Advantages and identification of anti-fog PC hollow sheet greenhouse
Ordinary PC hollow sheet, in the dry climate, the surface is prone to static electricity, adsorption of dust. And because the contact angle of common PC sun boards and water is generally 30-40 degrees, the water droplets on the surface of the board do not slide easily. In the drying process of water droplets, a large amount of dust in the air is adsorbed, and water marks are formed after drying. dirt. The surface of the board is difficult to clean, and the light transmittance of the board is seriously reduced, which affects the growth of the crop.
Anti-fog PC hollow sheet, in the production process, the outer surface of the sheet co-extruded a layer of 50μm high-tech special nano materials. To make it have the ability to self-cleaning on the basis of ensuring the original anti-ultraviolet ability. Special nano-materials can effectively reduce the generation of static electricity on the surface of the PC solar panel. The outer surface is not easy to get ash. Colleagues can change the contact angle between the outer surface of the panel and the water so that the outer surface of the panel has a super hydrophobic effect, and the contact angle between the water and the outer surface of the panel. More than 150 °, as if rolled on the lotus leaf, so that the dust attached to the outer surface, the dirt falls quickly with the water droplets gravity, take away the outer surface of dust and most of the dirt, leaving no traces of water. Keep the outer surface of the plate clean and high light transmittance for a long time. It is conducive to the growth of crops and reduces the daily maintenance costs of greenhouses.
Hilly anti-fog PC hollow sheet is coated on the inner surface of the plate with a special hydrophilic coating. This hydrophilic coating can increase the surface tension of the plate and reduce the contact angle between the water and the plate. The contact angle between the water drop and the surface is less than 5 °C, the condensate is spread on the inner surface of the plate to form a water film. The water film is in close contact with the plate, and it will leak into the drain along with the angle of leakage of the plate. The effect of the droplets on the growth of crops is reduced, and the plates maintain excellent light transmission. At the same time, Israel's unique anti-fog drop coating treatment technology makes the coating more durable and can effectively guarantee 10 years of anti-dropping effect.
