The application of scales in the casting industry

1. 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.

Is it true that diamonds "fly" out of graphite powder

Do you know what a diamond is? Its chemical composition is carbon (C), and natural diamonds can only be called "diamonds" after being polished by diamonds. Natural diamonds are very rare, with only 2 diamonds weighing over 1000 carats (1 gram=5 carats) in the world and only a few diamonds weighing over 400 carats. The largest diamond discovered in China to date weighs 158.786 carats, which is known as the "Changlin Diamond". Rare things are precious, and precisely because natural diamonds that can be used as "diamonds" are rare, people want to replace them with "artificial" diamond, which naturally reminds them of the "twin" brother of diamonds - graphite.The chemical composition of diamond and graphite is carbon (C), which scientists refer to as "homomorphic variants" or "allotropes". From this term, it can be inferred that they share the same "quality", but their "form" or "nature" are different and vastly different. Diamond is currently the hardest substance, while graphite is one

The four major development trends in the field of graphite mold

Under the harm of China's economic development and the prevalence of Internet e -commerce prevailing, the shuffle in the graphite mold industry will increase, and the company has encountered a lot of challenges and opportunities. Therefore, the company only has the future development trend of the field, and moderate transformation and development and adjustment can really take the initiative to take the initiative and obtain dominance.1. High -end and precise positioning will be more noticedThe different advantages of graphite molds decide that it has a wide industry prospect. Under the prerequisites for giving full play to their own advantages and improving the entire process, Commodities have gradually entered the customer's field of vision. Customers' requirements and expectations for high -end products are getting higher and higher. The tentacles of high -end products have long been widening to many customers. Market demand will slowly gather to high -end, and the sales and growth

What are the main uses of graphite carbon boards

What are the main uses of graphite carbon plates? The graphite carbon plates are high -quality graphite carbon raw materials, and the organic chemical complexes with strong alkali resistance are used. It is made of compression, vacuum pump pre -immersing, and high -temperature thermal treatment methods. It has extraordinary acid resistance. It is an idealized lining material for machinery and equipment such as ammonium sulfate reflection and ammonium sulfate storage tanks such as ammonium sulfate in the chemical manufacturing industry.Graphite products use high -quality graphite charcoal materials, coupled with organic chemical complexes with strong alkali resistance, reasonably reduce the pore rate of the product and improve the volume density of the product. Therefore, graphite products have excellent corrosion resistance and Strong abrasion resistance.Detailed description of graphite production and processing on graphite board:The main purpose:1. Failure-resistant material and lubr

Let's talk about the basic characteristics of graphite

I. Special seismic resistance: Graphite's expansion gear is different, so the macro expansion coefficient is not large. In the case of sudden changes in temperature, graphite volume has not changed much; coupled with its good thermal conductivity, graphite resistance is excellent.Second, lubrication: The graphite layer is Van Der Waal Forces, which combines weak combination to make it lubricating. The lubrication of graphite depends on the size of the graphite scales. The larger the scales, the smaller the friction coefficient, the better the lubricity.Third, good chemical stability and resistance to erosion: Graphite has good chemical stability at room temperature, not subject to any strong acid, strong alkali and organic solvents; the carbon atom in the graphite layer is firm Combining, the surface of graphite phosphorus can be very low, not moisturizing by melting furnaces, and strong resistance to erosion. However, graphite is prone to oxidation in the air, and anti -oxidation mea

The case of graphite boat is harmful to the proportion of the surface layer

The harm of the shape of the graphite boat to the surface layer of the surface layer will use the new graphite boat and the use of the old graphite boat for more than three years to saturate the coating on the surface layer of the PECVD surface. The flat surface of the new graphite boat is good, and the graphite boat has the same conductivity. The plastic membrane molecular formula can be uniformly accumulated on the surface of the single crystal silicon wafer, and the uniformity between the pieces is higher.After the new graphite boat is saturated, there are still some plasma accumulated on the graphite boat when the accumulation is accumulated. When the number of running times is less than thirty times, as the number of running times increases, the plasma accumulated on the graphite boat decreases. Essence After the number of running times exceeds thirty times, as the number of uses increases, the inner wall of the graphite tape and the single crystal silicon tablets touch the plast

The Future Market Prospects of Graphite Powder

Graphite product form

(1) High pure graphite

Graphite mold for antioxidant treatment

1. Heating and conductive: The heterogeneity of graphite is 300 times that of the normal non -non -non -metal mine. Conductivity surpasses non -metal materials such as steel, iron, lead. The conductivity coefficient increased with a decrease in measure, and even at a high degree, graphite became armatologist.2. Chemical stability: Graphite is excellent chemical stability at normal temperature, and the erosion of acid, alkali resistance and inorganic solvents.3. Smooth: The smooth function of graphite originated from the size of the graphite scales. The larger the scales, the smaller the conflict coefficient, and the better the smooth function.4. Plasticity: The graphite is tough and can be crushed into a thin crack. 5. Taxation shock: Graphite can be banned violently at the time of normal temperature and can be banned violently without destruction. When the measurement gradually changes, the volume of the graphite is not large and no cracks will occur.6. Low temperature resistance: T

Artificial graphite application field

In the metallurgical industry, natural scales can be used to produce refractory materials such as magnesium carbon bricks and aluminum carbon bricks due to better antioxidant properties. Artificial graphite can be used as a steelmaking electrode, and the electrodes made of natural graphite are difficult to use to use the steelmaking electric furnaces with strict conditions.In the machinery industry, graphite materials are usually used for wear -resistant and lubricating materials. The lubrication of natural scales graphite is better, which is often used as additives for lubricating oil. The device that transports the corrosive medium is widely used by artificial graphite pistons, sealing rings and bearings. There is no need to add lubricating oil during work. Natural graphite and polymer resin composite materials can also be used in the above fields, but wear resistance is not as good as artificial graphite.In the chemical industry, artificial graphite has the characteristics of corro
