Yihoo An333-Phenol-Dawb & Zoo Hydrolysis Kuj Antioxidant

Thaum cov tsoos phenol tsoos antioxidant tiv tauj nrog cov nitrogen thiab cov pa roj oxygen thiab nws tsim cov qauv quinone. Qinone qauv yog lub hauv paus ua rau daj kom daj thiab tau txais liab.

Phospite antioxidant tseem muaj dav siv los ua ib qho kev ua kom zoo tshaj plaws antioxidant. Txawm li cas los xij, nrog kev txhim kho txuas ntxiv ntawm EU cov txheej txheem tiv thaiv ib puag ncig, cov kev xav tau ntawm phosphite antioxidant yog ua siab dua thiab siab dua. Phospite antioxidant xav tau ntau ib puag ncig phooj ywg, tsis-toxic, tsis-phenoly resistant, thiab tiv thaiv kub.

Phospite Ntu antioxidant yog ib qho ntawm feem ntau nquag polymer stabilization additives hauv 1990s. Hauv kaum xyoo, cov qauv tshiab muaj ntau yam tshwm sim nyob rau hauv tsis kawg, tab sis feem ntau yog pentaRheathrim nplhaib qauv thiab bisphenol phosphite ester qauv. Nws txhais tau tias lub phosphate ester ensioxiliation antioxilavor technology kev txhim kho tshuab yuav tsum ua kom pom tseeb rau cov tshuab hluav taws xob ruaj khov thiab yuav ua li cas txhim kho cov hydrolytic ruaj khov.

Peb cov tsis tau-phenolic antioxidant -an333 & AN340, tsis muaj cov qauv phenolic, yog li nws tuaj yeem ua kom zoo rau cov teeb meem daj los ntawm cov qauv quinone. Kev ua qhov kub yuav nyob saum toj 180 ℃, thiab nws tau raug siv rau PU, PVC thiab lwm liaj teb los ntawm ntau tus neeg siv khoom hauv thiab txawv teb chaws hauv thiab txawv teb chaws.

Ntawm lawv, An333 tau raug pov thawj los ua qhov zoo tshaj plaws hauv PU ua npuas ncauj cov ntaub ntawv, nrog kev daj zoo heev thiab zoo hydrolysis tsis kam. Nws yog qhov zoo tshaj plaws hloov ntawm Johoku tshuaj J333e.

Dhau li ntawm cov tsis yog-phenol antioxidants, peb kuj tau muab lwm cov tshuaj ntxiv uas siv hauv PU daim ntawv thov. Hauv qab cov khoom yog rau qhov koj xaiv:
