Water-soluble defoamer can be called a half pillar in the big family of defoamer. It is more popular than other types of defoamer in all walks of life, especially for foam treatment of industrial products. This is mainly related to its effect performance. It not only has fast defoaming speed and long-lasting foam suppression, but more importantly, it will not cause product shrinkage and corns when dealing with foam in water-based coatings, inks, inks and other processes. It is of great help to PCB, paint coatings and other industries.
Application of water-soluble defoamer
Why are water-soluble defoamer widely used:
It is a defoamer in liquid form, which is produced by introducing modern technology through a special process. The composition is very complex, and its main components include: polydimethylsiloxane, polyoxypropylene glycerol ether, and aliphatic amide. It has good diffusivity, permeability, chemical stability, and strong oxidation resistance. Compared with general defoamer, its comprehensive performance is relatively stable, and there will be no stratification, demulsification and some other adverse reactions. This is also in the industry. The reason it is more popular in production foam processing.
Precautions for the use of water-soluble defoamer:
It is recommended to use pH test paper when the defoamer is diluted to adjust the pH value. The overall pH value after dilution must be carefully controlled, because the pH value of the entire system and the later use effect will be affected by the pH value at this time. Use pH test paper , you can control the pH value more accurately.
When diluting, it is best not to use hot water, because this defoamer is an emulsion type defoamer. Hot water will lead to poor stability of the defoamer, and poor control will cause stratification, demulsification, and precipitation. . It is recommended to use a thickener, and if there is no cleavage, only cold water can be used. After the release, it should be prepared and used immediately, because the application period of the defoamer is only 2-4 hours, so it is necessary to determine the dosage and time, and do the test first to avoid waste.
