Graphite mold is mostly carbon, part of the air so that the graphite prone to oxidation at high temperatures, Typically graphite oxide at about 500 ℃ start, and with the graphite mold temperature increases the oxidation rate of oxidation of geometric growth intensified.Graphite mold is mainly graphite machining, and the periphery of each of the carbon atoms linked to three other carbon atoms covalently bonded to constitute a covalent molecule. Graphite mold has been used following areas: 1. artificial graphite die for hot pressing sintering of cemented carbide has the following characteristics: if pressed when the temperature increased to 1350-1450 degrees, the pressure can be reduced to the desired unit 67- 100 kg / sq cm (that is, cold pressure…
What is ultrathin graphite sheet?is it any different from the ordinary graphite sheet? The processing of ultrathin graphite sheet is similar to the ordinary ones: The expanded graphite powder with purity of >98%, put a certain amount of expanded graphite into the hot pressing die,meanwhile,vibrate the die to make the powder dispersed evenly,then place the die onto the powder compressing machine,set the temperature and pressure,and after that,start to heat pressing.keep this situation for a period of time,then get out the graphite sheet and heat it,and make it went through a double roller mill for several times to make finished product. The simple process below: What’s the main application of ultrathin graphite sheet(conductive graphite sheet)? With the development of the information…
Graphite plates with different dimensions are machinined from the raw material of the graphite blocks , we can make the machining according to the requirements and use situation of the customers , and it can be dicided into three kinds with the different kind of material . isostagic graphite plates , moulded graphite plates and vibracation graphite plates . Graphite blocks have good resistance to thermal shock, oxidation and corrosion, and have suitable resistivity and homogenous structure. They have been used extensively in industries like solar, foundry, chemicals, electronics, ferrous metals, high-temp, processing, ceramics and refractory. Graphite plates,It can be used to put as lining of metal tundish. The tundish function is to take the liquid steel slag and directing…
