Today, dozens of large-scale stone industry bases have been established in various parts of my country, and a modern stone industry system has been initially established. The annual production of various stone products in China has reached more than one billion square meters. According to our current stone consumption in China With a utilization rate of 70%, the remaining 30% of leftovers is also an astonishing amount. Most of these leftovers, debris, pulp residue, etc. are treated as waste, which is very regrettable. If these discarded stone scraps are only disposed of by simple landfill, it will take up a lot of land resources, which is wasteful and worthless. In fact, these stone wastes are also very good raw materials for production. We can reuse them through various comprehensive processing and utilization projects, turn waste into treasure, and create new value.
So what can these discarded scraps be used for? The editor is here to throw bricks and introduce jade, and introduce several good processing solutions for you: Marble floor tile mosaic example Figure 01. Used as a mosaic material Mosaic is a very ancient decoration method, the principle is to cut and collage different textures and colors Stone, forming a unique artistic pattern. Through parquet, the ingenious fusion of floor tiles, wall tiles, and background walls can be realized. Compared with a single decorative effect, the plane level will be fuller. The technology is booming with the advancement of modern design making techniques.
At present, many domestic engineering projects in hotels, restaurants, shopping malls, airports and other fields tend to use stone parquet to enrich the decorative effect. This makes the amount and variety of stone parquet more and more, and the patterns are more and more complex. The waste and leftover materials produced in the stone processing process are the good source of stone mosaic materials, whether it is marble, granite, or various artificial stones, they can all be used.
After processing the stone leftovers, we can make full use of waste resources and achieve ecological and economic effects of environmental protection and conservation. At the same time, we can make the whole environment full of warmth and vitality through the beauty of stone and beautiful patterns. vitality. 02. Stone furniture, decorations, and works of art can be used to make lamp holders, calendar boards, pen holders, inkstones, rulers, painted screens, and various door and table handles with leftover materials, which are elegant and beautiful. 04. Used as electrical insulation material. The leftover materials of electrical appliances can be made into electric gates, light switches, switch cabinets, etc. It is one of the indispensable materials in the electric power industry, and its products are quite popular.
05. Made into terrazzo Terrazzo is a product made by mixing gravel, glass, quartz stone and other aggregates into binders to make coagulated products, and then surface ground and polished. Traditional terrazzo generally uses cement as a binder, so the surface is rough, easy to weather and abrasion, and there are great limitations in color expression. In recent years, since people began to replace cement with epoxy resin, a series of defects of terrazzo have been perfectly solved, the material is more delicate, it has become smooth and bright, and the color also shows a bright beauty.
In addition, it is lighter in weight, so you don't have to worry about being overweight when it is installed on the second or third floor. Today, new types of terrazzo are available in prefab and cast-in-place construction. Prefab terrazzo is easy to install and construct, and is similar to ceramic tile. The use of new terrazzo is more extensive than traditional terrazzo, and almost all families that use tiles and floors can be replaced by new terrazzo.
The development of terrazzo is of great significance. At present, there are a wide variety of floor and wall material products in our country, and new terrazzo should occupy a place. In addition, the development of high-end terrazzo technology can turn waste into treasure, realize sustainable development, and promote the development of synthetic stone and multifunctional stone.
06. Made of autoclaved aerated concrete block The autoclaved aerated concrete block is a kind of lightweight porous, with the characteristics of light weight, high strength, heat preservation, heat insulation, sound absorption, fire prevention, sawing and planing processing, etc. A new type of building material, the general mass is 500-700 kg/m3, only equivalent to 1/4-1/3 of clay bricks and lime-sand bricks, 1/5 of ordinary concrete, is a lighter type of concrete, suitable for Infill walls of high-rise buildings and load-bearing walls of low-rise buildings. Using this material can reduce the self-weight of the entire building by more than 40% compared with that of ordinary brick-concrete structures. Due to the reduced weight of the building, the earthquake destructive force is small, so the earthquake resistance of the building is greatly improved.
Lime, fly ash, slag, gypsum, cement, sand, gas generating agent, air bubble stabilizer and regulator can be used as the main raw materials for making autoclaved aerated concrete blocks.
