Quartz sand is quartz particles formed by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, which is a hard, wear-resistant and chemically stable silicate mineral. The color of quartz sand is milky white, or colorless translucent, Mohs hardness 7.Common specifications are: 0.5-1mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, 10-20 mesh, 20-40 mesh, 40-80 mesh, 100-120 mesh.

Coated sand is mainly made of high-quality natural quartz sand as raw sand, thermoplastic phenolic resin, ulotropine and reinforcing agent as raw materials. According to the different technical requirements of users, the ratio is appropriately adjusted in terms of curing speed, film removal, fluidity, collapsibility, casting surface finish, storage and so on. It is one of the best modeling materials for cars, tractors and hydraulic parts.

Calcium powder can be divided into: heavy calcium powder, light calcium powder, active calcium powder, flue gas desulfurization calcium powder, ultra-fine calcium carbonate and so on.

Dolomite powder is an anhydrous carbonate mineral powder, mainly composed of calcium and magnesium carbonate. It can be used as raw materials for the production of high-grade glassware, medical bottles, and optical glass.

Emery, SiC, also known as silicon carbide. Pure is a colorless crystal. Density 3.06~3.20. It's very hard, about 9.5 degrees Morse. Generally, it is a colorless powdery particle. After grinding, it can be used as grinding powder, polishing paper, and friction surfaces for grinding wheels and whetstones. It is made by heating sand and carbon in an electric furnace.

Microsilica powder is a new kind of material,Microsilica powder is a new material with high surface area, a large number of pores, high and low temperature stability, biological inertness and so on. Its application field is very wide, can be used in petroleum catalyst, environmental protection materials, biomedicine and many other fields.

Glass sand is divided into colored glass sand and transparent glass sand, transparent glass sand looks like white sugar, glass sand is used for glass surface decoration, such as glasses, vases, lampshades and so on. Glass sand is fused together with glass workpieces to form a concave and convex three-dimensional surface,

Alumina powder is made of liquid aluminum hydroxide by extrusion solidification, which contains a variety of elements, and the content is high, the overall density is higher than the general aluminum powder. The surface of alumina powder is closer to the ideal surface than that of other metal powders, so it has good exhaust performance. The particle size of alumina powder is generally 90-100 microns, has good suspension, no load charge, can be oxidized at low temperatures, and has excellent electromagnetic characteristics.

Fluorite (Fluorite) is also called fluorite. A mineral commonly found in nature that is symbiotic with many other minerals and occurs in many parts of the world, [1] with five effective varieties. The main component is calcium fluoride (CaFz). Crystallized into octahedrons and cubes. The crystal is glassy, bright and changeable color, brittle quality, Mohs hardness of 4, melting point of 1360℃, with complete cleavage properties. Some samples can emit light when subjected to friction, heating, ultraviolet irradiation, etc.

Colored sand is divided into natural colored sand, sintered colored sand, temporary dyed color sand, permanent dyed color sand. Its characteristics are: bright color, acid and alkali resistance, ultraviolet resistance, do not fade. Natural color sand: It is crushed by natural ore, which does not fade but has more impurities. Temporary dyeing color sand: bright color, easy to decolorize.

Wheat flour powder is widely used in medical care, food, beverage, water purification, sewage treatment, anti-corrosion, deodorization, preservation, decontamination, porcelain production, planting and aquaculture and other fields.

mineral powder is a general term for stone powder and its substitutes that meet engineering requirements. It is the product of grinding ore processing, is the first step of ore processing and smelting, and is one of the most important steps. The hydrophilic coefficient of mineral powder is the ratio of the volume of expansion per unit of mineral powder in the same water (polar molecules) and the same volume of kerosene (non-polar molecules). Hydrophilic coefficient of mineral Powder in Highway engineering < The mineral powder of 1 is called alkaline mineral powder.

Shell sand is a common building material, which is made of crushed shells and has a certain hardness and durability. Shell sand has a wide range of uses and can be used in many aspects such as interior walls, exterior walls, floors and ceilings.

Quartz stone is a non-metallic mineral, which is a hard, wear-resistant and chemically stable silicate mineral. The color of quartz sand is milky white, or colorless translucent, Mohs hardness 7.Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media and other industries.

The use of emery is very wide, for example, the glass industry, used to grind glass rough edges, the stone industry is used to grind marble, the metal industry is used for sandblasting, rust removal, grinding, etc., and we use emery made of wear-resistant floor, used in the field of industrial floor.

Iron powder is one of the most important metal powders. Iron powder is the largest in powder metallurgy production, and its consumption accounts for about 85% of the total consumption of metal powder.

Silica ash, also known as silica powder, also known as micro-silica powder or silica ultrafine powder, generally referred to as silica ash. Silica fume is a kind of ultrafine silica powder material formed by the rapid oxidation and condensation of SiO2 and Si gas and oxygen in the air during the smelting of ferrosilicon alloy and industrial silicon.

Sand casting is an economical way to produce parts in a variety of metals. Shell mold casting can be an alternative process to consider given specific part design needs. This blog post introduces the shell mold casting process and compares it with sand casting so readers may understand their respective strengths and limitations.

Gulf State Park holds some of the most endangered archaeological deposits in the State of Alabama. Even though these sites are located within the protected area of the park, rising sea levels and damage caused by severe coastal storms will one day likely erase what remains of these fragile reminders of the people who were here before us. Even today, understanding the complex system of interconnected waterways, residential sites, and mounds is made that much more difficult by the centuries of storms and historic changes to the landscape.

Ceramsite is made of clay, slate, shale, coal gangue, and industrial solid waste and other raw materials, and is sintered by ceramics.
