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

chaza:

I-Ethylene vinyl acetate (EVA) iyi-copolymer eguquguqukayo eyakhiwe ngokuxuba ama-monomers e-ethylene kanye ne-vinyl acetate. Isilinganiso sokuqukethwe kwe-vinyl acetate (VA) ku-EVA singahluka kusuka ku-2% kuya ku-60%, okuvumela ukuthi kube ngokwezifiso izakhiwo zayo. I-EVA enokuqukethwe kwe-VA okuphansi, cishe okungu-3 wt%, ivame ukusetshenziswa ukuguqula i-polyethylene, kuyilapho ukwakheka okunokuqukethwe kwe-VA okuphezulu, okusukela ku-5 kuya ku-50 wt%, kuthola ukusetshenziswa ekukhiqizeni amafilimu anciphayo, ukupakisha ukudla, kanye nezicathulo, phakathi kokunye.

Imininingwane

I-Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer iyi-EVA foam modifier entsha ehlanzekile. Ingasetshenziswa njenge-Modifier EVA foam yokuhlala, i-Modifier Ingasetshenziswa njenge-Modifier EVA foam yokuhlala, i-Modifier EVA foam yemishini yokuzivikela, i-Modifier EVA foam yamathoyizi okwakha, i-Modifier EVA foam yama-shin guards, futhi ingasiza ekuthuthukiseni ubuchwepheshe be-Eva foaming running shoes. Inezinzuzo zokunciphisa ukushwabana kokushisa kwe-EVA foam, ukuthuthukisa ukuqina nokumelana nokuklwebheka, ukuthuthukisa ukuguqulwa kokucindezelwa kwezinto, nokukhuthaza izimbobo zebhamuza ukuthi zifane futhi zibe nkulu.

Izinzuzo Eziyinhloko

01

Thuthukisa ukunwebeka kwezinto ze-foam ze-EVA

Uma kuqhathaniswa ne-talcum powder noma i-anti-abrasion agent, i-Si-TPV inokuqina okungcono.
02

Thuthukisa ukugcwala kombala kwezinto ze-foam ze-EVA

Amanye amaqembu ku-Si-TPV angase asebenzisane nama-chromophores edayi, okwandisa ukugcwala kombala.
03

Nciphisa ukuncishiswa kokushisa kwezinto ze-foam ze-EVA

Ukunwebeka kwe-Si-TPV kusiza ukukhulula ukucindezeleka kwangaphakathi kwezinto ze-foam ze-EVA.
04

Thuthukisa ukumelana nokuguguleka kwezinto ze-foam ze-EVA

I-Si-TPV ingabamba iqhaza ekusabeleni kwe-ejenti yokuxhumanisa, okwandisa ubuningi bokuxhumanisa.
05

I-nucleation engafani

I-Si-TPV ihlakazeke ngokulinganayo ezintweni ze-foam ze-EVA, ezingasiza ekuthuthukisweni kweseli.
06

Nciphisa ukuguquguquka kokucindezelwa kwezinto ze-foam ze-EVA

I-Si-TPV inokumelana okuhle nokushisa okuphezulu nokuphansi, futhi ingathuthukisa ngasikhathi sinye ukuguquguquka kokucindezela kokushisa okuphezulu nokuphansi kwezinto ze-foam ze-EVA zokuqina okuphezulu.

Ukuqina Ukuqina

Ubuchwepheshe obuthuthukisiwe obungenazo izinyibilikisi, ngaphandle kwe-plasticizer, akukho uwoyela wokuthambisa, futhi awunaphunga.
Ukuvikelwa kwemvelo kanye nokusetshenziswa kabusha kwayo.
Itholakala ngezinhlobo ezihambisana nomthetho.

Umhlahlandlela Wokwenza Igwebu le-EVA

Uchungechunge lwe-Si-TPV 2250 lunezici zokuthintwa okuthambile okunobungani nesikhumba isikhathi eside, ukumelana okuhle kwamabala, akukho pulasitiki kanye nesithambisi esengeziwe, futhi akukho mvula ngemva kokusetshenziswa isikhathi eside, ikakhulukazi esetshenziselwa ukulungiselela izinto ze-EVA ezine-foam ezithambile nezinobungani nemvelo.

