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!

⑴细度

(1) fineness

硫酸钡正常实用于初级塑料涂料等事业。某个目标没有对于硫酸的品质的任何间接反应，但作为硫酸价格的决议要素，正常来说，硫酸的解决艰难，其价格就越高。

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

非常直观的指示器要取样品。根据视觉的比较，可以看到不同品牌的产品的白度不同。沉淀硫酸钠的价值越高质量越好。

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.

⑶粒子形状

(3) particle shape

沉淀硫酸钡该指数直接影响下游产品，例如，如果塑料或涂料中的颗粒直径不均匀，则颗粒尺寸不均匀，影响产品的整体性能。怎么分辨沉淀硫酸钡的质量好坏呢？当然，它也会影响粒子的形状。一般来说，颗粒大小分布均匀，颗粒形状的影响取决于特定的产物。

Precipitation barium sulfate this index directly affects downstream products, for example, if the particle diameter in plastic or coating is not uniform, the particle size is not uniform, affecting 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.

⑷杂质含量

(4) impurity content

硫酸钡有很多杂质。沉淀硫酸钡由于人工合成而大幅降低了噪音，但在生产过程中或多或少有机械杂质。杂质越少，形成机器的黑点的难度变小，质量也变好。

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.

⑸分散性

(5) dispersion

由于油量低，可节省生产成本，因此分散性也会影响产品质量。

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

沉淀硫酸钡的生产过程中因为一些环节没有到位就会导致它的质量出现偏差，虽然很多厂家都会在出厂前检查一下，但是也会有漏网之鱼，所以我们在购买沉淀硫酸钡的时候也要注意看看质量方面。

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