The principle of hydraulic drawing of buildings

In recent years, aluminum formwork and prefabricated components have been used more and more in the construction industry. The application of these new technologies has also brought challenges to some traditional construction methods, and the corresponding supporting processes have not kept up with it in time, resulting in a A series of problems arise. As an important link in the entire construction process, grass-roots brushing also faces challenges in its construction method.

The principle of building hydraulic brushing is to pressurize the water to an ultra-high pressure state of 200-250 MPa with a water pump. Through throttling control, it is sprayed from the nozzle to form a "water jet", which is "carved" on the concrete wall. A groove with a depth of about 1mm is formed to form a rough surface, and at the same time remove hidden dangers such as release agent and floating ash.

Process advantage

1. After brushing, tile adhesive can be used directly to tile the tiles, eliminating the need for grinding, rolling interface agent, hanging net, slurry throwing, plastering and other processes, saving time, materials and labor.
2. Efficiently solve problems such as empty drums, cracks, etc., one delivery, no risk of rework,
3. The construction efficiency is high, one piece of equipment is operated by one person, and the daily operation volume can reach 800m'.
4. Clean and environmentally friendly, no dust pollution, water can be quickly air-dried.
5. The brushing effect can be customized according to different needs (the depth of the brushing, the density, etc. are variable).
6. It is convenient to wear and push the construction, and it can be cut in at any time according to the progress of the project.

Scope of application

The high-pressure water brushing process is suitable for the base treatment of smooth shear walls, especially concrete walls and prefabricated components (PC). The traditional slurry throwing process is less effective when dealing with this kind of wall, because the wall surface of aluminum mold casting and PC board is smoother, and a large amount of mold release agent and floating ash remain on it, causing the mortar itself to be different from the wall. The bonding of the surface is not strong enough, and plastering, tiling, etc. on this unstable base layer will greatly increase the hollow rate.
High-pressure water brushing is to directly break the smooth surface of the concrete wall to form a rough surface, so that cement mortar, tile adhesive, etc. penetrate into the wall to a greater extent, increase the contact area, and also remove hidden dangers such as release agent and floating ash. , and then greatly improve the adhesion, and fundamentally solve the problem of hollowing.

Frequently Asked Questions | Our Solutions

For a long time, problems such as hollowing and falling off of walls, ceramic tiles and thermal insulation boards have occurred from time to time, and serious safety accidents have been caused. For the walls and PC components casted by aluminum molds, the surface is smoother, the water absorption is poor, and there is a large amount of mold release agent and floating ash residue, which leads to the traditional brushing process such as slurry throwing and shotcrete. The drum rate has increased significantly. It is precisely based on this market demand that the high-pressure water brushing process came into being. This process removes the smooth surface of the concrete wall, forms a rough surface, and increases the contact between cement mortar and tile adhesive with the base layer. At the same time, the hidden dangers such as release agent and floating ash are removed, thereby greatly improving the bonding force, fundamentally solving the problems of hollowing and cracking that are easy to occur after plastering and tiling, and can reduce the construction process and improve the construction efficiency.

Frequently Asked Questions | Use and Maintenance of Hose

1) According to the conditions of use, correctly select the variety and size of the hose to prevent misuse and substitution. It is strictly forbidden to use a low-pressure hose instead of a high-pressure hose, or use an ordinary (air or water) hose instead of an acid (alkali) or oil for corrosion. Special hoses for sexual media are used. (2) For the hose that transports acid (alkali), oil and other media, after each use, the medium in the tube should be removed and cleaned in time to prevent the corrosion of the tube body by the residue. (3) The hoses for seasonal use should be properly stored after being cleaned after use.

Frequently Asked Questions | Application of High Pressure Water Washer

All kinds of equipment used in the field of industrial production often produce oil scale, scale, coking, high temperature polymers, deposits, corrosion, etc., which significantly affect the equipment.To ensure the efficiency and safety of equipment, cleaning them is inevitable. Compared with the previous manual cleaning, chemical cleaning and ultrasonic cleaning, high-pressure (ultra-high) water jet cleaning has the great advantages of high efficiency, wide range and good effect.

FAQ | The harm and prevention of high pressure water jet to human body

Set up an isolation screen to prevent the human body from being impacted by the ejected water jet and scattered water droplets during processing; the operator should at least wear protective glasses, preferably a protective mask.
