I-Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer ithuthukisa ubuchwepheshe begwebu be-EVA

chaza:

I-Ethylene vinyl acetate (EVA) iyi-copolymer eguquguqukayo eyakhiwe ngokuhlanganisa i-ethylene ne-vinyl acetate monomers. Ingxenye yokuqukethwe kwe-vinyl acetate (VA) ku-EVA ingahluka kusuka ku-2% kuya ku-60%, okuvumela ukwenziwa ngokwezifiso kwezakhiwo zayo. I-EVA enokuqukethwe kwe-VA ephansi, cishe ku-3 wt%, ivame ukusetshenziselwa ukuguqula i-polyethylene, kuyilapho izingoma ezinokuqukethwe okuphezulu kwe-VA, kusukela ku-5 kuya ku-50 wt%, zithola izinhlelo zokusebenza ekukhiqizeni amafilimu ashwabenekayo, ukupakishwa kokudla, nezicathulo, phakathi kokunye.

Imininingwane Yomkhiqizo
Omaka bomkhiqizo

I-Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer iyisilungisi segwebu esihlanzekile esihlanzekile se-EVA. ingasetshenziswa njengegwebu le-Modifier EVA yokuhlala, i-Modifier Ingasetshenziswa njengegwebu le-Modifier EVA yokuhlala, igwebu le-Modifier EVA lezinto zokuzivikela, igwebu le-Modifier EVA lamathoyizi okwakha, igwebu le-Modifier EVA labaqaphi beshin, futhi lingasiza ukuthuthukiswa kokuthuthukiswa kobuchwepheshe be-Eva foaming running shoes. Inezinzuzo zokunciphisa ukushwabana okushisayo kwegwebu le-EVA, ukuthuthukisa ukuqina nokumelana nemihuzuko, ukuthuthukisa ukuwohloka kokucindezelwa kwezinto, nokuthuthukisa izimbobo zebhamuza ukuthi zifane futhi ziminyene.

Ngokungafani nozakwabo we-semi-crystalline, i-polyethylene, ukwethulwa kwama-monomers e-VA kuphazamisa ukwakheka kwamakristalu ochungechungeni lwe-polymer, okuholela ekunciphiseni kwekristalu. Njengoba okuqukethwe kwe-VA kwanda, i-EVA iba i-amorphous kancane kancane, okuholela ekushintsheni kwezakhiwo zayo ezingokomzimba nezomshini. Ngenkathi amapharamitha afana nobude ngesikhathi sekhefu, izinga lokushisa lokushintsha kwengilazi, nokuminyana kwenyuka ngokuqukethwe okuphezulu kwe-VA, amanye anjengamandla aqinile, i-modulus, ubulukhuni, nokwehla kwezinga lokushisa elincibilikayo. Kodwa-ke, naphezu kokunwebeka kwayo okuthuthukisiwe, i-EVA ingase ibonise ukuntula amandla okudabula, ukumelana nokugqoka, kanye nesethi yokucindezela, ikakhulukazi ezinhlelweni ezidinga ukuqina.

Ukuze unqobe le mikhawulo, i-EVA ivame ukuhlanganiswa nama-rubber noma ama-thermoplastic elastomers (TPEs), ithuthukisa amandla aqinile, ukumelana nezinyembezi, ukumelana nokuhuzuka, nokuqina kwamakhemikhali uma kuqhathaniswa ne-EVA emsulwa. Ukuhlanganisa i-EVA nama-TPE afana ne-thermoplastic polyurethane (TPU) noma ama-polyolefin elastomers (POE) kuthuthukisa izici ze-viscoelastic futhi kusiza ukucutshungulwa kanye nokugaywa kabusha. Ukwengeza, ukuvela kwe-olefin block copolymers (OBC) kunikeza izici ze-elastomeric kanye nokumelana nokushisa okuphezulu. Isakhiwo esiyingqayizivele se-OBC, esihlanganisa amasegimenti aqinile acwebezelayo kanye namasegimenti athambile e-amorphous, anika amandla ukusebenza okuphakeme ezinhlelweni ezihlukahlukene zokusebenza, ngesethi yokucindezelwa kwezakhiwo eziqhathaniswa ne-TPU ne-TPV.
Nokho, i-SILIKE Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer advances iyi-groundbreaking vulcanizate thermoplastic Silicone-based elastomer modifier. Uma kuqhathaniswa nezilungisi ezifana ne-OBC ne-POE, Okuvelele Okubalulekile kwe-Si-TPV kufaka phakathi: ● Ukuthuthukisa ukunwebeka kwezinto ezisetshenziswayo zegwebu ze-EVA ● Thuthukisa ukugcwala kombala kwezinto zegwebu ze-EVA ● Yehlisa ukushwabana kokushisa kwezinto zegwebu le-EVA ● Thuthukisa ukuguga kokungezwani nokuhuzuka. yezinto ezisetshenziswayo zegwebu ze-EVA ● I-Si-TPV ingathuthukisa kanyekanye ukuwohloka kokucindezelwa okuphezulu nokuphansi kwezinga lokushisa lokuqina okuphezulu kwempahla yegwebu ye-EVA

Isicelo

Ngokuhlanganisa izilungisi ze-Si-TPV ezinqubweni zakho zokukhiqiza, amabhizinisi angakhiqiza izinto zegwebu ze-EVA ezinikezwe ukuqina okuthuthukisiwe, ukuqina, nokunethezeka, ezihlinzekela izinhlelo zokusebenza ezahlukahlukene, okuhlanganisa amasoli ezicathulo, imikhiqizo yenhlanzeko, izinto zokungcebeleka zezemidlalo, omatila bephansi/yoga, nokunye. .
