Read about paint defoamer in one article In addition to being beautiful, paint also forms a strong solid film, which is a protective coating. However, it often encounters a problem, that is, foam. Water-based paints and solvent-based paints use various additives in the formula, such as wetting dispersants to make pigments and fillers easy to…
Drilling fluid bubbles and defoaming 1. Causes of Drilling Fluid Foaming Drill into the air layer. Gas in the formation invades the drilling fluid, causing the drilling fluid to foam. Drilling fluid materials contain foaming materials such as surfactants, which are added to the drilling fluid to cause the drilling fluid to foam. 2.The hazards…
Analysis of the causes of turbidity in defoaming agents The main components of defoaming agents are generally hydrophobic particles + silicone oil + emulsifier. Hydrophobic particles adsorb silicone oil, allowing the silicone to achieve the maximum effect with as little silicone as possible. Silicone oil, the main defoaming medium, has very small surface tension and…
Principles of bubble formation and bursting In water-based coating systems, the introduction and stabilization of hydrophobic substances such as emulsion molecules, pigments and fillers into the water-based system is achieved through surface-active substances. The emulsifier ensures the stability of the emulsion resin molecules in the aqueous phase, and the pigments and fillers can be mixed…
Choosing the wrong defoamer can lead to endless troubles Many customers are dazzled by the wide variety of products when choosing defoaming agents. After a simple sample, they choose the wrong defoaming agent, which has a great impact on production and operation. The consequences of this are summarized below: 01 Affect product appearance After choosing…
Are defoaming agents considered hazardous waste? Defoaming agents, also known as defoaming agents (anti-foaming agents), are commonly used in: textile industry, petrochemical industry, emulsion processing, surfactants, metal cleaning industry, wastewater treatment, chemical industry, detergents, water treatment, etc. and other industries that require anti-foam treatment. As long as the defoamer produced by a regular manufacturer is…
Dilution method of defoaming agent Defoaming agent is an auxiliary agent whose function is to eliminate foam formed by materials during the production process. Silicone defoamer is a white, viscous emulsion. In chemical, paper, coating, food, textile, pharmaceutical and other industrial sectors, silicone defoamer is an indispensable additive in the production process. It can not…
The defoaming agent is so powerful, if you don’t believe it, take a look! 01 Foam refers to a dispersion of air, carbon dioxide and other gases dispersed in water, oil, slurry, dyeing liquid and other liquids. There are two aggregation states of foam, one is dilute foam, the interaction between bubbles is weak and…
