In the process of building the greenhouse, the construction is carried out step by step. After the greenhouse bones are installed, covering materials will be selected for the greenhouse. Most farmers will choose to use plastic film, so how can they buy products that suit them? Next, Qingzhou Luhong Plastic Co., Ltd. will introduce the use ofLongevity non-drip filmI hope it will help you.
1. You need to understand that different types of plastic films should be used for different types of greenhouse structures. For example, in Beizhen greenhouses, PVC film should not be used because its transverse tie rods are located on the upper chord of the shed frame. Due to its large ductility, it is not easy to tighten, and the distance between the film pressing line and the horizontal rod is too close, which is easy to wear off the film. Therefore, it is better to use composite film EVA. In winter, the temperature is lower than -10 ℃, no matter which kind of greenhouse mulch is used, the insulation performance of straw curtain and quilt must be strengthened. Three layers of insulation measures, one layer of straw curtain, one layer of quilt and one layer of plastic, should be adopted.
2. Pay attention to the front and back of the shed film when applying the film. In general, the longevity non-drip film is printed on the outside. Please consult the purchaser in detail before buckling the film. The buckle film should be in sunny and windless weather; the film should be pulled gently to avoid scratches or punctures, and at the same time should be flattened, tightened, pressed firmly, and fixed.
3. To buy greenhouse films, choose large manufacturers with better quality, and don't try to be cheap, so as to avoid being deceived and lost.
4. The damaged film should be repaired in time. Polyvinyl chloride film PVC is glued with cycloacetone; vinyl acetate film EVA (including polyethylene film PE) is glued with XY-404 adhesive.
5. When using long-life non-drip film, a blade cloth can be used for cleaning and dust removal. A belt is set every 5 meters, and the outer surface of the greenhouse film is cleaned with natural wind to increase the light transmittance.
