The advantages of PVC film (non-drip film) are: (1) After covering, the water droplets accumulated on the inner surface of the greenhouse film can flow along the slope to the corner of the greenhouse, which has good water permeability and low humidity in the greenhouse, which can reduce the difference The occurrence of the disease. (2) The temperature in the greenhouse is 4 to 5 degrees higher than the temperature of the dripping film, which is conducive to safe overwintering and faster growth of greenhouse vegetables.

    The essence of the serous film is a polyethylene polyethylene (PE) long-life film (commonly known as grouting dry film) filled with a layer of grout in the inner layer to achieve the function of defogging and dripping. It is processed on the basis of the original PE film. The inner surface of the polyethylene film is treated with a mist eliminator. Therefore, the treated polyethylene film is tightly attached to the inner wall of the polyethylene film, and a protective layer is formed on the inner surface of the polyethylene film. Once the moisture in the shed comes into contact with the inner wall of the PE film, it will form a layer of water film, and then flow along the slope of the shed due to its own gravity, so as to achieve the effect of eliminating fog and dripping water.

    The special film for breeding is a material with white outside and black inside, mainly used in summer and autumn. When covering, the white side is facing upwards, which has strong light reflection ability. The black film prevents light from passing through and plays a role of shading and cooling. The temperature in the shed is much lower than that covered by other tarps and films.

    No matter what kind of agricultural film used in the greenhouse, it has a useful life. However, in actual production, due to the influence of high temperature, strong light and other factors, the aging rate of the greenhouse double film is relatively fast. Once the operation is not careful, it is easy to accelerate its aging and damage. So what problems should be paid attention to in the use and maintenance?

    Many people think that the thicker the plastic film, the better the insulation. In fact, this understanding is wrong. Let us first understand the thermal insulation principle of plastic film: plastic film divides the space into a separate enclosed space and saves heat to avoid heat exchange inside and outside the boundary. Where does the heat in the silver and black mulch come from? Next, Qingzhou Luhong Plastic Co., Ltd. will share this knowledge with you.
