Polymer-ka ayaa sida caadiga ah ku jira xaalad anoxic ah oo hoos yimaada xaaladaha habaynta extrusion, nidaamkuna wuxuu ka kooban yahay tiro badan oo kaarboon ah halkii uu ka ahaan lahaa xagjirka alkoxy iyo hydroxyl radicals.Sidaa darteed, xasiliyaha farsamaynta ku habboon waa inuu awood u yeesho inuu si wax ku ool ah u qabto xag-jirayaasha kaarboonka.Antioxidant-ka hydroxylamine ee kor ku xusan waa nooc ka mid ah wakiilka dabin kaarboonka.
Wakiilada dabinka kaarboonka bilaashka ah ee ugu muhiimsan ee suuqa waa hydroxylamine, bisphenol mono-acrylate, ortho acrylyl phenol la beddelay iyo benzofuranone dhowr qaybood.
Bisphenol monoacrylate antioxidants:
Unugyada bisphenol monoacrylate molecules, kaarboonka kaarboonka waxaa qabta kooxda acrylyl, iyo enol radicals-ka la soo saaray waxaa loo rogi karaa radicals oksijiin phenolic ah oo deggan kooxda hydroxyl ee isla molecule.Saamayntan waxaa loo yaqaan habka xasilinta laba-shaqaale.Tani waxay siinaysaa bisphenol monoacrylate awood dabin xag-jir ah oo xor ah oo aad u xooggan.Xasilinteedu waa mid xoogan xitaa heerkulka sare.Shirkado ku yaal Japan iyo Yurub ayaa bilaabay badeecadahaas.Waqtigan xaadirka ah, Sumilizer GM ee Sumitomo Chemical, IRGANOX 3052 ee BASF, iyo AO3352/AO3353 ayaa inta badan lagu isticmaalaa suuqa.
