China Drying News Fujian modified plastic technology development base with high efficiency and low toxicity insect repellent (triflumone, estrachlorphyrin, a combination of three Astragalus), PE wax dispersant, calcium silicate insulation agent, silane coupling Coupling agents, UV absorbers, and EVA resins were used as raw materials, and masterbatches with an anthelmintic function were prepared by coating dispersion, coupling treatment, smelting and blending, and extrusion granulation.
In addition, the masterbatch can be added to the LDPE resin in a proportion of 3% to 4%, and can be made into a film by a blow molding process, which can be used to cover vegetables, fruits and vegetables, and can be effectively used due to the slow release of the insect repellent in the film. Ground exterminates insects, leafhoppers, leaf roller insects, cabbage caterpillars, red spiders and other pests, reducing agricultural production costs, avoiding direct contact between pesticides and vegetables, significantly reducing the amount of pesticides used in crops and residues, and helping to increase crop yields. quality. This technology has been granted a patent.
