Method for preventing sodium bicarbonate from caking

Abstract

The invention discloses a method for preventing sodium bicarbonate from caking. The method comprises the following operation steps: selecting a certain amount of anti-caking agent, wherein the anti-caking agent adopts feldspar powder materials, and the feldspar powder materials include orthoclase, albite, anorthite, baryta feldspar, baryta ice feldspar, microplagioclase, sanidine and all minerals taking feldspar as a main component; and selecting a certain amount of baking soda product, mixing the anti-blocking agent and the baking soda product for use, and matching a certain amount of feldspar powder and a certain amount of baking soda product, and the particle size D50 value of the product is about 10 microns. According to the method for preventing the sodium bicarbonate from caking, the crushed sodium bicarbonate product and the feldspar are uniformly mixed according to a certain proportion and then are sealed, so that long-time storage of the crushed sodium bicarbonate product can be realized, the caking phenomenon of the sodium bicarbonate in the storage process is effectively avoided, relatively high dispersing performance of the product is kept, the application effect of the product is not affected, and a better application prospect is brought.

Description

technical field [0001] The invention relates to the chemical field, in particular to a method for preventing sodium bicarbonate from agglomerating. Background technique [0002] Sodium bicarbonate, also known as baking soda, is a kind of carbonate, white crystalline powder, which can be widely used in industry, food and pharmaceutical industries. The problem of sodium bicarbonate agglomeration has always been a difficult problem in the industry, especially in hot and humid summer, the agglomeration problem is particularly serious, which brings great inconvenience in use. At present, there are three main methods for the industry to solve sodium bicarbonate agglomeration : Increase and improve the cooling device to reduce the packaging temperature of sodium bicarbonate; improve the crystallization quality of sodium bicarbonate and reduce the temperature after drying; carry out reverse chopping treatment on the finished sodium bicarbonate before agglomeration.

Problems solved by technology

[0003] Existing methods for preventing sodium bicarbonate from agglomerating have certain disadvantages in use. At first, the above three methods of preventing sodium bicarbonate from agglomerating have improved the complexity of the production process, added unnecessary procedures, and greatly increased It reduces the production cost of the product, is not a simple and effective solution, and is not conducive to people's use. In addition, the above three methods of preventing sodium bicarbonate from agglomerating have increased the complexity of the production process, added unnecessary procedures, and greatly It increases the production cost of the product, is not a simple and effective solution, and brings certain adverse effects to people's use process. Therefore, we propose a method to prevent sodium bicarbonate from agglomerating
