The problem that graphite boat should pay attention to when maintenance is maintained

1. Prevention of strong corrosion of flame direct -injection engine graphite products side and bottom 砣;2. Use the entire process to turn the graphite boat once a week to improve the use period of graphite products;3. A proper interval should be kept in the middle of the graphite boat and the furnace wall, and graphite products should be put in the middle of the furnace;4. Pull out the coal ash and sticky conditions in the form of the form should be gently patted to prevent damaging graphite products;5. In the transportation conditions, it is necessary to hold it lightly, and it is strictly forbidden to fall;6. Strictly prevent the wet and cold, try to put it as much as possible or on the wooden shelf in the storage condition;7. The model specifications are the capacity of copper;8. Before using the dryer equipment or beside the furnace, it must be baked, and the temperature gradually rises to 500 ° C;9. The use of moderate combustion and additives will reduce the period of use.

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

How to Use Expanded Graphite

1. Protective purposesExpanded graphite can be used as a protective material to protect metals and other easily damaged objects, such as circuit boards and steel. Due to the fact that expanded graphite can expand up to 10 times, it can effectively block flames and prevent these objects from being burned by flames.2. Insulation purposeExpanded graphite can also be used as insulation material because it has good thermal resistance performance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing heat loss, and thus providing insulation.3. Filtering purposeExpanded graphite can also be used as a filter material because it has adsorption properties and can be used to adsorb toxic substances, such as pollutants in water treatment, effectively removing pollutants from water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement purposeExpanded graphite can also b

Optical and mechanical properties of graphene

Graphene has excellent optical properties, with an absorption rate of about 2.3% over a wide wavelength range, making it almost transparent. Within the thickness range of several layers of graphene, with each increase in thickness, the absorption rate increases by 2.3%. Large area graphene films also have excellent optical properties, and their optical properties change with the thickness of graphene. This is an unusual low energy electronic structure possessed by single-layer graphene. At room temperature, a voltage is applied to a double-gate double-layer graphene field-effect transistor, and the bandgap of graphene can be adjusted between 0 and 0.25 eV. When a magnetic field is applied, the optical response of graphene nanoribbons can be tuned to the terahertz range.When the intensity of the incident light exceeds a certain critical value, graphene's absorption reaches saturation. These characteristics allow graphene to be used as a passive mode-locked laser. This unique absorption
