PU

Leveling agent is a commonly used coating additive that can promote the formation of a flat, smooth, and uniform coating film during the drying process. A class of substances that can effectively reduce the surface tension of finishing fluids and improve their leveling and uniformity. It can improve the permeability of the finishing liquid, reduce the possibility of spots and stains during brushing, increase coverage, and make the film formation uniform and natural. Mainly surface active agents, organic solvents, etc.

From the physical point of view, the methods to eliminate foam mainly include placing baffle or filter screen, mechanical agitation, static electricity, freezing, heating, steam, radiation, high-speed centrifugation, pressure reduction, high-frequency vibration, instantaneous discharge and ultrasound (acoustic liquid control). These methods promote the gas transmission rate at both ends of the liquid film and the liquid discharge of the bubble film to varying degrees, making the stability factor of foam less than the attenuation factor, As a result, the number of foam gradually decreased. However, the common disadvantage of these methods is that their use is strongly restricted by environmental factors, and the Saint Lucia rate is not high. The advantages are environmental protection and high reuse rate.

Saint Lucia The chemical methods to eliminate foam mainly include chemical reaction method and adding Saint Lucia. The chemical reaction method refers to the chemical reaction between the foaming agent and the foaming agent by adding some reagents to generate water insoluble substances, thus reducing the concentration of surfactant in the liquid film and promoting the rupture of foam. However, this method has some shortcomings, such as the uncertainty of foaming agent composition and the harm of insoluble substances to system equipment. Nowadays, the widely used defoaming method in various industries is the method of adding defoaming agents. The advantages of this method are high foam breaking efficiency and convenient use, but finding suitable and efficient defoaming agents is the key.
