Polyacrylamide (PAM) is a multifunctional polymer with a wide range of uses. The following are the main functions and uses of polyacrylamide:
Flocculant:
Polyacrylamide can absorb suspended particles in water, act as a link and bridge between particles, make fine particles form larger flocs, and accelerate the precipitation rate.
Coagulant:
In water treatment, polyacrylamide is used in combination with inorganic flocculants to significantly change the water quality.
Thickener:
Polyacrylamide has a thickening effect under both neutral and acidic conditions.
Oil displacement agent:
In oil extraction, polyacrylamide aqueous solution is used as an oil displacement agent and drilling mud conditioner.
Filter aid:
In the field of papermaking, polyacrylamide is widely used as a filter aid, which can improve the quality of paper and the dewatering performance of the pulp.
Sizing agent:
In the textile industry, polyacrylamide is used as a sizing agent for fabric post-treatment, which can generate a soft, wrinkle-resistant, and mildew-resistant protective layer.
Soil moisturizer:
In agriculture, polyacrylamide, as a highly absorbent material, can be used as a soil moisturizer and seed culture agent, etc.
In summary, polyacrylamide plays an important role in many industries due to its unique chemical and physical properties.
