How to extend the life of agricultural film
External damage at one time This is the most important factor affecting the service life of the film. For example, when the agricultural film is not tightened, when the strong wind comes, the agricultural film will swell and quickly beat the skeleton, causing damage to the agricultural film; the aged bamboo tendon will easily scratch the film after the break. Therefore, in the daily management, we must pay attention to these details.
Second, the temperature in the high temperature weather, the plastic film easy to aging rupture, especially the part of the plastic film and the skeleton contact, easy to form hot spots, the maximum temperature can reach 80 °C, this part of the agricultural film is particularly prone to aging damage. Farmers can use a white plastic band tied to the place where the skeleton contacts the membrane to prevent the agricultural film from being damaged by high temperatures.
Third, some pesticides will affect the life of the plastic film, especially the insecticides and fungicides containing sulfur or chlorine components will destroy the stability of the plastic film. The vegetable farmer must be careful when spraying the back of the leaves of the vegetables. Do not spray on the agricultural film.
Fourth, the use of different components of the film before and after, affect each other on the use of polyvinyl chloride film in the last quarter, if you want to change the EVA film in the next season, pay attention to the left and right sides of the wall of the PVC film withdrawal Net, so as not to accelerate aging after the two films are in contact. What needs special reminder is that some vegetable farmers use bamboo tires for bicycle tires. They do not know that such articles are also made of polychlorinated raw materials and are not good for the film. They should be replaced immediately.
