Description

A specific formulation which has an excellent cleaning efficiency already at very low dosing rates in alkaline solutions up to 30°Bé
(approx. 300 g/l NaOH). The non-ionic surfactants of KEBOPLEX SP do not work stoichiometrically, but wet and penetrate the deposits. Due to their small molecular size, they are able to penetrate and infiltrate the deposits and cause them to flake off. As a result, a very good cleaning effect is already achieved with a lower dosage. The additional dispersants and special surfactants can dissolve, soften, and remove organic residues, sugar carbon and organic sugar degradation products more quickly. They also prevent the re-accumulation of deposits formed on the evaporator surface.

Benefits

KEBOPLEX SP offers many advantages:

• The special combination of soft complexing agents and surfactants causes faster removal of the deposits from the metal surfaces
• The surface tension between the phases is reduced
• Silicates are dispersed which would otherwise not be removed
• The effectiveness of water jet or acidic cleaning is increased
• The redeposition and adhesion to the heat surfaces are prevented by the dispersants.

During chemical cleaning operations in the cane sugar industry the following advantages have proved a success when adding KEBOPLEX SP:

• The dissolution of sugar decomposition products and other inconvenient organic components (e.g. waxes from the cane, proteins and other gelatinous substances) in alkaline solutions is considerably improved and accelerated.
• At the alkaline treatment with NaOH solutions of different concentration and when adding 1 - 5 % sodium carbonate (Na₂CO₃) calcium compounds such as calcium oxalate, calcium sulfate a.s.o. being difficult to dissolve are transformed into acid soluble compounds by adding KEBOPLEX SP. As a result the treatment period is shortened.
• At rinsings with water the detached sludge can easily be removed. Consequently the requirement of acid at a subsequent acidification is considerably reduced.
• KEBOPLEX SP is even resistant to high temperatures and effective.
• It can be used for alkali concentrations up to approx. 30°Bé (25 %).
