Problems solved by technology

The first method of removal requires a lot of manpower, and at the same time, the wear on the surface of the material is also very serious, and the effect of complete removal cannot be achieved.
The second is to use oxalic acid to remove. Cement is alkaline. Strong acid can quickly and completely dissociate the accumulated cement scale, but it is more corrosive to the surface of the material.

Abstract

The invention discloses a cement cleaning agent as well as preparation and application methods thereof. The cement cleaning agent consists of a solution A, a solution B and a solution C, the solution A is prepared from the following components in percentage by mass: 16 to 32 parts of nano magnesium hydroxide, 15 to 26 parts of cationic surface active agent and 942 to 969 parts of water; the solution B is prepared from 240 to 320 parts of organic acid, 180 to 260 parts of inorganic acid, 98 to 127 parts of dispersing agent, 8 to 14 parts of complexing agent and 279 to 474 parts of water; the solution C is prepared from 980 to 988 parts of water and 12 to 20 parts of urea. The cement cleaning agent can penetrate into hardened cement to efficiently remove thick cement residues adhered to the surface of a material, and meanwhile, the material is not damaged. The prepared cement cleaning agent is high in efficiency, good in effect, suitable for large-scale operation and good in adaptability, and has good social benefits and economic benefits.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a cement cleaning agent and a preparation and application method thereof. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material that can be hardened in air or in water to form a slurry after being stirred with water, and can firmly bind sand, stone and other materials together. Cement is an important building material. The mortar or concrete made of cement is strong and durable, and is widely used in civil engineering, water conservancy, national defense and other projects. Cement is the basic raw material of the national economy, and the cement industry is closely related to economic construction. For a long period of time in the future, cement will still be the main building material of human society. [0003] Cement brings convenience to our life, promotes the development of social and economic construction, and is an irreplaceable material for ...
