Our company has successfully developed ultrafine graphite powder

Qingdao Yuanshengrun Graphite New Materials Co., Ltd. Successfully Developed New Micropowder Graphite 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.

The impact of processing graphite on machines

Graphite is an important material and has wide applications in practical production and processing fields. The mechanical processing process of graphite is both complex and critical, and improper handling can have a certain impact on the machine.

The difference between colloidal graphite and flake graphite

Flake graphite refers to the raw ore of natural graphite, which is generally dried by nitric acid intercalation treatment and is called expanded graphite or worm graphite. Nano graphite powder is the subdivision of scale graphite after purification. If one dimension in the three-dimensional scale of an object reaches a certain order of magnitude, it is called nano material. Colloidal graphite refers to the dispersion system with particle diameter between 1nm and 100nm as colloid. Colloidal graphite belongs to nanomaterials.

Entering into Expandable and Expandable Graphite

Expandable graphite crystal is a typical carbon material with layered structure. Other heterogeneous particles such as atoms, molecules, ions and even atomic clusters are inserted into the layer of crystalline graphite by physical or chemical methods to generate a new layered compound, called Graphite intercalation compound, namely expandable graphite. Expandable graphite is different from expanded graphite, so expanded graphite should be selected as the sealing strip.

How worm graphite is formed

Worm graphite is an expandable graphite that, after expansion, forms a curly, worm like expansion graphite. The density of graphite is usually 2360kg/cubic meter, which can reach 800-1600kg/cubic meter after expansion.

High temperature resistant graphite paper

Graphite paper is a thin sheet-like product made from natural flake graphite through high-temperature hot pressing. Due to its excellent conductivity and thermal conductivity, this material is widely used in the electronic and electrical industry and military industry, such as mobile phone battery protection plates, lithium battery negative electrode materials, etc; In addition, due to its excellent high-temperature resistance, it is also commonly used in equipment under high temperature environments.
