Ubuhanga butandukanye bitewe nuburyo budasanzwe nuburyo bwo gukora buri kintu

Inganda zipakira zishingiye cyane kuburyo bwo gucapa kugirango zishushanye kandi zicupa amacupa n'ibikoresho.Ariko, gucapa kumirahuri na plastike bisaba tekiniki zitandukanye cyane kubera imiterere yihariye nuburyo bwo gukora buri kintu.

Gucapa kumacupa yikirahure

Amacupa yikirahure akorwa cyane cyane hakoreshejwe uburyo bwo kubumba, ahoikirahure gishongeshejwe kirahuha hanyuma kigashyirwa mubibumbano kugirango bibe imiterere yabyo. Ubu bushyuhe bwo hejuru butuma ecran icapa uburyo busanzwe bwo gushushanya ibirahure.

Icapiro rya ecran rikoresha meshi nziza ya ecran irimo igishushanyo mbonera gishyirwa kumacupa yikirahure. Ink irahita inyuzwa ahantu hafunguye ecran, ikohereza ishusho hejuru yikirahure. Ibi bikora firime ya wino yumye yumye vuba mubushyuhe bwinshi. Icapiro rya ecran ryemerera kubyara amashusho meza cyane kumirahuri hamwe na wino ihuza neza hamwe nubuso bworoshye.

Gutunganya icupa ryikirahure akenshi bibaho mugihe amacupa akiri ashyushye kuva umusaruro, bigatuma wino ishobora guhita ikira vuba. Ibi byitwa "kashe ishyushye". Amacupa yacapwe agaburirwa mu ziko rya annealing kugirango akonje buhoro buhoro kandi birinde gucika kumuriro.

Ubundi buryo bwo gucapa ibirahuri birimoitanura ryaka ibirahuri hamwe na UV ikize ibirahureg. Hamwe no gucana, inkera ya ceramic frit iracapwa cyangwa igashyirwa mubikorwa nka decal mbere yuko amacupa agaburirwa mumatara yubushyuhe bwinshi. Ubushyuhe bukabije bushyira ibirahuri by'ibirahure burundu hejuru. Kuri UV-gukiza, wino yunvikana UV iracapwa hanyuma igahita ikira munsi yumucyo mwinshi ultraviolet.

Gucapa kumacupa ya plastike

Bitandukanye n'ikirahure,Amacupa ya pulasitike akorwa no gukuramo ibishishwa, gutera inshinge, cyangwa kurambura ibicu ku bushyuhe buke. Nkigisubizo, plastiki zifite ibisabwa bitandukanye muburyo bwo gufata wino hamwe nuburyo bwo gukiza.

Icapiro rya Flexographic rikoreshwa mugushushanya amacupa ya plastike.Ubu buryo bukoresha ishusho yazamuye ku isahani yoroheje ya fotopolymer izunguruka kandi ikorana na substrate. Irangi ryamazi rifatwa nisahani, ryimurirwa hejuru y icupa, hanyuma rihita rikira nurumuri rwa UV cyangwa urumuri.

Icapiro rya flexografiya ryiza cyane mugucapisha hejuru yuhetamye, yuzuye hejuru yamacupa ya plastike nibikoresho.Amasahani yoroheje yemerera kohereza amashusho kubikoresho nka polyethylene terephthalate (PET), polypropilene (PP), na polyethylene yuzuye (HDPE). Inkingi ya Flexographic ihuza neza na plastike idafite plastike.

Ubundi buryo bwo gucapa plastike burimo gucapa rotogravure hamwe no gushiraho ibimenyetso.Rotogravure ikoresha silinderi yicyuma kugirango yimure wino kubikoresho. Ikora neza kumacupa ya plastike yuzuye. Ibirango bitanga byinshi muburyo bwo gushushanya ibikoresho bya plastiki, byemerera ibishushanyo birambuye, imiterere, n'ingaruka zidasanzwe.

Guhitamo hagati yikirahure nu gupakira plastike bifite uruhare runini muburyo bwo gucapa. Hamwe n'ubumenyi bwa buri kintu hamwe nuburyo bwo gukora, abatunganya amacupa barashobora gukoresha uburyo bwiza bwo gucapa kugirango bagere ku bishushanyo biramba, binogeye ijisho.

Gukomeza guhanga udushya mubirahuri na plastike hamwe niterambere mu buhanga bwo gucapa bizarushaho kwagura uburyo bwo gupakira.
