Seeing the water-based glue defoamer, the foam burst into tears

The application range of water-based glue is very wide, not only in people's daily life, but also in industrial production can see its shadow. However, there is a very common problem in the production and use of water-based glue, that is, the problem of foaming.

First of all, explain to you where the foam in the water-based glue comes from.

1. In order to improve the performance of the glue, each manufacturer usually adds a certain amount of chemical additives or additives to help improve the viscosity, most of these additives are surfactants, which contain substances that are easy to foam;

2. Due to the vibration and stirring of machinery and equipment, the foam is generated;

3. Due to the viscosity of the glue or the improper mixing method in the process of glue, it is easy to produce foam;

4. The air humidity and temperature of the operating environment do not meet the requirements of the production glue, resulting in foaming.

Due to the above problems of glue, it is often difficult to be completely eliminated, if the problem of water-based glue bubbles is not solved, the existence of these foams will lead to a decrease in the viscosity of water-based glue, affecting the quality of the product; it will also lead to operational difficulties in the production process, and the air in the foam will hinder the dispersion of the filler; stable foam will also deepen the volume of the barrel, so that the weight of the barrel is uneven, increasing the cost of packaging; it may even lead to a reduction in the life of the machine and equipment, which may cause a certain degree of environmental pollution. Therefore, it is urgent to rectify the problem of water-based glue foam.

What are the characteristics and advantages of water-based glue defoamers?

1. The water-based glue defoamer is refined by a special process of modified polyether silicon, which has good thermal stability and chemical stability, and can form a stable unbalanced surface tension in the foam and control the foam;

2. The addition of water-based glue defoamer will not affect the quality and performance of glue, easy to disperse in the aqueous system, strong defoaming ability, long foam suppression time, can be soluble with various types of processing fluids, will not be layered bleaching oil, can effectively eliminate the foam in the glue;

3. It has strong adaptability, stable chemical properties, good leveling performance, and does not affect its antifoam and defoaming properties in the environment of high temperature and strong acid and alkali;

4. Widely used, not only to solve the foaming problem of water-based glue, but also suitable for adhesive manufacturing, adhesives, adhesives, acrylic emulsion, white latex, polyvinyl alcohol glue and other emulsions.
