Amathoyizi we-Thermoplastic elastomer TPE/TPR, ngokusekelwe ku-SEBS kanye ne-SBS, ziwuhlobo lwezinto ze-polymer alloy ezinezakhiwo ezijwayelekile zokucubungula ipulasitiki kodwa izakhiwo zenjoloba.Baye bashintsha kancane kancane amapulasitiki endabuko futhi yizinto ezikhethwayo zemikhiqizo yaseShayina ukuya phesheya futhi ithumele eYurophu, eMelika, e-Australia, eJapane nakwezinye izindawo.Inokuqina okuhle kwe-tactile, ukulungiswa okuguquguqukayo kombala nobulukhuni, ukuvikelwa kwemvelo, i-halogen-free, engenabuthi futhi ayinambitheki;Ukumelana nokushelela nokugqokwa, ukumelana nokukhathala okunamandla, ukumuncwa okuhle kakhulu kokushaqeka, ukumelana okuhle kwe-UV, ukumelana ne-ozone nokumelana namakhemikhali;Ngesikhathi sokucutshungulwa, akudingi ukomiswa futhi kungenziwa kabusha.Ingenziwa ngokubunjwa komjovo wesibili, ihlanganiswe futhi iboshwe nge-PP, PE, PS,I-ABS, i-PC, i-PA nezinye izinto ze-matrix, noma zakhiwe ngokwehlukana.Faka esikhundleni se-PVC ethambile kanye nerabha ye-silicone.
Iphunga elikhishwa amathoyizi e-TPR kungenxa yezizathu eziningi, okuhlanganisa umshini, izinyathelo zokusebenza, nezindlela zokusebenza.Akunakugwema ukuthi i-TPR izoba nephunga, kodwa singanciphisa iphunga ukuze abantu bangazizwa kabi, ukuze wonke umuntu avume.Abakhiqizi abahlukene banamafomula abo, futhi iphunga elikhiqizwayo lihlukile.Ukuze kuzuzwe iphunga elikhanyayo, kudinga inhlanganisela ephelele yefomula nenqubo ukuze kube nokusebenza okuhle.
1. Ifomula
Iningi lamathoyizi enziwe ngezinto ze-TPR ezine-SBS njenge-substrate eyinhloko.I-SBS kufanele icatshangelwe ekukhethweni.I-SBS ngokwayo inephunga futhi iphunga leglue lamafutha likhulu kunalelo leglue elomile.Zama ukusebenzisa i-K glue ukuze uthuthukise ubulukhuni, unciphise inani le-PS, futhi ukhethe uwoyela nge-flash point ephezulu ye-wax kapharafini.Amafutha amhlophe angcolile azoba nephunga elithile ngemva kokushisa, ngakho-ke kunconywa ukukhetha imikhiqizo evela kubakhiqizi abavamile.
2. Inqubo
Imikhiqizo yemifanekiso ye-TPR ene-SBS njengengxenye engaphansi eyinhloko kufanele ilawule inqubo ngokuqinile.Kungcono ukungasebenzisi izigubhu zokuxuba ngesivinini esikhulu kanye nezivundlile zokuxuba izinto, futhi isikhathi akufanele sibe side kakhulu.Ngokuvamile, izinga lokushisa lokucubungula kufanele lilawulwe liphansi ngangokunokwenzeka.180 ℃ esigabeni sokugunda kanye no-160 ℃ ezigabeni zakamuva kwanele.Ngokuvamile, i-SBS engaphezu kuka-200 ℃ ijwayele ukuguga, futhi iphunga liyoba libi kakhulu.Izinhlayiya ze-TPR ezilungiselelwe kufanele zipholiswe ngokushesha ngangokunokwenzeka ukuze zivuse iphunga, futhi ziqinisekise ukuthi akukho ukushisa okukhulu ngesikhathi sokupakisha.
3. Ukucubungula okulandelayo
Ngemuva kokuthi amathoyizi epholiswe ukubumba komjovo we-TPR, ungawapakishi ngokushesha.Singavumela imikhiqizo ukuthi iguquke emoyeni cishe izinsuku ezi-2.Ngaphezu kwalokho, i-essence nayo ingangezwa ngesikhathi sokubumba umjovo ukumboza ukunambitheka kwe-TPR ngokwayo.
