Kana mutengi wako ari anofarira zvemitambo, panogona kunge pasina zviri nani zvekushongedza zvinhu kupfuura EVA inobata kune zvakakosha zvido zvehuwandu hwakakura hwevateveri.
Kana uchiendesa zvinhu kubva kune imwe nzvimbo uchienda kune imwe, kurasikirwa kubva mukudhumhana uye kukanganisa hazvidzivisike.Nekudaro, iwe unogona kudzikisira mhedzisiro iyi nekushandisa yakanyatso cushion EVA furo uye kuunza ichi chivakwa kune ako emhando dzakasiyana-siyana, yoga mats, sneakers, ekudzivirira pads, "zvombo zvehondo", ngowani......
EVA, rarama zvinoenderana nehupenyu hwakanaka, chengetedza hupenyu zvakachengeteka.
EVA, ethylene-vinyl acetate, inozivikanwawo sepoly (ethylene-vinyl acetate, PEVA), iri copolymer ye ethylene uye vinyl acetate.Panyaya yekuchinjika, iri padyo ne elastomer, saka inowanzo zivikanwa seyakawedzerwa rabha, furo reEVA, uye rabha rine furo.Inogona kugadzirwa senge thermoplastics, ine huwandu hwakanyanya hwemakemikari crosslinking, zvichikonzera semi-yakaomarara yakavharwa-sero zvigadzirwa zvine yakanaka, mayunifomu maseru zvimiro.
Huremu muzana yevinyl acetate inowanzosiyana pakati pe18% ne40%, uye yasara iri ethylene.Zvichienderana nezvinosanganiswa mukuita kwekugadzira, mazinga akasiyana eEVA kuomarara anogona kuwanikwa.Izvo zvakakosha kuti titarise iyo yekuoma nhanho sezvo EVA isingadzore chimiro chayo mushure mekumanikidza kunoramba kuripo.Kana ichienzaniswa neyakaoma EVA, yakapfava EVA ine kushoma abrasion kuramba uye ipfupi outsole hupenyu, asi yakakwirira kunyaradza.
EVA foam ine huwandu hwakawanda hwezvakanaka zvivakwa:
Moisture resistance (kunyura kwemvura shoma)
makemikari ekudzinga
Kutora inzwi uye kuvhara inzwi
Vibration uye kubatwa nekuvhunduka (kunetsekana kutsemuka kuramba)
Dhizaini kuchinjika
Kuramba kwemamiriro ekunze (kusimba kwekushisa kwakadzika, UV radiation kuramba)
kupisa-kudzivirira, kupisa-kupisa
buffer
damping
High simba kune uremu reshiyo
yakatsetseka pamusoro
Plastiki, ductility, thermoplasticity, nezvimwe.
|EVA yekugadzira fomula
Iyo nzira yekugadzira yeEVA furo zvinhu inosanganisira pelletizing, kusanganisa uye kupupa.Iyo EVA resin inogadziriswa kuita zvidimbu zvidiki zvakakwana, uyezve mune imwe chikamu, zvimedu izvi zvinosanganiswa nezvimwe zvinowedzera uye akasiyana magadzirirwo kugadzira akasiyana EVA furo zvinhu. mumiririri, bhiriji mumiririri, furo accelerator, lubricant;ebetsero zvinhu vari antistatic mumiririri, murazvo retardant, kukurumidza kurapa mumiririri, colorant, etc. The akasarudzwa furo chiwedzeredzo uye catalyst musanganiswa anosarudza density, kuoma, ruvara uye kusimba zvinhu.Vagadziri vave kugadzira ultralight, conductive, antistatic, shock resist, antibacterial, fireproof uye biodegradable formulations nekuda kwezvinangwa zvakakosha.
