Color changing grease can be used to monitor the outflow of water from the anode or cathode bed, indicating the failure point in a timely manner when the anode or cathode bed is about to fail. It is an intuitive and effective supplement to online monitoring instruments. It has the advantages of stability, reliability, ease of use, and non polluting water quality.

Color changing cation exchange resin is a type of cation exchange resin with an indicator. The factory type is hydrogen type, and if the water in the color changing cation exchange resin containsNa+TheK+TheCa2+TheMg2+TheFe2+When waiting for various cations, it is carried by the resinH+Exchange occurs, the resin layer begins to fail, and the color of the failed layer changes significantly, indicating the leakage of cations in the water.H+When the type is dark green,Na+When the color is purple, the color difference of the product is very obvious. It also has good exchange capacity and physical stability.

Color changing cation resin is generally used in condensation water, deaerator, economizer, main steam, etc. of thermal power plantsH+Before the conductivity meter, remove the free ammonia introduced into the water and convert all cations intoH+Ions, avoidingCa2+TheMg2+TheNa+The phenomenon of leakage into condensed water and a decrease in the displayed value of the conductivity meter.

Color changing cationic resin andH+The conductivity meter is used in combination to monitor whether the leakage of the condenser exceeds the standard, determine whether the condensate needs to be treated, and monitor whether the quality of the feedwater and steam meets the standard requirements. It is an important and relied upon chemical meter for chemical supervision in thermal power plants.

Application scope of color changing resin: Monitoring and controlling the hydrogen conductivity of feedwater, condensate, and steam is an important means to ensure the quality of water vapor and control corrosion and scaling in the water vapor system of thermal power plants.

Due to the frequent changes in ammonia concentration and sampling flow rate in water vapor, as well as factors such as unit start-up and shutdown, it is difficult to determineHWhen will the exchange column fail.HIn the initial stage of failure of the type exchange column, due to the penetration of a small amount of ammonium ions, the measured hydrogen conductivity value is low; WhenHThe type exchange column failed, causing a large amount of ammonium ions to pass through, and the hydrogen conductivity measurement value was also high. Therefore, when the failure of the exchange column causes a change in hydrogen conductivity, it is difficult to timely determine whether it is due to water quality deterioration or exchange column failure. Using color changing cation exchange resinCan solve this problemThe color of the failed layer is different from that of the non failed layer, and can be used inHTimely regeneration treatment before the failure of the type exchange column can detect water quality deterioration problems in a timely manner and take timely measures to solve themThis avoids the blindness of resin replacement, improves the efficiency of resin use, and ensures the reliability and effectiveness of hydrogen conductivity detection.

Color changing resinregenerationMethod:

（1）Load the cleaned resin into the actual exchange column at a minimum of10Double the volume of resin5%HClDynamic countercurrent regeneration of regeneration solution (opposite to the flow direction of the exchange column), regeneration flow rate control3m/h～5m/hEnsure that the contact time between the regeneration solution and the resin is not less than30min；

（2）After the regeneration solution is completed, rinse the exchange column with desalinated water in the direction of the flow of the exchange column with a large flow rate (flushing flow rate)10m/h～20m/h）.

（3）The regenerated and cleaned hydrogen exchange column can be installed into the actual system for measuring hydrogen conductivity.

（4）The failed color changing resin hydrogen exchange column can be directly regenerated.

Storage of color changing resin:Resins that require long-term storage should be regenerated into hydrogen type resins before storage.
