The Forming Process of Carbon Graphite Materials

There are various forming methods for carbon production, including four main methods: compression molding, extrusion molding, vibration molding, and isostatic pressing molding.Molding methodThis method uses a vertical press to make a mold according to the shape and size of the product. Then, a certain amount of mixed paste or powder is loaded into the mold on the press workbench. The press is started to apply pressure to the paste or powder, and maintained for a certain time to form it. Then, the pressed blank is ejected from the mold.The molding method can be divided into unidirectional pressing and bidirectional pressing, hot pressing and cold pressing according to different processes and equipment conditions. The molding method is suitable for pressing products with small size differences in three directions, uniform density, and high structural density and strength, but the products have anisotropy. Mainly used for producing electric carbon products and special graphite products.E

Introduction to the characteristics of scales graphite

Scales graphite is one of the types of graphite materials. It is a scale -shaped crystalline tissue structure. The performance of natural scales graphite products and good. It develops some rough processing, which can be processed into a variety of aimal specifications. What are the characteristics of scales graphite? Let ’s take a brief understanding.1. As a basic raw material, scales can be processed into ultra -fine graphite powder, expanded graphite, nano graphite powder, high pure graphite powder, etc.2. Scale graphite has good lubrication, high temperature resistance, conductivity, etc. Processing into a solid graphite lubricant is widely used for mechanical lubrication.3. The quality of scales graphite depends on the carbon content of graphite. The scales graphite is purified. It can be processed into high carbon, medium -carbon, and low -carbon scales graphite. Each graphite has different carbon content. Graphite, the better its industrial use.Scale graphite has strong heat sh

Causes of impure expandable graphite powder

1. The purity of high-purity graphite in the selection of production raw materials is immediately related to the ash content of the selected raw materials under the same production conditions. Civil expandable graphite products have the following pattern: those with high ash content in raw materials also have high ash content in their products. Therefore, the ash content of petroleum coke selected for the production of nuclear high-purity graphite is specified in the mouth. Below 15%, although the boron composition is required, analysis will be conducted, and the specific data information is all in 0. 5pp. Below. The total ash content of the product was divided into 5 parts in ppm, with boron content in the parts. The thermal neutron absorption cross section of the LPPM is 3. Eight times three. 94 millibars.2. The high temperature quenching and tempering treatment and other halogenation solutions have a fundamental impact on the removal of ash, as well as whether or not halogenation s

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
