Environmental value of graphite: Transition from waste to resource

Graphite, a mineral widely used in the industrial field, has gradually been recognized for its environmental value. In the past, the waste generated during the mining and processing of graphite was often regarded as a useless burden, but with the deepening of the concept of environmental protection and the continuous development of technology, these wastes are gradually transformed into valuable resources.Through scientific recycling and treatment, the useful components in graphite waste can be effectively used to reduce the waste of resources. At the same time, reasonable treatment can also reduce the pollution of waste to the environment and realize the recycling of resources. This not only helps to alleviate the increasingly tight situation of graphite resources, but also meets the requirements of sustainable development.In addition, the application of graphite in the field of environmental protection is also expanding. For example, graphite can be used as a highly efficient adsorp

What are the characteristics of the thermal stability of the film -shaped graphite

Sheet -shaped graphite is a natural ore, with a thin piece or scale, and the aggregate is in the form of soil. It is a hidden crystal. Film graphite has many high -quality physical and chemical characteristics, including good thermal stability. Compared with other products, the thermal stability of film -like graphite has great advantages.Film graphite is one of the most high -temperature -resistant materials at present. Generally, the strength of the material is gradually decreased at high temperature. However, when heating to 2,000 degrees Celsius, the strength of the sheet -shaped graphite is twice the temperature at room temperature.Sheet -shaped graphite has excellent heat shock resistance. When the temperature suddenly changes, the thermal expansion coefficient is small, so it has good thermal stability. When the temperature changes rapidly, cracks will not occur.Sheet -shaped graphite is a material with excellent thermal shock. For graphite electrodes used in electric furnace s

The special function of the wiper with graphite powder

Wiper dedicated graphite powder is specially used to produce high -quality car wiper. The wiper is composed of wiper and wiper motors. The components of high -quality wiper and motor should be added with graphite powder. The wiper with graphite powder has excellent performance such as high temperature resistance, lubrication, and corrosion resistance.The following is a special function of the wiper with graphite powder:The car wiper is installed on the front window of the car, often exposed to high temperature and low temperature, and exposed to wind and sunlight. When the wiper works, it is basically in rainy days. When the wiper works, it should rub the glass of the car's front window, take the rainwater, etc., and clean the window. The wiper will be damaged if used for a long time. When producing a good quality scraper, graphite powder is usually added. The parts in the wiper motor are also made of graphite powder. Graphite used for wiper mainly plays a role in lubricating and redu

Can scales graphite be used as non -metallic fillers

When the scale graphite is used as a fire -resistant filler, it is an expansion of graphite powder. It is a graphite layer of inter -graphite compound obtained by natural graphite scales as raw materials. Under heating conditions, the volume of expansion graphite expands sharply (can reach 300 times) to suffocate flames, forming expansion together, which can be isolated flames, delaying or interrupting the spread of flames, not burning, flexible, high surface energy, and good coach layer. However, the volume and dose of swollen should be appropriately selected. Tests show that the best dosage is 150 μM particles, 30%expansion rates and 5%. The editor of the graphite manufacturer below introduces whether the scale graphite can be used as a non -metal filler and analyzes:Graphite can be used directly as a carbon conductive filler or a composite conductive filler for conductive coatings.
