Analysis of the causes of cracks in Zhangqiu black stone

What is the reason for the cracks in the Zhangqiu black stone, how do we deal with the cracks in the Zhangqiu black stone, and what are the reasons for the cracks? There are many reasons for the cracks in the Zhangqiu black stone:

One is man-made sabotage;

2 is biological influence, such as weeds, moss, and vegetation attached to the surface of Zhangqiu black stone, which will increase the storage time of water on the surface of Zhangqiu black stone, making the action time of water and Zhangqiu black stone longer. The development of micro-cracks in the black stone of the hills leads to the continuous expansion of the cracks. In addition, the plant roots will secrete acidic substances after the decay and deterioration, which will also accelerate the dissolution of the black stone of Zhangqiu;

3. Freeze-thaw damage. The moisture in the pores of Zhangqiu black stone will freeze when the temperature is very low, resulting in thermal contraction and cold expansion, which will also cause Zhangqiu black stone to crack.

So how to deal with the macular phenomenon of Zhangqiu black stone, how does the macular phenomenon of Zhangqiu black stone happen, how do we remove the macular, let's explain to us about the macular phenomenon of Zhangqiu black stone deal with.

often putZhangqiu HeiThe macular appearing on the stone is mistaken for rust. The rust contains iron, which can be removed with a rust remover. There are generally two causes of macular, which are easy to be mixed with rust. One is when wet sticking and filling Zhangqiu black stone, cement The organic additives penetrate into the surface through the capillary pores on the bottom surface, and the double bonds of the organic components are broken under the condition of water and oxygen, and the color turns yellow.

This kind of situation is more common in wet paste and filling type Zhangqiu black stone. There is also a situation in beige marble, because the alkali spot spreads to the surface and absorbs crystalline water to form a gel layer, changing the light refraction makes the alkali spot The color becomes darker, it seems to be "more yellow", in fact, the gel layer containing crystal water is at work, so the macular caused by these causes cannot be simply treated with a rust remover.
