What are the reasons for the weathering of Landscape Stone?

Whether it is a natural Landscape Stone product or a processed Landscape Stone product, weathering will inevitably occur during use, especially the Landscape Stone placed outdoors, so what is the reason for the weathering of the Landscape Stone? The following is a simple editor to share with you, hoping to help you.

1. The role of lower plants: under the conditions of water and suitable temperature, the sporangia of organic matter such as moss and mold are attached to the surface of the Landscape Stone, and begin to develop and grow, so that various organic growths are formed on the surface of the Landscape Stone. Stains, in order to survive, these organic substances fight against carbon dioxide, sulfur dioxide, nitrogen dioxide and other substances in the air, changing the surface texture of the Landscape Stone. In addition, after these plants die, they form organic acids with water to accelerate the aging of Landscape Stone, causing erosion of Landscape Stone.
2. Ultraviolet radiation: Landscape Stone itself has many capillary pores, and the smaller the capillary, the more obvious the capillary phenomenon. Therefore, after the Landscape Stone absorbs water, under the radiation of sunlight (ultraviolet rays), the evaporation rate of water in the capillary pores of the Landscape Stone will be accelerated, and the erosion rate of the substances in the water that will erode the Landscape Stone will also increase. Cause the aging of Landscape Stone.
3. Cracking effect: Gluing is one of the installation methods of Landscape Stone. The viscose remaining on the surface of Landscape Stone causes relaxation of the cemented minerals bonded to Landscape Stone due to aging, which makes the interior of Landscape Stone loose and the surface is easy to Peeling off, thus accelerating the aging of Landscape Stone.
4. The role of thermal energy: Landscape Stone expand due to heat during the day, and contract due to cold at night, resulting in thermal expansion and contraction, and Landscape Stone contain many different minerals with different expansion coefficients, resulting in granular denudation or lumps. disintegration.
5. Freezing and thawing of water: The freezing and thawing of water can also weather the Landscape Stone: when the temperature drops below 00C, the water freezes, causing the Landscape Stone to freeze and expand rapidly after absorbing water, causing the Landscape Stone to disintegrate and shatter.
Landscape Stone have been used in gardens for a long time. It is an ancient natural building material. Because of its good decoration and high strength, it has been widely used. Due to the vigorous development of modern processing industry, Landscape Stone has been fully used in residential areas, parks, scenic spots and other places.
