Industrial boilers magnetized water processor functions and uses (1) anti-scaling effect of water entering the boiler has a certain flow rate through the magnetic field lines of cutting, a certain charge and make EMF charge movement, become magnetized water, but also with impurities in the water the charge generating a potential to become a polarized material, changing the state of the impurities of the original electrostatic attraction, thereby preventing the crystallization of calcium scale in water type, magnesium ions and other impurities produced by ionic binding of gravity, but the formation of easy-to-assemble and precipitated crystals were soft, avoiding fouling of boiler heating surfaces and pipes, to achieve the purpose of scaling. (2) oxygen rust preservative enters the boiler water through magnetization, oxygen molecules in water by a single water molecule inclusion, dissolved oxygen becomes inert oxygen, cutting off the oxygen required for the source of metal corrosion, rust played oxygen role. At the same time due to the overhang of composite high frequency electromagnetic wave modulation frequency electromagnetic fields generated aroused "skin effect", gathered in the heating surface negative charge excess, continue to attract iron ions in water to prevent metal wall separating iron ions dissolved in water, so Fe203 original heating surface (red rust) reduction or generate black rust Fe3O4 outer membrane is highly corrosion resistant force. In addition, it will produce hydrogen ions when water is magnetized in the heat because they have a good surface to form a protective effect of hydrogen ion coating, metal containers and pipes can play a very good anti-corrosion effect. (3) Since the cleaning effect of the water absorption of a number of the excited electrons, the dipole moment of water increases, the formation of particles with a high potential, can be effective to heat the metal surface and the soft scales fall off the existing pipe, and then to cleaning effect. (4) The role of water sterilization after the destruction of the biological cells magnetized ion channels, changing the water microorganisms, biological growth environment, to the loss of living conditions, which play the role of sterilization.
