Method for cleaning an open pored surface with salt contamination

摘要

The method comprises applying a hydrophobic impregnation coating on an open-porous dry surface, feeding the hydrophobic impregnation coating into hydrophobized pores, spraying an aqueous acid solution, for 1-15 minutes, to a hydrophobic surface, where the acid solution removes a salt contamination within 15 minutes using a foam formation by cleaning the surface, rinsing the surface with the salt containing acid solution, and forming a dust-removing, good-grip, color-enhancing, open-pore impregnation with the components within few hours to maximum 3 days after applying the coating.

The impregnation coating is introduced into the pores via froth-breaking using a fatty alcohol having 14C in combination with an alkyl polyglycoside. The impregnation coating is neutral, and comprises a creepable, hydrophobic component, and a medicinal white oil. The applying step is carried out with the components in accordance with method consisting of fogging, spraying, splashing, brushing, rolling, flooding, foaming, printing, and dipping. The acid solution comprises foam-forming surfactants (5%), a mineral acid, a pH regulator for a range of 1-2, residual control, auxiliary material and/or unavoidable impurities.
