Cement concrete scale cleaning agent and preparation method thereof

Abstract

The invention relates to a cement concrete scale cleaning agent and a preparation method thereof. The cement concrete scale cleaning agent is prepared from the following raw materials in percentage by mass: 2-30% of organic acid, 1-5% of builder, 0.5-5% of penetrant, 0.1-2% of tackifier and the balance of tap water. The preparation method comprises the steps: preparing production equipment; accurately weighting the raw materials; adding half of the tap water, sequentially adding the organic acid, the builder, the penetrant and the tackifier while stirring at the rotating speed of 600-700rpm, and after all the raw materials are added, stirring at the rotating speed of 1000-1500rpm until the raw materials are completely dissolved; adding the residual tap water, and then, uniformly mixing at the rotating speed of 600-700rpm to obtain a cleaning agent product. According to the invention, the cleaning agent cannot corrode the equipment and can be used for clearing hardened cement concrete scales on the surface of the equipment without knocking, not only is the equipment protected, but also the water obtained after cleaning can be treated to be reused, so that the cleaning agent is pollution-free, safe and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of chemical cleaning, and in particular relates to a cement concrete scale cleaning agent and a preparation method thereof, which are used for removing solidified cement concrete and mortar scales on concrete production, transportation and construction equipment. Background technique [0002] Cement concrete has been widely used in various construction projects. In the process of production, transportation and construction, cement concrete must be in contact with various production equipment, transportation vehicles and construction tools, which causes a lot of adhesion inside and outside the vehicles and equipment. Before the cement slurry and concrete blocks are completely solidified and hardened, the production and construction units usually use the method of flushing with pressure water guns to remove the concrete, but if these equipment and vehicles are not cleaned in time, or Cleaning but incomplete ri...

Problems solved by technology

The cleaning agent used in the chemical cleaning method is composed of oxalic acid, dilute hydrochloric acid and dilute sulfuric acid, etc., but these acids will cause corrosion to metal equipment and also seriously affect the service life of the equipment

If the method of physical knocking is used, it is very difficult to operate due to the limitation of the equipment shape and internal space. Even if it is convenient to knock off the equipment shell and other parts, the paint on the equipment will often be removed when the hardened cement concrete is knocked off. The film is peeled off together, causing damage, and excessive knocking may even cause deformation of the device, affecting the accuracy and use of the device
