Alumina seed decomposition defoamer factory supply best price
Bauxite is mainly hydroduralumite, this ore has a high silicon content, and in order to improve the content of alumina, flotation agents are generally added in the flotation process, resulting in a large amount of organic matter enrichment, which has surface active substances, will cause the decomposition slurry in the decomposition process a large number of bubbles, thus seriously affecting the yield and quality of alumina. Therefore, the addition of alumina defoamer in the decomposition section has become an essential link in the production process.
If the Bayer method is used to produce alumina in the factory, there will be a large number of bubbles in the ore slurry, so that the decomposition rate of sodium aluminate solution is low, weaken the efficiency of the evaporator, resulting in an increase in the content of sodium carbonate in the solution, reduce the flow of materials, and affect the coordination of the production unit. Because the aluminum alkali solution in the production process of alumina has a strong alkalinity and a high temperature, the defoamer selected should have chemical stability and non-volatile to the strong alkaline medium.

This product has good continuous bubble inhibition, High degassing efficiency, a full benefit.
1. The amount is small, the solid content is high, the defoaming speed is fast, in the decomposed alumina solution, only a small amount of defoaming agent is needed, and the defoaming time is less than 10 seconds.
2.The chemical properties are stable, not easy to react with organic matter, but not with the industrial production cycle and a large amount of consumption, can save a lot of energy.
3.Has a good anti-foaming effect, and under the premise of not reducing the decomposition rate, there is basically no effect on the product decomposition rate and quality, but also effectively improve the quality of alumina products, bauxite dissolution, red mud settling array, aluminate solution decomposition, mother liquid evaporation and other processes have no adverse effects.
4.In the alumina production process of concentrated aluminum alkali solution, hydrolysis will not occur, long-term contact will not affect their bubble inhibition. Moreover, while defoamer is defoamer, it will also improve the purity of the overflow liquid during the separation of red mud, increase the decomposition half of aluminate solution by 0.6%~3.1%, increase the sedimentation rate of pulp by 0.6~5.5 times, and accelerate the evaporation of mother liquor by 3%~10%.
