1. E pei o le phenolic antioxidant masani. Fa'aaoga lautele i mea polymer, oloa suauu ma alamanuia gaosi meaai. O lenei oloa e masani ona faʻaaogaina e fai ma paʻu antioxidant. E i ai se aafiaga puipuia i luga o le vevela ma le okesene matua, ma e mafai foi ona taofia le faaleagaina apamemea. E leai se malosi e tetee atu ai i le osone na o ia, ae e mafai ona puipuia le faaleagaina o le pa'u vulcanized i le anti-ozone agent ma le ga'o. E mafai fo'i ona fa'aaogaina e fai ma fa'agata gelling i pa'u styrene butadiene. Ole fua masani ile paʻu ole 0.5-3 vaega. A faʻateleina le vailaʻau i le 3-5 vaega, e le faʻafefe ai le kiona. E mafai foi ona faʻaaogaina e avea o se stabilizer i le post-processing ma le teuina o paʻu gaosia, ma e mafai ona faʻaaogaina i le paʻu styrene butadiene, paʻu butadiene, paʻu ethylene propylene, paʻu chloroprene ma isi ituaiga paʻu. Antioxidant 264 ose antioxidant aoga i nisi mea polymer. O se faʻamautu lelei i polyethylene, polyvinyl chloride (dosage 0.01-0.1%) ma polyvinyl eter. O le Antioxidant 264 o se mea fa'aopoopo fa'aantioxidant lelei mo oloa suau'u eseese. Lelei solubility suauu. O lenei oloa e mafai foi ona faʻaaogaina e avea o se antioxidant mo le gaosiga o meaʻai, faʻaaogaina i meaʻai e tele suauʻu ma gaʻo. Ole fua ole ga'o, pata, i'a mamago ma oloa figota, i'a ma figota masima oloa fa'amālōlōina, mea fa'a'aisa aano o tafola, ma isi. e itiiti ifo i le 0.2g/kg, ae itiiti ifo ile 0.75g/kg ile lamu. O le faʻaaogaina o lenei oloa o le faʻaaogaina o auala, auala faʻafefiloi saʻo, auala faʻafefiloi pe a uma ona faʻamavaeina i le ethanol ma le faʻaogaina o auala, ma isi. o le aofaʻi maualuga i le fafaga e 150ppm, lea e mafai ona faʻaaogaina i fafaga eseese.

2. BHTo se suau'u-soluble antioxidant fa'aaogaina lautele i le fale ma fafo. E ui lava e sili atu ona oona, ae o lona malosi antioxidant, teteʻe vevela ma le mautu, e le o se manogi faapitoa, ma e leai se tali uʻamea lanu lanu ma isi faaletonu, ma le tau maualalo, na o le 1/5 ~ 1/8 o le BHA, o loʻo faʻaaogaina pea Saina e avea ma autu autu. antioxidant. E masani ona faʻaaogaina ma le BHA, ma le citric acid poʻo isi vailaʻau faʻalaʻau e pei o le synergists. E mafai ona faʻaaogaina i gaʻo ma suauʻu meaʻai, meaʻai falai, kuki, saimini vave, araisa vave, apa nati, oloa iʻa mamago ma meaʻai faʻamalolo, o le maualuga o le faʻaaogaina o le 0.2g/kg.

3. O se tasi o phenolic antioxidants masani. Faʻaaogaina e avea o se antioxidant e le faʻaleagaina, e mafai ona faʻafefeina lelei le faʻamaʻiina o le ea, faʻaleagaina vevela ma faʻaleagaina kopa, ma isi. E faʻaaogaina e fai ma sui antioxidant ma anti-deterioration agent mo paʻu faʻanatura ma paʻu gaosia e pei o le butyl, butyl, chloroprene, nitrile, ethylene propylene ma satin i pisinisi pa'u. E faʻaaogaina foʻi e fai ma antioxidant mo oloa suauʻu, EVA ituaiga vevela liusua pipii, unsaturated fatty acid coatings, ma isi meaʻai-grade di-tert-butyl-p-cresol e faʻatagaina e faʻaaogaina e fai ma meaʻai antioxidant, lea e mafai ona faʻaaogaina i gaʻo. , mea tao tao, mea'ai falai, cereals, oloa susu, oloa aano o manufasi ma fa'asao. E mafai foʻi ona faʻaaogaina e fai ma antioxidant mo mea teuteu, mea manogi, fafaga, ma isi. E le gata i lea, e mafai foi ona faʻaaogaina e avea ma mea faʻapipiʻi faʻapipiʻi ma suauʻu suauu e faʻaleleia ai le mautu o oloa suauu. Ole fua ole masani ole 0.05%~1.0%.
