The function of the adhesive is to make it bond between two separated materials, and the water-based adhesive is one of the types of adhesives, mainly using water as a solvent, and has the characteristics of environmental protection, non-toxic, green and odorless, and is widely used in various industries, such as construction, home, packaging, textile and other industries. However, in the production and manufacturing process of water-based adhesive, the problem of foaming often occurs, and the appearance of bubbles will hinder the production and processing process of the adhesive and affect the quality of the water-based adhesiveDefoamer for water-based adhesivesto solve this production problem.
Application scenario diagram of water-based adhesive defoamer).
The main reasons for the foam of water-based adhesive defoamer are as follows: in the production process of water-based adhesive, surface-active substances such as dispersants, wetting agents, etc. are added, and if the surface active substances are added excessively, the surface tension of the water-based adhesive will be changed, so it is easier to form stable bubbles. In addition, high-speed mixing equipment is used in the production process, and a large amount of air is swept into the adhesive during rapid stirring, which is difficult to overflow and becomes foam. When water-based adhesives are stored and used, the temperature and humidity of the environment are factors that affect the formation of bubbles in the adhesive.
The bubbles produced by water-based adhesives will bring a series of hazards, and the foaming of water-based adhesives will increase the volume of the product, so that the net content of the barreled product is not enough, on the one hand, it will increase the packaging cost, and on the other hand, it will reduce the trust of customers. In addition, water-based adhesives create bubbles, and gas foam can hinder production operations and result in uneven dispersion of fillers. In addition, foaming will endanger the quality of water-based adhesives, reduce the viscosity of adhesives, and easily cause the phenomenon of adhesive materials falling off.
Defoamer for water-based adhesivesIt is suitable for the manufacturing process of various adhesives, and is used as a defoamer for adhesive systems, which has the characteristics of easy dispersion and easy use. It has defoaming effect and antifoam function in a wide pH and temperature range, which can quickly eliminate foam and has the effect of preventing foam**. It is a defoamer that has both long defoaming and good foam inhibition, strong foam reduction ability, long foam inhibition, no needle hole and no impact on product firmness.
