With the development of the times, many feature-rich products have been created. I believe you have heard the term non-standard. These are mainly products manufactured in accordance with uniform industry standards and regulations. We not only have non-standard doors but also non-standard chains. The non-standard chain is a chain tailor-made according to the size of special mechanical gears. It does not meet the size standard defined by the national standard, but the quality is the same. Drive Chain Manufacturers introduced the painting requirements for non-standard chains:

1. The surface of the non-standard chain that has been sprayed and trusted should be immediately primed. The painting should be carried out in a clean and clean place. The ambient temperature should be above 5℃, the humidity should be below 85%, and the surface temperature of the workpiece should not exceed 60°C.

2. When there are no special requirements for each component, one primer (excluding maintenance primer) and two topcoats should be applied. Paint leakage is not allowed. The color of each layer of paint should be different, and the dry film thickness of each layer of paint should be 25~ 35 um, the total thickness of the paint dry film is not less than 75um.

3. The working surface of the non-standard chain smooth roller and roller can be coated with a layer of anti-rust paint or top paint, and the inner wall of the roller can be coated with rust paint.

4. The exposed processing mating surface should be coated with protective PU grease, and the exposed processing non-matching surface (excluding the frame body) should be coated with topcoat or primer, and the dry film thickness should be at least 35 feet.

5. After installation and debugging, the topcoat should be applied again, and the damaged parts during transportation and installation should be repaired before painting.

6. The coating of the non-standard chain primer and middle layer paint is not allowed to have defects such as pinholes, bubbles, cracks, shedding, sagging, and missing coating; the top paint must be uniform, bright and complete.
