[0034] The preparation method of described trace additive is:

[0035] A. Take the mixed plant and solvent to grind at a mass ratio of 3-5:15, collect the grinding mixture, heat the grinding mixture at 90-105°C for 6 hours, cool to room temperature, and put the heated mixture into a steam explosion device , carry out steam explosion, set the pressure at 3.5-4.0MPa, maintain the pressure for 70-80s, and collect steam explosion objects;

[0036] B. Mix the steam explosion product and the mixed enzyme evenly according to the mass ratio of 12~14:1~3, carry out enzymolysis for 8 hours, filter, collect the filtrate, decolorize the filtrate through activated carbon, collect the decolorized liquid, concentrate the decolorized liquid, and concentrate to The volume of the decolorizing solution is 65-70%, the concentrated solution is collected, and the concentrated solution is mixed with ethylene glycol diglycidyl ether at a mass ratio of 1:3 to obtain the additive.

Abstract

The invention relates to a preparation method of a scale inhibitor, and belongs to the technical field of scale inhibition. According to the preparation method provided by the invention, firstly polyglutamic acid and poly(benzyl glutamate) are used as basic raw materials and have good biological activity and degradability, then the poly(benzyl glutamate) is subjected to partial ammonolysis by utilizing action of a mixed solvent and an additive, the ammonolysis product has hydrophilicity and water solubility, a film is formed on the surface by using the polyglutamic acid, at the same time, thepoly(benzyl glutamate) not subjected to ammonolysis is insoluble in water, the formed film has a concavo-convex shape, through sulfamic acid, epoxy polyoxyethylene ether and other mixing reactions, rich active groups are formed to be adsorbed in concave places, the active groups can be well combined with metal ions, finally under the action of trace additives, the polymer is subjected to cross linking to combine the components, under the action of a long-term water flow, the formed film is decomposed, disintegrated and flows, and therefore formation of dirt is further prevented.

Description

technical field [0001] The invention relates to a preparation method of a scale inhibitor, which belongs to the technical field of scale inhibition. Background technique [0002] Water is the basic condition for human survival, but water resources in the world are limited. In order to solve the water resource crisis and adapt to sustainable development, it is necessary to save water reasonably. The amount of cooling water in industrial water accounts for 60-80% of the total water consumption. Therefore, the main goal of saving industrial water is to recycle cooling water, increase the reuse rate as much as possible, and reduce sewage discharge. However, during the use of cooling water, with the continuous circulation and concentration, the content of minerals in the water will continue to increase, which will aggravate the corrosion and scaling of pipes and equipment. Therefore, scale and corrosion inhibitors must be added to cooling water to improve The quality of cooling...
