Iriburiro: Guhuza imiterere ya firime ya firime irakomeye cyane.Irashobora gushushanywa kuri plastiki, ibyuma, ikirahure nibindi bikoresho bipakira.Shrink ya firime yerekana ibirango biramenyekana cyane kumasoko kuko irashobora guhuza imiterere yo murwego rwohejuru hamwe nuburyo butandukanye.Iyi ngingo isangiye ubumenyi bujyanye no kugabanya amafilime yerekana ibicuruzwa, ibikubiyemo ni ibyerekeranye ninshuti:
Kugabanya ikirango cya firime
Shrink ya firime amaboko ni label ya firime yanditswe kuri firime ya plastike cyangwa umuyoboro wa plastiki.
01 Ibiranga
1) Kugabanya amafirime ya firime yerekana ibirango biroroshye, gufunga ibicuruzwa, gukumira umwanda, kurinda neza ibicuruzwa;
2) Igifuniko cya firime cyegereye ibicuruzwa, ibipfunyika biroroshye, kandi birashobora kwerekana imiterere yibicuruzwa, bityo birakwiriye kubicuruzwa bidasanzwe bigoye kubipakira;
3) Kugabanya firime yerekana ikirango cyanditseho, udakoresheje ibifatika, kandi birashobora kubona umucyo nkikirahure;

Igishushanyo mbonera
Igishushanyo mbonera cyerekana imitako ku gipfukisho cya firime kigomba kugenwa ukurikije ubunini bwa firime.Mugihe dushushanya igishushanyo, dukwiye kubanza gusobanura neza igipimo cyo kugabanuka gutambitse kandi birebire bya firime, kimwe nigipimo cyemewe cyo kugabanuka kwa buri cyerekezo nyuma yo gupakira hamwe nikosa ryemewe rya deformasiyo yuburyo bwo gushushanya nyuma yo kugabanuka, kugirango tumenye neza ko igishushanyo ninyandiko nyuma yo kugabanuka birashobora kugarurwa neza.
Ubunini bwa firime no kugabanuka
Ibikoresho bikoreshwa mukugabanya ibirango bya firime bigomba kwibanda kubintu bitatu: ibisabwa kubidukikije, ubunini bwa firime no kugabanuka.
Ubunini bwa firime bugenwa hashingiwe kumurima washyizweho wa label hamwe nikiguzi.Birumvikana ko igiciro atari cyo kintu gifatika, kuko buri firime irihariye, kandi uyikoresha nu icapiro ryikirango agomba kumenya firime hamwe nibikorwa bikwiranye neza nibikoresho mbere yo gusinya amasezerano.Byongeye kandi, ibikoresho byo gutunganya bisabwa ibipimo nibindi bintu bikora nabyo bigira ingaruka muburyo bwo guhitamo ubunini.Ubunini bwa firime yubunini bwa firime ishobora kugabanuka ni 30-70 mm, muribo, film ya 40μm na 50μm ikoreshwa cyane.Byongeye kandi, igipimo cyo kugabanuka kwa firime kirakenewe, kandi igipimo cyo kugabanuka kwa transvers (TD) kiri hejuru yikigereranyo cyo kugabanuka (MD).Igabanuka ryo kugabanuka ryibikoresho bisanzwe ni 50% ~ 52% na 60% ~ 62%, kandi birashobora kugera kuri 90% mubihe bidasanzwe.Igipimo kirekire cyo kugabanuka kigomba kuba 6% ~ 8%.Mugihe ukora firime ya shrike ibirango, gerageza uhitemo ibikoresho hamwe no kugabanuka kurekure.
Ibikoresho bya firime
Ibikoresho byingenzi byo gukora ibirango bya firime bigabanya ni firime ya PVC, film ya PET, film ya PETG, film ya OPS, nibindi. Imikorere yayo niyi ikurikira:
1) Indwara ya PVC
PVC firime nimwe mubikoresho bya firime bikoreshwa cyane.Igiciro cyacyo ni gito, igipimo cyo kugabanuka kwubushyuhe ni kinini, icyifuzo cyinkomoko yubushyuhe ntabwo kiri hejuru, isoko nyamukuru itunganya ubushyuhe ni umwuka ushyushye, infragre cyangwa guhuza byombi.Ariko PVC iragoye kuyitunganya, mugihe yatwitse gaze yuburozi, ntabwo ari byiza kurengera ibidukikije, muburayi, Ubuyapani bwabujije ikoreshwa.
2) firime ya OPS
Nubundi buryo bwa firime ya PVC, film ya OPS yakoreshejwe cyane.Ifite imikorere myiza yo kugabanuka kandi ni nziza kubidukikije.Isoko ryimbere muri iki gicuruzwa rirahagije, kandi kuri ubu OPS yo mu rwego rwo hejuru iterwa ahanini n’ibitumizwa mu mahanga, bikaba byarabaye ikintu gikomeye kibuza iterambere ryacyo.
3) Filime ya PETG
PETG copolymer firime ntabwo ifasha gusa kurengera ibidukikije, kandi irashobora kugabanywa mbere yo kugabanuka.Ariko, kubera ko igipimo cyo kugabanuka ari kinini, bizagarukira kubikoresha.
