The graphite which are in different properties should use different processing methods, we will give you a brief introduction: Purification processing of the graphite products : the requirements of graphite products in modern industrial focus on the development of two aspects: the first, the requirements of large crystal scales to achieve high purity, and the second is required to achieve ultra fine graphite particles (such as less than 1 m or 0.5 m). Our company has established the production lines of graphite purification and fine powder processing , the purification method is mainly chemical purification. The most mature technology of graphite chemical purification is melting the caustic alkali and graphite at 700 DEG C, and then washing them to neutral,…
The rigid composite graphite felt is based on PAN based carbon felt as the base material after above 2200 degrees high temperature graphitization treatment, and then treated through carbonization and graphitization by special adhesive composite. The rigid composite graphite felt has certain rigidity, self support, the proportion of small, low thermal conductivity, no fiber shedding and the using temperature can reach 3200 DEG C. It’s suitable for various types of furnace types such as high pressure gas quenching furnace, pressure sintering furnace, polycrystalline casting furnace, single crystal growth furnace (sapphire), etc. the utility model can provide various shapes such as flat plate, disc and cylinder, etc. It has the advantages of long service life, it’s convenient to install and dismantle.…
Graphite crucible is widely used in the experiment and the melting of metals and graphite crucible materials with special graphite materials of high purity and high strength and high density; after high precision CNC machining equipment, can produce a graphite crucible, graphite crucible, graphite casting, oil groove tube, pull piece, pull rod mold special graphite graphite products. The material selected for the precious metal smelting crucible, graphite crucible can make products than ordinary products and durable degree more than 2 times, longer service life, more can withstand high temperatures above 2000 degrees Celsius! The graphite crucible is characterized by good thermal stability of 1 graphite crucible, graphite crucible for rapid heating and cooling conditions of use, especially the formulation 2.…
