②How to guarantee the quality of the products？
We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- Q: What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
- The first answer to the equation above is quite right, or it may be that a layer of calcium carbonate is attached to the surface of the electrode, which prevents the electrode from conducting and leads to an increase in resistance
- Q: Is the anode of electrolytic water suitable for ordinary titanium wires?
- The graphite is cheaper and easier to obtain, but the carbon electrodes sold in the general market are not very pure at most times. The experiment is done for a period of time, and the carbon is inexplicably broken, especially if you need to work for a long time. So, if your graphite electrode is of good quality, it's still graphite.
- Q: In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them
- Graphite is characterized by coarse particles, fine particles and ultrafine particlesFor different processing, you can choose different particles, the smaller the particle size, the higher the accuracyCopper has good conductivity and thermal conductivity and is used in many occasionsBut there are many factors to consider in the choice between the two
- Q: Graphite can be used in acid towers in chemical plants because of graphite
- The popularization and use of this technology can bring about such economic and social effects: (1) the consumption of graphite electrode units is less, and the production cost is reduced. For example, a steel plant, according to the annual production level did not occur in LF refining furnace 35 week graphite electrode, refining furnace 165 consumption calculation, using anti oxidation technology of graphite electrode, graphite electrode can save 373 per year(153 tons) electrode, each year ultra high power electrode 16900 yuan computation, can save 2 million 585 thousand and 700 yuan rmb.
- Q: The production of one ton of steel required graphite electrode
- Can not generally say, a ton of steel production consumes much of graphite electrode.
- Q: How should carbon deposits be treated?
- At certain temperature, can make alloy and carbon can react in the engine surface coated with a layer of graphene film, graphene nano particles can fill the pores, wear scratches, on the friction surface repair function.
- Q: Graphite electrode press device
- High power graphite electrodes. Graphite electrodes with a current density of 18 ~ 25A / cm 2 are allowed. They are mainly used in high power arc furnaces for steelmaking
- Q: What do carbon products include?
- Carbon and graphite materials are mainly carbon based non-metallic solid materials, in which carbon material is basically composed of non graphitic carbon material, and graphite material is basically composed of graphite carbon material. For the sake of simplicity, carbon and graphite materials are sometimes referred to as carbon materials (or carbon materials).
- Q: Electrolysis of CuCl2 solutions with graphite electrodes
- The energization is the electrolysis of CuCl2 solutions, i.e., redox reactions. So you can't mix ionization and electrolysis.
- Q: How large is the permissible overload current per square millimeter of the graphite electrode cross section?
- The safe current is decided according to the conductor wire cooling conditions, cooling conditions, the overhead line package, an insulating layer and bare, cooling conditions are also different.
