What factors lead to Zhangqiu black aging?
Zhangqiu black not only has the effect of beautification, but also has a good decorative effect. However, any stone will age after long-term use. Apart from the normal use time, what other factors cause it to age? Zhangqiu black factory I will share with you the reasons for the aging of Zhangqiu black stone.
1, the role of lower plants:
Under water and appropriate temperature conditions, sporangia of organic matter such as moss and mold attach to the stone surface and begin to develop and grow, causing various organic stains on the stone surface. These organic matter are related to carbon 2 oxide in the air, 2 Sulfur oxide, 2 nitrogen oxide and other substances resist and change the surface texture structure 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 erode.
2, UV irradiation:
The stone itself has many capillary pores. 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 stone pores will accelerate, and the water will erode the stone. The erosion rate of the material on the stone will also increase, resulting in the aging of the stone.
3, sticky cracking effect:
Adhesion is a method of stone installation. The residual adhesive on the stone surface will relax the cemented minerals of the stone due to the aging effect, so that the interior of the stone is relaxed and the surface is easy to peel off, thereby accelerating the aging of the stone.
4, the role of thermal energy:
The stone expands due to heat during the day and shrinks due to cold at night, resulting in thermal expansion and contraction, and the stone contains many different minerals with different expansion coefficients, resulting in granular denudation.
