Method for removing ink smudges of stone wall space floor tiles and reagent

Abstract

The invention discloses a method for removing ink smudges of stone wall space floor tiles. The method includes the following steps that a lacquer thinner is sprayed onto the ink smudges of stone; ink already dissolved on the surface is wiped clean at once; the lacquer thinner is sprayed again; part of dissolved ink is wiped clean again; a sodium hypochlorite solution with the concentration being 6%-12% is smeared; wiping is performed; the solution on the stone surface is wiped clean; the sodium hypochlorite solution with the concentration being 6%-12% is smeared once again, so that the sodium hypochlorite solution is air-dried; and the process is completed. The invention further discloses a reagent adopted in the method for removing the ink smudges of the stone wall space floor tiles. The reagent comprises two parts of the lacquer thinner and two parts of the sodium hypochlorite solution with the concentration being 6%-12%. By means of the removing method and the reagent, the ink smudges placed on the stone surface or permeating into the stone can be removed, and the ink smudges can be removed thoroughly. Moreover, the stone surface cannot be damaged and corroded at all, and the natural color of the stone is restored. The method for removing the ink smudges of the stone wall space floor tiles and the reagent are further suitable for removing other kinds of ink smudges.

Description

technical field [0001] The invention relates to a method and reagent for removing ink stains, in particular to a method and reagent for removing ink stains of stone wall and floor tiles. Background technique [0002] For walls and floors contaminated by ink stains, washing and auxiliary agents such as washing powder, detergent and organic solvents are generally used to remove them, but the effect is limited, especially for stains that have penetrated into the stone pores. Conventional methods and conventional reagents have no effect at all; if strong alkalis and strong acids are used to remove them, they will be very destructive to the surface material of the stone, and the effect is not obvious. It will cause surface gypsum damage to the stone, and during the operation process, thick smoke will billow, irritate the throat and nose, and easily cause corrosion to passing pedestrians, which poses a great safety hazard; if using such as chloroform, carbon tetrachloride, di Tol...

Problems solved by technology

[0002] For walls and floors contaminated by ink stains, washing and auxiliary agents such as washing powder, detergent and organic solvents are generally used to remove them, but the effect is limited, especially for stains that have penetrated into the stone pores. Conventional methods and conventional reagents have no effect at all; if strong alkalis and strong acids are used to remove them, they will be very destructive to the surface material of the stone, and the effect is not obvious. It will cause surface gypsum damage to the stone, and during the operation process, thick smoke will billow, irritate the throat and nose, and easily cause corrosion to passing pedestrians, which poses a great safety hazard; if using such as chloroform, carbon tetrachloride, di Toluene and other strong organic solvents are used to remove the organic color that has penetrated into the stone, which is difficult to remove, and it is extremely polluting to the environment and extremely harmful to the health of operators and pedestrians.

Therefore, there is currently no method and reagent for efficiently removing ink stains that penetrate into stone wall and floor tiles without harming health and environmental pollution
