Particulate paper retention and drainage aid

Key words:

MPS nano-scale high-efficiency papermaking retention aid is a nano-scale silica sol product modified by metal salt, which is developed by Hubei Daya Company's provincial postdoctoral industrial base in cooperation with Wuhan University's School of Environmental Resources, and has been included in the national major industrial technology development plan and investment plan project. The product has a small particle size, large specific surface area, high negative charge density, strong electrostatic adsorption capacity, can induce particle aggregation into small and uniform, dense and more open three-dimensional network structure of the flocs, can significantly improve the fine fiber and filler, size retention rate in the papermaking process, accelerate the dehydration of pulp, reduce fiber loss in white water, it can effectively improve the uniformity of paper, improve the quality of paper, save fiber raw materials and reduce environmental pollution. It is a new product with high efficiency retention aid, filtration aid, resource conservation and environmental friendliness.

Note: The standard paper system means that the bleached sofiferous wood pulp/bleached hardwood pulp is 60/40, the filler is calcium carbonate, and the bleached wood pulp/CaCO3 is 70/30.

Existing standard binary retention systems refer to cationic starch and cationic polyacrylamide. In the case of the same retention rate, MPS
  
The nano-scale high-efficiency papermaking retention and drainage aids have greatly improved the uniformity of paper.
