I-Thermoplastic Polyurethane (TPU) iyinto eguquguqukayo eyaziwa ngokuqina kwayo nokuqina kwayo. Kodwa-ke, kwezinye izinhlelo zokusebenza, kungase kube nesidingo sokunciphisa ubulukhuni be-TPU granules ngenkathi kuthuthukiswa ukumelana nokuklwebheka ngasikhathi sinye.
Amasu okufeza ukunciphisa ubulukhuni be-TPU nokuthuthukisa ibhalansi yokumelana nokuklwebheka.
1. Ukuxubana Nezinto Ezithambile
Enye yezindlela ezilula kakhulu zokunciphisa ubulukhuni be-TPU ukuyixuba nezinto ezithambile ze-thermoplastic. Izinketho ezivamile zifaka phakathi i-TPE (Thermoplastic Elastomers) kanye namazinga athambile e-TPU.
Ukukhetha ngokucophelela izinto ezithambile kanye nesilinganiso lapho zihlanganiswa khona ne-TPU kungasiza ekufinyeleleni izinga elifunekayo lokunciphisa ubulukhuni
2. Indlela Entsha: Ukuhlanganisa Izinhlayiya ze-TPU Nezinto Ezintsha Ezithambile ze-Si-TPV
Ukuhlanganisa ama-granule e-85A TPU ne-SILIKE launch soft Material Si-TPV (dynamic vulcanizate thermoplastic Silicone-based elastomer), Le ndlela ifinyelela ibhalansi efiselekayo phakathi kokunciphisa ubulukhuni kanye nokumelana nokuklwebheka okwandisiwe, ngaphandle kokubeka engcupheni ezinye izakhiwo zayo ezifiselekayo.
Indlela yokunciphisa ubulukhuni bezinhlayiya ze-TPU, iFomula kanye nokuhlola:
Ukwengezwa kwe-20% Si-TPV ku-Ubulukhuni be-85A TPU kunciphisa ubulukhuni bube yi-79.2A
Qaphela:Idatha yokuhlola engenhla iyidatha yethu yokuhlola esebenzayo yelabhorethri, futhi ayikwazi ukuqondwa njengokuzibophezela kwalo mkhiqizo, ikhasimende kufanele lihlolwe ngokusekelwe kulokho elikuqondile.
Kodwa-ke, ukuhlola ngezilinganiso ezahlukene zokuxuba kuyinto evamile, kuhloswe ukufeza inhlanganisela efanele yokuthamba nokumelana nokuhuzuka.
3. Ukufaka Ama-Filler Amelana Nokuguguleka
Ukuze kuthuthukiswe ukumelana nokuguguleka, ochwepheshe basikisela ukufaka izithasiselo ezithile ezifana ne-carbon black, imicu yengilazi, i-silicone masterbatch, noma i-silicon dioxide. Lawa ma-Filler angaqinisa izakhiwo ze-TPU zokumelana nokuguguleka.
Kodwa-ke, kufanele kucatshangelwe ngokucophelela inani kanye nokusabalala kwalezi zigcwalisi, njengoba inani eliningi kakhulu lingathinta ukuguquguquka kwezinto.
4. Izinto Zokwenza Ipulasitiki kanye Nezinto Zokuthambisa
Njengendlela yokunciphisa ubulukhuni be-TPU, Abakhiqizi be-TPU bangasebenzisa ama-plasticizer noma ama-ejenti okuthambisa. Kubalulekile ukukhetha i-plasticizer efanelekile enganciphisa ubulukhuni ngaphandle kokuphazamisa ukumelana nokuklwebheka. Ama-plasticizer avamile asetshenziswa ne-TPU afaka i-dioctyl phthalate (DOP) kanye ne-dioctyl adipate (DOA). Kumelwe kuqashelwe ukuqinisekisa ukuthi i-plasticizer ekhethiwe iyahambisana ne-TPU futhi ayithinti kabi ezinye izakhiwo ezifana namandla okubamba noma ukumelana namakhemikhali. Ngaphezu kwalokho, umthamo wama-plasticizer kufanele ulawulwe ngokucophelela ukuze kulondolozwe ibhalansi oyifunayo.
5. Amapharamitha Okulungisa Nokucubungula Okuhle
Ukulungisa amapharamitha okukhipha kanye nokucubungula kubalulekile ekufinyeleleni inhlanganisela efiselekayo yokunciphisa ubulukhuni kanye nokumelana okuthuthukisiwe kokuhuzuka. Lokhu kuhilela ukuguqula amapharamitha afana nokushisa, ingcindezi, kanye namazinga okupholisa ngesikhathi sokukhipha.
Amazinga okushisa aphansi okukhipha kanye nokupholisa ngokucophelela kungaholela ku-TPU ethambile ngenkathi kuthuthukiswa ukusabalala kwama-filler amelana nokuguguleka.
6. Amasu Okucubungula Ngemva Kokucubungula
Amasu okucubungula ngemuva kokucubungula njengokufaka i-anneal, ukwelula, noma ngisho nokwelashwa kwendawo kungathuthukisa kakhulu ukumelana nokuklwebheka ngaphandle kokubeka engcupheni ubulukhuni.
Ikakhulukazi i-Annealing ingathuthukisa isakhiwo se-TPU esicwebezelayo, okwenza imelane kakhulu nokuguguleka.
Ekuphetheni, ukufeza ibhalansi ebucayi yokuncipha kobulukhuni be-TPU kanye nokumelana nokuklwebheka okuthuthukisiwe kuyinqubo enezici eziningi. Abakhiqizi be-TPU bangasebenzisa ukukhethwa kwezinto, ukuxuba, izigcwalisi ezingamelana nokuklwebheka, ama-plasticizer, ama-Softening Agents, kanye nokulawula okunembile kwamapharamitha okukhipha ukuze kulungiswe izakhiwo zezinto ukuze zivumelane nezidingo ezihlukile zohlelo lokusebenza oluthile.
Yilokhu okudingayo Ifomula Ephumelelayo enciphisa Ukuqina Kwezinhlayiya ze-TPU futhi Ithuthukise Ukumelana Nokuguguleka!
Xhumana ne-SILIKE, i-Si-TPV yethu ikusiza ukuthi uthole ukuthamba okuhle, ukuguquguquka, ukuqina, umphumela we-surface matt, kanye nezinye izakhiwo ezibalulekile zemikhiqizo yakho esekelwe ku-TPU!
