1. Prepare for use before use. Read and understand the instruction manual of the purchased equipment and prepare rubber (or plastic) gloves and masks (or gas masks).
2. In strict accordance with the provisions of the instructions for the preparation of liquid medicine. Emulsion pesticides should first be added with clear water in the medicine tank, then add the pesticide solution to the specified concentration, and be used after mixing and filtering; the WP pesticide should be first transferred into a paste, and then add fresh water, stir and filter .
3. use correctly. (1) Knapsack sprayer operation should first shake the rocker several times, so that the pressure in the air chamber reaches the working pressure and then open the switch, shake the rocker while spraying. If you shake the rocker feel heavy, you can not exert excessive force, so as not to damage the air chamber. (2) The knapsack sprayer should first check the oil system and ignition system according to the relevant operation method of the gasoline engine, and then start it to ensure the normal operation of the gasoline engine. When spraying, the machine should be in a spray state. Before adding the liquid, spray with clean water once to check whether there is any leakage at the joints of the machine. The liquid can't exceed the maximum water mark, and be sure to tighten the medicine cover after adding medicine. After starting the machine, first idle for 2~3 minutes, and then adjust the throttle switch so that the machine reaches the rated speed and opens the switch for spraying. After the switch is turned on, it is forbidden to stop spraying at one place to prevent phytotoxicity to crops. (3) When spraying, the operator's direction of travel should be perpendicular to the spraying direction to prevent the liquid agent from invading the operator. Nausea and dizziness should be stopped immediately during the operation. (4) During the operation, smoking and eating are strictly prohibited to prevent poisoning. After the operation is completed, all parts of the operator who come in contact with the liquid should be immediately rinsed with clean water and then washed with soapy water. (5) All wounded, breast-feeding or pregnant women, children and adolescents who are unhealed on the body should not be sprayed.
4. maintenance. After each use of the plant protection equipment is completed, the residual solution in the medicine box should be poured out, sprayed with a little clear water, and then washed with fresh water. After cleaning, put it in a ventilated and dry place. When parking for a long period of time, anti-rust butter should also be applied to moving parts and non-plastic joints.
Imported Premium Coupling Reagent
In plastic mixing, a plastic additive that improves the interfacial properties of a synthetic resin with an inorganic filler or reinforcer. Also known as surface modifier. It can reduce the viscosity of the synthetic resin melt and improve the dispersion of the filler to improve the processing performance in the process of plastic processing, so that the product can obtain good surface quality and mechanical, thermal and electrical properties.
Its dosage is generally 0.5 ~ 2% of the dosage of filler. Coupling agent is generally composed of two parts: one is the inorganic group, which can interact with the inorganic filler or enhance the material; The other part is the organophilic group, can interact with the synthetic resin.
