Process: spray pretreatment → → dry. Pretreatment: For the film adhesion, not falling, long-life coating equipment, must be preprocessed before spraying on the surface of the part. Different parts of the metal material pretreatment methods vary. Steel parts mainly, rust, phosphate and other treatment, commonly used cleansing liquid decontamination agent degreasing, descaling by mechanical or chemical spraying equipment spraying machine, the part is immersed in an acidic phosphate diluent (density 1.0 ~ 1.1 g / cm, pH = 1 ~ 3), both at the interface will react. Generating a dense phosphate coating on the part surface to improve the adhesion and corrosion strength of the film. And alloy parts mainly degreasing, oxide film processing, oil and steel the same method, by pickling to remove the oxide film, and then forming a conversion coating chemical conversion treatment electrostatic sprayer spraying equipment, do not ask if the part surface, conversion may not be performed. Spray: The coating of the variety, performance and different curing conditions, the coating process, the method is different. Paint with grease paint, natural resin, epoxy resin, phenol resin such as a dozen paint, to follow to the actual situation. Spraying methods are manual, automatic, electrostatic, electrophoresis equipment duster spraying a variety of ways, according to the part volume, shape and size and available equipment options. Drying: The coating performance is excellent, hard, wear-resistant, must wait until fully dry after use. Coating drying properties of the coating itself divided physically drying and chemical drying. Physical drying means drying solvent evaporation and melting and solidification; chemical drying means oxidation, thermal polymerization, catalytic polymerization, radiation polymerization drying. Users can choose according to the part shape, size, bulk and equipment. Practical for quick drying, evaporation of the solvent-based coatings are often used in heat-curable coatings or by natural drying or simply drying process can achieve the desired effect. Paint pre-treatment process: the members confirmed → → degreasing → washing → rust → washing → conditioning → phosphating → cold water washing → hot water washing → → → test under item into the next step of the coating surface treatment before painting preparatory work must be carried out, the surface of the debris can be removed: grease, moisture, rust, scale, surface sturdy old paint coating adhesion and other factors, the elimination of chemical corrosion PATHWAY reinforced metal surface corrosion force . Of course, this should clear up before the burr on the workpiece datum. Burr, pouring, onto the scene and other factors that affect the coating smooth and beautiful.
