In the sugar industry, the flocculant with good performance must be used in the clarification treatment of syrup, and the type and preparation method of flocculant are very important. The use of high polymer polyacrylamide (degree of hydrolysis of 25%-30%) is more suitable for sugar plant applications. Adopt advanced cane juice clarification technology, efficient polyacrylamide flocculant to remove as much non-sugar as possible, so as to improve the quality of green juice. In addition, it can also be used to reduce the formation of scale in sugar refining equipment. Nowadays, China has produced polyacrylamide flocculant specialized in sugar industry. The relative molecular weight is 200X10⁴, and the dosage is 2mg/L, which can increase the sedimentation rate by 20 times.

Application of cationic anionic non-ionic polyacrylamide in building and building materials industry


1. Food processing and sugar industry


Polyacrylamide can be used for purification of various meat, fruit and vegetable cleaning water and clarification of fruit beer and beer.


As a flocculant, polyacrylamide can be modified with modified starch to increase the binding amount of water. It is prepared with 15 parts of polyacrylamide and 85 parts of starch.

2. Building materials industry


In the building materials industry, it can be used to improve the production capacity of the settling tank and the filtrability of cement in the wet cement manufacturing process, and improve the uniformity of kiln materials. The retention of fibers and additives in insulation panels based on inorganic materials and wood fibers can be improved. It can be added to the composite formula of water wall belt bonding cement to improve the construction quality.


3. Construction industry


In the construction industry for wallboard (paper), asbestos products and other adhesives. Polyacrylamide can be used for building caulking, repair and leak plugging. The joint cement with polyacrylamide exhibits excellent nodular and adhesive properties over a wide range of temperature and relative humidity.


4. Electroplating industry


In electroplating solution, the addition of polyacrylamide can make the metal precipitation homogenization, make the coating more bright. Polyacrylamide can be used as a protective colloid to improve emulsion stability.


5, textile, printing and dyeing industry


In the textile, printing and dyeing industry, polyacrylamide used as sizing agent, fabric finishing agent, but also in the fabric surface to form a protective layer against mold. It can be used as warp sizing agent for polyester, cotton and other fibers and anti-wrinkle agent for cotton. Make up grout, in order to replace the grout that grain makes, can save a lot of grain. The breaking rate of spinning yarn can be reduced by its high moisture absorption. Improve the hydrophilicity of synthetic fiber. Used as printing additives for coating, fastness, high brightness, can also be used as levelling agent.


6. Fluid transportation


One of the most promising applications of acrylamide polymers is to reduce hydrodynamic resistance in turbulent flow. This effect has a wide range of applications, such as to increase the coverage of fire sprinkler; Used for reducing pipeline resistance in fluid transportation; Used to paint on the surface of ships or submarines, can reduce navigation resistance, improve shipping speed; It can improve the transportation conditions of coal slurry in coal liquid transportation, and can also be used for suspension of turbidity water and emulsion high speed suction.


7. Used as a water-absorbing resin


Superabsorbent molecules are a kind of new functional polymer materials developed in the mid 1970s, which have been widely used in industry and daily life. Most of these polymers are metal salts of acrylic acid and acrylamide or other unit copolymers. These gels have high strength and can absorb up to 2,000 times more water. Using light oil as continuous spAN-60 suspension stabilizer, bisacrylamide as crosslinking agent and persulfate as initiator, a high absorbent copolymerization of acrylate-acrylamide was synthesized by reverse suspension polymerization. The product was microspherical with average particle size less than 40um. The average particle size and water absorption of the product are affected by the stirring speed, the amount of suspension stabilizer, the amount of crosslinking agent and other factors. The water absorption of the product is about 300 times.
