Method for determination of moisture content of magnesium sulfate heptahydrate

Magnesium sulfate heptahydrate has superior chemical properties in the chemical industry, and its application range is relatively wide. One of the issues that people are more concerned about is the relevant content of magnesium sulfate heptahydrate moisture measurement, which is sorted out by Xiaobian today and studied with you.

1. Pass the test

Of course, the better way is to determine the humidity of magnesium sulfate heptahydrate through third-party testing.

2. Distinguish from the process

Magnesium sulfate heptahydrate is a kind of crystal, and its appearance varies according to different production processes. If the rotary drying process is used, the surface water of magnesium sulfate heptahydrate is more, and it is crystalline. If there is more water on the surface, it is easy to absorb moisture clumps, which will absorb more free water and other magazines. If the drying process is used, the surface moisture of magnesium sulfate heptahydrate is less, it is not easy to caking, and the product fluency is better. Magnesium sulfate heptahydrate produced by the drying process can be divided into three specifications.

3. Distinguish from raw materials

At the same time, we can also judge the quality of magnesium sulfate heptahydrate according to the raw materials used. Some manufacturers use waste acid to produce magnesium sulfate heptahydrate in order to save costs for customers. The color of magnesium sulfate heptahydrate produced by waste acid is not as good as that of primary acid, the main content is lower than that of primary acid, and the impurity content is relatively high.

As we all know, the quality of the product mainly depends on its material and production process, and the moisture of magnesium sulfate heptahydrate can be detected by the above method.
