sodium hypophosphite(CAS10039-56-2) is widely used, the price and quality are uneven, HG/T 3253-2009 implementation standard has been difficult to meet the requirements of modern production process. Sodium hypophosphite quality, quality exactly what is good, bad, how to identify it? Below we combine many years of production practice experience, make a simple summary

1, content

The content of high-quality grade can usually reach 101-103%, why the ultra-high 100% content? This question please interested friends call for consultation, the space is limited here, will not go into details. Of course, a very small number of people say they can reach 105% content, we believe that this content can rarely be reached, even if it is reached, storage packaging is a big problem, because this content is easy to absorb moisture. Therefore, we believe that reaching 105% content is purely eye-catching and has no practical significance.

2. Sodium phosphite, Na2HPO3 and sulfate

The lower the two indicators, the better, especially the sulfate indicators to focus on control. In electroless plating and electronic grade manufacturing, if the sulfate content is high, it is hugely destructive to the entire surface treatment process, and can even lead to the scrapping of the reaction tank.

3, heavy metal index

The impact of heavy metal content on product quality needless to say, almost every friend understands. In the export of Europe and the United States, Japan, the United States of America products, heavy metals are not up to standard must be returned. 60% of our company exports to overseas, and the control of heavy metals is stricter than that of peers.

4, the manufacturer's quality control system

Product quality is manufactured, but also the quality control system control out. The two are closely related, there is no perfect quality control means, no matter how advanced technology, no matter how excellent production equipment can not produce high-quality products. Therefore, quality control is the most important guarantee of excellent quality.

5. Packaging

This is easy for many friends to ignore, we may feel that packaging has no impact on product quality? In fact, a big mistake, good packaging in the product after delivery can better moisture-proof, prevent oxidation, the quality of the product after delivery is of great significance.

Sodium hypophosphite quality, quality, price, manufacturer, index, testing means, packaging, etc., are several closely related factors. The choice of good quality, reasonable price is the basic demand of the majority of buyers. We have many years of technical experience in the industry, if you have any questions, please feel free to discuss with us.
