Greenhouse film plays a very important role in agricultural production, is basically every essential agricultural supplies, but many users and greenhouse film understanding is only limited to the level of plastic film, many people do not understand the basic principle of greenhouse film fog elimination, so that waste and will not use this phenomenon.

Farmers know that the agricultural greenhouse film than ordinary film transmittance, heat preservation, tensile and aging performance requirements are high. But when there is a layer of fog on the surface of the greenhouse film will affect its light transmittance and then affect the temperature and humidity in the greenhouse, these two factors are important reasons to affect the growth of crops, so the greenhouse film is very important for the growth of crops.

The function of greenhouse film antifogging agent is to remove the fog in the shed, the mechanism of the action of greenhouse film antifogging agent has a lot of assumptions, just two of the hypothesis of the mechanism to do a brief introduction: first is the theory of mist diffusability in the use of the drop agent in the greenhouse film, the surface of the agricultural film to form a water film. When the concentration of droplet on the surface of water film reaches the critical micelle concentration, it presents a regular arrangement. It is difficult for water vapor in the shed to penetrate into the water film through the densely arranged droplet layer, making water vapor free in the air and combining with dust in the air to form fog. Secondly, the water film thinning theory contains fluorine and silicon surfactants, which have more ability to reduce the surface tension than hydrocarbon surfactants.
