In clean room decoration, the selection and requirements of wall panels are crucial to maintaining a clean environment. First, the wall panels should have excellent airtightness to prevent airborne particles from entering the room. Second, the siding material should be corrosion and chemical resistant to common cleaning agents and maintenance practices. The surface should be flat, smooth and easy to clean to ensure no dust accumulation. Anti-static properties are also necessary to prevent static electricity from causing interference in clean environments. The purification board/salination board produced by Haimei Metal meets these requirements and can be used in clean room decoration and cold storage decoration.
