Uyu munsi nabonye ubutumwa bwinshuti.Umwandiko wumwimerere wabajijwe: Nibyiza gukoresha No 5 plastike cyangwa No 7 plastike kubikombe byamazi?Kubijyanye niki kibazo, nasobanuye birambuye icyo imibare nibimenyetso biri munsi yigikombe cyamazi ya plastike bivuze mubice byinshi byabanjirije.Uyu munsi nzabagezaho imibare 5 na 7. Ntabwo tuzajya muburyo burambuye kubyerekeye indi mibare.Mugihe kimwe, Inshuti zishobora kubaza ibibazo nka 5 na 7 nabo ni abahanga cyane.
Umubare 5 hepfo yikombe cyamazi ya plastike bivuze ko umubiri wigikombe cyamazi gikozwe mubikoresho bya PP.Ibikoresho bya PP bikoreshwa cyane mugukora ibikombe byamazi ya plastike.Bitewe nubushyuhe bwo hejuru bwibikoresho bya PP, ibicuruzwa byinshi birangiye bishobora gushyukwa mu ziko rya microwave muminsi yambere Agasanduku ka plastike kare ya plastike ikozwe mubintu bya PP.Ibikoresho bya PP bifite imikorere ihamye kandi ni urwego rwibiryo byemewe n'ibihugu n'uturere dutandukanye kwisi.Kubwibyo, mugukora ibikombe byamazi, ibikoresho bya PP ntabwo bikoreshwa kumubiri wigikombe gusa.Niba inshuti ziteze amatwi, bazasanga niba ari ibikombe byamazi ya plastike, ibikombe byamazi yikirahure, cyangwa ibikombe byamazi bitagira umwanda.90% by'ibipfundikizo by'igikombe cya plastiki nabyo bikozwe mubikoresho bya PP.Ibikoresho bya PP biroroshye kandi bifite ubushyuhe bwiza butandukanye.Nubwo yakuwe muri minus 20 ℃ igahita yongerwa kuri 96 water amazi ashyushye, ibikoresho ntibizacika.Ariko, niba ari AS ibikoresho, bizacika cyane kandi bizaturika bitaziguye.fungura.Kuberako ibikoresho bya PP byoroshye, ibikombe byamazi bikozwe muri PP, yaba umubiri wigikombe cyangwa umupfundikizo, bikunda gushushanya mugihe cyo gukoresha.
Umubare 7 uri hepfo yigikombe cyamazi ya plastike biragoye cyane, kuko usibye ibikoresho, nimero 7 nayo ifite ikindi gisobanuro, igereranya nibindi bikoresho bya pulasitike bifite umutekano muke.Kugeza ubu, ibikombe byamazi ya plastike byanditseho numero 7 kumasoko mubisanzwe byerekana ibi bikoresho byombi, kimwe ni PC ikindi ni Tritan.Niba rero ibikoresho byombi bigereranijwe na PP, numubare wa 5, twavuga ko icyuho ari kinini.
PC yo mu rwego rwibiribwa nayo ikoreshwa cyane mubikombe byamazi ya pulasitike nibikoresho bya pulasitiki, ariko ibikoresho bya PC birimo bispenol A, bizasohoka mugihe ubushyuhe bwo guhura burenze 75 ° C.None se kuki ikoreshwa nkibikoresho byamazi?Abahinguzi bakunze gukoresha ibikoresho bya PC mugukora ibikombe byamazi ya plastike bazagira amagambo asobanutse mugihe bagurishije, byerekana ko ibikombe nkibi byamazi bishobora gufata amazi yubushyuhe bwicyumba n’amazi akonje, kandi ntibishobora kongeramo amazi ashyushye hamwe nubushyuhe bwamazi burenga 75 ° C.Muri icyo gihe, bitewe nubushobozi bwo hejuru bwibikoresho bya PC, igikombe cyamazi cyakozwe gifite isura nziza kandi nziza.
