Cation KU-2-8 Na

Cation KU-2-8 – non-combustible, infusible material, is not soluble and is not toxic. In physical form cation exchange resin ku-2-8 is a grain, spherical, able to swell and insoluble in water. Has a color from yellow to brown.

Cation KU-2-8 – it is a multifunctional silnokislotny resin. The main characteristic of the cationic resins is the presence in the composition of the acid groups, the hydrogen of which can be exchanged for the metal ions present in the solution.

Apply the cation KU-2-8 in water treatment process for water purification from impurities, for softening and demineralization of hard water, wastewater treatment on an industrial scale.

Main characteristics is stable to changes in osmotic pressure, high resistance against chemical and physical effects, a high degree of abrasion resistance of the granules to the action of oxidizing agents, alkalis, to thermal effects. Granules of the cation KU-2-8 are not washed out and do not dissolve in solutions and water. When interacting with water to swell. The process of softening and purification of water is carried out by passing it through a filter placed inside the cation. When filtering occurs, a chemical reaction in which ions of hard water are replaced with sodium ions (with Na — cation exchange). After that, the cation in the filter is regenerated, and after some time, the process can be repeated.

Storage warranty period – 1 year.

Packaging

Polypropylene bags of 20 kg.

Storage conditions

Cation KU-2-8 comes fully swollen in water. The cation should be stored in a moist condition at temperature not below +2°C in containers of the manufacturer in dry and clean warehouses. Loss of moisture during storage, the cation exchange resin is subjected to swelling in a 5-fold (20-24%) NaCI solution . 3-10 hours the solution is decanted and the resin washed several times with water. The freezing of the cation has no effect on its properties. In the case of freezing it is necessary to provide the possibility of gradual thawing at room temperature. During thawing to avoid mechanical
effects on the product.

Recommended operating conditions

Before starting work re-loaded cation exchange resin should be thoroughly washed with reverse current of water until, until the escaping fluid will not be transparent.
The water entering the cation exchanger should be as cleaned from suspended and colloidal particles, oils. Oil, suspended and colloidal particles envelop the surface of the granules with a layer that prevents reaction of ion exchange, reduce exchange capacity and increase pressure drop in the filters.
Strongly acidic cation KU-2-8 in the hydrogen-salt form at 98-99% is in the hydrogen form. For stable operation of the cation exchanger over a long period is recommended in the first and subsequent several cycles to disable the filter for regeneration, given the missed volume of water (10-15% above normal levels). This will eliminate sagitovna of cation and subsequent reduction of the filtration cycle.
The recommended way of loading the cation exchanger with manual or hydraulic. Pneumatic and vacuum transport will not allow, as it leads to cracking of the pellets.
