Density and content of polyferric sulfate
The density and content of PFS directly represent whether the product quality is up to standard. Then, what is the density and content of PFS?
What is the density of PFS
The density of polyferric sulfate refers to the ratio of its mass to volume, that is, the specific gravity. Generally speaking, when the density is 1.3, the product is qualified, while when the density reaches 1.45, it can be judged as a high-quality product. In this value, it can be said that the higher the density, the better the product quality.
In production, with the change of temperature and pressure, the volume or density will also change accordingly. Therefore, the control of temperature and pressure is very important in production.
Density meter can be used to detect the density of PFS. The specific operation is: put the product in the measuring cylinder, put the measuring cylinder into the constant temperature water tank, and put it into the densitometer for measurement after the temperature is stable.
What is the content of PFS
Generally speaking, the content of PFS refers to the total iron content of the product. The higher the total iron content is, the better the product quality is. The lower the total iron content is, the lower the density of PFS is. When the content of PFS reaches 11%, the density of liquid product is 1.45.
The total iron content of solid polymerized ferric sulfate products is between 19% and 22%. Products up to 19% are qualified, and those with more than 21% belong to first-class products. Of course, the content is closely related to liquid products.
The above is the description of the density and content of PFS. The density of PFS produced by Henan Zhengyuan is above 1.45, the total iron content of liquid products is 11.5, and the content of solid products is more than 21%.
