Easily degradable drag reducer for drag reduction water

Abstract

The invention discloses an easily degradable drag reducer for drag reduction water. The easily degradable drag reducer for drag reduction water is prepared from, by weight: high polymer: 5-7%, slow release agent: 10-12%, emulsifier: 10-12%, surfactant: 15-17%, organic solvent: 10-12%, mixed ketone: 0.2-0.6%, aldehyde: 0.2-0.6% and the balance deionized water. The easily degradable drag reducer fordrag reduction water has the beneficial effects that through the use of the slow release agent, the use time of the drag reducer is prolonged in the pipeline conveying process, and the adding frequency of the drag reducer is reduced, so that the number of injection stations of the drag reducer is relatively reduced in the whole conveying process, finally less equipment is constructed, and the manpower and the cost are reduced; and compared with the inconvenience of the degradation of a traditional drag reducer, the easily degradable drag reducer for drag reduction water can facilitate the degradation under the action of microorganisms and reduce the environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of drag reducers, in particular to an easily degradable drag reducer for water. Background technique [0002] Drag reducer is a polymer compound that can reduce drag. Adding it to the fluid when the fluid is transported can achieve the effects of increasing the flow rate and reducing energy consumption. [0003] The action mechanism of the drag reducer is that when the fluid is in the turbulent flow zone, it relies on the mutual attraction between the drag reducer molecules to resist the force of the fluid particles, changing the direction and size of the fluid particles, so that a part of the radial force that does useless work is converted into a flow direction. The axial force, thereby reducing the consumption of useless work, macroscopically reduces the friction loss of the fluid, that is, plays a role in reducing drag. [0004] The existing drag reducing agent for water has the following deficiencies ...
