Non - ionic polyacrylamide is a water - soluble polymer. According to a certain number of polar groups in the molecular chain, by absorbing the suspended solid particles in the water, the particles can be bridged or condensed into large flocculants through charge neutralization. Therefore, it can accelerate the settling of particles in the suspension, accelerate the solution clarification and promote the filtration. It is mainly used for flocculation settling and settling settling of various industrial wastewater.
Properties: polyacrylamide, alias PAM, is a glassy solid. It is easy to absorb water, and the absorption rate is different with the characteristics of derivative ions. Polyacrylamide soluble in water, but also soluble in acetic acid, ethylene glycol, glycerin and amine and other organic solvents. Long-term thermal decomposition, decomposition temperature in 200? above. In the absence of oxygen, 210? carbonization into black powder.As required, polyacrylamide can be processed from non-ionic type into anions, cations and mixed ions of Yin and Yang to form four types of products.
Application: polyacrylamide is an important water-soluble polymer with valuable properties such as flocculation, thickening, shearing, resistance reduction and dispersion. These properties differ from derivative ion to derivative ion with different emphasis. Therefore, it is widely used in oil extraction, mineral processing, metallurgy, chemical industry, papermaking, textile, sugar, medicine, environmental protection, building materials, agricultural production and other sectors.
Storage, transportation and precautions: polyacrylamide is not toxic by itself. Only when the amount of inhalation is greater than five thousandths of the absorption of nutrients due to the intestines and stomach is sticky and harmful. The residual acrylamide monomer in polyacrylamide is toxic. Storage, transportation should pay attention to moisture.
