Inferior cleaning agents are often strong acids, which are likely to cause more serious stone diseases such as surface loss and chalking, water spots and salinity spots, loose dissolution and yellowing. For example, the use of imitation stone paint on the external wall, we have used the waste of sawing stone to make a coating of imitation fire board and wool board: for indoor floors, for example, some of the more severe corrosion, holes, cracks or loose stones, etc. The resin and filler can be used to fill the holes and cracks, and then penetrated and reinforced with the stone reinforcing agent, and then polished.
For some shallow smudges that are difficult to remove by cleaning methods, such as organic stains, salt spots and white hua, water marks and water spots, grinding and sandblasting methods are also effective, but the cost is higher. Our stone reinforcements are often used in the renovation of stone. Some new combinations of abrasives, abrasives and chemical additives can achieve a mirror finish with a refurbishment of more than 90 Gauss. Foreign sandblasting refurbishment methods have become more common, but similar high-quality particle jet machinery products have not yet been seen in the country. Grinding, sandblasting and coating are the most basic retreading techniques. The particle materials are: quartz powder, natural fine sand, corundum powder, calcite powder, glass microbeads, blast furnace slag particles, plastic particles, etc. These particles can be divided into general particles (0.1~0.5m) and fine particles (0.05~ according to the diameter). 0.1mm), depending on the situation. Sandblasting, also known as particle spraying, can restore the original natural appearance of rough and irregular surface stone, such as wool board, fire board and sculpture. Therefore, we do not know the detailed causes of smudges, we advocate small trials first. Therefore, it is recommended that users should first select high-quality products from reliable manufacturers. Secondly, they should protect the departments that are not ready for cleaning before cleaning. After cleaning, the residual chemicals should be removed. In addition, the cleaning of stone cultural relics should be done by relevant experts. Argument. The "diseases" of stone vary widely, for example, there are many types of deliquescent salts that form water spots.
