What are the characteristics of rare earth special defoamers?

　　Do you know what rare earth is? Rare earth is the general name of 17 metal elements including lanthanide, scandium and yttrium. It is known as "gold" in industry and can be used in industry, agriculture and military. People often extract various mineral elements from rare earth, but rare earth often produces foam when extracting other elements. Therefore, according to the characteristics of rare earth foaming, someone invented a special rare earth defoamer to solve the foaming problem.

　　What is the reason for the foam of rare earth?

　　1. When rare earth is extracting other mineral elements, there are many foaming substances in them. The foaming ability of these foaming substances is enhanced, resulting in the increase of foam.

　　2. Strong mechanical impact and stirring will also produce foam.

　　3. Other chemical additives need to be added when preparing other minerals. These chemical additives will destroy the molecular structure during operation, cause chemical instability and destroy the chemical equilibrium state, resulting in the generation of bubbles.

　　The bubbles will seriously affect the extraction effect, resulting in a series of adverse effects, such as the reduction of extraction rate, landform restoration and environmental damage.

　　Characteristics of special defoamer for rare earth: the special defoamer for rare earth is composed of polydimethylsilicone oil, dispersant, emulsifier, etc., which can maintain good defoaming and foam inhibition effect at low concentration. It has strong adaptability and wide pH value, and can quickly defoaming and inhibit foam for a long time. It can be used for harsh chemical cleaning and chemical reaction with high temperature and high acidity. The addition amount is usually 0.1%~0.3% of the total volume.
