Spray - immersion type is generally when combined with a steel coating processes in, first thing to do is spray, then soak into the groove, the groove is sprayed after waiting again, all the spraying, immersion were the same groove liquid. This combination retains the high efficiency spray painting steel prices, improve the overall processing speed, but also with immersion process, so that all parts of the workpiece can be effectively addressed. Therefore, combining immersion spray pre-treatment process that is able to handle relatively short period of time to complete, the device takes up relatively little space at the same time and be satisfied with the treatment effect. Currently at home and abroad, for the higher pre-treatment requirements of the automotive industry, generally tend to take the shower - soaking binding mode. Currently, air atomizing spray guns were powered by an external hybrid atomization. Air atomizing spray nozzle provides the primary method. Through space located between fluid nozzle and hood (ie central atomization orifice) to complete the major standard steel spray atomization air column and paint flow from the space complement each other to produce a first-class paint atomization. At this stage, the choice of appropriate diameter of the nozzle is very important, and the size of the nozzle diameter is usually from the viscosity of the coating, the spray coating performance, desired coating thickness and size and other parameters to be spraying the area to decide. 3 o / E / i3 V * a * t6 z1 C and air assisted atomization nozzle hole angle is the same, and is located hood face, these holes has two effects: First, the graphic does not expand too quickly in the spray, and holding the nozzle end surface cleaning hood, such as the presence or absence of clogging the lowest steel spray will cause eddy currents or reflux; Second, the high velocity atomizing coating is particularly effective in the second stage which produces atomized coating; hood fan control airflow fan-shaped hole provides a graphical, none of these fan control air jet hole, atomizing air will be round instead of oval. Stomata number and size of the gun on the hood is in line with the overall design of the gun, and it can not be judged good or bad based on atomizing spray gun number and size of pores. ;] 4 r; F. n% l high quality steel spraying sand _ _ hung steel hardware appliances spraying spraying by Dongguan City, Sha Hong Hardware Electric Co.
