I-Thermoplastic Polyurethane (TPU) iyinto eguquguqukayo eyaziwa ngokuqina kwayo nokuqina. Kodwa-ke, kuzinhlelo ezithile, kungahle kube nesidingo sokunciphisa ubulukhuni be-TPU granules ngenkathi ngasikhathi sithuthukise ukumelana ne-abrasion.
Amasu okufinyelela ukunciphisa ubulukhuni be-TPU futhi uthuthukise ukumelana nokumelana ne-abrasion.
1. Ukuhlangana ngezinto ezithambile
Enye yezindlela eziqonde ngqo kakhulu zokunciphisa ubulukhuni be-TPU ngokuyihlanganisa ngezinto ezithambile ze-thermoplastic. Izinketho ezijwayelekile zifaka i-TPE (i-thermoplastic lastomers) namamaki athambile e-TPU.
Ukukhetha ngokucophelela kwezinto ezithambile kanye nesilinganiso lapho kuhlanganiswa khona ne-TPU kungasiza ukufeza izinga olifunayo lokuncishiswa kobunzima
Indlela entsha: Ukuxuba izinhlayiya ze-TPU nge-Novel Soft Material Si-TPV
Ukuhlanganisa ama-85a TPU Granules nge-Silike yethule impahla ethambile ye-SI-TPV (Dynamic Vulcate Thermoplastic allstomer), le ndlela ishaya ibhalansi efiselekayo phakathi kokuncishiswa kobulukhuni kanye nokuphikisana nezinye izakhiwo zayo ezifiselekayo.
Indlela yokunciphisa ubulukhuni bezinhlayiya ze-TPU, ifomula kanye nokuhlola:
Ukungezwa kwe-20% TPV kubulukhuni be-85a TPU kunciphisa ubulukhuni ku-79.2a
Qaphela:Idatha yokuhlola engenhla iyidatha yethu yokuhlola okusebenzayo, futhi ayikwazi ukuqondakala njengokuzibophezela kwalo mkhiqizo, ikhasimende kufanele lihlolwe ngokususelwa kokuthile kwalo.
Kodwa-ke, ukuhlolwa ngezilinganiso ezihlukile ezihlanganisiwe kuvamile, kuhloswe ukufeza inhlanganisela efanelekile yokuthambisa kanye nokumelana ne-abrasion.
3. Ukufaka ama-fillers angenakumelana ne-abrasion
Ukuze uthuthukise ukumelana ne-abrasion, ochwepheshe baphakamisa ukuthi kufakwe ama-fillers athile afana nekhabhoni emnyama, imicu yengilazi, i-silicone masterbatch, noma i-silicon dioxide. Lawa ma-filler angaqinisa izakhiwo zokumelana ne-TPU.
Kodwa-ke, ukucatshangelwa ngokucophelela kufanele kunikezwe inani kanye nokusakazwa kwalaba bakhilimu, njengoba inani elikhulu ngokweqile lingathinta ukuguquguquka kwezinto ezibonakalayo.
4. Amapulangwe kanye nama-ejenti athambisayo
Njengendlela yokwehlisa ubulukhuni be-TPU, abakhiqizi be-TPU bangasebenzisa amapulasitiki noma ama-ejenti athambisayo. Kubalulekile ukukhetha ipulasitiki efanelekile engangehlisa ubunzima ngaphandle kokuyekethisa ukumelana nokukhalaza. Amapulasitiki ajwayelekile asetshenziswa nge-TPU kufaka phakathi i-dioctyl perthalate (dop) ne-dioctyl adipate (doa). Ukunakekelwa kumele kuthathwe ukuqinisekisa ukuthi ipulasitiki ekhethiwe iyahambelana ne-TPU futhi ayiba nomthelela omubi kwezinye izakhiwo ezinjengamandla ashubile noma ukumelana kwamakhemikhali. Ngaphezu kwalokho, umthamo wamapulasitiki kufanele ulawulwe ngokucophelela ukuze ulondoloze ibhalansi oyifunayo.
I-5 ukukhishwa okuhle kokukhishwa kwamapharamitha wokucubungula
Ukulungisa ukukhishwa kanye namapharamitha wokucubungula kuyinto ebalulekile ekufezeni inhlanganisela oyifunayo yobulukhuni obuncishisiwe futhi bathuthukise ukumelana ne-abrasion. Lokhu kufaka phakathi ukuguqula amapharamitha afana nokushisa, ingcindezi, kanye namazinga okupholisa ngesikhathi sokukhishwa.
Amazinga okushisa aphansi aphansi kanye nokupholisa ngokucophelela kungaholela ku-tpu ethambile ngenkathi ulungiselela ukuhlakazeka kwama-fillers alwa ne-abrasion.
6. Amasu wokusebenza
Amasu wokusebenza angemuva afana nokungenisa, ukwelula, noma ukwelashwa komhlaba kungaqhubekisela phambili ukumelana ne-abrasion ngaphandle kokuyekethisa ubulukhuni.
Ukuncika, ikakhulukazi, kungathuthukisa ukwakheka kwe-crystalline ye-TPU, okwenza kube ukumelana nokuklebhula ngokwengeziwe.
Ekuphetheni, ukuzuza ibhalansi ebucayi yobulukhuni be-TPU obuncishisiwe futhi kwathuthukisa ukumelana ne-abrasion inqubo ehlukahlukene. Abakhiqizi be-TPU bangavuselela Ukukhethwa kwezinto ezibonakalayo, okuhlanganisiwe, ama-fillers amelana ne-abrasion, ama-ejenti athambisa, kanye nokulawulwa okunembile kwamapharamitha okukhishwa ukuze akwazi ukwenza kahle izidingo ezihlukile zohlelo lokusebenza olunikeziwe.
Lokhu yilokho okudingayo ifomula ewinayo eyehlisa ubulukhuni be-TPU futhi ithuthukise ukumelana ne-abrasion!
Thintana Silike, I-SI-TPV yethu ikusiza ukuthi uthole ukuthamba okuhle, ukuguquguquka, ukuqina, umphumela we-matt ongaphezulu, nezinye izakhiwo ezibalulekile zemikhiqizo yakho esekelwe kwi-TPU!
