Mukugadzirisa firimu, imwe mhando yezvinhu zvakasvibirira inokwidziridzwa kune imwe mhando yefirimu yakagadzirwa kana pamhando dzakasiyana dzemafirimu akagadzirwa uye anonamira anoshandiswa kubatanidza pamwechete kugadzira mafirimu akawanda.Ichi chigadzirwa chinonzi composite mafirimu.Co-extruded firimuine maitiro mazhinji emusanganiswa firimu, asi pane imwe mutsauko, ndiko kuti, ese akaturikidzana eiyo co-extruded firimu anowedzeredzwa panguva imwe chete, uye zvidimbu zvinosungirirwa nekunyungudika kunopisa pasina lamination process.
Zvinhu zvemusanganiswa firimu kazhinji epurasitiki, asi bepa, simbi foil (kazhinji aluminium) kana machira anogona zvakare kushandiswa.All layers of theco-extruded filmvari extruded panguva imwe chete, saka hapazovi nealuminium foil, mapepa uye zvimwe zvisiri zvepurasitiki zvinhu.
Multi-layer co-extrusion barrier membrane ifirimu inoshanda inoumbwayakagadzirwa nekushandisa akawanda extruder kuburitsa resin ine yakakwirira chipingamupinyi kuita uye kunyunguduka kwemamwe marezeni kuburikidza nekufa kwakafanana.Multi-layer co-extrusion composite igreen composite kugadzira maitiro, kunyanya kune yazvino indasitiri yekurongedza chikafu, zvigadzirwa zvinoshandiswa zvinowanzo certified neUnited States Food and Health and Safety Agency, uye zvigadzirwa zvinopihwa zvakafanana kune imwe neimwe. chinjika nepombi yekufambisa yakakosha.Iko hakuna kuratidzwa kwezvinhu zvakasvibiswa uye kusvibiswa kwezvakatipoteredza mukugadzirisa.Mutsara waro wekupedzisira wakagadzirwa neLLDPE yakagadziridzwa seyakagadzirwa, iyo isiri-chepfu kune zvakatipoteredza, zvokudya uye muviri wemunhu uye haizooneki tsika yakaoma yakaoma, iyo inonzi, iyo inonzi solvent residue phenomenon, pasina tsvina yakasvibiswa;Izvo zvakasiyanawo nekuoma kusanganisa, kunyungudika-isina kusanganiswa uye general single-layer extrusion compoting process, uye inoda kuomesa ovheni kurapwa, saka mashandisirwo esimba zvakare mashoma.Mukuwedzera, iyo yakawanda-layer co-extrusion composite process inewo zvinotevera zvakanakira.
(1) Yakaderera-inodhura yakawanda-layer co-extrusion composite process inoshandisa akasiyana resin ane mabasa akasiyana.Imwe chete nzira yekuputira kuumba inogona kushandiswa kugadzira akawanda-inoshanda composite zvigadzirwa zvemafirimu, izvo zvinogona kuderedza mutengo wekugadzira.Pamusoro pezvo, inogona zvakare kudzikisa kuita kunodiwa kweresin mbishi zvinhu kusvika paukobvu hudiki, uye hudiki hudiki hweiyo imwe layer hunogona kusvika 2 ~ 3 μ m.Inogona kuderedza zvakanyanya kushandiswa kweresin inodhura, nokudaro kuderedza mari yezvinhu.
(2) Iyo inochinjika yakawanda-layer co-extrusion tekinoroji inogona kuenderana dzakasiyana siyana mbishi musanganiswa wakasiyana uyo unoshandisa zvizere zvigadzirwa zvine zvimiro zvakasiyana uye fomu panguva imwe.Izvo hazvina kuganhurirwa neakakodzera zvigadzirwa zvemusika uye zvinogona kuzadzisa zvinodikanwa zvezviitiko zvakasiyana zvekurongedza.Iyo yakawanda yakaturikidzana, iyo inowedzera kuchinjika dhizaini yekugadzira uye inoderedza mutengo.
(3) High composite performance co-extrusion composite process inosanganisa yakanyungudutswa adhesive uye base resin.Iyi nzira ine yakakwira peel simba iyo inowanzosvika 3N/15mm kana kupfuura iyo yakakodzera kune zvakajairika kurongedza zvinhu.Kune zvigadzirwa zvine yakakwira peel simba zvinodiwa, thermosensitive resin inogona kuwedzerwa kune composite.Zvichakadaro, iyo peel simba inogona kusvika 14N/15mm, kana kutokwira.
(4) Multi-layer co-extruded composite zvigadzirwa zvinogona kuvhara minda yese yekurongedza, kusanganisira chikafu, zvigadzirwa zvemazuva ese zvemakemikari, zvinwiwa, mishonga, mafirimu ekudzivirira uye kunyange zvigadzirwa zvemuchadenga.Parizvino, akawanda akaoma composite zvigadzirwa muChina vakatora co-extrusion process kunze kwenyika.Machubhu emushonga wemazino asingakwanisi kugadzirwa neyakaoma composite process.Pepa epurasitiki aluminium composite zvigadzirwa.Aerospace uye zvimwe zvigadzirwa zvinowanikwawo ne-co-extrusion process.Nekutsvagisa kwakadzama uye kuenderera mberi kwehunyanzvi hwe coextrusion composite resin, tekinoroji uye zvishandiso, akawanda-layer coextrusion composite ichawedzera kusvika kune yakakura siyana.
