MC-16 Powder Friction Spray Gun Friction type spraying method is to use the powder through the friction tube at high speed so that the powder is charged due to friction, this type of coating equipment is composed of a powder storage barrel, powder pump control host. This type of coating equipment is composed of powder storage barrel, powder pump control host and spray gun. This type of coating equipment is composed of powder storage barrel, powder pump control host and spray gun, this type of equipment is charged by friction of powder itself, so it does not need power supply and electrostatic generator to produce high voltage or forced powder. This type of equipment does not need power supply and electrostatic generator to produce high voltage or force the powder to be charged, so there is no electrode, and the spray gun is not connected with the workpiece. There is no electrode, and no strong electrostatic field is generated between the spray gun and the workpiece when the coating operation is carried out, and this kind of independent small electrostatic field is very weak. This small electrostatic field strength is very weak, can only be called a weak electric field, and each paint particles are positively charged. Advantages of the friction-generated spraying method: Faraday effect Powder easily enters into deep recesses of the workpiece, and there is no possibility of automation of dead corners and over-thickness of edges. Powder easily penetrates into deep holes, corners, and narrow grooves, enabling unmanned powder coating that does not require manual repair. Uniformity of coating No Laddie effect, no repulsive phenomenon, and ultra-thick coating can be done up to 400 microns in a single spraying. For some powders, film thicknesses of 30 microns or less can be achieved, and multiple choices of nozzles are available. Orange Peel Weak high-pressure, uniform powder cloud, uniform multi-finger spraying width, the same powder with the traditional electrostatic spraying method will produce orange peel, but not with the friction-generated electricity coating method.               Electrostatic field Each charged powder foam generates a weak electric field, through the air pointing to blow and stick the powder foam to the designated point, the film thickness of the inside and outside of the concave and corners is consistent, and it can save the powder foam by 20-40%. Multi-layer coating Since there is no anti-repulsion phenomenon, it is possible to do multi-layer coating without pinholes or craters under the requirement of heavy corrosion protection. Various applications The automatic spray gun is used with various spray nozzles to apply to various coating jobs with different requirements. Foam output Friction-generated electric spraying method has a smaller amount of foam output than the traditional high-pressure electric spraying method. Although the amount of foam output is smaller, the coating efficiency is higher, the output is unaffected, the load on the recovery system can be greatly reduced, and the energy consumption and maintenance costs are low. Advantages of friction electrostatic guns: Low friction, low running cost New charging method tube wall internal pressure and temperature is small, tube wall friction is less, parts replacement is also cheap, the user has the ability to replace their own. Atomization accelerated air In the body of the gun to increase an assist in atomizing and accelerating the powder foam, so that it excites the powder foam to release positively charged electrons, and depending on the need to send the charged powder to be coated at different places. Interchangeability Most of the parts are interchangeable with the old automatic electrostatic friction gun to increase its economy. Operability Spray gun design, simple operation, no need for advanced skills, general technical personnel to learn easy.
