Scales graphite is the main raw material for the casting industry.During the casting process, the scale graphite should be added to the casting, which helps the product to complete it faster and better, and improve the quality of the casting product. Therefore, the scale graphite for casting is the key raw material for the casting industry.2. How is graphite used to cast?Processing the cast -specific scales graphite into powder, and then add it to the outer surface of the casting and casting to make the casting easy to remove the mold. Casting dedicated scales graphite improves the surface quality of the casting, making the castings more abrasion and high temperature. This is the application of cast -specific scales graphite in casting and its abrasion resistance and high temperature resistance. There are many specifications for casting special sliced graphite powder. In different cast production areas, different thermal scale graphite should be used with different aims of casting.

It takes a long time at a lower temperature to observe the obvious creep, but at a higher temperature, the creep can be almost linear increased, that is, the peristalsis at a lower temperature increases only several times, and the temperature rises at a few times at a few times. The intervals when Baidu increased the index.2. The creep of scales graphite is also proportional to the exerted stress. In the same temperature and the same time, the greater the stress applied, the greater the creep.3. The creep of scales graphite is also related to the final heat treatment temperature of graphite. The higher the thermal treatment temperature, the smaller the scales of graphite.For the analysis of micro -quality impurities in scales graphite, the sample is usually pre -grayed or wet to digest carbon removal, dissolved ash with acid, and then determined the impurities in the solution. The measurement m
2023-07-25First, research on scales graphite antioxidant.The cold pressure of natural scales graphite non -adhesives into natural scale graphite samples, the effects of molding pressure and thermal insulation time on sample density, pore rate and folding strength. The relationship between the micro -structure and anti -folding strength of the natural scales graphite sample is qualitatively analyzed. The two systems of boric acid-urea and ethyl athyl-hydrochloric acid were selected to study and explore the antioxidant performance and mechanism of natural graphite powder and natural graphite electrode samples before and after antioxidant treatment.Second, the application of scales graphite antioxidants.The main component of graphite antioxidants -high temperature -resistant nano -ceramic particles, loosening in the water solvents, forming a light red and nearly transparent liquid source. In -pores that penetrate into graphite materials, form a layer of antioxidant protective film on the surface o
2023-07-24When 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. However, due to the large increase in scale graphite, the function of the coating will become fragile

It is an indispensable resource for the cultivation of the development of emerging industries and the transformation and upgrading of traditional industries. Graphite is mainly used as graphite materials in the nuclear industry, including the atomic reactor with neutron slow agents and reflexes, the production of hot column graphite for the production of isotopes, and the ball -shaped graphite and block graphite with high temperature and cold piles.2. Scales graphite and nuclear graphite are different branches of graphite materials.The scales graphite crystals are complete, thin -shaped, good toughness, stable physical and chemical performance, and have good temperature resistance, lubrication, conductivity, heat shock resistance, corrosion resistance, antioxidant, etc. Scales graphite is a very promisi
2023-07-24Scales 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
