Abstract

PROBLEM TO BE SOLVED: To provide a fluid for removing contaminants which is mild to the substrate and can remove the contaminants from the substrate at good efficiency and a process for producing the same. SOLUTION: This invention provides a fluid for removing contaminants which is prepared by adding sodium carbonate, potassium hydroxide and metallic silicon to water and reacting the mixture and a process for producing the same which comprises adding 10-30wt.% metallic silicon, 6-10wt.% sodium carbonate and 5-10wt.% potassium hydroxide to 50-80wt.% water and reacting the mixture at 60-90 deg.C for 2-5hr.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning solution for contaminants for cleaning the surface of wooden building materials and other materials, and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, a cleaning solution containing sodium hydroxide and various other soaps has been used for removing a building.

[0003]

Problems to be Solved by the Invention Among the above-mentioned conventional cleaning liquids, those having a good cleaning action are liable to damage the skin of a tree, and there is a problem that dirt which has soaked into the grain cannot be removed.

[0004]

According to the present invention, water, sodium carbonate, and potassium hydroxide are reacted under the influence of metal silicon, so that the present invention has a slow effect and is capable of dissolving various wastes. An excellent detergent was obtained.

[0005] That is, the invention of a product is a cleaning solution for contaminants, wherein sodium carbonate, potassium hydroxide, and metal silicon are added to water and reacted.

[0006] The invention of the method is that 50% to 80% (by weight) of water, 10% to 30% (by weight) of metal silicon, 6% to 10% of sodium carbonate and 5% by weight of potassium hydroxide.
% To 10% (weight), and mixed at 60 ° C to 90 ° C for 2 to 5%.
A method for producing a contaminant washing liquid characterized by reacting for a period of time.

In the present invention, if the amount of metal silicon is less than 10% (weight), the reaction becomes insufficient and
It has been found that even if it is 0% (weight) or more, the improvement of the catalytic effect cannot be expected. Therefore, the amount is set to 10% to 30% (weight).

Next, the amount of water and the amounts of sodium carbonate and potassium hydroxide are related to the concentration of the product liquid. The effect is reduced when the amount of water is large, and the effect is reduced. When the amount of water is small, the effect is increased. Since there is no improvement of water, the amount of water is 50% ~ 8
0% (weight).

In general, when the degree of contamination is severe, a strong washing solution is used, but it is more effective to increase the number of washings at the same place.

The amount of metal silicon is related to the speed of the reaction. When the reaction time is 2 to 5 hours, usually 10% to 30% (by weight) of the total amount of the reactants is used.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, water is reacted with sodium carbonate and potassium hydroxide through metal silicon. According to the present invention, it is possible to obtain a detergent that is gentle on the skin of a tree and has a high cleaning ability.

[0012]

Example: 30 kg of water, 10 kg of metal silicon,
After adding 4 kg of sodium carbonate and 3.5 kg of potassium hydroxide and reacting for 4 hours, and filtering the solid matter, the washing liquid 1
5 liters were obtained. The temperature during the reaction is 60 ° C to 80 ° C
Met.

[0013] The cleaning solution obtained above is applied to a pillar or the like to be washed off (usual procedure for ragging) and left for 2 to 5 minutes, so that dirt comes up. Then 2
If it is repeated three times, not only the surface of the pillars and the like but also the surface soil will be raised, and the treated surface will be as clean as it can be.

Then, after washing with water to remove the washing liquid, a wax or other surface finishing liquid is applied to complete the removal processing. In the above, although there is no restriction on the usage amount of the cleaning solution, an appropriate amount is about 50 g / m ^{2 to} 70 g / m ² .

[0015]

According to the present invention, not only is it effective in removing dirt adhering to not only wood but also synthetic resins, metals and the like, but it has a slow action on the material to be treated. There is no danger of damaging the material, and in the case of wood and the like, there is also an effect of lifting the infiltrated dirt.

Claims (2)