Ukusungula izinto ezintsha ze-EVA Foam (4)

Ngemva kokufaka i-Si-TPV 2250-75A, ubuningi bamaseli e-bubble e-EVA foam buyancipha kancane, udonga lwe-bubble luyaqina, bese i-Si-TPV ihlakazeka odongeni lwe-bubble, udonga lwe-bubble luba magebhugebhu.

Isicelo

Ngokufaka iziguquli ze-Si-TPV ezinqubweni zakho zokukhiqiza, amabhizinisi angakhiqiza izinto ze-foam ze-EVA ezinikezwe ukuqina okuthuthukisiwe, ukuqina, kanye nenduduzo, ezihambisana nezinhlelo zokusebenza ezahlukahlukene, kufaka phakathi izithende zezicathulo, imikhiqizo yenhlanzeko, izinto zokuzijabulisa kwezemidlalo, omata baphansi/be-yoga, nokuningi.

Ngokungafani nomlingani wayo we-semi-crystalline, i-polyethylene, ukwethulwa kwama-VA monomers kuphazamisa ukwakheka kwamakristalu ku-polymer chain, okuholela ekunciphiseni ubukristalu. Njengoba okuqukethwe kwe-VA kukhuphuka, i-EVA iba yi-amorphous kancane kancane, okuholela ezinguqukweni ezicini zayo zomzimba nezomshini. Ngenkathi amapharamitha afana nokunwebeka lapho kuphuka, izinga lokushisa lokushintsha kwengilazi, kanye nobuningi kukhuphuka ngokuqukethwe kwe-VA okuphezulu, okunye okufana namandla okunamathela, i-modulus, ubulukhuni, kanye nokushisa kokuncibilika kwehla. Kodwa-ke, naphezu kokuqina kwayo okuthuthukisiwe, i-EVA ingabonisa ukuntuleka kwamandla okudabuka, ukumelana nokuguguleka, kanye nesethi yokucindezela, ikakhulukazi ekusetshenzisweni okudinga ukuqina.

Ukuze kunqotshwe le mikhawulo, i-EVA ivame ukuhlanganiswa nama-raber noma ama-thermoplastic elastomers (ama-TPE), okuthuthukisa amandla okuthamba, ukumelana nokudabuka, ukumelana nokuklwebheka, kanye nokuqina kwamakhemikhali uma kuqhathaniswa ne-EVA emsulwa. Ukuhlanganisa i-EVA nama-TPE afana ne-thermoplastic polyurethane (TPU) noma i-polyolefin elastomers (POE) kuthuthukisa izakhiwo ze-viscoelastic futhi kusiza ekucubungulweni nasekusetshenzisweni kabusha. Ngaphezu kwalokho, ukuvela kwama-olefin block copolymers (OBC) kunikeza izici ze-elastomeric kanye nokumelana nokushisa okuphezulu. Isakhiwo esiyingqayizivele se-OBC, esakhiwe izingxenye eziqinile ezikristalukayo kanye nezingxenye ezithambile ezi-amorphous, senza ukusebenza okuphezulu ezinhlelweni ezahlukahlukene, ngezakhiwo zesethi yokucindezelwa ezifana ne-TPU ne-TPV.
Kodwa-ke, i-SILIKE Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer advanced iyi-modifier ye-elastomer esekelwe ku-vulcanizate thermoplastic Silicone. Uma kuqhathaniswa nezi-modifier ezifana ne-OBC ne-POE, Okuvelele Okubalulekile kwe-Si-TPV kufaka phakathi: ● Thuthukisa ukunwebeka kwezinto ze-foam ze-EVA ● Thuthukisa ukugcwala kombala wezinto ze-foam ze-EVA ● Nciphisa ukuncishiswa kokushisa kwezinto ze-foam ze-EVA ● Thuthukisa ukumelana nokuguguleka kwezinto ze-foam ze-EVA ● I-Si-TPV ingathuthukisa ngasikhathi sinye ukuguquguquka kokucindezela okuphezulu nokuphansi kwezinga lokushisa kwezinto ze-foam ze-EVA ezinobunzima obuphezulu.
