3 - PVC polyvinyl chloride
Bikunze kwambara amakoti yimvura, ibikoresho byubwubatsi, firime ya plastike, agasanduku ka plastiki, nibindi. Ifite plastike nziza nigiciro gito, kuburyo ikoreshwa cyane.Kurwanya ubushyuhe bigera ku rwego rwo hejuru iyo bigeze kuri 81 ° C.Biroroshye kubyara ibintu byangiza mubushyuhe bwinshi, kandi ntibikunze gukoreshwa mubipfunyika ibiryo.Biragoye koza, byoroshye kuguma, ntugasubiremo.
4 - PE polyethylene
Bikunze kuboneka mubipfunyika bya pulasitike, firime ya pulasitike, nibindi. Ku bushyuhe bwinshi, hakorwa ibintu byangiza.Nyuma yuko ibintu byuburozi byinjiye mumubiri wumuntu hamwe nibiryo, birashobora gutera indwara nka kanseri yamabere nudusembwa twavutse.
5 - PP polypropilene
Bikunze kuboneka mumacupa y amata ya soya, amacupa ya yogurt, hamwe nagasanduku ka sasita ya microwave.Ingingo yo gushonga ni hejuru ya 167 ° C.Nibicuruzwa bya plastiki bishobora gushyirwa mu ziko rya microwave kandi birashobora gukoreshwa nyuma yo koza neza.Twabibutsa ko kubisanduku bimwe bya sasita ya microwave, agasanduku k'umubiri gakozwe muri No 5 PP, ariko umupfundikizo ukorwa No 1 PET.Kubera ko PET idashobora kwihanganira ubushyuhe bwo hejuru, ntishobora gushyirwa mu ziko rya microwave hamwe nagasanduku k'umubiri.
6 - PS polystirene
Bikunze kuboneka mubikombe byamasanduku ya noode ako kanya hamwe nagasanduku k'ibiryo byihuse.Ntugashyire mu ziko rya microwave, kuko ishobora kurekura imiti yangiza kubera ubushyuhe bwinshi.Irinde gupakira ibiryo bishyushye mumasanduku yibiryo byihuse, kandi ntukoreshe microwave ako kanya mubikombe.
7 - ubundi bwoko bwa PC
Bikunze kuboneka mu ndobo, ibikombe byo mu kirere, no kugaburira amacupa.Amaduka yishami akoresha ibirahure nkimpano.Nyamara, ibikombe byamazi bikozwe muri ibi bikoresho birashobora kurekura byoroshye ibintu byuburozi bisphenol A, byangiza umubiri wumuntu.Kandi, ntugashyuhe cyangwa ngo ushire izuba mugihe ukoresheje icupa ryamazi.
