The Yashi white stone we are talking about here refers to natural stone, not artificial stone. Natural stone cannot be regenerated. No two stones are the same in the world. Therefore, people should take special care of many precious stones to extend the service life of the stone as much as possible to prevent the external environment and internal diseases of the stone. Stone caused damage, so, today, we will talk with the editor of FABULOUS Group about how to maintain natural white marble.
The external causes of Yashi White Stone include climate, weather, and human production and living factors, such as temperature changes, rain, wind and snow, frost, sea water erosion, and humidity; colleagues also include objects in contact with stone and metal in decoration materials , Adhesives, other supports, supporting objects; and the influence of ambient air composition on stone is the most important aspect in recent years. In particular, the acid gas content in big cities has risen sharply. For example, SO2, CO2, NOx and suspended particulate matter (TSP) are all factors that cause stone corrosion. my country is a country with serious sulfide pollution, and the acid rain formed is also corrosive to stone. Important aspect.
The research on the corrosion mechanism of Yashi white stone is actually to study the damage caused to the stone between the internal factors and the complex environment of the stone. The internal factors of stone include its chemical composition, mineral composition, and particle structure. For example, marble is a rock dominated by calcium carbonate and magnesium carbonate. Due to its composition, it is much easier to be destroyed by the natural environment in nature than granite; while sandstone is more uniform and more pores, causing a large area of water absorption. , More attention should be paid to the intrusion of dirt. Granite is mainly composed of silicate, which is relatively stable and denser than other stones, and is more difficult to be corroded.
