Izindaba - Xazulula Izinselele ze-EVA Foam

Eminyakeni yakamuva, imakethe yezicathulo yomhlaba wonke ibone ukugcwala, kuqinisa ukuncintisana phakathi kwemikhiqizo esezingeni eliphezulu.Ukuthutheleka okuqhubekayo kwemiqondo emisha nobuchwepheshe ezicathulweni kuye kwaqhuba isidingo esikhulu sezinto ezikhiqiza amagwebu embonini yokwenza izicathulo.Izinto ze-polymer foam ezisebenza kahle seziphenduke isisekelo sezixazululo eziningi zomkhiqizo womkhiqizo, ikakhulukazi emkhakheni wezicathulo zezemidlalo.

Ipheya elijwayelekile lezicathulo zezemidlalo lihlanganisa izingxenye ezintathu eziyinhloko: engenhla, i-midsole, ne-outsole.

I-midsole ibalulekile ekuletheni i-cushioning, i-rebound, kanye nokumuncwa kwamandla okuthinta ngesikhathi semidlalo.Iqinisekisa ukuvikelwa kanye nomuzwa okhululekile, okwenza kube umphefumulo wezicathulo zezemidlalo.Ubuchwepheshe bezinto ezibonakalayo nobugwebu be-midsole buhlukanisa ubuchwepheshe obuyisisekelo bemikhiqizo emikhulu ehlukahlukene.

I-EVA—Isisetshenziswa Segwebu Sakuqala Esenziwe Ngezicathulo:

I-Ethylene-vinyl acetate copolymer (EVA) yinto yokuqala eyigwebu esetshenziswa kuma-midsoles.Igwebu le-EVA elihlanzekile ngokuvamile liziqhayisa ngokuphindaphinda okungama-40-45%, izinto ezidlula izinto ezifana ne-PVC nerabha eqinile, ehambisana nezimfanelo ezifana nokungasindi nokucutshungulwa kalula.

Emkhakheni wezicathulo, izinqubo ze-EVA zokukhihliza amagwebu kwamakhemikhali ngokuvamile zihlanganisa izinhlobo ezintathu: amagwebu ayisicaba ayisicaba, amagwebu amancane angaphakathi esikhunjeni, kanye negwebu elixhumanisa umjovo.

Njengamanje, igwebu elixhumanisa umjovo sekuyinqubo evamile ekucutshungulweni kwempahla yezicathulo.

Izinselelo ze-EVA Foam:

Inkinga evamile ngalawa magwebu e-EVA endabuko ukunwebeka kwawo okulinganiselwe, okuthinta ikhono lawo lokuhlinzeka ngokukhululeka nokusekelwa, ikakhulukazi ezinhlelweni ezifana nezicathulo zemidlalo.Enye inselele evamile ukuvela kwesethi yokucindezela kanye nokuncipha kokushisa ngokuhamba kwesikhathi, okuthinta ukuqina.Ngaphezu kwalokho, Ezisetshenziswayo lapho ukumelana nokushelela kanye nokumelana nokuhuzuka kubaluleke kakhulu, igwebu le-EVA lendabuko lingase liwelele ekuhlangabezaneni namazinga adingekayo.

Ukuze kuthuthukiswe izici ezibonakalayo zemikhiqizo yegwebu ye-EVA, abakhiqizi bavamise ukwethula izinto ezinwebekayo ezifana ne-EPDM, i-POE, ama-OBC, ne-TPE efana ne-SEBS kuzinto zokusetshenziswa ze-EVA.Ukufakwa kwe-EPDM yezakhiwo zenjoloba, i-POE yokunwebeka okuphezulu, ama-OBCs wekristalu elithambile, i-TPE yokuguquguquka, njll., ihlose ukufeza imigomo yokuguqulwa.Isibonelo, ngokungeza ama-elastomer e-POE, ukusimama kabusha kwemikhiqizo ngokuvamile kungakhushulwa ku-50-55% noma ngaphezulu.

Ukuqamba okusha kwe-EVA Foam: I-Si-TPV Modifier Yekhwalithi Ephezulu Nokusebenza Okuthuthukisiwe

I-SILIKE Si-TPV yethula enye indlela ku-EVA, ayigcini nje ngokubhekana nezinkinga zokusebenza kodwa futhi ihambisana nezinhlelo ezilungele imvelo.Ukwakheka kwayo okusha kanye nenqubo yokukhiqiza kunomthelela ekuqinisekiseni ukuthi imikhiqizo igcina ubuqotho nokusebenza kwayo phakathi nezikhathi ezinwetshiwe, okuyenza ithembeke futhi ihlale isikhathi eside.ukuqinisekisa amazinga aphezulu omkhiqizo oqediwe.

I-Si-TPV (i-vulcanizate thermoplastic silicone-based elastomer) iyimpahla ye-elastomer ekwazi ukugaywa kabusha engu-100%, Uma iqhathaniswa ne-OBC ne-POE, yehlisa ngokuphawulekayo isethi yokucindezelwa kanye nezinga lokushisa lokuncipha kwezinto ze-EVA foam.Okugqamile okwengeziwe kuthuthukise ukunwebeka, ukuthamba, ukumelana nokushelela, nokumelana nokuhuzuka, kunciphisa ukugqokwa kwe-DIN kusuka ku-580 mm³ngo 179mm³.

Ngaphezu kwalokho, i-Si-TPV ithuthukisa ukugcwala kombala kwezinto ze-EVA foam.Lokhu kuphumelela kuvumela abakhiqizi ukuthi bakhiqize imikhiqizo ebukekayo ngaphandle kokuyekethisa ekusebenzeni.

Le Si-TPV njengesilungisi sokusungula se-EVA foam izuzisa ukukhiqizwa kokunethezeka kanye nemikhiqizo ehlala njalo ehlobene ne-EVA ekhihliza amagwebu njengama-midsoles, izinto zokuhlanzeka, imikhiqizo yezemidlalo yokuzilibazisa, phansi, omata be-yoga, nokuningi.

Zitholele Ikusasa Le-EVA Foam nge-SILIKE Si-TPV!Phakamisa imikhiqizo yakho ezindaweni eziphakeme zokusebenza nekhwalithi.Vula amandla esilungisi sethu se-Si-TPV esiqhubekayo ukuze uthole amathuba angenakuqhathaniswa ezinhlelweni zakho zokusebenza zegwebu le-EVA.

Xhumana nathi namuhla ukuze uqale uhambo lokuqamba izinto ezintsha futhi uchaze kabusha ukuthi yini engenzeka ngegwebu le-EVA!
