Water base paint is popular choice for coating industry, especially for automotive area where eco friendly is deeply concerned. From marketing report, over half traditional paint production are looking for water base solutions and doing A/B tests over different objects and various working environments. However, water base paint is a big difference to solvent solution for it's chemical structure, and it also has very different requirements to it's application system. Following we're going to point out few crucial parts we need pay attention to when configuring a water base paint spraying system. Spray booth A very basic device for any paint application, but water base paint have different requirements to it. The initial point is the booth material choice which has to be stainless steel (SUS304 suggested) to avoid rust…

Spray painting is logically a pretty easy job which seems to be hassle free for any people. As it's basically to trigger spray gun to send out liquid paint by pumping. However, in real working condition we always have to hire a professional technician at fruitful costs for guaranteed output painting quality. Why is this and what makes this seem-to-simple task costly? Paint spraying principle The basic logic of paint spraying is to atomize liquid paint then apply to object surface smoothly. The necessary tools include a spray gun, pressurized pot or pneumatic pump for paint supply and a compressor. Spray gun is moving above object surface with specific angles and speed to complete the finishing process. Spraying defective phenomenons Common problematic phenomenons such as following: Color difference - the…

Robot protective clothing covers are made to prevent damage and high maintenance costs due to contact with dust, paint, oil, heat, molten metal, as well as metal scrapings and liquids during operation in various working environments. Robot clothing and robot protective covers have been used to prevent component failure, allow robots to operate in a big range of conditions, and extend the operational life of the robots. In general, robot protective clothing covers are designed by the following scenes: 1- Heat Protection Robot Cover This kind robot is mainly used in welding, especially in casting industry where is high temperature operation. Thus, robot cover must be heat resistance to prevent heat destroy to robot components. This kind of cover is mainly produced by tinfoil and fiber material for flexible and…

Paintshop will make a big amount of waste air during operation. Based the current paint spraying technologies, the maximum paint application rate is about 60%. That means at least 40% paint will be extracted. If the paint booth provides up to 90% filtration capacity and save the solid particles inside booth tank, rest 10% is still hazard if we blow into atmosphere directly. Especially when the factory is close to a residential area, there're very strict extraction standards. Thus a proper treatmen solution is required for any paint shop construction. Waste paint air treatment or filtration is a complex system based the construction standards. Generally there're following stages for a complete clean filtration: water filtration - carbon filtration - VOC treatment - flame treatment. Water filtration - The primary and…

Automatic paint spraying is drived not only by a bare spray gun but also piping with backend pump system. The most popular selection of paint pump includes a pressure pot, diaphragm pump, gear pump and piston pump etc. A propriate choice will greatly help with our operation and reduce potential issues. In following section we will provide quick guidance on how to select among the different paint pumps to support our production requirements. Either diaphragm or gear pump or piston pump or even the pressure pot is widely used in painting industry, so what's the difference for each option? Let's describe using the most simple words and logic for quick understanding. Diaphragm pump - Diaphragm pumps feature a flat, diaphragm inside of a housing held together by screws. When pumping,…

Electrostatic spray gun is widely used for high end spraying. But it's not easy to have it working well while a good operation will improve the coating efficiency. Following we will provide a quick guide of electrostatic spray gun operation and tips of maintenance. Before spraying Electrostatic spray gun and it's related equipment should be cleaned and in normal working condition. Compressor is ready with air dryer and oil filter with safe connection to spraying equipment. Before we start spraying, we should inspect the following: if all cables and tubes are properly connected if the electrostatic generator is well grounded close the paint cycling valve then put the paint supply tube into supply drum workpiece must be conductive on conveyor To reach the desired atomization, we should set correct air…

Water base paint is the most eco friendly choice for modern coating solutions. However it's not just a simple replacing of paint to fit directly with existing painting line system. Some crucial parts has to be configured separately in order to follow its specific requirements. Here we introduce 3 most crucial parts of water base paint application. Paint Mixing & Piping Water is corrosive medium for metal. It will lead to equipment damage and generate metal ions, which will not only make the paint film yellow but also reduce its anti-corrosion ability. For this reason, the water base paint container and pipeline should be made of stainless steel and should be chemically passivated. Low shear type model should be selected for the paint mixing system, mixer and back pressure regulating…

PLC programming control over spray gun is modern choice of painting system configuration. With a central control panel by logical touch screen programming we can easily regulate spray guns by preset functions such as on/off, color changing and cleaning etc. All parameters can be saved in memory for quick application. The work principle: PLC program over action switch, fluid atomization, color switch and liquid level alert etc with digital display. HMI screen central operation over all programmable functions. Basic functions Move forward or continuous spraying FAN/CYL ratio control and spray gun on/off Automatic color change and cleaning (optional) Paint mixer speed control Advantages Single or multiple spray guns central control Up to 100 configurable properties for precise control Complete color change programming Complete fluid ratio control Flexible soft tube connection…
