1 demineralized water
Demineralized water refers to water hardness (mainly refers to the water calcium, magnesium ions) to remove or reduce a certain degree of water. In the process of water softening, hardness is reduced, and total content.
2 salt-removed water
Refers to the salt water desalination (mainly is soluble in water electrolyte) to remove or reduce strong to a certain degree of water. Conductivities generally 1.0-10.0 maximum tire-road friction coefficient S/CM, resistivity (25 ° c) 0.1-1.0 CM Ω M, salt, 1-5mg/L.
3 pure water
Water is refers to the strong and weak water electrolyte electrolytes (such as CO2, etc.) remove SiO2, or reduced to a certain degree of water. Conductivities generally for 10.0-0.1 maximum tire-road friction coefficient S/CM, resistivity (25 ° c) > 0.1-10.0 Ω M CM, salt, 1mg < / L.
4 ultra-pure water
Ultra-pure water refers to water almost completely remove conductive medium, also not the gas dissociation, colloid and organic substances (include bacteria, etc.) also remove to very low degree of water. The conductivity of 0.1 - general 0.055 maximum tire-road friction coefficient S/CM, resistivity (25 ° c) > 10.0 Ω M CM, salinity, < 0.1 mg/L. The ideal purified water (in theory) conductivity 0.055 for maximum tire-road friction coefficient S/CM, resistivity (25 ° c) for Ω M, 18.0 CM.
5 boiler water
Water boiler water is in a certain temperature and pressure produced by steam heating steam, heat and power as the medium. General industrial enterprise often USES low or medium heat boiler steam is produced by doing this or force of water boiler request slightly lower, While plants or thermal power plant boiler steam pressure produced often used to generate electricity, to promote the turbine steam turbine for guarantee of corrosion and scaling deposition, the boiler water requirement is very high. Therefore, the boiler water quality requirements according to the boiler work pressure and temperature varies, regardless of boiler water to water hardness, it is restricted. Other who can cause boilers, water supply system and other heating equipment corrosion and scale of smoke and soda and ion exchange resin poisoned impurities such as oxygen, soluble silica, iron and residual chlorine etc should be most or all away.
