Igikombe cya plastiki unywa nuburozi?

Mubuzima bwacu bwa buri munsi, amacupa ya plastike arashobora kugaragara ahantu hose.Ndabaza niba wabonye ko hari ikirangantego cyumubare kimeze nkikimenyetso cya mpandeshatu munsi yamacupa menshi ya plastike (ibikombe).

urugero:

Amacupa yamazi yubutare, yanditseho 1 hepfo;

Igikombe cyihanganira ubushyuhe bwo gukora icyayi, cyanditseho 5 hepfo;

Ibikombe by'isafuriya ako kanya n'amasanduku y'ibiryo byihuse, hepfo yerekana 6;

…

Nkuko buriwese abizi, ibirango biri munsi yaya macupa ya pulasitike bifite ibisobanuro byimbitse, bikubiyemo "uburozi bwuburozi" bwamacupa ya plastike kandi byerekana urugero rwo gukoresha ibicuruzwa bya plastiki bijyanye.

“Umubare na kode iri munsi y’icupa” ni bimwe mu bigize ibicuruzwa bya pulasitiki biteganijwe mu rwego rw’igihugu:

Ikimenyetso cya mpandeshatu itunganyirizwa munsi y icupa rya plastiki ryerekana ko gishobora gukoreshwa, naho imibare 1-7 yerekana ubwoko bwibisigarira bikoreshwa muri plastiki, bigatuma byoroshye kandi byoroshye kumenya ibikoresho bisanzwe bya plastiki.

Igikombe cya plastiki unywa nuburozi?Gusa reba imibare iri hepfo hanyuma umenye!
Ubu bwoko bwibikoresho ntabwo bufite imbaraga zo kurwanya ubushyuhe kandi bukoreshwa cyane mugukora firime ya cling na firime.

Muri rusange, firime ya PE cling yujuje ibisabwa izashonga mugihe ubushyuhe burenze 110 ° C, hasigara imyiteguro ya plastike idashobora kubora numubiri wumuntu.Byongeye kandi, iyo ibiryo bipfunyitse muri firime ya cling hanyuma bigashyuha, amavuta mubiryo azashonga byoroshye muri firime.ibintu byangiza birashonga.

Kubwibyo, birasabwa ko ibiryo bipfunyitse mubipfunyika bya pulasitike bigomba kuvaho mbere yo kubishyira mu ziko rya microwave.

“5 ″ PP - polypropilene

Igikombe cya plastiki unywa nuburozi?Gusa reba imibare iri hepfo hanyuma umenye!
Ibi bikoresho, bisanzwe bikoreshwa mugukora agasanduku ka sasita, birashobora kwihanganira ubushyuhe bwo hejuru bwa 130 ° C kandi bifite umucyo mubi.Nibisanduku byonyine bya plastiki bishobora gushyirwa mu ziko rya microwave kandi birashobora gukoreshwa nyuma yo koza neza.

Ariko, twakagombye kumenya ko udusanduku tumwe na tumwe twa sasita dufite "5 ″ hepfo, ariko" 6 ″ ku gipfundikizo.Muri iki kibazo, birasabwa ko umupfundikizo ukurwaho mugihe agasanduku ka sasita gashyizwe mu ziko rya microwave, kandi ntikabe hamwe numubiri.Shyira muri microwave.

“6 ″ PS —— Polystirene

Igikombe cya plastiki unywa nuburozi?Gusa reba imibare iri hepfo hanyuma umenye!
Ubu bwoko bwibikoresho bushobora kwihanganira ubushyuhe bwa dogere 70-90 kandi bufite umucyo mwiza, ariko ntibushobora gushyirwa mu ziko rya microwave kugirango wirinde gusohora imiti kubera ubushyuhe bukabije;no gufata ibinyobwa bishyushye bizana uburozi no kurekura styrene iyo yatwitse.Bikunze gukoreshwa mugukora Ibikoresho byubwoko bwibikombe ako kanya udusanduku twa noode hamwe nudusanduku twibiryo byihuse.

Niyo mpamvu, birasabwa kwirinda gukoresha udusanduku twibiryo byihuse mugupakira ibiryo bishyushye, cyangwa kubikoresha kugirango ufate aside ikomeye (nkumutobe wa orange) cyangwa ibintu bya alkaline ikomeye, kuko bizabora polystirene itari nziza kumubiri wumuntu kandi irashobora byoroshye kanseri.

“7” Abandi - PC hamwe nandi ma code ya plastike

Igikombe cya plastiki unywa nuburozi?Gusa reba imibare iri hepfo hanyuma umenye!
Nibikoresho bikoreshwa cyane, cyane cyane mugukora amacupa yumwana, ibikombe byo mu kirere, nibindi, ariko, byavuzweho impaka mumyaka yashize kuko birimo bispenol A;rero, witonde kandi witondere bidasanzwe mugihe ukoresheje iki kintu cya plastiki.

None, nyuma yo gusobanukirwa nubusobanuro bwibi birango bya plastiki, nigute ushobora guca "codex toxicity" ya plastiki?

Uburyo 4 bwo kumenya uburozi

(1) Kwipimisha

Imifuka ya pulasitike idafite ubumara ni amata yera, yoroheje, cyangwa adafite ibara kandi abonerana, byoroshye, byoroshye gukoraho, kandi bigaragara ko bifite ibishashara hejuru;imifuka ya pulasitike yubumara ifite ibara ryijimye cyangwa umuhondo wijimye wijimye kandi wumva ufashe.

(2) Kumenya Jitter

Fata impera imwe yumufuka wa plastike hanyuma uyinyeganyeze cyane.Niba ikora ijwi ryumvikana, ntabwo ari uburozi;niba ikora amajwi atuje, ni uburozi.

(3) Gupima amazi

Shira igikapu cya plastiki mumazi hanyuma ukande hasi.Umufuka wa pulasitike udafite uburozi ufite uburemere buke bwihariye kandi urashobora kureremba hejuru.Umufuka wa pulasitiki ufite ubumara ufite uburemere bunini bwihariye kandi uzarohama.

(4) Kumenya umuriro

Imifuka ya pulasitike idafite ubumara ya polyethylene irashya, hamwe numuriro wubururu hejuru hejuru yumuhondo.Iyo yaka, itonyanga nk'amarira ya buji, impumuro ya paraffine, kandi itanga umwotsi muke.Amashashi ya pulasitiki ya polyvinyl ya chloride yangiza ntabwo yaka kandi azimya akimara gukurwa mumuriro.Numuhondo hamwe nicyatsi kibisi, irashobora gukomera mugihe yoroshye, kandi ifite impumuro nziza ya acide hydrochloric.
