Cov khoom siv
1.Tert-Butylhydroquinone yog cov tshuaj tiv thaiv kab mob antioxidant. Hauv cov khoom noj, tert-butylhydroquinone yog siv los ua cov tshuaj tua kab mob rau cov roj zaub thiab ntau yam tsiaj noj rog.
2.Hauv kev tsim khoom, tert-butyl hydroquinone tuaj yeem siv los ua tus stabilizer los tiv thaiv tus kheej-polymerization ntawm cov organic peroxides.
3.TBHQ tuaj yeem siv los ua ib qho fixative, inhibiting volatilization thiab txhim kho stability. Tsis tas li ntawd, nws kuj yog siv nyob rau hauv cov xim, varnishes thiab resins.
4.TBHQ yog ib qho kev nyab xeeb thiab siv tau cov roj antioxidant, haum rau cov roj zaub, lard, thiab lwm yam. Tshwj xeeb tshaj yog tsim rau cov khoom noj kib vim nws qhov siab melting point thiab boiling point.
Ntim Thiab Cia
