At the same time, we will provide necessary follow-up service assurance. We have D&B report and you could check details information for our company.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible.

Q:I remember the more lively metal, the electron?: C is a salt solution of copper metal because copper is first reduced to a single element on a graphite electrode.Moreover, the addition of dilute sulfuric acid has a H2 emission, then a H of the previous metal.

Q:Electrolysis of CuCl2 solutions with graphite electrodes: CuCl2 refers to a copper chloride ionization ionization ion and chloride ion in aqueous solution, the equivalent of CuCl2 does not exist, but there are only Cu2+ and Cl-, even if there is no electricity, the ionization will happen, because this is the nature of it.

Q:What is the difference between pyridine type nitrogen and graphite type nitrogen?: The fine structure graphite is the raw material used in the production of graphite electrode. The particle size is relatively small, generally below 0.5.

Q:Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution: Graphite as anode, generally do not need special treatment, but to choose high purity, high density, high strength (so-called "three high" graphite) graphite on the line, this graphite in brush plating operations are often used as anode material.

Q:What is the difference between SGL graphite electrode and graphite electrode in general?: In fact, the graphite electrode abroad (including Japan) in several ways than we can control the fine, one is pure, another is anisotropic (resistance, thermal conductivity ah) usually do some control, in the strength of domestic now is also doing well, but when we are comparing high quality products, general domestic products it is basically a piece of the indicators are poor

Q:Graphite electrode press device: Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.

Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?: Aqueous solution electrolytic cell has no diaphragm and diaphragm. Two kinds of commonly used diaphragm electrolyzer. In chlorate production and mercury method to produce chlorine and caustic soda, with no diaphragm electrolyzer. Try to increase the surface area per unit volume, can improve the production strength of electrolytic cell. Therefore, the modern electrode diaphragm electrolyzer the vertical components due to internal electrolysis. The material and structure and installation of different performance and different characteristics.

Q:What is anodized graphite?: According to the production method of brush, there are two kinds. One is colored brush, that is, metal graphite brush. One is black brush. The black brush is made of petroleum coke, pitch coke, carbon black, charcoal and natural graphite powder and so on. Some binders (such as coal tar pitch, coal tar and artificial resin etc.) are added to the black brush. The resin binder by curing brush manufactured for high resistance brush, and the calcined product called carbon brush and graphite brush (with natural graphite as the main raw material) graphitised after product called electrographite brush,

Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?: In addition, the infiltration of water on graphite is not good, can not get the effect of dust removal. Now there are special graphite machine, sealing system. Air-cooled can be used, after all, the best air-cooled.

Q:How to solve the problem of graphite electrode being crushed during electrolysis: I can only use the experience of the past to tell you that if you want to save money easily, the time can be considered as the costA thick graphite stick; inexpensive
