YIHOO AN333-Fenol-Yubusa & Hydrolysis Nziza Antioxidant

Iyo antioxydants ya fenolike gakondo ihura na azote na gaze ya ogisijeni mu kirere, itanga imiterere ya quinone. Imiterere ya Qinone niyo ntandaro yo gutera umuhondo no kubona umutuku.

Antioxydants ya fosifite nayo ikoreshwa cyane nka antioxydants nziza cyane. Ariko, hamwe nogukomeza kunoza ibipimo by’ubumwe bw’ibihugu by’Uburayi, ibisabwa na antioxydants ya fosifite bigenda byiyongera. Antioxydants ya fosifike igomba kuba yangiza ibidukikije, idafite uburozi, idafite fenolike, irwanya hydrolysis, kandi irwanya ubushyuhe bwinshi.

Antioxydants ya fosifite ni kimwe mu byongera imbaraga za polymer stabilisation mu myaka ya za 90. Mu myaka icumi, ubwoko bushya bwimiterere bugaragara muburyo butagira iherezo, ariko ukurikije imiterere yimiti, dushobora kubona ko imiterere mishya ya fosifite irimo impeta yimpumuro nziza, kandi ahanini ni pentaerythritol diphosphite spiral ring ring na bisphenol fosifite ester. Bisobanura ko iterambere rya fosifate ester auxiliary antioxidant ikoranabuhanga rigomba kwibanda kubintu bibiri: uburyo bwo kunoza imashini zihamye hamwe nogutezimbere hydrolytike.

Antioxydants yacu idafite fenolike -AN333 & AN340, ntabwo irimo imiterere ya fenolike, bityo irashobora kwirinda neza ikibazo cyumuhondo cyatewe nimiterere ya quinone. Ubushyuhe bwo gutunganya bushobora kuba hejuru ya 180 ℃, kandi bwakoreshejwe muri PU, PVC nizindi nzego nabakiriya benshi mu mahanga.

Muri byo, AN333 byagaragaye ko ikora neza mubikoresho bya PU ifuro, hamwe n’umuhondo mwiza cyane hamwe n’amazi meza ya hydrolysis. Nibisimburwa byiza bya JOHOKU Chemical JP333E.

Usibye antioxydants itari fenol, tunatanga izindi nyongeramusaruro zikoreshwa muri progaramu ya PU. Hasi y'ibicuruzwa nibyo wahisemo:

Buri gihe urahawe ikaze kutwandikira kugirango ubaze ibibazo!
