Introduce the asphalt rubber pendant penetration processing process of graphite board

The general operating process of graphite immersion is after being loaded into the product, first vacuum packaging (gas in the gas in the pores in the pores of the product) and then put it in the impregnation agent to submerge the product, then pressure it to the liquid level, so that Essence It is used for different intentions, and the standards of impregnation agent processing process are not thorough. Below, I will introduce the asphalt rubber mud impregnation processing process of graphite board in detail.The whole process of processing the processing technology of asphalt rubber -soaking small graphite board, electrode connector and its graphite anode board:First of all, the semi-finished processing surface of the graphite board was burn, and then put it into the product box and put it in the temperature of about 4 hours in the temperature of about 240-Soot. After the heat, the product is quickly installed into the impregnation tank with the iron frame (the immersion can be heate

Basic overview of high-purity graphite?

High purity graphite is widely used in various industries, so its use is definitely very extensive. In fact, this high-purity graphite mainly means that the carbon content of graphite is more than 99.99%. It is also widely used in advanced refractory materials and coatings in metallurgical industry, stabilizers for military initiating explosive devices, pencil lead in light industry, carbon brushes in electrical industry, electrodes in battery industry, catalyst additives in fertilizer industry, etc. Of course, the scale crystals of the product are complete, thin and tough, with excellent physical and chemical properties. It has good thermal conductivity, temperature resistance, self-lubrication, conductivity, thermal shock resistance, corrosion resistance, and other properties. In addition, the high-purity graphite (also known as flake high thermal conductivity carbon powder) mentioned today has high strength. Of course, in addition to this, it also has advantages such as good therma

Why are the quality indicators of high-power and ultra-high-power graphite electrodes superior to ordinary power graphite electrodes

The current density of graphite electrodes used in high-power and ultra-high-power electric furnaces significantly increases, resulting in the following problems: (1) due to resistance heat and hot airflow, the temperature of the electrodes increases, resulting in an increase in the thermal expansion of the electrodes and joints, and an increase in the oxidation consumption of the electrodes; (2) The temperature difference between the center of the electrode and the outer circle of the electrode increases, and the thermal stress caused by the temperature difference also increases accordingly. The electrode is prone to cracking and surface peeling; (3) After the power of the electric furnace is increased, the electromagnetic force increases, causing severe vibration and increasing the probability of electrode breakage.Therefore, the physical and chemical properties of high-power and ultra-high-power graphite electrodes must be superior to ordinary power graphite electrodes, such as low

electronic effect

The load migration rate of graphene at room temperature is about 15000cm2/(v · s). This value exceeds 10 times the silicon material. More than twice. Under certain conditions such as low temperature, the load migration rate of graphene can even be as high as 250000cm2/(v · s). Unlike many materials, the electronic migration rate of graphene is less affected by temperature changes. At any temperature between 50 and 500K, the electronic migration rate of a single laye

Application of expanded graphite

What are the main expansion graphite equipment?

The difference between expansion graphite and expansion graphite is that expansion graphite is a process of expansion. It has a large volume, and the expansion graphite has no expansion. It has the characteristics of high temperature and rapid expansion. L.Swrite graphite natural graphiteA loose and porous worm -like substance obtained by insertion, water washing, drying, and high temperature puffed. It is one of the expansion graphite production equipment, mainly used for natural grinding processingProcessing link, H/L/MVertical grinding machineIt is a device specializing in graphite, which is very suitable for configuration as expanding graphite equipment.
