I-Thermoplastic Polyurethane (TPU) yimathiriyeli eguquguqukayo eyaziwa ngokuhlala kwayo kunye nokomelela kwayo. Nangona kunjalo, kwizicelo ezithile, kunokubakho isidingo sokunciphisa ubulukhuni be-TPU granules ngelixa ngaxeshanye uphucula ukuxhathisa kwe-abrasion.
Amaqhinga okuphumeza ukunciphisa ubulukhuni be-TPU kunye nokuphucula ibhalansi yokumelana ne-abrasion.
1. Ukudibanisa ngezinto ezithambileyo
Enye yeendlela ezithe ngqo zokunciphisa ubulukhuni be-TPU kukuyidibanisa kunye nemathiriyeli ethambileyo ye-thermoplastic. Iinketho eziqhelekileyo ziquka i-TPE (i-Thermoplastic Elastomers) kunye namabakala athambileyo e-TPU.
Ukukhethwa ngokucokisekileyo kwezinto ezithambileyo kunye nomlinganiselo apho idityaniswe khona ne-TPU inokunceda ukufezekisa inqanaba elifunekayo lokunciphisa ubulukhuni.
2.Indlela eNtsha: Ukudibanisa amasuntswana eTPU ngeNovel Soft Material yeSi-TPV
Ukudibanisa i-85A TPU granules kunye ne-SILIKE isungulwe i-Soft Material Si-TPV (i-dynamic vulcanizate thermoplastic Silicone-based elastomer), Le ndlela ibetha ibhalansi efunekayo phakathi kokunciphisa ubulukhuni kunye nokwanda kokuxhathisa kwe-abrasion, ngaphandle kokuphazamisa ezinye iimpawu ezinqwenelekayo.
Indlela yokunciphisa ubulukhuni bamasuntswana e-TPU, Ifomula kunye noVavanyo:
Ukongezwa kwe-20% ye-Si-TPV kuBulukhuni be-85A TPU kunciphisa ubunzima kwi-79.2A
Phawula:Le datha yovavanyo engentla yidatha yethu yovavanyo olusebenzayo elebhu, kwaye ayinakuqondwa njengokuzibophelela kwale mveliso, umthengi kufuneka avavanywe ngokusekwe kweyakhe.
Nangona kunjalo, uVavanyo olunereyishini ezahlukeneyo zokuxuba luqhelekile, lujolise ekufikeleleni indibaniselwano eyona ilungileyo yokuthamba kunye nokuxhathisa kwe-abrasion.
3. Ukubandakanya i-Abrasion-Resistant Fillers
Ukomeleza ukuxhathisa kwe-abrasion, iingcali zicebisa ukuba kufakwe izihluzi ezithile ezifana nekhabhoni emnyama, iifiber zeglasi, i-silicone masterbatch, okanye isilicon dioxide. Ezi Fili zinokomeleza iipropathi zokumelana nokunxiba kwe-TPU.
Nangona kunjalo, kufuneka kuthathelwe ingqalelo ngononophelo kubuninzi kunye nokusasazwa kwezi zihluzi, njengoko isixa esigqithisileyo sinokuchaphazela ukuguquguquka kwezinto.
4. IiPlastiki kunye nee-Agents zokuthambisa
Njengendlela yokunciphisa ubulukhuni be-TPU, abavelisi be-TPU banokusebenzisa iiplastiki okanye izinto zokuthambisa. Kubalulekile ukukhetha i-plasticizer efanelekileyo enokuthi ihlise ubulukhuni ngaphandle kokuphazamisa ukuxhathisa i-abrasion. Iiplastiki eziqhelekileyo ezisetyenziswa kunye ne-TPU ziquka i-dioctyl phthalate (DOP) kunye ne-dioctyl adipate (DOA). Ukunyamekela kufuneka kuthathwe ukuze kuqinisekiswe ukuba i-plasticizer ekhethiweyo iyahambelana ne-TPU kwaye ayichaphazeli kakubi ezinye iipropathi ezinjengokuqina kokuqina okanye ukuxhathisa imichiza. Ukongeza, idosi yeeplasticizers kufuneka ilawulwe ngononophelo ukugcina ibhalansi efunekayo.
5. I-Fine-Tuning Extrusion kunye ne-Processing Parameters
Ukulungelelanisa i-extrusion kunye neparameters zokusetyenzwa kubaluleke kakhulu ekuphumezeni indibaniselwano enqwenelekayo yobunzima obuncitshisiweyo kunye nokuqina kokuxhathisa kwe-abrasion. Oku kubandakanya uhlengahlengiso lweeparamitha ezifana nobushushu, uxinzelelo, kunye namazinga okupholisa ngexesha le-extrusion.
Amaqondo obushushu asezantsi e-extrusion kunye nokupholisa ngononophelo kunokukhokelela kwi-TPU ethambileyo ngelixa ulungiselela ukusasazwa kwezihluzi ezinganyangekiyo kwi-abrasion.
6. IiTeknikhi zokuSebenza emva koKusebenza
Iindlela zokusetyenzwa emva kokwenziwa kwe-annealing, ukolula, okanye unyango olungaphezulu kunokomeleza ngakumbi ukunganyangeki kwe-abrasion ngaphandle kokubeka esichengeni ubulukhuni.
I-Anealing, ngokukodwa, inokuphucula i-crystalline structure ye-TPU, iyenze ukuba ixhathise ngakumbi ukunxiba kunye nokukrazula.
Ukuqukumbela, ukufikelela kwibhalansi ethambileyo yokuncipha kobunzima be-TPU kunye nokuphuculwa kokuxhathisa kwe-abrasion yinkqubo eneenkalo ezininzi. Abavelisi be-TPU banokunyusela ukhetho lwezinto eziphathekayo, ukudibanisa, izigcwalisi ezinganyangekiyo kwi-abrasion, iiplastiki, ii-Agents zokuthambisa, kunye nolawulo oluchanekileyo lweeparamitha ze-extrusion ukulungelelanisa iipropati eziphathekayo ukuze zihambelane neemfuno ezizodwa zesicelo esinikiweyo.
Yile nto oyifunayo Ifomula yokuPhumelela enciphisa Ubulukhuni be-TPU ye-Particle Hardness kunye nokuphucula ukuxhathisa i-Abrasion!
Qhagamshelana ne-SILIKE, i-Si-TPV yethu ikunceda ukuba ufikelele ekuthambeni okufanelekileyo, ukuguquguquka, ukuqina, isiphumo se-matt yomhlaba, kunye nezinye iipropathi ezibalulekileyo kwiimveliso zakho ezisekwe ngamasuntswana e-TPU!
