Ni bangahe uzi ku mifuka isanzwe yo gupakira ibiryo?

Hariho ubwoko bwinshi bwibifuka bipfunyika ibiryo bikoreshwa mugupakira ibiryo, kandi bifite imikorere yihariye nibiranga. Uyu munsi tuzaganira kubumenyi bukunze gukoreshwa mubifuka bipfunyika ibiryo kugirango ubone. None igikapu cyo gupakira ibiryo ni iki? Ibikapu bipfunyika ibiryo mubisanzwe bivuga plastike isa nimpapuro zifite umubyimba uri munsi ya mm 0,25 nka firime, kandi gupakira byoroshye bikozwe muri firime ya plastike bikoreshwa cyane mubiribwa. Hariho ubwoko butandukanye bwimifuka yo gupakira ibiryo. Biragaragara, byoroshye, bifite amazi meza, birwanya ubushuhe hamwe nimbogamizi ya gaze, imbaraga zumukanishi, imiti ihamye, imiti irwanya amavuta, byoroshye gucapa neza, kandi birashobora gushyirwaho ubushyuhe mumifuka. Byongeye kandi, ibisanzwe bikoreshwa mubiribwa byoroshye gupakira mubisanzwe bigizwe nibice bibiri cyangwa byinshi bya firime zitandukanye, zishobora kugabanywa mubice byo hanze, hagati no hagati imbere ukurikije imyanya yabo.

Nibihe bisabwa kugirango imikorere ya buri cyiciro gikunze gukoreshwa muri firime zipakira ibiryo byoroshye? Mbere ya byose, firime yo hanze irashobora gucapurwa, irwanya ibishushanyo, kandi irwanya itangazamakuru. Ibikoresho bisanzwe bikoreshwa harimo OPA, PET, OPP, na firime zisize. Hagati ya firime yo hagati muri rusange ifite imirimo nka bariyeri, igicucu cyumucyo, no kurinda umubiri. Ibikoresho bikunze gukoreshwa birimo BOPA, PVDC, EVOH, PVA, Ikaramu, MXD6, VMPET, AL, nibindi. Noneho hariho firime y'imbere, ubusanzwe ifite imirimo ya bariyeri, gufunga, no kurwanya itangazamakuru. Ibikoresho bisanzwe bikoreshwa ni CPP, PE, nibindi. Byongeye, ibikoresho bimwe bifite ibice byombi byo hanze ndetse no hagati. Kurugero, BOPA irashobora gukoreshwa nkigice cyo hanze cyo gucapa, kandi irashobora no gukoreshwa nkigice cyo hagati kugirango igire uruhare runini rwa bariyeri no kurinda umubiri.

Ibiribwa bikoreshwa cyane mubipfunyika bya firime biranga ibintu, mubisanzwe, ibintu byo hanze bigomba kugira ibishushanyo mbonera, kurwanya gucumita, kurinda UV, kurwanya urumuri, kurwanya amavuta, kurwanya ibintu kama, kurwanya ubukonje nubukonje, kurwanya ihungabana, gucapura, ubushyuhe buhamye, umunuko muke, Impumuro nke, idafite uburozi, glossy, mucyo, igicucu hamwe nuruhererekane rwibintu; ibikoresho byo hagati bigomba kuba bifite imbaraga zo kurwanya ingaruka, kurwanya compression, kurwanya gucumita, kurwanya ubushuhe, kurwanya gaze, kugumana impumuro nziza, kurwanya urumuri, kurwanya amavuta, kurwanya ibintu kama, kurwanya ubushyuhe nubukonje, kurwanya ihungabana, imbaraga zimpande zombi, uburyohe buke, impumuro nke, idafite uburozi, bubonerana, butanga urumuri nibindi bintu; noneho ibikoresho byimbere byimbere, hiyongereyeho ibintu bimwe bisanzwe hamwe nigice cyo hanze hamwe nigice cyo hagati, nacyo gifite imiterere yihariye yacyo, igomba kuba ifite kugumana impumuro nziza, adsorption nkeya hamwe na anti-seepage. Iterambere ryubu ryimifuka yo gupakira ibiryo nuburyo bukurikira:

1. Imifuka yo gupakira ibiryo ikozwe mubikoresho bitangiza ibidukikije.

2. Kugirango ugabanye ibiciro no kuzigama umutungo, imifuka yo gupakira ibiryo iba yoroheje.

3. Imifuka yo gupakira ibiryo iratera imbere mu cyerekezo cyimirimo idasanzwe. Ibikoresho byinshi bihuza ibikoresho bizakomeza kongera ubushobozi bwisoko. Mu bihe biri imbere, firime-barrière nyinshi hamwe nibyiza byo gutunganya byoroshye, ogisijeni ikomeye hamwe n’imyuka y’amazi yo mu mazi, hamwe n’ubuzima bwiza bwo kubaho bizahinduka inzira nyamukuru yo gupakira ibiryo byoroshye muri supermarket mugihe kizaza.
