Leveling agents are generally divided into two categories. One type of leveling agent works by adjusting the viscosity and leveling time of the paint film. Most of these leveling agents are organic solvents or mixtures with high boiling points, such as isophorone, diacetone alcohol, Solvesso 150, etc; The other is to adjust the surface properties of the paint film to play a role, and generally speaking, leveling agents refer to this type of leveling agent. This type of leveling agent migrates to the surface of the paint film through limited compatibility, affecting surface properties such as interfacial tension of the paint film, and achieving good leveling of the paint film. Depending on the chemical structure, there are three main types of leveling agents: acrylic acids, organosilicon, and fluorocarbon compounds
hardening
SwedenWhen choosing paint defoamer for aquaculture wastewater treatment, let's first see what kind of foam in wastewater belongs to, which is usually divided into chemical foam and biological foam. Chemical foam is also divided into active agent foam and oil and suspended solids foam. Active agent foam: when detergent, colloidal organic matter and other surfactants or other foaming substances are present in the sewage, under the conditions of water flow speed, fall, aeration, blowing off, etc., a large number of small and light white brown unstable foam will appear on the water surface. This kind of wastewater is a high molecular synthetic substance with poor biodegradability, which is a problem in sewage treatment. Biological foam: It is generally earthy brown or grayish brown, and there are many reasons for this kind of foam, so it is difficult to deal with. With the defoamer for aquaculture wastewater treatment, it is not necessary to consider whether it is suitable or not. This defoamer has strong versatility and can adsorb surfactants and change the hydrophilicity of surface activity. After dilution and regulation, it can enter biochemical treatment, which can solve the problem of chemical foam or biological foam.How much is it
dispersant
Sweden The antifoaming agent for aquaculture wastewater treatment is paint defoamerfor the aquaculture wastewater industry system. It can quickly disperse in water, is easily soluble in water, is not easy to break emulsion and float oil, and is fast in paint defoamer and long in inhibiting foam. It does not change the oxygen content of water quality or the microorganisms in the water, and has good acid and alkaline resistance, wide application range, and good chemical stability.
