Application Areas
Paper Industry
During the papermaking process, a large amount of stable foam will be generated in the process of raw material cooking, pulp transportation, coating application, etc., resulting in: holes, spots, and fish eyes on the paper surface, affecting smoothness and printability;
The dehydration efficiency of the wire section decreases, and the frequency of paper breaks increases.
Dosing point
Pulping section: pulp washer outlet or black liquor tank top;
Papermaking section: white water pool under the net or pulp pump inlet;
Coating section: coating storage tank or before the feeding pump.

Water treatment industry
In the process of water treatment, the foam generation varies depending on the types of domestic drainage and industrial drainage. In addition, there are a large number of various substances. Therefore, it is necessary to select a suitable defoaming agent to solve the foam problem in the water treatment process.

Oil Industry
Foam will be generated during the processes of oil refining, oil extraction, and transportation. The generation of foam will reduce work efficiency and have adverse effects on products. Choosing a suitable defoaming agent will bring you different beneficial effects.

Textile printing and dyeing industry
In the processes of sizing, oiling, scouring, dyeing, printing and finishing of synthetic fibers, the production materials such as surfactants, detergents and adhesives will become foaming liquids and generate a large amount of foam, which will cause various failures. Therefore, defoamers are needed to effectively eliminate the foam that causes production failures.
Architectural coatings industry
With the development of science and technology, in order to improve the product quality of coatings and bring higher benefits, various additives are used in coating formulas. Most of these additives are surfactants, which can change the surface tension of the coating, making the coating itself contain inherent factors that are easy to foam or stabilize the foam. In addition, the shear force in the coating production process causes foam to be generated, resulting in production operation difficulties, insufficient equipment utilization, uneven surface and other problems. Therefore, defoaming agents need to be added in the coating production process.
Building materials defoamer
Concrete, mortar, putty, gypsum, self-leveling, ceramic glaze. All stubborn bubbles that emerge during the mixing, pumping and coating of building materials can be quickly broken by building material defoamers and the foam can be suppressed for a long time, making the finished product denser, the surface smoother and the strength more reliable..
Adhesive defoamer
Adhesive defoamer is a functional additive specially used to eliminate and inhibit the generation of foam during the production, mixing, coating or curing process of adhesives (including water-based, solvent-based, solvent-free and other systems).
Paint defoamer
Foam can cause defects such as pinholes, shrinkage cavities, and fish eyes in the paint film, which seriously affect the aesthetics, protection and adhesion of the coating. Paint defoamers are functional additives specifically used to eliminate harmful foam generated during the production, construction and drying of paint.
Surface cleaning industry
When cleaning the surface, the cleaning chemicals used contain a certain amount of surfactants. Some industries have a certain amount of pressure during surface treatment, and a large amount of foam will be generated during the cleaning process, which seriously affects production efficiency and requires the use of defoaming agents to solve the problem when cleaning the surface.
Cutting fluid defoamer
A special additive for the "foaming" problem of metalworking fluids. Just a little addition can quickly break up bubbles and permanently suppress them, allowing coolants and lubricants to restore their optimal performance.
Circuit plate cleaning defoamer
Specially designed for PCB development, film stripping, water washing, ultrasonic and spray cleaning, adding 0.05-0.3% can instantly eliminate stubborn foam, without silicon spots or residues, ensuring fine circuits without bridges
Detergent defoamer
Detergent defoamers are chemical additives designed to suppress and eliminate the foam generated during the production and use of detergents. Although detergents usually require a certain amount of foam to improve the user experience, excessive foam will reduce cleaning efficiency, increase rinsing difficulty, and even damage equipment (such as industrial washing machines and dishwashers).
Chemical Industry
In the production process of synthetic resins, latex, adhesives and other products, foam will be generated during the mixing, reaction, distillation, cleaning and recycling of raw materials, which will affect production efficiency, product quality and other aspects. Therefore, defoaming agents are needed to eliminate the generated foam.
Metal cleaning defoamer
A special additive for the "foaming" problem of metalworking fluids. Just a little addition can quickly break up bubbles and permanently suppress them, allowing coolants and lubricants to restore their optimal performance.
Desulfurizing defoamer for power plant
Foam can lead to reduced desulfurization efficiency, equipment corrosion and even system shutdown, which is a key pain point in the desulfurization process of coal-fired power plants. Power plant desulfurization defoamer is a functional chemical specially used to inhibit the generation of foam in the absorber slurry in the wet flue gas desulfurization system (WFGD).
Industrial cleaning defoamer
Industrial cleaning scenarios are complex (such as high temperature and strong alkali, high pressure spray, and high solid content systems). Foam will reduce cleaning efficiency, increase energy consumption, and even cause equipment damage. Industrial cleaning defoamers are chemical additives designed specifically to eliminate harmful foam generated during various industrial cleaning processes.
