Embodiment Construction

[0009] The anti-corrosion treatment method of a fire-fighting water tank described in this embodiment is to apply an anti-corrosion coating on the inside of the water tank to electrically insulate the metal from the dielectric environment; several pieces of magnesium or magnesium alloys are uniformly installed inside the water tank As the anode, the iron plate of the tank itself is used as the cathode, and water is used as the electrolyte to polarize the entire structure to form a secondary corrosion battery. In this process, the surface of the anode shows an oxidation reaction. The magnesium or magnesium alloy used here Gradually consumed during the process, the surface of the cathode shows a reduction reaction, and the corrosion rate of the iron plate of the water tank is greatly slowed down or stopped, thereby being protected.

Abstract

The invention relates to an antiseptic treatment method for a fire-extinguishing tanker, which comprises the following steps: coating an antiseptic coating on the inside of the water tank, which is used for electrical insulation between a metal and a dielectric environment; uniformly arranging a plurality of magnesium or magnesium alloy blocks serving as anodes in the water tank; taking an iron plate of a tank body serving as a cathode; taking water as an electrolyte; and polarizing the whole structure to form a secondary corrosion battery. The method has the advantages that: the method combines cathodic protection technology and the coating, wherein the cathodic protection can effectively prevent corrosion caused by a damaged part of the coating and prolong the service life of the coating, and the coating can greatly reduce the demand quantity of a protection current, improve the distribution of the protection current, increase a protection semidiameter and ensure that the cathodic protection becomes more economic and effective and the whole process becomes safe and harmless; and the method effectively overcomes the shortcoming of leakage at a weld of the fire-extinguishing tanker, has simple operation and good safety, and is stable, reliable, and convenient to be popularized and applied.

Description

technical field [0001] The invention relates to the field of anticorrosion, in particular to an anticorrosion treatment method for a fire-fighting water tank. Background technique [0002] In addition to being equipped with fire-fighting water pumps and equipment, the water tank fire truck is also equipped with large-capacity water storage tanks, water guns, water cannons, etc., which can transport water and firefighters to the fire scene to fight fires independently. It can also be used from water sources. It can absorb water directly for fire fighting, or supply water to other fire trucks and fire extinguishing spray devices; it can also be used as a water supply and water delivery vehicle in water-shortage areas, suitable for general fire fighting, and is a standing fire fighting vehicle for public security fire brigades and full-time fire brigades of enterprises and institutions. . [0003] Metal corrosion, according to its reaction characteristics, can generally be div...
