The internal and external painting treatment of the valve is an important part of its manufacturing process, which not only helps to improve the corrosion resistance and durability of the valve, but also enhances its aesthetic appearance. The following are some key points about the spray painting of German indicated stem gate valves:
1. Surface Preparation: Before painting, the inner and outer surfaces of the valve need to be thoroughly cleaned and pre treated to ensure the adhesion of the paint layer. This usually includes removing oil stains, rust, and other impurities.
2. Primer application: Before painting, a layer of primer is usually sprayed to provide additional anti-corrosion protection and a good foundation for the topcoat.
3. * * Topcoat Selection * *: The selection of topcoat should take into account the operating environment and durability requirements of the valve. Common types of topcoats include epoxy resin paint, polyurethane paint, etc., which have good anti-corrosion performance and weather resistance.
4. Spray coating process: The spray coating process requires precise control to ensure the uniformity and thickness of the coating. During the spraying process, attention should be paid to the temperature and humidity of the environment to ensure the curing effect of the paint layer.
5. Coating thickness: The thickness of the coating should comply with specific standards or user requirements, and the thickness of the inner and outer coatings may vary to meet different protection needs.
6. * * Color Code *: According to the JB/T106-2005 "Valve Marking and Identification Painting" standard, different valve materials may have different color codes. For example, carbon steel valves are typically painted gray, while stainless steel valves may not be painted or painted sky blue.
7. Inspection and Testing: After painting is completed, the valve needs to be inspected and tested to ensure that the quality of the coating meets the requirements.
8. * * User Requirements * *: In some cases, users may have specific painting requirements, such as specific colors or coating types, and manufacturers should customize according to user requirements.
Please note that the color of the spray paint cannot always reliably distinguish the type or material of the valve. Therefore, a more reliable method is to print or cast material markings on the valve body. When selecting a German indicated stem gate valve, reference should be made to the specific technical specifications provided by the manufacturer and the actual application needs of the user.
