Choosing the right emulsifieris crucial. It not only promotes emulsion formation, facilitating the formation of fine particles and improving emulsion stability, but also allows for control over the type of emulsion. 1. General principles for selecting emulsifiers Due to the…
1.Surface tension The contraction force of any unit length of the liquid surface is called surface tension, and the unit is N•m-1.2.Surfactants and surfactants The properties that can reduce the surface tension of solvents are called surfactants, and substances with…
Defoamer is a class of chemical substances used to reduce or eliminate foam, widely used in food, pharmaceutical, petroleum, chemical, paper, paint, textile and other industries. In this paper, the classification, mechanism of action, application field, influencing factors and research…
Defoamer in water treatment is a chemical used to control or prevent the formation of bubbles in water. The defoamer mainly reduces the dispersion of the gas in the liquid by destroying the surface tension of the liquid, thereby preventing…
Introduction: During oil field production, the mixture of gases and liquids often forms foam, which can affect production efficiency and operational stability. To solve this problem, oil field defoamer is widely used as a chemical additive designed to reduce the…
A demulsifier is a chemical used primarily to separate and purify emulsions, but can also be used to break up emulsifying systems. Demulsifier is an indispensable and important industrial auxiliary agent in petroleum, chemical industry and dairy industry. This paper…
During oil field development, many people often encounter foaming problems. The causes of these foams are diverse. The addition of surfactants in oilfield development aids easily leads to foam formation. The mixing of a large amount of air during equipment…
