Weeding film manufacturer * * *, wholesale of agricultural film in Hainan

The main products of Nanning Shenghexing Company, a manufacturer of weed control film and wholesale of agricultural film in Hainan, include industrial packaging film and agricultural film series. They provide extensive product support and services for chemical, aluminum, sugar, export packaging, tobacco and various modern agricultural companies, as well as farmers in Yunnan, Guizhou, Guangxi, Hunan and other provinces. The function of weeding film is as follows: 1. The silver surface has the ability to reflect ultraviolet rays, which can repel pests such as winged aphids and thrips, and reduce virus damage. 2. The silver surface has * * reflective function, which can increase the absorption of the fruit backlight. 3. The reflective effect of * * * can effectively reduce surface temperature. Under the same conditions, it can reduce surface temperature by about 2-4 ℃ compared to black plastic film and prevent burning of seedling roots. The higher thermal effect ensures that the surface temperature has good insulation effect and reduces temperature difference at night and in winter. Thermal effect (IR): refers to the ability to maintain the temperature of heat inside a film in a low-temperature environment at night or in winter. The unit of measurement for thermal effect is IR, and the transmission length of infrared radiation (IR) is the range of spectral penetration allowed by the film. The larger the IR, the smaller the heat. Generally, thermal effect is achieved by the inner layer (black layer), and the scattering rate (light scattering) is achieved by the outer layer (silver layer). The inner layer absorbs and blocks the infrared radiation escaping from the soil, and the scattering effect of the outer layer reflects it back into the soil to achieve insulation effect. 4. Promote photosynthesis in the root of crops and accelerate fruit coloring. 5. Prevent soil erosion, effectively control soil moisture, and reduce the occurrence of pests and diseases. 6. Anti aging additives make silver black mulch film longevity .....
