company news about Waterborne paint coating technology and characteristics

Waterborne paint coating The common construction technology of waterborne paint coating is divided into roll coating, brush coating, spray coating, dip coating, spray coating and other methods. Coating refers to the construction process of pouring paint on the workpiece to be coated through the nozzle. With the development of industrial automation, an automatic coating production line is formed, which means that the paint is stored in a high slot, drizzled above the nozzle or narrow slit bin, and showered on the coated material on the conveyor belt in a curtain shape to form a uniform coating film. Spray coating is generally suitable for the coating of plate and ribbon materials such as steel plates in mass production. Compared with dip coating, the scope of applicable workpieces is wider, for lighter parts or hollow workpieces, dip coating is easy to float, the use of spray coating is a good solution to such problems, with the continuous advancement of green manufacturing, green development, environmental protection departments for coating enterprises VOC emissions requirements are getting higher and higher, and the heat sink 'electrical housing, internal combustion engine housing and other irregular shape, When spraying, it is necessary to spray many times, multi-directional spraying, resulting in a large amount of waste water, waste gas, VOC and other harmful substances, which do not meet the discharge standards. Waterborne paint coating process features: green environmental protection, paint comprehensive utilization rate is high, effectively reduce VOC emissions, waste gas waste water generation. Widely used in mechanical and electrical equipment, generators, fans, vehicle parts and other fields. The coating process has high production efficiency and is suitable for mass flow operation. The coating effect is good, the coating thickness can be adjusted, the coating surface is more uniform, and the special substrate such as aluminum and stainless steel has good adhesion and protection.
