Amakuru - Gukemura ibibazo bya EVA Foam

Mu myaka yashize, isoko ryinkweto zisi kwisi ryuzuyemo kwiyuzuzamo, bikazamura irushanwa hagati yikirango cyo hagati nacyo cyo hejuru. Kwiyongera kwimyumvire nubuhanga bushya mubirato byinkweto byatumye abantu benshi bakeneye ibikoresho byinshi mu nganda zinkweto. Ibikoresho byinshi-polymer yibikoresho byahindutse urufatiro rwibicuruzwa byinshi bya terefone, cyane cyane murwego rwimikino yimikino.

Inkweto zisanzwe za siporo zigizwe nibice bitatu byingenzi: hejuru, midsole, na outsole.

Midsole ningirakamaro mugutanga umusego, kwisubiraho, ningaruka zo kwinjiza imbaraga mugihe cya siporo. Irinda uburinzi no kumva neza, ikagira ubugingo bwinkweto za siporo. Tekinoroji yibikoresho na furo ya midsole itandukanya tekinoroji yibanze yibirango bitandukanye.

EVA - Ibikoresho Byakoreshejwe Byambere Byakoreshejwe Inkweto:

Ethylene-vinyl acetate copolymer (EVA) nibikoresho byambere byifuro bikoreshwa muri midole. Ifuro ryiza rya EVA risanzwe ryiyongera kuri 40-45%, rirenga ibikoresho nka PVC na reberi mukwihangana, hamwe nibiranga nkibyoroshye kandi byoroshye gutunganya.

Mu murima winkweto, uburyo bwa EVA bwimiti ifata ifuro muri rusange harimo ubwoko butatu: gakondo nini nini cyane, ifuro ritoya, hamwe no gutera inshinge.

Kugeza ubu, gutera inshinge-guhuza ifuro byahindutse inzira nyamukuru mugutunganya inkweto.

Ibibazo bya EVA Foam:

Ikibazo gikunze kugaragara hamwe naya mafuti gakondo ya EVA nubushobozi buke buke, bigira ingaruka kubushobozi bwabo bwo guterana neza no gushyigikirwa, cyane cyane mubisabwa nkinkweto za siporo. Iyindi mbogamizi isanzwe ni ukubaho kwikuramo gushiraho no kugabanuka kwubushyuhe bwigihe, bigira ingaruka kumara igihe. Byongeye kandi, Mubisabwa aho kunyerera kunyerera no kurwanya abrasion birakomeye, impumu gakondo ya EVA irashobora kutuzuza ibisabwa.

Kugirango turusheho kunoza imiterere yibicuruzwa bya EVA ifuro, abayikora bakunze kwinjiza ibikoresho byoroshye nka EPDM, POE, OBCs, na TPE nka SEBS mubikoresho fatizo bya EVA. Kwinjizamo EPDM kumitungo ya reberi, POE kuri elastique yo hejuru, OBCs ya kristu yoroheje, TPE kugirango ihindurwe, nibindi, igamije kugera ku ntego zo guhindura. Kurugero, wongeyeho POE elastomers, kwihanganira ibicuruzwa bishobora kwiyongera kugeza kuri 50-55% cyangwa birenze.

Guhanga udushya EVA Foam: Si-TPV Guhindura ubuziranenge no Kuzamura imikorere

SILIKE Si-TPV itanga ubundi buryo muri EVA, ntabwo ikemura ibibazo byimikorere gusa ahubwo ihuza nibikorwa byangiza ibidukikije. Ibikorwa byayo bishya hamwe nibikorwa byumusaruro bigira uruhare mugukora ibishoboka kugirango ibicuruzwa bigumane ubunyangamugayo n'imikorere mugihe kinini, bigatuma byizewe kandi biramba. kwemeza igipimo cyibicuruzwa byarangiye.

Si-TPV (vulcanizate thermoplastique silicone ishingiye kuri elastomer) ni ibikoresho bya elastomer 100% byongera gukoreshwa, Ugereranije na OBC na POE, bigabanya cyane uburyo bwo guhunika no kugabanya ubushyuhe bwibikoresho bya EVA ifuro. Ibindi bintu byingenzi byagaragaye byateje imbere ubworoherane, ubworoherane, kurwanya kunyerera, no kurwanya abrasion, kugabanya kwambara DIN kuva kuri 580 mm³kugeza kuri mm 179³.

Mubyongeyeho, Si-TPV yongerera ibara ryinshi ryibikoresho bya EVA. Iterambere ryemerera ababikora gukora ibicuruzwa bikurura amashusho bitabangamiye imikorere.

Iyi Si-TPV nkuguhindura udushya kuri EVA ifuro yunguka umusaruro wibintu byiza kandi biramba bya EVA bifitanye isano nifuro nka midole, ibikoresho by isuku, ibicuruzwa byo kwidagadura siporo, amagorofa, yoga yoga, nibindi byinshi.

Menya Kazoza ka EVA Foam hamwe na SILIKE Si-TPV! Uzamure ibicuruzwa byawe murwego rwo hejuru rwimikorere nubuziranenge. Kurekura ubushobozi bwa Si-TPV igenda itera imbere kubishoboka bitagereranywa mubikorwa bya EVA ifuro.

Twandikire uyu munsi kugirango dutangire urugendo rwo guhanga udushya hanyuma usobanure ibishoboka hamwe na EVA ifuro!