4) PET firime
PET firime ni mpuzamahanga izwi kubidukikije byangiza ibidukikije ubushyuhe bugabanuka.Ibipimo bya tekiniki, imiterere yumubiri, urutonde rwimikoreshereze nuburyo bukoreshwa byegereye firime ya PVC yubushyuhe bwo kugabanya ubushyuhe, ariko igiciro gihendutse kuruta PETG, ni firime yateye imbere idafite icyerekezo.Igabanuka ryacyo rya horizontal rigera kuri 70%, igipimo cyo kugabanuka kwigihe kirekire kiri munsi ya 3%, kandi ntabwo ari uburozi, nta mwanda, nicyo kintu cyiza cyo gusimbuza PVC.
Mubyongeyeho, ubushyuhe bugabanuka bwa firime ya firime nayo ni umusaruro wibikoresho bya firime bigabanuka, kandi mubikorwa bishobora gukorwa nta kudoda.Ugereranije na horizontal ya firime iringaniye, ikiguzi cyo gukora firime ya firime yamashanyarazi yagabanutse hamwe nubushyuhe bwa firime ya firime iragabanuka, ariko gucapa hejuru yumubiri wigituba biragoye kubigeraho.Muri icyo gihe, amashusho n'amashusho byerekana ubushyuhe bwa firime ya label irashobora kugabanuka gusa hejuru ya firime, byoroshye kwambara mugihe cyo gutwara no kubika, bityo bikagira ingaruka kubipfunyika.
03 ibicuruzwa byarangiye
Gucapa
Shira kuri firime yatoranijwe.Kugeza ubu, gucapura firime bigabanya cyane cyane icapiro rya intaglio, ukoresheje wino ishingiye kuri solvent, ikurikirwa no gucapa flexographic.Hamwe niterambere rya tekinoroji ya flexo yo gucapa, amabara yo gucapa arasa kandi arasobanutse, ugereranije no gucapa gravure, hamwe nubunini bwimbitse nuburebure bwa gravure.Byongeye kandi, icapiro rya flexo ukoresheje wino ishingiye kumazi, bifasha cyane kurengera ibidukikije.
Gukata
Hamwe nimashini ikora cyane, ibikoresho bya firime byacapwe byacishijwemo uburebure, kandi igice cyuruhande rwa firime kiravurwa kugirango gikorwe neza, kiringaniye kandi nticyoroshye.Mugihe ukoresheje scutters, hagomba kwitonderwa kugirango wirinde icyuma gishyushye, kuko icyuma gishyushye kizatuma firime igabanywa igice cyiminkanyari.
Kudoda
Filime yacagaguritse yashushanyije hagati hamwe na mashini yo kudoda, kandi umunwa wigituba wahambirwaga kugirango ukore amaboko ya firime akenewe mu gupakira.Amafaranga yibikoresho asabwa mugushushanya biterwa nukuri kwa suture nubuhanga bwumukoresha.Amafaranga ntarengwa yo kudoda ni 10mm, mubisanzwe 6mm.
Gukata
Amaboko ya firime yapakiwe hanze yibicuruzwa hanyuma agabanywa mu buryo butambitse ukurikije ubunini bw'ipaki hamwe na scutter.Shrinkage firime mubushyuhe bukwiye, uburebure bwayo nubugari bizagira kugabanuka gukabije (15% ~ 60%).Mubisanzwe birasabwa ko ubunini bwa firime buba hafi 10% kurenza ubunini ntarengwa bwibicuruzwa.
Ubushyuhe buragabanuka
Shyushya unyuze mu bice bishyushye, ifuru ishyushye cyangwa imbunda ishyushye.Muri iki gihe, ikirango cyo kugabanuka kizahita kigabanuka kumurongo winyuma wikintu, kandi urucacagu rwinyuma rwikintu rufatanije cyane, rukora ikirango kirinda urwego rwose ruhuza imiterere yikintu.
Mubikorwa byo gutunganya ibirango bya firime bigabanuka, gutahura neza buri gikorwa bigomba gukorwa nimashini idasanzwe yo kumenya kugirango umusaruro ube mwiza.
04 Igipimo cyo gusaba
Guhuza n'imihindagurikire ya label irakomeye cyane, irashobora gukoreshwa mugushushanya hejuru no gushushanya ibiti, impapuro, ibyuma, ikirahure, ceramic nibindi bikoresho bipakira.Ikoreshwa cyane mu gupakira no gushushanya ibiryo, ibikomoka ku miti ya buri munsi n’ibicuruzwa bivura imiti, nkubwoko bwose bwibinyobwa, amavuta yo kwisiga, ibiryo byabana, ikawa nibindi.Mu rwego rwibiyobyabwenge, impapuro ziracyari substrate nyamukuru, ariko iterambere ryapakira firime ryihuse cyane.Kugeza ubu, urufunguzo rwo guteza imbere kugabanuka kwa firime ya label ni ukugabanya ibiciro, gusa murubu buryo burashobora kuzamura irushanwa no guharanira umugabane munini ku isoko.
