CNMC-65 pneumatic polyurethane foam spraying machine - Can be used for construction without heating!
In the field of polyurethane foam spraying, the portability, reliability and application precision of equipment have always been key considerations for contractors. The Winter CNMC-65 pneumatic polyurethane foam sprayer, with its core advantages of being ‘cost-effective, compact and requiring no preheating’, has become a practical choice for two-component polyurethane spraying, making it particularly suitable for small to medium-sized projects and mobile applications.
As an economical pneumatic equipment, the core configuration of CNMC-65 precisely meets the construction requirements: the single group flow rate is 7.5L/min, the pressure exchange ratio is 65:1. Under the drive of 0.3-0.6MPa compressed air, it can stably output power and is suitable for spraying operations of both high-viscosity and low-viscosity liquid materials; the stroke is 100mm, and the total weight of the machine is only 54kg. The compact body makes it easy to move flexibly in narrow spaces, and the transfer operation is more convenient; the mixing ratio is controlled at 1:1, and no additional adjustment is needed to meet the ratio requirements of two-component materials, ensuring the uniformity and stability of the foaming coating.
The design of not requiring heating is a major highlight of CNMC-65. Through the pneumatic atomization spraying technology, it can achieve stable temperature control without relying on external heating, ensuring the quality of the foaming coating. This design not only saves the cost and energy consumption of heating equipment, but also avoids coating defects caused by uneven heating. At the same time, it significantly improves the construction efficiency - it can start working immediately after startup, without waiting for heating, especially suitable for low-temperature environments or emergency construction scenarios.
In terms of mixing methods, CNMC-65 supports both in-gun mixing and out-of-gun mixing modes, which are suitable for different construction needs: In-gun mixing is achieved through the built-in mixing system of the spray gun, enabling the uniform mixing of A and B component liquids. The amount sprayed is exactly the amount mixed, eliminating waste in mixing and reducing equipment failure rates caused by curing; Out-of-gun mixing can quickly spray curing-type two-component liquid materials. The mixing ratio can be mechanically adjusted, flexibly adapting to the construction requirements of different materials. The construction party only needs to select the corresponding spray gun based on the spraying material and the scene.
With these advantages, CNMC-65 is widely used in various scenarios such as building insulation, waterproofing and anti-corrosion, and pipe coating: In the construction of building exterior insulation, it can quickly form a uniform foaming layer without heating, thereby improving the insulation effect; in pipeline anti-corrosion operations, the accurately mixed coating can effectively resist corrosion and extend the service life of the pipeline; for small-scale projects or mobile operations, its compact body and convenient operation have significantly reduced the construction threshold and cost.
