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 true and false when using magnesium sulfate heptahydrate? The detection method is generally as follows:

1. Identify from the aspect of craftsmanship

Magnesium sulfate heptahydrate crystals have different appearances according to different production processes. If the drying process is used, the surface of magnesium sulfate heptahydrate is crystalline, and the surface moisture is more likely to absorb moisture and agglomerate. It will absorb more free water and other magazines; if the drying process is used, the surface water of magnesium sulfate heptahydrate is less, it is not easy to agglomerate, and the fluency of the product is better, and the heptahydrate sulfuric acid produced by the drying process Magnesium can be divided into 0.1-1mm, 0.2-3mm, and 2-4mm three specifications.

2. Identify from the raw material

According to the raw materials used, the quality of the batch can be judged. In order to save costs for customers, some manufacturers use waste acid to produce magnesium sulfate heptahydrate. The color of magnesium heptahydrate produced by waste acid is not as good as that produced by ortho acid. Its main content is also lower than that produced by ortho acid, and the impurity content is relatively higher.

3. Pass the test

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

The quality of the product mainly depends on its material and production process. The quality of magnesium sulfate heptahydrate can be detected by the above method.
