preparation example 2

[0027] With the mass ratio of 100:35, 200 mesh diatomite and bentonite are mixed into powdery carrier, then with the mass ratio of 100:40, the powdery carrier is mixed with sodium percarbonate powder (active oxygen content 13%), then Measuring, dispensing and packaging to make the finished product of stone stain remover. When in use, mix stone stain removal powder with water at a mass ratio of 1:2.5-4 and stir to form a paste (or add water to stone stain remover and stir to form a paste), and apply it on the stain pollution on the stone surface.

preparation example 3

[0029] Mix 200-mesh bentonite and 300-mesh aluminum magnesium silicate into a powder carrier at a mass ratio of 1:1, and then mix the powdered carrier with sodium percarbonate powder (13% active oxygen content) at a mass ratio of 100:45 Evenly, then metering, subpackaging and packaging to make the finished product of stone stain remover. When in use, mix stone stain removal powder with water at a mass ratio of 1:2.2-4 and stir to form a paste (or add water to stone stain remover and stir to form a paste), and apply it on the stain pollution on the stone surface.

[0030] The following test examples are aimed at the common red wine stains, coffee stains, carton yellow (carton pollution traces), stains (iron-free yellow or brown or green that come out from the inside of the stone under wet conditions) on the surface of architectural decorative stones. stains) and rust spots, and the cleaning effect was compared with common stone types as substrates.

Embodiment 2

[0038] Wear a protective mask, mix 200 mesh diatomaceous earth and aluminum magnesium silicate powder with a mass ratio of 100:30 to obtain a powdery carrier at the stone stain removal site, and mix the powdery carrier with sodium percarbonate (active oxidation content 13%) ) according to the mass ratio of 1:0.4 mixed to clean the powder mixture. Then mix and stir the cleaning powder mixture and water according to the mass ratio of 1:3.2 to form a paste (the ratio of powder mixture and water can be measured or not, just add water and mix to form a paste).

[0039] Apply the above-mentioned mixed paste cleaning agent on the stain or pollution on the stone surface to form an application layer, the thickness of the application layer is about 3-6mm, and keep it for 120 minutes. During the period, observe the effect at intervals of about 20 minutes, and clean the application layer with a spatula or brush at 120 minutes. The effect description is shown in Table 2.

Abstract

The invention relates to a stone color spot removing method and a stone color spot removing agent. The method comprises the steps of mixing and stirring a liquid oxidizing agent and a powdery carrieron a stone color spot removing site to obtain a paste material, or mixing the solid oxidizing agent, the powdery carrier and water at the stone color spot removing site to obtain a paste material, ormixing and stirring the color spot removing agent composed of the solid oxidizing agent and the powdery carrier with the water at the stone color spot removing site to obtain a paste material; and then applying the paste material to stone color spots. The defects that in an existing stone cleaning technology, a stone color spot removing method has a long cleaning process time, a short action timeof a cleaning agent, an unstable cleaning effect and a complex process, and the agent has deflagration hidden danger, chemical burn and inconvenient transportation and storage and the like are overcome.

Description

technical field [0001] The invention relates to a stone stain removal method and a preparation for removing stone stains. It specifically relates to a method and material for removing difficult-to-handle decorative stains on the surface of architectural decorative stones by using an oxidant and an improved convenient process. [0002] technical background [0003] The surface of building decoration stone is often colored by red wine, tea stains or other foreign stains, resulting in color spots that affect the decoration of the stone; the stone will also be affected by moisture due to its own reasons, resulting in pan Yellow, brown or blue stains will affect the decorativeness of the stone. [0004] In the existing stone cleaning technology, it is recommended to use a cleaning agent containing hydrogen peroxide solution (hydrogen peroxide) to clean the polluted stains on the surface of the decorative stone and the lesion stains from itself, so the hydrogen peroxide solution i...
