Stone washing agent: During the production or use of stone, some rust spots will sometimes occur, which seriously affects the beauty of the stone and is fatal to the decoration of the stone. How did the rust spots on the rocks form? How should the rust spots produced by the stone be treated?

The oxidation reaction of iron in the stone is the main reason for the formation of rust spots. The iron in the stone reacts with water and oxygen to form rust spots. Generally speaking, we divide it into two categories according to the degree of reaction to rust spots:

Deep rust spots. Many stone products, especially granite, contain a certain amount of iron. When these iron components are in full contact with oxygen, an oxidation reaction occurs to form iron oxide, which is what we call rust spots. In addition, the alkali in the cement reacts with the iron in the stone under the action of water to form rust spots.

Surface rust spots. During the mining, processing, transportation and installation of stone, a small amount of iron residues will be left after the surface is in contact with iron objects. These residues will oxidize and react with moisture and oxygen in the air to form rust spots.

Many people choose stone as a decorative material because of the durability of the stone and the unique beauty of the stone. After the stone has rust spots, it will not only affect the service life of the stone, but also affect the aesthetics of the stone, so once the stone rust occurs, it must be dealt with as soon as possible.

Through the research and development team, Shi Jiewang proposed the idea of ​​replacing hydrochloric acid and sulfuric acid with all-solid salts in the field of mineral purification, whitening and iron reduction. and make it a miracle. After several years of continuous research and development, we have successfully developed Shijiewang 1, Shijiewang 2 and Shijiewang 3 products! Among them, Shijiewang No. 1 is mainly customized for all quarries to remove yellow skin, and Shijiewang No. 2 product is customized for the viscous kaolin. The product of Shijiewang No. 3 is based on the theme of degrading the toxic substance mercury (mercury). It is an exclusive product for cleaning oil and gas pipelines of CNPC. We develop and produce scientific export-oriented new products, with a good reputation, and sincerely look forward to your visit and cooperation!
