Nuclear energy uses graphite material

Graphite is one of the deceleration materials and reflective materials used in nuclear reactors. Early reactors are graphite heaps. The nuclear reactor for structural materials use graphite using raw materials, process control, and finished product inspection than graphite electrodes. The nuclear reactor must have the following performance with graphite , High heat shock, good deceleration performance to fast neutron, stable size under radiation, and very small impurities. Boron, cadmium and other elements that are easy to absorb neutron should be strictly controlled.Nuclear graphite must have a high volume density M because the deceleration of graphite on fast neutron is relying on the collision effect of fast neutron to carbon atoms. One of the main indicators of nuclear graphite M is also directly related to the pore rate and penetration rate of graphite. In order to avoid the loss of nuclear fuel and heat carrier, M should reduce the pores and penetration rates to a certain level.

Skin graphite mineral procurement agent

Scales graphite is a crystalline crystal carbon. It has high electrical and thermal conductivity, high temperature resistance, stable chemical properties, low hardness and slippery. It is easy to adhere to the solid surface and can draw clear dark stripes on the paper. These excellent properties of the mineral selection process and minerals have made it widely used in industry. The following is the scales graphite minerals introduced by scales graphite manufacturers:Graphite ingredients, mining agents are mainly flotal, sometimes shaking sorting. This thin piece uses a static electricity selection method, but because the electrical selection needs to be fully dry and accurate, it is difficult to manage high -voltage power management in a humid environment, difficulty in processing fine particles, and cannot be promoted.In non -metal minerals, graphite is a relatively easy to float mineral. Therefore, scales graphite can only float well with foaming agents (such as pine oil oil, methax
