PE umufuka ni umufuka usanzwe mubuzima bwacu bwa buri munsi, ukoreshwa muburyo bwose bwo gupakira imbuto n'imboga, imifuka yo guhaha, gupakira ibicuruzwa byubuhinzi, nibindi. Gukora igikapu cya firime isa nkiyoroshye birashobora kuba bigoye cyane.PE ibikapu byo gutunganya ibikapu birimo uduce twa plastike - kuvanga ubushyuhe - kuvanga kurambura - kuvura ibikoresho bya elegitoronike -;Isakoshi ya PE ni inzira nyinshi zavuzwe haruguru, yoroshye nyuma yuburyo butatu: kuvuza firime ------ gucapa ------ gukora imifuka.
PE gucapa ibikapu bigomba kwitondera iki?
Polyethylene, irwanya ubushyuhe buke cyane (koresha ubushyuhe bugera kuri -70 ~ -100), ituze ryimiti, aside nyinshi hamwe nisuri ya alkali (hamwe na okiside ya okiside itihanganirana), idashobora gushonga mumashanyarazi rusange mubushyuhe bwicyumba, kwinjirira gake, gukora neza amashanyarazi.Nyamara, polyethylene yunvikana nibidukikije (ibikorwa bya chimique na mashini) kandi bikennye gusaza.Imiterere ya polyethylene iratandukanye bitewe nubwoko, bitewe ahanini nuburyo bwa molekile nubucucike.Ibicuruzwa bifite ubucucike butandukanye (0.91-0.96 G / CM3) birashobora kuboneka muburyo butandukanye bwo gukora.Polyethylene irashobora gutunganywa nuburyo busanzwe bwo gukora thermoplastique (reba gutunganya plastike).
Ni izihe nyandiko zijyanye n'inzira zirambuye hepfo?
Igikorwa cyo gukina firime kigomba kwitondera ingingo zikurikira:
1. Ikigereranyo cyibikoresho bito: ukurikije ibisabwa bitandukanye byimifuka ya PE, gutegura ibipimo bitandukanye byibikoresho fatizo.Kurugero: anti-static, anti-rust, mituweli, itwara amashanyarazi, biodegradation nibindi bisabwa, ongeraho inyongera zinyongera zingirakamaro kurugero: gukoresha umutuku, umukara, ibara nandi mabara, ongeramo amabara atandukanye.Ukurikije gukorera mu mucyo, gukomera, imbaraga zo kurira, gukuramo vacuum nibindi bisabwa, gusimbuza ibirango bitandukanye cyangwa ibirango byibikoresho bya PE.Kurugero: ukurikije ibisabwa byihariye, shimangira ibisabwa kugirango habeho gukorera mu mucyo, guturika cyane, gufungura neza, kugirango uhindure igipimo cyibikoresho fatizo.
2.uburyo bwo kuvuza firime, gukenera gutunganywa hakoreshejwe ikoranabuhanga, muriki gihe kugirango twite ku mbaraga zo gutunganya ibikoresho bya elegitoroniki, kugirango ingufu za PE ingoma ibikoresho bya elegitoronike bitunganijwe (DAYIN) bihagije kugirango wino ifatanye.
3.mu nzira yo kuvuza firime, ukurikije ibisabwa byihariye bya firime, gufungura rimwe, gufungura kabiri, kuzinga, kwangirika kwingutu, gushushanya, kwaguka nibindi bikorwa.
PE gucapa ibikapu bigomba kwitondera ibibazo bikurikira:
1. gucapa wino: wino ishingiye kumazi, wino yumye byihuse, wino itagaragara, wino ihindura amabara, wino irwanya impimbano, wino yinduction, wino itwara, wino ya elegitoronike nkeya, wino ya matte nibindi biranga wino ni wino.
2. Isahani yo gucapa: ukurikije ibisabwa byiza byo gucapa, gravure (plaque y'umuringa) icapiro hamwe na flexography (offset) ikoreshwa.Ubu buryo bubiri bwo gucapa.
3. Ukurikije ibintu bigoye byo gucapa no kugorana kw'amabara, hitamo uburyo bwo gucapa: icapiro rya monochrome, icapiro rya monochrome impande ebyiri, icapiro ry'uruhande rumwe, gucapa amabara abiri.
4. Ukurikije ibisabwa byihariye byuburyo bwo gucapa, ukurikije ibiranga amabara, kurwanya impimbano, amashanyarazi, amashanyarazi nibindi, hitamo wino cyangwa inyongeramusaruro zitandukanye.
