Chemical weathered yellowstone granite was interpreted by the manufacturer. The chemical weathering of the yellow rust granite means that the yellow rust granite undergoes chemical and weathering changes as the physical weathering produces new substances that undermine the physicochemical properties and external aesthetics of the yellow rust stone granite. Yellow rust stone granite as a natural granite Huangshi, in the external environment affected by the weather will produce chemical weathering, then we talk about chemical windproof fossil yellow granite: yellow rust chemical weathering mainly water-soluble effect, oxidation reaction And karst reaction of three types.
First, yellow rust stone granite water-soluble chemical weathering.
Citrine granite mineral immersed in water, at a certain temperature, chemical changes occur. This process is also known as granulation of Huangshi granite. Specifically, when feldspar is hydrolyzed in the rock, H + in the water displaces the alkali metal ions in the feldspar and H1- enters the lattice of the yellow rust granite, creating a new clay mineral. Second, yellow rust stone granite oxidation chemical weathering.
There are yellow rust stone granite and metal mineral oxidation, yellow rust stone granite discoloration, Songhua, cracks and so on. In the yellow rust stone granite is the most common and most likely oxidation reaction is pyrite in iron ore, pyrite oxidation most obvious. Many yellow rust-proof stone granite installed, the oxidation reaction occurs, the yellow rust, flooding, flow marks, after a long time these iron-containing local pit, crack density will make the intensity of decline. Some relatively stable Huangshi granite, in the production of fire board due to the oxidation of iron oxide at high temperature will be gradually oxidized in the later period, so that the fire board to a certain extent will reduce the use of yellow stone granite strength.
Third, yellow rust stone granite karst chemical weathering.
Usually yellow rust stone granite, granite, limestone, marble and so on. Under the action of carbon dioxide-containing water, calcium carbonate gradually dissolves calcium ions and carbonates. Over time, the temperature and pressure, especially in recent years, a large number of acid catalysts in the urban form of carbon dioxide geological process, the process is usually very long. However, in recent years, the appearance of the yellow rust stone granite rock decoration shows yellowish rust granite flow hairy white, cracks and degradation. Some buildings have found this phenomenon to varying degrees. In addition, gypsum, magnesium, potassium and salts dissolve and separate at the end of the acid rain due to the increase of sulfur dioxide in the atmosphere, which is a kind of damage to the morphology of the yellow rust granite.
These three types of Yellowstone granite are susceptible to chemical weathering. Only by understanding these can we better protect Huangshi granite, prevent yellow rust chemical weathering and prevent damage to Huangshi granite. Be sure to regularly do the conservation of yellow rust stone granite to prevent yellow rust stone granite chemical weathering.
