Plastike yo mu rwego rwibiryo igabanijwemo: PET (polyethylene terephthalate), HDPE (polyethylene yuzuye), LDPE (polyethylene yuzuye), PP (polypropilene), PS (polystirene), PC nibindi byiciro

PET (polyethylene terephthalate)

Ibikoreshwa bisanzwe: amacupa yamazi yubusa, amacupa yibinyobwa ya karubone, nibindi
Amacupa yamazi yubusa hamwe nuducupa twibinyobwa bya karubone bikozwe muri ibi bikoresho.Amacupa yo kunywa ntashobora gukoreshwa mu mazi ashyushye, kandi ibi bikoresho birwanya ubushyuhe bugera kuri 70 ° C.Irakwiriye gusa kubinyobwa bishyushye cyangwa bikonje, kandi bigahinduka byoroshye iyo byuzuyemo amazi yubushyuhe bwo hejuru cyangwa ashyushye, hamwe nibintu byangiza abantu bisohoka.Byongeye kandi, abahanga basanze nyuma y’amezi 10 yo gukoresha, iki gicuruzwa cya pulasitiki gishobora kurekura kanseri yangiza abantu.

Kubera iyo mpamvu, ibinyobwa byokunywa bigomba gutabwa iyo birangiye ntibikoreshwe nkibikombe cyangwa ibikoresho byo kubikamo ibindi bintu kugirango wirinde ibibazo byubuzima.
PET yakoreshejwe bwa mbere nka fibre synthique, ndetse no muri firime na kaseti, kandi mu 1976 gusa yakoreshejwe mumacupa y'ibinyobwa.PET yakoreshejwe nkuwuzuza mubisanzwe bizwi nka 'PET icupa'.

Icupa rya PET rifite ubukana buhebuje no gukomera, biroroshye (1/9 kugeza 1/15 gusa cyuburemere bwicupa ryikirahure), byoroshye gutwara no gukoresha, bitwara ingufu nke mubikorwa, kandi ntibishobora kwinjizwa, bidahindagurika kandi birwanya kuri acide na alkalis.

Mu myaka yashize, yahindutse ikintu cyingenzi cyuzuza ibinyobwa bya karubone, icyayi, umutobe wimbuto, amazi yapakiye, vino na soya ya soya, nibindi. , n'ibinyobwa bisindisha byakoreshejwe ari byinshi mumacupa.

HDPE(Umuvuduko mwinshi Polyethylene)

Ibikoreshwa bisanzwe: gusukura ibicuruzwa, ibicuruzwa byo koga, nibindi
Ibikoresho bya plastiki byoza ibikoresho, ibikoresho byo kwiyuhagira, imifuka ya pulasitike ikoreshwa mu maduka manini no mu maduka acururizwamo ahanini bikozwe muri ibi bikoresho, birashobora kwihanganira ubushyuhe bwo hejuru 110,, byanditseho imifuka ya pulasitike y'ibiryo bishobora gukoreshwa mu gufata ibiryo.Ibikoresho bya pulasitiki byo gusukura ibicuruzwa n’ibikoresho byo kwiyuhagira birashobora kongera gukoreshwa nyuma yo gukora isuku neza, ariko ibyo bikoresho mubisanzwe ntibisukurwa neza, hasigara ibisigazwa byibicuruzwa byabanje gukora isuku, bikabihindura ahantu ho kororoka kwa bagiteri no gusukura bituzuye, nibyiza rero kutabikora kubitunganya.
PE ni plastiki ikoreshwa cyane mu nganda no mubuzima, kandi muri rusange igabanijwemo ubwoko bubiri: polyethylene yuzuye (HDPE) na polyethylene (LDPE).HDPE ifite aho ishonga kuruta LDPE, irakomeye kandi irwanya isuri y'amazi yangirika.

LDPE iragaragara hose mubuzima bwa kijyambere, ariko ntibiterwa na kontineri ikozwemo, ariko kubera imifuka ya plastike ushobora kubona ahantu hose.Byinshi mumifuka ya plastike na firime bikozwe muri LDPE.

LDPE (Ubucucike buke Polyethylene)

Ibikoreshwa bisanzwe: gufata firime, nibindi.
Cling firime, firime ya plastike, nibindi byose bikozwe muri ibi bikoresho.Kurwanya ubushyuhe ntabwo bikomeye, mubisanzwe, byujuje ibyangombwa bya firime cling mubushyuhe burenga 110 ℃ bizagaragara ko bishushe, bizasiga umubiri wumuntu udashobora kubora ibintu bya plastiki.Nanone, iyo ibiryo bishyushye muri firime ya cling, amavuta mubiryo arashobora gushonga byoroshye ibintu byangiza muri firime.Kubwibyo, ni ngombwa gukuramo igipfunyika cya pulasitike mu biryo muri microwave mbere.

