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-8030:
This product is polyether defoamer, which is a special defoamer for aluminum oxide developed for foam control in bauxite smelting process. It can effectively eliminate and inhibit the foam in the working solution of red mud sedimentation, seed crystal decomposition and roasting sections. This product has no impact on the efficiency of seed crystal decomposition and will not have any adverse effects on the quality of finished alumina products.
Performance parameters:
Product features:
Excellent foam suppression capability| Excellent anti-attenuation performance | It can be applied to different mining conditions
Application:
Foam removal and suppression in seed decomposition section
Foam removal and suppression in red mud settling section
Foam removal and suppression in the roasting section
Adding method:
Adding method: Add raw liquid, use flow pump for continuous addition
Adding point: Group up tank head tank
Adding quantity: It is recommended to use 10-15ppm. In case of little foam, it is still recommended to use 3-5 ppm to prevent foam from bursting
