Classification of defoaming agents There are many kinds of defoaming agents, which have the characteristics of breaking foam and having strong diffusion effect. Their main categories are introduced below: 1. Alkali-resistant defoaming agent. This kind of defoaming agent can quickly defoaming, long-lasting foam suppression, good stability, low dosage, high efficiency, and does not bleach oil.…
Be careful when using defoaming agents The amount of defoaming agent must be strictly controlled when used, and it is not allowed to be added without permission. Select the appropriate amount according to actual needs. The specific application method is as follows: 1. Application in coatings. Improper use of defoaming agents in coatings can cause…
The use of defoaming agents in dyeing and finishing In the printing and dyeing of knitted fabrics, bubbling will cause the fabric to float on the water. In severe cases, undesirable phenomena such as cloth blocking may occur. So what about the use of defoaming agents in dyeing and finishing? 1. Technical characteristics Defoaming agents…
The main characteristics of organic defoaming agents Silicone defoaming agents have incomparable advantages over traditional defoaming agents. Even when used in a small amount, they can achieve strong foam-breaking and foam-suppressing effects. Its main features are as follows: 1. Low surface tension. The surface tension is lower than water, surfactant aqueous solutions and general oils,…
Specific applications of silicone defoaming agents for pesticides During the processing and use of pesticide preparations, when pesticide emulsions, suspensions and other liquids containing surfactants are stirred, shaken or impacted, foam can easily occur. These foams contain toxic substances, so adding silicone defoamer can eliminate them. The main applications of bubbles are as follows: 1.…
Analysis of defoaming process of silicone defoamer Nowadays, when treating sewage, silicone defoamer is generally used, and the effect is good. So what is the defoaming process of silicone defoamer? 1. General process When a silicone defoaming agent is added to the foam, it will disperse quickly, and the active agent molecules will be oriented…
Types of silicone defoamer Silicone defoamer is also a type of defoamer. It also has the functions of foam breaking, foam suppression and defoaming. Its main categories are as follows: 1. Defoaming agent for oil systems. The silicone oil is carried by a solvent and dispersed into the primer fluid. The solvent diffuses, and the…
Functional performance of defoaming agents We all know that the main function of defoaming agents is to defoam, mainly to eliminate harmful substances in the foam. Let’s take a look at its performance: 1. The defoaming effect is obvious. It can change the surface tension of the foam, causing small bubbles to gather into large…
