I-Thermoplastic Polyurethane (TPU) yinto eguquguqukayo eyaziwa ngokuqina kwayo nokuqina kwayo. Nangona kunjalo, kwezinye iindlela zokusebenza, kunokubakho imfuneko yokunciphisa ubulukhuni beegranule zeTPU ngelixa ngaxeshanye kuphucula ukumelana nokukrweleka.
Amaqhinga okufezekisa ukunciphisa ubulukhuni be-TPU kunye nokuphucula ibhalansi yokumelana nokukrweleka.
1. Ukuxuba ngezinto ezithambileyo
Enye yezona ndlela zilula zokunciphisa ubulukhuni beTPU kukuyixuba nezinto ezithambileyo zethermoplastic. Iindlela eziqhelekileyo ziquka iTPE (Thermoplastic Elastomers) kunye neeklasi ezithambileyo zeTPU.
Ukukhetha ngononophelo izinto ezithambileyo kunye nomlinganiselo apho zixutywe khona ne-TPU kunokunceda ekufezekiseni inqanaba elifunekayo lokunciphisa ubulukhuni.
2. Indlela Entsha: Ukudibanisa iiTPU Particles kunye neNovel Soft Material Si-TPV
Ukudibanisa iigranules ze-85A TPU kunye ne-SILIKE launch soft Material Si-TPV (dynamic vulcanizate thermoplastic Silicone-based elastomer), Le ndlela ifikelela kwibhalansi efunekayo phakathi kokunciphisa ubulukhuni kunye nokumelana nokukrala okwandisiweyo, ngaphandle kokuphazamisa ezinye iimpawu zayo ezinqwenelekayo.
Indlela yokunciphisa ubulukhuni bee-TPU particles, iFormula kunye noVavanyo:
Ukongezwa kwe-20% ye-Si-TPV kwi-Hardness ye-85A TPU kunciphisa ubulukhuni ukuya kwi-79.2A
Phawula:Idatha yovavanyo engentla yidatha yethu yovavanyo olusebenzayo lwelabhoratri, kwaye ayinakuqondwa njengokuzinikela kwale mveliso, umthengi kufuneka avavanywe ngokusekelwe kwinkcukacha zakhe.
Nangona kunjalo, uvavanyo ngemilinganiselo eyahlukeneyo yokuxuba luqhelekile, lujolise ekufezekiseni indibaniselwano efanelekileyo yokuthamba kunye nokumelana nokukrweleka.
3. Ukubandakanya izizalisi ezimelana nokurhawuzelelwa
Ukuphucula ukumelana nokukrala, iingcali zicebisa ukuba kufakwe izizalisi ezithile ezifana ne-carbon black, iifayibha zeglasi, i-silicone masterbatch, okanye i-silicon dioxide. Ezi Zizalisi zinokuqinisa iipropati ze-TPU zokumelana nokukrala.
Nangona kunjalo, kufuneka kuqwalaselwe ngononophelo ubungakanani kunye nokusasazeka kwezi zihluzo, njengoko ubungakanani obugqithisileyo bunokuchaphazela ukuguquguquka kwezinto.
4. Izinto zokucoca iiplastiki kunye neearhente zokuthambisa
Njengendlela yokunciphisa ubulukhuni be-TPU, Abavelisi be-TPU banokusebenzisa ii-plasticizers okanye ii-arhente zokuthambisa. Kubalulekile ukukhetha i-plasticizer efanelekileyo enokunciphisa ubulukhuni ngaphandle kokuphazamisa ukumelana nokukrweleka. Ii-plasticizers eziqhelekileyo ezisetyenziswa ne-TPU ziquka i-dioctyl phthalate (DOP) kunye ne-dioctyl adipate (DOA). Kufuneka kuthathwe unonophelo ukuqinisekisa ukuba i-plasticizer ekhethiweyo iyahambelana ne-TPU kwaye ayichaphazeli kakubi ezinye iimpawu ezifana namandla okuxinana okanye ukumelana neekhemikhali. Ukongeza, umthamo wee-plasticizers kufuneka ulawulwe ngononophelo ukugcina ibhalansi efunekayo.
5. Iiparameter zoLungiso oluLungileyo kunye nokuCwangcisa
Ukulungisa iiparameters zokukhupha nokucubungula kubalulekile ekufezekiseni indibaniselwano enqwenelekayo yokunciphisa ubulukhuni kunye nokumelana nokukrala okuphuculweyo. Oku kuquka ukutshintsha iiparameters ezifana nobushushu, uxinzelelo, kunye namazinga okupholisa ngexesha lokukhupha.
Amaqondo obushushu aphantsi okukhupha izinto kunye nokupholisa ngononophelo kunokukhokelela kwi-TPU ethambileyo ngelixa kulungiswa ukusasazeka kwezizalisi ezimelana nokurhawuzelelwa.
6. Iindlela Zokusebenza Emva Kokucubungula
Iindlela zokulungisa emva kokufakelwa ezifana nokuqhoboshela, ukolula, okanye unyango lomphezulu zinokuphucula ngakumbi ukumelana nokukrweleka ngaphandle kokubeka emngciphekweni ubulukhuni.
I-Annealing, ngakumbi, inokuphucula ulwakhiwo lwe-TPU oluyikristale, nto leyo eyenza ukuba ikwazi ukumelana nokuguguleka.
Ukuqukumbela, ukufikelela kwibhalansi ethambileyo yobunzima be-TPU obuncitshisiweyo kunye nokumelana nokukrala okuphuculweyo yinkqubo enamacala amaninzi. Abavelisi be-TPU banokusebenzisa ukukhethwa kwezinto, ukuxuba, izizalisi ezimelana nokukrala, iiplastiki, ii-Agent zokuthambisa, kunye nolawulo oluchanekileyo lweeparamitha zokukhupha ukuze kulungiswe iipropati zezinto ukuze zihambelane neemfuno ezizodwa zesicelo esithile.
Yile nto uyidingayo. Ifomula ephumelelayo enciphisa ubulukhuni beTPU Particle kwaye iphucule ukuxhathisa ukurhawuzelelwa!
Qhagamshelana ne-SILIKE, i-Si-TPV yethu ikunceda ufumane ukuthamba okufanelekileyo, ukuguquguquka, ukuqina, isiphumo se-surface matt, kunye nezinye iimpawu ezibalulekileyo kwiimveliso zakho ezisekwe kwi-TPU!
