How to prevent granite marble from corroding

If we do not maintain granite marble, the corrosiveness of granite marble in daily life will increase greatly. So how to prevent its corrosion?

1. Industrial gases such as nitrogen oxides, hydrocarbons, sulfur oxides, carbon oxides and acidic particles (such as surge in content) will form acid rain when dissolved in water, corroding stone and affecting service life.

2. Industrial emissions include “slag” and “waste” of acid or alkali, which form corrosion and corrode stone.

3. During the construction process, corrosive chemicals may be accidentally spilled on the stone.

4. Once the stone is cleaned or repaired, improper use of curing agents will lead to the formation of corroded stone.

Natural chemical corrosion is caused by the following factors

1. HNO3 acid rain caused by natural N2, O2, H2O emissions occurs, causing roadside stones to rust.

2. Nitrate bacteria in natural air will corrode HN3, O2, HNO3 acids under certain conditions.
