Firimu reEVAimhando yechinamatidzo chinonyunguduka, chiri copolymer ye ethylene vinyl acetate. Chinogadzirwa kuburikidza netekinoroji yesainzi uye chinosanganiswa nekukurumidza, purasitiki, extrusion, shaping, cooling, measurement and winding processes. Mushure mekugadzirwa kuita firimu, harina kunamira patembiricha yemukamuri uye rinonyunguduka kuburikidza ne vacuum hot pressing mumidziyo yegirazi laminating. Firimu reEVA rakagadziriswa rine kuchinjika kwakanaka, rinodzivirira kukanganiswa, kujeka kwakanyanya, uye kunamira kwakasimba kwazvo; Uyezve, rinodzivirira zvakanyanya kukanganiswa kwezvakatipoteredza, rinodzivirira hunyoro, rinodzivirira mamiriro ekunze, kuvharwa kwekupisa, nezvimwe zvinhu. Ndiwo chaiwo maitiro aya ane EVA akatungamira mukusimudzirwa nekukurumidza nekushandiswa kwefirimu reEVA mumaindasitiri egirazi negirazi reunyanzvi kubvira 2000. Pakutanga kwekugadzirwa nekushandiswa kwefirimu reEVA, nekuda kwemafomula akasiyana-siyana ehunyanzvi, rakanyanya kunangwa kumabhizinesi ekugadzira girazi rakadzika muminda yezvinhu zvekushongedza zvekuvaka, kusimbisa waya neglue bonding, nezvimwewo, zvichitsiva mhedzisiro yakaipa nezvikanganiso zvinokonzerwa nechinamatidzo chinonamira kwenguva refu. Mhando dzakasiyana dzezvigadzirwa zveEVA mumusika dzatanga kuratidza mafambiro ekusiyana-siyana: kubva pamhando imwe chete yakajairika inopenya kusvika pakuwedzera nekuwedzera kwemavara anopenya, mavara asingaonekwe, uye dhayi redhisiki. Izvi zvinokonzerwa nekugadziriswa kwemusika, uko kunosangana zvakanyanya nezvinodiwa zvemakambani ekugadzira magirazi akadzika ezvigadzirwa zveEVA.
Nezvekuchengetwa kwefirimu
Firimu regirazi rakanamirwa neEVA rinowanzo fanirwa kuchengetwa mudura rinopinda mhepo, rakaoma, uye rakachena, richidzivirira mwaranzi yakananga kubva kuzuva uye panopisa: kudzivirira mvura, kumanikidzwa kwakanyanya, kukanganiswa kwekunze, uye kukwenya kubva pazvinhu zvakaoma; Tembiricha yekuchengetera inofanira kudzorwa pasi pe35 ℃, uye hunyoro hahufanirwe kudarika 60%; Kana paine firimu rakawanda, tireyi inofanira kuiswa pasi pefirimu kuti iite kuti mhepo ipinde, kupisa kuparare, uye kuparadzaniswa kwehunyoro. Kana firimu iri rikasangana nekumanikidzwa, kupisa, kana hunyoro hwakawandisa, richaratidza mwero wakasiyana wekuzvinamira kana kuti kutsvuka pamusoro pefirimu, izvo zvichakanganisa kushandiswa kwakajairika.
Firimu yasara mushure mekushandiswa inofanira kurongwazve nezvinhu zvakachena kudzivirira magetsi asina simba anotakurwa nefirimu pachayo kuti asasvibise guruva uye kusvibisa firimu, zvichikanganisa kushandiswa kwakajairika.
Kuyerera kwakanaka, kazhinji kacho kunobatsira pakugadzirisa zvinhu pa110 ℃. Magirazi ekushongedza ane mapatani nemagadzirirwo anogona kugadzirwa uchishandisa nzira dzakadai sema wire clamps nema roll clamps mu firimu layer. Saka, anonyanya kushandiswa pakuparadzanisa zvinhu mukati meimba nekushongedza.
Firimu repakati reEVA ipolymer yethermoplastic ine kujeka kwakanaka uye inodzivirira kukuvadzwa, inoshandiswa zvakanyanya mukuvaka uye muminda yemotokari. Inodzivirira kutonhora zvakanaka uye inodzivirira kusviba kweUV, izvo zvinogona kudzivirira kukwegura kwegirazi nekudzima.
SemunhuFirimu reEVAMugadziri uye mutengesi akazvipira kuhunyanzvi uye mhando, Fangding Technology Co., Ltd. yagara yakazvipira kupa vatengi mafirimu eEVA anoonekera uye anoshanda zvakanyanya. Kusarudza chigadzirwa chedu zvinoreva kusarudza mhinduro yezvinhu zvemhando yepamusoro inoonekera, yakachengeteka, uye inogara kwenguva refu.
