Three common treatments before painting


Chuangzhi Coating

Pre-treatment is the process of thoroughly cleaning the scales, rust, grease, dust and other dirt on the surface of the workpiece before painting, so that the coating powder is firmly bonded to the metal surface and has strong adhesion, so that the product can obtain high quality and prolong Product life.The three common processing methods before coating are divided into three types: immersion type, spray type and submersible type. The processing method is selected according to the workpiece and specific production requirements.

1. Snorkeling

The submersible treatment method is a method of conveying through a suspended chain to allow the workpiece to be immersed in the swimming pool and processed in the medicine liquid pool. It is suitable for the treatment of various complex shapes of objects, and has good effect and saves the amount of medicine.

2. Spray type

The spray type treatment method uses the spray principle to make the chemical liquid continuously work on the surface of the workpiece, which has strong work continuity and high efficiency. It is suitable for large-scale operation requirements, and has good processing effects. It is suitable for larger pipes, long pieces and structures. Simpler items and generally adopt elevated structure to save floor space.

3. Liquid immersion

The immersion liquid processing method is to use a crane to immerse the workpiece in the chemical liquid pool, and complete the treatment of the workpiece surface by physical and chemical methods. It is suitable for degreasing workpieces with complicated surfaces and severe rust, and installing trachea in the film tank. Depending on the specific conditions of the workpiece, the processing liquid can be stirred. A heating device can be installed in the liquid tank to improve processing efficiency, simple installation and low cost.
