1. Polite boiler softening water resinC100EFGWork performance

Polite boiler softening water resinC100EFGThe softening system is related to the following factors:

1The total amount and concentration of the regenerant used.

2The total hardness and sodium ion content in the influent water.

3Operating flow rate.

The working performance is usually evaluated by the residual hardness in the treated water. For the softening system of tap water, due to the water quality requirements, a diversion treatment method of mixing thoroughly softened water with raw water can be adopted. For industrial applications, the hardness of the treated water should be less than5ppmThis is available.70-80kgNaCl/m3RFor the regeneration level, if the softened water is supplied to a common low-pressure boiler, the water quality requirement is that the hardness should be lower than1ppmIn this way, at least twice the above regeneration level is needed to meet the requirements. Under normal working conditions, the leakage hardness is usually lower than that of the incoming water hardness1%The working exchange capacity generally does not change much, unless the raw water contains it25%Sodium ions above concentration.

In civil softening systems, with relatively low regeneration levels, residual hardness is usually not required, and the impact of medium to high flow rate operation on the working exchange capacity can also be ignored. However, it is worth noting that to maximize the effectiveness of the regenerant, the salt concentration can be increased and the regeneration time can be extended. When the regenerant is in excess, the regeneration flow rate should also be slow, but the excess salt should be removed at the running speed.

Ii. Polite Boiler Softening Water ResinC100EFGChemical and thermal stability

C100EResin is insoluble in water, dilute or medium concentration acids, bases and other common solvents. However, if it is stored for a long time in an environment with a large amount of active chlorine, hypochlorite ions or other strong oxidizing solvents, its cross-linking will be destroyed, and the water content of the resin will increase, the strength will decrease, and a small number of decomposition products will also appear. Like all sulfonic acid-based styrene resins, its sodium form can withstand high temperatures under alkaline conditions1500CAnd the hydrogen form is higher1200CAt that time, it will lose its exchange capacity because its functional groups will gradually be replaced by hydroxyl groups.
