The main factors affecting the price of graphite molds are as follows

Graphite development direction

(1) Renewal of graphite selection and mining technology equipment

Artificial graphite characteristics

Crystal structureNatural graphite: Crystal development is relatively complete, the graphization of scales graphite is more than 98%, and the graphitization degree of natural micro -crystal graphite is usually below 93%.Artificial graphite: The degree of crystal development depends on raw materials and thermal treatment temperature. Generally speaking, the higher the thermal treatment temperature, the higher the graphite. The artificial graphite produced by industrial production is usually less than 90%.Organizational structureNatural scale graphite: It is a single crystal, which is simpler in the tissue structure. There are only shortcomings in crystalline learning (such as defects, wrong positions, errors, etc.). The grains of natural micro -crystal graphite are small, the clutter between the grains is arranged, and there is a hole after the removal of impurities, which shows the same sex in the macro.Artificial Graphite: It can be regarded as a variety of materials, including graphi

The application temperature category of graphite board

So, how much is the application temperature category of graphite board?The application temperature category of graphite board: -200-650 ℃ (in the air), -200-3000 ° C (in non-air oxidation substances).The structure of high -temperature graphite board is atomic crystals, and the middle price is connected in the middle of the oxygen atom, resulting in a porous material that stabilizes the positive hexagon. Because the covalent single -key is a ion key with a high key that can be very high, it must be highly mechanical energy to be damaged.The average graphite board is 1200 degrees. There is no problem in the following use, such as: precision processing parts processing, spark -loading wire cutting, industry creation, etc. The high -quality graphite board with high -quality characteristics can withstand high temperatures above 3000 degrees. Because the graphite board uses high -quality graphite carbon raw materials, it reasonably reduce the pore rate and increase the volume density, which

The application of graphite powder in the field of lubrication

The lubrication performance of graphite powder is very good. It can be applied in the field of industrial lubrication production. There are many lubricating applications for graphite powder. This is to use different specifications of graphite powder. Graphite powder can play a lubricating role. The smaller the diameter, the better the lubrication effect of graphite powder. The lubrication application of graphite powder can be used to produce various lubricating products and materials.The lubrication application of graphite powder can directly produce lubricating materials, or it can be used as composite materials. It can be processed with other materials. It can be made into graphite solid lubricants, molding agents, lubricating wear -resistant coatings, etc. Graphite powder with lubrication is made of natural scale graphite crushing processing. The scale crystalline structure of natural scales graphite has a good lubrication performance. To better, the scale graphite must be crushed

Introduce the knowledge and application of graphite chemistry

Graphite has a wide range of applications, and many products in our lives are inseparable from its role. We have also learned some basic knowledge of graphite before, and have a simple understanding of its application fields. We know very little about graphite. Only with more knowledge about the product can we apply it better in the future. The following is the graphite knowledge introduced by graphite manufacturers.Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance, graphite has many other uses besides abrasives. It is an excellent deoxidizer and can accelerate refining. The tapping speed is fast, the chemical composition is easy to control, and the quality of the steel is improved. Graphite powder is coated on the inner wall of the turbine impeller or cylinder through a special process, which can improve its wear resistance and prolong its service life. Furthermore, graphite is a semiconductor due to its high

Graphite products and other purposes

Defense industryIn the defense industry, the nozzle of solid fuel rockets is also used to make solid fuel rockets, the nasal cone of the missile, the parts of the universe navigation equipment, the insulation material and the anti -ray material.Anti -anti -rust and anti -rust materialGraphite can prevent boilers from scaling. Tests from relevant units show that adding a certain amount of graphite powder (about use per ton of water) to the water can prevent the surface of the boiler from scaling. In additionWith the continuous development of science and technology, people have also developed many new uses on graphite. Flexible graphite products. Flexible graphite, also known as expansion graphite, is a new graphite product developed in the age. The United States has studied successful flexible graphite sealing materials, solving the problem of atomic energy valve leakage, and then Germany, Japan, and France have also begun to develop and produce. In addition to the characteristics of n

Prevention and gray removal of graphite production and processing workshop

The anti -pollution -proof of graphite production and processing workshop is stable in the physical properties of ash graphite and no organic chemical corrosion. Therefore, the removal of the ash in the workshop does not need to consider anti -virus and corrosion resistance, mainly to reduce the concentration value of smoke and dust in the air and collect tiny smoke.First, to ensure the sealing of graphite production and processing workshop, and prevent environmental pollution from smoke and dust. Graphite production and processing workshop air has graphite smoke dust. Graphite smoke should be collected and purified according to the dust removal equipment before removing the workshop.In the secondary, graphite production and processing should be based on the concentration value of the smoke and dust caused by the system. Different CNC lathes, different concentrations of production and processing processes are different. For example, the concentration value of the smoke and dust concen
