Anionic polyacrylamide
Main uses: Different molecular weights can be selected according to different uses and user requirements for product performance. Used for industrial wastewater treatment, especially for wastewater with suspended particles, coarser particles, high concentration, positively charged particles, and neutral and alkaline water values, such as steel plant wastewater, electroplating plant wastewater, and metallurgical wastewater. The treatment effect of coal washing wastewater and other sewage is very good.
Drinking water treatment. The water from many water plants in my country originates from rivers with little mud and high mineral content. It is relatively turbid. Although it has been subjected to sedimentation treatment, it still does not meet the requirements and requires the addition of flocculants. In order to make the water quality clear, many water plants use inorganic flocculants, but the dosage is large, resulting in an increase in sludge volume and the effect is not good. Anionic polyacrylamide is used as the flocculant, and the dosage is inorganic flocculation
One-third but the effect is several to dozens of times that of inorganic flocculants. It has better effects when used in conjunction with anionic polyacrylamide in river water with serious organic pollution.
, used for the recovery of lost starch and distiller's grains from starch factories and alcohol factories. Nowadays, the wastewater discharged by many starch factories has high starch content. After discharge, it affects the environment and wastes resources. Add
to cause starch to precipitate. The precipitate is filtered by a filter press and turned into cakes that can be used as feed. A large number of alcohol plants The distiller's grains are processed using this process, and the distiller's grains are recycled and great economic benefits have been achieved.
, used as water plugging agent for oilfield profile control and water plugging, and as oil displacement agent for tertiary oil recovery.
, used as papermaking additives,
It is widely used in papermaking, and can be used as long fiber papermaking dispersant, dry and wet reinforcing agent, retention aid, filter aid and flocculant for papermaking wastewater, etc.
