4 kinds of microbial metabolites

Four kinds of microbial metabolites insecticides Details:
1 avermectin. Abamectin is a livestock and agricultural antibiotic. It is a neurotoxicity to insects. It has a wide-ranging killing effect on poultry, domestic and foreign parasites, crop pests, mites and parasitic nematodes. There are more than 80 kinds of control objects. The main dosage form is emulsifiable concentrate. In the 1990s, Beijing Agricultural University, Shanghai Pesticide Institute, and Huabei Pharmaceutical Factory successively researched and developed successful commercial preparations (Qiyusu, Insecticide, Aifuding, Aweiduqing, etc.). The product has excellent control effect against cotton bollworm, diamondback moth, mites, mites, etc., and the dosage is low. The control of cotton bollworm is only 1 to 3 grams per mu (active ingredient); the control of mites is 0.4~ per mu. 1.47 g (active ingredient). The manufacturers mainly include Zhejiang Haimen Chemical Plant, Huabei Pharmaceutical Group Ainuo Co., Ltd., and Jiangxia Star Antibiotics General Plant.
2 Liuyangmycin. Liuyangmycin is a cockroach antibiotic, which has more than 90% control effect on leaf mites that damage fruit trees, cotton, melons, beans, eggplant, tomato and pepper. The control effect on citrus rust tick and samovar is close to 100. %.
3 huaguangmycin. Huaguangmycin is low in toxicity, low in residue, free from pesticides and harmful to natural enemies. Datian has good effect on controlling leaf mites and citrus rust tick, and has certain control effects on plant diseases such as rice blast and cotton blight. It is a kind of agricultural antibiotic preparation for treating both diseases and insects.
4EB-82 oxytocin. It has a contact effect on a variety of aphids, and it also kills a variety of leafhoppers.

Compression Spring

Compression Spring (compression spring) is a helical spring which is subjected to pressure. It is usually made of a circular section of material, and is also rolled with rectangular and multi-ply steel. Springs are usually of equal pitch, cOMPRESSION SPRING SHAPE: cylindrical, conical, CONVEX and concave in the middle and a small number of non-circular, compression spring between the circle and the circle of a certain gap, when subjected to external load spring shrinkage deformation, storage deformation energy.

The compression spring (compression spring) is a spiral spring which is subjected to pressure. It is usually made of a circular cross-section of material, and is also made of rectangular and multi-ply steel, the shape of compression spring is cylindrical, conic, convex and Concave, and a few non-circular. There is a certain gap between the circle and the circle of compression spring, when subjected to external load, the spring shrinks and deforms, storage of deformation energy. Compression spring introduction to compression spring introduction to compression spring characteristics of helical spring subjected to compression to external pressure provides resistance to external pressure application of household appliances to power equipment spring pressure spring compression spring parameter compression spring specification compression spring selection compression spring specification parameter compression spring design compression spring fixed mode compression spring design outline compression spring (compression spring) is a helical spring subjected to compression, most of the materials used are circular in cross-section, and some are rolled in rectangular or multi-ply steel. The springs are generally of equal pitch. The shapes of compression springs are: cylindrical, conical, medium convex and medium concave, and a few non-circular, etc. , there is a certain gap between the circle and the circle of the compression spring. When the spring is subjected to external load, the spring shrinks and deforms, and the deformation energy is stored. Compression Springs provide resistance to external pressure. Compression springs are generally metal wires with equal pitch winding and a fixed wire diameter. Compression Springs use multiple open coils to provide resistance against external forces, such as the weight of the wheel or the weight of the body on the mattress. That is, they push back against external pressure. Compression Springs are generally metal wires with equal pitch winding and a fixed wire diameter. In addition, there are conic compression springs, or conic and linear combination of springs. Compression Springs can be used to resist pressure and/or store energy, depending on the application area. Round wire is the most commonly used compression spring, but there are square, rectangular and special shapes of wire manufacturing compression spring. Wire Springs with compression springs are used for everything from home appliances to power equipment, motors, etc. because they are the desired type of spring. By the load acting on them or their ends being compressed, the compression spring is compressed by the design of the wire in an attempt to return the spring to its original shape so that the load is pushed back. Main application: medical respiratory equipment, medical mobile equipment, hand tools, home care equipment, shock absorption, engine valve spring. Production Design 1. Look at the actual product requirements to choose the spring material. 2. According to product requirements, determine the internal and external diameter of the spring, the number of effective turns, and the value range of wire diameter. 3. The relevant parameters are substituted into the design parameter formula.
