Thermal spray processing company explains gas supersonic spraying for you

       Supersonic spraying is a new technology applied to general arc spraying. Ultrasonic spray coating has better performance than conventional arc spray coating. In recent years, it has been widely used in machinery and equipment, chemical industry, electric power, metallurgical industry and other manufacturing industries. Damage and erosion problems have a great impact on the safe and stable operation of the power plant, and have also produced good economic and social economic benefits for the power plant.



Ultrasonic spraying is to send two flocculated metal materials into the two conductive ports of the electrically isolated spray gun, and connect the two aspects of high current and low voltage respectively. When the wires are about to come into contact with each other, their faults cause isolation in an instant, and the electricity can reach a high temperature of over 5000°C, causing the ends of the wires to melt and be atomized by the compressed air running at a very high speed, and the airflow is about 2 times the speed of sound ( The droplet is driven by compressed air and sprayed onto the steel surface at supersonic speed (40 b250/s) to produce an arc spray coating. Compared with general arc spraying, ultrasonic spraying has a finer coating structure, higher density coating structure and higher fusion compressive strength.

The Sx-600 supersonic spraying machine is the basic development trend of the SX-500 arc spraying machine, which improves the growth rate of the swirl chamber in the spray gun structure. When the air is compressed through the Laval chamber, the speed of the cyclone can be significantly increased, facilitating the supersonic ejection of the atomized particles.

When HV spraying, the total flow of carbon dioxide and natural gas should be determined according to the old mechanical equipment rules to ensure that the gun flame flow reaches the overall planned output power level.



Various factors in the actual active production process can lead to uncertainty in the oxygen-gas share, which is the key to determining the final distribution of the coating. Theoretically, complete ignition of propane requires a ratio of oxygen to propane of 5:1 (C3H8+5O2=4H2O+3CO2), which is a neutral flame (ie, the molecular structure of oxygen and natural gas is depleted during ignition).



The organic chemistry key of HVSP cable was tested by chemical molecular statistical analysis method. The chemical molecular analysis method is a traditional raw material composition analysis method. According to the chemical molecular analysis method, the raw material can be analyzed and judged according to the element composition and proportion of the raw material.



The key technology of supersonic spraying in the manufacture of mechanical parts can significantly improve its performance and service life, meet the requirements of high quality, high efficiency, environmental protection and energy saving, save building materials, environmental protection, can be repaired and reused, resulting in excellent economic benefits .



There are many forms of supersonic spraying, such as the choice of vulcanized rubber wheels for steel pipe or high-pressure hose spray painting, the choice of rigid ring separation methods, or the choice of dry brush spraying, and the characteristics of its performance can be adjusted according to the specific application situation. Rocket launches and space stations must guarantee such conditions.



Model selection criteria for thermal spray treatment equipment Main use: To be able to consider the mechanical equipment of water, electricity, steam and organic compounds of the generator set, it is necessary to ensure the quality of various aluminum and metal surface treatment machinery and equipment and paint, and other applications Mechanical equipment removes, removes and removes pests from the natural environment and the natural environment.



Molybdenum nitride, molybdenum dioxide and molybdenum nitride are indispensable mineral preservatives, and covering raw materials are also indispensable, which can have a certain practical effect of anti-corrosion.
