Peb lub luag haujlwm tseem ceeb ntawm antioxidant
Koj puas paub dab tsi antioxidant ua? Yog koj tsis paub, tuaj saib!
1. Synergy ntawm antioxidants.
Ib qho piv txwv paub zoo yog daim ntawv thov ntawm biscinnamyl thiodipropionate (DLTDP) los yog bisstearyl thiodipropionate (DSTDP) thiab sterically hindered phenols nyob rau hauv thermal stability ntawm ib co polymers. Lwm qhov piv txwv tseem ceeb ntawm kev sib koom ua ke yog qhov sib xyaw ua ke ntawm sterically hindered phenols thiab phosphites thaum txhim kho cov yaj stability ntawm polyenes.
2. Kev ruaj ntseg ntawm cov polymers siv cov saw-tawg antioxidants.
Cov tshuaj tiv thaiv kab mob ntawm cov tshuaj tiv thaiv kab mob antioxidant cuam tshuam hauv cov tshuaj tiv thaiv kab mob, uas yog, ntu saw pub dawb mechanism (CB-D) thiab ntu saw saw txais mechanism (CB-A).
3. Stability ntawm siab polymer nrog pre-antioxidant.
Los yog tiv thaiv co-antioxidants tuaj yeem decompose hydroperoxides yam tsis tau tsim cov dawb radical intermediates, yog li lawv tuaj yeem tiv thaiv cov saw caj dab los ntawm decomposition ntawm hydroperoxides rau hauv cov dawb radicals.
