Product Feature
Technical characteristics of graphite rod and blocks :
1, high temperature resistance: the melting point of graphite rod is 3850ºC±50ºC, and the boiling point is 4250ºC. It is 10s under the ultra-high temperature arc of 7000ºC, the graphite loss is the smallest, and the graphite loss is 0.8% by weight. It can be seen that the high temperature resistance of graphite is outstanding.
2, special thermal shock resistance: graphite rod has good thermal shock resistance, that is, when the temperature changes suddenly, the coefficient of thermal expansion is small, so it has good thermal stability, and will not crack when the temperature changes.
3, thermal conductivity and electrical conductivity: graphite rod has good thermal conductivity and electrical conductivity. Compared with ordinary materials, its thermal conductivity is quite high. It is 4 times higher than stainless steel, 2 times higher than carbon steel, and 100 times higher than ordinary non-metals.
4, lubricity: the lubrication performance of graphite rod is similar to molybdenum disulfide, and the friction coefficient is less than 0.1. Its lubrication performance varies with the size of the scale, the larger the scale, the smaller the friction coefficient, the better the lubricity.
5, chemical stability: graphite has good chemical stability at room temperature, can resist acid, alkali, organic solvent corrosion.

FAQ
Question 1: What are the main processes for producing extruded graphite rods and graphite blocks?
Answer 1: The main process for producing extruded graphite rods and graphite blocks consists of the following steps:
Raw material crushing: the original graphite material is broken to facilitate subsequent processing.
Grinding: Grinding the crushed graphite to make its particle size reach a certain range.
Screening: The ground graphite is screened to separate graphite particles of different particle sizes.
Kneading: The graphite particles after screening are added to the appropriate amount of binder, and then kneaded to form graphite mud.
Molding: The graphite mud is put into the mold and a certain pressure is applied to form the shape of the graphite rod or graphite block.
Roasting: The molded graphite rod or graphite block is roasted to enhance its physical properties.
Impregnation: The roasted graphite rod or graphite block is immersed in a special solution to increase its electrical and thermal conductivity.
Secondary roasting: the impregnated graphite rod or graphite block is roasted twice to make the special solution fully penetrate into the graphite structure.
Graphitization: The graphite rod or graphite block after secondary roasting is graphitized to obtain excellent electrical conductivity.
Mechanical processing: turning, drilling and other mechanical processing of graphite rods or graphite blocks to meet the needs of different fields.
Packaging: The processed graphite rod or graphite block is packaged to protect its surface from damage or contamination.
These steps are the main process for the production of extruded graphite rods and graphite blocks, and each step has an important impact on the quality and performance of the product.
Question 2: How long is the production cycle of extruded graphite blocks?
Answer 2: According to the specifications and requirements of the product, the production cycle of extruded graphite blocks is about 90 to 110 days. The exact time may vary depending on the production process, but typically the production cycle includes the following steps:
Question 3: What are the main applications of extruded graphite materials?
Answer 3: Extruded graphite materials have excellent electrical and thermal conductivity properties, so they are widely used in many fields.
Question 4: What is the price of extruded graphite blocks?
Answer 4: The price of extruded graphite blocks varies according to quality, use, size and other factors. In general, the price of high purity extruded graphite blocks is relatively high, mainly used in high-tech fields, such as semiconductor manufacturing. The price of ordinary extruded graphite blocks is relatively more affordable and suitable for general industrial fields.
