The importance of regular stone maintenance 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 reach 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. Diamond abrasive is a large-scale industrial production in the past 30 years. Its microhardness is 8000-10000 kg/mm2; the hardness is the highest, and the material is micro-cutting mechanism. Therefore, it is the preferred cutting tool. It has a large-scale increase in production and a reduction in industrial costs, high processing efficiency (more than 5 times normal), good processing effect (can be used for polishing highly demanding materials), and thus its application is becoming more widespread. Diamond grinding tools mainly include metal, resin, ceramic, etc., which are classified according to the type of bonding agent. Metal grinding tools mainly include iron-based, copper-based, and cobalt-based. It determines the processing cost of different types of materials. As a grinding tool, its particle size is used from the thickest (20#), often to the fineness of 400#. It is characterized by long service life, but the cost will be higher. Resin-based grinding tools, due to their relatively low manufacturing costs, have relatively large applications. They are now used for rough grinding to polishing, and are the biggest advantage in fine-grained grinding and polishing. So, how to carry out effective protection of stone? 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. The stone is installed under different environmental conditions, and the conditions faced are different from the thermal expansion after sunshine, the internal stress caused by the icing expansion after the snow and rain invades the stone, the acid rain erosion, the salt water intrusion in the monsoon zone and the carbon accumulated in the exhaust gas. Smoke, etc., will cause aging or fouling of the stone, so the stone needs regular maintenance to keep the stone fresh. Attention should be paid to stone maintenance. 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 staff expertise and complete education and training to family style. Construction teams operating only by experience. 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. Matters to be evaluated before daily maintenance of stone 1. Stone surface treatment methods are different, should choose different maintenance points (rough surface and smooth surface maintenance focus). Generally speaking, architects and designers display the design effect. It is a very common phenomenon that the same building uses different surface materials for the decoration of the building. The visual effect expressed by the stone with different surface treatment methods also has some visual effects. Different, for example, the surface of the polished stone has become more dense, and the chromonic structure contained in the stone also shows that the mountain has a stronger color change than the original surface, which can create a delicate and magnificent effect, therefore, its maintenance The purpose is still to maintain the brightness of the surface of the stone and the brightness of the gloss. The more common maintenance methods focus on curing treatment, waxing treatment, color enhancement treatment, re-polishing treatment, damage compensation, and pollution removal treatment. In contrast, the surface of the roughened stone is expressed in a rough original feeling or as a mosaic contrast of a glossy sheet. The more common maintenance is still based on the regeneration of rough surface, pollution removal, water repellent treatment (should choose a maintenance material that does not form a surface coating and does not increase color) and damage reinforcement, without the need for color enhancement, because there is Some of the curing materials or chemical treatment agents may cause the matte stone to deepen in color. If it is used in the arrangement of thick and thin plates, it may bring the color of the light plate and the rough plate closer and destroy the original design. Similarly, smooth maintenance is not suitable for rough slate. Therefore, consumers should carefully consider and evaluate the maintenance items so as not to pay for the maintenance but not the best results. Second, different stone materials should have different maintenance priorities . Natural stone building materials on the market are roughly classified into marble series and granite series. Although from the point of view of geological formation conditions and chemical composition, this classification method is slightly rough and does not match the true characteristics of stone, but the basic properties considered in the maintenance of stone can still be further in accordance with this classification rule. Consider the preliminary basis for the applicability of the maintenance method. Granite-based granite stone usually has a harder character, and its Mohs hardness is about 6-8 (depending on the type of granite). The simple judgment method is: granite is more common metal (such as key). Hard, therefore, when the surface of the feldspar and quartz is scraped with a general iron, the stone itself will not be scratched. The luster of granite is damaged by pedal wear or external force, and the frequency of re-grinding is lower than that of marble-based marble. The Mohs hardness of marble is about 3-5 degrees. The simple method of judging is that marble is softer than ordinary metal (such as a key). Therefore, when the surface is scraped with a general iron, the stone itself is easily scratched. Therefore, for the characteristics of different stone materials, consumers should evaluate the maintenance methods and maintenance frequency they need to perform. All in all, the most important consideration for stone maintenance should be to understand the weaknesses of the stone from all possible information, and to list the factors that may be harmful to the vulnerability at the installation site, and to seek possible maintenance methods to strengthen the stone. Resistance or reduce the possibility of rapid deterioration, in order to achieve the new effect of stone often. The specific information needs include the chemical composition of the stone (the Stone Industry Development Center and the "Stone Catalogue" issued by the Taiwan Association of Stone and Mineral Products Industry, which details the various materials and origins of the commonly used stone in China), and the surface treatment of stone. The nature of the post, the hardness of the stone, the characteristics of the stone and the state of the method of installation (the stone industry development center and the "stone installation method and related matters" related to the publication of the Taibi City Stone Products Commercial Association, the stone and the surrounding building materials Coordination status, stone characteristics are facing the resistance of the installation environment, the stone characteristics are facing the climatic factors of the construction site, etc. Third, attention should be paid to the influence of regional climatic factors on the stone. The aging effect of the climatic conditions on the stone is very obvious. In the cold zone, the stone If it is not waterproofed before installation, if too much water is inhaled before snowing, it may condense into ice directly inside the stone after the temperature is below freezing point, and then volume expansion phenomenon (volume ratio of ice in equal weight) The water is big.) It causes stress on the interior of the stone and even breaks the stone. In addition, the phenomenon of acid rain and alkali rain absorbed by the stone is a matter that should be evaluated before the stone maintenance project. The consumer should evaluate the company when considering the construction of the maintenance project. Relevant processing ability and professional quality. IV. Avoid environmental factors that are easy to cause stone aging. The surrounding environment of stone installation has many factors affecting the deterioration of stone. For example, the stone installed in the bathroom area is prone to acid etching due to improper cleaning habits. The phenomenon of yellowing. The phenomenon of accelerated wear and tear is prone to occur in frequent areas of public foot pedal wear. In the kitchen or dining area, the stone is easily stained by oil stains and color materials. Relevant environmental factors should be used in the stone maintenance work. Take into account to obtain the best maintenance effect. 5. After the maintenance project to be implemented is integrated, the evaluation work should be carried out before the maintenance project can be started and the schedule planning can be started. After confirming the necessary maintenance items, select Proper maintenance of materials and collection of correct methods of operation to be organized and efficient Stone maintenance work. Sixth, choose the appropriate maintenance engineering company stone is a basic feature of the complex building materials, the relevant maintenance technology points are affected by a wide range. Therefore, the current work in the domestic stone maintenance is still Contracted by professional cleaning company personnel, but consumers face the risk of stone maintenance failure caused by the uneven technical level of domestic companies. It is recommended that consumers should actively establish the basic evaluation ability of stone maintenance: engineering. In order to understand what must be done for maintenance, which company should be selected for construction. 7. Cleaning the surface of the stone should be done with a neutral lotion after the wet installation of the stone, the construction workers often seek to quickly leave the surface or the residual cement around the joint , or cement-containing adhesives are quickly removed, often using acidic detergents such as acetic acid, hydrochloric acid, etc., if the stone of the project has not been cured beforehand or has not been effectively cured, it often causes acidic agents on the stone surface. Residue, causing the cause of stone lesions in the future. Therefore, it is recommended in this general Stone cleaning mode should be used under a neutral lotion.
