White latex is constantly innovating in technology and application. Some new types of white latex products have emerged, with better adhesion properties, shorter drying time and a wider range of applications, and at the same time in order to solve the foam problemWhite latex defoamerThe addition of the link became an indispensable part.
First, the cause of blistering.
During the application of white latex, the main causes of foam are as follows:
1.Stirring: When white latex is stirred, mechanical force introduces gas into the colloid, resulting in bubbles.
2.Gas solubility: The presence of certain materials or additives, such as surfactants, solvents, etc., can increase the solubility of the gas in the colloid, resulting in the formation of foam when the gas is released.
3.Reaction process: Certain chemical reaction processes in white latex can also produce gases that lead to the formation and accumulation of foam.
Second, the role of defoamer.
Latex defoamerIt is a substance that can effectively destroy and inhibit the formation of foam, and has the following effects:
1.Destruction of foam structure: Defoamers have the ability to destroy foam structure. Foam is made up of bubbles, and the defoamer is able to diffuse rapidly into the foam, reducing the surface tension, causing the foam structure to burst and the bubbles to be released quickly.
2.Improve product quality: The foam in white latex can affect product quality, such as reducing bond strength and affecting coating flatness. By using defoamers, the presence of foam can be effectively reduced and the quality and performance of the product can be improved.
3.Increased production efficiency: The creation of foam in white latex increases process complexity in the production process and can lead to stagnation and failures in the production process. By using defoamers, you can reduce the interference of foam, improve production efficiency and reduce production costs.
