Vivid anti-foaming agent is made from mono- and diglycerides, silicone emulsion, calcium carbonate and phospholipids. Silicone-based defoamer has small surface tention, high surface activity, and strong defoaiming ability with low dosage as well as low cost. It is immiscible with water and most organic medium matter, so that it can eliminate most bubble mediums. Due to heat stability, it can be used in a wide temperature range of -5 ℃ ~ -150 ℃ ; due to chemical stability, it can be used in acid, alkali and salt solution with no damage to product quality if the formula is appropriate.
