Field of technology:

The technology of this product belongs to the unshaped refractory castable technology field, in particular to an albescent enhanced separant for suppression of unshaped refractory castable and its production method.

 

Background technology:

At present, the unshaped refractory castable often has white fuzz on the surface after the film is removed, which often happens in the summer. The unshaped refractory castable will fall off layer by layer if measures are not adopted in a timely manner. Strength indicators will decline and the unshaped refractory castable will even be broken completely. In view of this phenomenon, it is necessary to develop a special treatment preparation or treatment method.

 

Content of this product:

In order to overcome these technical problems, an albescent enhanced separant for suppression of unshaped refractory castable is provided, which is easy to use and can be sprayed on the surface of the castable which has white fuzz. In addition, the preparation method for this albescent enhanced separant for suppression of unshaped refractory castable is provided. The enhanced separant made through this method can be stored for a long time and can be directly used without using any aids.

 

Technical program:

This enhanced separant is sprayed on the surface of the unshaped refractory castable. A layer of protection film will be naturally formed after it is dried. In this way, the alkali (including potassium and sodium salts) in the refractory castable will not act with the carbon dioxide in the air and the white fuzz will not happen. In addition, during the use in the high temperature, the enhanced separant on the surface will form a kind of “glaze” on the surface of the lining of the castable with the rising of the temperature, which effectively improves the refractoriness and abrasion resistance of the unshaped refractory castable.

Brief description of the drawings:

Production method:

Add the alumina powder and aluminum hydroxide into the weighed water and heat the mixed solution to boiling. Add the weighed sulfuric acid solution having a mass concentration of 85% and sulfuric acid solution having a mass concentration of 50% and the oxalic acid inhibitor into this boiling solution and keep the boiling state for 30 min. The albescent enhanced separant for suppression of unshaped refractory castable is made after it become cool.

 

The method of usage:

This albescent enhanced separant for suppression of unshaped refractory castable is sprayed on the surface of the unshaped refractory castable. A layer of protection film will be naturally formed after it is dried. In this way, the alkali (including potassium and sodium salts) in the refractory castable will not act with the carbon dioxide in the air and the white fuzz will not happen. In addition, during the use in the high temperature, the enhanced separant on the surface will form a kind of “glaze” on the surface of the lining of the castable with the rising of the temperature, which effectively improves the refractoriness and abrasion resistance of the unshaped refractory castable.
