Polyacrylamide is acrylonitrile as raw materials, with flocculation, thickening, shear resistance and other properties, soluble in water, almost insoluble in benzene, ether, esters, acetone and other general organic Solvent, almost insoluble in organic solvents, water solution almost transparent viscous liquid, non-toxic, non-corrosive, solid polyacrylamide PAM hygroscopicity, hygroscopicity increases with the increase of the degree of ion, heated to 100 ℃ good stability , But more than 150 ℃ in the decomposition of nitrogen in the production of easily imidized in the molecule but not soluble in water, the suspension of material through the electric and bridging adsorption, flocculation through mechanical, physical, The role of chemistry, from the role of adhesion, in both neutral and acid conditions have thickening effect, when PH value above 10 ℃ susceptible to hydrolysis of the PAM. In the semi-network structure, thickening will be more effective in reducing the frictional resistance of the fluid, adding trace PAM in water can reduce the resistance of 50 80%.
Principle of the action of the filter polyacrylamide PAM Introduction:
1. Adsorption bridge: The PAM molecular chain is fixed on the surface of different particles, forming a polymer bridge between the particles so that the particles form an aggregate settlement.
Principle of flocculation: When used in flocculation, it is related to the surface properties of flocculant species, especially the dynamic potential, viscosity, turbidity and the PH value of the suspension. The reason to join the surface charge of the opposite PAM, can slow down potential and condensation.
3. Surface Adsorption: Various Adsorption of Polar Group Particles on Polyacrylamide PAM Molecular.
4. Enhancement: PAM molecular chain and dispersed phase through a variety of mechanical, physical, chemical and other roles, the dispersed phase implicated together to form a network, which play a role in enhancing.
Application of Polyacrylamide PAM Description:
1, building materials industry in the building materials industry, can be used to improve wet-process cement production capacity of settling tank and cement filterability, improve the kiln material Homogeneity. The retention of fibers and additives in inorganic materials and lignocellulose based insulation panels can be improved. Can be added to the water wall adhesive tape cement compound formula to improve the quality of construction.
2, the construction industry in the construction industry as a wallboard (paper), asbestos products and other adhesives. PAM gel can be used for caulking, repair and plugging of buildings. Caulking cement with PAM shows excellent bond and adhesion over a wide range of temperatures and relative humidity.
3, the preparation of slurry, in order to replace the grain made of sizing material, can save a lot of food. The use of its strong hygroscopic characteristics, can reduce the broken yarn spinning rate, improve the hydrophilicity of synthetic fibers. Used as a pigment printing aid, fastness, high brightness, but also can be used as leveling agent.
4. Textile, Printing and Dyeing Industry In the textile and printing and dyeing industries, PAM is used as sizing agent and fabric finishing agent, and the anti-mold protective layer can also be formed on the surface of the fabric. For polyester, cotton and other fiber warp sizing agent and cotton anti-wrinkle agent.
Use method of filter polyacrylamide
1. Before using, dissolve solid particles into 1 - 5 concentration aqueous solution, in order to exert its effect rapidly.When dosing, we should adopt gradual home-medicine method , Slowly cast in water, then evenly dispersed in water, dissolved
2, usually add about 0.5 --- 1 aqueous solution, but the suspension of high concentration and high viscosity occasions, it is recommended When the aqueous solution is further diluted to 0.1, it will be easy to mix to give sufficient effect.
3. The concentration of cation and non-ion is higher than that of the anion. (Depending on the water, the concentration may be adjusted as appropriate High concentration of turbidity, low concentration, low turbidity can be an appropriate increase in concentration), filter manufacturers suggest that you match the concentration of 5 - 1%.
Filter Polyacrylamide in use Note:
1 When preparing polyacrylamide PAM aqueous solution, it should be carried out in enamel, galvanized, aluminum or plastic drum, and can not be formulated and stored in iron container.
2. When dissolved, care should be taken that the product is slowly and evenly added to the dissolver with agitation and heating measures, the knot should be avoided, the solution should be prepared at a suitable temperature, and the mechanical shears It is recommended that the stirrer be 60 rpm, otherwise it will lead to polymer degradation, thus affecting the use effect.
3. Polyacrylamide aqueous solution shouldWhen the solution is ready for use for a long time, its performance will gradually decrease depending on the quality of the water.
4. After adding an aqueous flocculant solution to the suspension, if the solution is vigorously stirred for a long time , Will destroy the floc formed already
Application scope of filter polyacrylamide:
1, Used as a retention aid and reinforcing agent in the process of paper making
2. Water treatment Coagulant, flocculant, sludge dehydration agent
3. Oil Drilling for precipitation, oil displacement agent.
4, polyacrylamide PAM is also widely used in thickening, stabilizing colloid, drag reduction , Bonding, filming, biomedical materials, etc.
