Graphite Powder Manufacturing Methods
Graphite powder is an important raw material for the production of chemicals, which is widely used in metallurgy, casting, machinery, chemical industry and other fields. With the continuous progress of science and technology, the manufacturing method of graphite powder is also continuously improved and optimized. This article will introduce a common graphite powder manufacturing method.
I. Raw material preparation
The main raw material for manufacturing graphite powder is natural graphite or artificial graphite. Before manufacturing, it is necessary to carry out quality inspection of raw materials to ensure that their purity and particle size meet the requirements. At the same time, the production equipment needs to be cleaned and sterilized to ensure the hygienic quality of the product.
II, crushing
will be ready to put the raw materials into the pulverizer for crushing, generally using mechanical crushing. In the crushing process, you need to adjust the parameters of the pulverizer according to the requirements of the product to obtain the required particle size and particle size distribution. After crushing is completed, the crushed material needs to be sifted to remove too large or too small particles.
Three, grading
After sieving, the material needs to be graded. The purpose of grading is to separate materials of different particle sizes to obtain the desired size of graphite powder. Generally use the method of airflow classification, the use of different particle size materials in the airflow with different settling speeds, the material will be graded. After the grading is completed, graphite powder of different particle size needs to be packed and labeled separately.
Four, surface treatment
In order to improve the surface activity and dispersibility of graphite powder, graphite powder needs to be surface treated. Generally the method of chemical treatment is adopted, using acid, alkali and other chemical reagents to modify the surface of graphite powder. After the treatment is completed, graphite powder needs to be cleaned and dried to remove the chemical reagents and moisture on the surface.
V. Quality inspection
After the manufacturing is completed, graphite powder needs to be inspected for quality, including particle size, purity, surface activity and other aspects of the test. After passing the inspection, it can be sold at the factory.
The above is a common graphite powder manufacturing method, the specific process and operating parameters will vary according to different equipment and product requirements. In the manufacturing process, attention needs to be paid to the maintenance and repair of equipment to ensure the stability of the production process and product quality. At the same time, it is also necessary to strengthen the control of the production environment to ensure product hygiene and quality and safety.
In short, the manufacturing method of graphite powder is a complex process that requires a variety of technical and operational experience. Only by mastering the correct manufacturing methods and operating techniques can we produce high quality graphite powder and provide reliable raw material guarantee for chemical production.
