Preparation and application of anti-fog coating——ultrasonic spraying process

classify:Ultrasonic spray coating

1. Medical and scientific research fields

·Medical equipment: endoscopes, surgical microscope lenses, ventilator masks, protective glasses, etc., to prevent water vapor from affecting the field of vision and ensure the accuracy of the surgical or diagnostic process.

·Laboratory equipment: culture dish observation windows, spectrometer lenses, microscope slides, etc., to prevent condensed water from interfering with experimental data collection.


2. Automobile and transportation fields

·In-vehicle equipment: car rearview mirrors, windshields, dashboard displays, to improve driving safety in rainy days or temperature difference environments; anti-fog for in-vehicle cameras (such as reversing images) to ensure clear road conditions.

·Rail transportation: high-speed rail windows, subway screen doors, aircraft windows, etc., to prevent fogging due to temperature differences during high-speed driving and ensure passenger vision and safety.


3. Consumer electronics and optical equipment

·Electronic screens: Displays of mobile phones, tablets, and smart watches to avoid blurring caused by fingerprints or water vapor; VR/AR glasses lenses to improve the clarity of the immersive experience.

Optical instruments: Camera lenses, telescopes, and surveillance cameras, to prevent lens fogging caused by outdoor environments (such as humidity, rain, and snow) to ensure image quality.


Ultrasonic spraying



Advantages of ultrasonic spraying technology:

1. The coating has higher uniformity and accuracy, and the anti-fog effect is more stable. It is especially suitable for precision optical components (such as lenses and display screens), ensuring consistent light transmittance and no visual blur.

2. The material utilization rate is significantly improved. The advantage of ultrasonic spraying is that the atomized particles are controlled by the vibration of the ultrasonic nozzle, the spraying range is accurately controllable, and the material waste rate can be reduced to less than 10%, which is especially suitable for expensive solutions (such as coatings containing nanomaterials and catalyst materials).

3. The coating thickness is highly controllable, and the coating thickness control from nanometer to micrometer level can be achieved to meet the needs of different scenarios (such as ultra-thin optical lenses vs thick industrial glass).
