Ndi mtundu wolemera kwambiri wamamolekyu wolepheretsa phenolic antioxidant, wogwirizana bwino ndi utomoni, kukana kuchotsa, kutsika kwamphamvu, kukana kwa oxygen komanso kutsekemera kwamagetsi.Ndikoyenera kukhazikika kwa oxygen kukhazikika kwa ma polima osiyanasiyana ndi zinthu zachilengedwe, makamaka ndi phosphite, thioester, benzofuranone, carbon radical capture agent ndi zina zothandizira antioxidant.Mu kutentha kwambiri processing ndi mkulu m'zigawo kukana ntchito kupereka mankhwala kukhazikika bwino processing ndi kukhazikika kwamuyaya.
Magawo ogwiritsira ntchito amaphatikizapo polyolefin, PET ndi poliyesita ina ya thermoplastic ndi PBT, polyamide, styrene resin ndi elastomer zipangizo monga polyurethane ndi mphira wachilengedwe.Makamaka oyenera kutentha kwambiri processing wa polyolefin (monga PP, Pe, etc.) chitoliro, jekeseni akamaumba mankhwala, waya ndi chingwe ndi zinthu zina processing kumunda.Komanso, chifukwa alibe poizoni, osaipitsa, amatha kukhala ndi mtundu wabwino wa pulasitiki, kotero ukhoza kugwiritsidwa ntchito pokhudzana ndi zipangizo zopangira chakudya.
Onjezani kuchuluka: nthawi zambiri 0.05% -1.0%, kuchuluka kwapadera kumatsimikiziridwa malinga ndi kuyesa kwa kasitomala.
Onyamula 20 Kg / 25 Kg kraft pepala thumba kapena katoni.
Sungani moyenera m'malo owuma, opanda mpweya wabwino pansi pa 25 C kuti musakhudzidwe ndi zoyatsira.Nthawi ya alumali ndi zaka ziwiri
