Q:25%, the fracture of graphite rod, pressing problem or sintering problem?

25% graphite ratio is quite high, with the molding production difficult.1 could reduce the ratio of graphite to discuss it with the client? 2 in the mixture of additives (please forgive aids not at the forum released in 3) release to be coherent, there can be no pause

Q:What about the thermal conductivity of graphite rods?

The thermal conductivity and conductivity of the graphite rod are quite high. The conductivity of the graphite rod is 4 times higher than that of stainless steel, 2 times higher than that of carbon steel, and 100 times higher than that of ordinary nonmetal.

Q:Carbon fiber nylon bars differ from graphite rods

A carbon fiber conductive nylon nylon belongs to, is to add carbon fiber in nylon material. The carbon fiber component determines the strength and conductivity of the material. The conventional addition of 30% carbon fibers can reach 10 of the 3-6 sides, belonging to the conductive products. In addition, carbon fiber in addition to conductive, but also can play a wear-resistant role, the intensity will be greatly improved.

Q:What kind of sketch do you want, Shi Mobang?

No, it's about two or three yuan for a box and ten for two months. Graphite can be used instead.

Q:How good is the conductivity of graphite and the conductivity of copper?

It's copper. Copper resistivity is 10 negative, 8 times only after silver, and graphite resistivity magnitude is negative 6 timesGraphite rods are used in dry cells because they are stable in electrolytes, free of corrosion and low in industrial cost

Q:How many times will a high pure graphite stick turn red at temperature?

When the temperature reaches 400 degrees, the graphite turns red and then begins to oxidize, but the oxidation rate is slow.

Q:What is the difference between a graphite wand, a drawing pencil and an ordinary Chinese painting pencil?

Charcoal is the source of raw wood burning container was put into the seal, because the air can not enter the container, not wood burning down. Crunchy texture, porous charcoal, charcoal painting with hardness, very soft, soft, not soft not hard points.General charcoal are used to draft use, easy to modify, draw up very fast, so is generally not as deep drawing tools. The difference in the diameter of the charcoal strips is determined by the size and size of the paintings.

Q:What are graphite products mainly including?Specific points can understand

One of the main uses of graphite is to produce refractories, including refractory bricks, crucibles, continuous casting powders, mold cores, molds, detergents and high temperature resistant materials. In recent years, two important changes in the refractory industry is MgO-C brick is widely used in steelmaking furnace lining, and the application of aluminum carbon brick in continuous casting process. The graphite refractories and steelmaking refractories are closely linked, the world steel industry about consumption.

Q:What is the difference between the conductive effects of different grades of graphite? Refers to the pencil core

B is "black" (black) English prefixes, on behalf of graphite, is used to represent the case of soft pencil and write the obvious level. To "6B" for the most soft, the most black handwriting, often used in painting, ordinary pencil mark is generally "Hb."". The pencil mark used to cover the answer sheet during the exam is usually "2B""

Q:Bought a high pure graphite stick, how so hard?! Doesn't it say that graphite is soft? Why is it so hard?

The graphite is soft, refers to natural flake graphite powder, rather than artificial. Try some natural flake graphite powder.
