YIHOO AN333-Phenol-Kyauta & Kyakkyawan Maganin Hydrolysis Resistance Antioxidant

Lokacin da maganin antioxidant na al'ada phenolic tare da iskar nitrogen da iskar oxygen a cikin iska, yana samar da tsarin quinone. Tsarin Qinone shine tushen dalilin launin rawaya da samun ja.

Hakanan ana amfani da antioxidant na Phosphite azaman kyakkyawan maganin antioxidant. Koyaya, tare da ci gaba da haɓaka ƙa'idodin kare muhalli na EU, buƙatun antioxidant phosphite suna ƙaruwa da girma. Phosphite antioxidant yana buƙatar zama mafi kyawun muhalli, ba mai guba ba, ba phenolic, juriya na hydrolysis, da tsayayya da zafin jiki mafi girma.

Maganin antioxidant mai taimako na Phosphite yana ɗaya daga cikin abubuwan ƙara ƙarfi na ƙarfafawa na polymer a cikin 1990s. A cikin shekaru goma, sabbin nau'ikan nau'ikan suna fitowa ba iyaka, amma ta tsarin su na sunadarai, zamu iya gano cewa sabon tsarin phosphite ya ƙunshi mafi kyawun zobe mai ƙamshi, kuma galibi sune pentaerythritol diphosphite karkace zoben zobe da tsarin bisphenol phosphite ester. Yana nufin ci gaban fasaha na antioxidant na phosphate ester yakamata ya mai da hankali kan fannoni biyu: yadda ake inganta kwanciyar hankali na injin da yadda ake inganta kwanciyar hankali na hydrolytic.

Maganin antioxidant ɗin mu na ba -phenolic -AN333 & AN340, ba ya ƙunshi tsarin phenolic, don haka yana iya guje wa matsalar rawaya da tsarin quinone ya haifar. Zazzabin sarrafawa na iya zama sama da 180 ℃, kuma abokan ciniki da yawa a ciki da waje sun yi amfani da shi a cikin PU, PVC da sauran filayen.

Daga cikin su, AN333 an tabbatar yana yin kyakkyawan aiki a cikin kayan kumfa na PU, tare da kyakkyawan juriya mai launin rawaya da juriya mai kyau na hydrolysis. Ita ce mafi kyawun maye gurbin JOHOKU Chemical JP333E.

Bayan antioxidants marasa phenol, muna kuma ba da wasu abubuwan da ake amfani da su a aikace na PU. Samfuran da ke ƙasa don zaɓin ku ne:
