Characteristics and uses of silicone defoamers
Silicone defoamer is made of silicone grease, emulsifier, waterproofing agent, thickener and other materials with appropriate amount of water through mechanical emulsification. So what are the properties and characteristics of silicone defoamer? Let’s follow the defoamer manufacturer to learn about it.
Its characteristics are low surface tension, high surface activity, strong defoaming power, small dosage and low cost. It is immiscible with water and most organic matter, and can defoam most bubble media. It has good thermal stability and can be used in a wide temperature range of 5℃-150℃; it has good chemical stability and is difficult to react with other substances. As long as it is properly configured, it can be used in acid, alkali and salt solutions without damaging product quality; it also has physiological inertness LD250g/Kg mouse, and is usually used in food and pharmaceutical industries. It has both anti-foaming and defoaming functions for all bubble systems, and belongs to the category of broad-spectrum defoamer. It is widely used for defoaming in the production process of detergents, papermaking, pulp, sugar making, electroplating, fertilizers, additives, wastewater treatment, etc. In the petroleum industry, it is widely used for the desulfurization of natural gas and the acceleration of oil-gas separation; it is also used in the drying of ethylene glycol, the extraction of aromatic hydrocarbons, the processing of asphalt, the dewaxing of lubricating oil and other devices to control or inhibit bubbles. In the textile industry, it is used for defoaming in the processes of dyeing, refining, sizing, etc.; in the chemical industry, it is used for defoaming in the processes of synthetic resins, latex, coatings, inks, etc.; in the food industry, it is used for defoaming in various concentration, fermentation, and distillation processes. Silicone grease can be applied to the pot wall, the outlet, or the metal mesh for defoaming. Silicone grease can be prepared into a solution and used for defoaming in the oil phase system.
