Application characteristics of defoaming agents Defoaming agents are substances used to reduce surface tension and eliminate foam during food processing. Then its application performance is mainly as follows: 1. Practical application of eliminating bubbles. The generation of foam is mostly caused by the surface active substances contained in the solution forming bubbles and floating at…
The impact of defoaming agents on papermaking Foam generally appears in paper pulp, which is very annoying and hinders the effective operation of the equipment. So what is the impact of defoaming agents on papermaking? 1. Great influence Foam has a great impact on the papermaking process. Foam appears in the paper stock, causing fluctuations…
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…
