Latex Paint Production Wastewater Demulsifier
Latex paint production wastewater is mainly produced when washing production equipment, paint cylinder, paint bucket, pipe and ground, mainly containing emulsion, emulsifier, additives, color paste, filler and other chemical substances. Emulsioni paint production wastewater COD concentration is high, high turbidity, chromatism, high suspended solids, difficult degradation, volatility, milk is very difficult, poor biochemical poor, difficult biodegradable substances and antibacterial effect of toxic substances, affect the normal activity in the process of biochemical treatment, it is difficult to handle standard, using emulsions paint wastewater can achieve good effect.
Latex Paint Production Wastewater Demulsifier can destroy the emulsifying liquid in the wastewater and separate it into two obvious layers of oil and water, so as to facilitate the subsequent treatment. On the one hand, the time efficiency is high, the time of weaning is fast, on the other hand, the effect is good, the liquid after weaning is clear, and the weaning is complete. It can also remove pollutants and decompose organic substances into relatively simple substances, thus reducing pollution emissions.
Demulsifier is a surfactant that reduces the surface tension of a liquid, allowing solid particles to be dispersed in water. There are two ends: a hydrophilic end and a hydrophobic end. Emultrastic molecules form a micelar structure in the water, the hydrophilic end towards the water and the hydrophobic end towards the particle surface, so that the solid particles are dispersed in the water.
Demulsifier is added to the wastewater of latex paint production, stir evenly, and observe its dispersion effect. The experimental results showed that the emulsion could make the particles disperse evenly, and the turbidity in the water decreased significantly.
