How to distinguish the quality of precipitated barium sulfate?

Precipitated barium sulfate is a kind of barium sulfate processed from barium sulfate. It will be used in many industries, especially in the coating industry and in the paper industry. However, when these products are used in these industries, there will be quality requirements. How can we distinguish the quality of precipitated barium sulfate? Let's have a look!

(1) fineness

Barium sulfate is normally used in primary plastic coatings. A certain target does not have any indirect reaction to the quality of sulfuric acid, but as a decisive factor of the price of sulfuric acid, normally, the solution of sulfuric acid is difficult, and the higher the price is.

(2) whiteness

Very intuitive indicator to take samples. According to the visual comparison, we can see that the whiteness of different brands of products is different. The higher the value of precipitated sodium sulfate, the better the quality.

(3) particle shape

Precipitated barium sulfate this index directly affects downstream products, for example, if the particle diameter in plastics or coatings is not uniform, the particle size is not uniform, which affects the overall performance of the product. How to distinguish the quality of precipitated barium sulfate? Of course, it also affects the shape of the particles. Generally speaking, the particle size distribution is uniform, and the influence of particle shape depends on the specific product.

(4) impurity content

Barium sulfate has many impurities. Precipitated barium sulfate can reduce the noise greatly due to artificial synthesis, but there are more or less mechanical impurities in the production process. The less impurities there are, the less difficult it is to form black spots on the machine and the better the quality.

(5) dispersion

Due to the low amount of oil, the production cost can be saved, so the dispersion will also affect the product quality.

In the production process of precipitated barium sulfate, because some links are not in place, it will lead to quality deviation. Although many manufacturers will check it before leaving the factory, there will also be some fish missing the net, so we should pay attention to the quality when purchasing precipitated barium sulfate.
