Raw materials

imported graphite, isostatic graphite, high-strength high-purity graphite, fine structure graphite, graphite electrode

Due to its special structure, graphite has the following special properties

1) High temperature resistance:

The melting point of graphite is 3850 ± 50 . Boiling point is 4250 ℃. Even if it is burned by ultra high temperature arc, its weight loss is very small, and its thermal expansion coefficient is also very small. The strength of graphite increases with temperature. At 2000 ℃, the strength of graphite is doubled.

2) Conductivity and thermal conductivity:

Conductivity of graphite is 100 times higher than that of common nonmetallic ores. Its thermal conductivity exceeds that of steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature. Even at extremely high temperatures, graphite becomes an insulator. Graphite can conduct electricity because each carbon atom in graphite forms only three covalent bonds with other carbon atoms. Each carbon atom still retains one free electron to transfer charge.

3) Lubricity:

The lubricating performance of graphite depends on the size of graphite flakes. The larger the scale is, the smaller the friction coefficient is, and the better the lubrication performance is.

4) Chemical stability:

At room temperature, graphite has good chemical stability and is resistant to acid, alkali and organic solvent corrosion.

5) Plasticity:

Graphite has good toughness, which can be rolled into very thin sheets.

6) Thermal shock resistance:

When used at room temperature, graphite can withstand sharp changes in temperature without damage. When the temperature changes suddenly, the volume of graphite changes little and no cracks will occur.

Graphite boat

Graphite boat is the most representative category of graphite production and processing. With the continuous completion of its efficacy, the comprehensive use area has been greatly improved.

The high-quality graphite boat is specifically built through high-precision machining equipment and good process flow, thus meeting the diversified requirements of modern production for the graphite boat. Especially in terms of specific size requirements, standardized production processes have been developed, which provides the most powerful guarantee for meeting specific size requirements. The improvement of production technology also largely meets the requirements of modern production for good appearance.

The qualified graphite boat depends on continuous improvement of its material selection requirements and standards. By introducing high-purity graphite materials, the graphite products have low impurity content and excellent comprehensive quality, so as to better meet the requirements of non deformation use under long-term high temperature. It is better to meet the customer's requirements for the use of graphite boat.

Graphite boat ceramic assembly adopts the highest standard ceramics on the market. The imported materials can further improve the comprehensive anti-corrosion performance through the play of auxiliary effects. This makes it not easy to burst, and better delay the comprehensive service life. The service life of the ink boat and the full play of its use effect are closely related to the daily maintenance. The graphite boat itself is special, so the specific maintenance work should be completed as much as possible according to the requirements of the manufacturer of the graphite boat.

 

1. Storage of graphite boat

The graphite boat with good quality should be stored in a dry and clean environment. The pore structure of high-quality graphite itself makes it have a certain degree of adsorption. The wet or polluted environment will make the cleaned and baked graphite boat easy to be polluted or damped again. Only by ensuring the conformity of the storage environment can we provide the most powerful support for the subsequent guarantee of the use efficiency of the graphite boat.

2. Handle with care

The ceramic and graphite parts of the best-selling graphite boat components all belong to fragile materials. In the process of handling or use, collision shall be avoided as far as possible;. If the components are found to be broken, cracked, loose, etc., they should be replaced and locked again in time.

3. To achieve matching maintenance of auxiliary parts

During the maintenance of the graphite boat, it is suggested that the components, boat pieces and process cards should be provided by the supplier of the graphite boat. This can avoid the damage caused during the replacement process due to the failure of the component accuracy to match the original boat.

4. To do a good numbering management as far as possible

In applications, the graphite boat shall be numbered and managed as much as possible, as well as design and make regular cleaning, drying, maintenance and inspection. It will ensure good management on graphite boat and stability on its application. The integrally cleaned graphite boat shall replace the ceramic components regularly. It plays an important role in the orderly maintenance of the graphite boat.

In order to better ensure the improvement of the use efficiency of the graphite boat, better reduce the maintenance cost, timely carry out maintenance in daily use, and carry out systematic planning and system according to relevant processes.

Battery graphite tiles

Fuel cell system is a set of power generation system, which conducts electrochemical reaction through hydrogen and oxygen. It discharges water.

It has three characteristics: zero emission, high energy density, high volume specific power density and high mass specific power density; It has long service life. In the past nearly 20 years, fuel cells have been in the stage of technology development and exploration. In fact, no matter in North America, Europe or Japan and South Korea, they have never given up the research and development of fuel cells. In China, there are more than 9 billion M&A investments. Graphite carbon plate is made of high-quality graphite carbon material, and organic compound with strong acid resistance is added. It is refined by high pressure forming, vacuum impregnation and high temperature heat treatment process. They have excellent acid and temperature resistance. Graphite carbon plate is an ideal lining material for phosphoric acid reaction tank, phosphoric acid storage tank and other equipment in chemical industry.

Graphite plates (stacks) are commonly used in fuel cells. A fuel cell consists of about 100 graphite plates. The price of each graphite plate depends on the size. At present, the price of each piece in the market ranges from tens to hundreds of yuan. At present, there are few domestic enterprises producing such graphite plates. With the acceleration of fuel cell industrial production, it is expected that the market demand for graphite plates for fuel cells will increase significantly.

Graphite powder products

Graphite powder is an important industrial raw material. Graphite powder is used in lubrication, sealing, conductivity, high temperature resistance, refractory, chemical production and other industrial fields. The most widely used graphite powder in industry should be in the field of high temperature resistance. In the production of casting industry, castings are carried out in the high temperature environment during the casting process, in order to make the castings not deform and fracture at high temperature. Cast graphite powder can withstand high forging temperature. The casting graphite powder is added to make the surface of the casting smooth and sand free, which can ensure the quality of the casting. Thus, it has good high temperature resistance properties.

The high temperature resistance of graphite powder can be used in the production of continuous casting graphite powder, graphite powder casting detergent, graphite powder crucible, graphite powder refractory brick, lubricating oil and grease.

By adding graphite powder, the crucible made of graphite powder and the refractory brick made of graphite powder have the property of high temperature resistance. The disadvantage of commonly used lubricating oil and grease is that they cannot withstand high temperature. They do not lubricate at high temperatures. Adding graphite powder in the production process of lubricating oil and grease can not only increase the lubricating performance of lubricating oil and grease, but also improve the high temperature resistance of lubricating oil and grease. Different properties of graphite powder have different applications in industry. According to different uses of graphite powder, the specification, quality and price of graphite powder are different.
