High purity graphite, also known as flake like high thermal conductivity carbon powder, is actually a product that we are talking about today. It also has characteristics such as high strength, oxidation resistance, high temperature resistance, good thermal shock resistance, small resistance coefficient, and easy precision machining. What are the advantages of high-purity graphite for everyone?
High purity graphite is an ideal inorganic non-metallic material. High purity graphite has common advantages in the processing and manufacturing of structural casting molds, crucible pots for refining high purity metals, sintering molds, metal coating, and emission electron tubes. High purity graphite has corrosion resistance, with a uniform and fine matrix, which delays the corrosion degree of the product. In addition, it also has high thermal conductivity. The high content of fixed carbon ensures good thermal conductivity, shortens dissolution time, and significantly reduces energy consumption. Especially its quality stability, the manufacturing technology and quality assurance system of high-pressure forming method fully ensure quality stability. If graphite molds and other graphite processing products of various shapes and uses can be achieved in the metallurgical industry, graphite with precision and roughness can be processed. High purity graphite is specially designed based on the usage conditions of rapid heating and rapid cooling to ensure the reliability of product quality. High purity graphite can withstand high Thermal shock strength, so any process can be carried out safely. Of course, the addition of special materials significantly improves the quality of the crucible, exhibits excellent acid resistance index, and greatly extends the service life of the graphite crucible.
High purity graphite and its high content of fixed carbon ensure good thermal conductivity, shorten dissolution time, and significantly reduce energy consumption. Strict control of product material composition ensures that graphite crucibles do not contaminate metals during dissolution. In addition, the manufacturing process and quality assurance system of high-pressure forming method can fully ensure the stability of quality. Therefore, graphite has good chemical stability at room temperature and can resist corrosion by acids, alkalis, and organic solvents. Especially, the high-purity graphite mentioned today has good toughness, so it can be ground into very thin sheets. Exothermic welding sometimes requires various joint forms of exothermic welding molds. The plasticity of high-purity graphite can be used to make various models, specifications, and connection forms of exothermic welding molds. And when used at room temperature, high-purity graphite can withstand drastic temperature changes without damage. When the temperature suddenly changes, the volume of graphite changes very little and cracks do not appear. Of course, our company's products can still meet these needs, and we also welcome the establishment of long-term cooperative relationships with friends from all over the country. After all, it is well-known in this industry, with reasonable prices and guaranteed quality.
2023-04-20Graphene already exists in nature, but it is difficult to peel off a single layer structure. Graphene is stacked layer by layer to form graphite, with a thickness of 1 millimeter containing approximately 3 million layers of graphene. A pencil lightly scratches on paper, leaving traces that may be several or even just one layer of graphene.
1. Used as refractory material: Graphite and its products have properties of high temperature resistance and strength, and are mainly used in the metallurgical industry to manufacture graphite crucibles. In steelmaking, graphite is commonly used as a protective agent for steel ingots and as a lining for metallurgical furnaces.2. As a conductive material: used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, positive electrodes for mercury positive current transformers, graphite gaskets, telephone parts, coatings for television tubes, etc.3. As a wear-resistant lubricating material: Graphite is often used as a lubricant in the mechanical industry. Lubricating oil often cannot be used under high-speed, high-temperature, and high-pressure conditions, while graphite wear-resistant materials can work without lubricating oil at high sliding speeds at temperatures of 200-2000 ℃. Many devices that transport corrosive media are widely made of graphite m2023-10-10Introduction to Graphite Carbon Products
