Description

technical field [0001] The invention relates to the field of heating or cooling systems used for surface coating of metal materials, in particular to a cold-heat collinear cold-rolled color coating paint temperature automatic control device and a use method thereof. Background technique [0002] Maintaining a suitable and stable coating viscosity on the paint pan and coating roller of the coating machine is very important for maintaining uniform film thickness, surface quality, and stable process parameters of the product. It is an important process parameter for cold-rolled color coating production. [0003] Like all liquid media, the coatings used in cold-rolled color coating production also have significant viscosity-temperature change characteristics. When the temperature of the coating is lower than 20°C, the viscosity increases sharply as the temperature drops; when the temperature of the coating is higher than 30°C, Viscosity decreases slightly with increasing tempera...

Problems solved by technology

[0005] At present, the color coating unit adjusts the viscosity of the paint by adding diluent manually, which means that the viscosity of the paint cannot be precisely controlled, and a large amount of diluent is consumed excessively, which is also not conducive to the surface quality control of color coated products.

[0006] In addition, the thinner is a highly volatile, highly flammable, and highly toxic liquid. The large amount of thinner used in color coating production is not conducive to the occupational health of the enterprise and the coating room.
