What are the advantages of graphite molds?

The graphite mold materials used for diamond tool manufacturing are mainly graphite materials with ultra-fine particle structure, high purity, and high degree of graphitization. The average diameter of graphite mold materials is less than 15 microns, even less than 10 microns, and the average pore size is less than 2 microns. The graphite mold made from this carbon raw material has advantages such as low porosity, dense structure, high surface finish, and strong oxidation resistance, with an average service life of 30-40 times.Electronic sintered graphite molds and transistor supports can be manufactured using artificial graphite materials with minimal thermal deformation. At present, they are widely used and have become indispensable materials for the development of the semiconductor industry.The electronic sintered graphite mold of hot pressed sintered diamond tools has dual functions of heating element and mold support in the manufacturing process of diamond tools.

Precautions during the storage process of carbon material raw materials

(1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.(4) To prevent rain and snow from soaking in raw materials, it is neces

Graphite material type detailed introduction

Graphite material Type introduced in detail Key suitable for multi -type and small total aluminum compulsory. In other words, if you want to change the type of aluminum alloy, you must only exchange graphite . Graphite can be divided into five types based on the main use and its type. Below, everyone will introduce the graphite type in detail.1. Basic type: The ratio of the ratio of external specifications to high width is about 0.7 to 0.8 to 1. The volume is#8 ~#4500.2. Long type: longer than the basic type, the proportion of external specifications to high width is about 0.6 to 0.7 to 1. There are#15 ～#620 on the volume.3. Bowl type: The exterior specifications are relatively large, and the proportion of specifications to high and width is about 1: 1. The volume is#250 ～#5200. The larger one -time melting aluminum alloy material is about 1.5 tons.4. Bringing the shape of the mouth: close to the long -shaped soup slot. The volume is#50 ～#1800.5.

Excellent characteristics of graphite plates

Graphite plate is a good technical property, and its good properties are widely used in various industries. Due to the excellent chemical and physical properties of the product, it has gradually become a key raw material for making grinding tools. Graphite belongs to the raw material of graphite carbon. During the production process, alkaline resistant organic chemical compounds are added, and then subjected to high-pressure manufacturing and forming. After undergoing high-temperature heat treatment, production and processing are carried out, thereby reducing the porosity of graphite products, improving the relative density of products, and possessing good alkali resistance and wear resistance. Graphite plates have high-quality characteristics and are suitable for industries such as forging, metallurgy, and grinding tools. CNC lathe processing machines and equipment further enhance the overall production and manufacturing level, and consider the requirements for precision and surface

The technical requirements for refractory materials for scales graphite

Scales graphite has a strong heat shock resistance and good corrosion resistance. It is the main carbon raw material used in carbon resistance materials. It has an important effect on the corrosion resistance and high temperature intensity of carbon bricks such as magnesium carbon bricks. Essence In the actual production process, carbon -combined refractory materials have strict requirements for the purity, gray, particle size, shape and addition of scales graphite.A large number of studies have shown that the purity of graphite is directly related to the high temperature resistance strength of magnesium carbon bricks and the melting loss rate in use. The high temperature resistance of magnesium carbon bricks increases with the increase of graphite purity, which is the result of different micro -structures of magnesium carbon bricks. Magnetic carbon bricks made of lower -purity graphite have a larger thick pore and higher pore rate than high -pure graphite, which may be related to the

What is the advantage of expanding graphite?

Compared with other adsorption agents, expansion graphite has many advantages. If the activated carbon is used for water removal, it will sink after the absorption of oil. At the same time as absorbing oil, it also absorbs water, which brings difficulty in post -treatment; the expansion graphite has a large absorption of oil, floating on the water after oil absorption, easy to catch and recycled, easy to use processing processing Cleaning, combustion, heating extraction and other methods will not form secondary pollution.

Battery material, promote renewable energy development

In recent years, with the increasingly serious problems of environmental pollution and energy shortage, renewable energy as a clean, low -carbon, and sustainable development model has gradually been given important strategic significance. Among the applications of renewable energy, batteries as energy storage equipment are also an indispensable part of them. In order to further promote the development of renewable energy, we need to continuously explore new battery materials to improve the power density, cycle life and security of the battery.At present, researchers have proposed many new battery materials, such as lithium ion batteries, sodium ion batteries, zinc air batteries, etc. These battery materials can better meet the needs of energy storage and utilization compared to traditional lead -acid batteries, nickel -metal hydride batteries. Moreover, in the production process, the energy and materials they consume are also greatly reduced, which is more in line with the requirement
