3. Cov nplaum thiab xov xwm
Txhim kho covOkidative thiab thermal ruaj khovNtawm kub yaj cov nplaum thiab cov txheej txheem foob, tshwj xeeb tshaj yog nyob rau qhov chaw kub lossis nce qib lossis ntev.
4. Lubricts thiab Greases
Ua raws li antioxidant nyob rau hauvKev lag luam khoom lag luam thiab siv hluav taws xob hauv tsheb, qhov twg nws ua rau kev tsim ntawm sludge thiab cov kua roj sternish los ntawm oxidative deg.
5. Cov txheej txheem thiab cov resins
Ingorated rau hauv Epoxy thiab Alkyd Resin Systems los txhim kho cov laus tsis kam thiab xim khaws cia thaum kho thiab kev pabcuam.
Cov txiaj ntsig thiab cov yam ntxwv
Siab thermal ruaj khov: Muaj txiaj ntsig txawm tias ntawm kev txhawb nqa thiab pabcuam kub.
Tsis-discoloring: Tswj hwm cov duab kos duab thiab xim ruaj khov nyob rau hauv cov xim muaj xim.
Tsis tshua muaj volatility: Haum rau kev ntsuas kub siab.
Synergistic tus cwj pwm: Tuaj yeem siv ua ke nrogPhosphite lossis Thioft antioxidantsrau kev tiv thaiv kev tiv thaiv.
