1. Monga ambiri-cholinga phenolic antioxidant.Amagwiritsidwa ntchito kwambiri pazinthu za polima, zinthu zamafuta ndi mafakitale opangira chakudya.Izi zimagwiritsidwa ntchito ngati mphira antioxidant.Zimakhala ndi zoteteza zina pa kutentha ndi ukalamba wa okosijeni, komanso zimatha kuletsa kuwonongeka kwa mkuwa.Ilibe mphamvu yotsutsa ozoni yokha, koma imatha kuteteza kuwonongeka kwa mphira wowonongeka ndi anti-ozone wothandizira ndi sera.Itha kugwiritsidwanso ntchito ngati gelling inhibitor mu rabara ya styrene butadiene.Mlingo wamba mu rabara ndi magawo 0.5-3.Pamene mlingo wawonjezeka kwa 3-5 mbali, izo sizidzapopera chisanu.Itha kugwiritsidwanso ntchito ngati stabilizer mu post-processing ndi kusunga mphira kupanga, ndipo angagwiritsidwe ntchito mphira styrene butadiene, butadiene mphira, ethylene propylene mphira, mphira chloroprene ndi mitundu ina mphira.Antioxidant 264 ndi antioxidant wamphamvu muzinthu zina za polima.Ndiwokhazikika bwino mu polyethylene, polyvinyl chloride (mlingo wa 0.01-0.1%) ndi polyvinyl ether.Antioxidant 264 ndi antioxidant yowonjezera yowonjezera pazinthu zosiyanasiyana zamafuta.Kusungunuka kwabwino kwamafuta.Izi zitha kugwiritsidwanso ntchito ngati antioxidant pamakampani opanga zakudya, omwe amagwiritsidwa ntchito muzakudya zomwe zimakhala ndi mafuta ambiri ndi mafuta.Mlingo wa mafuta, batala, nsomba zouma ndi zinthu za nkhono, nsomba ndi nkhono zochiritsidwa ndi mchere, nyama yamphongo yachisanu, ndi zina zotero ndi zosakwana 0.2g/kg, ndi zosakwana 0.75g/kg mu chingamu.Kugwiritsiridwa ntchito kwa mankhwalawa ndi kuviika njira, njira yosanganikirana mwachindunji, njira yosakaniza pambuyo pa kusungunuka kwa ethanol ndi kupopera mankhwala, ndi zina zotero. United States, Japan ndi European Community agwiritsa ntchito mankhwalawa ngati chowonjezera chovomerezeka cha chakudya, ndipo European Community imati. kuchuluka kwakukulu muzakudya ndi 150ppm, zomwe zitha kugwiritsidwa ntchito muzakudya zosiyanasiyana.

2. BHTndi mafuta osungunuka a antioxidant omwe amagwiritsidwa ntchito kwambiri kunyumba ndi kunja.Ngakhale kwambiri poizoni, koma mphamvu antioxidant, kukana kutentha ndi bata, ngakhale fungo enieni, ndipo palibe zitsulo ayoni mtundu anachita ndi zofooka zina, ndi mtengo otsika, kokha 1/5 ~ 1/8 wa BHA, China akadali ntchito monga waukulu. antioxidant.Nthawi zambiri amagwiritsidwa ntchito ndi BHA, ndi citric acid kapena ma organic acid monga synergists.Itha kugwiritsidwa ntchito mumafuta odyedwa ndi mafuta, zakudya zokazinga, makeke, Zakudyazi pompopompo, mpunga wapompopompo, mtedza wam'chitini, nsomba zouma zouma ndi zinthu zanyama zochiritsidwa, kugwiritsa ntchito kwambiri ndi 0.2g/kg.

3. Chimodzi mwazinthu zofunikira kwambiri za phenolic antioxidants.Amagwiritsidwa ntchito ngati antioxidant osaipitsa, amatha kuletsa bwino makutidwe ndi okosijeni a mpweya, kuwonongeka kwa matenthedwe ndi kuwonongeka kwa mkuwa, etc. Itha kugwiritsidwa ntchito ngati antioxidant ndi kutentha stabilizer kwa polyolefin, poliyesitala, polystyrene, utomoni wa ABS, polyvinyl kolorayidi, utomoni wa cellulose, etc. Amagwiritsidwa ntchito ngati antioxidant ndi anti-deterioration agent pa rabara yachilengedwe komanso labala yopangira monga butyl, butyl, chloroprene, nitrile, ethylene propylene ndi satin mumakampani amphira.Amagwiritsidwanso ntchito ngati antioxidant pamafuta a petroleum, mtundu wa EVA wotentha wosungunula zomatira, zokutira zamafuta osakhazikika, ndi zina. Di-tert-butyl-p-cresol ya chakudya imaloledwa kugwiritsidwa ntchito ngati antioxidant chakudya, yomwe ingagwiritsidwe ntchito mumafuta. , zowotcha, zakudya zokazinga, dzinthu, mkaka, nyama ndi zosungira.Itha kugwiritsidwanso ntchito ngati antioxidant zodzoladzola, zonunkhira, chakudya, ndi zina zambiri. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati mafuta opangira mafuta ndi mafuta owonjezera kuti apititse patsogolo kukhazikika kwamafuta.Mlingo nthawi zambiri ndi 0.05% ~ 1.0%.
