What kind of crushing of graphite blocks can be divided into?

The crushing of graphite blocks can be divided into three items, do you know? Let's take a look at it together!1. Pre -fragmentation (or crushing): This also refers to the crushing of block -shaped graphite block raw materials after entering the factory. Generally, it refers to crushing the block of the block of 200mm to 50 ~ 70mm. EssenceSecond, medium crushing: This also refers to the granularity of graphite block raw materials after forging to the particle size necessary for the seasoning. Generally, the block degree of up and down 50mm after the forging is crushed to 1 ~ 20mm.Third, fine grinding (or grinding): It is grinding part of the raw material of graphite blocks to 0.15mm or 0.075mm particle size below. Every time it goes through, the granularity of the raw materials has become smaller. The larger diameter of the large raw material before crushing is the ratio of the diameter of the larger block of the raw material after crushing, which is called a crushing ratio.

Let's take a look at the uses of battery specific graphite in industrial applications

The special graphite for batteries has good chemical stability, and the specially treated graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, so it is widely used to make heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pumps, and is widely used in petrochemical, hydrometallurgy, acid-base production, Synthetic fiber, paper making and other industrial sectors, Can save a large amount of metal materials.It is a material for casting, casting, pressing and high-temperature metallurgy. Because of its low coefficient of thermal expansion of graphite and its resistance to rapid cooling and heating, it can be used as a mold for glassware. After graphite is used, Ferrous can be used to obtain castings with accurate size, smooth surface and high yield, which can be used without machining or slightly processing, saving a lot of metal. In the powder metallurgy process of produc

Factors affecting the quality of silicon carbide grinding powder

Silicon carbide is widely used in industry and plays an important role. Silicon carbide can also be used as an abrasive, so the quality of silicon carbide particles is particularly important. We want to test its quality, so how to test its quality?Before proceeding to the analysis, the first thing we need to understand is that the abrasive is not only composed of particles of one shape, but only depends on the percentage of that shape. When analyzing the shape of abrasive grains, it can also be seen that the edges of the abrasive grain surface have characteristics such as smoothness, sharpness, rounded corners, straight lines, serrations, and cracks.Impurities are often mixed into the grinding powder. One is the components contained in the abrasive grains themselves, which are mainly formed during the smelting of raw materials, such as iron oxide, silicon dioxide, chromium oxide, and sodium oxide. Another kind of impurity is dissociated between particles, mainly iron filings and dust

How to solve the corrosion of the device in the scale graphite?

How to avoid the corrosion of the equipment on the equipment, thereby reducing equipment investment and maintenance costs, and improving production efficiency and profits is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but not high temperature, but scales graphite has both advantages. The following editors will introduce the problem of the device corrosion in detail how to solve the equipment of the scales:1. Excellent thermal conductivity. Scales graphite also has good thermal conductivity. It is the only non -metallic material with a thermal conductivity higher than the metal. The thermal conductivity coefficient is 2 times that of carbon steel and 7 times that of stainless steel. Therefore, it is suitable for heat transfer equipment.2. Excellent corrosion resistance. Various types of carbon and graphite have excellent corrosion resistance to all concentrations of hydrochloric acid, phosphate, and hydrofluoric acid, includin

Inspection of graphite crucibles before application

Graphite crucibles have excellent thermal conductivity and heat resistance during the pre application inspection work. During the entire high-temperature application process, the linear expansion coefficient is small, and they have certain strain resistance performance for rapid heating and quenching. Strong corrosion resistance to acid and alkaline solutions, with high-quality organic chemical reliability. It is widely used in metallurgical industry, forging, mechanical equipment, chemical plants and other industries for smelting alloy tool steel, rare metals, and aluminum alloys, and has good practical safety engineering effects.Generally speaking, in the inspection work of graphite crucibles before application, the following key aspects should be ensured:1. The first step is to check the graphite crucible for cracks before work. If there are no cracks, the graphite crucible needs to be heated to 600 ° C and dried sufficiently.2. There should be no water stored around the furnace or

The Artistic charm of graphite: the evolution from traditional craft to modern design

Graphite, this mineral with black as the main color, is not only widely used in industry and science and technology, but also shows a unique charm in the field of art.In traditional crafts, graphite is skillfully used in art forms such as painting and sculpture. The fine texture and easy coloring of graphite allow artists to create works with rich layers and full colors. At the same time, the hardness and wear resistance of graphite also make it an ideal material for engraving, which can be carved into fine patterns and textures.With the continuous development of modern design concepts, the application of graphite in the field of art is also constantly innovative. Designers take advantage of the unique color and texture of graphite and incorporate it into modern homes, decorations and artwork to create a distinctive visual effect. The simplicity and elegance of graphite inject new inspiration and vitality into modern design.In addition, graphite is also combined with many traditional

The research progress of battery material, new battery material

As the core component of new energy vehicles, the performance and stability directly affect the use of the vehicle. Therefore, the development of more secure and environmentally friendly battery materials has become an important research direction for the new energy vehicle industry. The battery is a wide range of energy sources, and now it has become one of the infrastructure of modern life. Compared with traditional batteries, modern batteries have better performance, longer life and smaller size. However, the improvement of this performance is inseparable from the progress of battery materials.1. Research on sodium ion battery materialThe sodium ion battery has become a new type of battery due to rich resources and low cost. The electrode material of the sodium ion battery is similar to the lithium battery, but the ion radius of the sodium ion battery is greater than lithium, which causes the transmission performance of the charge in the material to be greatly reduced. Therefore, t
