YIHOO AN333-Phenol-Free & Good Hydrolysis Resistance Antioxidant

Pamene chikhalidwe cha phenolic antioxidant chimalumikizana ndi nayitrogeni ndi mpweya wa mpweya mumlengalenga, zimapanga mawonekedwe a quinone. Kapangidwe ka Qinone ndiye komwe kumayambitsa chikasu ndikufiyira.

Phosphite antioxidant imagwiritsidwanso ntchito ngati antioxidant yabwino kwambiri. Komabe, ndikuwongolera kosalekeza kwa miyezo yoteteza chilengedwe ku EU, zofunikira za phosphite antioxidant zikukula ndikukwera. Phosphite antioxidant iyenera kukhala yosavuta kuwononga chilengedwe, yopanda poizoni, yopanda phenolic, yolimbana ndi hydrolysis, ndikulimbana ndi kutentha kwambiri.

Phosphite wothandizira antioxidant ndi imodzi mwazinthu zowonjezera zowonjezera polima m'ma 1990. Zaka khumi, mitundu yatsopano yamitundu imayamba mosalekeza, koma ndimapangidwe awo, titha kupeza kuti phosphite yatsopano ili ndi mphete zonunkhira, ndipo makamaka ndi pentaerythritol diphosphite mphete yozungulira komanso bisphenol phosphite ester. Zimatanthawuza kuti chitukuko cha teknoloji ya phosphate ester yothandizira antioxidant iyenera kuyang'ana mbali ziwiri: momwe mungapangire kukhazikika kwamakina ndi momwe mungapangire kukhazikika kwa hydrolytic.

Yathu yopanda phenolic antioxidant -AN333 & AN340, ilibe mawonekedwe a phenolic, chifukwa chake imatha kupewa vuto lachikasu lomwe limayambitsidwa ndi quinone. Kutentha kotentha kumatha kukhala pamwamba pa 180 ℃, ndipo kwagwiritsidwa ntchito mu PU, PVC ndi madera ena ndi makasitomala ambiri komanso akunja.

Pakati pawo, AN333 yatsimikiziridwa kuti imagwira bwino ntchito mu zinthu zopangira thobvu za PU, ndi kukana kwabwino kwa chikaso ndi kukana kwa hydrolysis. Ndi cholowa m'malo mwa JOHOKU Chemical JP333E.

Kuphatikiza pa non-phenol antioxidants, timaperekanso zowonjezera zina zomwe zimagwiritsidwa ntchito mu PU application. Pansipa pazogulitsa ndi zomwe mungasankhe:

Mwalandilidwa kuti mutilankhule nafe pakafunso!
