Isakoshi yo gutekesha irimo ubushyuhe bwinshi ni ikintu cyiza cyane. Dushobora kutabona iyi paki iyo dusanzwe turya. Mu by'ukuri, isakoshi yo gutekesha irimo ubushyuhe bwinshi si isakoshi isanzwe yo gupakira. Irimo umuti wo gushyushya kandi ni ubwoko bw'ibice bivanze. Isakoshi isanzwe yo gupakira, twavuga ko isakoshi yo gutekesha irimo ubushyuhe bwinshi ihuza imiterere y'igikoresho n'isakoshi yo gutekesha. Ibiryo bishobora kuba byose mu isakoshi, nyuma yo gukaraba no gushyushya ku bushyuhe bwinshi (ubusanzwe 120 ~ 135℃), bishobora kuribwa nyuma yo kubikuramo. Nyuma y'imyaka irenga icumi ikoreshwa, byagaragaye ko ari igikoresho cyiza cyo gupakira. Ikwiriye gupakira inyama na soya, byoroshye, bifite isuku kandi ni ingirakamaro, kandi ishobora kugumana uburyohe bw'umwimerere bw'ibiryo, bukundwa n'abaguzi.
Birumvikana ko ipaki ya mbere ishobora kubika ibiryo by'inyama ku bushyuhe bw'icyumba ari ibiryo byo mu macupa, ari byo icupa ry'icyuma rikozwe mu icupa, hanyuma rigakoresha amacupa y'ikirahure nk'ipaki yo hanze. Amacupa yombi ya tinplate n'ay'ikirahure afite ubushobozi bwo guteka mu bushyuhe bwinshi kandi afite ubushobozi bwo kurengera ibidukikije, bityo igihe cyo kubika ibiryo byo mu macupa gishobora kugera ku myaka irenga 2. Ariko, kubera ko amacupa ya tinplate n'amacupa y'ikirahure ari ibikoresho bikomeye byo gupakira bifite ingano nini kandi biremereye, tinplate ifite ubushobozi bwo kudakora ingese, cyane cyane iyo yuzuyemo ibiryo bikomoka kuri aside, iyoni z'ibyuma zihita zigwa byoroshye, ibyo bigira ingaruka ku buryohe bw'ibiryo. Mu myaka ya 1960, Leta Zunze Ubumwe za Amerika zavumbuye filime ya aluminiyumu-plastiki kugira ngo ikemure uburyohe bw'ibiryo byo mu kirere. Ikoreshwa mu gupakira ibiryo by'inyama, kandi ishobora kubikwa ku bushyuhe bw'icyumba binyuze mu gukaraba ubushyuhe bwinshi no mu muvuduko mwinshi, kandi igihe cyo kubika kirenga umwaka 1. Uruhare rwa filime ya aluminiyumu-plastiki ni nk'urw'icupa, ryoroshye kandi ryoroheje, bityo ryitwa "icupa ryoroshye".
Ku bijyanye no gupfunyika ibiryo, imifuka ishyushye cyane ifite byinshi byihariyeinyunguugereranije n'ibikoresho byo gushyiramo ibyuma mu macupa n'imifuka yo gupfunyikamo ibiryo ikonje:
①Komeza ibara,Impumuro, uburyohe n'imiterere y'ibiryo.Agafuka ko gusubiza ibiryo ni gato, kandi gashobora kuzuza ibisabwa mu gihe gito, kandi kagatuma ibara ry’umwimerere, impumuro nziza, uburyohe n’imiterere y’ibiryo bigumana uko bishoboka kose.
byoroshye gukoresha.Umufuka wo gupfumura ushobora gufungurwa byoroshye kandi mu mutekano. Mu gihe urya, shyira ibiryo hamwe n'umufuka mu mazi abira hanyuma ubishyushye iminota 5 kugira ngo ubifungure kandi ubirye, nubwo bitaba bishyushye.
