswa kwi-caster, kubalulekile ukuqonda iimpawu kunye nobubanzi bokusetyenziswa kwezi zinto.
Izinto zeTPU Caster
Izinto ze-TPU (thermoplastic polyurethane) caster zaziwa ngokuxhathisa kwazo ukurhawuzelela, ukumelana neoyile, ukuthamba kwazo okuphezulu kunye neempawu zokuthwala umthwalo. Ezi mpawu zenza ukuba i-TPU caster compound isetyenziswe kakhulu kumavili emithwalo kunye nee-caster kumashishini amaninzi. Ukuxhathisa kwayo ukurhawuzelela okuphezulu kuthetha ukuba inokugcina ukusebenza okuzinzileyo ixesha elide, inciphisa ukuwohloka kokusebenza ngenxa yokuguguleka kunye nokuphindaphindwa kokutshintshwa. Ukongeza, izinto ze-TPU caster ziyaxokozela xa zisebenza, kodwa oku kubonisa ukuthwala kwayo umthwalo okugqwesileyo kunye nokuzinza. Nangona kunjalo, kufuneka kuqatshelwe ukuba i-TPU ayixhathisi kwi-hydrolysis, ngoko ke ukunxibelelana namanzi ixesha elide kufuneka kuthintelwe ngexesha lokusetyenziswa nokugcinwa.
Izinto ze-TPE caster
I-TPE (thermoplastic elastomer) caster compound idibanisa ukuthamba okuphezulu, amandla kunye nokuqina kwerabha kunye neempawu zokubumba ngenaliti. Oku kwenza ii-TPE caster zibe bhetyebhetye kwaye zisebenze kakuhle kwinkqubo yokuvelisa. Ukongeza, ii-TPE caster zinobuhlobo nokusingqongileyo kwaye azinabungozi, zinombala ogqwesileyo, zichukumisa kamnandi, zimelana nemozulu, zimelana nokudinwa kunye nokumelana nobushushu. Ezi mpawu zenza ukuba izinto ze-TPE caster zisetyenziswe kakhulu kumashishini afana namavili emithwalo kunye namavili etroli. Ukuxhathisa kwayo ukukrweleka okuncinci, ukuthamba kwayo kunye nokufunxwa komothuko kwenza izinto ze-TPE caster zisebenze kakuhle xa zithwaxwa yimithwalo enzima kunye neempembelelo. Kwangaxeshanye, ukusebenza kwengxolo ephantsi kwezinto ze-TPE caster kwenza ukuba ibe zezona zinto zikhethwayo zokulandela indawo ezolileyo. Ukongeza, izinto ze-TPE caster zinokusongwa kwaye zibotshelelwe nge-PP, PE, PC, PS, ABS kunye nezinye izinto ezisisiseko, nto leyo eyandisa iindawo ezisetyenziswa kuzo.
Izinto ze-TPR Caster
I-TPR (i-thermoplastic rubber) caster compound ingathathwa njengohlobo lwe-TPE (kwicandelo le-polystyrene elastomer) ngandlela thile. Isekelwe kwi-SBS kwaye inobuthambile obungcono kune-TPE, kodwa ayixhathisi kakhulu kune-TPE; nangona kunjalo, i-TPR caster compound inobumnene obuhle bokuguguleka, ubuthambile, kunye neempawu zokufunxa ukutshayiswa, okwenza ukuba ifaneleke kwizicelo ezifana nee-casters ezinzima ezithwaxwa yimithwalo enzima kunye neempembelelo. Ukongeza, i-TPR caster compound ibiza kancinci kune-TPE, nto leyo eyinika inzuzo yezoqoqosho. Ngokufanayo ne-TPE, izinto ze-TPR caster zinokugqunywa ngeplastiki eqinileyo efana ne-PA kunye ne-PP, nto leyo eyandisa ukuguquguquka kwayo kokusetyenziswa.
Shwankathela
Izixhobo ze-TPU, TPE kunye ne-TPR caster nganye ineempawu zayo kunye nokusetyenziswa kwayo okwahlukileyo. I-TPU yaziwa ngokuxhathisa kwayo ukurhawuzelelwa, ukumelana neoyile kunye neempawu zokuthwala umthwalo; I-TPE ithandwa ngenxa yokuthamba kwayo okuphezulu, amandla aphezulu kunye nokukwazi kwayo ukubumba ngenaliti; I-TPR inendawo kwicandelo lee-caster ezinzima ngenxa yokuthamba kwayo okuphezulu kunye nexabiso eliphantsi. Xa sikhetha ezi zixhobo ze-caster, kufuneka sigwebe ngokweemeko ezithile zokusetyenziswa kunye neemfuno ukuqinisekisa ukuba izixhobo ezikhethiweyo zinokuhlangabezana neemfuno zethu.
