Anzanu osamala apeza kuti mabotolo ambiri apulasitiki adzakhala ndi manambala ndi njira zina zosavuta, ndiye manambalawa akuyimira chiyani?
"01": Ndi bwino kutaya mutamwa, osamva kutentha mpaka 70 ° C.Nthawi zambiri amagwiritsidwa ntchito muzakumwa zam'mabotolo monga madzi amchere ndi zakumwa za carbonated.Sangathe kudzazidwa ndi madzi otentha ndipo ndi oyenera zakumwa zotentha kapena zozizira.Zamadzimadzi zotentha kwambiri kapena zotenthetsera zimatha kupunduka komanso kusungunula zinthu zomwe zimawononga thupi la munthu.
"02": Sitikulimbikitsidwa kugwiritsidwa ntchito ngati chidebe chamadzi, ndipo kukana kutentha ndi 110 ° C.Nthawi zambiri amapezeka m'matumba apulasitiki okhala ndi zinthu zoyeretsera, zosambira, kapena matumba apulasitiki omwe amagwiritsidwa ntchito m'malo ogulitsira.Imatha kupirira kutentha kwa 110 ° C, ndipo imatha kugwiritsidwa ntchito kusungira chakudya ngati yalembedwa kuti ndi chakudya.
"03": sichingatenthedwe, chosagwira kutentha 81 ℃.Zofala mu ma raincoats ndi mafilimu apulasitiki.Zopangidwa ndi pulasitiki za zinthuzi zimatha kupanga zinthu ziwiri zapoizoni komanso zovulaza, imodzi ndi monomolecular vinyl chloride yomwe siyimapangidwa polima panthawi yopanga, ndipo inayo ndi zinthu zovulaza mu plasticizer.Zinthu ziwirizi ndizosavuta kutulutsa zikakumana ndi kutentha kwambiri komanso mafuta, ndipo zikalowa mwangozi m'thupi la munthu, zitha kuyambitsa khansa.Choncho, kawirikawiri amagwiritsidwa ntchito kupanga chikho.Mukagula kapu yapulasitiki yazinthuzi, chonde musalole kuti itenthe.
"04": Pa 110 ° C, padzakhala chodabwitsa chosungunuka.Zosamva kutentha, 110°C.Amagwiritsidwa ntchito popanga filimu yotsamira ndi filimu yapulasitiki, kukana kutentha sikuli kolimba.Kutentha kukapitilira 110 ℃, kukulunga kwa pulasitiki koyenerera kumawonekera kusungunuka, ndikusiya zokonzekera zapulasitiki zomwe sizingavundike ndi thupi la munthu.Ngati atakulungidwa kunja kwa chakudya ndikutenthedwa nthawi yomweyo, mafuta omwe ali m'zakudya amatha kusungunula zinthu zovulaza mu pulasitiki.
