Water based defoamer are a type of surfactant with high efficiency in defoaming and stabilizing foam. It can effectively reduce the surface tension of the liquid and form tiny aggregates in the liquid to prevent gas from escaping from the liquid to form bubbles. At the same time, defoamer can also be used as antifoaming agents to stabilize foam in situations where it is necessary to stabilize the foam.
1. Application fields of water based defoamer
Water based defoamer are widely used in the field of industrial manufacturing, especially in the fields of coatings, paper printing, inks, cleaning agents and pesticides, and play an irreplaceable role.
Coating field: In the coating manufacturing process, water based defoamer can effectively remove bubbles in the coating, making its coating more uniform, and the surface gloss and coating thickness more consistent.
Paper printing field: In the paper printing process, the use of water based defoamer can effectively eliminate bubbles on the surface of the ink and improve printing quality and output.
Ink field: In the ink manufacturing process, the addition of water based defoamer can effectively reduce the viscosity of the ink, improve printing quality, and reduce overprinting.
Cleaning agent field: In the manufacturing process of cleaning agents, water-based defoamer can reduce the surface tension of liquids, improve cleaning effects, and reduce cleaning costs.
Pesticide field: In the manufacturing process of pesticides, water based defoamer can effectively reduce the surface tension of liquids, accelerate the penetration of liquid medicines, improve drug efficacy, and reduce drug costs.
2. Types and selection of water based defoamer
According to different application scenarios and needs, water based defoamer can be divided into two categories: organic defoamer and inorganic defoamer. Organic defoamer have good stability and thermal stability, and are widely used for defoaming in harsh environments such as high temperature, high pressure, strong acid, and strong alkali; inorganic defoamer are mainly used for defoaming in low temperature and normal temperature environments, and have the characteristics of non-toxic, odorless, and pollution-free.
When choosing a water based defoamer, it is necessary to choose according to the different characteristics of the specific application scenario, and comprehensively consider factors such as surface tension, foam stability, high temperature resistance, applicable PH range, and cost.
Water based defoamer are an important chemical substance that is indispensable in industrial production and have efficient defoaming and foam stabilization effects. It has a wide range of applications, including coatings, paper printing, inks, cleaning agents, pesticides, etc. When using water-based defoamers, you need to choose according to actual needs and consider different factors comprehensively to achieve better results.
