Types, properties, and uses of mechanical carbon graphite products

Mechanical carbon graphite products are carbon graphite materials used as structural components in various machinery, including various graphite bearings, graphite sealing rings, graphite piston rings, graphite sliding plates, and graphite brake friction plates.According to different production processes, mechanical carbon graphite products are mainly divided into 7 categories: (1) carbon graphite; (2) Electrochemical graphite; (3) Resin impregnated carbon and electrochemical graphite; (4) Carbon and electrical graphite impregnated with metal; (5) Carbon graphite material with resin as binder; (6) Metal - graphite material; (7) Flexible graphite material.Mechanical carbon graphite products can work in corrosive media within the temperature range of -200~2000 ℃ and operate normally without lubricating oil at high motion rates. They have self-lubrication, good wear reduction performance, high thermal conductivity and heat shock resistance, low linear expansion coefficient, and good mech

Environmental value of graphite: Transition from waste to resource

Graphite, a mineral widely used in the industrial field, has gradually been recognized for its environmental value. In the past, the waste generated during the mining and processing of graphite was often regarded as a useless burden, but with the deepening of the concept of environmental protection and the continuous development of technology, these wastes are gradually transformed into valuable resources.Through scientific recycling and treatment, the useful components in graphite waste can be effectively used to reduce the waste of resources. At the same time, reasonable treatment can also reduce the pollution of waste to the environment and realize the recycling of resources. This not only helps to alleviate the increasingly tight situation of graphite resources, but also meets the requirements of sustainable development.In addition, the application of graphite in the field of environmental protection is also expanding. For example, graphite can be used as a highly efficient adsorp

Popular Science Knowledge of Graphite Crucibles

Crucibles can be divided into three categories: graphite crucibles, clay crucibles, and metal material crucibles. In graphite crucibles, there are three types: regular graphite crucibles, irregular graphite crucibles, and high-purity graphite crucibles. Various types of graphite crucibles differ in performance, main uses, and application standards, resulting in differences in commonly used raw materials, production methods, production processes, and product specifications and models.The main raw material of graphite crucible is pure natural graphite in crystalline form. Therefore, it maintains the various physical and chemical characteristics of pure natural ink.Namely, it has excellent thermal conductivity and heat resistance, and has a small coefficient of linear expansion throughout the high-temperature application process. It has certain strain resistance performance for rapid heating and quenching. Strong corrosion resistance to acid and alkaline solutions, with high-quality orga

Expansion graphite, a new multifunctional insulation material

Expansion graphite is a kind of graphite that can expand and shrink in high temperature environments. This material has very special physical and chemical properties. Graphite is a kind of carbon, and its structure is connected by hexagonal carbon atoms. Generally, graphite can be completely melted, but at high temperature, due to the enhancement of the interaction between carbon atoms, graphite can form more stable stability The structure of the expansion is achieved.1. The development of expansion graphiteThe development of expansion graphite dates back to the 1960s. At that time, scientists discovered that graphite can be deformed regularly within a certain temperature range, and the translucent graphite can remain stable. Subsequently, scientists also found that under certain conditions, graphite at high temperature can be used to create a variety of structures, and these structures can be used to support greater weight and develop the technology of expanding graphite.Second, the

What is graphite

Graphite is a kind of homogenous alien body for carbon. It is gray -black, opaque solid, stable chemical properties, corrosion resistance, and it is not easy to react with drugs such as acid and alkali. Natural graphite comes from graphite ore. It can also be used as a raw material for oil coke, asphalt coke, etc., and made a series of processes to make a human -made graphite. Graphite is burned in oxygen to generate carbon dioxide, which can be oxidized by strong oxidant such as concentric acid and potassium permanganate. It can be used as an anti -wear agent and lubricant. High -purity graphite is used as a neutron decelerator in the atomic reactor. It can also be used to manufacture crickets, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, and arc

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Graphite board antioxidant solution increases the period of use

After the formation of graphite board, it must be solved by antioxidantization. Generally, antioxidants are used, which is a thick liquid state. The ingredients are heat -resistant nano -ceramic particles. In the natural environment of air oxidation within 1300 ° C in the application temperature of the graphite board, its antioxidant actual effect is very good. After a variety of specifications of graphite boards with pre -immersed in the antioxidant protective film, its liquid can penetrate into the pores of the graphite board. The sexual protective membrane is exactly the reasonable blocking gas of this layer of protective membrane immediately touched with the graphite plate to produce oxidation reactions. Then it can reasonably resist the air oxidation of the graphite board and increase the use period of graphite board.The period of use of graphite boards has continued to increase, and the service life of traditional raw materials has already increased significantly.
