source of Marble Sculpting

Nowadays, in modern cities, urban Marble Sculpting are very common and have many advantages, which has led to more urban stone sculpture using stone sculpture as raw materials, which are resistant to weak corrosive media such as air, steam, and water. Marble sculpture has a history of only one hundred years since its birth in the last century. Urban marble sculpture is an item used for decoration in the process of urban governance planning to meet people's pursuit of beautiful environmental space.

Rust is visible before or during the manufacture of stone carving products or equipment, indicating that the appearance is seriously polluted. Before the equipment is put into use, it must be derusted. Fully finished surfaces should be checked by iron test and/or water test.
Organic substances such as oil, grease or even fingerprints will be the source of localized corrosion. Since these substances act as a barrier, they interfere with chemical and electrochemical cleaning and must be thoroughly cleaned.
Production often takes place in dusty locations. The air often contains a lot of dust, which is constantly falling on the surface of the equipment. They can be removed with water or alkaline solutions. However, the adhered dust needs to be cleaned with high-pressure water or steam.
When the tape and maintenance paper are removed, some adhesive remains on the surface of the stone carving. If the adhesive is not hard, it can be removed with organic flux. However, when exposed to light or air, the adhesive hardens, forming a corrosion source for crevice corrosion. It is then mechanically polished with fine abrasives.
Welding defects such as undercut, incomplete penetration, pores, cracks, etc. not only reduce the firmness of the joint, but also become the corrosion source of crevice corrosion. To improve this result, they will also contain solid particles when performing cleaning operations. These defects can be repaired by re-welding or re-welding after grinding.
