Problems solved by technology

The current problem is that all kinds of fuming agent formulas that are conveniently prepared contain a large amount of anthracene, naphthalene and other toxic substances to the environment or human body
The fume pots made of various smoke fuming agents are ignited by the fuse, which requires a lot of manpower, low ignition efficiency and great harm
And it is greatly affected by temperature, humidity, altitude, that is, the oxygen content of the air. In the practice of large-scale smoking, there are cases where the ignition time is long or the smoking tank cannot be ignited.

Embodiment 1

[0017] When natural vibration is adopted, and the layout, position, quantity and size of the openings on the smoke pot are the same, when the fuse is used to ignite, the average ignition time is shown in Table 2.

[0018]

[0019] At room temperature, the average ignition time of each group has no significant change, and the misfire rate of the ignition index is 5-10%, but as the temperature drops, the misfire rate increases significantly, especially in winter when the ignition effect is lost at -20°C.

Embodiment 2

[0021] Under the same temperature conditions, the ignition conditions of each group of formulations were comparable. Consider that the formulations of each group differ only in substances with higher flash points. The ignition point of the fuming agent mainly depends on flammable substances such as sawdust with a lower ignition point. Therefore, the theoretical analysis is the same as the actual observation. Therefore, a formula is randomly selected for differential thermal test and thermogravimetric test. see attached results figure 1 , attached figure 2 .

[0022] The results of physical and chemical testing instrument analysis are consistent. It shows that the ignition point of each formulation is stable at a value, and the smoking agent is basically kept in the same temperature range during the smoking process. This provides a basis for the study of new electric igniters. In addition, the maximum smoke rate can be judged from the heat loss diagram of the smoker V'...

Embodiment 3

[0024] The invention also provides an electric igniter used for the long-distance and large-scale rapid smoking of the smoking pot. Because it involves flammable and explosive dangerous goods and pyrotechnics, the invention finally succeeded after going through hardships and a lot of experiments and explorations. Its preparation method is to coat a layer of acrylic glue on the ignition rod produced by Heilongjiang Jianhua Machinery Factory, and then connect it with an electric ignition head through a plastic pipe. The electric igniter is characterized by rain and water resistance, high ignition capacity and long time, short ignition time and stable and reliable effect. The actual test results are shown in Table 3.

Abstract

The invention relates to a smoke producing agent which is easily collected and suitable for massive applying, and a preparing and igniting method. The smoke producing agent comprises saw dust, diesel oil or fluorine, pulverized coal or TNT powder, potassium nitrate or ammonium nitrate; and 5% of sulphur is added while the smoke producing agent is treated as insecticidal smoke. According to the smoke producing agent, a high-energy electric igniting tool replaces a safety fuse for igniting, so that the distant operation is realized. According to the smoke producing agent and the igniting method, the main components are easily collected and nontoxic; the igniting is fast; the success rate is high; and the damage of toxic substances to human body is avoided.

Description

technical field [0001] The invention relates to a smoke-generating agent, a preparation method and an ignition method. Background technique [0002] Just as the smoking equipment is anti-visible light, its smoke screen has a direct effect on the scene matching guidance of precise strikes. Large-scale smoke screens are also widely used in crop pest control, wood fumigation, and crop frostbite prevention. The premise of large-scale smoking is local materials, low cost, and easy financing. The current problem is that all kinds of fuming agent formulations that are conveniently prepared contain a large amount of anthracene, naphthalene and other toxic substances to the environment or human body. The fuming cans made of various fuming agents are ignited by the fuse, which requires a lot of manpower, low ignition efficiency and great harm. And it is greatly affected by temperature, humidity, altitude, that is, the oxygen content of the air. In the practice of large-scale smokin...
