1. Ubulukhuni
Ukuqina kusho ikhono lento yokumelana nento eqinile ecindezelayo endaweni yayo. Ngoba ukuthamba noma ubulukhuni bento ngokuvamile kuyinto yokuqala okufanele uyicabangele lapho ukhetha into, futhi ubulukhuni buhlobene nezinye izici ezibalulekile zokuklama, njenge-tensile modulus kanye ne-flexural modulus. Ngakho-ke, inhloso yokuhlolwa kobulukhuni ukuqinisekisa ukuthi imininingwane yobulukhuni be-thermoplastic elastomers iyiqiniso.
Ithuluzi elisetshenziswa kakhulu ekulinganiseni ubulukhuni berabha yi-Shore hardness tester. I-TPE Ukuhlolwa kwezinto ngokuvamile kusebenzisa abahloli bokuqina ababili kuphela: i-ShoreA kanye ne-ShoreD.
2. Isethi yokucindezela
Isethi yokucindezela ibhekisela ekuhlolweni kokuguquguquka okungapheli kwezinto zerabha noma ze-elastomer ngaphansi kokucindezela (ukufaka umthwalo enanini elithile lokuziphatha, ake sithi 25%) kanye nasezingeni lokushisa elihlukile. Zonke izinto ze-polymer zidlula ekuziphatheni kokuqhekeka ngaphansi kwezimo ezithile zomthwalo, kanti ukuhlolwa kwesethi yokucindezela kuyisilinganiso esilinganiselwe sokuziphatha kokuqhekeka kwezinto ngaphansi komthwalo wokucindezela.
Amathuluzi adingekayo okuhlola isethi yokucindezela ikakhulukazi ihhavini kanye nedivayisi yokucindezela, ehlanganisa ipuleti lokucindezela, i-limiter kanye ne-fastener.
Ngokuvamile ukucindezelwa kwe-Shore10-80A kungu-25%, ukucindezelwa kwe-Shore80-89A kungu-15%, kanti ukucindezelwa kwe-Shore90-95A kungu-10%.
3. Ukuguquguquka okuhlala njalo kwe-tensile
Ukuguquguquka okuhlala njalo kokudonsa kubhekisela ekuguqukeni okusele kwesampula ngemva kokuba inwetshiwe ngaphansi kwamandla athile okudonsa, futhi kuvezwa njengephesenti lobude bokuqala. Zonke izinto ze-elastomer zidlula ekuphumuleni kokusetshenziswa okuhambisanayo ngaphansi kokucindezeleka okuthile, futhi ukuhlolwa kwesethi yokudonsa kuyisilinganiso esilinganiselwe sokuziphatha kokuphumula kokucindezeleka kwento engaphansi kokucindezeleka kokudonsa.
4. Amandla eqine
Amandla okudonsa abhekisela ekucindezelekeni okuphezulu kakhulu okwenzeka ngesikhathi sokwelulwa kwesampula kuze kube yilapho iphuka, futhi kuyisilinganiso esinembile sokumelana kokudonsa kwezinto ze-elastomer.
5. Amandla okudabula
Inqubo yokuklebhula ngomshini ezokhiqizwa futhi yandiswe ngephuzu elithile lezinto zerabha nepulasitiki ngaphansi kwesenzo sokugxila okuphezulu kokucindezeleka izoholela ekuqhekekeni, ekuqhekekeni noma ekuguqukeni kwendawo kwezinto, futhi amandla okuklebhula ayisibonakaliso sobuningi bamandla amakhulu okubhubhisa adingekayo kule nqubo yokuklebhuka.
6. Ukumelana namafutha
Ukuhlolwa kokumelana nowoyela ngokuyinhloko kuhloswe ukukala ushintsho lwento ethile ezinkombeni eziningi zokusebenza (umthamo, ubulukhuni, amandla okudonsa, njll.) kumafutha ajwayelekile ahlukene okubhekisela, ikakhulukazi ukuqondisa into ukuqinisekisa ukusetshenziswa okuvamile emkhakheni wokuthinta uwoyela owuketshezi.
Njengoba eseneminyaka ecishe ibe ngu-20 embonini yemishini yokukhipha izinto ezihlakaniphile, ubelokhu ephethe izindima ezibalulekile eJwell Machinery, okuhlanganisa noMphathi Jikelele kanye noSihlalo Ojikelezayo. Kusukela ngo-2024, uphathe izinkampani eziningi ezingaphansi kwakhe, eqhuba ukwanda kwebhizinisi kanye nokuthuthukiswa kwezimboni, ngenkathi ehola ukusungula izinto ezintsha ekukhiqizeni izinto ezihlakaniphile kanye nokukhula komhlaba wonke.
