Chinese Present situation and development of stone conservation industry

         Stone is a kind of ancient building materials, with its external charm and inherent simplicity, has long been used by the past development of structural materials to the main building materials; with the continuous growth of China's economy, the speed of the development of the real estate industry is accelerating, high-grade hotels, hotels and office buildings are being put into use, stone natural, solid and durable, rich natural charm and primitive beauty, bring people the spice of life and natural feeling, with the progress of stone material processing technology, widely used in the field of architectural decoration, marble, granite, sandstone, tiles, ceramic stone, artificial stone, terrazzo, and decorative stone more of the design, selected as metope, ground and landscape. A large number of stone materials used to promote the formation of the stone conservation industry and its market.

1 development of stone industry

1.1 Four Chinese stone crown

         As same as cement, glass,  Chinese stone in the world famous, "four" crown worthy.

         Our country is a big country of stone resources. China's stone is rich in resources, widely distributed, has proven the varieties of stone has more than 2000, and is still in development, from the Changbai Mountain to five fingers mountains stone resources. The proved reserves are more than 3 thousand mines, tens of thousands or even hundreds of millions of cubic meters, hundreds of years of mining resources are not exhausted.

         Our country is a big country of stone production. According to statistics, China's 2000 stone production reached 15 million tons, but also does not include the building of a large number of Rural stone, in 2001 the total output value of the country's stone production reached about 100000000000 yuan.

          China is a big country of stone consumption. 2000 domestic construction and decoration of the total amount of 60 million square meters of the total amount of square meters, rose to 100 million square meters in 2001.

Our country is a big country of export, the export volume of stone is the world's first.

1.2 the use of stone

          Stone is a kind of ancient building materials, with its external charm and inherent simplicity, has long been used by the past development of structural materials to the main building materials; with the continuous growth of China's economy, the speed of the development of the real estate industry is accelerating, high-grade hotels, hotels and office buildings are being put into use, stone natural, solid and durable, rich natural charm and primitive beauty, bring people the spice of life and natural feeling, with the progress of stone material processing technology, widely used in the field of architectural decoration, marble, granite, sandstone, tiles, ceramic stone, artificial stone, terrazzo, and decorative stone more of the design, selected as metope, ground and landscape. A large number of stone materials used to promote the formation of the stone conservation industry and its market.

1.3 stone care industry development

(1) classification of the main business of stone care

           Stone care's main business segments for stone conservation, stone disease management, stone daily cleaning nursing three elements, the classification is based on the reference medicine "prevention", "treatment", "health", three concept and classification. These three concepts can be used together in stone mining, processing, paving, various stages of daily use.

 (2) the importance of stone care

           Stone care industry is the stone industry, stone industry, the development of stone industry, the use of a large number of stone is a decisive factor in the development of stone care industry, stone care industry is the development of stone industry to a certain degree of inevitable product. As in recent years stone widely used and the rise of, an essential industry, stone care as an emerging industry is increasingly being all aspects of attention, there is much room for improvement in terms of technology and market demand.

2 stone conservation industry problems and advantages

2.1 stone conservation of the current problem analysis

          Stone care relates to organic chemistry, inorganic chemistry, petrology, mechanics, grinding, optical, aesthetics and other disciplines, so stone care industry in addition can be understood as mainly decorative stone in the derivatives industry, from some kind of meaning said stone care industry is also a across the stone processing industry, decoration industry, property, cleaning industry, real estate industry cross and marginal industry.

          Involved in the level of the stone conservation industry practitioners professional quality requirements are very high.

