Description

Technical Field

[0001] The utility model relates to the technical field of tantalum-niobium powder cooling, in particular to a cooling device used in a tantalum-niobium powder grinding process. Background Art

[0002] Tantalum niobium powders are made of tantalum and niobium, two rare metals with high melting and boiling points. They look like steel, with a grayish-white luster, while the powder is dark gray. These metals have properties such as air absorption, corrosion resistance, superconductivity, unipolar conductivity, and high strength at high temperatures. Particle size adjustment: Grinding can make the particle size of tantalum niobium powder meet specific requirements. Different application fields have different requirements for the particle size of powders. Grinding is an important means to adjust the particle size distribution of powders and control the particle size. Improve uniformity: Through grinding, the particle size of tantalum niobium powder can be made more uniform, and the uniformity and consistency of powder can be improved. This is especially important for application fields that require precise control of material properties. Improve physical properties: Grinding can change the physical properties of tantalum niobium powder, such as density, fluidity, etc. By optimizing the physical properties of the powder, its processing performance and finished product quality in subsequent processes can be improved. Promote chemical reactions: In some chemical reactions, the surface area and particle size distribution of the powder have a significant impact on the reaction rate and reaction effect. Grinding can increase the specific surface area of ​​tantalum niobium powder, promote its reaction with other substances, improve reaction efficiency, and improve material properties: through grinding, large particles and impurities in the powder can be eliminated, and the purity of tantalum niobium powder can be improved. This helps to improve the performance of the material, such as conductivity, corrosion resistance, high temperature stability, etc.

[0003] Chinese Patent Authorization Announcement No.: 200480022801.2, provides tantalum powder and its manufacturing method, the scheme is generally to provide tantalum powder with thin flakes, nodular and / or polygonal wet grinding, another feature is to provide tantalum powder and other valve metals, which preferably have high surface area and other physical properties, which allows tantalum powder to form capacitors with relatively high capacitance, another feature is to provide tantalum powder and other valve metals, when forming capacitors, it has relatively low DC leakage, but tantalum niobium powder needs to be cooled during grinding, high melting point and high thermal conductivity: tantalum and niobium are both high melting point metals, they will generate a lot of heat during grinding due to friction and deformation. If not cooled in time, this heat will accumulate rapidly, resulting in temperature rise during grinding, and may even reach the melting point of the material, causing the powder to melt or agglomerate, affecting the grinding effect and product quality, and preventing oxidation: tantalum and niobium are both metals that are easily oxidized. At high temperatures, their reaction rate with oxygen in the air will accelerate, resulting in oxidation of the powder surface, reducing the purity and performance of the powder. Cooling helps to reduce the temperature of the grinding area, thereby slowing down the oxidation process and protecting the grinding tools: high temperature will cause increased wear of the grinding tools and shorten their service life. Cooling can reduce the temperature of the grinding tools and reduce thermal stress, thereby protecting the tools, improving grinding efficiency and maintaining the dispersion of the powder: high temperature may cause agglomeration or agglomeration between powder particles, affecting the dispersion and uniformity of the powder. Cooling helps to keep the powder in a loose state, which is conducive to subsequent processing and use, and improves operational safety: sparks or spatters may be generated during high-temperature grinding, increasing operational risks. Cooling can reduce these risks and improve operational safety.
