EVAyenziwe kwi-copolymerization ye-ethylene (E) kunye ne-vinyl acetate (VA), ekubhekiselwa kuyo njenge-EVA, kwaye yinto eqhelekileyo ye-midsole. I-EVA luhlobo olutsha lwezinto zokupakisha ezihambelana nokusingqongileyo. Yenziwe nge-EVA foam, eyoyisa iziphene zerabha yogwebu eqhelekileyo enje nge-brittleness, deformation, kunye nokuchacha kakuhle. Ineenzuzo ezininzi ezifana namanzi kunye nobungqina bokufuma, i-shockproof, ukugquma isandi, ukugcinwa kobushushu, iplastiki elungileyo, ukuqina okuqinileyo, ukuhlaziya, ukukhuselwa kokusingqongileyo, ukuchasana nempembelelo, ukuchasana nokutyibilika kunye nokuxhathisa ukothuka, njl. imathiriyeli yokupakisha yemveli efanelekileyo. ezinye iindlela. I-EVA ineplastiki eyomeleleyo kakhulu. Inokufa-isikwe kuyo nayiphi na imilo, kwaye ingenziwa ngokwezifiso ngokwemizobo yabathengi. Isikhwama sokugcina se-EVA sinokwenziwa ngokwezifiso ngombala, ilaphu kunye nelinen efunwa ngumthengi. I-EVA isetyenziswa ngokubanzi kwi-shockproof, anti-slip, ukutywinwa kunye nokugcinwa kobushushu bezinto zombane, ukufakwa kweebhokisi zokupakisha ezahlukeneyo, iinkonkxa zetsimbi kunye namanye amashishini. Imisebenzi njengokhuselo, i-anti-static, i-fireproof, i-shockproof, ukugcinwa kobushushu, i-anti-slip, kunye ne-fixed. Ukunganxibi kunye nokumelana nobushushu. I-Insulation kunye neminye imisebenzi.
Igama lezenzululwazi le-EPE yipolyethylene eyongezelekayo, ekwabizwa ngokuba yiperile yomqhaphu. Luhlobo olutsha lwezinto zokupakisha ezinokunciphisa kwaye zifunxe ukungcangcazela. Yimveliso ye-polyethylene ene-foam ephezulu ekhutshwe kwi-polyethylene ephantsi (LDPE) njengeyona nto iphambili. Umqhaphu we-EPE weperile unegwebu kwiimilo ezikhethekileyo usebenzisa i-butane, eyenza i-EPE i-elastic ephezulu, iqine kodwa ingabi brittle, kunye nomphezulu othambileyo. Inokuthi ithintele ngokufanelekileyo umonakalo owenziwe kukungqubana ngexesha lokupakishwa kwemveliso kwaye ineempawu ezibalaseleyo zokufunxa nokothuka. . Ngoku isetyenziswa ngokubanzi kwipakethe yezixhobo zombane, ifenitshala, izixhobo zombane ezichanekileyo kunye nezinye iimveliso. Umqhaphu we-pearl we-EPE womelele ngokuchasene ne-oyile yomatshini, igrisi, njl.njl. Ngenxa yokuba ingumzimba weqamza, iphantse ingabinawo amanzi. Ingamelana neoyile, ingqine ukufuma, ingqina ukothuka, ukugquma isandi kunye nokugquma ubushushu, kwaye inokumelana nokukhukuliseka kweekhompawundi ezininzi. Umqhaphu we-pearl we-EPE unokuhlangabezana neemfuno zokupakisha ezahlukeneyo, i-antistatic, i-flame retardant, njl njl ngokweemfuno zeemveliso ezahlukeneyo. Kwakhona inemibala ecebileyo kwaye kulula ukuyiqhuba.
Igama lenzululwazi lesiponji yirabha ethambileyo yogwebu ye-polyurethane, enokusetyenziswa ngokucacileyo ekufunxeni ukothuka, ukuchasana nokukhuhlana, kunye nokucoca. Iindidi zohlulwe zibe siponji sepolyester kunye nesiponji sepolyether, eziphinde zohlulwe zibe ziindidi ezintathu: i-rebound ephezulu, i-medium rebound kunye ne-slow rebound. I-sponge ithambile kwi-texture, ikwazi ukumelana nobushushu (inokumelana nokushisa kwama-degrees angama-200), kwaye kulula ukutshisa (i-flame retardants inokongezwa). Ngokuxhomekeke kubungakanani bamaqamza angaphakathi, inokubonisa ingxinano eyahlukahlukeneyo kwaye inokubunjwa ngokwemilo eyahlukeneyo njengoko kufuneka. Inoluhlu olubanzi lokusetyenziswa kwaye lusetyenziswa ikakhulu kwi-shockproof, i-thermal insulation, ukuzaliswa kwezinto, amathoyizi abantwana, njl.
Umahluko omkhulu phakathi kwezi zintathu zezi zilandelayo:
1. Siyawubona umahluko phakathi kwabo ngamehlo ethu eze. Isiponji sikhaphukhaphu kwezi zintathu. Ityheli kancinane kwaye ilastiki. U-EVA ngoyena unzima phakathi kwabathathu. Imnyama kwaye ilukhuni noko. Umqhaphu we-pearl we-EPE ubonakala umhlophe, ekulula ukwahlula kwisipontshi. Isiponji siya kubuyela ngokuzenzekelayo kwimilo yaso yoqobo nokuba uyicinezela njani, kodwa umqhaphu we-EPE weperile uya kuboboka kwaye wenze isandi esiphumayo xa usicinezela.
2. Uyakwazi ukubona iipateni ze-wavy kwi-EPE pearl cotton, njenge-foam eninzi ehlanganiswe kunye, ngelixa i-EVA inemilo kwaye inokwahlula ngokugxininiswa kwayo.
