What is the code for resistivity?

Released Date: Apr 22,2016 Article Source: Yuanlai Water Treatment

What is the code for resistivity? When determining the electrical conductivity of water, it is related to the size of the water's resistance value. A large resistance value indicates poor electrical conductivity, while a small resistance value suggests good electrical conductivity. According to Ohm's Law, when the water temperature is constant, the resistance value R of water is inversely proportional to the vertical cross-sectional area F of the electrode and directly proportional to the distance L between the electrodes, as shown in the following formula: R=ρ. In the L/F formula, ρ represents resistivity, or specific cathode. The unit of the cathode is the ohm (Ω, code: Ω), or microohm (μΩ), with 1Ω equal to 106μΩ. The unit of resistivity (SI) is the ohm (Ω · m). If the cross-sectional area F of the electrode is made as 1cm ² and the distance L between the two electrodes is 1cm, then the resistance value is equal to the resistivity. The resistivity of water

　　What is the code for resistivity?

　　When determining the electrical conductivity of water, it is related to the size of the water's resistance value. A large resistance value indicates poor electrical conductivity, while a small resistance value suggests good electrical conductivity. According to Ohm's Law, the resistance value of water at a constant water temperatureRThe size is related to the vertical cross-sectional area of the electrodeFIt is inversely proportional to the distance between the electrodesLIt is directly proportional, as shown in the following formula:R=ρ·L/F In the formulaρ--Resistivity, or specific cathode. The unit of the cathode is the ohm (ohm, code)Ω), or use micro-ohmμΩ"1ΩEqual to106μΩ; The system of resistivitySIThe unit is ohm.Ω·m "

　　If the cross-sectional area of the electrodeF"Accomplished"1cm2The distance between the two electrodesLfor1cmThen the resistance value is equal to the resistivity. The magnitude of water's resistivity is related to the salt content in the water, the concentration of ions in the water, the charge number of ions, and the speed of ion movement. Therefore, pure water has a very high resistivity.Ultra-pure waterThe resistivity is even greater. The purer the water, the greater its resistivity.

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
