Hamwe nogukomeza kuzamura imibereho, ubuzima bukomeye bwabantu ntibugarukira kubiryo ubwabyo. Ibisabwa mubipfunyika nabyo biriyongera. Gupakira ibiryo byahindutse igice cyibicuruzwa bivuye mubufasha bwacyo. Ni ngombwa kurinda ibicuruzwa, Ni ngombwa cyane koroshya kubika no gutwara, guteza imbere kugurisha, no kongera agaciro k'ibicuruzwa.
Gucapa ibiryo byoroshye ibikoresho byo gupakira
Uburyo bwo gucapaIcapiro ryibiryo byoroshyeishingiye cyane cyane ku icapiro rya gravure na flexografiya, hagakurikiraho imashini zicapura za flexografiya zo gucapa firime ya pulasitike (imashini zandika za flexografiya ahanini zikora imirongo ikora hamwe n’imashini zumye), ariko hamwe no gusohora, ugereranije n’icapiro rusange rya gravure hamwe n’icapiro rya flexografiya rikoreshwa mu gucapa ibicuruzwa, hari byinshi bitandukanye. Kurugero: Icapiro ryoroshye ryacapwe ryacapwe hejuru yumuzingo umeze nkumuzingo. Niba ari firime ibonerana, igishushanyo gishobora kugaragara inyuma. Rimwe na rimwe, birakenewe kongeramo irangi ryera cyangwa gukoresha uburyo bwo gucapa imbere.
② Ibisobanuro byuburyo bwo gucapa inyuma Gusohora inyuma bivuga uburyo bwihariye bwo gucapa bukoresha isahani yo gucapa ifite ishusho ihindagurika hamwe ninyandiko kugirango wohereze wino imbere mubikoresho byacapwe bisobanutse, kugirango ishusho nziza ninyandiko bishobora kugaragara imbere Bya Byacapwe.
Ibyiza bya Liyin
Ugereranije no gucapa hejuru, gutondekanya ibintu bifite ibyiza byo kuba byiza kandi byiza, amabara / adashira, bitagira ubushyuhe kandi birinda kwambara. Nyuma yo gucapa umurongo wongeyeho, urwego rwa wino rushyizwe hagati yibice bibiri bya firime, bitazanduza ibintu byapakiwe.
Guteranya ibiryo byoroshye ibikoresho byo gupakira
Method Uburyo bwo kuvanga amazi: Kwambika igipande cyumuti ushonga amazi hejuru yibikoresho fatizo (firime ya plastike, fayili ya aluminiyumu), ukabishyira hamwe nibindi bikoresho (impapuro, selile) ukoresheje akayunguruzo, hanyuma ukumisha mubishyushye kumisha tunnel Hinduka icyarimwe. Ubu buryo burakwiriye gupakira ibiryo byumye.
Method Uburyo bwumye bwa lamination: banza ushyireho ibishingwe bishingiye kumashanyarazi bingana kuri substrate, hanyuma ubyohereze kumuyoboro ushyushye wumye kugirango uhumeke neza, hanyuma uhite uhinduranya ikindi gice cya firime. Kurugero, firime ya polypropilene yerekanwe (OPP) muri rusange yunganirwa nibindi bikoresho ukoresheje inzira yumye nyuma yo gucapa imbere. Imiterere isanzwe ni: firime ya polypropilene yerekanwe (BOPP, 12 mkm), aluminium foil (AIU, 9 mm) hamwe na firime ya polipropilene idafite icyerekezo (CPP, 70 μ m). Inzira nugukoresha igikoresho cyo gutwikisha uruzitiro kugirango rushyire hamwe "ifu yumye yumye" ishingiye ku bikoresho fatizo, hanyuma ubyohereze kumuyoboro ushyushye wumye kugirango uhumeke neza mbere yo kuyishiramo ikindi gice cya firime ukoresheje a uruziga.
Method Uburyo bwo kuvanga ibicuruzwa biva mu mwenda usohora umwenda umeze nka polyethylene ushongeshejwe uva mu gipande cya T, ukawukandagira ukoresheje uruziga, hanyuma ukawujugunya ku mpapuro cyangwa firime kugira ngo ushire polyethylene, cyangwa ugatanga izindi filime zo mu gice cya kabiri cyo kugaburira impapuro. Koresha polyethylene nkigikoresho gifatika kugirango uhuze.
Method Uburyo bushyushye bwo gushonga: Polyethylene-acrylate copolymer, acide Ethylene-Ethylene copolymer, hamwe n’ibishashara bya paraffin birashyuha kandi bigashonga hamwe, hanyuma bigashyirwa kuri substrate, bigahita byongerwaho nibindi bikoresho hanyuma bigakonja.
⑤Multi-layer extrusion compounding method
Amashanyarazi atandukanye ya plastike afite ibintu bitandukanye anyuzwa muri extruders nyinshi hanyuma akajyanwa mubibumbano kugirango akore firime. Iyi nzira ntisaba ibifunga cyangwa ibishishwa kama hagati yurwego, kandi firime ntigira umunuko cyangwa kwangirika kwangirika, bigatuma iba ibipfunyika byibiribwa hamwe nubuzima buramba. Kurugero, imiterere rusange ya LLDPE / PP / LLDPE ifite umucyo mwiza kandi ubunini muri rusange ni 50-60 mm. Niba ifite igihe kirekire. Harasabwa ibice birenga bitanu bya firime-barrière-hamwe-hamwe na firime yo hagati ikozwe mubikoresho byo hejuru cyane PA, PET na EVOH.
