Polyacrylamide product use and usage
Polyacrylamide product use
1.Polyacrylamide is widely used in the chemical additives in the oil exploitation (oil additives), drilling mud, water shutoff profile control agent, three oil displacement agent, etc..
2.Polyacrylamide is widely used in mine mineral processing reagents, such as copper, iron ore, gold ore flotation and tailing water treatment, coal mine preparation and flocculation water treatment, starch factory and alcohol plant starch and distiller's grains of recovery.
3.Polyacrylamide is widely used in drinking water, water supply and drainage, such as water treatment, petrochemical industry, wastewater treatment, wastewater treatment, industrial wastewater treatment, wastewater treatment, industrial wastewater treatment, salt water purification, phosphoric acid process flocculation and precipitation, etc..
4.In the use of various sludge dehydration, according to different sludge properties of the corresponding product grades, can be effectively used in the sludge into the dewatering machinery before gravity sludge dewatering. Dehydration, resulting in floc, non stick filter, filter press is not dispersed, less dosage, high dewatering efficiency, the cake moisture rate in 80% the following. .
5.In paper making, polyacrylamide is used as paper reinforcing agent, the textile industry as sizing agent and fabric finishing agent, thickening agent for the construction industry is used as a coating, cement increased viscosity and chemical grouting agent, can also used for controlling desert sand, green water retaining agent, soil improvement agent.
Using method of polyacrylamide
1.Kinds of polyacrylamide have been serialized, according to the different uses to select different grades, the dosage according to different purposes and different, before the use of industrial can first beaker test select the appropriate grades and determine the dosage.
2.The use of dilute solution of the form (anionic, nonionic, cationic species in the 0.3% - 0.05% species of Polyacrylamide in general, the concentration of 0.1% - 0.2% is appropriate), and the concentration of the more dilute molecular chain, the better the effect.
3.Preparation, will join in water with stirring and dissolving tank, open stir, weighing the flocculant dry slowly added to the mixing water to avoid powder agglomeration, the in water well dispersed, swelling and dissolution, and the flocculant and fully aged can get satisfactory result
4.Strong mixing can make the mechanical degradation of the flocculant, the effect of the use of the effect, so the mixing speed of 100 - 300rpm is appropriate.
5.The operation should be dissolved in plastic, ceramic, stainless steel corrosion in a stirred tank, avoid rust.
6.Dissolved good flocculant with screw pump, diaphragm pump and other low shear pump is appropriate.
