Ethylene-vinyl acetate copolymer CAS 24937-78-8 (EVA) e na le mefuta e mengata ea lits'ebetso, tse latelang ke libaka tsa eona tsa mantlha tsa ts'ebeliso:
Tšimo e tšesaane ea filimi
Filimi ea temo: EVA e na le phetiso e ntle ea leseli, e boloka mocheso le ho hanyetsa boemo ba leholimo, 'me hangata e sebelisoa tlhahisong ea filimi ea temo. E ka boloka mocheso le mongobo ka katleho ka har'a sethopo sa limela, ea khothaletsa kholo ea lijalo, le ho lelefatsa bophelo ba tšebeletso ea filimi.
Filimi ea ho paka: Filimi ea EVA e na le ho tenyetseha ho hoholo, ponaletso le ho hanyetsa ho phunyeha, e loketse ho paka lihlahisoa tse fapaneng, tse kang lijo, litlhoko tsa letsatsi le letsatsi, jj. 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, ho tenyetseha ho hoholo, boima bo bobebe, ho hanyetsa ho tsofala, jj., ke thepa e loketseng bakeng sa ho etsa sole. Sole e entsoeng ka EVA e phutholohile ho e apara, e na le ts'ebetso e ntle ea ho monya tšisinyeho, 'me e ka fokotsa mokhathala oa maoto.
Ka Holimo: EVA e ka boela ea sebelisoa ho etsa thepa e ka holimo, e fana ka ho ama ho bonolo le ho hema hantle, e leng se etsang hore lieta li phutholohe haholoanyane 'me li be ntle.
Tšimo ea sekhomaretsi e chesang e qhibilihang
Sekhomaretsi se chesang sa ho qhibiliha sa EVA: se na le melemo ea ho ba le ho teteana ho matla, ho fola kapele, ho hanyetsa mocheso o tlase, jj., se sebelisoa haholo ho paketeng, ho tlameng, tlhahisong ea thepa ea ka tlung le liindastering tse ling. Se ka sebelisoa ho kopanya pampiri, lehong, polasetiki le thepa e 'ngoe, se bonolo ho se sebelisa, se ka ntlafatsa katleho ea tlhahiso.
Terata le tšimo ea cable
Lera la ho thibela ho ruruha: EVA e na le ts'ebetso e ntle ea ho thibela ho ruruha, ho hanyetsa metsi le ho hanyetsa ho bola ha lik'hemik'hale, e ka sebelisoa e le thepa ea lera la ho thibela ho ruruha bakeng sa terata le thapo, e ka sireletsa terata le thapo ka katleho tšusumetsong ea tikoloho ea kantle, ho netefatsa polokeho le botšepehi ba phetiso ea motlakase.
Selao: EVA e ka boela ea sebelisoa ho etsa selao sa terata le thapo, e fana ka tšireletso ea mechini le ts'ebetso ea ho thibela botsofali, e eketsa bophelo ba tšebeletso ea terata le thapo.
Masimo a mang
Dipapadi: EVA e bonolo, ha e na chefo, ha e na monko le litšobotsi tse ling, hangata e sebelisoa ho etsa lintho tsa ho bapala, tse kang libolo tsa bana tsa ho bapala, li-puzzle, jj., ho netefatsa polokeho le boiketlo ba tšebeliso ea bana.
Thepa ea lipapali: E boetse e sebelisoa haholo linthong tsa lipapali, tse kang MATS ea lipapali, MATS ea yoga, jj., tseo bonolo le ho tenyetseha ha tsona li ka fanang ka tšehetso e ntle le phello ea ho roka.
Lihlahisoa tsa foam: Foam ea EVA e na le boima bo bobebe, e bonolo, e boloka mocheso, e thibela molumo le thepa e meng, e ka sebelisoa ho etsa mefuta e fapaneng ea lihlahisoa tsa foam.