         Domestic stone care industry started late, but rapid development. Huge cake and attracts many eyes, from property management, cleaning cleaning, stone care professional company to swim soldiers scattered died, by stone suppliers, decoration company professionals to buy a second-hand machine, lift keg to play non professionals, entrants jagged flock, in an endless stream. But there are few practitioners who have been trained by formal systems, which greatly restrict the healthy development of the stone care industry and the credibility of the market. In order to better implement the "Building Decoration Engineering stone application technical procedures", the development of conservation, we first analyze the current problems of conservation:

          (1) limit the professional knowledge: as just emerging stone maintenance industry, the majority of owners do not have or have very little knowledge of professional maintenance, many owners in the maintenance still to "wax"; of renovation, ground leveling, door knowledge understood, on the stone, which is a porous material properties or nothing; from the installation to the daily maintenance for decorative stone brought many should not have disease, thus greatly restricted the owner's supervision of construction enterprises, which encourage the whims of the construction enterprise construction mentality. The majority of owners still do not know Stone in need of care, do not care, do not pay attention to maintenance or maintenance failure, resulting in decorative stone is horrible and still use the scene can be seen everywhere; remove the changing scene is not uncommon, not only a waste of resources, an increase of more renovation costs. Even affect the normal operation.

          (2) no chapter: stone industry as an emerging industry, the edge of the stone industry, as other domestic industries, Chinese stone industry took just twenty years to complete the development of hundreds of years abroad; stone industry affiliated industry as the stone industry, before the industry regulations, the relevant standard is not perfect, the guiding role of authoritative enough, no more to develop relevant policies and standards to follow; that construction quality supervision, acceptance and no basis; renovation, nursing completion when light not bright, even light not only has naturally become the acceptance criteria of the majority of the owners how to identify protective materials; the authenticity of the daily maintenance requirements and standards but not on. Often do not maintain the effectiveness of the stone can not be found everywhere.

           (3) low calibration: This is a problem currently widespread in the customers, the majority of owners is limited to the lack of knowledge of maintenance, blindly pursuit of lower costs, bidding price driven, to the qualitative; ignore regardless of the construction cost. As everyone knows, quality, advanced equipment, supplies and construction personnel quality, material quality and operation plays a decisive role in the renovation or maintenance, directly affect the construction quality, the effect and the service life of stone; some practitioners in order to win the bid at the expense of quality: in order to control the cost or profit regardless of quality, industry team participation, more to the stone lesions, corrugated, black seam, false light, improper protection etc. therefore left foreshadowing, ripple, will not be able to make up, the protective effect of poor formation of lesions and so on, not only greatly affects the original design, decorative effect, but also bring the risk to the stone it will be great.

          (4) practitioners uneven: since there is no industry to establish a compulsory education system, the quality of practitioners generally low. The majority of migrant workers without system education, senior management, scientific and technological personnel. The majority of practitioners in no after formal business training, knowledge of professional knowledge of stone conservation understood, simply by virtue of experience or a business licence, the construction of Bibi is; because they do not have the professional knowledge and the emergence of a variety of disputes emerge in an endless stream; on the other hand, in order to obtain the maximum profit mentality breeds construction of randomness, which will not be able to guarantee the quality of high standards. Management, with the lack of domestic labor, staff wages gradually improve, some enterprises in order to reduce the cost, cheap workers, inferior materials used, to employees and to a laissez faire attitude towards management undoubtedly in a large extent become restricting enterprise development is the biggest problem. At the same time, it also has a negative impact on the credibility of the stone industry.

2.2 stone care industry's current advantage

           Stone care industry after years of development, especially in recent years to forge ahead of the enterprise to enter quickly, the performance achieved is impressive: equipment by the imitation of the original, changing to speed up the process of localization for their professional intellectual property rights give great support, stable quality, excellent performance good;

           Domestic maintenance materials for continuous optimization, all kinds of stone protective agent, cleaning agent, crystal hardening agent, maintenance agent, adhesive, reinforcing agent, antique etching agent, abrasive and grinding materials such as environmental protection, high efficiency; nursing technology innovation, technical repair defects are even better than foreign; continuously enhance industry awareness of the main maintenance - in short, requirements people of the stone decorative effect is more and more high, some of the original concept of joint can tolerate cutting uneven, now can not tolerate; only local formation, must now be to the overall level of finish grinding; originally wanted to replace the old decorative stone, now refurbished stone, which was the largest use of stone resources originally just a plane; grinding and polishing, now to do antique surface and non slip surface treatment, exterior wall renovation of the facade was difficult to be non smooth, now requires more particle injection New and so on, have provided us with a favorable signal.
