Whether it is natural stone or artificial stone, it has gradually become a type of building stone product widely used in the modern construction industry, and whether it is natural stone product or artificial stone product, it will inevitably appear weathering during use; then, natural Why does the phenomenon of wind bloom appear in marble stone? Below, let's take a look with the editor of FABULOUS Group.
1. Ultraviolet radiation:
The stone itself has many capillary holes, and the smaller the capillary, the more obvious the capillary phenomenon. Therefore, after the stone absorbs water, under the radiation of sunlight (ultraviolet rays), the evaporation rate of water in the pores of the stone will increase, and the erosion rate of the stone with the substances that erodes the stone will also increase. Cause the aging of the stone.
2. The role of lower plants:
Under the conditions of water and suitable temperature, the sporangia of organic matter such as moss and mold attach to the surface of the stone, and begin to develop and grow, causing various organic stains on the surface of the stone. These organic matter will interact with the air in order to survive. The carbon dioxide, sulfur dioxide, nitrogen dioxide and other substances in the material compete to change the surface texture of the stone. In addition, these plants form organic acids with water after death, which accelerates the aging of the stone and causes the stone to be eroded.
3. The freezing and thawing effect of water:
The freezing and thawing effect of water can also weather the stone: the temperature drops below zero and the water freezes, causing the stone to expand rapidly after absorbing water, causing the stone to disintegrate and break.
4. The role of heat:
Stone expands due to heat during the day, and shrinks when exposed to cold at night, resulting in thermal expansion and contraction. The stone contains many different minerals with different expansion coefficients, resulting in granular erosion or blocky disintegration.
5. Sticking effect:
Adhesive is one of the stone installation methods. The glue remaining on the stone surface will relax the cemented minerals of the bonded stone due to the aging effect, so that the inside of the stone is loosened and the surface is easy to peel off, thereby accelerating the aging of the stone.
