Working Principle of Automatic Mortar Jetting Machines
The main working component of an Automatic Mortar Jetting Machine is a double-acting pneumatic hydraulic booster pump, and the reversing mechanism is a specially designed pilot-operated, fully air-controlled gas distribution reversing device. When compressed air enters the system, the piston moves to the upper or lower end of the cylinder, triggering the upper or lower pilot valve. The control airflow instantly activates the valve reversing device, causing the piston of the air motor to perform stable and continuous reciprocating motion.
The piston is rigidly connected to the plunger in the mortar pump, and since the piston's area is larger than the plunger's area, the mortar is pressurized. The pressurized mortar is conveyed to the airless spray nozzle through a high-pressure hose. At the nozzle, the hydraulic pressure is instantly released, atomizing the mortar and spraying it onto the surface to be coated, forming a smooth and uniform layer.
Advantages of Automatic Mortar Jetting Machines
A. Superior Coating Quality
-
The mortar layer produced by the machine is smooth and fine, with no brush or roller marks.
-
The machine atomizes the mortar into fine particles, distributing it evenly across the surface.
-
This results in a dense and uniform coating layer, unmatched by traditional brushing or rolling methods.
B. High Efficiency
-
The machine can achieve a spraying efficiency of 200-500 square meters per hour, significantly surpassing manual application methods by 10-15 times.
C. Enhanced Adhesion and Durability
-
The high-pressure jet mechanism provides the atomized mortar particles with powerful kinetic energy.
-
This enables the particles to penetrate the surface pores, creating a denser layer and improving the mechanical bonding between the mortar and the substrate.
-
The enhanced adhesion ensures a longer lifespan for the mortar coating.
D. Uniform Thickness and High Material Utilization
-
Manual methods often result in uneven thickness (30-250 micrometers) and low material utilization.
-
In contrast, the Automatic Mortar Jetting Machine ensures a uniform thickness of 30 micrometers, optimizing material usage and reducing waste.
Conclusion
The Automatic Mortar Jetting Machine revolutionizes traditional coating methods by offering superior quality, high efficiency, enhanced durability, and optimal material utilization. Its ability to deliver precise, consistent, and long-lasting coatings makes it an essential tool for modern construction projects.
