Polyacrylamide manufacturers have relatively strict quality control over their products. When purchasing products, some customers will ask whether polyacrylamide is a dangerous good and whether it is harmful to the human body. Today, we will explain this to the customers. Polyacrylamide itself and its hydrolyzed products are non-toxic and non-toxic
It is harmful. The possible toxicity it may have comes from the residual monomer acrylamide. After such a long period of technological upgrading, the production process of polyacrylamide has become very mature.
The residual monomer acrylamide is also very little. Moreover, polyacrylamide is typically used in industrial fields, while the amount used in the cosmetics field is relatively small and the content is also extremely low. As workers of polyacrylamide manufacturers, the current dust control and protective measures are all very complete, and there is basically no possibility of ingestion
Health departments of various countries have regulations that the residual amount of acrylamide in industrial polyacrylamide products is generally 0.5% to 0.05%. When used for the purification treatment of industrial and urban sewage, the content of acrylamide generally does not exceed 0.2%. When used for the treatment of direct drinking water, the content of acrylamide should be less than 0.05%. When we are in production, we strictly follow the prescribed indicators.
The polyacrylamide standard issued by the World Health Organization in 1985 states that when the residual acrylamide content in polyacrylamide is controlled below 0.05% and the dosage is controlled, it should be treated
The content in the water will be less than 0.25ug/L, meeting most drinking water standards. PAM products have long been approved by the United States Environmental Protection Agency or the Food and Drug Administration and can be used
Fields such as drinking water, sugar juice clarification, fruit and vegetable washing, etc. PAM is non-toxic, but the raw material monomer AM of PAM is toxic, especially harmful to the nerves of mammals
Therefore, in Europe, America and even in China, there are strict requirements for the residual monomer AM content in food-grade PAM, generally requiring it to be less than 0.05%, and the dosage applied is also limited
For instance, it is applied in fields such as wastewater treatment and sludge dewatering.
We have always been dedicated to the development of the sewage treatment water purifying agent business, adhering to the enterprise spirit of integrity, pragmatism, innovation and development, and have received wide acclaim from customers!
