Emkhakheni omkhulu wezinto zokwenziwa kwe-caster, i-TPU, i-TPE kanye ne-TPR kunezinto ezintathu ezidonse ukunaka okukhulu. Ngayinye inezici zokusebenza ezihlukile futhi ifanele izimo ezahlukene zokusetshenziswa. Kubathengi bezinto zokwenziwa kwe-caster, kubalulekile ukuqonda izici kanye nobubanzi bokusetshenziswa kwalezi zinto.
Izinto ze-TPU Caster
Izinto ze-TPU (thermoplastic polyurethane) caster zaziwa ngokumelana kwazo okuhle kakhulu nokuklwebheka, ukumelana namafutha, ukuguquguquka okuhle kakhulu kanye nezakhiwo zokuthwala umthwalo. Lezi zakhiwo zenza i-TPU caster compound isetshenziswe kabanzi kumasondo emithwalo kanye nama-caster ezimbonini eziningi. Ukumelana kwayo okuphezulu kokuklwebheka kusho ukuthi ingagcina ukusebenza okuzinzile isikhathi eside, inciphise ukuwohloka kokusebenza ngenxa yokuguguleka kanye nokuvama kokushintshwa. Ngaphezu kwalokho, izinto ze-TPU caster zinomsindo lapho zisebenza, kodwa lokhu kubonisa ukuthwala kwayo umthwalo okuhle kakhulu kanye nokuqina. Kodwa-ke, kufanele kuqashelwe ukuthi i-TPU ayimelani ne-hydrolysis, ngakho-ke ukuxhumana isikhathi eside namanzi kufanele kugwenywe ngesikhathi sokusetshenziswa nokugcinwa.
Izinto ze-TPE caster
I-TPE (thermoplastic elastomer) caster compound ihlanganisa ukuqina okuphezulu, amandla kanye nokuqina kwerabha kanye nezici zokubumba ngomjovo. Lokhu kwenza ama-TPE caster aguquguquke futhi asebenze kahle enqubweni yokukhiqiza. Ngaphezu kwalokho, ama-TPE caster anobungane nemvelo futhi awanobuthi, anombala omuhle kakhulu, ukuthinta okuthambile, ukumelana nesimo sezulu, ukumelana nokukhathala kanye nokumelana nokushisa. Lezi zici zenza izinto ze-TPE caster zisetshenziswe kabanzi ezimbonini ezifana namasondo emithwalo namasondo etroli. Ukumelana kwayo nokuklwebheka okuhle, ukuqina kwayo kanye nokumuncwa kokushaqeka kwenza izinto ze-TPE caster zisebenze kahle lapho zithwalwa imithwalo esindayo kanye nokushayisana. Ngesikhathi esifanayo, ukusebenza komsindo ophansi kwezinto ze-TPE caster kwenza kube yinto ekhethwayo yokulandela indawo ethule. Ngaphezu kwalokho, izinto ze-TPE caster zingasongwa futhi ziboshwe nge-PP, PE, PC, PS, ABS nezinye izinto eziyisisekelo, kwandise izindawo zayo zokusetshenziswa.
Izinto ze-TPR Caster
I-TPR (i-thermoplastic rubber) caster compound ingabhekwa njengohlobo lwe-TPE (emkhakheni we-polystyrene elastomer) ngandlela thile. Isekelwe ku-SBS futhi inokuqina okungcono kune-TPE, kodwa ayimelani nokuguguleka kancane kune-TPE; noma kunjalo, i-TPR caster compound inokumelana nokuguguleka okuhle kakhulu, ukuqina, kanye nezakhiwo zokumunca ukushaqeka, okwenza ifaneleke ezinhlelweni ezifana nama-caster asebenza kanzima abhekene nemithwalo esindayo kanye nemithelela. Ngaphezu kwalokho, i-TPR caster compound ishibhile kune-TPE, okwenza ibe nenzuzo kwezomnotho. Ngokufanayo ne-TPE, izinto ze-TPR caster zingaphinde zihlanganiswe ngamapulasitiki aqinile njenge-PA ne-PP, okwandisa ukuguquguquka kokusetshenziswa kwayo.
Fingqa
Izinto zokusika ze-TPU, TPE kanye ne-TPR ngayinye inezimpawu zayo ezihlukile kanye nezinhlelo zokusebenza. I-TPU yaziwa ngokumelana kwayo okuhle kakhulu nokuhuzuka, ukumelana nowoyela kanye nezakhiwo zokuthwala umthwalo; I-TPE ithandwa ngokuqina kwayo okuphezulu, amandla aphezulu kanye nokucutshungulwa kokubunjwa komjovo; I-TPR inendawo emkhakheni wama-caster asebenza kanzima ngenxa yokuqina kwayo okuhle kanye nezindleko eziphansi. Lapho sikhetha lezi zinto zokusika, sidinga ukwahlulela ngokwezimo ezithile zokusetshenziswa kanye nezidingo zokuqinisekisa ukuthi izinto ezikhethiwe zingahlangabezana nezidingo zethu.
