Problems solved by technology

When the water temperature is lower than 50°C, the dissolution is very slow, and the dissolution speed is accelerated when the water temperature is increased, but above 400°C will accelerate the degradation of the polymer and affect the use effect
(3) Poor dispersion in water
(5) Long stirring and dissolving time

Embodiment 1

[0025] The invention relates to the use of alkaline electrolyzed water as a co-solvent for polyacrylamide, and the dissolution of polyacrylamide uses alkaline electrolyzed water as a co-solvent for polyacrylamide to promote the dissolution of polyacrylamide. When alkaline electrolyzed water is used as a cosolvent for polyacrylamide, alkaline electrolyzed water is an alkaline electrolyzed water composed of 6 molecular groups obtained by separating water with a diaphragm under electrolysis, and the pH value of alkaline electrolyzed water is 9-14 . The weight percent concentration of the polyacrylamide dissolved in the alkaline electrolyzed water is 0.001%-4%.

Embodiment 2

[0027] The invention relates to the use of alkaline electrolyzed water as a co-solvent for polyacrylamide, and the dissolution of polyacrylamide uses alkaline electrolyzed water as a co-solvent for polyacrylamide to promote the dissolution of polyacrylamide.

[0028] To prepare a 0.1% polyacrylamide solution, add three parts of 0.01g polyacrylamide to 100mL alkaline electrolyzed water (pH = 12), 100mL distilled water, and 100mL tap water respectively, stir and dissolve until a uniform polyacrylamide solution is obtained, A homogeneous polyacrylamide solution was obtained.

[0029] solvent Dissolving time / min Viscosity / mPa.s alkaline electrolyzed water 10 13 distilled water 90 12 tap water 90 13

[0030] It can be seen from the comparison that the dissolution time of alkaline electrolyzed water is 89% higher than that of tap water and distilled water, and the viscosity is basically the same.

Abstract

The invention relates to an application of alkaline electrolyzed water serving as polyacrylamide cosolvent, and belongs to the technical field of chemical cosolvent. The application of alkaline electrolyzed water serving as polyacrylamide cosolvent is characterized in that alkaline electrolyzed water is used as polyacrylamide cosolvent for polyacrylamide dissolution so as to promote polyacrylamide dissolution. The alkaline electrolyzed water provided by the invention has the advantages of unique use, high permeability, high activity, high dissolution rate, high solubility, favorable flowability, high use efficiency, simple operation process, low cost, environment friendliness, wide application range and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical co-solvents, and in particular relates to the use of alkaline electrolyzed water as a polyacrylamide co-solvent. Background technique [0002] At present, polyacrylamide (PAM) is a water-soluble polymer with good flocculation and can reduce the frictional resistance between liquids. Thickness, drag reduction, biomedicine, food, etc. Solid polyacrylamide is white powder or translucent granules, with a molecular weight between 4 million and 20 million. It is a high molecular organic compound, insoluble in organic solvents, and relatively difficult to dissolve in water. Therefore, under normal circumstances, powdery polyacrylamide cannot be directly added to water for use. Before use, it must be made into an aqueous solution mother liquor, and then diluted for application. [0003] The conditions for the dissolution of polyacrylamide are very harsh, and have the following characteristics: (1) The ...
