Impressive! Defoamer & Antifoam have such a wide range of applications.
Defoamers are chemical products designed to prevent foam formation, disrupt foam stability, and achieve rapid defoaming. They work by diffusing into the gas-liquid interface, wetting the foam, thinning the local liquid film, and causing the entire foam to collapse, thereby achieving the defoaming effect. So, in which fields can defoamers and antifoams be applied?
PAPER INDUSTRY
Wheat straw, rice straw, pine wood, waste paper, bamboo, and other materials in paper pulp, along with surfactants, readily generate foam. Adding defoamers during pulping, pulp washing, and black liquor treatment effectively controls pulp overflow and improves paper quality.
Water Treatment
Various wastewater treatment systems and industrial water systems may generate foam due to impurities in the liquid. Defoamers can rapidly eliminate foam produced by sludge, water treatment chemicals, biocides, and other agents. They prevent clogging of circulation water treatment systems, ensuring optimal system performance.
Metal Cleaning Industry
Defoamers and antifoams are suitable for degreasers, metalworking fluids, cutting fluids, pretreatment cleaners (for pickling and phosphating processes), spray plating cleaners, degreasers, metal wire drawing fluids, fluxing agents, machine wiping fluids, etching solutions, steel plate cleaners, electroplating, and chemical immersion cleaning products.
Oil drilling
During petroleum drilling operations, when encountering gas-bearing formations, hydrocarbons, CO₂, H₂, S₂, and other gases within the formation diffuse or infiltrate into the drilling fluid. The circulating drilling fluid acts as a mixing agent that promotes bubble formation. Additionally, drilling fluid additives typically possess surface-active properties, making drilling fluid prone to foaming. Foaming in drilling fluid can adversely affect drilling operations in numerous ways. In such cases, defoamers are required to eliminate bubbles within the drilling fluid, thereby enhancing drilling efficiency and quality.
Power Plant Desulfurization
In power plant desulfurization equipment, the slurry continuously absorbs harmful substances from flue gas. The surfactants and dust within it, along with impurities such as heavy metal ions present in the power plant, cause an increase in the difference between the surface tension of the surface and the inner layer solution. Consequently, when air enters the solution, foam forms. To achieve better desulfurization results, power plants add defoamers to the desulfurization tower. These defoamers help the system improve desulfurization efficiency.
