1. Raws li lub hom phiaj dav dav phenolic antioxidant.Siv dav hauv cov ntaub ntawv polymer, cov khoom siv roj av thiab kev lag luam ua zaub mov.Cov khoom no feem ntau yog siv los ua cov roj hmab antioxidant.Nws muaj qee yam kev tiv thaiv ntawm tshav kub thiab oxygen laus, thiab tuaj yeem tiv thaiv kev puas tsuaj rau tooj liab.Nws tsis muaj peev xwm tiv thaiv ozone ib leeg, tab sis nws tuaj yeem tiv thaiv kev puas tsuaj ntawm cov roj hmab vulcanized nrog cov tshuaj tiv thaiv ozone thiab siv quav ciab.Nws kuj tseem siv tau los ua gelling inhibitor hauv styrene butadiene roj hmab.Qhov dav dav npaum li cas hauv roj hmab yog 0.5-3 ntu.Thaum noj ntau npaum li 3-5 feem, nws yuav tsis tsuag Frost.Nws tseem tuaj yeem siv los ua kom ruaj khov hauv kev ua haujlwm tom qab thiab khaws cov roj hmab hluavtaws, thiab tuaj yeem siv rau hauv styrene butadiene roj hmab, butadiene roj hmab, ethylene propylene roj hmab, chloroprene roj hmab thiab lwm yam roj hmab.Antioxidant 264 yog ib qho zoo antioxidant hauv qee cov ntaub ntawv polymer.Nws yog ib qho zoo stabilizer hauv polyethylene, polyvinyl chloride (dosage 0.01-0.1%) thiab polyvinyl ether.Antioxidant 264 yog ib qho zoo heev antioxidant additive rau ntau yam roj av.Zoo roj solubility.Cov khoom no tseem tuaj yeem siv los ua antioxidant rau kev lag luam ua zaub mov, siv rau hauv cov khoom noj uas muaj roj ntau dua thiab roj.Qhov ntau npaum li cas hauv cov roj, butter, cov ntses qhuav thiab cov khoom siv plhaub ntses, cov ntses thiab cov plhaub ntses ntsev kho, cov khoom noj khov khov, thiab lwm yam yog tsawg dua 0.2g / kg, thiab tsawg dua 0.75g / kg hauv cov pos hniav.Kev siv cov khoom no yog dipping txoj kev, kev sib tov ncaj qha, sib tov txoj kev tom qab dissolving nyob rau hauv ethanol thiab txau txoj kev, thiab lwm yam. Tebchaws Asmeskas, Nyiv thiab European Community tau siv cov khoom no raws li kev cai pub noj additive, thiab European Community stipulates tias. Qhov siab tshaj plaws nyob rau hauv pub yog 150ppm, uas yuav siv tau nyob rau hauv ntau yam pub.

2. BHTyog ib qho roj-soluble antioxidant dav siv hauv tsev thiab txawv teb chaws.Txawm hais tias muaj tshuaj lom ntau dua, tab sis nws muaj peev xwm antioxidant, kub tsis kam thiab ruaj khov, tsis muaj ntxhiab tsw, thiab tsis muaj hlau ion xim cov tshuaj tiv thaiv thiab lwm yam tsis zoo, thiab tus nqi qis, tsuas yog 1/5 ~ 1/8 ntawm BHA, Tuam Tshoj tseem siv los ua lub ntsiab antioxidant.Feem ntau siv nrog BHA, thiab citric acid los yog lwm yam organic acids ua synergists.Nws tuaj yeem siv tau rau hauv cov rog thiab roj, khoom noj kib, ncuav qab zib, instant noodles, instant mov, kaus poom txiv ntoo, cov khoom ntses qhuav thiab kho cov nqaij, qhov siab tshaj plaws yog 0.2g / kg.

3. Ib qho ntawm cov hom phiaj dav dav phenolic antioxidants.Siv los ua cov tshuaj tua kab mob tsis zoo, nws tuaj yeem tiv thaiv huab cua oxidation, thermal degradation thiab tooj liab puas, thiab lwm yam. Nws tuaj yeem siv los ua antioxidant thiab kub stabilizer rau polyolefin, polyester, polystyrene, ABS resin, polyvinyl chloride, cellulose resin, thiab lwm yam. Nws yog siv los ua cov tshuaj tiv thaiv antioxidant thiab tiv thaiv kev puas tsuaj rau cov roj hmab ntuj thiab hluavtaws roj hmab xws li butyl, butyl, chloroprene, nitrile, ethylene propylene thiab satin hauv kev lag luam roj hmab.Nws kuj yog siv los ua antioxidant rau cov khoom siv roj av, EVA hom kub yaj nplaum, unsaturated fatty acid coatings, thiab lwm yam. Khoom noj khoom haus-qib di-tert-butyl-p-cresol tau tso cai siv los ua zaub mov antioxidant, uas tuaj yeem siv rau hauv cov rog. , ci khoom, kib zaub mov, cereals, khoom noj siv mis, nqaij cov khoom thiab khaws cia.Nws kuj tseem tuaj yeem siv los ua antioxidant rau tshuaj pleev ib ce, txuj lom, pub, thiab lwm yam. Tsis tas li ntawd, nws kuj tseem siv tau los ua cov roj nplua nyeem thiab roj roj ntxiv los txhim kho kev ruaj ntseg ntawm cov khoom siv roj.Qhov ntau npaum yog 0.05% ~ 1.0%.
