Surface treatments include: chemical pre-treatment surface shaping, degreasing, to embroider, phosphate, passivation. 1) Most plastic surface angle grinder to grind. 2) skimmed is degreased metal surface. The purpose is to increase the film adhesion, drying properties, rust resistance and service life. Degreasing solvent cleaning, alkaline cleaning. For small parts and other mainly alkali immersion degreasing. 3) rust: The aim is to make the film has strong adhesion, chemical and mechanical descaling rust points. Mechanical descaling also includes manual processing, blast treatment and flame treatment. Rust is mainly sand-blasting spray painting equipment, this our normal production blasting equipment, mainly used for large-scale structure rust, but for a small, thin-walled workpieces with caution to prevent workpiece deformation and fragmentation. So, for small pieces using chemical descaling ie acid rust. But after pickling rust environmental pollution is very serious gun powder coating equipment, the EPA's process need to be authenticated before they can be put into production. 4) oxide, phosphate, passivation: To improve the corrosion resistance of the workpiece and the strengthening of chemical rust paint film adhesion, leaving the metal surface to form a protective film, called chemical transformation of metal surfaces. Small parts for industrial machinery mainly phosphate treatment. Namely the use of phosphoric acid or phosphate processing manganese, the process of obtaining phosphate coating layer (phosphate coating) of iron, zinc, cadmium phosphate solution treated metal products. By phosphate treated metal surface, the film adhesion and corrosion resistance is greatly enhanced. Before the user coating work, to check all the paint varieties, models, specifications are in line with the provisions of the construction and technical conditions, if found substandard quality or deterioration of the paint is not able to use. Before using the paint for his performance to understand clearly, but also to understand how to properly use paint clear construction requirements according to their choice of paint to determine the appropriate painting tools. Many users do not know the proportion of the various components of the paint is different, generally paint after storage, there will be different levels of precipitation. Therefore, coating equipment gun before the paint coating must stir until completely homogeneous. If found patent leather or particles, use 80 to 120 mesh filter. Meanwhile, if you want to paint mixed use, then, must be used before the prescribed weight were mixed to homogeneity, if the mixing ratio error coating equipment spray equipment, will affect the drying properties and corrosion properties. In short, to remind the user, usually paint at the factory to be adjusted to a viscosity suitable for construction, it can not be diluted process. But in the temperature is too high or too low conditions, you can also add the appropriate amount of diluent to achieve the desired coating viscosity, but the amount of diluent should not normally exceed 5% by weight of the paint itself. Only know how to properly use paint to make us better construction effect has been improved construction quality has been improved.
