Problems solved by technology

Compared with macromolecular groups, the physical and chemical activity of monomolecular water is stronger, but because there is little monomolecular water in ordinary water, the activity of water is not high, and the cement cannot be fully hydrated, and its hydration can only be performed on the surface of cement particles. conduct

Abstract

The invention discloses a pre-magnetization synergism device for a liquid cement grinding aid. The pre-magnetization synergism device comprises a liquid inlet tube 1, a variable-frequency liquid delivery pump 2, a permanent magnet 4, an electromagnetic flowmeter 5 and a discharge tube 6, which are orderly connected through a pipeline 3, wherein the flow velocity of the variable-frequency liquid delivery pump is controlled by a control unit 7. The invention also discloses a method for carrying out pre-magnetization synergism on the liquid cement grinding aid by using the pre-magnetization synergism device for the liquid cement grinding aid. By adopting the method, pre-magnetization treatment is carried out on the liquid cement grinding aid, so that the dispersive capacity of the cement grinding aid at the surface of the material is improved; the grinding and enhancing effects are improved; the cost performance of the cement grinding aid is obviously improved; and the pre-magnetization synergism method is simple in process, and low in investment cost.

Description

technical field [0001] The invention belongs to an application device and method of cement grinding aids, in particular to a pre-magnetization synergistic technology for liquid cement grinding aids. Background technique [0002] Under the action of external force, the conductor moves to cut the magnetic field line, and the conductor will generate electric charge and electromotive force that makes the charge move, and at the same time, changes such as current and potential difference will be generated, thereby generating electric energy. The higher the magnetic field strength, the denser the magnetic force lines, the faster the movement of the conductor, the lower the resistivity of the conductor, the more electric energy will be generated, and the more significant the physical changes in the conductor will be. This is the famous Ferrari electromagnetic theory. [0003] When the conductor cutting the magnetic force line is a liquid with a certain flow velocity and a certain ...
