Preparation of Low Emissivity Glass by Ultrasonic Spraying Method

Low-emissivity glass is sprayed on the glass layer of conductive film, so that the glass has visible light transmission, infrared light reflection of the characteristics of the glass with energy-saving effect.

The conductive film as a multi-functional inorganic materials, both low resistance and high visible light transmittance, but also has excellent film strength and chemical stability, the glass coated with a conductive film, you can get low Radiation glass.

At present, CHEERSONIC ultrasonic glass spray successfully prepared high quality low-e glass. Ultrasonic spraying equipment from the carrier module, carrier module, atomization module composed of three parts. The carrier gas module provides power support for the ultrasonic spray equipment and is capable of controlling the range and shape of the spray; the carrier module is a device for the ultrasonic spray equipment to store and transport the sprayed liquid; the atomizer module is the core module of the ultrasonic spray equipment responsible for the atomization of the liquid and scattered.

In the test, CHEERSONIC ultrasonic using SnCl4, H20, C2H5OH, NH4F formulated as a mixed solution, the prepared mixed solution was placed in ultrasonic spray equipment carrier module, open the ultrasonic generator control system, resulting in atomization, adjusting the carrier gas The module, which controls the flow rate and direction of the atomized spray, can be sprayed on the glass substrate. The general spraying time can be 10-20 minutes, because the time is too long will affect the light transmittance, the time is too short, the prepared film will be incomplete.

Experiments show that CHEERSONIC ultrasonic glass spraying equipment to prepare high-quality SnO2: F thin-film glass. The instrument test results show that: the visible light transmittance of 85%, the infrared cut-off wavelength of 1800nm, the resistance of 2 trillion cubic centimeter per cubic centimeter, the average particle size of 50nm.
