Nibihe bikoresho bifite umutekano kubikombe byamazi ya plastike?

Hano hari ibihumbi by'ibikombe by'amazi ya pulasitike, ni ibihe bikoresho ukwiye guhitamo kumva ufite umutekano? Kugeza ubu, hari ibikoresho bitanu by'ingenzi kubikombe by'amazi ya plastike ku isoko: PC, tritan, PPSU, PP, na PET.

Ntushobora guhitamo: PC, PET (ntuhitemo ibikombe byamazi kubantu bakuru nabana)
PC irashobora kurekura byoroshye bispenol A iyo ishyushye, na bispenol A irashobora gutera indwara ya endocrine, ikabangamira gahunda yimyororokere, kandi igatera ubwangavu bwambere mubana. Numuti udakira D-karande D!
PET ifite ubushyuhe bwa 65 ℃. Iyo ubushyuhe bwagenwe burenze, burashobora kurekura byoroshye ibintu byangiza. Ubushakashatsi bwa siyansi bwerekanye ko PET ibicuruzwa bya pulasitiki bishobora kurekura kanseri mu gihe cy’ukwezi kumwe bikoreshwa kandi bikaba ari uburozi kuri testicles.

VailableBishobora guhitamo: Tritan, PPSU, PPTritan ntabwo irimo bispenol A, bispenol S cyangwa ibintu byose bisfenol, kandi bifite umutekano muke. Nyamara, ubushyuhe bwo kurwanya tritan ni -10-96 ° C, ntabwo rero bisabwa gushyiraho amazi ashyushye ya dogere 100.
PPSU ni ibikoresho bishya bifite umutekano, polifhenylsulfone, idafite bispenol A. Imiterere yimbere yayo irahagaze neza kandi irashobora kwihanganira dogere 180 yubushyuhe bwo hejuru. Irwanya kandi kugwa, kubera ko icupa umubiri woroheje kandi ntiworoshye kumeneka.
Amacupa yumwana nibikombe byamazi bikozwe mubikoresho bya ppsu ntibishobora kubyara ibintu byuburozi nyuma yubushuhe bukabije. Ntabwo zirimo bispenol A kandi irashobora kwihanganira ubushyuhe bwo hejuru bwa dogere 180. Kubwibyo, niba umenyereye kubika amazi ashyushye cyangwa kwanduza ubushyuhe bwo hejuru, ibikoresho bya PPSU nibyo guhitamo kwambere.
Ibikombe by'amazi ya plastiki ya PP bikozwe muri polypropilene, ifite ubushyuhe bwiza nubushyuhe, bifite umutekano kandi bitagira ingaruka kumubiri wumuntu. Ariko, twakagombye kumenya ko ibikombe byamazi bikozwe muri PP bidashobora guhindurwamo ubushyuhe bwinshi mugihe kirekire, bitabaye ibyo bizatera gusaza byoroshye.
Reka turebe ibikoresho igikombe cyawe cyamazi gikozwe?
