??The greenhouses built by po film have two characteristics of thermal insulation and light transmission effect, so it is widely used in agriculture and animal husbandry level, as the cover of greenhouse crops in winter, the internal temperature of the greenhouse is generally higher than the outside, and the environmental humidity is not large, so the environmental temperature of the plastic film will be attached to another layer of high-density cat plague fine particles. When the sun shines on the surface of the po film, it will cause a diffuse reflection condition, so that the transmittance of the light source is greatly reduced.

??

Reduce the harm caused by fine particles, make full use of the greenhouse film and performance indicators, can produce infrared induction to the surface of the greenhouse film. Use plastic with high water absorption capacity. Make the plastic surface highly hydrophobic, even if condensed water, only produce large water droplets and quickly fall down.

po film is forbidden to dry or sunlight exposure before building greenhouses, wet is better. When on the shed, regardless of sunny days, rainy days, it should be early or at night to avoid the high-temperature link. In the shed with liquid on the side of the arch, do not reverse, after the shed is forbidden to DORA Shen, the greenhouse film is smooth and wrinkle-free, after the shed, at a faster rate before the drip-free film is dry, the shed surface is flattened and fixed.

In the process of use, the surface of the po film is highly hydrophilic, and the contact Angle to water is reduced, and water can produce thin contracted water on the surface, avoiding diffuse reflection.
