Method for preparing basic magnesium borate whiskers by using bitter halogen of salt lakes

Abstract

The invention discloses a method for preparing basic magnesium borate whiskers by using bitter halogen of salt lakes. The method includes the following steps: step S1: a plurality of groups of experimental data of basic magnesium borate whiskers prepared from bitter brines in salt lakes are used to train PSO-optimized BP neural networks; the experimental data includes preparation parameters and experimental results, and the number of experimental data groups is greater than or equal to 100; step S2: the PSO-optimized BP neural networks trained in the step S1 can give optimized preparation parameters and predict the whisker ratio with the change of physical and chemical properties of the bitter brine in the salt lakes; and the optimized preparation parameters are adopted to prepare the basic magnesium borate whiskers. The PSO-optimized BP neural networks are used to digitalize the experimental data and provide an optimum experimental scheme for the production of the whiskers from the bitter halogen at any time and accurately predict experimental results, so that the waste of a large amount of manpower and material resources caused by groping experiments is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of preparation of inorganic materials, and more specifically, relates to a method for preparing basic magnesium borate whiskers by using salt lake bittern. Background technique [0002] In salt production, seawater or salt lake water is evaporated and concentrated by the sun in the salt field, and table salt is precipitated. When the brine reaches a certain concentration, the salt is no longer exposed to the sun, and the brine is called bittern. Bittern contains a large amount of magnesium ions, which is an excellent raw material for preparing magnesium salt whiskers. However, limited by the technical level, the utilization rate of bittern is less than 20%, and a large amount of bittern resources are discharged into the sea or circulated in salt pans, which not only causes waste of resources but also affects the ecological balance of offshore waters. Realizing the comprehensive utilization of bittern is an ...

However, limited by the technical level, the utilization rate of bittern is less than 20%, and a large amount of bittern resources are discharged into the sea or circulated in salt pans, which not only causes a waste of resources but also affects the ecological balance of offshore waters

[0003] In practical application, to prepare basic magnesium borate whiskers from bittern, whenever the physical and chemical properties of bittern change, a large number of complicated exploratory experiments must be done to adapt to the new conditions, which consumes a lot of manpower and material resources
