Sebenzisa lezi zindlela eziyisi-7 ukuhlonza i-TPE ne-TPU!

I-TPE ikhuluma kabanzi igama elijwayelekile lawo wonke ama-thermoplastic elastomer.Ihlukaniswa kanje:

Kodwa lokho okuvame ukubizwa nge-TPE kuyinhlanganisela yamafutha e-SEBS/SBS+PP+naphthenic+calcium carbonate+auxiliaries.Ibizwa nangokuthi ipulasitiki ethambile enobungani bemvelo embonini, kepha kwesinye isikhathi ibizwa nge-TPR (ivame ukubizwa ngokuthi eZhejiang naseTaiwan) ).I-TPU, ebizwa nangokuthi i-polyurethane, inezinhlobo ezimbili: uhlobo lwe-polyester nohlobo lwe-polyether.

I-TPE ne-TPU zombili yizinto ze-thermoplastic ezinokunwebeka kwerabha.Izinto ze-TPE ne-TPU ezinobunzima obufanayo kwesinye isikhathi kungaba nzima ukuhlukanisa phakathi kwe-TPE ne-TPU ngokuvele uzibheke ngeso lenyama.Kodwa ngokuqala ngemininingwane, sisengakwazi ukuhlaziya umehluko nomehluko phakathi kwe-TPE ne-TPU ezicini eziningi.

1.Ukungafihli

Ukucaca kwe-TPU kungcono kunokwe-TPE, futhi akulula ukunamathela njenge-TPE esobala.

2. Isilinganiso

Ingxenye ye-TPE iyahlukahluka kakhulu, kusukela ku-0.89 kuya ku-1.3, kuyilapho i-TPU isukela ku-1.0 kuya ku-1.4.Eqinisweni, phakathi nokusetshenziswa kwazo, ngokuyinhloko zivela ngendlela yezingxube, ngakho amandla adonsela phansi athile ashintsha kakhulu!

3.Ukumelana nowoyela

I-TPU inokumelana nowoyela okuhle, kodwa kunzima ukuthi i-TPE imelane nowoyela.

4.Ngemva kokushiswa

I-TPE inephunga elimnandi elilula lapho kusha, futhi intuthu evuthayo incane futhi ilula.Ukushiswa kwe-TPU kunephunga elithile elibabayo, futhi kunomsindo wokuqhuma omncane lapho usha.

5.Izakhiwo zemishini

Ukunwebeka kwe-TPU kanye nezakhiwo zokululama ezinwebekayo (ukumelana ne-flexion nokumelana nokukhasa) zingcono kune-TPE.

Isizathu esiyinhloko ukuthi ukwakheka kwezinto ze-TPU kuyisakhiwo se-polymer homogeneous futhi singokwesigaba se-polymer resin.I-TPE ingxubevange enesakhiwo esinezigaba eziningi esihlanganiswe yinhlanganisela yezingxenye eziningi.

Ukucutshungulwa kwe-TPE yokuqina okuphezulu kuthambekele ekuguqukeni komkhiqizo, kuyilapho i-TPU ikhombisa ukunwebeka okuhle kakhulu kuzo zonke izigaba zobulukhuni, futhi umkhiqizo akulula ukuwukhubaza.

6.Ukumelana nezinga lokushisa

I-TPE ingu -60 degrees Celsius ~ 105 degrees Celsius, i-TPU ingu -60 degrees Celsius ~ 80 degrees Celsius.

7.Ukubukeka nokuzizwa

Kweminye imikhiqizo ehlanganiswe ngokweqile, imikhiqizo eyenziwe nge-TPU inomuzwa onzima nokumelana nokungqubuzana okuqinile;kuyilapho imikhiqizo eyenziwe nge-TPE inomuzwa obucayi futhi othambile nokusebenza kokungqubuzana okubuthakathaka.

Ukufingqa, zombili i-TPE ne-TPU ziyizinto ezithambile futhi zinokunwebeka okuhle kwerabha.Uma kuqhathaniswa, i-TPE inhle kakhulu ngokuya ngenduduzo ethintekayo, kuyilapho i-TPU ikhombisa ukunwebeka okuhle kakhulu namandla.
