Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) e na le mefuta e mengata ea likopo, tse latelang ke libaka tsa eona tse ka sehloohong tsa kopo:
Sebaka sa lifilimi tse tšesaane
Filimi ea temo: EVA e na le phetiso e ntle ea leseli, ho boloka mocheso le ho hanyetsa boemo ba leholimo, 'me hangata e sebelisoa ho hlahisa filimi ea temo. E ka atleha ho boloka mocheso le mongobo ka sethopo, ho khothalletsa kholo ea lijalo, le ho lelefatsa bophelo ba tšebeletso ea filimi.
Filimi ea liphutheloana: Filimi ea EVA e na le ho feto-fetoha ha maemo, ho pepeseha le ho hanyetsa ho phunya, ho loketse ho paka lihlahisoa tse sa tšoaneng, tse kang lijo, litlhoko tsa letsatsi le letsatsi, joalo-joalo E ka fana ka ts'ebetso e ntle ea tšireletso ha e ntse e bontša ponahalo ea sehlahisoa.
Tšimo ea thepa ea lieta
Sole: EVA e na le litšobotsi tsa bonolo, elasticity e ntle, boima bo bobebe, ho hanyetsa ho roala, joalo-joalo, ke thepa e loketseng ho etsa sole. Sole e entsoeng ka EVA e phutholohile ho roala, e na le ts'ebetso e ntle ea ho monya hamonate, 'me e ka fokotsa mokhathala oa maoto.
Holimo: EVA e ka boela ea sebelisoa ho etsa lisebelisoa tse ka holimo, ho fana ka ho ama ka bonolo le ho phefumoloha hantle, ho etsa lieta hore li phutholohe le tse ntle.
Sebaka sa sekhomaretsi se chesang se qhibiliha
EVA hot melt adhesive: e na le melemo ea viscosity e matla, ho folisa ka potlako, ho hanyetsa mocheso o tlase, joalo-joalo, e sebelisoa haholo ho paka, ho tlama, ho etsa thepa ea ka tlung le liindasteri tse ling. E ka sebelisoa ho kopanya pampiri, lehong, polasetiki le lisebelisoa tse ling, tse bonolo ho sebetsa, li ka ntlafatsa katleho ea tlhahiso.
Sebaka sa mohala le mohala
Insulation layer: EVA e na le ts'ebetso e ntle ea ho ts'oara, ho hanyetsa metsi le k'hemik'hale ea kutu ea lik'hemik'hale, e ka sebelisoa e le lisebelisoa tse sireletsang terata le thapo, e ka sireletsa terata le thapo ka katleho tšusumetsong ea tikoloho ea kantle, ho netefatsa polokeho le ts'epo ea phetisetso ea matla.
Sheath: EVA e ka boela ea sebelisoa ho etsa sheath bakeng sa terata le thapo, ho fana ka tšireletso ea mochini le ts'ebetso e khahlanong le botsofali, ho lelefatsa bophelo ba ts'ebeletso ea terata le thapo.
Libaka tse ling
Lintho tsa ho bapala: EVA e bonolo, ha e chefo, ha e na monko le litšobotsi tse ling, hangata e sebelisetsoa ho etsa lintho tsa ho bapala, tse kang libolo tsa bana, li-puzzle, joalo-joalo, ho netefatsa polokeho le boiketlo ba tšebeliso ea bana.
Thepa ea lipapali: E boetse e sebelisoa haholo ho thepa ea lipapali, tse kang lipapali tsa MATS, yoga MATS, joalo-joalo, tseo bonolo le elasticity ea tsona li ka fanang ka ts'ehetso e ntle le phello ea cushioning.
Lihlahisoa tsa foam: Foam ea EVA e na le boima bo bobebe, e bonolo, e boloka mocheso, e thibela molumo le lisebelisoa tse ling, e ka sebelisoa ho etsa lihlahisoa tse sa tšoaneng tsa foam.
