Impande umunani zifunga impapuro zububiko hasi hasi biodegradable ikawa ipakira Hasi Yongeye gukoreshwa Gusset

Gupakira ibishyimbo bya kawa (ifu) nuburyo butandukanye bwo gupakira ikawa. Kubera ko ibishyimbo bya kawa bisanzwe bitanga karuboni ya dioxyde nyuma yo kotsa, gupakira mu buryo butaziguye birashobora kwangiza byoroshye gupakira, kandi kumara igihe kinini uhumeka ikirere bizatera impumuro nziza kandi biganisha ku mavuta nimpumuro nziza muri kawa. Oxidation yibigize itera kwangirika kwiza. Kubwibyo, gupakira ibishyimbo bya kawa (ifu) ni ngombwa cyane

Bikunze gukoreshwa mwisoko ni ugupakira ibintu, ni ibikoresho bibiri cyangwa byinshi byahujwe binyuze muburyo bumwe cyangwa bwinshi bwumye bwo gukora kugirango bipakire hamwe nibikorwa bimwe. Mubisanzwe, irashobora kugabanywamo ibice fatizo, imikorere ikora hamwe nubushyuhe bwo gufunga ubushyuhe. Igice fatizo kigira uruhare runini mubwiza, gucapa no kurwanya ubushuhe. Nka BOPP, BOPET, BOPA, MT, KOP, KPET, nibindi.; urwego rukora cyane cyane rufite uruhare rwa barrière no kurinda urumuri.

Niba warigeze guhanga amaso imifuka yikawa muri supermarket cyangwa iduka rya kawa, uzabona ko imifuka myinshi ifite umwobo muto cyangwa valve ya plastike hafi yo hejuru. Iyi valve igira uruhare runini mugukomeza ikawa nshya kandi iryoshye.

Umuyoboro ni inzira imwe ituma ibishyimbo bya kawa hamwe nikawa ya kawa irekura buhoro buhoro dioxyde de carbone (CO2) nizindi myuka ihindagurika ivuye mumufuka utabanje guhura numwuka wo hanze, uzwi kandi nka valve ikomeza gushya, valve ya aroma cyangwa ikawa indanga.

Imiti myinshi itera iyo ikawa, kandi imyuka ihindagurika nka dioxyde de carbone iba imbere mubishyimbo. Iyi myuka yongerera uburyohe ikawa, ariko ikomeza kurekura igihe gito. Nyuma yo guteka, dioxyde de carbone itangira guhunga, ariko bifata ibyumweru byinshi kugirango ibure burundu. Iyi valve ituma karuboni ya dioxyde irekurwa kandi ikabuza ogisijeni kwinjira. Iyi nzira irinda okiside kandi ikongerera igihe cyo kubaho. Iyo dioxyde de carbone irekuwe, itera umuvuduko imbere muri paki, itera gaze ya rubber ihindagurika kandi ikarekura gaze. Icyiciro cyo kurekura kirangiye, igitutu cyimbere ninyuma kiringaniye, gaze ya reberi isubira muburyo bwayo bwa mbere, hanyuma paki irongera gufungwa.

Valve nayo igufasha guhitamo ikawa yawe. Kuberako igihe nikigera impumuro yikawa izirukanwa muri valve nka dioxyde de carbone, umunuko uzaba muke nkuko ikawa ishaje. Niba ushaka kugenzura ko ibishyimbo ari bishya mbere yo kugura, urashobora gukanda buhoro umufuka kugirango urekure gaze unyuze muri valve. Ikawa ikomeye ya kawa nikimenyetso cyiza cyerekana niba ibishyimbo ari bishya, niba udahumura cyane nyuma yo gukanda byoroheje, bivuze ko ikawa itari shyashya.
