Pali mitundu yambiri ya pulasitiki zopangira.Zida zapulasitiki zomwe zimagwiritsidwa ntchito popanga ndi kukonza makapu amadzi ziyenera kukhala zokonda zachilengedwe, monga PP, PS, AS, PC ndi zipangizo zina zapulasitiki.

Zopangidwa ndi zinthu zosiyanasiyana za pulasitiki ndizosiyana.Ngakhale zinthu zamtundu wa chakudya zimakhala ndi zofunikira pakugwiritsa ntchito chilengedwe, zakuthupi ndi kutentha.Zomwe tatchulazi sizidzabweretsa mavuto mukamamwa zakumwa ndi madzi ozizira kapena makapu amadzi osapitirira 60 ° C.Zida sizitulutsa zinthu zovulaza.Koma kuphwanya zofunikira zawo zakuthupi ndikusungunuka mofanana mu madzi enaake, bisphenol A yochuluka imatulutsidwa.

Panthawi imodzimodziyo, chifukwa cha kuuma kwakukulu kwa zipangizo zina zapulasitiki komanso kusagwirizana ndi kusiyana kwa kutentha, zingayambitse ming'alu panthawi yogwiritsira ntchito.Pambuyo pogwiritsidwa ntchito kwa nthawi yaitali chonchi, ming'alu ya m'kapu yamadzi idzatenga dothi lina m'madzi, ndipo chikho chamadzi choterocho sichingagwiritsidwe ntchito kwa nthawi yaitali.Makamaka mabotolo amadzi otayira, chonde onani pansi.Ambiri aiwo sangagwiritsidwe ntchito kangapo.

Chifukwa cha vuto lomwe latchulidwa pamwambapa kuti zida zapulasitiki sizingathe kusunga madzi otentha, mtundu watsopano wazinthu zapulasitiki, tritan, wawonekera pamsika.Zasinthidwa kwambiri m'mbali zonse.Choyamba, palibe bisphenol A, ndipo kachiwiri, imakhala yowonekera kwambiri, kukana kutentha kwambiri komanso kukana kwambiri.Nthawi ina tinachita mayeso.Madzi otentha otentha amathiridwa mu kapu yophunzitsira yopangidwa ndi tritan.Sanatulutse zinthu zapoizoni zilizonse ndipo chikhocho sichinapunduke.

M'mayiko ena a ku Ulaya ndi madera, chifukwa cha ziletso za pulasitiki, pali malamulo omveka bwino pa malonda a makapu amadzi apulasitiki.Makapu amadzi omwe angalowe mumsika ayenera kukhala ndi chakudya chokwanira komanso kukhala okonda zachilengedwe komanso osawononga chilengedwe.Choncho, pamene tikutsata thanzi, opanga ayamba kugwiritsa ntchito zipangizo zabwino ndi zotetezeka pokonza.

Makapu amadzi opangidwa ndi zinthu za Tritan ayikidwa mupulasitiki madzi chikhomsika kwa zaka zambiri.M'zaka zaposachedwa, akhala otchuka pamsika wapakhomo.Amalonda ambiri a makapu apulasitiki amadzi apanga zinthu za tritan, zopanda fungo komanso zopanda poizoni.Komabe, kuti mupambane pamsika, mtengo wa makapu ndi wotsika mtengo kwambiri, koma Mtengo wa zinthu za tritan wakhala wokwera mtengo kwambiri, kotero ogula akagula makapu amadzi apulasitiki, ayenera kuzindikira mosamalitsa masitayelo ndi zida zapaintaneti kuti apewe. kugula makapu abodza amadzi a tritan.
