Stone market industry situationTime of issue : 2018- 05-09
China's stone industry chain consists of mining, mining, and large-scale processing. From raw materials to large plates, they can be collectively referred to as large-scale distribution, followed by special-shaped product processing, specification plate processing, and external procurement. Then, the engineering stone distribution link, this section is collectively referred to as engineering stone design and processing, followed by stone installation and stone care, and finally other related.
In the past two or three decades, the international stone industry has developed rapidly. Since 1990, the global stone production volume and trade volume have increased by 7.3% and 9.2% respectively, which is higher than other industries. The development of the whole stone industry is obviously faster than the development of the global economy.
Before the founding of New China, China did not have a stone industry. After the founding of New China, China's stone industry began to take off.
The number of stone products produced in China is increasing year by year. In 2007, driven by the steady and rapid growth of the national economy and the rapid development of related industries, the demand for stone market has increased steadily. In 2007, China exported 3.472 billion US dollars of stone, 27.61 million tons, which increased by 19.45% and 86.30% respectively compared with 2006; imported stone 1.259 billion US dollars, 7.23 million tons, which also increased by 19.70% and 21.11% respectively compared with 2006.
From January to August 2008, China's above-scale stone mining industry for building decoration achieved a total industrial output value of 17,741,979,000 yuan, an increase of 51.74% over the same period of the previous year; the accumulated product sales revenue reached 16,725,289,000 yuan, an increase of 53.70% over the same period of the previous year; The accumulated total profit was 1,012,762,000 yuan, an increase of 57.80% over the same period of the previous year. From January to August 2008, China's above-scale construction stone processing industry realized a total industrial output value of 74,116,464,000 yuan, an increase of 34.45% over the same period of the previous year; realized cumulative product sales revenue of 69,611,911,000 yuan, an increase of 34.80% over the same period of the previous year; The accumulated total profit was 4,781,862,000 yuan, an increase of 28.67% over the same period of the previous year.
The production of Chinese stone is mainly distributed in three major stone producing provinces of Fujian, Guangdong and Shandong. Among them, Fujian and Shandong (Wulian County) are the major raw materials and processing provinces, while Guangdong is mainly engaged in the processing of imported stone. The above three provinces account for China. 85% of the production of stone production, mainly marble and granite products.
The internal consumption of Chinese stone is mainly divided into three parts, namely the interior and exterior decorative panels of the building, which is the largest part of the stone; the second is the building stone, the garden, the engineering stone; the stone carving, the stone art , tombstone products, etc. The use of architectural decoration stone is the most.
The prosperity of China's stone market and the increase in demand for stone have made international stone merchants invest in China. Domestic stone enterprises have also integrated resources and actively participated in the competition in the domestic stone market. The Chinese stone market is moving towards the international stone market center. China's stone market has become an indispensable force in the international stone market. In the near future, the world stone production and trade center will be transferred from Europe to Asia in China.
Due to the market demand, the development of China's stone industry is growing at a double-digit rate every year. Domestic stone consumption demand is still strong in the next few years, and the development speed will remain at double digits. After 2010, the development speed of Chinese stone will slow down, but the annual growth rate of stone production will remain at around 10% to 15%.
Along with the continuous improvement of people's living standards, stone has already entered the ordinary people's home. Widely used in countertops for floor coverings, cabinets and furniture. Under the guidance of the central government's policy of expanding domestic demand and improving the income of urban and rural households, China's per capita stone consumption is expected to increase significantly, becoming a new profit growth point for the industry. The sharp increase in demand for stone will drive the stone industry into the era of stone brand consumption.
Due to the long-term use of stone and its natural weathering, it is easy to cause the natural color and brightness to disap
Daily maintenance of stoneTime of issue : 2018- 05-09
Whether it is new stone or refurbished stone, with the normal use and time, the wear of the stone will become more and more serious and its gloss will be lower and lower.
Stones must be maintained in a timely manner through timely maintenance. If the gloss reduction exceeds the maintenance recovery capacity, the recovery level cannot be achieved.
The correct maintenance method is to adopt the maintenance process in time before the decline of the gloss of the stone does not exceed the recovery ability of the maintenance measures. After the maintenance is completed, the gloss recovery can basically reach the original level, so that the stone remains durable for a long time, which is ideal. status of use.
Due to its natural formation characteristics and the accompanying of various forms of wood, the stone determines that it will cause lesions and weathering damage in its environment, which is caused by its internal cause. On the other hand, the deterioration of the use environment such as acid rain, pollution, moisture, etc. is also the main cause of various problems and lesions in the stone. The consequences of these problems and lesions are serious. From the natural weathering damage of ancient stone artifacts to the various natural damages and lesions of today's architectural stone, the damage caused is enormous. Then, how to effectively prevent this and maximize the avoidance and control of these damages and lesions become more and more important. Waxing has been widely used as a way to protect stone. It is mostly used on the paved stone floor. However, its protective effect on stone is limited, the weather resistance is poor, the antifouling effect is not ideal, and dust is easily attached. Nowadays, people also find that waxing also causes some harm to the stone, because it is applied as an airtight cover protection material on the surface of the stone. After the pores of the stone are closed, the moisture inside and behind the surface is not released. In the interior of the stone, the stone has been damaged for a long time. There is also a liquid wax water that is usually applied to the inner wall surface. This is a film material, and its main disadvantage is that it affects the natural texture of the stone. The emergence of osmotic protection products is a major advancement in the development and research of stone protection products, but the application time in our country is not very long. This kind of product is mostly solvent or water medium, bringing some effective waterproof materials to the inside of the stone. Form a deep protective barrier that shuts off water and some liquid contamination. This kind of permeable protective product not only changes the natural texture of the stone, but also maintains the permeability of the stone. Its performance is superior and scientific and reasonable. However, due to the difference in materials, some products will have different effects on waterproof, antifouling and oil repellent effects, but most products work better.
For the selection and use of stone protection products, in addition to understanding the product performance, we must also pay attention to the following points:
(1) Compatibility. Choose a product that has no effect on the color of the stone. If it is wet-laid construction, it should be checked whether it will affect the adhesion between stone and cement when it is treated on the back of stone.
(2) Under the condition of wet sticking construction, it is necessary to do a good job of treating the back and side of the stone, then focusing on selecting a protective agent with good waterproof effect.
(3) In addition to the waterproof treatment of the back surface, the front side of the stone should be properly protected according to the use environment. Some special places, like hospitals, must choose products with good anti-fouling performance. For hotels, they must choose anti-pollution and anti-oil protective products.
(4) The significance of dry-hanging stone for the protection of the back side is not significant. For the front side, the corresponding protective products can be selected according to the use environment and the characteristics of the stone.
(5) For stones that are prone to lesions, like some grayish white granite and marble, often rust or spit in wet conditions. It is important to do waterproof treatment, and the protective agent should have excellent waterproof effect.
(6) For granites with high water absorption and high water absorption, use them in public environments. Be sure to choose products that are waterproof, anti-fouling and anti-spray, so that they can be easily cleaned once they are contaminated.
