How to detect the quality of magnesium sulfate heptahydrate

The chemical properties of magnesium sulfate heptahydrate are relatively superior, and its application range is also relatively wide. So, how to distinguish its quality when using magnesium sulfate heptahydrate? The detection methods are generally as follows:

1. Identify from the perspective of craftsmanship

The appearance of magnesium sulfate heptahydrate crystals varies depending on different production processes. If the drying process is used, the surface moisture of magnesium sulfate heptahydrate is relatively high, which is crystalline. If the surface moisture is relatively high, it is easy to absorb moisture and clump, and it will adsorb more free water and other magazines; If the drying process is used, the surface moisture of magnesium sulfate heptahydrate is relatively low, making it less prone to agglomeration, and the smoothness of the product is relatively good. The magnesium sulfate heptahydrate produced through the drying process can be divided into three specifications: 0.1-1mm, 0.2-3mm, and 2-4mm.

2. Identify from the perspective of raw materials

The quality of this batch of goods can be judged based on the raw materials used. Some manufacturers, in order to save costs for customers, use waste acid to produce magnesium sulfate heptahydrate. The color of the magnesium heptahydrate produced by waste acid is not as good as that produced by original acid, and its main content is also lower than that produced by original acid, with a relatively higher impurity content.

3. By detection

A good method, of course, is to judge the quality through third-party testing.

The quality of magnesium sulfate heptahydrate products mainly depends on its materials and production process. Through the above methods, its quality can be tested. Therefore, major manufacturers of magnesium sulfate heptahydrate are also requested to grasp these two processes to ensure the quality of magnesium sulfate heptahydrate.
