Izi zimafuna kuganizira mozama zinthu zambiri monga momwe polimayo imagwirira ntchito, momwe imagwirira ntchito, malo ogwiritsira ntchito komanso malamulo oteteza chilengedwe.

Ma polyolefini(monga polyethylene ndi polypropylene) zimakhala ndi vuto la kutentha kwa okosijeni, zomwe zimafuna ma antioxidants oyamba (monga ma phenols) kuti agwire ma free radicals ndi ma antioxidants othandizira (monga ma phosphites) kuti awononge hydroperoxide.

PVCKuwonongeka kwa zinthu kumadalira kwambiri ionization, ndipo poyerekeza ndi ma polyolefins, opanga PVC ali ndi kufunikira kochepa kwa ma antioxidants. Pakadali pano, ma antioxidants omwe amagwiritsidwa ntchito kwambiri pa PVC ndi awa:AO1076, AO2246, ndi zina zotero.

Mapulasitiki aukadaulo(PA, PC, PPS) nthawi zambiri zimakonzedwa kutentha kwambiri ndipo zimafunikama antioxidants osatenthakuti apewe chikasu ndi kutayika kwa mphamvu.

①Pa zinthu zomwe zimakonzedwa kutentha kwambiri (>280 ℃), ndibwino kusankha mitundu yomwe siimasintha kwambiri kutentha komanso yolimba.

②Kuti mukhale panja kwa nthawi yayitali, pamafunika njira yolimbana ndi UV, monga mankhwala a phenolic ndiZoyamwa UV.

③Samalani kuti zinthu zikugwirizana ndi chilengedwe ndipo pewani mvula. Kuphatikiza apo, ma antioxidants a amine ali ndi chitetezo chofooka cha mtundu.

④Kuphatikiza kwa antioxidant yayikulu ndi antioxidant yothandizira kungathandize kwambiri pakuletsa ukalamba.

Mwachidule, kugwiritsa ntchito ma antioxidants okha sikukwanira kuthana ndi zochitika zosiyanasiyana zogwiritsidwa ntchito, ndipo kuphatikiza zowonjezera zingapo ndi chisankho chabwino.

Lumikizanani nafe kuti mudziwe zambiri!
