Due to the advancement of cutting and grinding stone processing technology, the surface of the commercially available natural stone is very dense, and the gloss after polishing can almost achieve the mirror effect. Therefore, consumers often think that stone is as hard and airtight as bright metal or glass. In fact, natural stone is a porous material whose surface is easily damaged by inhalation of external pollution. In other words, natural stone, like natural wood, is a respirable material whose microscopic structure has porous characteristics (sometimes It is easy to observe from the appearance, and therefore it is easy to absorb the contamination that is invaded by water dissolution or oily dissolution. In addition, although the stone is hard, but the surface is still inevitable after a period of use, it needs to be re-polished. Therefore, why the stone needs to be related to pollution maintenance and regular maintenance after installation. The reason is here. The following is a description of the reasons why the stone should be maintained and the precautions for each material of the stone. Stone is a natural material and is a variable substance. Stone is a naturally occurring architectural finish, and its composition is full of variations. The change will vary greatly depending on the chemical composition at the time of formation or the ambient temperature and geological pressure conditions during the formation. Therefore, we can say that stone is a kind of material with variable character, and its characteristics are extremely important for color and pattern. From the splendid Indian emerald red to the rustic and hard sandstone, it is covered in the category of stone building materials, its water absorption rate, thermal expansion rate, chromophore stability, acid corrosion resistance, alkali corrosion resistance and surface hardness. There are great differences. Therefore, the maintenance of stone should be different for different stone materials, should be taken seriously, and systematically researched and summarized to establish stone maintenance guidelines based on stone properties. Stones are installed in different environmental conditions and face different conditions The thermal stress after sun exposure, the internal stress caused by the icing expansion after the snow and rain invaded the stone, the acid rain erosion, the salt water intrusion in the monsoon zone and the soot accumulated in the exhaust gas will cause the stone to age or foul. Therefore, the stone needs regular maintenance to keep the stone fresh. Stone maintenance should pay attention to matters At present, there is no set of professional specifications for stone maintenance and cleaning in China. The professional quality of stone maintenance and cleaning practitioners varies greatly. The company scales from professional manufacturers with complete personnel expertise and complete education and training to family-based operation. The construction team has it. When consumers face the choice of stone maintenance companies, they often feel at a loss and do not know how to achieve a balance between economics and professionalism. Here, the items to be evaluated before the stone maintenance are explained one by one, and the consumers are provided as a reference.
