During this period, many friends have inquired about similar issues, such as the rust that has seeped up from the bottom of Shandong Huangjinma. During use, it is not only common, but also has a high cleaning coefficient, with rust spots appearing on the surface. Do you know what caused this problem?

Deep rust spots: Due to the full contact of iron, water, and oxygen inside the rust stone, oxidation occurs, resulting in the formation of rust spots. During installation, the alkali in cement reacts with the iron in Shandong golden hemp under the action of water, which can also form rust spots.

Surface rust spots: During mining, processing, transportation, and installation, when the surface comes into contact with iron objects, a small amount of iron residue is left behind. These iron residues react with water and oxygen in the air to oxidize, leading to the formation of rust spots.

Contact with high iron content substances: The contact between Shandong golden hemp and high iron content substances (stainless steel, iron components) can easily cause reactions, leading to rust spots on the surface of Shandong golden hemp.

Rainstorm under extreme weather conditions: long-term rainstorm weather will also make the surface of Shandong Huangjinma permeate with water, and trace metal elements (iron elements) in the water will dissolve in the water, thus forming rust spots.

Improper surface cleaning: During cleaning or maintenance, improper use of chemicals or methods may also lead to rust spots on the surface of Shandong golden hemp.

Regardless of which method causes rust to appear, it is necessary to do a good job in protecting Shandong golden hemp, and use high-quality penetrating protective agents to provide a high standard of protection to Shandong golden hemp to avoid similar problems in the future.

It is recommended to regularly inspect and maintain Shandong golden hemp. If rust spots appear, corresponding methods should be taken in a timely manner for treatment.
