Do you know why rust appears on the fire board? We all know that the use of fire plates is very wide. In order to extend the service life of fire plates, we should understand how to remove rust spots. So below, we will introduce the methods for removing rust spots.
The main reason is related to the internal structure of the stone. There are microcracks and capillary pores inside natural stone, and in the natural environment, the surface of the stone will be adsorbed by pollutants such as acid rain, exhaust gas, and dust, resulting in fading, pollution, and pathological states of the stone, greatly reducing its decorative effect and service life. The smaller the capillary pores inside the stone, the stronger the capillary action and the better the surface adsorption effect. And this is related to the chemical composition of the stone itself, which contains many chemical elements. The outside world can react with these chemical elements, causing the stone to corrode or mutate.
When the humidity in the air is high, rust spots will form. However, due to the varying degrees of iron content in stone, the higher the iron content in stone, the easier it is to rust. In addition, most natural marble is composed of small amounts of alkaline oxides and carbonates such as calcium carbonate and magnesium carbonate. Although calcium carbonate and magnesium carbonate are relatively stable compounds, the chemical properties of these alkaline oxides are unstable. They easily interact with acidic oxides such as carbon dioxide, sulfur dioxide, and sulfur trioxide in humid environments, and nitrogen oxides and other chemical reactions can alter the physical structure of marble. Similar chemical damage may also occur on other stones, which can cause the surface of the stone to lose its luster, even resulting in color fading and stains. Rough stones can also reduce the hardness of natural stones, leading to surface weathering and peeling.
As long as we understand these reasons, in order to prevent secondary damage to the fire board, we need to know how to remove rust spots, improve its appearance, and extend its service life.
