Spraying Photovoltaic Glass

Ultrasonic spraying machine enables the production of 1.1×2.2m photovoltaic glass and opens a new journey of efficient coating

In the booming photovoltaic industry, photovoltaic glass is the key protective and light-transmitting component of photovoltaic modules, and its performance is directly related to the power generation efficiency. With the increasing diversity of photovoltaic glass sizes, for photovoltaic glass with a width of 1.1 meters and a length of 2.2 meters, the traditional spraying process is prone to uneven coating and material waste when facing large-size substrates. The ultrasonic spraying machine has brought a new breakthrough in the coating process of photovoltaic glass of this specification with its innovative technology.

The ultrasonic spraying machine uses the principle of high-frequency ultrasonic vibration to convert the coating into uniform and fine droplets. When applied to the spraying of 1.1×2.2m photovoltaic glass, its unique advantages are fully demonstrated. First of all, in terms of coating uniformity, the ultrasonic spraying machine can make the coating droplets spread evenly on the glass surface through a precise atomization system. When the traditional spraying method is sprayed on a large area, it is very easy to have inconsistent coating thickness at the edge and center due to the limited coverage range and atomization effect of the spray gun. The droplet diameter of the ultrasonic sprayer can be precisely controlled at the micron level, which can ensure that every part of the 1.1×2.2-meter photovoltaic glass surface has a uniform coating thickness, effectively avoiding the loss of photovoltaic module power generation efficiency caused by differences in light transmittance.

Secondly, from the perspective of coating utilization, if the traditional spraying method is used in the coating process of the large-size photovoltaic glass of 1.1×2.2 meters, the waste of coating is relatively serious. The ultrasonic sprayer reduces the scattering and rebound of coatings in the air through precise atomization and directional spraying technology. It can intelligently adjust the spray flow and atomization intensity according to the glass size and coating requirements, and increase the coating utilization rate to more than 85%. Compared with the traditional spraying method, it greatly reduces the production cost. This is undoubtedly an important guarantee for enterprises that mass-produce 1.1×2.2-meter photovoltaic glass to reduce operating costs and enhance market competitiveness.

In terms of spraying efficiency, the ultrasonic sprayer is equipped with an efficient spraying system, which can achieve fast and uniform large-area spraying. Its unique nozzle design and motion trajectory planning can shorten the spraying time of 1.1×2.2m photovoltaic glass while ensuring the quality of the coating. At the same time, the equipment also has good compatibility and can be adapted to a variety of functional coatings. Whether it is an anti-reflection film that improves light transmittance or a protective film that enhances the anti-fouling and wear resistance of glass, it can be sprayed with high quality through the ultrasonic sprayer to meet the performance requirements of photovoltaic glass in different application scenarios.

In addition, the intelligent control system of the ultrasonic sprayer also brings convenience to the production of 1.1×2.2m photovoltaic glass. Operators can accurately set the spraying parameters and monitor the spraying process in real time through the human-computer interaction interface. The equipment also has fault warning and automatic calibration functions, which can promptly detect and solve problems that occur during the spraying process, ensure the stability and continuity of production, and effectively improve production efficiency and product qualification rate.

With the continuous improvement of the photovoltaic industry’s requirements for glass performance, the application of large-size photovoltaic glass such as 1.1×2.2m is becoming more and more extensive. Ultrasonic spraying machines have become an ideal choice for photovoltaic glass coating production due to their significant advantages in uniformity, coating utilization, spraying efficiency and intelligent control. In the future, with the continuous innovation of technology, ultrasonic spraying machines will further optimize their performance, inject strong impetus into the high-quality development of the photovoltaic glass industry, and help the photovoltaic industry move towards the goal of higher efficiency and lower cost.
