company news about Note on the use of powder coating machine

1. Check whether the air compressor air is clean before use, and ensure that the gas quality is free of oil, dry and moisture; Also check the cold dryer and filter regularly;

2. The air pressure entering the duster must be maintained at 0.5 to 0.7Mpa, which can not be lower than 0.5mpa (except for the experimental gun) when in use, if it is too low, the powder is small or no powder;

3. Check whether the flow of the powder barrel is normal during use: the powder keeps rolling and bubbling in the powder barrel, etc., and use the hand to reach into the powder and stir it back and forth, like water, easy and free, without any debris and powder pellets; If the fluidization is not good, it will cause uneven powder, powder spitting and other states;

4. When using the duster, it is necessary to check whether the grounding of the workpiece is good (refer to ensuring that the ground pile is embedded in the ground at a depth of more than 1.5 meters), the grounding resistance shall not be greater than 1 megohm, and the spreader shall be cleaned regularly;

5. The powder pump must be cleaned on time, and the powder pipe must be checked and replaced regularly, otherwise it will lead to small powder production, uneven powder production, powder vomiting and other conditions, which will seriously damage the empty precision parts of the powder supply pump, resulting in damage to the powder supply pump; Red and black quick insert filter cotton, under the premise of ensuring high-quality air supply, must be used and replaced according to the cycle;

6. The powder channel must be cleaned on time, and the powder pipe must be cleaned before work every day to prevent blockage, so as not to cause small powder and no powder;

7. The gas pipe must be cleaned on time, check whether the gas pipe is blocked at any time, and it should be cleaned in time, otherwise it will affect the powder state;

8. The needle and nozzle of the spray gun electrode must be cleaned on time to prevent blockage. The needle and nozzle shall be replaced according to actual wear, otherwise the product quality will be affected; Generally, the use time is longer, and the electrode needle protection block is generally replaced in 10 to 15 days;

9. When using the spray gun, the distance between the gun head and the workpiece must be appropriate, the distance between the manual spray gun head and the workpiece is recommended to be between 100mm and 200mm, and the di
