Wholesale radiator powder coating

The main factors that affect the coating efficiency of wholesale radiator powder coating are the charging mode of coating equipment, the particle size distribution of powder, the temperature humidity of coating environment. Therefore, the suitable range of powder coating is 10-80 μ M. The relationship between particle size coating efficiency is as follows: the coating efficiency of particle diameter (μ m) above 150 is 35.0, 150-100 is 35-60, coating efficiency (%) 100-74 is 60-70, 74-20 is 70-90. Therefore, relative to the weight of the particles, the electrostatic force increases with the decrease of the particle diameter, the particle size is 36-100 μ m, 150-400 mesh powder can completely adhere to the cold coating, the larger particles (74-177 μ MC, 80-200 mesh) may fall the coating after spraying. The particle size of epoxy resin is 20-100 μ m, the standard rope of balanced particle size distribution should be 10-80 μ m, the lower limit of fineness is less than 10% below 10 μ m, particles below 60 μ m are less than 60%, it is suitable to form sharp particle size distribution of 20-50 μ M. because the powder below 20 μ m is easy to fly, the coating loss is more.
