One. Attention should be paid to the installation of painted objects on the painting production line. Pre-dip test to design the hanging method of the hanger and the object on the coating production line to ensure that the workpiece is in a better position during dipping. The large plane of the object to be coated should be close to vertical, and the other planes are at an angle of 10°-40° with the horizontal, so that the remaining paint can flow out smoothly.

two. In order to prevent the solvent from spreading in the workshop and dust falling into the paint tank when painting on the painting production line, the dipping tank should be protected.

three. After the large objects are dipped in the coating production line, they should be sent to the drying room after the solvent is basically volatilized.

four. When painting, pay attention to the determination of the viscosity of the paint. The viscosity should be measured 1-2 times per shift. If the viscosity increases by more than 10% of the original viscosity, the solvent should be added in time. When adding solvent, the dip coating operation should be stopped. After stirring evenly, measure the viscosity, and then continue the operation.

Fives. The thickness of the paint film is mainly determined by the rate of object lifting on the coating line and the viscosity of the paint solution. After controlling the viscosity of the paint solution according to the above requirements, the coating production line should determine the appropriate lifting rate in accordance with the maximum speed of the paint film about 30um and according to different equipment. At this rate, the coated object is evenly lifted. The lifting rate is fast and the paint film is thin; the lifting rate is slow, and the paint film is thick and uneven.

six. During the dip coating operation on the coating production line, sometimes the thickness of the paint film being coated and the lower part of the paint film is different, especially on the lower edge of the coated object. In order to improve the decoration of the coating, use a brush to manually remove the excess accumulated paint drops when dipping in small batches, or use centrifugal force or electrostatic attraction equipment to remove these paint drops.

Seven. When dipping wooden parts in the coating production line, pay attention to the time not to be too long, so as to avoid the wood from inhaling excessive paint, resulting in slow drying and waste.

Eight. Strengthen ventilation equipment to prevent the harm of solvent vapor; pay attention to the arrangement of fire prevention measures and regularly inspect the coating production line.
