Coating apparatus for fabricating silica aerogel smart glazing continuously

摘要

PURPOSE: A coating apparatus for continuously fabricating silica aerogel smart glazing is provided to standardize technical standards including spraying pressure, spraying distance, and spraying conditions. CONSTITUTION: A coating apparatus is designed by a room type opening and closing coating mode. The diameter of a spraying nozzle is within 0.3mm, and the spraying nozzle uses an air spraying type nozzle. The particle size of a spraying aerosol solution is maintained between 50 and 100nm. The temperature of a coating room is maintained between 50 and 60 degrees Celsius. 40% of isopropyl alcohol is contained in the air in the coating room.
