Film Manufacturing
The manufacturing process of diamond-like resistive film involves technologies such as Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD).During the process, the film is created on a substrate, which can be made of various materials, including glass, metal, or plastic. However, for our heaters, we have chosen ceramic granite as the preferred material.The film has a minimal thickness and good adhesion to the substrate.
Technology of Vacuum Deposition of TiO2
The first step involves preparing the surface of the heater. The surface must be thoroughly cleaned of dust, oil, dirt, and other contaminants. This is crucial to ensure good adhesion between TiO2 and the heater surface.Prepared heaters and TiO2 material are loaded into a vacuum chamber used for the deposition process. In the vacuum chamber, a low-pressure environment is created to minimize the influence of atmospheric gases and dust on the deposition process.Inside the vacuum chamber, TiO2 is heated, causing its molecules to evaporate. After evaporation, TiO2 molecules deposit onto the surface of the heater, forming a thin layer. This process is known as deposition.During the deposition process, the thickness of the coating is closely monitored, ensuring precise control of the TiO2 layer's thickness. This is essential for achieving the desired properties and efficiency of the heater.After the TiO2 layer is applied, the heater's surface may undergo drying and fixation processes, such as exposure to ultraviolet light. This can expedite the photocatalytic action of TiO2.
