CNMC-E40 Electric Polyurea Spray Machine | Electric Drive, Stable High-Pressure Spraying

Polyurea spraying places strict requirements on mixing ratio accuracy, pressure stability, and equipment controllability. These factors play a critical role in the quality and durability of waterproofing and anti-corrosion projects. The CNMC-E40 Electric Polyurea Spray Machine features an electric drive system and an intelligent PLC control system, providing a reliable spraying solution for demanding polyurea applications. It is suitable for roof waterproofing, floor protection, tank corrosion protection, tunnel waterproofing, and other industrial coating projects.

The machine features a compact structure and a small footprint, making it easy to position and transport on construction sites. It can be installed in temporary site shelters, confined equipment rooms, and other areas where working space is limited, without occupying excessive construction space. Its advanced control module enables real-time operating data transmission, while the PLC display provides clear information about machine status and operating parameters. Operators can monitor working conditions and adjust settings conveniently through the control interface.

Compared with conventional pneumatic and hydraulic spraying equipment, the electric drive system provides stable and controllable spraying performance. The CNMC-E40 delivers an operating pressure of up to 23 MPa and maintains a precise 1:1 output ratio between the A and B components. Consistent material delivery and thorough mixing help reduce the risk of coating defects caused by improper proportioning or inadequate mixing, such as peeling and pinholes. The resulting polyurea coating offers a dense, flexible finish with reliable waterproofing and corrosion protection performance.

With an output flow rate ranging from 2 to 12 kg/min, the machine can accommodate different project requirements, from large-area continuous spraying to localized repairs. Its adjustable output capacity provides flexibility for contractors handling projects of different sizes and workloads.

For easier maintenance, the CNMC-E40 features a fault diagnosis function that displays error information through the control system. This allows operators to identify potential problems more efficiently, reducing unnecessary equipment disassembly and helping minimize downtime. The machine also supports a heated hose length of up to 90 meters, providing greater flexibility when working across large construction areas or at a distance from the main equipment.

The heating system is designed to maintain suitable material temperatures during operation. Two independent heaters, each rated at 3 kW, work together with the temperature-controlled heated hose to help maintain material fluidity, including in low-temperature working environments. Stable temperature management supports consistent material delivery and helps maintain coating quality throughout the spraying process.

The CNMC-E40 offers broad electrical compatibility, supporting 230V three-phase and 400V three-phase power supplies, with both 50 Hz and 60 Hz frequencies. This makes it suitable for a range of domestic and international construction environments. The machine has a total power rating of 12 kW, overall dimensions of 804 × 842 × 1230 mm, and a net weight of 280 kg. Its robust construction combines structural stability with practical mobility for on-site operation.

Whether used by anti-corrosion contractors, waterproofing teams, or professional companies specializing in polyurea applications, reliable equipment is essential for maintaining coating quality, controlling project costs, and meeting construction schedules. With its electric drive, intelligent PLC control, stable pressure output, and flexible heating configuration, the CNMC-E40 Electric Polyurea Spray Machine provides a practical solution for demanding polyurea spraying projects.
