Performance characteristics of Shandong agricultural film
Shandong agricultural film has greater mechanical strength, better anti-aging properties, good elasticity, and can be restored after stretching. The mechanical strength of Shandong agricultural film is % of Shandong agricultural film, and its resilience Also worse. The light transmittance and surface aging performance are not as good as those of Shandong agricultural film. If sufficient anti-aging materials are not added when manufacturing the film, cracking, embrittlement and other phenomena will easily occur under strong sunlight. However, during use, the mechanical strength of Shandong agricultural film decreases with time at a smaller rate than that of Shandong agricultural film.
The air permeability and heat conduction speed of polyethylene plastic film are greater than those of Shandong agricultural film. Generally speaking, the speed of heat transfer is large, and the heat loss in the plastic film greenhouse is also large. Therefore, the thermal insulation performance of PVC plastic film is better than that of Shandong agricultural film, and the warming effect is also more significant. According to tests, the average temperature maintained by Shandong agricultural film is lower than that of Shandong agricultural film.
In agricultural film greenhouses, if water vapor increases, it will adhere to the film, forming a layer of fog and water and oil, causing the seedlings in the greenhouse to rot. It is different in Shandong agricultural film greenhouses. Because of its smooth surface, when water vapor in the greenhouse forms water droplets, it can flow into the soil along the film wall.
After Shandong agricultural film and Shandong agricultural film are damaged, they can be repaired by heat welding and adhesive. However, the effect of using adhesive to repair Shandong agricultural film is not as good as repairing Shandong agricultural film.
The speed of light passing through is different. Shandong agricultural film transmits light slower than Shandong agricultural film. However, Shandong agricultural film is prone to dust and is difficult to wash. As it is used for a long time, its light transmission performance is often worse than that of Shandong agricultural film.
Changle County Xiangguang Agricultural Film Products Co., Ltd. is an agricultural film manufacturer mainly engaged in Shandong agricultural film and agricultural film wholesale, providing reasonable agricultural film prices.
