I-Thermoplastic Polyurethane (TPU) iyinto eguquguqukayo eyaziwa ngokuqina kwayo nokuqina.Kodwa-ke, kwezinye izinhlelo zokusebenza, kungase kube nesidingo sokunciphisa ubulukhuni bezinhlayiyana ze-TPU kuyilapho ngasikhathi sinye kuthuthukiswa ukumelana nemihuzuko.
Amasu okuzuza ukunciphisa ubulukhuni be-TPU kanye nokuthuthukisa ibhalansi yokumelana nemihuzuko.
1. Ukuhlanganisa Izinto Ezithambile
Enye yezindlela eziqondile zokunciphisa ubulukhuni be-TPU ngokuyihlanganisa nezinto ezithambile ze-thermoplastic.Izinketho ezijwayelekile zifaka i-TPE (Thermoplastic Elastomers) kanye namamaki athambile e-TPU.
Ukukhetha ngokucophelela impahla ethambile kanye nesilinganiso lapho ihlanganiswa khona ne-TPU kungasiza ekufinyeleleni izinga elifiswayo lokunciphisa ubulukhuni.
2. Indlela Entsha: Ukuhlanganisa Izinhlayiya ze-TPU ne-Novel Soft Material Si-TPV
Ukuhlanganisa izinhlamvana ze-85A TPU ne-SILIKE kwethulwe i-Soft Material Si-TPV(i-elastomer eguquguqukayo ye-vulcanizate thermoplastic Silicone-based), Le ndlela ishaya ibhalansi efiselekayo phakathi kokunciphisa ubulukhuni kanye nokwenyuka kokumelana nemihuzuko, ngaphandle kokuphazamisa ezinye izici zayo ezifiselekayo.
Indlela yokunciphisa ubulukhuni bezinhlayiya ze-TPU, Ifomula kanye Nokuhlola:
Ukwengezwa kwe-Si-TPV engu-20% ku-Harness of 85A TPU kunciphisa ubulukhuni bufike ku-79.2A
Qaphela:Idatha yokuhlola engenhla iyidatha yethu yokuhlola esebenzayo yaselebhu, futhi ayikwazi ukuqondwa njengokuzibophezela kwalo mkhiqizo, ikhasimende kufanele lihlolwe ngokusekelwe kokuqondile kwalo.
Kodwa-ke, Ukuhlola okunezilinganiso ezihlukene zokuhlanganisa kuvamile, kuhloswe ukuzuza inhlanganisela efanele yokuthamba nokumelana nemihuzuko.
3. Ihlanganisa Izigcwalisi Ezimelana Ne-Abrasion
Ukuze kuthuthukiswe ukumelana nemihuzuko, ochwepheshe baphakamisa ukuthi kufakwe izigcwalisi ezithile ezifana ne-carbon black, imicu yengilazi, i-silicone masterbatch, noma i-silicon dioxide.Lawa ma-Filler angakwazi ukuqinisa izakhiwo ze-TPU zokumelana nokugqokwa.
Kodwa-ke, kufanele kucatshangelwe ngokucophelela ubuningi nokuhlakazeka kwalezi zigcwalisi, njengoba inani eliningi lingase lithinte ukuguquguquka kwezinto.
4. Ama-Plasticizer nama-Ejenti Athambisayo
Njengendlela yokunciphisa ubulukhuni be-TPU, Abakhi be-TPU bangasebenzisa ama-plasticizer noma ama-ejenti athambisayo.Kubalulekile ukukhetha i-plasticizer efanelekile engakwazi ukwehlisa ubulukhuni ngaphandle kokuphazamisa ukumelana nokuhuzuka.Amapulasitiki ajwayelekile asetshenziswa ne-TPU afaka i-dioctyl phthalate (DOP) ne-dioctyl adipate (DOA).Kufanele kuqikelelwe ukuthi i-plasticizer ekhethiwe iyahambisana ne-TPU futhi ayithinti kabi ezinye izinto ezinjengamandla aqinile noma ukumelana namakhemikhali.Ngaphezu kwalokho, Umthamo wama-plasticizers kufanele ulawulwe ngokucophelela ukuze ulondoloze ibhalansi oyifunayo.
5. I-Fine-Tuning Extrusion and Processing Parameters
Ukulungisa amapharamitha we-extrusion kanye nokucubungula kubalulekile ekuzuzeni inhlanganisela efiselekayo yokuqina okuncishisiwe kanye nokungezwani okuthuthukisiwe komhuzuko.Lokhu kuhlanganisa ukulungisa amapharamitha afana nezinga lokushisa, ingcindezi, namazinga okupholisa ngesikhathi sokukhipha.
Amazinga okushisa aphansi e-extrusion kanye nokupholisa ngokucophelela kungaholela ku-TPU ethambile ngenkathi kulungiselelwa ukusakazeka kwezihlungi ezimelana nokuhuzuka.
6. Amasu Okwenza Ngemva Kokucubungula
Amasu okucubungula ngemva kokucutshungulwa okufana nokudonsa, ukwelula, noma ngisho nokwelashwa kwangaphandle kungathuthukisa ukumelana nemihuzuko ngaphandle kokubeka engcupheni ubulukhuni.
I-Annealing, ikakhulukazi, ingathuthukisa ukwakheka kwe-crystalline ye-TPU, ikwenze imelane nokuguga.
Sengiphetha, ukuzuza ibhalansi ethambile yobulukhuni be-TPU encishisiwe kanye nokumelana nokuhuzuka okuthuthukisiwe kuyinqubo enezici eziningi.Abakhiqizi be-TPU bangasebenzisa ukukhethwa kwezinto ezibonakalayo, ukuhlanganisa, izigcwalisi ezingaba yi-abrasion, amapulasitiki, ama-Softening Agents, kanye nokulawula okunembile kwamapharamitha we-extrusion ukuze kulungiswe kahle izakhiwo zezinto ezibonakalayo ukuze zihambisane nezidingo ezihlukile zohlelo olunikeziwe.
Yilokhu okudingayo Ifomula Ephumelelayo eyehlisa Ubulukhuni Bezinhlayiyana ze-TPU futhi Ithuthukise Ukumelana Nokuhushulwa!
Xhumana no-SILIKE, i-Si-TPV yethu ikusiza ukuthi uthole ukuthamba okufanele, ukuguquguquka, ukuqina, umphumela we-matt ongaphezulu, nezinye izici ezibalulekile zemikhiqizo yakho esekelwe kuyizinhlayiyana ze-TPU!
