Most of the stone faces such a problem in the process of use: wear-resistant not bright, bright and not wear-resistant. Experience tells everyone that the harder the stone, the more wear-resistant it is. However, in the process of using decorative stone, it is impossible to replace the stone in order to accommodate the hardness or wear resistance of the stone.
Therefore, it is necessary to use stone surface treatment technology to improve the hardness and wear resistance of the stone. To solve the abrasion resistance of the stone surface, the principle that must be followed is that the stone surface should be bright. The surface of the stone is treated by a certain process to ensure both brightness and wear resistance. The wear resistance level can be roughly divided into four: the fourth degree of wear resistance : stone surface waxing process; the third degree of wear resistance : stone surface crystallization process; the second degree of wear resistance: physical polishing of the stone; the first degree of wear resistance: the glaze sealing process on the surface of the stone.
In the same wear level, there may be different treatment methods, but the principle, surface structure, material are similar, and the wear resistance is also similar. In the case of the same gloss, the abrasion resistance of the stone surface made by different processes is very different.
The fourth degree of wear resistance: stone surface waxing process
Wear resistance index: ★☆☆☆☆
As we all know, wax is organic. The wax is bright and has a good visual effect. It can greatly improve the gloss of the stone surface when used on the surface of the stone.
However, the wear resistance of wax is definitely not as high as that of stone itself, and its gloss will disappear after a period of time. Therefore, waxing is not recommended for the ground. Although the wax is bright, it is not wear-resistant.
The third degree of wear resistance: stone surface crystallization process
Wear resistance index: ★★☆☆☆
The so-called crystallization of stone is to polish the surface of the stone with a material rich in a certain amount of acid, fused with resin components. At present, the main materials of crystallization are crystalline powder and crystallization agent. Although the materials are different, the crystallization principle is not much different. The key link that crystal polishing can achieve is chemical reaction and resin filling. The main component of marble is carbonate. When it encounters acidic substances, it can react chemically to etch the bumps on the surface, and then use the resin component to fill and optimize the gaps on the stone surface to make the surface of the stone bright and transparent.
Therefore, the crystallization process, also known as the crystal hardening process, can not only increase the gloss, but also increase the hardness. Under normal circumstances, the crystalline layer has neither the high hardness of the stone structure nor the high wear resistance of the stone structure.
This chemical treatment process has certain shortcomings: chemical reactions and chemical materials have certain harm to the environment, the human body, and the stone itself;although the wear resistance of chemical grinding is higher than that of waxing, the crystalline layer is still a combination of organic matter and secondary minerals, containing high resin components, and low wear resistance, requiring repeated maintenance;in the daily use and maintenance process, the chemical crystal layer is prone to hydration reaction in contact with water, causing loss of calcium and loss of gloss.
The second degree of wear resistance: physical polishing of the stone
Wear resistance index: ★★★★☆
The stone itself is wear-resistant, but the stone itself is difficult to handle the light. It is not bright, but only wear-resistant, which is unacceptable for decorative stone. How to grind the glossiness of the stone itself is also a craft that everyone is looking forward to.In fact, the physical polishing of stone can be achieved in the stone processing plant, but the environmental requirements are relatively strict, such as high pressure, large area, and high flatness;However, at the construction and maintenance site, it is really difficult to achieve physical polishing with small machines such as single-disc machines.
The high-gloss surface of the stone made by this method of pure physical polishing is the mineral structure of the stone itself. The polished stone has a high-gloss surface and a dense primary mineral structure to prevent the intrusion of pollutants; the hardness of the stone mineral itself is much higher than the waxed layer and the crystal layer, and the wear resistance of the bright surface is also better than that of waxed and crystallized surfaces; The hardness and wear resistance of primary minerals are higher than secondary minerals that undergo crystallization reaction, and the color of primary minerals is superior.
The first degree of wear resistance: the glaze sealing process on the surface of the stone
Wear resistance index: ★★★★★
The main component of the glaze is silica, which is glass. The structure of silicon dioxide is dense, the chemical bond is strong and stable, and it is not easy to be destroyed. Glass is very wear-resistant, and the main components of the glass are integrated into the sealing material, and the wear resistance of the sealing glaze surface can be imagined. After testing, the wear resistance of the sealing glaze layer is higher than that of artificial quartz stone, not to mention marble and granite.
The glaze sealing technology is a physical coating technology with strong versatility. It is not only suitable for marble, artificial stone, limestone, etc., but also for granite, floor tiles, and even wood floors that cannot be chemically crystallized.
The glaze sealing layer acts as a shield. The glaze sealing layer covers the surface of the stone. Contaminants and wear particles occur on the surface of the glaze, which protects the stone surface.Therefore, the sealing glaze can become the "tempered film" on the surface of the stone.
Whether it is stone care engineering or daily cleaning and maintenance of stone, it is of great significance to determine the wear resistance of the stone surface. What kind of place, how high abrasion resistance is required, what process should be used, and a reasonable choice, not only avoids waste, but also solves the problem.
