powder coating booth new breakthroughs experienced corona charging gun voltage charging, current charge, the total energy control charging (T.E.C) several stages. The first two charging method is limited to the spray of the workpiece metal parts, and the use of “TEC total energy control charging” technology (TOTALENERGYCONTROL) broke through the above limitations. The main technical spray gun and that when the workpiece (contact point) when the change in the distance can be adjusted automatically to maintain the total current and voltage of the charging energy to effectively control the amount of charge powder, to ensure the efficiency of the powder.
Oxygen – acetylene flame metal powder powder coating equipment, oxygen – acetylene flame spraying metal powder technology is currently in the country to promote the application range is very wide, almost all large companies regard it as a means to repair old waste. Shanghai, Jiangsu, Sichuan, Wuhan and other places have been developed and produced a variety of models of spray, spray gun, spray units have been widely used service. Shanghai powder coating machine Machinery Factory recently in the original qht-7 base / h to improve flame gun, using two sets of nozzles, using two heat sources: the oxygen – acetylene flame and oxygen – liquefied petroleum gas (domestic bottled). The use of bottled liquefied petroleum gas for combustible gases, can greatly reduce the cost and spraying operations for greater convenience.
HVOF powder coating system, currently imported from abroad HVOF device (hvof), (hvaf) and supersonic plasma spraying equipment, which is characterized by high flying speed of particles, the coating and the substrate with high strength, low porosity, these devices have been in aerospace, aviation, metallurgy, chemical and power industries play an important role. However, these expensive imported equipment and fuel (propane, propylene) is not easy to spread, for the above, combined with China’s national conditions, Sichuan Changcheng Institute successfully developed coating technology for heat oxyacetylene flame speed paint line.
powder coating gun, Institute of Aerospace Corporation six hundred twenty-one started to develop from the 1960s, has placed a complete gas explosion spraying devices for aerospace, aviation and other military departments of many high-density high-quality spray coating equipment has reached or close to the level of similar foreign products. Beijing Great Wall Titanium cooperation with Ukraine in recent years, the company established a joint venture Beijing titanium New Material Co., Ltd., introduced the explosion spraying equipment manufacturing technology in Ukraine, is now able to produce a three-dimensional computer-controlled walking mechanism powder coating line spraying equipment, in addition to domestic-oriented users, has been sold to the United States and Taiwan and other regions.
powder coating booth high velocity arc spraying device, due to the combination of high intensity arc spraying, low energy consumption, low cost, so this equipment in the country in recent years, more and more people attach importance to and actively using, especially in a large area of ??the steel structure long-term protection works and power station boiler tubes hot corrosion plays an important role. On the basis of the general arc spraying, the national engineering centers and research facilities Armored Force Engineering Institute, Xi’an Second Artillery Engineering College also recently successfully developed a powder coating oven arc spray gun, air speeds of up to 600m / s or more, the coating bond strength, porosity and many other indicators are better than ordinary arc spraying, is currently being further popularized.
