Equipment for the production of powder coatings is suitable for the processing of various types of powder coatings and can also achieve satisfactory results. However, many early Equipment for the production of powder coatings, domestic second-generation and third-generation advanced equipment are still being used by the majority of users. Its structure and performance are not so perfect. We mainly discuss some problems in the use of these devices with the majority of users.

1. Setting the temperature of the melting section
The Equipment for the production of powder coatings manufacturer tells you that in order to carry out the smelting, the ingredients must be heated up, especially the fusible matter in the ingredients must be completely melted as soon as possible, and kept at a certain temperature (that is, the set temperature), so that it becomes The various infusible substances in the components are coated and mixed with each other. Therefore, setting the temperature has two purposes. One is to melt the fusible substance as soon as possible, and the faster the time, the better, so that it can be placed in the barrel. The smaller the proportion of the length of the position, the longer the corresponding mixing time, which can improve the mixing effect; the second is to limit the temperature rise to a fixed value to start the cooling system to prevent solidification of the material.
The manufacturer of Equipment for the production of powder coatings tells you that the temperature of the material in the melting zone is the lowest, and the heat absorption is the main reason. The set temperature should be the highest. However, it is undesirable to set the lowest in the early manual because the screw speed is very low , The output is also low, the speed of the material passing through the barrel is very slow, and there is sufficient time for heating.
2. Setting the temperature of other working areas
The equipment for the production of powder coatings manufacturer tells you that the principle of setting the temperature of each zone in front of the melting zone is to gradually reduce, the lower the screw speed, the more the reduction, and the high-speed models for non-high-gloss powder processing should reduce or even not reduce.
3. Adjustment of working speed
The manufacturer of Equipment for the production of powder coatings tells you that after the motor starts smoothly, it should run at the rated speed as much as possible, and the main current should be kept at (90-95)% of its rated current value. The correct starting procedure is to first adjust the temperature of the melting zone to be higher than the softening point of the fusible material (10-20) ℃, as a starting setting, start the feeder when the balanced rise speed reaches (25-30) Hz after starting, and slowly increase At the same time, adjust the temperature setting value of the melting zone. When the main current is close to the rated value, the feeding speed will stop increasing; then the speed of the main motor will be increased to 35Hz, and then the feeder will be adjusted. Repeat the above operation, each time the main motor increases speed by about 5 Hz until the rated speed (50 or 60 Hz). The whole process must not be too fast. Sometimes the main current in the feeder may slightly exceed the rated value. It does not matter. After the main motor speeds up It will drop down immediately, but the feed rate must be reduced at the rated speed.
