Description:

Calcined Petroleum Coke comes from delayed coke which extracted from oil refinery. Although Calcined Petroleum Coke contains a little bit higher level of sulfur and nitrogen than pitch coke, the price advantage still makes it widely used during steel-making and founding as a kind of carbon additive/carburant.

CHARACTERISTICS:

1.Low impurities.

2.High carbon absorptivity .The natural flake graphite is lubricative, it can be quickly dissolved in the liquid steel , and more than 96% of the carbon can be absorbed. It can save the smelting cost.

APPLICATIONS:

Used as an additive for raising carbon to correct levels in the manufacture of ductile, cast and synthetic irons. Similar application is also used in the manufacture of steel in steel mills.

Q: It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?: Suggestion: use a certain amount of concentrated nitric acid infiltrated graphite part, nitrate solution the best there is a certain amount of 1-2 weeks (timing can also be placed with a glass rod, pour stirred) acid, diluted with water to acid and then scrub brush. Because the temperature nitric acid reaction is very slow, but the long-term infiltration, the graphite surface. Especially with the glass contact surfaces may be immersed in a small amount of acid, oxidation, then scrub may have the effect.

Q: Can I use super fine stone powder in grease or lubricating oil?: Not really. It depends on the amount of graphite powder. If the graphite powder forms a continuous through zone, it can be considered a conductor.You can use lubricating oil, preferably not with graphite, which will cause the sliding rheostat to fail

Q: The principle of a graphite missile: When graphite sticks to point wires, numerous circuits are formed, but they are short circuited.So the circuit was broken.

Q: Classification of graphite powders: The classification of graphite powder can be divided into pure graphite, high carbon graphite, carbon graphite and carbon graphite with low carbon content, according to specifications into 50 mesh ~10000 mesh graphite, graphite powder in Qingdao Huatai use can be divided into graphene conductive graphite powder, graphite powder, graphite powder lubrication battery, graphite powder, ultrafine graphite, graphite powder, graphite nano colloidal graphite powder are the type of L.

Q: For thermal grease skills, the more detailed the better: But this is not possible, the metal lid heat sink and CPU looks smooth, but with a magnifying glass, you can see many holes in metal surface concave stripes and irregular tunnel, lead contact surface with many gaps, these gaps are impeding heat dissipation, thermal grease is liquid, can fill the gaps. Improved radiating surface contact, the heat dissipating effect than when there is no good thermal grease. But if the thermal grease is too thick, it will become a film on the contact surface of the middle, but hindered the direct contact of metal, worse than not coated with thermal grease.

Q: Is oxygen allowed in the oxygen pipe?: The so-called oxygen pipeline, which depends on the medical or edible, or industrial oxygen pipeline. If it is industrial, a little graphite is possible, but the proportion can not be too large

Q: What is the use of flake graphite in making flake graphite powder?: Flake graphite powder: natural crystalline graphite, the shape of fish like phosphorus, is a six party crystal system, layered structure, with good resistance to high temperature, conductive, heat conduction, lubrication, plasticity and acid and alkali resistance.

Q: How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways: Method three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectivelyIf bubbles are produced and green light is generated, the solution is iron powder (chemical equation Fe+2HCl = FeCl2+H2)The reaction is more intense, there are more bubbles, the color of the solution does not change, it is aluminum (chemical equation 2Al+6HCl = 2AlCl3+3H2)No obvious phenomenon is graphite powder (not reaction)(2) if the difference between the bubble phenomenon is not obvious, then two kinds of powder with magnetCan be the magnet is not attracted by the permanent magnet is iron powder; powder(high school can also use NaOH solution to identify iron aluminum, aluminum reacts to dissolve hydrogen, iron does not respond)

Q: Can graphite powder be used as a carburizing agent?: It is OK to use a machine that processes fish food with high carbon content,

Q: How can graphite paper be made? Can graphite powder be solidified without brittleness?: Single layer graphite paper is thin, thickness less than 1mm, strength is low, it is the raw material of electric heating felt and advanced gasket sealing material. It is widely used. The single graphite paper and multilayer plate are rolled into thick composite boardI hope it works for you
