Ndi zinthu zotani zomwe zili zotetezeka ku makapu amadzi apulasitiki?

Pali masauzande a makapu amadzi apulasitiki, ndi zinthu ziti zomwe muyenera kusankha kuti mukhale otetezeka?Pakali pano, pali zida zisanu zazikulu za makapu amadzi apulasitiki pamsika: PC, tritan, PPSU, PP, ndi PET.

❌Sitingasankhe: PC, PET (musasankhe makapu amadzi a akulu ndi makanda)
PC imatha kutulutsa bisphenol A mosavuta ikatenthedwa, ndipo bisphenol A imatha kuyambitsa matenda a endocrine, kusokoneza ubereki, komanso kuyambitsa kutha msinkhu kwa ana. Ndi mankhwala a D osatha!
PET ili ndi kukana kutentha kwa 65 ℃. Kutentha koyezedwa kukadutsa, kumatha kutulutsa zinthu zovulaza mosavuta. Kafukufuku wasayansi wapeza kuti zinthu zapulasitiki za PET zimatha kutulutsa ma carcinogens mkati mwa mwezi umodzi wogwiritsidwa ntchito ndipo zimakhala poizoni kwa machende achimuna.

✅Zopezeka kuti musankhe: Tritan, PPSU, PPTritan zakuthupi zilibe bisphenol A, bisphenol S kapena zinthu zilizonse za bisphenol, ndipo ndizotetezeka kwambiri. Komabe, kukana kutentha kwa tritan ndi -10-96 ° C, kotero sikuvomerezeka kukhazikitsa madzi otentha a 100-degree.
PPSU ndi chinthu chatsopano chotetezeka, polyphenylsulfone, chomwe chilibe bisphenol A. Mapangidwe ake amkati ndi okhazikika ndipo amatha kupirira kutsekereza kosalekeza kwa 180-degree high-temperature. Imalimbananso kwambiri ndi kugwa, chifukwa thupi la botolo ndi lopepuka komanso losavuta kusweka.
Mabotolo a ana ndi makapu amadzi opangidwa ndi zinthu za ppsu sangatulutse zinthu zapoizoni pambuyo potseketsa mobwerezabwereza kutentha kwakukulu. Zilibe bisphenol A ndipo zimatha kupirira kutentha kwa madigiri 180. Chifukwa chake, ngati mumazolowera kusunga madzi otentha kapena kupha tizilombo toyambitsa matenda, zinthu za PPSU ndiye chisankho choyamba.
Makapu amadzi apulasitiki a PP amapangidwa ndi polypropylene, yomwe imakhala ndi kukhazikika kwamafuta komanso kutsekemera, ndi yotetezeka komanso yopanda vuto kwa thupi la munthu. Komabe, ziyenera kukumbukiridwa kuti makapu amadzi opangidwa ndi PP sangathe kutenthedwa pa kutentha kwakukulu kwa nthawi yaitali, mwinamwake angayambitse kukalamba mosavuta.
Tiyeni tiwone zomwe chikho chanu chamadzi chimapangidwa ndi zinthu ziti?
