Application of water-based floor paint defoamer

Application of water-based floor paint defoamer

1. The working principle of antifoam agent

Antifoam agent is a chemical additive designed to reduce and hinder the formation of foam. Its core ingredient significantly reduces the tension on the surface of the liquid, which destabilizes the foam and makes it easy to burst or dissipate. Specifically, the active ingredient in the defoamer rapidly penetrates the foam film, reducing its surface tension and causing the foam film to thin out and burst. At the same time, the defoamer can also form a bridge between the foam film, so that the connection between the foam becomes unstable, to eliminate the purpose of the foam.

2.the application characteristics of water-based floor paint defoamer

Water-based floor paint defoamer has the characteristics of low dosage, fast foam elimination and long foam suppression. It not only can effectively eliminate microfoam, but also has strong water solubility, the use of film will not affect the film, there will be no shrinkage, fish-eye and other problems. In addition, water-based floor paint defoamer has good compatibility with water-based paint, to ensure the smooth progress of painting.

3.the use of water-based floor paint defoamer

The use of water-based floor paint defoamer is relatively simple. Can be added directly to the foaming system, such as in the mixing of paint when adding a certain amount of antifoaming agent. In order to achieve the effect of lasting foam suppression, it can also be added in batches. In practice, it is usually recommended to add defoamer at the stage of high viscosity of the paint, such as grinding and paint mixing stage, to ensure that it can be well dispersed, to avoid undesirable phenomena such as sedimentation or fish-eye.

4.the importance of water-based floor paint defoamer

Eliminate paint foam: in the water-based paint coating process, due to stirring, pumping and other reasons, the paint surface often produces a large number of bubbles. These bubbles not only affect the beauty of the paint surface, but also may lead to a decline in coating quality. The use of water-based floor paint defoamer can effectively eliminate the paint surface foam, to ensure the quality of the coating.

Improve painting efficiency: the existence of foam will reduce the efficiency of painting, because the foam will occupy the space of painting equipment, reducing the actual amount of painting. By using water-based floor paint defoamer, the foam can be reduced, thus improving the efficiency of painting.

Reduce painting cost: Foam may lead to the waste of paint and increase the painting cost. The use of water-based floor paint defoamer can reduce the waste of paint, thus reducing the cost of painting.

5.the choice of water-based floor paint defoamer precautions

Defoaming effect: in the choice of water-based floor paint defoamer, the first thing to consider its defoaming effect. You can test or check the product description to understand its defoaming performance, to ensure that the selected product can meet the needs of painting.

Compatibility: water-based floor paint defoamer should have good compatibility with the water-based paint used to avoid precipitation, delamination and other phenomena.

Safety: It should be ensured that the selected products are safe and harmless to the environment and human body, and comply with relevant regulations and standards.

Economy: When choosing, you also need to consider the price factor, choose cost-effective products to avoid poor quality and affect the painting effect.
