Spraying ceramic paint on the inner wall of a stainless steel thermos cup is a common treatment method, which can improve the insulation performance and prevent problems such as scale. For best results, the following standards need to be followed:
1. Inner wall cleaning: Before spraying, the interior must be thoroughly cleaned. Any dirt or deposits may affect the adhesion and quality of the coating. Typically, specialized cleaners are used to clean interior surfaces, which should be rinsed thoroughly with clean water.
2. Surface treatment: Before coating construction, the surface of stainless steel materials must be specially treated to enhance the adhesion of the coating. This often involves using chemical solutions or etchants to create a bonding surface, or using equipment such as a sandblaster to roughen the surface.
3. Coating material selection: Choose ceramic paint suitable for the inner wall of stainless steel thermos cups. Generally, high-quality ceramic paint should have high adhesion, good wear resistance, corrosion resistance and high temperature resistance. In addition, consideration should also be given to whether it is safe when in contact with food and will not release harmful substances.
4. Spraying construction: Before spraying ceramic paint, the paint must be fully stirred to ensure its uniform consistency. Use professional spraying equipment and carry out construction at the appropriate temperature and humidity. Multiple layers of paint are generally used to increase coating thickness and durability.
5. Curing time: After the ceramic paint is sprayed, it needs to be cured at the appropriate temperature and humidity. This usually takes hours or days, depending on coating thickness and environmental conditions. It is important to ensure that the ceramic paint dries completely and forms a hard surface for best results.
