Spraying Machine operation is mainly the operation use problem of the spray gun. The improper use of the spray gun can cause coating coating defects. The coating coating defects mainly manifest in three aspects: First, the coating is uneven, mainly as There are joint marks, inconsistent coating colors, and poor coating smoothness. Spraying Machineuc捕鱼大闹天宫3 has a small investment and a large profit. If every day (multi-function speed control) spraying equipment is sprayed 1000m2, according to the average market price of 4 yuan per m2, the worker's salary is about 500 yuan, and each device can make a profit of 3000 per day. Yuan, except for other factors, the annual income is more than 500,000 yuan. The Spraying Machine is easy to operate, does not require scaffolding, does not require mobile equipment, and does not need to be repaired. The yin and yang angles and the top plate can be sprayed freely, shortening the construction period, improving the progress, and saving the cost of the frame material. Second, the coating is too thick, mainly characterized by sag phenomenon, the surface of the coating is dry and the deep layer is not dry, and the coating crust phenomenon occurs. Third, the coating is too thin; the main performance is that after the conventional coating is applied, the coating does not reach the required thickness. There are three main issues to be aware of when using the spray gun.

1.Gun distance

The distance between the spray nozzle of the Spraying Machineuc捕鱼大闹天宫3 and the surface of the object to be coated is called the gun distance, and the gun distance is preferably 300~400mm. Spraying Machine manufacturers should finish the remaining materials in the hopper, and fill enough water in the hopper, clean the hopper, and pump it out, clean the hose and nozzle until the pump is full of water, so as to avoid the residual material in the hose. Coagulation, plugging hoses and nozzles. The gun distance is too small, the spraying pressure is too large, the recoil force is also large, the coating unevenness is easy to occur, and the spray width (the width of the fan surface) is small, so that the coated object is excessively sprayed too much, and the coating film is too thick. If the gun distance is too large, the spray pressure loss is large, the paint is easily lost, and the spray width is too large, so that the local spray of the coated object is too small, and the coating film does not reach the thickness requirement.

2.Spraying fan angle

uc捕鱼大闹天宫3 The spray fan surface and the surface to be coated should be perpendicular to each other. When the spray gun is manually operated, it should be noted that the spray width should not be too large each time, otherwise the angle of the spray fan surface will change significantly due to inconvenient operation, resulting in uneven coating.

3. Spray gun running direction and speed

uc捕鱼大闹天宫3 The direction of the spray gun should always be parallel to the surface of the object to be coated, perpendicular to the spray surface to ensure uniformity of the coating. The speed of the spray gun should be stable, preferably 300~400mm/s. The running speed is unstable, the coating thickness is not uniform, the running speed is too fast, the coating is too thin, and the slow coating is too thick.
