Izindaba - Xazulula Izinselele Ze-EVA Foam

Eminyakeni yamuva nje, imakethe yezicathulo zomhlaba wonke ibone ukugcwala, okwandisa ukuncintisana phakathi kwemikhiqizo ephakathi kuya kweyezinga eliphezulu. Ukugeleza okuqhubekayo kwemibono emisha kanye nobuchwepheshe ezicathulweni kuholele ekudingweni okukhulu kwezinto zokwenziwa kwegwebu embonini yokwenza izicathulo. Izinto zokwenziwa kwegwebu le-polymer ezisebenza kahle kakhulu sezibe yitshe lesisekelo lezixazululo eziningi zemikhiqizo yomkhiqizo wokugcina, ikakhulukazi emkhakheni wezicathulo zezemidlalo.

Izicathulo zezemidlalo ezijwayelekile zinezingxenye ezintathu eziyinhloko: i-top, i-midsole, kanye ne-outsole.

I-midsole ibalulekile ekuletheni ukugoba, ukugoba, kanye nokumuncwa kwamandla okushaya ngesikhathi semidlalo. Iqinisekisa ukuvikelwa kanye nomuzwa okhululekile, okwenza kube umphefumulo wezicathulo zemidlalo. Ubuchwepheshe bezinto ezibonakalayo kanye nobokugoba be-midsole buhlukanisa ubuchwepheshe obuyinhloko bemikhiqizo ehlukahlukene emikhulu.

I-EVA—Izinto Ezisetshenziswa Kakhulu Ze-Foam Zezicathulo:

I-ethylene-vinyl acetate copolymer (EVA) iyinto yokuqala ye-foam esetshenziswa ema-midsoles. I-Pure EVA foam ivame ukuba ne-rebound engu-40-45%, idlula izinto ezifana ne-PVC nerabha ngokuqina, kuhlanganiswe nezimfanelo ezifana nokukhanya okulula nokulula kokucutshungulwa.

Emkhakheni wezicathulo, izinqubo ze-EVA zokukhipha amagwebu amakhemikhali ngokuvamile zifaka izinhlobo ezintathu: ukukhupha amagwebu okukhulu okuyisicaba, ukukhupha amagwebu amancane okubunjiwe, kanye nokukhipha amagwebu okuxubene nge-injection.

Njengamanje, ukujikijela nge-cross-linking foam sekuyindlela eyinhloko ekucutshungulweni kwezinto zezicathulo.

Izinselele ze-EVA Foam:

Inkinga evamile ngala ma-foam e-EVA endabuko ukunwebeka kwawo okulinganiselwe, okuthinta ikhono lawo lokunikeza ukugoba kanye nokusekela okuhle kakhulu, ikakhulukazi ezicelweni ezifana nezicathulo zezemidlalo. Enye inselele evamile ukuba khona kwesethi yokucindezela kanye nokuncipha kokushisa ngokuhamba kwesikhathi, okuthinta ukuqina. Ngaphezu kwalokho, Ezicelweni lapho ukumelana nokushelela kanye nokumelana nokuklwebheka kubalulekile khona, i-foam ye-EVA yendabuko ingase ingahlangabezani nezindinganiso ezidingekayo.

Ukuze kuthuthukiswe izakhiwo zomzimba zemikhiqizo ye-foam ye-EVA, abakhiqizi bavame ukwethula izinto ezinwebekayo njenge-EPDM, i-POE, ama-OBC, kanye ne-TPE njenge-SEBS ezintweni zokusetshenziswa ze-EVA. Ukufakwa kwe-EPDM kwezakhiwo zerabha, i-POE yokwelula okuphezulu, ama-OBC ekristalini ethambile, i-TPE yokuguquguquka, njll., kuhlose ukufeza imigomo yokuguqulwa. Isibonelo, ngokungeza ama-elastomer e-POE, ukuqina kokubuyela emuva kwemikhiqizo kungakhushulwa kube ngu-50-55% noma ngaphezulu.

I-Foam EVA Yokusungula Izinto Ezintsha: I-Si-TPV Modifier Yekhwalithi Ephakeme Nokusebenza Okuthuthukisiwe

I-SILIKE Si-TPV iveza indlela ehlukile ku-EVA, ayigcini nje ngokubhekana nezinkinga zokusebenza kodwa futhi ihambisana nezinhlelo ezinobungani nemvelo. Ukwakheka kwayo okusha kanye nenqubo yokukhiqiza kunegalelo ekuqinisekiseni ukuthi imikhiqizo igcina ubuqotho bayo kanye nokusebenza kwayo isikhathi eside, okwenza ithembeke futhi iqine kakhudlwana, iqinisekise amazinga aphezulu omkhiqizo oqediwe.

I-Si-TPV (i-elastomer esekelwe ku-thermoplastic silicone) iyinto esetshenziswa kabusha engu-100% ye-elastomer, uma iqhathaniswa ne-OBC ne-POE, inciphisa kakhulu isethi yokucindezela kanye nesilinganiso sokuncipha kokushisa kwezinto ze-foam ze-EVA. Okugqamile kakhulu kuthuthukise ukuqina, ubumnene, ukumelana nokushelela, kanye nokumelana nokuguguleka, kunciphisa ukuguguleka kwe-DIN kusuka ku-580 mm.³kuya ku-179 mm³.

Ngaphezu kwalokho, i-Si-TPV ithuthukisa ukugcwala kombala kwezinto ze-foam ze-EVA. Lokhu kuphumelela kuvumela abakhiqizi ukuthi bakhiqize imikhiqizo ekhangayo ngaphandle kokuphazamisa ukusebenza.

Le Si-TPV njengoshintsho oluqanjiwe lwe-foam ye-EVA izuzisa ukukhiqizwa kwemikhiqizo ehlobene ne-EVA foam eduduzayo nehlala isikhathi eside njenge-midsoles, izinto zenhlanzeko, imikhiqizo yokuzilibazisa kwezemidlalo, phansi, omata be-yoga, nokuningi.

Thola Ikusasa Le-EVA Foam nge-SILIKE Si-TPV! Phakamisa imikhiqizo yakho ibe sezingeni eliphezulu lokusebenza nekhwalithi. Vula amandla e-Si-TPV modifier yethu eqhubekayo ukuze uthole amathuba angenakuqhathaniswa kuzinhlelo zakho zokusebenza ze-EVA foam.

Xhumana nathi namuhla ukuze uqale uhambo lokusungula izinto ezintsha futhi uchaze kabusha ukuthi yini engenzeka nge-foam ye-EVA!
