How to replace the graphite copper?

a@b.com (Graphite) — Thu, 25 Dec 2008 13:31:54 +0800

In the 1960s, as a copper electrode materials are widely used, the utilization rate of about 90%, graphite, only about 10%; the 21st century, more and more users began to choose as a graphite electrode materials in Europe, more than 90% The graphite electrode materials. Copper, which had been dominant electrode materials, graphite electrodes and its advantages compared to almost disappear. What led to this dramatic change? Of course, is that a lot of advantages Graphite electrodes.

Graphite, the "flying" out of diamond

a@b.com (Graphite) — Thu, 25 Dec 2008 10:31:53 +0800

Diamond filed, people will think of the dazzling, flashing bright scenes, as the owner of the dazzling activities. But its expensive price, most people can only be discouraged. Nevertheless, people still long for the diamond. You know the diamond is? It is the chemical composition of carbon (C), natural diamonds by the diamond after pondering before described as "diamonds." Natural diamonds are very rare in the world is greater than the weight of 1000 kt (1 gram = 5 carats) of diamonds, only 2, more than 400 karats of diamonds, only more tablets, so far China's biggest diamond found in heavy 158.786 kt, which "Chang Lin Diamond." Scarcity, because to do, "Diamond" natural diamond is rare, people wanted to "artificial" diamond to replace it, and this naturally thought of Diamond's "twin" brother - the graphite.

First, carbon and graphite products
(A) of the type of graphite electrodes
Mainly petroleum coke and needle coke as raw materials, coal for asphalt binder, calcination, the ingredients, mixed pinch, pressure-type, roasting, graphite, machine processing and made in the electric arc furnace in the form of electric arc furnace charge for the release of energy For the melting heat conductor, according to the quality of their high or low, can be divided into ordinary power, high-power and ultra-high power. Graphite electrodes are:

Industrial Classification of natural graphite

1. Dense crystalline graphite
Dense crystalline graphite block, also known as graphite. Such graphite crystal clear crystals visible to the naked eye. Particles larger than 0.1 mm in diameter, surface area on the scope of the 0.1-1m2 / g (F-Sorb 2400 Miriam BET surface area method of testing), arranged in crystal chaotic, massive structure was dense. This: The graphite is characterized by high grade, generally for the carbon content of 60 to 65 percent, sometimes up to 80 ~ 98%, but the creamy and plasticity of graphite flake as well. Graphite surface area is a very important study, graphite surface area of the test data is only detected by BET using the results are real and reliable, there are a lot of domestic equipment can only do a direct comparison method of detection, are also being eliminated. At present, domestic and specific surface area test unified multi-point BET method, at home and abroad to develop specific surface area measured by the standard testing methods are based on BET-based, reference is made to our national standards (GB / T 19587-2004) - gas adsorption BET principle Determination of solid material surface area. Detection of specific surface area is relatively time-consuming work, as the absorption capacity of the sample, some of the test samples may need to spend a full day, if the test did not achieve a fully automated process, and that testers can not leave on time and to A high degree of concentration, observation instrument panel, the control knob, a little inattentive when the testing process will lead to the failure of this test would be a waste of a lot of staff time. Real fully automated intelligent surface area product testing, test equipment industry will be in line with international standards, similar international products are all fully automated and manual equipment abroad have been eliminated. Real fully automated intelligent surface area analyzer, the test will be repeated from the mechanical operation of liberating greatly reduced the intensity of their work, simple training to improve work efficiency. Real fully automated intelligent meter surface area, greatly reducing the human error led to the operation, improve the accuracy of the test. F-Sorb 2400 surface area than the real test is to achieve BET method of detection equipment (both direct contrast) and, more importantly, F-Sorb 2400 test surface area is so far the only fully automated intelligent than the surface area of detection Equipment, the test results with the international high consistency, stability is also very good at the same time to reduce human error and improve the accuracy of test results.

Graphite carbon element is the crystallization of minerals, and its crystal framework for the layered hexagonal structure. Each network layer between the distance of 3.40, the same network layer of carbon atoms in the pitch for 1.42A. A six-crystal system, complete with layered cleavage. Cleavage face key elements to focus on the weak molecular attractive, so Natural floatability of its very good.
