Description
Technical Field
The invention belongs to the technical field of pesticide preparations, and particularly relates to a special water-based environment-friendly auxiliary agent for a smoke cooling machine and application thereof.
Background
The pesticide hot fogging concentrate is prepared by dissolving a solid or liquid pesticide raw material in a solvent meeting certain viscosity and flash point conditions, and adding other auxiliary components to prepare a preparation with certain specification. In the using process, a certain amount of hot fogging agent is pressed into the firework tube by using a hot fogging machine, so that the hot fogging agent is mixed with high-speed and high-temperature hot air and is sprayed out of a conduit of the hot fogging machine to form micron-sized fog or smoke, and the preparation is called as the hot fogging agent. In hills and mountainous areas, the local crops mainly comprise high-stem crops such as corns, cassava, sugarcanes and the like, and also comprise fruit trees such as oranges, pear trees, apples and the like, economic forests and the like, and when the traditional pesticide application mode meets the problems of complex terrain, water shortage and the like, the pesticide application efficiency is generally low. The use of the hot fogging concentrate can obviously overcome the defects, and firstly, the hot fogging concentrate is hardly required to be mixed with water for application; secondly, the formed hot fog can be diffused naturally, and the spraying process can be carried out only by walking according to a specified route without considering the problems of the direction of a spray head, whether the route is repeated, whether the medicine is in place and the like; thirdly, the atomized fog drops of the hot fogging concentrate have good prevention effect and extremely strong penetrating power, greatly increase the contact probability with a target and more fully exert the prevention and treatment effect of the medicament.
The hot fogging agent commonly used in the market is heated and fogged by a hot fogging machine, which is called a smoke sprayer and a thermal fogger, and is also called a pulse fogger because the power of the hot fogging machine is pulse. The working principle of the hot fogging machine is as follows: the air and the gasoline form mixed gas in the carburetor, and under the condition of ignition, the mixed gas is explosively combusted to generate high-pressure high-temperature gas, so that the pesticide and the carrier thereof at the nozzle are instantly atomized and diffused to a target part under the drive of high-pressure airflow, and the purpose of protection and prevention is achieved. Most pesticide preparations cannot be directly applied to a hot fogging machine and need to be matched with a hot fogging machine auxiliary agent for use, and a solvent used by a traditional hot fogging machine auxiliary agent generally contains an organic solvent, for example, a pesticide auxiliary agent in patent document CN200510081634.5, which consists of vegetable oil, a cosolvent and a surfactant, wherein the cosolvent is an organic solvent; patent document CN201610845990.8 discloses a functional aid for a thermal spraying machine, and a preparation method and a use method thereof, wherein the functional aid for the thermal spraying machine comprises paraffin oil, a surfactant and a thermal spraying density regulator, wherein the paraffin oil is used as a solvent, and an organic solvent can cause certain harm to a human body and pollute the air environment.
The water-based environment-friendly auxiliary agent special for the smoke cooling machine is matched with a multi-nozzle adjustable electric smoke device for use, and the machine is similar to a hot fog machine commonly used in the market, but is different. The atomization principle of the machine is as follows: the equipment is powered by electricity, and a heating and atomizing device in the equipment is heated to a certain temperature under the control of an electronic circuit board; after the infusion pump is started, the liquid medicine is conveyed into the heating device from the medicine pot, is quickly vaporized by the heating device to form smoke, and is sprayed out from the smoke outlet by the pressure generated inside, the atomization temperature of the machine is between 90 ℃ and 310 ℃, the smoke can be quickly cooled to the temperature of the outside air 20cm to 30cm away from the outlet, the machine is safe to crops and operators, and scalding cannot occur.
The special water-based environment-friendly auxiliary agent for the smoke cooling machine is composed of a surfactant, a smoke agent, a defoaming agent and water, greatly reduces the use of organic solvents, is very environment-friendly, saves precious environmental resources, improves the prevention and treatment effect, and is a green auxiliary agent system.
