Iindaba-Sombulula imingeni ye-EVA Foam

Kwiminyaka yakutshanje, imarike yezihlangu yehlabathi ibone ukugcwala, iqinisa ukhuphiswano phakathi kweempawu ezikumgangatho ophezulu.Ukuthontelana okuqhubekayo kweengqikelelo ezintsha kunye nobuchwepheshe kwizihlangu kuqhube imfuno enkulu yezinto ezinogwebu kumzi-mveliso wokwenza izihlangu.Izinto zepolymer ezisebenza ngokuphezulu ziye zaba lilitye lembombo lezisombululo ezininzi zemveliso ye-terminal, ngakumbi kwicandelo lezihlangu zemidlalo.

Izihlangu zezemidlalo ezisemgangathweni zibandakanya iindawo ezintathu eziphambili: phezulu, i-midsole, kunye ne-outsole.

I-midsole ibalulekile ekuhambiseni i-cushioning, i-rebound, kunye nefuthe lokufunxa ngamandla ngexesha lezemidlalo.Iqinisekisa ukukhuselwa kunye nokuziva ukhululekile, okwenza kube ngumphefumlo wezicathulo zezemidlalo.Itekhnoloji yemathiriyeli kunye ne-foaming ye-midsole yahlula itekhnoloji ephambili yeempawu ezahlukeneyo ezinkulu.

I-EVA-Eyona nto yakudala isetyenzisiweyo yogwebu kwizihlangu:

I-Ethylene-vinyl acetate copolymer (i-EVA) yinto yokuqala ye-foam esetyenziswa kwi-midsoles.Igwebu elicocekileyo le-EVA lidla ngokuzidla ngokuphinda libuyele kwi-40-45%, izixhobo ezigqwesileyo ezifana ne-PVC kunye nerabha ekomeleleni, kudityaniswa neempawu ezinjengobunzima kunye nokucutshungulwa ngokulula.

Kwibala lezihlangu, iinkqubo ze-EVA's imichiza yogwebu ngokubanzi zibandakanya iindidi ezintathu: isiko esithe tyaba esinamagwebu amakhulu, ukungunda okunamagwebu amancinci, kunye nenaliti edibanisa ugwebu.

Okwangoku, i-injection cross-linking foaming ibe yeyona nkqubo iphambili ekusetyenzweni kwemathiriyeli yezihlangu.

Imingeni ye-EVA Foam:

Ingxaki eqhelekileyo ngala magwebu emveli e-EVA kukunyibilika kwawo okulinganiselweyo, okuchaphazela amandla abo okubonelela ngokucokisekileyo kunye nenkxaso, ngakumbi kwizicelo ezifana nezihlangu zemidlalo.Omnye umngeni oqhelekileyo kukwenzeka kwesethi yoxinzelelo kunye nokuncipha kwe-thermal ngokuhamba kwexesha, okuchaphazela ukuqina.Ngaphezu koko, kwizicelo apho ukuxhathisa ukutyibilika kunye nokuxhathisa kwe-abrasion kubaluleke kakhulu, igwebu le-EVA lemveli linokusilela ekufezekiseni imigangatho efunekayo.

Ukuphucula ngakumbi iipropathi ezibonakalayo zeemveliso zogwebu ze-EVA, abavelisi bahlala bezisa imathiriyeli enwebekayo efana ne-EPDM, i-POE, i-OBCs, kunye ne-TPE efana ne-SEBS kwimathiriyeli ekrwada ye-EVA.Ukufakwa kwe-EPDM kwiipropati zerabha, i-POE ye-elasticity ephezulu, i-OBCs ye-crystallinity ethambileyo, i-TPE yokuguquguquka, njl., ijolise ekufezekiseni iinjongo zokuguqulwa.Umzekelo, ngokongeza i-POE elastomers, ukomelela kwakhona kweemveliso kunokunyuswa ukuya kuma-50-55% okanye nangaphezulu.

Ukuveliswa kwe-EVA Foam: I-Si-TPV Modifier yoMgangatho oPhezulu kunye nokuSebenza okuPhuculo

I-SILIKE Si-TPV iveza enye indlela kwi-EVA, ayijongi kuphela imiba yokusebenza kodwa ihambelana namalinge e-eco-friendly.Ukuqulunqwa kwayo okutsha kunye nenkqubo yokuvelisa igalelo ekuqinisekiseni ukuba iimveliso zigcina ingqibelelo kunye nokusebenza kwazo kwixesha elongeziweyo, zizenza zithembeke ngakumbi kwaye zomelele.ukuqinisekisa amaxabiso aphezulu emveliso egqityiweyo.

I-Si-TPV (i-vulcanizate thermoplastic silicone-based elastomer) yimpahla ye-elastomer eyi-100% enokuphinda isetyenziswe, xa kuthelekiswa ne-OBC kunye ne-POE, iyancipha ngokuphawulekayo isethi yokunyanzeliswa kunye nesantya sokushisa sezinto ze-foam ze-EVA.Amanqaku angaphezulu aphucule ukuqina, ukuthamba, ukuchasana nokutyibilika, kunye nokumelana nokuqhawuka, ukunciphisa ukunxiba kwe-DIN ukusuka kwi-580 mm.³ukuya kwi-179 mm³.

Ukongeza, i-Si-TPV iphucula ukugcwala kombala wezinto zogwebu ze-EVA.Le mpumelelo ivumela abavelisi ukuba bavelise iimveliso ezibukekayo ngaphandle kokuphazamisa ukusebenza.

Le Si-TPV njengohlengahlengiso olutsha lwe-EVA ugwebu lunceda ukuveliswa kwentuthuzelo kunye nemveliso ehlala ihleli ye-EVA enxulumene nogwebu olunje nge-midsoles, izinto zococeko, iimveliso zokuzonwabisa kwezemidlalo, imigangatho, iimethi ze-yoga, kunye nokunye.

Fumanisa ikamva le-EVA Foam nge-SILIKE Si-TPV!Phakamisa iimveliso zakho kubude obutsha bokusebenza kunye nomgangatho.Khulula ukubanakho kwesiguquli sethu se-Si-TPV esiqhubela phambili samathuba angenakuthelekiswa nanto kwizicelo zakho zogwebu ze-EVA.
