Whether in liquid materials or in solid and gaseous materials, impurities are easily mixed, which affects the use of various products. The content of impurities in the water treatment agent can directly affect the use effect of the agent. In industrial circulating water, too much impurity of the agent will pollute the water quality, and for the cleaning agent, there will be substances that are invisible to the naked eye. Small product surface, serious will directly affect product quality. So, what is the source of impurities in the water treatment agent? Here is a detailed introduction for everyone:
1. Impurities introduced by impurities in raw materials, such as phosphorus trichloride, are often impregnated with pentavalent phosphorus, and orthophosphoric acid is often contained in organic phosphonic acid water treatment agents.
2. The raw materials are not completely reacted. For example, ethylenediamine in EDTMP is not completely residual due to the reaction.
3. The intermediate of the reaction or a by-product of the reaction, such as chloride ion and phosphorous acid in the organic phosphonic acid water treatment agent, is an intermediate product.
4. Other elements such as iron ions introduced in the production process and production pipelines due to corrosion during the production process.
The above are the four sources of impurities in the water treatment agent, and it can be found that the types of impurities introduced in different sources are also different. Because the pharmaceutical product is directly immersed in the cleaning agent and then dried, the impurities are also a very important quality indicator, and we need to pay more attention when checking.
