Munzanga yemazuva ano, magirazi haasi chete chigadziro chekugadzirisa maonero, asiwo chiratidziro chefashoni uye unhu. Sezvo kuwanda kwemagirazi kushandiswa kunowedzera, zvinonyanya kukosha kuchengetedza magirazi kubva mukukuvadzwa. EVA magirazi makesi ave sarudzo yekutanga kune vanoda magirazi nekudzivirira kwavo kwakanaka uye kutakura. Ichi chinyorwa chichatarisa zvakadzama kuti seiEVA magirazimakesi anodzivirira magirazi uye kukosha kwayo muhupenyu hwemazuva ano.
Nhanganyaya kune EVA zvinhu
EVA, kana ethylene-vinyl acetate copolymer, chinhu chakareruka, chakapfava uye chakanyanya elastic. Iyo ine yakanaka cushioning zvimiro, makemikari corrosion kuramba uye kuchembera kuramba, izvo zvinoita EVA chinhu chakanakira kugadzira magirazi makesi.
1.1 Cushioning zvivakwa
Iyo cushioning zvimiro zveEVA zvinhu zvinonyanya kukonzerwa nevinyl acetate yemukati mune yayo molecular chimiro. Iyo yakakwira iyo vinyl acetate yemukati, zvirinani kupfava uye elasticity yeEva, ichipa zvirinani kubatwa.
1.2 Chemical resistance
EVA ine kumira kwakanaka kumakemikari mazhinji, zvinoreva kuti inogona kudzivirira magirazi kubva mukukukurwa kwemakemikari anogona kusangana muhupenyu hwezuva nezuva.
1.3 Anti-kuchembera
EVA zvinhu hazvisi nyore kukwegura uye inogona kuchengetedza kushanda kwayo kunyange mushure mekushandisa kwenguva refu, iyo inopa kuchengetedzwa kwenguva refu kwemagirazi.
Dhizaini yeEVA magirazi kesi
Dhizaini yeEVA magirazi kesi inonyatso funga nezve kuchengetedza zvinodiwa zvemagirazi. Kubva pachimiro kusvika kune chimiro chemukati, zvese zvinotaridza kutarisirwa kwemagirazi.
2.1 Chimiro dhizaini
EVA magirazi kesi inowanzogadzirwa kuti ienderane nechimiro chemagirazi, ayo anogona kuve nechokwadi chekuti magirazi haazununguke muchiitiko uye kuderedza kukuvadzwa kunokonzerwa nekukwenya kana kukanganisa.
2.2 Chimiro chemukati
Iyo yemukati dhizaini dhizaini inowanzo sanganisira yakapfava linings, iyo inogona kunge iri jira, chipanje kana zvinyoro zvinhu zvakare zvakagadzirwa neEVA, izvo zvinogona kupa yakawedzera cushioning kuchengetedza kwemagirazi.
2.3 Kushanda kwemvura
Mazhinji magirazi eEVA magirazi haanawo mvura, ayo asingango chengetedza magirazi kubva kune unyoro, asiwo anoita magirazi magirazi akakodzera kushandiswa munzvimbo dzakasiyana siyana.
Dziviriro nzira yeEva magirazi kesi
EVA magirazi kesi inodzivirira magirazi munzira dzakawanda, kubva pakuchengetedzwa kwemuviri kusvika kuchinjika kwezvakatipoteredza, kuve nechokwadi chekuchengetedzwa kwemagirazi mumativi ese.
3.1 Kudzivirirwa kwemuviri
Impact kuramba: EVA zvinhu zvinogona kutora uye kuparadzira simba rekuita, kuderedza kukuvadzwa kwakananga kumagirazi.
Scratch resistance: Iyo yakapfava yemukati inogona kudzivirira kupokana pakati pemagirazi uye magirazi makesi, kudzivirira kukwenya pamalenzi nemafuremu.
Compression resistance: EVA magirazi makesi anogona kumira nehumwe huwandu hwekumanikidza kuchengetedza magirazi kubva pakupwanyika.
3.2 Kuchinja kwezvakatipoteredza
Tembiricha inochinjika: EVA zvinhu zvine yakanaka kuchinjika kune tembiricha shanduko, kungave kuri kupisa zhizha kana kutonhora kwechando, vanogona kuchengetedza yavo yekudzivirira.
Humidity control: Mamwe magirazi eEVA makesi akagadzirwa aine maburi ekufema kuti abatsire kudzora hunyoro hwemukati uye kudzivirira magirazi kubva pakukuvadzwa nekunyorova kwakanyanyisa.
3.3 Kutakurika
EVA magirazi makesi akareruka uye ari nyore kutakura, achibvumira magirazi kuchengetedzwa chero nguva, kungave kumba, muhofisi kana kuenda.
Kugadziriswa uye kuchenesa kweEVA magirazi makesi
Kuti uve nechokwadi chekushanda kwenguva refu kweEVA magirazi makesi, kuchengetedza kwakakodzera uye kuchenesa kwakakosha.
4.1 Kuchenesa
Kugara uchichenesa: Shandisa jira rakapfava kupukuta zvinyoro-nyoro mukati nekunze kwekesi yemagirazi kuti ubvise huruva uye mavara.
Regedza kushandisa makemikari ekuchenesa: Kemikari yekuchenesa inogona kukuvadza iyo EVA zvinhu uye kukanganisa yayo inodzivirira.
4.2 Kuchengeta
Dzivisa kuratidzwa kwenguva refu kuchiedza chezuva: Kugara kwenguva refu kuchiedza chezuva kunogona kukonzera EVA zvinhu kuchembera.
Chengetedza munzvimbo inotonhorera uye yakaoma: Dzivisa tembiricha yepamusoro uye hunyoro kuti uwedzere hupenyu hwesevhisi yekesi yemagirazi.
Mhedziso
Iyo EVA magirazi kesi yave sarudzo yakanaka yekudzivirira magirazi nekuita kwayo kwakanakisa kwekudzivirira, kusimba uye kutakura. Iyo haingodziviriri magirazi kubva mukukuvadzwa kwemuviri, asiwo inogadzirisa kune akasiyana mamiriro ezvakatipoteredza kuti ave nechokwadi chekushandiswa kwenguva refu kwemagirazi. Nekufambira mberi kwetekinoroji uye kuvandudzwa kwesainzi yezvinhu, tinogona kutarisira kuti magirazi eEVA makesi achapa kuchengetedzwa kwakawanda uye kwakanaka mune ramangwana.
