Product Description:

Introduction:

The nature graphite mining is lacated in North Korea, we import the raw mining material and product the cargo in China. We gurantee the good quality and the cargo is exported in Korea and to Japan widely.

We produce the natural amorphous graphite powder of amorphous graphit ore material of lutang, in chenhzhou of china, where there is the biggest and best amorphous graphite deposit all over the world.
The natural amorphous graphite powder is widely used in foundry, coating ,battery, electricity conductive material and so on. 


Usage:

(1)Mainly used in pencil making, graphite emulsion for welding rod burden of graphite axle, raw material of battery carbon rod.

(2)Mainly used in Coating in casting refractory material, dye electrode compound, etc.

(3) Mainly used as carbon additive in steel plant, to adjust the content of C in steel.

Q:Carbon emissions trading stocks latest list of carbon emissions trading stocks what?
Carbon trading concept of a total of 21 listed companies, of which 12 carbon trading concept listed companies trading on the Shanghai Stock Exchange, and 9 other carbon trading concept listed companies trading in the Shenzhen stock exchange.Automatic matching based on the cloud financial leading excavator, carbon trading stocks leading shares most likely from the following stock was born in Tianke, electrical, environmental protection up to confidence.
Q:What's the difference between lead and carbon?
No one is the same. Lead is poisonous, and pencil lead is lead. The structure of carbon is the same as that of diamonds. Generally speaking, they are of structure, density and composition. No one is the same
Q:How do you stick carbon fabric?
6, maintenance(1) after sticking the carbon fiber cloth, it is necessary to conserve 24h naturally to reach initial curing, and ensure that the curing period is free from interference(2) before each process, the resin should be covered with plastic film before it is cured so as to prevent sand or rain from attacking(3) when the temperature of the resin curing is reduced to less than 5 degrees, low temperature curing resin can be adopted, or effective heating measures can be adopted(4) CFRP after natural curing required to meet the design strength of time: the average temperature is 10 DEG C, 2 weeks; the average temperature is 10 degrees centigrade above 20 DEG C, 1 to 2 weeks; the average temperature is higher than 20 degrees in 1 weeks. During this period should be to prevent the patch part by the hard impact.7. PaintingThe coating shall be done after the initial curing of the resin and shall comply with the relevant standards and construction requirements for the coating used
Q:DNF advanced furnace rock carbon how, now more than +10 to advanced ah, how to get ah, 5
Higher carbon is a little more likely than colorless reinforcement. Kylie, there are 2 kinds of reinforcement. The strengthening above requires only a colorless color
Q:What are the benefits of carbon fiber?
Carbon fiber has many excellent properties, carbon fiber axial strength and high modulus, low density, high performance, no creep, non oxidation under the environment of high temperature resistance, good fatigue resistance, between heat and electrical conductivity between the metal and non metal, smaller thermal expansion coefficient and anisotropy, good corrosion resistance, X Radiability good. Good conductivity, thermal conductivity, good electromagnetic shielding, etc..Compared with the traditional carbon fiber glass fiber, the young's modulus is more than 3 times; compared with Kevlar fiber, the young's modulus is about 2 times in the organic solvent, acid and alkali insoluble swelling, outstanding corrosion resistance.
Q:What is the effect of carbon equivalent on welding?
The carbon equivalent of less than 0.4%, good weldability; in 0.4~0.6%, poor weldability, welding preheating and other measures to prevent cracks; more than 0.6 words, when welding needs higher temperature and strict technical measures! PS: carbon equivalent =C+Mn/6+ (Ni+Cu) /15+ (Cr+Mo+V) /5, Q235 carbon content in 0.14%~0.22% between, widely used by the company seems to be Q235B, carbon content between 0.12~0.20%
Q:What are the differences between the three carburizing, nitriding and carbonitriding? What are the different effects on the material?
Carbonitriding is the method of treating the surface of steel parts at the same time, penetrating the carbon atoms, nitrogen atoms of the river, forming the carbonitriding layer, so as to improve the hardness and wear resistance of the workpiece and to improve the fatigue strength of the river
Q:Carbon injection molding machine heating several degrees
The nozzle temperature is 260~310 degrees, and the temperature control of the two types of injection molding machine nozzles is different. The mold temperature has great influence on the mechanical properties of the products. With the increase of mold temperature. The temperature and the temperature difference between the temperature decreases, the shear stress decreases, can melt in the mold cavity slow cooling, the molecular chain orientation to relaxation reduced, thereby reducing the internal stress of products, but the impact strength and elongation of the products decreased significantly, while there will be demolding. When demoulding, it is easy to deform, prolong the molding cycle and reduce the production efficiency, while the lower mold temperature will increase the internal stress of the product. Therefore, the die temperature must be controlled. Normally, the mold temperature of PC is 80~120 degrees centigrade. Ordinary products are controlled at 80~100 degrees, while for complex shapes, thin walls and high requirements, the product is controlled at 100~120 degrees centigrade and is not allowed to exceed its thermal deformation temperature. Mold temperature control is particularly important when forming PC thick wall products.
Q:Advantages of carbon fiber
Carbon fiber axial strength and high modulus, no creep, fatigue resistance, between heat and electrical conductivity between the metal and non metal, low thermal expansion coefficient, good corrosion resistance, low fiber density, good permeability of X ray.
Q:What is carbon coffee fiber?
Its main functions are bacteriostasis, deodorization, divergence of negative ions and anti ultraviolet rays.
