The Egyptian stone industry has a long history and brilliant achievements. Nearly 7000 years ago, Faros Lighthouse deeply integrated the "Egyptian architecture" with the "stone concept", leaving a lot of commemoration for the later generations. Architectural art heritage in the form of a mausoleum. The pyramid as an existing world architectural miracle is a vivid example of these masterpieces.
Second, the status quo of the Egyptian stone industry
There are about 2,500 stone enterprises in Egypt, and there are about 100,000 stone workers. Among them, the SHAQ AL-T-HOBAN area in Egypt is the fourth largest stone processing industry cluster in the world. At the same time, Egypt is currently one of the top ten marble blocks in the world. At the same time, Egypt is also one of the world's seven largest exporters of marble plates.
Third, the Egyptian granite product variety
There are more than 10 excellent varieties in Egyptian granite, such as Aswan Red, Tear White, Sergeka, Charmu, Lake Yellow, Lake Red, Charmu, Royal, Weldi and Arabic Jade. Suez Green. These varieties have long been known in the world of stone.
Fourth, Egyptian marble product varieties
Egyptian marble is world-famous and has many excellent varieties, especially the current stone color is yellow (beige), while the main marble varieties in Egypt are mainly beige, plus the characteristics of stone and The quality of the blocks is good, and it is more popular for people. The main marble varieties in Egypt are splendid, dark, gold, beige, steel, beige, bili, Sinai, Alabastel, gold, beige, rose, jade, pearl, sahara, yellow, gold Silk beige, new sago, etc., are all well-known and widely used stone varieties.
Fifth, the production capacity of the Egyptian stone industry
Egyptian stone production and processing capabilities:
Mining capacity: 3.2 million tons / year
Sawing capacity: 18 million m2 / year
Grinding capacity: 12 million m2 / year
Sixth, the current problems of the Egyptian stone industry
Funding problem
The general capital accumulation of Egyptian stone enterprises is not high. This is because the local stone enterprises in Egypt have long been using a single product variety, low product value, generally small scale, and lack of deep processing capability of stone. The original Egyptian stone products are mainly block materials and plates, and the sales volume in Egypt is not high. The foreign countries also rely on low-price competition. It can be said that Egyptian stone is synonymous with low price in the international market, which makes the stone enterprises in Egypt Lost a lot of profit margins. Although the current stone industry is also on the road to finishing and deep processing, there has not been any significant change for the time being.
Technical and supporting issues
Egypt's stone industry in the entire stone industry chain, only relying on the country's excellent stone resources and occupy a prominent position in the production of products, but in other related industries, such as stone machinery, stone tools, abrasives, Stone chemical, stone conservation, stone design, stone decoration and other aspects are very weak. And the most important point is that the supporting infrastructure required for the production of the Egyptian stone industry is also very weak. In the famous Cairo Snake Stone Industrial Zone in Egypt, for example, the tap water pipeline has been built up to date. The supporting facilities are indeed very backward.
Lack of industry organization and marketing platform
The Egyptian stone industry association was also established late. The Egyptian Marble and Granite Association was established only a few years ago, and only this professional stone association was previously used by companies themselves. Moreover, the influence of the Egyptian stone industry association industry is very limited, only a few dozen members, which is too small compared to more than 2,500 stone enterprises in Egypt.
Egypt has not had its own professional stone exhibition so far. All stone enterprises can only participate in the domestic building materials exhibition together with the building materials enterprises (the most active foreign contact in Egypt is also the Egyptian Building Materials Chamber of Commerce), or they can only participate in foreign stone materials. The problem is that this can only be a patent of a large company. For the majority of small and medium-sized stone enterprises, the cost is too high. There is also no professional stone journal or stone magazine in the entire stone industry in Egypt.
Seven, the future strategic goals of the Egyptian stone industry
1. Direct investment in the development of the Egyptian stone industry can be assisted by external forces, through the investment and development of the stone industry, on the one hand can solve the problem of capital, at the same time can introduce advanced foreign management and technology to solve the problems of technology and industry support.
2. Expand the influence of the stone industry association, play the role of the industry in the stone industry, enhance the overall level of the domestic stone industry, and cooperate with and promote the development of the stone industry. Relevant supporting facilities include: establishing a strategic partnership with the Italian Stone Association and cooperating to establish a marble and granite technology center; establishing a “testing laboratoryâ€, ASTM (American Society for Testing Materials) certification for the use of stone products and CE for the European Union. Certification; the establishment of "Quarrying School", on-site training of quarrying technicians, teaching advanced quarrying techniques; conducting "rock and rock formation analysis, on-site assessment of rock formation conditions, giving the best quarrying plan; and so on."
3. Improve the production and management level of stone enterprises in the industry, train the interior of stone enterprises, and improve the skill level of technicians and mechanics in production and processing. At the same time, domestic and foreign experts are invited to conduct production and management guidance for processing enterprises, and provide corresponding technical and management support.
4. Build a marketing and promotion platform for the stone industry, set up a technology and then a commercial information center to improve the soft power of the stone industry.
5. Launched the “Stone Paving School†to teach the advanced stone paving technology and stone conservation knowledge of the ground paving personnel to develop the domestic stone consumption market.
2. The glass slide is at the bottom, which is the carrier for the material you want to observe, that is, you want to put something on it.
3. The cover glass is smaller than the slide glass. The glass slide is mainly used to hold the observation objects. The cover glass is covered on the slide glass and used for fixing.
4. The glass slide is a thicker piece of glass in the transfer slide, which is used to carry the real object. The cover fragment is the small round or square thin one.
5. Mounting is a general term for a set of things, including slides, coverslips and loaded objects
