Impact stone life factors

People believe that the stone is a long-term high-grade decorative materials.In fact, in the natural environment, dust, exhaust, acid rain, freezing and other pollutants caused architectural stone easily fade, pollution or even destroy,greatly reducing the the stone decorative effect and service life, at the same time, due to the mistakes of the construction method, can also cause the failure of the stone decorative effect in the short term, which had re-decoration of buildings, and caused a lot of waste of human and material resources.

The ressons of make stone be diseaser and shorten the life,summed up in professional terms:

First, the internal reasons: both the structure and chemical composition of the stone caused the change;

External reasons: the impact of both mining and processing methods,installation of construction technology, the use of the environment, and other factors.The main reason affecting the life of stone and stone disease Reasons from the stone  Structure constructed of stone: natural stone, there are micro-cracks and pores, fine dust and dirt in the air will absorb considerable period of time, due to capillary action and slowly infiltrated the stone , which greatly reduces the performance and use of decorative stone life. The porosity smaller, the stronger the capillary action and surface adsorption.

Relatively complex chemical composition: some of the ingredients in the stone easily with the external environment play a role, so the stone to produce the phenomenon of erosion or variation. The stone generally different degrees of iron-containing ingredients, erosion by moisture will produce yellow rust. The higher the iron content in the stone, the rust colors easy to occur.

Further, the main component of the majority of natural marble, of carbonate,such as calcium carbonate and magnesium carbonate, as well as a small amount of alkali oxide. Calcium carbonate and magnesium carbonate is a relatively stable compound, but the unstable chemical nature of some of thealkaline oxides, and easily with the air in the acidic oxide in a wet environment, such as carbon dioxide, sulfur dioxide, sulfur trioxide, dioxide nitrogen, etc. chemical reaction occurs to change the physical structure of the marble interior. The similar chemical destruction will occur on the other stone,light stone surface will lose their luster, even colors Fading, there scar;serious cases will decline in natural stone hardness, surface weathering peeling.
