Boric acid products also have a quality index system

Chemical products, which are more and more important in our lives, play an increasingly important role. In the process of purchasing, we also need to look at their quality index system. Only when the index is reached, can we buy its products. In production practice, boric acid Manufacturers often use the main content as the criterion for judging whether boric acid is qualified, but the quality index system of boric acid products is composed of seven main indicators. Among the seven indicators, as long as one indicator does not meet the standard requirements, it is a substandard product.

In terms of index control, the main content index is easy to control. Even if the impurity index is unqualified, the main content index may meet the standard requirements. Products with qualified main content and unqualified impurity index are not acceptable to users. Therefore, it is one-sided and unreasonable to simply evaluate the quality of a product based on the main content. From the perspective of full analysis, the qualified rate of one-step boric acid in my country is almost zero.
