REVERSAL EMULSION DEFOAMER

摘要

PURPOSE: A reversal emulsion defoamer is provided, which has a viscosity of 200-400 cps at 25 deg.C and is excellent in water dispersibility and particle size distribution needed for a good defoaming force, so that the defoamer is easy and safety to use and can be used for wastewater treatment plants, dyeing process, paper-making process where a large amount of water is consumed. CONSTITUTION: The defoamer comprises 15-25 wt.% of C16-C30 long-chained fatty alcohol, 2-9 wt.% of C12-C40 alpha olefin, 1-5 wt.% of glycerol trioleate, 0.5-5 wt.% of polyoxy ethylene octyl phenyl ether, 65-75 wt.% of water and 0.02-0.1 wt.% of xanthan gum.
