The main purpose of polyurea is to be used as anti-corrosion and waterproof material. Polyurea is an elastomer material formed by the reaction of isocyanate component and amino compound component. It is divided into pure polyurea and semi-polyurea, and their properties are different. The most basic characteristics of polyurea are anti-corrosion, waterproof, wear-resistant and so on.

Polyurea spraying machine can be applied to building roofs, tunnels, subways, roadbed waterproofing, foam film and TV props production, internal and external anticorrosion of pipelines, auxiliary cofferdam works, anticorrosion of storage tanks and chemical storage tanks, pipeline coating, desalination tanks , Waterproofing and anti-corrosion of pools, wear of chemical mines, fenders and buoyancy materials, waterproofing of basements, anti-corrosion of desulfurization towers, anti-corrosion of valves, waterproof and anti-corrosion of roofs, anti-corrosion of storage tanks, marine anti-corrosion, tunnel waterproof, bridge anti-corrosion , Anti-corrosion of prop production, anti-corrosion of fenders, anti-corrosion of sewage treatment plants, anti-corrosion of water storage tanks, anti-corrosion of seawater desalination tanks, etc.

In anti-corrosion and waterproof, it can be used in industrial maintenance, tunnels, subways, roadbed waterproofing, foam film and television prop production, pipeline anti-corrosion, auxiliary cofferdam works, storage tanks, pipeline coatings, demineralized water tanks, wastewater treatment, fender and buoyancy materials, roof waterproofing, basement waterproofing, etc.

The polyurea spraying machine includes the main engine, spray gun, feed pump, feed pipe, A part, R part, heating hose and many other parts, which must be connected reasonably to ensure the smooth completion of the spraying operation. The working principle of the polyurea spraying machine is to transfer the AB two-component polyurea coating to the inside of the machine through two lift pumps, heat it independently and efficiently, and then atomize it by ultra-high pressure spraying.

Advantages of polyurea spraying:
1. Fast curing: It can be sprayed on any curved surface, inclined surface, vertical surface and inverted top surface without sagging
2. Insensitive: not affected by ambient temperature and humidity during construction
3. High mechanical properties: high tensile strength, wear resistance, corrosion resistance, puncture resistance, aging resistance, good flexibility, etc.
4. Good weather resistance: long-term outdoor use without chalking, cracking, or falling off
5. Various effects: the coating has no joints as a whole, and can spray fine corrugated hemp surface effect; the color is adjustable and endowed with different colors
6. Cold and heat resistance: It can be used for a long time in the temperature range of -40℃—+150℃.
