Description
Technical field
The present invention relates to a kind of coating unit and method for coating, relate in particular to a kind of coating unit and coated side of nano metal powderMethod.
Background technology
At present, the main energy sources that industrial production and resident living are used comes from the fossil fuels such as coal, oil, natural gas. ItFeature be, forming process is extremely slow, fast consume under be faced with by exhausted situation. And fossil fuel combustionBurn the carbon dioxide producing and will increase the weight of tellurian greenhouse effects, its burning such as inner contained sulfide, nitride etc. will produceThe pollutant such as oxysulfide, nitrogen oxide, causes atmosphere pollution and forms acid rain, and harm natural environment has been not enough to adapt toThe fast development of modern industry.
Metal fuel is as a kind of New-type fuel of high heating value, and its energy density is far away higher than fossil combustions such as coal, oil, natural gasesMaterial. And, in the process of burning, can not produce the pernicious gas such as oxysulfide, nitrogen oxide. Meanwhile, on the earth, have richRich metallic mineral resources, and metal smelt technology maturation, can provide solid foundation for the application of metal fuel.
Owing to being subject to the restriction of metal dust production and processing level, traditional metal powder granulates diameter is larger, conventionally at 1 micronAbove, therefore its application is subject to larger restriction. Mainly as the filler of solid propellant rocket propellant, firebomb, photographThe luminous agent of bright bullet, the filler in explosive etc., range of application is relatively narrow. Along with novel production works such as discharge-induced explosion method, laser methodsThe appearance of skill, the particle diameter of metal dust has obtained further reduction. At present, diameter is less than the metal dust of 100 nanometersProduction technology very ripe, and can under controlled condition, to produce average grain diameter be 30 nanometers, 50 nanometers, 80The metal dust that nanometer etc. are different. Along with the reduction of metal powder granulates diameter, the specific area of metal dust increases exponentially,Its active significantly enhancing. This make nano metal powder can break away from before only as the state of metallic addition, become fuelMain body. Give full play to the characteristic of its high energy having, environmental protection. But the increase of nano metal powder activity has also brought oneFixed problem. If the nano metal powder of producing is directly exposed in air, will be by airborne dioxygen oxidation. NoOnly can make a part of nano metal powder lose activity, cause the decline of nano metal powder acting ability, and Nano metal powderThe heat that end produces in oxidizing process will make nano metal powder temperature raise, and likely causes chain reaction, cause fire orExplosion accident. For the nano metal powder that prevents from just having generated oxidized in the process contacting with air, need to be in nanometerWhen the harsh product of metal dust completes, just, at the coated one deck organic matter in its surface, prevent nano metal powder oxidation by air to reachObject.
Technical scheme of the present invention proposes under above-mentioned background, is intended to device by mentioning in technical scheme and correspondingMethod for coating, complete coated to nano metal powder.
