Ni irihe tandukaniro riri hagati yibikoresho bya PS nibikoresho bya AS ibikombe byamazi ya plastike

Nibihe bikoresho bikoreshwa mubikombe byamazi ya plastike kumasoko, nka Tritan, PP, PPSU, PC, AS, nibindi PS ntibikunze kuvugwa nkibikoresho bisanzwe mubikombe byamazi ya plastike. Naje kandi guhura nibyifuzo byo kugura umukiriya wiburayi. Muhinduzi yari afite ibikoresho bya PS. Inshuti nyinshi zikora ubucuruzi bwububanyi n’amahanga zizi ko isoko ry’iburayi ryose, nk’Ubudage, ryubahiriza amabwiriza yo kubuza plastike. Impamvu nuko ibikoresho bya pulasitike bitoroshye kubora no kubitunganya, kandi ibikoresho byinshi bya pulasitike birimo bispenol A, bishobora kwangiza umubiri wumuntu nyuma yo gukorwa mubikombe byamazi. Kurugero, ibikoresho bya PC, nubwo biruta AS na PS mubice bimwe byimikorere, birabujijwe kumasoko yuburayi kubyara amacupa yamazi kuko arimo bispenol A.

PS, mubisobanuro byabalayiki, ni resimoplastique resin idafite ibara kandi ibonerana hamwe na transmitance nyinshi. Ugereranije nibikoresho bya pulasitike byavuzwe haruguru, igiciro cyacyo gito ninyungu zacyo, ariko PS iroroshye kandi ifite ubukana bubi, kandi ibi bikoresho birimo ibikombe byamazi bibiri bikozwe mubikoresho bya fenol A na PS ntibishobora kuzuzwa amazi ashyushye cyane, naho ubundi bazarekura bispenol Ibintu byangiza.

AS, acrylonitrile-styrene resin, ibikoresho bya polymer, bitagira ibara kandi bibonerana, hamwe no kohereza cyane. Ugereranije na PS, irwanya kugwa, ariko ntishobora kuramba, cyane cyane ntishobora kurwanya itandukaniro ryubushyuhe. Niba wongeyeho amazi akonje nyuma yamazi ashyushye, hejuru yibikoresho bizaba Niba haribintu bigaragara, bizacika iyo bishyizwe muri firigo. Ntabwo irimo bispenol A. Nubwo kuyuzuza amazi ashyushye bizatera igikombe cyamazi kumeneka, ntabwo kizarekura ibintu byangiza, bityo gishobora gutsinda ibizamini byuburayi. Igiciro cyibikoresho kiri hejuru ya PS.
Nigute ushobora guca urubanza kubicuruzwa byarangiye niba igikombe cyamazi gikozwe mubintu bya PS cyangwa AS? Binyuze mu kwitegereza, birashobora kugaragara ko igikombe cyamazi kitagira ibara kandi kibonerana gikozwe muri ibyo bikoresho byombi bizerekana ingaruka zubururu. Ariko niba ushaka kumenya neza niba ari PS cyangwa AS, ugomba gukoresha ibikoresho byo gupima byumwuga.
