Taicang Jingang Plant Protectiong Machinery & Technology Co., Ltd. was founded in Jan. 2007. We specialized in research and production of new types of plant protection apparatus and machinery, such as electrostatic sprayer, etc. We are a professional manufacturer, involved in R&D, production, and sell of new plant protection apparatus and machinery. Based on modern science and patent innovation, take serving rural areas and benefit farmers for our tenet, powered by meeting current rural and farmers&＃039; actual demands, take upgrade plant protection apparatus and machinery of China as our mission, we try our effort to explore, innovate, practice, and we had achieved many good results. Around R&D subject of electrostatic sprayer, we had obtained 3 invention patent certificates and 7 utility model patent certificates issued by the State Intellectual Property Bureau. The testing results of an electrostatic sprayer we developed, tested on Dec.26, 2007 by the National Plant Protection Machinery Quality Supervision and Inspection Center, show that the cover density of droplets is around 300 per square centimeter on face and about 180 droplets per square centimeter at backside (static adsorption effect proportion face to backside reached 100:60), median droplets diameter is 72 microns. The two important parameters mean that the electrostatic sprayers we developed and produced have the advantages of saving water, saving pesticides, saving labor, green, environmental protection, and highefficiency. It will bring huge economic and social benefits to China agriculture and rural modernization agricultural and the countryside modernization construction and industries of plant diseases and pests control, health and epidemic prevention, and disinfection and disinsection, etc. Electrostatic sprayers with brand registered FOG STAR we now producing are in 3 specifications, including 8 liters and 16 liters high-speed centrifugal spray, and 16 liters high water pressure mist spray.
