Application of Silicon Nitride Ceramic Bearing, Substrate, Cutter and Bar
Abstract: Silicon nitride ceramic is a kind of ceramic with high strength, high hardness and high heat conduction by sintering (reaction sintering, pressureless sintering, hot pressing sintering, etc.). Silicon nitride ceramics have excellent heat shock resistance, wear resistance and corrosion resistance, which can be used in bearing, substrate, cutter and shell.
Comparison of Six Methods for Making Silicon Nitride Powder
Abstract: The basic principle of the preparation of silicon nitride powder is to produce silicon nitride powder with high purity and specific crystal phase (α phase or β phase) by chemical reaction between nitrogen compounds and silicon compounds under suitable temperature and atmosphere.
Application of Aluminum Powder and Aluminum Alloy Powder
Abstract: Aluminum powder is a kind of silver white metal powder, which can be used to make paints, inks, pigments and fireworks. It can also be used as an additive of porous concrete. Aluminum powder can also be used for treatment and medical supplies. In addition, aluminum powder can also be used in the automobile and aircraft industry. Aluminum powder can be divided into spherical aluminum powder, irregular aluminum powder and aluminum alloy powder.
Application of Copper Powder and Copper Alloy Powder
Abstract: Copper powder is a kind of metal powder with red luster. Copper powder can be widely used in powder metallurgy, electric carbon products, electronic materials, metal coatings, chemical catalysts, filters, heat pipes and other mechanical and electrical parts and electronic aviation fields. Copper powder includes electrolytic copper powder, atomized copper powder and copper alloy powder. The specific classification and application are as follows:
SNC / EG / UHA / UHD Ultrafine Iron Powder
Abstract: Iron powder refers to iron particle powder with size less than 1mm. Its color is black. Iron powder is the main raw material of powder metallurgy. According to the particle size, iron powder can be divided into five grades: coarse powder, medium powder, fine powder, fine powder and ultra-fine powder. Iron powder with particle size of 150-500 μm is coarse powder, medium powder with particle size of 44-150 μm, fine powder with particle size of 10-44 μm, extremely fine powder with particle size of 0.5-10 μm, and ultra-fine powder with particle size of less than 0.5 μm.
How to Reduce the Likelyhood of Particulates Exposure When 3D Printing?
Abstract: From the PDF document (3D Printing with Filaments: Health and Safety Questions to Ask) published by NIOSH, we can learn that when 3D printing, work activities will bring certain exposure risks. Among them, there are 8 higher potential for exposures and 9 lower potential for exposures (We list all the potentials for exposures on the article: Could the Work Activity Cause Exposures When 3D Printing? What is the Likelihood of Exposure?). So, What measures should we take to reduce the the likelihood of exposure?
