Referring to prior art oil processing purposes remove the workpiece surface, dust, rust and corrosion and can generate a spray coating to increase adhesion "phosphate coating" on the surface. The main process steps: degreasing, rust, phosphate, passivation. After the pre-treatment of the workpiece surface is not only oil, rust, dust and spraying equipment conveyor, and original silver-white to form a layer on the surface of both rough shiny gray phosphate coating is not easy to rust, not only can increase the anti- spray layer adhesion-related equipment: pre-treatment tank (tank made of concrete, equal to that pretreatment step number); related materials (chemicals): sulfuric acid, hydrochloric acid, soda ash (Na2CO3), acidic addition to oil, phosphate solution passivation solution. Electrostatic spraying purpose spray powder coating evenly onto the surface of the workpiece, special jobs (including static shielding prone position) should use high-performance electrostatic spray machine to complete spraying. [1] process steps: electrostatic adsorption principle, on the surface of the workpiece a uniform layer of powder spray coating; powder falling through the recovery system recovering, after sieving can be reused. Related equipment: 1, electrostatic spray machine (electrostatic powder coating machine) 2 1 or more, with the powder booth recovery function (single station or duplex) 3, air compressors and air purifier (water filter) Related Materials: Powder Coating (coating materials, commonly known as "plastic powder," high light, light, different semi-matt, matt, sand grain, hammer, crack different color effect). Power components using special-pot wheel pot lifting gear lever, the machine housing is all-aluminum structure, with constant torque huge, low noise, maintenance-free characteristics. Japan's Mitsubishi inverter speed control unit with microprocessor control and IGBT technology, it has the reliability and flexibility. Complete protection is provided on the drive itself and motor protection. Control components using precision position sensor output coded signal to the circuit board for high-speed processing spraying equipment powder room, and thus the upper and lower pivot point lift stepless adjustment control. The control is simple, high precision, multi-segment multi-speed control, you can start at any position, up and down limit protection, high reliability, no stroke phenomenon. There are eight parts of mining machinery wheel hug square tube rails from the four directions, scroll up and down with a chain drive. This wheel made of special material recycling whirlwind spraying equipment, have a solid run smooth, and beautiful. Lift lift travel speed of 0.08 m / s to 0.8 m / sec adjustable stroke 2 m. Pulse control device using CMOS integrated circuit, a small size, long life, low power consumption, etc., but reliable, easy maintenance.