②Ububiko bworoshye no gutwara ibintu.Isakoshi yo gutekeshamo ni nto, ishobora gushyirwa hamwe ikabikwa, kandi ifata umwanya muto. Nyuma yo gupakira ibiryo, umwanya ukoreshwa uba muto ugereranije n'uw'icyuma gipfunyika, gishobora gukoresha neza umwanya wo kubika no gutwara ibintu no kuzigama amafaranga yo kubibika no gutwara ibintu.
kuzigama ingufu.Bitewe n'uko agafuka ko gutekesha gafite ubugari, gashobora kugera ku bushyuhe bwica bwa bagiteri vuba iyo gashyushye, kandi ingufu zikoreshwa zikaba 30-40% munsi y'izakoreshejwe mu icupa rya fer.
③byoroshye kugurisha.Amasashe yo gupfunyika ashobora gupfunyikwa cyangwa guhuzwa n'ibiribwa bitandukanye bitewe n'ibyo isoko rikeneye, kandi abakiriya bashobora guhitamo uko bishakiye. Byongeye kandi, bitewe n'ubwiza bw'isura, ingano y'ibicuruzwa nayo yariyongereye cyane.
④igihe kirekire cyo kubika.Ibiryo bipfunyitse mu mifuka idasaba firigo cyangwa gukonjesha, bifite igihe gihoraho cyo kubikamo nk'amacupa y'icyuma, biroroshye kugurisha, kandi biroroshye kubikoresha mu rugo.
⑤ kugabanya ikiguzi cyo gukora.Igiciro cya filime ivanze yo gukora isakoshi yo gusimbuza kiri hasi ugereranyije n'icyapa cy'icyuma, kandi inzira yo kuyikora n'ibikoresho bikenewe biroroshye cyane, bityo igiciro cya sakoshi yo gusimbuza kiri hasi.
Imiterere y'ibicuruzwa by'amasashe yo gutekeshamo mu bushyuhe bwinshi
Muri rusange bigabanyijemo ibyiciro bitatu: filime y'ibice bibiri, filime y'ibice bitatu n'imiterere ya filime y'ibice bine.
Filimi y'ibice bibiri muri rusange ni BOPA/CPP, PET/CPP;
Imiterere ya filime y'ibice bitatu ni PET/AL/CPP、BOPA/AL/CPP；
Imiterere ya filime y’ibice bine ni PET/BOPA/AL/CPP，PET/AL/BOPA/CPP。
Igenzura ry’ubushyuhe bwinshi mu guteka
Nyuma yo gukora ishashi, shyiramo ingano imwe y'ibirimo mu ishashi hanyuma uyifunge neza (Icyitonderwa: ibirimo bisa n'ibirimo byavuzwe n'umukiriya, kandi ugerageze gusohora umwuka uri mu ishashi mu gihe ufunze, kugira ngo bitagira ingaruka ku ngaruka z'igerageza bitewe no kwaguka k'umwuka mu gihe cyo guteka). Shira mu isafuriya yo gutekesha ifite umuvuduko wo hejuru wa ts-25c, hanyuma ushyireho ibisabwa n'umukiriya (ubushyuhe bwo guteka, igihe, umuvuduko) kugira ngo ugerageze uburyo bwo guteka bushyuhe bwinshi; uburyo bwo gukora ishashi yo guteka ifite ubushyuhe bwinshi ubu ni bwo shashi nziza yo guteka ku isi. Inyinshi muri zo zikorwa hakoreshejwe uburyo bwo guteka bwumye, kandi nke zishobora no gukorwa hakoreshejwe uburyo bwo guteka budafite solvent cyangwa uburyo bwo guteka buvanze.
Isuzuma ry'isura nyuma yo guteka: ubuso bw'igikapu buragororotse, nta minkanyari, udusebe, ubwihindurize, kandi nta gutandukana cyangwa gusohoka.
