Gahunda yo Kumenyekanisha Plastike

Intego yambere yo gutunganya imyanda ya pulasitike ni ugutunganya ibikoresho nkibikoresho byo kurinda amikoro make no kurangiza gutunganya ibikoresho byabitswe.Muri byo, 28% by'amacupa ya PET (polyethylene terephthalate) akoreshwa mu binyobwa bya karubone arashobora gutunganywa, kandi HD-PE (polyethylene yuzuye cyane) na HD-PE y'amacupa y’amata nayo ashobora gukoreshwa neza.Kugirango byoroherezwe gutunganya ibicuruzwa bitandukanye bya plastiki nyuma yo kubikoresha, birakenewe gutondeka ubwoko butandukanye bwibicuruzwa bya pulasitiki.Kuberako hariho imiyoboro myinshi kandi igoye yo gukoresha plastike, biragoye gutandukanya ubwoko bumwebumwe bwibicuruzwa bya pulasitike nyuma yo kubikoresha gusa kubigaragara.Kubwibyo, nibyiza gushira akamenyetso kubintu byibikoresho bya plastiki.Ni ubuhe buryo bukoreshwa, ibyiza n'ibibi bya code zitandukanye?Ibiri muri gahunda yo kumenyekanisha plastike ya SPI bizatangizwa hepfo.

Izina rya plastike - kode hamwe na kode ihinnye ni ibi bikurikira:

Polyester - 01 PET(PET icupa), nkaicupa ryamaziicupa ryibinyobwa bya karubone.Igitekerezo: Ntugakoreshe amazi ashyushye mumacupa y'ibinyobwa.

Koresha: Irwanya ubushyuhe kuri 70 and, kandi irakwiriye gusa kuzuza ibinyobwa bishyushye cyangwa ibinyobwa bikonje.Niba yuzuyemo amazi yubushyuhe bwo hejuru cyangwa ashyushye, biroroshye guhinduka, kandi ibintu byangiza umubiri wumuntu bizashonga.Byongeye kandi, abahanga basanze nyuma y’amezi 10 yo gukoresha, plastike ya 1 ishobora kurekura kanseri DEHP, yangiza ibizamini.Kubwibyo, mugihe icupa ryibinyobwa rimaze gukoreshwa, ujugunye kure, kandi ntukoreshe nk'igikombe cyamazi cyangwa ikintu cyabitswe kugirango utware ibindi bintu, kugirango wirinde guteza ibibazo byubuzima.

Umuvuduko mwinshi polyethylene - 02 HDPE, nkagusukura ibicuruzwan'ibikoresho byo kwiyuhagira.Igitekerezo: Ntabwo byemewe gusubiramo niba isuku ituzuye.

Koresha: Irashobora gukoreshwa nyuma yo gukora isuku witonze, ariko ibyo bikoresho ntabwo byoroshye kubisukura.Ibicuruzwa byambere byogusukura bigumaho kandi bigahinduka ikibanza cya bagiteri.Byaba byiza utongeye kubisubiramo.

PVC - 03 PVC, nkibikoresho bimwe byo gushushanya

Koresha: Ibi bikoresho byoroshye kubyara ibintu byangiza iyo bishyushye, ndetse bizanasohoka mugihe cyo gukora.Nyuma yuko ibintu byuburozi byinjiye mumubiri wumuntu hamwe nibiryo, birashobora gutera kanseri yamabere, inenge zavutse zimpinja nizindi ndwara.Kugeza ubu, ibikoresho bikozwe muri ibi bikoresho ntibikoreshwa cyane mu gupakira ibiryo.Niba ikoreshwa, ntukareke gushyuha.

Ubucucike buke polyethylene - 04 LDPE, nka firime ibika neza, firime ya pulasitike, nibindi. Icyifuzo: Ntugapfundikire igipfunyika cya plastike hejuru yibyo kurya mu ziko rya microwave

Koresha: Kurwanya ubushyuhe ntabwo bikomeye.Mubisanzwe, PE yujuje ibyangombwa byo kubika neza bizashonga mugihe ubushyuhe burenze 110 ℃, hasigara ibintu bimwe na bimwe bya plastiki bidashobora kubora numubiri wumuntu.Byongeye kandi, niba ibiryo bipfunyitse bipfunyitse kugirango bishyushya, amavuta yo mu biryo arashobora gushonga byoroshye ibintu byangiza mubipfunyika bya plastiki.Kubwibyo, iyo ibiryo bishyizwe mu ziko rya microwave, firime ipfunyitse igomba kubanza gukurwaho.

Polypropilene - 05 PP(ishoboye kwihanganira ubushyuhe buri hejuru ya 100 ℃), nkaagasanduku ka sasita ya microwave.Igitekerezo: Kuraho igifuniko mugihe ubishyize mu ziko rya microwave

Koresha: Agasanduku konyine ka plastiki gashobora gushyirwa mu ziko rya microwave irashobora gukoreshwa nyuma yo koza neza.Byakagombye kwitabwaho cyane kuri microwave ifuru ya sasita ya sasita.Agasanduku k'umubiri kagizwe na No 5 PP, ariko igifuniko cy'agasanduku gikozwe muri No 1 PE.Kubera ko PE idashobora kwihanganira ubushyuhe bwo hejuru, ntishobora gushyirwa mu ziko rya microwave hamwe nagasanduku k'umubiri.Kugirango ube muruhande rwumutekano, kura igifuniko mbere yo gushyira kontineri mu ziko rya microwave.

Polystirene - 06 PS.

Icyifuzo: Ntukoreshe ifuru ya microwave kugirango uteke ibikombe bya noode ihita: irwanya ubushyuhe kandi irwanya ubukonje, ariko ntishobora gushyirwa mu ziko rya microwave kugirango wirinde gusohora imiti kubera ubushyuhe bwinshi.Kandi ntishobora gukoreshwa mu gupakira aside ikomeye (nk'umutobe wa orange) hamwe n'ibintu bikomeye bya alkaline, kuko izabora polystirene mbi ku mubiri w'umuntu kandi byoroshye gutera kanseri.Kubwibyo, ugomba kugerageza kwirinda gupakira ibiryo bishyushye mumasanduku yibiryo byihuse.

Andi ma code ya plastike - 07 Ibindinka: isafuriya, igikombe, icupa ryamata

Igitekerezo: kole ya PC irashobora gukoreshwa mugihe cyo gusohora ubushyuhe bisphenol A: ni ibikoresho bikoreshwa cyane cyane mumacupa y amata.Ntibivugwaho rumwe kuko birimo bispenol A. Lin Hanhua, umwarimu wungirije mu ishami ry’ibinyabuzima na chimie muri kaminuza y’Umujyi wa Hong Kong, yavuze ko mu buryo bw'igitekerezo, igihe cyose BPA ihinduwe mu buryo bwa plastike 100% mu gihe cyo gukora PC , bivuze ko ibicuruzwa bidafite BPA, ureke kubirekura.Ariko, niba bike bya bispenol A idahinduwe muburyo bwa plastiki ya PC, irashobora kurekurwa mubiryo cyangwa ibinyobwa.Kubwibyo, ni ngombwa kwitonda mugihe ukoresheje iki kintu cya plastiki.