PP (polypropilene)

Ibikoreshwa bisanzwe: agasanduku ka sasita ya microwave
Agasanduku ka sasita ya Microwave gakozwe muri ibi bikoresho, birwanya 130 ° C kandi bifite umucyo mubi.Nibisanduku byonyine bya plastiki bishobora gushyirwa muri microwave kandi birashobora gukoreshwa nyuma yo koza neza.

Ni ngombwa kumenya ko ibikoresho bimwe na bimwe bya microwave bikozwe muri PP 05, ariko igipfundikizo gikozwe muri PS 06, gifite umucyo mwiza ariko ntigishobora kwihanganira ubushyuhe bwinshi, bityo ntigishobora gushyirwa muri microwave hamwe na kontineri.Kugirango ube muruhande rwumutekano, kura umupfundikizo mbere yo gushyira kontineri muri microwave.
PP na PE birashobora kuvugwa ko ari abavandimwe babiri, ariko ibintu bimwe na bimwe byumubiri nubukanishi biruta PE, kubwibyo abakora amacupa bakunze gukoresha PE kugirango bakore umubiri w icupa, kandi bagakoresha PP bafite imbaraga nimbaraga nyinshi kugirango bakore ingofero no gufata .

PP ifite aho ishonga cyane ya 167 ° C kandi irwanya ubushyuhe, kandi ibicuruzwa byayo birashobora guhinduka.Amacupa akunze gukorwa muri PP ni amata ya soya nuducupa twamata yumuceri, hamwe nuducupa kumitobe yimbuto nziza 100%, yogurt, ibinyobwa by umutobe, ibikomoka kumata (nka pudding), nibindi. Ibikoresho binini, nk'indobo, amabati, imyenda yo kumesa, ibitebo, ibiseke, nibindi, bikozwe muri PP.

PS (polystirene)

Ibikoreshwa bisanzwe: ibikombe by'agasanduku ka noode, agasanduku k'ibiryo byihuse
Ibikoresho byakoreshwaga mu gukora ibikombe bya noode hamwe nudusanduku twibiryo byihuse.Nubushyuhe nubukonje, ariko ntibishobora gushyirwa mu ziko rya microwave kugirango wirinde gusohora imiti kubera ubushyuhe bwinshi.Ntigomba gukoreshwa kuri acide ikomeye (urugero umutobe wa orange) cyangwa ibintu bya alkaline, kuko polystirene, mbi kubantu, irashobora kubora.Kubwibyo, ugomba kwirinda gupakira ibiryo bishyushye mubikoresho byihuse byihuse.
PS ifite amazi make kandi ihagaze neza, kuburyo ishobora guterwa inshinge, gukanda, gusohora cyangwa gushyuha.Irashobora guterwa inshinge, gukanda, kubisohora hamwe na thermoformed.Mubisanzwe ishyirwa mubikorwa nkibibyimba cyangwa bidafite ifumbire ukurikije niba byarabaye "ifuro".

PCn'abandi

Ibikoreshwa bisanzwe: amacupa yamazi, imifuka, amacupa y amata
PC ni ibikoresho bikoreshwa cyane, cyane cyane mu gukora amacupa y’amata n’ibikombe byo mu kirere, kandi ntibivugwaho rumwe kuko birimo Bisphenol A. Impuguke zerekana ko mubitekerezo, igihe cyose BPA ihinduwe 100% muburyo bwa plastike mugihe cyo gukora PC, bivuze ko ibicuruzwa ari BPA rwose, tutibagiwe ko bitasohotse.Ariko, niba umubare muto wa BPA udahinduwe muburyo bwa plastiki ya PC, irashobora kurekurwa mubiribwa cyangwa ibinyobwa.Kubwibyo, hagomba kwitonderwa cyane mugihe ukoresheje ibyo bikoresho bya plastiki.
Ubushyuhe bwo hejuru bwa PC, niko BPA irekurwa kandi ikarekurwa vuba.Kubwibyo, amazi ashyushye ntagomba gutangwa mumacupa yamazi ya PC.Niba isafuriya yawe ari numero 07, ibikurikira birashobora kugabanya ibyago: Ntugashyuhe mugihe ukoresheje kandi ntukabishyire kumurasire yizuba.Ntukarabe isafuriya mu koza cyangwa koza ibikoresho.

Mbere yo kuyikoresha bwa mbere, kwoza na soda yo guteka n'amazi ashyushye hanyuma uyumishe bisanzwe mubushyuhe bwicyumba.Nibyiza guhagarika gukoresha kontineri niba ifite ibitonyanga cyangwa ivunika, kuko ibicuruzwa bya plastiki birashobora kubika byoroshye bagiteri niba bifite ubuso bwiza.Irinde gukoresha inshuro nyinshi ibikoresho bya pulasitike byangiritse.
