The use of Polyacrylamide for textile wastewater is mainly used as a sizing agent for textiles. Because of its good viscosity, polypropylene can improve the characteristics of adhesion, permeability and desizing. It can promote the anti-static of the fabric, reduce the sizing rate, reduce the glue spots, and break the machine. Rate and shedding. The polyacrylamide sizing liquid has stable properties, with the characteristics of thickening, bonding, and lubrication. It has less dripping, low fabric breakage, and smooth cloth surface, which can effectively improve the quality of textile products.
Polyacrylamide can be used in many wet processing and finishing applications in textile sizing:
1. Light yarn sizing: No matter what process is used, as long as a small amount of polyacrylamide PAM is added to the slurry bath, it can promote the processing fabric to more uniformly absorb the slurry, strengthen the film formation and encapsulate the entire sizing.
2. Desizing: There is also a small amount of polyacrylamide PAM slurry bath to increase the liquid absorption rate, improve the desizing rate, improve the enzyme and oxidative desizing, make the desizing more uniform, and reduce the desizing chemical concentration and reduce the desizing cost .
3. Cooking: The application of polyacrylamide PAM can reduce the processing time and greatly improve the production efficiency.
4. Bleaching: The application of polyacrylamide PAM can be combined with the conventional anti-migration agent to control the migration effect, promote the increase of the color amount, and significantly reduce the cost. Note: PAM is added to the sulfur dye to prevent the appearance of oxidation spots on the fabric, and significantly reduce the fabric defective.
As an efficient flocculant, polyacrylamide is widely used in water treatment of various occupations, whether it is sewage sedimentation and sludge dewatering (also known as sewage sludge dewatering), it is needless to say, the more concerned is the amount of polyacrylamide In fact, the price of the product is very high. If the amount is large, the production cost will increase and the product will not be competitive. So, what is the amount of polyacrylamide? The amount of polyacrylamide is related to the dissolution share and the increase in share, see below.
The amount of polyacrylamide is very small, and the share of the time used to dissolve the cloud is generally one thousandth to three thousandths. Why is it an interval rather than an accurate value? Each occupation is different, the nature of sewage sludge is different, the region is different, the water quality of the water source is also different, and the difference in sewage treatment process directly leads to the difference in the use of Polyacrylamide for textile wastewater, but, according to many customer examples It is more suitable that the dissolution share is from one thousandth to three thousandths.
The dissolving share of polyacrylamide is mentioned above, then the amount of polyacrylamide is more directly affected by the increase in pam. The amount of increase in the solution has not been accurate for a long time, and it is believed that there will be no accurate value. The condition of each application unit is different. In common occupations, the amount of polyacrylamide: coal washing wastewater flocculant increased by 1 ton of coal slime water 1-10 grams of solid sand flocculant increased by 1 ton of mud water increased by 10-20 grams of solid municipal sewage for sludge dewatering and sludge The increase in flocculant is 20-40 grams of solids per ton of sludge. See here, a small way to save the amount of polyacrylamide is to increase pac and then increase pam, which will reduce the polyacrylamide. Use capital.
