The production process and use of expansion graphite

The expansion graphite is a loose and porous worm -like substance prepared by the procedure of graphite scales through the intervening, washing, drying, and high temperature. When the expansion graphite encounters high temperature, it can instantly swell 150 ~ 300 times in volume, which changes from sheet to worm -shaped, thereby loose structure, porous and bending, expanded surface area, improved surface can be enhanced. In this way, it increases its softness, return elasticity and plasticity.The expansion graphite is widely used, and the main development directions are as follows:1. Granules expand graphite: Small particles expand graphite mainly refer to 300 purposes that can expand graphite, and its expansion volume is 100ml/g. This product is mainly used for flame retardant coatings, and its demand is very large.2. Expansion of the swelling temperature at height: The starting expansion temperature is 290-300 ° C, and the expansion volume is ≥230ml/g. This type of expansion graphi

Chemical properties of graphite and carbon materials

Carbon materials are chemically inert in non oxidizing media. Under normal temperature and pressure, no chemical changes will occur. Except for long-term immersion in nitric acid, hydrofluoric acid, or in fluorine, bromine, and other strong oxidizing atmospheres, interlayer compounds will slowly form. It is not corroded by other acids, bases, and salts, and does not interact with any organic compounds. There is no significant oxidation phenomenon of graphite within 450 ℃ in the air. It only reacts with water vapor above 700 ℃ and with CO and CO2 above 900 ℃. The temperature at which graphite produces carbides with certain metal and oxide powders is mostly above 1000 ℃.The chemical reactions of carbon materials can be divided into the following three types:(1) Gasification reaction and high-temperature oxidation reaction;(2) Solid solid reactions with metals, ceramics, etc;(3) Formation reaction of interlayer compounds.

What are the quality characteristics of graphite model

Graphite has a lot of different high -quality characteristics. It is widely used in the metallurgical industry forging, the setting glass of mezzanine, and the industrialization of semiconductor materials. What are the high -quality characteristics of graphite mold? Let's take a look with graphite products manufacturers.1. High -quality heat transfer and conductivity. The conductivity of graphite molds is 100 times higher than that of ordinary mining companies. The heat transfer is beyond metal composite materials such as steel, iron, and lead. The heat transfer coefficient decreases with the temperature, and even at a very high temperature, the graphite becomes anrmal insulation.2. Very good thermal resistance. The solution point of graphite is 385050 ° C, and the melting point is 4250 ° C. Even if it is burned by high temperature, high voltage and electricity, the net damage is not large, and the line expansion coefficient is not large.3. Excellent thermal shock -resistant character
