Application of carbon black in optoelectronic countermeasure, fuming method and devices for realizing method

Abstract

The invention relates to a new application of carbon black in the optoelectronic countermeasure smoke screen, a fuming method and devices for realizing the method. The fuming method comprises the following step of preparing a smoke agent, canning and igniting, wherein the smoke agent is driven by a compressed gas to form a smoke screen, the prepared smoke agent is one-component carbon black, compressed air is filled during canning, a valve is used for ignition to replace a firing device, and the smoke-forming agent is driven by compressed air so that the agent is not heated, aerosol is formed and discharged in the air and an interference smoke screen is formed, and carbon black is perferably selected from ultrafine carbon black powder. The fuming devices contain a flow adjusting valve, a nozzle, a bottom ring, a guide tube, a guide tube plug seat, a powder-absorbing tube, a barrel, a machine head, a pressure gauge, a thimble, a carrying handle, a safety pin and a pressing handle. By adopting the fuming method and the fuming devices, visible light signals, laser signals and middle and far infrared signals can be effectively interfered; the formula does not contain a lot of dangerous chemicals and toxic substances and the smoke-forming components are greatly increased, thus energy can be saved and the environment can be protected; and the problem that the ignition times are different at different temperatures can be avoided and fuming can be stopped at any time according to needs.

Description

technical field [0001] The present invention relates to the use of carbon black, in particular to the use in the field of photoelectric anti-smoke. [0002] The invention relates to a carbon black fuming method, which comprises the steps of preparing a fuming agent, filling it in a can, and igniting it. The fuming agent is discharged into the atmosphere under the drive of gas to form a smoke screen. [0003] The present invention also relates to equipment for realizing the carbon black smoking method, including an ignition mechanism of a smoking tank, that is, a smoking mechanism, and a tank body. Background technique [0004] The smoke pots equipped at home and abroad generally use combustion-type smoke-generating agents and sublimation-type smoke-generating agents. The fuming process is as follows: prepare fuming agent, pack in a can, ignite, generate gas by burning the fumigant, and release a large amount of heat to sublimate the combustion product or fumigant into a gas...

AI Technical Summary

Problems solved by technology

It can be seen that they have the following deficiencies in use: 1. A large amount of toxic and harmful substances are generated during the formation of the smoke screen by the fumigant, some of which are still carcinogens

2. The smoke outlet reaches hundreds of degrees Celsius and is easily detected and monitored by the enemy's infrared and laser weapons. As the saying goes, it is easy to be retaliated by the enemy's precision strike weapons when used on the battlefield

3. Poor masking effect

Can only work on visible light and near-infrared

4. The unit price of effective smoke screen ingredients is more than 100 yuan or even hundreds of yuan per kilogram. The burden of procurement is heavy when used in large quantities, and it is difficult to store a large amount in peacetime

6. Once the smoke pot emits smoke, it is not possible to manually adjust the intensity of the smoke screen and stop the smoke at any time according to the wind force and direction

However, due to various reasons, there is a bias in the research work, that is, the study of tiny substances is ignored; as summarized in "Military Photoelectric System" written by Gao Zhiyun and published by Beijing Institute of Technology Press: "The difficulty of special smoke screens lies in the selection of materials, smoke screens Not only should it block the passage of the corresponding radiation, but it should also be suspended in the air for a long enough time. Unfortunately, such a material with large particles and light weight is difficult to find."
