Graphite Cathode Protection With Low Porosity

Graphite Cathode Protection With Low PorosityProduct descriptionGraphite rod is impregnated,Website:http://www.tennrycarbon.com, reduce the surface porosity, separate the metal basal body from outside surrounding, avoid metal to act on surrounding, thus get the anti-corrosion effect.Anode protection is the anti-corrosion technology that exert the positive polarity current to metal, produce a protective membrane on the metal surface, get the effect of protecting metal.  The reason for electrochemical corrosion: because of the difference of physical and chemistry property in ground, any part of pipe has the different metallurgical structure, such as impurity, internal strain, difference of surface roughness, make some metal ionize easily, with positive electricity metal ion leave for the metal and transfer into the field, there are less and less electron in this part of pipe, electric potential becomes negative, but another part of metal is not easier to ionize, so electric potential is positive. The electron flow from the easier ionize part to not easier ionize part, between these two part metal happen the oxidation and oxidation reduction reaction. The part of metal which is lost the electron becomes the positive column, getting electron part will become the negative polarity zone. Corrosion current flow from negative pole to positive, then leave for pipe metal from the positive pole, through the field and come back to negative pole, form the return circuit. In the field which as the electrolyte liquor happen the ion moving, cation move to the negative pole, anion move to the positive pole, in positive column, metal ion with positive electricity react with anion, the metal ion in positive column are ionized and corroded unceasingly, then the surface of steel pipe will have the indentation that lead to boring a hole.AdvantagesAnode protection has a lot of exclusive superiority. The protection current exerted to the metal/ liquid medium usually equates with the dissolve current of protected metal under passivity status. So anode protection not only supply the anti-corrosion protection, but also a direct method that monitor the corrosion speed of to be protected system. By contrast, in many anti-corrosion technology, anode protection is developed so late, but it is a economic and efficient anti-corrosion technology. Using external power to anode polarization is the frequently-used method to protect anode. Company introductionQingdao Tennry Carbon Co., Ltd  is the professional manufacturer for graphite products in Shandong province.
