The status quo of
China's stone care With the continuous development and improvement of the stone care industry, this emerging industry is full of vitality and development opportunities. It not only represents the improvement and progress of the after-sales service of China's stone industry, but also represents the improvement of the level of stone care services in China's clean and property industry. The rapid development of the stone care industry has led to a surge in the number of employees. The entry threshold of the industry is low, the level of technology is uneven, and the industry management is not standardized. It also causes the industry to encounter bottlenecks in development while developing rapidly. In order to make breakthroughs in this field, more industry practitioners began to change their business model and develop in the direction of specialization and deepening. This development strategy will definitely bring the technology of stone care industry to a new level. Compared with foreign countries, China's stone care industry started late, but thanks to the huge amount of stone used in China and frequent exchanges with domestic and foreign counterparts, China's stone care industry is developing very fast, in renovation machinery and renovation. And daily care has reached international standards. Moreover, with the improvement of industrial support, market segmentation began to appear, brand awareness began to strengthen, and the trend of service specialization was significantly strengthened.
Attention should be paid to the four points of stone care
. With the development of stone conservation engineering practice, the maintenance technology is greatly enriched. However, some new problems have emerged in the recent practice of stone conservation, and some new ideas have been formed, which are summarized as follows. First, not all natural stone needs protection. If it is only waterproof and anti-alkali, some high-hardness and high-density stone in the ten-hanging construction can not be protected. Second, stone protection should be suitable for garden materials, construction of materials, and sometimes the protective agent for some varieties of stone protection is not good. Excluding improper construction and production failure, the most likely reason is that the correct stone chemicals are not used for protection. Even the same type of stone will increase or decrease the concentration of silicone resin due to differences in density and chemical composition. Therefore, in the construction of stone conservation, it must be adapted to the material, and it must be constructed according to the material. Different chemicals and different construction techniques are selected for different stone materials. Third, do not blindly believe in imported stone conservation products, and do not prejudice domestically produced products. Under normal circumstances, the maintenance products of foreign brands are generally considered to be a symbol of high quality. In fact, these prejudices stem from the lack of understanding of stone conservation knowledge. All protective agents, whether imported or domestically produced, are composed of active ingredients plus diluents and auxiliaries. There is no difference between this entry and domestic production. In recent years, the development and application of domestic stone protectant products have developed rapidly, and it has been close to foreign advanced water in the field of silicone monomer manufacturing and resin synthesis. It is equivalent to foreign countries in the compounding process. In the field of construction applications, it is ahead of foreign countries. Fourth, natural stone floor paving does not need to use smooth stone, after the roughing of the rough surface, and then artificial stone conservation. If the floor paving is to choose the smooth surface of the smooth stone, then also find the flat renovation, equal to repeat The polishing process has a high cost. The correct way is to choose the smooth surface of the stone, then buy the matte specification board, and then paving, leveling, refurbishing and curing. This can greatly reduce costs. This method has long been used in engineering practice in foreign countries, and has not yet formed an application in China, mainly because of the disconnection between stone consumers and construction companies, which is inconsistent in concept. The high cost is entirely borne by the consumer.
