Litaba - Rarolla Mathata a EVA Foam

Lilemong tsa morao tjena, 'maraka oa lefats'e oa lieta o bile le tlholisano e ntseng e eketseha har'a lihlahisoa tsa maemo a holimo ho isa ho tse holimo.Keketseho e sa khaotseng ea mehopolo le mahlale a macha a lieta a tsamaisitse tlhokahalo e kholo ea lisebelisoa tse phophomang indastering ea ho etsa lieta.Lisebelisoa tsa foam tse sebetsang hantle haholo li fetohile motheo oa litharollo tse ngata tsa lihlahisoa tsa brand, haholo-holo lekaleng la lieta tsa lipapali.

Lieta tse tloaelehileng tsa lieta tsa lipapali li na le likarolo tse tharo tse kholo: e ka holimo, ea midsole le ea outsole.

Midsole e bohlokoa ho faneng ka cushioning, rebound, le ho monya matla nakong ea lipapali.E tiisa tšireletso le boikutlo bo botle, ho etsa hore e be moea oa lieta tsa lipapali.Theknoloji ea thepa le e phophomang ea midsole e khetholla mahlale a mantlha a mefuta e fapaneng e meholo.

EVA—Sesebediswa sa Pele se Sebedisitsweng sa Foam bakeng sa Lieta:

Ethylene-vinyl acetate copolymer (EVA) ke thepa ea pele ea foam e sebelisoang li-midsoles.Foam e hloekileng ea EVA hangata e ithorisa ka 40-45%, lisebelisoa tse fetang tse joalo ka PVC le rabara e tsitsitseng, e kopantsoeng le litšoaneleho tse kang bobebe le boiketlo ba ts'ebetso.

Lebaleng la lieta, lits'ebetso tsa EVA tsa ho phophoma ka lik'hemik'hale ka kakaretso li kenyelletsa mefuta e meraro: foam e kholo ea setso, ho phophoma ha mapheo a manyane a ka har'a hlobo, le ho phophoma ka ente.

Hona joale, ho hlahisa lekobo la ente e se e le mokhoa o ka sehloohong oa ho lokisa thepa ea lieta.

Mathata a EVA Foam:

Bothata bo tloaelehileng ka liforomo tsena tsa setso tsa EVA ke elasticity ea bona e fokolang, e amang bokhoni ba bona ba ho fana ka ts'ehetso e nepahetseng, haholo lits'ebetsong tse kang lieta tsa lipapali.Phephetso e 'ngoe e tloaelehileng ke ho ba teng ha compression set le ho fokotseha ha mocheso ha nako e ntse e ea, ho ama ho tšoarella.Ho feta moo, lits'ebetsong moo ho hanyetsa ho thellang le ho hanyetsa abrasion ho leng bohlokoa, foam ea setso ea EVA e ka 'na ea haelloa ke ho finyella litekanyetso tse hlokahalang.

Ho ntlafatsa le ho feta thepa ea 'mele ea lihlahisoa tsa foam tsa EVA, bahlahisi ba atisa ho hlahisa lisebelisoa tse otlolohileng tse kang EPDM, POE, OBCs, le TPE tse kang SEBS ho thepa ea EVA.Ho kenyelletsoa ha EPDM bakeng sa thepa ea rabara, POE bakeng sa elasticity e phahameng, OBCs bakeng sa crystallinity e bonolo, TPE bakeng sa ho feto-fetoha ha maemo, joalo-joalo, e ikemiselitse ho finyella lipakane tsa phetoho.Mohlala, ka ho kenyelletsa li-elastomer tsa POE, matla a ho tiea ha lihlahisoa hangata a ka eketsoa ho 50-55% kapa ho feta.

Popontšo ea EVA Foam: Si-TPV Modifier bakeng sa Boleng bo Phahameng le Ts'ebetso e Ntlafetseng

SILIKE Si-TPV e hlahisa mokhoa o mong ho EVA, ha e bue feela ka litaba tsa ts'ebetso empa hape e tsamaellana le boikitlaetso ba tikoloho.Sebopeho sa eona se secha le ts'ebetso ea tlhahiso li kenya letsoho ho netefatseng hore lihlahisoa li boloka botšepehi le ts'ebetso ea tsona ka nako e telele, ho etsa hore li tšepahale le ho tšoarella.ho netefatsa litefiso tse phahameng tsa sehlahisoa se felileng.

Si-TPV (vulcanizate thermoplastic silicone-based elastomer) ke 100% e ka sebelisoang hape ea elastomer, Ha e bapisoa le OBC le POE, e fokotsa haholo sekhahla sa khatello le sekhahla sa mocheso oa thepa ea foam ea EVA.Lintlha-khōlō tse ling li ntlafalitse elasticity, bonolo, anti-slip le abrasion resistance, ho fokotsa ho apara ha DIN ho tloha ho 580 mm.³ho 179 mm³.

Ntle le moo, Si-TPV e ntlafatsa ho tlala ha 'mala oa thepa ea foam ea EVA.Katleho ena e lumella bahlahisi ho hlahisa lihlahisoa tse khahlang ntle le ho sekisetsa tšebetsong.

Si-TPV ena e le phetoho ea popontshwa bakeng sa foam ea EVA e ruisa molemo tlhahiso ea matšeliso le lihlahisoa tse tšoarellang tsa EVA tse amanang le lekoba joalo ka li-midsoles, lintho tsa bohloeki, lihlahisoa tsa boikhathollo tsa lipapali, mekato, mete ea yoga, le tse ling.
