Ukuba umxhasi wakho ungumntu othanda iimbaleki, akunakubakho mathiriyeli ingcono kune-EVA enika umdla osisiseko wolona luhlu lubanzi lwabalandeli.
Xa uhambisa izinto ukusuka kwenye indawo ukuya kwenye, ilahleko ukusuka kwi-jostling kunye nempembelelo ayinakuthintelwa.Nangona kunjalo, ungasinciphisa esi siphumo ngokusebenzisa amagwebu e-EVA akhuselwe kakhulu kwaye uzise le propati kwi-assortment yakho ye-staples, iimathi ze-yoga, iiteki, iipads zokukhusela, "izixhobo ezixhobileyo", isigcina-ntloko......
EVA, phila ubomi obulungileyo, khusela ubomi ngokukhuselekileyo.
I-EVA, i-ethylene-vinyl acetate, eyaziwa ngokuba yi-poly (i-ethylene-vinyl acetate, i-PEVA), i-copolymer ye-ethylene kunye ne-vinyl acetate.Ngokumalunga nokuguquguquka, ikufutshane ne-elastomer, ke yaziwa njengerabha eyandisiweyo, igwebu le-EVA, kunye nerabha enogwebu.Inokucutshungulwa njenge-thermoplastics, enamanqanaba aphezulu ekhemikhali yokuphambanisa, okukhokelela kwiimveliso zeeseli ezivaliweyo ezinobumbano obucolekileyo, obufanayo.
Ipesenti yobunzima be-vinyl acetate ngokuqhelekileyo iyahluka phakathi kwe-18% kunye ne-40%, kunye nentsalela yi-ethylene.Ngokuxhomekeke kwizithako kwinkqubo yokuvelisa, amanqanaba ahlukeneyo obunzima be-EVA inokufumaneka.Kubalulekile ukuqwalasela inqanaba lobulukhuni njengoko i-EVA ingabuyi kubume bayo emva koxinzelelo oluqhubekayo.Xa kuthelekiswa ne-EVA enzima, i-EVA ethambileyo inoxhathiso oluncinci lwe-abrasion kunye nobomi obufutshane be-outsole, kodwa intuthuzelo ephezulu.
Igwebu le-EVA linoluhlu olubanzi lweepropathi ezilungileyo:
Ukumelana nokufuma (ukufunxwa kolwelo okuphantsi)
ukugxotha imichiza
Ukufunxa isandi kunye nokugquma isandi
Ukungcangcazela kunye nokufunxa ukothuka (ukuxhathisa ukuqhekeka koxinzelelo)
Ukuguquguquka koyilo
Ukumelana nemozulu (ubushushu obuphantsi, ukuxhathisa kwimitha ye-UV)
ukugquma ubushushu, ukumelana nobushushu
isithinteli
ukudambisa
Amandla aphezulu kumlinganiselo wobunzima
ubuso obugudileyo
Iplastiki, i-ductility, i-thermoplasticity, njl.
|Ifomula yokuvelisa i-EVA
Inkqubo yokuvelisa izinto ze-foam ze-EVA ziquka i-pelletizing, ukudibanisa kunye nokukhupha amagwebu.I-resin ye-EVA icutshungulwa ibe ngamancinci amancinci ngokwaneleyo, kwaye ke ngokomlinganiselo othile, ezi ngqungquthela zixutywe kunye nezinye izongezo kunye neentlobo ezahlukeneyo zokuvelisa izinto ezahlukeneyo ze-foam ze-EVA. Njengezinto eziphathekayo ze-EVA foam, izinto eziphambili ziyi-EVA, i-filler, i-foam. i-agent, i-agent ye-bridging, i-accelerator ekhupha ugwebu, i-lubricant;izixhobo ezincedisayo arhente antistatic, idangatye retardant, arhente yokunyanga ngokukhawuleza, umbala, njalo njalo. Umxube ekhethiweyo amagwebu kunye catalyst umxube imisela ingxinano, ubulukhuni, umbala kunye neempawu ukomelela.Abavelisi ngoku baphuhlisa i-ultralight, conductive, antistatic, shock resistant, antibacterial, fireproof and biodegradable formulations ngeenjongo ezizodwa.
Umatshini wokusika ucingo olushushu lwe-Eva
