The polyurea anticorrosive paint has good physical properties, anticorrosive properties, moisture and heat resistance, salt fog resistance, light retention, color retention and weather resistance. It can be used at - 50-120 ℃ for a long time. The elastomer shall be sprayed with spraying tools, and the rigid body shall be sprayed with high-pressure airless spraying, or manually brushed.
The polyurea anticorrosive coating adopts a one-time coating process. No matter how large the area is, there is no joint. It is also a dust-free polyurea coating with strong adhesion, friction resistance and hardness.
Spray polyurea waterproof and anti-corrosion coating to make it more flexible, rigid and colorful. It is compact, continuous and seamless, completely blocking the penetration of water and oxygen in the air.
Polyurea anticorrosive coating plays an important role in the use of industrial wastewater pool. It can well protect the industrial wastewater pool from too much corrosion, and can be used for a long time. What are the main treatment works of the industrial wastewater pool during the construction of polyurea anti-corrosion coating? 1. Cleaning the base course Cleaning the base course, polishing the base course to clean sharp edges and corners and loose layers, and cleaning up the ash tips, debris, dirt and other impurities, locally unqualified base course shall be repaired with putty, and the internal and external corners shall be made into circular arcs; Acceptance shall be carried out after the base course is complete. 2. Construction treatment The weak links in construction shall be treated. After an additional layer of not less than 100mm is brushed at the junction of the plane and elevation of the building project, the pipeline passing through the waterproof layer shall be brushed with an additional layer of not less than 100mm wide around it before normal construction. During construction, the direction of the next layer and the previous layer shall be vertical during manual painting, and there shall be no underbrush, missing brush or missing spray.
Compared with the traditional environment-friendly spraying process, the spraying polyurea elastomer process has the following advantages: 1. There is no catalyst and it can be quickly solidified. It can be sprayed on any curved surface, inclined plane and vertical plane, without sagging. The 5-second gel can meet the walking intensity in one minute. 2. It is insensitive to humidity and temperature, and will not be disturbed by ambient temperature and humidity during operation. (It can be operated on the ice surface; it can be operated at - 28 ℃; it can be solidified in the freezer) 3. It has two components, solid content, and no volatile organic compounds (VOC), which is environmentally friendly. 4. Polyurea can be sprayed or poured according to 1:1 volume ratio, and the thickness of one operation can range from hundreds of microns to several centimeters, which overcomes the shortcomings of repeated construction in the past. 5. Excellent physical properties of polyurea, such as tensile strength, elongation, flexibility, wear resistance, corrosion resistance, etc. Polyurea has excellent thermal stability, can be used for a long time at 120 ℃, and can withstand a short time thermal shock at 350 ℃. 6. Like ordinary coatings, polyurea can add various colors and dyes to make products of different colors. 7. Polyurea formulation system can be adjusted at will, and the touch can range from soft rubber to hard elastomer. 8. The polyurea prototype has good reproducibility, continuous and compact coating, no joints, no holes, beautiful and practical. 9. The complete set of equipment is used for convenient operation and speed; One operation can meet the design thickness standard and get rid of the shortcomings of many operations in the past.
Polyurea is a special coating. Polyurea is a polymer formed by the reaction of isocyanate and polyol, which has good weather resistance, chemical corrosion resistance and wear resistance. It is often used to coat metal, concrete, wood and other surfaces to provide protection and decoration effects. Polyurea coatings have high durability and pollution resistance, and are commonly used in industrial facilities, bridges, parking lots and other places.
