Suzhou Liujin Machinery Equipment Co., LTD. Tell you what automatic spraying production line needs to pay attention to!

Suzhou Liujin Machinery Equipment Co., Ltd. tells you what are the precautions for automatic spraying production line!

With the rapid development of society, more and more enterprises are adopting automatic spraying production lines, so a series of problems have come, what matters should be paid attention to when using these automatic spraying production lines, and what measures should we take when there are problems? The following Suzhou Liujin Machinery Equipment Co., Ltd. for you to answer

First, the automatic spraying production line should pay attention to the installation and hanging of the painted objects. The installation and hanging mode of the hangers and objects on the automatic spraying production line should be designed by test dipping first to ensure that the objects are in the best position when dipping. The maximum plane of the coated material should be close to vertical, and the other planes should be at an Angle of 10°-40° with the horizontal, so that the coating surface of the remaining paint can flow smoothly.

Second, in order to prevent the diffusion of solvents in the workshop and dust falling into the paint tank when painting on the automatic spraying production line, the paint dip tank should be protected.

Third, after the large objects are dipped in the coating production line, the solvent should be basically volatilized before being sent to the drying room.

Fourth, the coating should continue to pay attention to the measurement of paint viscosity, each shift should be measured 1-2 times viscosity, if the viscosity increases more than 10% of the original viscosity, it should be timely added solvent. When adding solvent, the dipping operation should be stopped. After stirring evenly, determine the viscosity, and then continue the operation.

The thickness of the paint film is mainly determined by the rate of lifting of objects on the coating production line and the viscosity of the paint solution. After controlling the viscosity of the paint liquid according to the above requirements, the painting production line should determine the appropriate lifting rate according to the maximum speed of the paint film of about 30um. Lift the painted object evenly at this rate. Fast lifting speed, thin paint film; The lifting rate is slow, and the paint film is thick and uneven.

6. During the dipping operation on the automatic spraying production line, sometimes there is a thickness difference between the coating and the lower part of the paint film, especially in the bottom edge of the coated material. In order to improve the decoration of the coating, the brush is used to manually remove excess accumulated paint droplets when dipping in a small batch, and these paint droplets can also be removed by centrifugal force or electrostatic gravity equipment.

7. When dipping wooden parts on the automatic spraying production line, pay attention to the time should not be too long, so as to avoid the wood inhaling excessive paint, resulting in slow drying and waste.

8. Strengthen ventilation equipment to prevent the harm of solvent vapor; Pay attention to the arrangement of fire protection and regular inspection

These are some matters that need attention for some automatic spraying lines popularized by Suzhou Liujin Machinery Equipment Co., LTD., hoping to help you
