Waxing as the first generation of stone care technology is still widely used today. This technology relies on water-bearing low-molecular-weight plastic materials to form a protective layer on the surface of the stone. But the waxing hardness is very low, it is easy to change color, it needs to be polished and waxed frequently, it consumes huge resources, and because wax is an airtight sealant, after the wax is burned, although the outside water and moisture can not enter the stone interior, you can Prevent pollution to a certain extent, but the moisture inside and below the stone can not be emitted due to the influence of the sealing wax, so that the water vapor accumulated in the interior of the stone for a long time, which will lead to the stone disease; and the wax generally affects the natural color of the stone, and at the same time Frequent waxing can damage the surface of the stone and shorten the life of the stone. Therefore, developed countries in Europe and the United States basically do not use waxing to maintain the stone, but use stone curing agent.
The main principle of stone protection is that the effective substance in the protective agent penetrates into the interior of the stone with the solvent. After the solvent is naturally volatilized, the effective substance and the stone crystal combine to form an effective protective barrier under the stone surface to prevent the infiltration of external and internal pollution. To achieve the purpose of protecting the stone and extending the life of the stone. Because the water absorption rate of the protected stone is greatly reduced, it can be said that it hardly absorbs water; as long as the water does not penetrate into the stone, the pollution will not be produced.
The protected stone has the following characteristics: waterproof, anti-fouling, anti-ultraviolet (delaying the fading time of the stone), anti-freezing, anti-solubility, maintaining the permeability of the stone, and reducing the difficulty of daily maintenance.
