Thermosetting powder coating equipment is an advanced coating technology, which is widely used in industrial manufacturing industry. This technology has many advantages, such as high efficiency, environmental protection, economy, durability and so on, so it is very popular. However, there will still be various failure problems in use, which need to be dealt with in time.
The use of thermosetting powder coating equipment needs to pay attention to some key operations, including the installation of equipment, power wiring, the commissioning of the spray gun, the pre-treatment of the coating item, and so on. To ensure the normal operation of the equipment, regular maintenance can be carried out, such as cleaning the painting room, replacing the nozzle, etc.
However, sometimes the equipment still fails, and professional troubleshooting is required according to the actual situation to avoid loss and misoperation. Here are some common faults and how to deal with them:
1. The spray gun does not spray powder
At this time, it is necessary to check whether the power supply is normal, whether the air pressure of the spray gun meets the requirements, and whether there is blockage or damage inside the spray gun.
2. Impurities appear in spraying
This may be due to the spray object is not cleaned, or the spray gun internal blockage caused by. For this situation, it is necessary to thoroughly clean the spray gun, painting room and other parts to ensure that it is clean and clear.
3. It is not easy to attach after spraying
Sometimes the effect of powder coating is not satisfactory, which may be due to improper pre-treatment, improper environmental factors such as temperature or humidity during the painting process, or inappropriate jet pressure of the spray gun. A suitable pre-treatment and operation process should be developed for each coating material, while keeping the temperature and humidity between the coatings appropriate to avoid interference factors such as oil, dust and so on.
In general, the use of thermosetting powder coating equipment needs to pay attention to operating specifications, timely maintenance of equipment, and timely treatment when problems are found. Powder coating equipment maintained in good condition can improve coating efficiency, reduce the failure rate, and provide more support for the development of the manufacturing industry.
