Iyo polymer inowanzo iri mune anoxic state pasi pe extrusion processing mamiriro, uye sisitimu yacho ine huwandu hukuru hwekabhoni radicals pane alkoxy radicals uye hydroxyl radicals.Naizvozvo, iyo yakakodzera kugadzirisa stabilizer inofanirwa kukwanisa kubata kabhoni yemahara radicals zvinobudirira.Iyo hydroxylamine antioxidant yataurwa pamusoro imhando yekabhoni radical trapping agent.
Iwo makuru kabhoni akasununguka radical ekuteya maajenti pamusika hydroxylamine, bisphenol mono-acrylate, ortho acrylyl inotsiva phenol uye benzofuranone akati wandei mapoka.
Bisphenol monoacrylate antioxidants:
Mu bisphenol monoacrylate molecules, iyo carbon radical inotorwa neboka re acrylyl, uye enol radicals inogadzirwa inogona kuchinjwa kuva yakagadzikana phenolic okisijeni radicals ne hydroxyl inoshanda boka mune imwechete molecule.Mhedzisiro iyi inozivikanwa sebifunctional stabilization mechanism.Izvi zvinopa bisphenol monoacrylate yakasimba kwazvo yemahara radical yekuteya kugona.Kugadzikana kwayo kwakasimba kunyange pakupisa kwakanyanya.Makambani muJapan neEurope akatanga zvigadzirwa zvakadaro.Parizvino, Sumilizer GM neSumitomo Chemical, IRGANOX 3052 neBASF, uye AO3352/AO3353 inonyanya kushandiswa pamusika.
