Umehluko phakathi kwama-caster e-PP nama-caster e-TPR

Empilweni yethu yansuku zonke, ama-caster ayisengezo esivamile, asetshenziswa kabanzi efenisha ehlukahlukene, amathuluzi kanye nemishini. Phakathi kwawo, ama-caster e-PP kanye nama-caster e-TPR ayizinhlobo ezimbili ezivamile. Lesi sihloko sizokwethula umehluko phakathi kwama-caster e-PP kanye nama-caster e-TPR ngokuningiliziwe.

I. Umehluko Wezinto Ezibonakalayo
Ama-PP casters enziwe kakhulu ngezinto ze-polypropylene, kuyilapho ama-TPR casters enziwe ngezinto zerabha ze-thermoplastic. Uhlobo nezici zalezi zinto ezimbili zihlukile kakhulu.

I-Polypropylene (PP): I-Polypropylene iyi-thermoplastic e-semi-crystalline, enokumelana okukhulu nokumelana namakhemikhali, futhi kulula ukuyicubungula. Ama-PP casters ngokuvamile anobulukhuni namandla aphezulu, afaneleka ngezikhathi ezidinga umthamo omkhulu womthwalo.
Irabha ye-thermoplastic (TPR): Irabha ye-thermoplastic uhlobo lwe-thermoplastic olunokuguquguquka kwerabha, ukuguquguquka okuhle kanye nokumelana nokuguguleka, ama-caster e-TPR ngokuvamile anokuthungwa okuthambile, afaneleka ngezikhathi ezidinga ukuthokomelezwa nokuthula.

Okwesibili, izici zokusebenza
Ukumelana Nokuguguleka: Ukumelana nokuguguleka kwama-TPR casters kuphakeme kunokwe-PP casters ngoba kunendawo ethambile evumelana kangcono nomhlabathi.
Ukumelana nokushayisana: Nakuba ama-PP casters enokumelana okungcono nokushayisana, kwezinye izimo, ama-TPR casters angase abe nokumelana okungcono nokushayisana.
Ukucutshungulwa: Ama-PP casters kulula ukuwacubungula futhi angabunjwa ngomjovo emazingeni okushisa aphezulu. Ama-TPR casters awacutshungulwa kakhulu futhi ngokuvamile adinga ukusetshenziswa kokubumba komjovo wesibili.
Intengo: Ngokuvamile, ama-TPR casters abiza kakhulu kunama-PP casters ngenxa yenqubo yokukhiqiza eyinkimbinkimbi kakhulu.

Isicelo
Ama-PP casters: afaneleka ngezikhathi ezidinga amandla aphezulu okuthwala imithwalo kanye nokumelana nokuguguleka okuphezulu, njengemishini esindayo, amashalofu, njll.
Ama-TPR casters: afanele isidingo sokuguquguquka okuhle, ukumelana okuhle nokushayisana, ukumelana nokuguguleka, njengemishini yezokwelapha, imishini yelabhorethri.
