1. What is PVD coating technology? Answer: PVD is the abbreviation of Physical Vapor Deposition in English, and it means "physical vapor deposition" in Chinese. It refers to the thin film preparation technology that uses physical methods to deposit materials on the workpiece to be plated under vacuum conditions. 2. What are the classifications of PVD technology? Are there any PVD coating machines? Answer: PVD (physical vapor deposition) technology is mainly divided into three categories, vacu... read more
In the case of normal operation of the machine tool, to start the machine, you must first open the water pipe, and you should always pay attention to the working water pressure. At the same time, ion bombardment and evaporation, special attention should be paid to the high-voltage wire connector, which should not be touched to prevent electric shock. Electron gun in coating, peripheral bell to aluminum. It is best to observe the window glass with lead glass, and you should wear gl... read more
Vacuum evaporation film is to heat the material to be evaporated to a certain temperature by resistance heating or electron beam and laser bombardment in an environment with a vacuum degree of not less than 10-2Pa, so that the thermal vibration energy of molecules or atoms in the material exceeds the surface. Therefore, a large number of molecules or atoms are evaporated or sublimated, and deposited directly on the substrate to form a thin film. Ion sputtering coating is to use the high motion o... read more
Normal working conditions of vacuum coating equipment 1. Ambient temperature: 10~30℃ 2. Relative humidity: not more than 70% 3. Cooling water inlet temperature: not higher than 25℃ 4. Cooling water quality: urban tap water or water of equivalent quality 5. Power supply voltage: 380V, three-phase 50Hz or 220V, single-phase 50Hz (depending on the needs of the electrical appliances used), the voltage fluctuation range is 342~399V or 198V~231V, and the frequency fluctuation range is 49~51Hz; 6. The ... read more
Commonly used coatings for vacuum plating include UV-curable coatings, acrylic coatings, alkyd resin coatings, epoxy resin coatings, and polyurethane coatings.(1) UV curing coating:UV-curable coatings are coatings that are cured by chemical action under the irradiation of ultraviolet light with a wavelength of 250~450nm. feature is:The coating does not need to be directly heated, as long as it cannot be cured by ultraviolet light, it can save energy, and the curing speed is fast, measured in min... read more
