I-Si-TPV eguquguqukayo ivulcanizate ye-thermoplastic silicone-based elastomer iqhubela phambili itekhnoloji yogwebu ye-EVA

chaza:

I-Ethylene vinyl acetate (EVA) yicopolymer eguquguqukayo eyenziwe ngokuxuba i-ethylene kunye ne-vinyl acetate monomers. Umlinganiselo we-vinyl acetate (VA) umxholo kwi-EVA unokuhluka kwi-2% ukuya kwi-60%, evumela ukulungelelaniswa kweempawu zayo. I-EVA enomxholo ophantsi we-VA, malunga ne-3 wt%, isetyenziswa ngokuqhelekileyo ukuguqula i-polyethylene, ngelixa iingoma ezinomxholo ophezulu we-VA, ukusuka kwi-5 ukuya kwi-50 wt%, zifumane izicelo ekuveliseni iifilimu ezinciphayo, ukupakishwa kokutya, kunye nezihlangu, phakathi kwabanye.

Iinkcukacha zeMveliso
Iithegi zeMveliso

I-Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer yinto entsha ecocekileyo ecocekileyo ye-EVA isilungisi sogwebu. Inokusetyenziswa njenge-Modifier EVA foam yokuhlalisa, i-Moderifier Ingasetyenziswa njenge-Modifier EVA foam yokuhlala, i-Modifier EVA foam yezixhobo zokukhusela, i-Modifier EVA foam yezinto zokudlala zokwakha, i-Modifier EVA foam ye-shin guards, kwaye inokwenza lula ukuphuculwa kwe-Eva egwebuyo eqhuba izihlangu zokuphucula iteknoloji. Ineenzuzo zokunciphisa i-thermal shrinkage ye-EVA foam, ukuphucula ukuqina kunye nokuxhatshazwa kwe-abrasion, ukuphucula ukunyanzeliswa kwe-deformation yezinto eziphathekayo, kunye nokukhuthaza imingxunya ye-bubble ukuba ibe yinto efanayo kwaye ixinene.

Ngokungafaniyo nomlingani wayo we-semi-crystalline, i-polyethylene, ukungeniswa kwe-VA monomers kuphazamisa ukubunjwa kweekristale kwikhonkco ye-polymer, okubangelwa ukunciphisa i-crystallinity. Njengoko umxholo we-VA usanda, i-EVA iba yi-amorphous ngokuqhubekayo, ekhokelela kutshintsho kwizakhiwo zayo zomzimba kunye nezomatshini. Ngelixa iiparamitha zifana nobude ngexesha lekhefu, ubushushu beglasi yokutshintsha, kunye noxinzelelo lonyuka ngomxholo ophezulu we-VA, ezinye ezinje ngokuqina kokuqina, imodyuli, ubulukhuni, kunye nokuncibilika kweqondo lobushushu. Nangona kunjalo, ngaphandle kokuqina kwayo okuphuculweyo, i-EVA inokubonisa intsilelo kumandla okukrazula, ukuxhathisa, kunye neseti yoxinzelelo, ngakumbi kwizicelo ezifuna ukomelela.

Ukoyisa le mida, i-EVA ihlala idityaniswa neerubha okanye i-thermoplastic elastomers (i-TPEs), iphucula amandla okuqina, ukuchasana nokukrazula, ukuxhathisa i-abrasion, kunye nokomelela kweekhemikhali xa kuthelekiswa ne-EVA esulungekileyo. Ukudibanisa i-EVA kunye nee-TPE ezifana ne-thermoplastic polyurethane (TPU) okanye i-polyolefin elastomers (POE) iphucula iimpawu ze-viscoelastic kwaye iququzelele ukusetyenzwa kunye nokuhlaziywa kwakhona. Ukongeza, ukuvela kwe-olefin block copolymers (OBC) inikezela ngeempawu ze-elastomeric kunye nokumelana nobushushu obuphezulu. Ulwakhiwo olukhethekileyo lwe-OBC, oluquka amacandelo alukhuni acwebezelayo kunye namacandelo athambileyo amorphous, yenza ukuba ukusebenza okuphezulu kusebenze kwizicelo ezahlukeneyo, kunye neempawu zokuxinzelela ezithelekiseka ne-TPU kunye ne-TPV.
Nangona kunjalo, i-SILIKE Si-TPV eguquguqukayo ivulcanizate i-thermoplastic silicone-based elastomer advances yi-groundbreaking vulcanizate thermoplastic Silicone-based elastomer modifier. Xa kuthelekiswa nezilungisi ezifana ne-OBC kunye ne-POE, amagqabantshintshi aPhambili e-Si-TPV aquka: ● Ukuphucula ukunwebeka kwemathiriyeli yogwebu ye-EVA ● Ukuphucula ukugcwala kombala wemathiriyeli yogwebu ye-EVA ● Nciphisa ukushwabana kobushushu bemathiriyeli yogwebu ye-EVA ● Ukuphucula ukuxhathisa okuchasene nogwebu. yemathiriyeli yogwebu ye-EVA ● I-Si-TPV inokuphucula ngaxeshanye ubushushu obuphezulu kunye nobushushu obuphantsi kobulukhuni obuphezulu bemathiriyeli yogwebu ye-EVA.

Isicelo

Ngokubandakanya izilungisi ze-Si-TPV kwiinkqubo zakho zokuvelisa, amashishini anokuvelisa izixhobo zogwebu ze-EVA ezinikwe ukomelela okongeziweyo, ukuqina, kunye nentuthuzelo, ukulungiselela usetyenziso olwahlukeneyo, kubandakanya neesuti zezihlangu, iimveliso zococeko, izinto zokuzonwabisa ezemidlalo, umgangatho / iimethi zeyoga, kunye nokunye. .

EVA ukugwebu Guide
