Oil removed before processing purposes technical reference surface, dirt, rust spraying equipment whirlwind recovered and the surface of a layer of anti-corrosion and can increase the spray coating adhesion "phosphate layer." The main process steps: degreasing, rust, phosphate, passivation. After the pre-treatment of the workpiece surface is not only oil, rust, dust fence spraying equipment, 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 adhesion plastic layer related equipment: pre-treatment tank (tank made of concrete, the number of steps equal to the number of pre-treatment); related materials (chemicals): sulfuric acid, hydrochloric acid, sodium carbonate (Na2CO3), acidic degreaser, phosphating 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). Now, with the automotive industry and coating industry continues to develop and constantly improve people's environmental awareness sprayer spraying equipment, governments and car companies began to gradually adopt environment-friendly coating materials, allowing harmful volatile paint produced during spraying emissions of substances meet environmental requirements. Therefore, automotive and industrial coatings forward high solidified, water-based, low VOC emissions of direction. The EU has proposed a car paint, decorative metal contained in the volatile VOC paints and varnishes in the amount of 50% reduction of legal amendments, for waterborne coatings VOC content per liter of control in 50g or less solvent coatings VOC content per liter control in less than 75g. Efficient tool for spraying paint technician is particularly important. HVLP / RP Environmental province paint / paint efficiently province K3 series of high load pressure fed paint spray gun, mainly with double diaphragm pump and pressure tank connection using spray coating equipment, has long produced high-load characteristics, is suitable for spraying production line, such as: automotive OEM coating line, a bus manufacturing plant, a large area of ??industrial painting and a large area of ??high-tech nano materials, such as spraying. Depending on the atomization technology best spray gun regulate pressure; the material flow to the maximum, such as paint discharge excessive, try not to be too forward needle, needle to avoid premature wear; held spray gun, the gun The hood should be sprayed with the surface of the workpiece is vertical; when its trajectory to keep the spray gun moving parallel to the surface, depending on the use of different guns, spraying distance is different; while spraying the entire arm moves through the workpiece surface, keeping the wrist straight, not an arc running track, in order to avoid coating color and coating thickness uneven; after each stroke start trigger spray gun trigger, the gun trigger is released before the end of each spray stroke; visual paint types, its spray pattern overlapping range of 1/3 ~ 1/2 range; depending on the type of paint is different from the speed gun is 30 ~ 50cm / s, in order to obtain optimum film thickness.
