Product Description

Product description:

China's alumina production process mainly includes Bayer method, sintering method and sintering - Bayer combined method, mainly Bayer method. In the process of production, a large number of compound organic foams will be produced in the desiliconization, red mud settling and seed decomposition sections. The main foam problem is concentrated in the seed decomposition section, because the system contains a large number of organic matter, solid impurity particles, aluminum hydroxide particles, so that the foam structure is stable, so that the foam continues to accumulate, and even overflow phenomenon. The formed foam layer covers the liquid level in the tank, which also makes it difficult for the gas to escape from the system. Foam overflow will cause environmental pollution, too much foam will also affect the seed decomposition efficiency, reduce the life of the pump. Therefore, it is necessary to use defoamer to eliminate and control foam.



Alumina Defoamer AFV-8020:

AFV-8020 is a special alumina defoamer developed for foam control in the process of bauxite smelting. The main component of this product is polyether polyol, with excellent dispersion performance, which can effectively eliminate and inhibit the red mud settlement, seed decomposition, and foam in the working fluid of the training and burning section. This product has no effect on the seed decomposition efficiency and will not cause any adverse effect on the quality of the finished alumina.

Performance parameters:

Excellent foam inhibition performance | wide applicability | has no effect on seed decomposition process


Adding method: 

Continuous addition: The use of electromagnetic diaphragm pump will be the antifoam agent in accordance with the specified flow point, quantitative continuous addition.


Volume of addition:

The recommended addition amount of ores with high organic content is 15-25ppm;
It is recommended to add 5-15ppm of ore with low organic matter content;
When the foam is small, it is recommended to maintain the addition amount of 2-5ppm to prevent the emergence of the bubble outbreak.
According to the different components of the ore, the foaming capacity of the system will be significantly different, and it needs to be adjusted according to the actual situation on site.
