Kugwiritsa ntchito
Antixoidant 245 ndi mtundu wothandiza kwambiri wa asymmetric phenolic antioxidant, ndipo mawonekedwe ake apadera amaphatikizira antioxidation yabwino kwambiri, kusakhazikika pang'ono, kukana utoto wa okosijeni, chidwi chachikulu cha synergistic chokhala ndi antioxidant wothandizira (monga monothioester ndi phosphite ester), ndikupatsa zinthu nyengo yabwino. kukana pamene ntchito ndi kuwala stabilizers. Antioxidant 245 imagwiritsidwa ntchito ngati njira komanso nthawi yayitali yokhazikika ya polima ya styrene monga HIPS, ABS, MBS, ndi engineering thermoplastics ngati POM ndi PA, pomwe imagwiranso ntchito ngati choyimitsa unyolo mu polymerization ya PVC. Kuphatikiza apo, mankhwalawa alibe mphamvu pamachitidwe a polima. Mukagwiritsidwa ntchito pa HIPS ndi PVC, imatha kuwonjezeredwa ku ma monomers musanayambe polymerization.
Kulongedza ndi kusunga
Kunyamula: 25kg / thumba
Kusunga: Kukhazikika pa katundu. No wapadera chofunika koma kusunga mpweya wabwino ndi kutali ndi madzi ndi kutentha.
