Cov Ntawv Thov
4,4 {- butylidenebis (6 - Tertically istolers hindolant dav siv nyob rau hauv polymers, elastomers, roj nplua, thiab roj. Nws yog qhov tshwj xeeb ua tau zoo rau hauv cov yas xws li polyethylene xws li polyethylene xws li polyethylene xws li polyethylene, polypropylene, thiab polystyrene tawm tsam cov kev ua kom sov thiab kev laus Oxidattrative. Hauv kev lag luam roj hmab, nws txhim kho lub sijhawm ntev thiab kev ua tau zoo ntawm cov khoom siv hluavtaws hauv qab cua sov thiab oxygen kis. Nws kuj tseem siv rau cov roj nplua thiab roj los tiv thaiv oxidation uas ua rau viscosity nce, sludge tsim, thiab poob poob. Tsis tas li ntawd, nws yog siv nyob rau hauv cov nplaum, cov tshuaj pleev xim, thiab cov tshuaj tshwj xeeb uas muaj cov tshuaj ntev ua haujlwm ruaj khov yog qhov tseem ceeb.
Cov txiaj ntsig
Cov txiaj ntsig ntawm 4,4 - butylidenebis (6 {} butcility-teeb meem, thiab sib xyaw nrog ntau cov polymers thiab roj. Cov pab pawg thenhoyl phenroxyl ua raws li cov khoom noj hydrogen rau neutralize dawb radicals, yog li cuam tshuam cov kab mob oxidative oxiders. Lub TERCY TERT-Butyl thiab Methyl thiab Methyl Cov Lus Muab cov khoom ruaj khov, txhim kho thermal stability thiab tiv thaiv kom sai oxidation ntawm antioxidant nws tus kheej. Nws tus qauv Bifunctional ntxiv txhim kho kev ua haujlwm los ntawm kev muab ntau qhov chaw nquag hauv ib qho molecule, ua rau nws muaj txiaj ntsig zoo dua ntawm qis dua. Cov khoom no tshwm sim hauv lub neej kev pabcuam ntev dua, txo tus nqi txij nkawm, thiab txhim kho kev ua tau zoo ntawm cov ntaub ntawv thiab cov qauv.
Tag
Hauv cov ntsiab lus, 4,4 {- butylidenebis (6 {} Cov tshuaj tiv thaiv tertioxidant siv nyob rau hauv polymbers, rub, roj nplua nyeem, thiab hom tshwj xeeb. Nws cov ntawv thov suav nrog kev tiv thaiv oxidative kev ruaj khov, thaum nws tau txais txiaj ntsig kev pabcuam lub neej, thaum nws muaj kev pab cuam lub neej, thiab kev tiv thaiv standeristion, thiab ntau yam kev ua si. Raws li kev lag luam txuas ntxiv mus thov cov ntaub ntawv ruaj khov thiab ruaj khov, qhov sib xyaw ua ke tseem ceeb tshaj plaws rau kev ntseeg tau cov khoom lag luam kom ntseeg tau thiab ntev.
Cim npe nrov: 4,4 {- butylidenebis (6 {{} Tertylfenebis (6-Metylfelebis (6-Metylfphenol) muaj li 85-9-9 Cov Chaw Tsim Tshuaj, Chaw Tsim Tshuaj
