Which method is better, spraying or roller coating, for waterborne fluorocarbon paint in Chongqing!

This question needs professionals to answer; Advantages of Keguan waterborne fluorocarbon paint spraying, spraying and roller coating. Spraying technology has high production efficiency, is suitable for manual operation and industrial automation production, and is the most widely used painting method for paints and coatings. The environment required for spraying operation requires a dust-free workshop, and the spraying equipment includes spray gun, spray booth, paint supply room, curing furnace/oven, spraying workpiece conveying equipment, defogging and waste water and waste gas treatment equipment.

Keguan waterborne fluorocarbon paint spraying is characterized by smooth surface and uniform film thickness, but the main problems in spraying are that the paint mist is highly dispersed and the solvent is volatile, which not only pollutes the environment, but also wastes paint and causes economic losses. Roller coating technology-roller coating is most suitable for large-scale painting and decoration of internal and external walls of buildings. Advantages and disadvantages of water-based fluorocarbon coating roller coating are as follows:

1, advantages of roller coating

High-speed automatic operation, fast coating speed and high production efficiency, the production speed is generally around 100mm/min, and the highest can reach 244 m/min; There is no paint mist and splash, and the coating efficiency is close to100%; Low-viscosity and high-viscosity coatings are suitable, and can be coated with various film thicknesses ranging from 3-5μm to 300-500 μ m, and the film thickness can be accurately controlled and uniform; Both sides can be brushed at the same time.

2, roller coating shortcomings

Only suitable for plane painting, not suitable for other shapes of painting objects; Because roll coater adopts a unified paint recycling system, the paint investment is large, which is not suitable for multi-variety and small batch production; If the coating process conditions are not properly controlled, the paint film is prone to roll marks; Because the coating is transferred to the surface of the coated object in the form of wet film on the roller surface, the solvent volatilizes quickly, and the viscosity of the coating is easy to change during the roller coating process.
