What problems can be avoided by adding water-based defoamers to coatings Different types of coatings are very effective in real life, especially in the decoration industry. However, in actual coating production, if some bubbles are not properly handled, it is very likely to affect the performance of the product. The following industry experts will give…
Precautions for using defoaming agent In the process of manufacturing foam ceramics and plastics in daily life, such as flotation, fire extinguishing, dust removal, washing, sometimes it is necessary to eliminate the bubbles generated in the manufacturing process. These bubbles are gas-intolerant and exist in industrial liquids or solids. They are substances that exist independently…
How to correctly determine the amount of different types of defoamers to be added For actual industrial production, different types of pharmaceutical products have outstanding effects, but if the correct use of the products is not mastered, it is difficult to exert the actual effects of the products. This is the case for defoamers. In…
Detection and use of silicone defoamers In the actual industrial production field, different types of defoamers are very frequently used pharmaceutical products, and to a certain extent, they are also the most powerful guarantee for the normal progress of industrial production. However, there are many types of defoamers in the field of industrial production, and…
Precautions for defoaming agents during floor construction Defoamer is the most common additive in epoxy flooring, which can accelerate the collapse of bubbles in flooring materials and prevent shrinkage and pinholes in epoxy floor coatings. However, the following points should be noted during use: 1. Fully stir: It is recommended that defoamer should not be…
Metalworking fluid defoamer function When the cutting fluid is used for metal processing, it will come into contact with a large amount of air and form excessive foam. The surfactant in the cutting fluid will form an adsorption film, which will stabilize the foam and affect the processing quality and precision. The reasons for the…
PVA special defoamer solves the foam crisis The Chinese name of polyvinyl alcohol is polyvinyl alcohol. After special treatment, it has unique strong adhesion, film flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier, wear resistance and water resistance. Therefore, in addition to being used as a fiber raw material, PVA is also widely…
Effect of ink defoamer The reasons for the foaming of ink printing are: 1. The pretreatment of the substrate is not good, that is, the substrate has not been cleaned before, so that its surface is full of dirt or oil stains. 2. Bubbles in the ink. This is mainly caused by improper ink formulation.…
