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.

Coral sand is a fragment of coral or shell that consistently releases calcium carbonate and comes in a variety of sizes and sizes. The biggest feature of coral sand is that it is rich in micropores, suitable for the survival of a large number of biochemical bacteria, and can be used as a filter material.

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.

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.

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,

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.

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.

Pine bark can adjust the acidity and alkalinity of the soil, provide nutrients for the growth of plants, and pine bark planting can maintain good water permeability and air permeability of the soil.

White clay or kaolin is a rock powder originally discovered in China on the Kao-ling hill with multiple uses thanks to its multiple properties and versatility. Initially it was used for therapeutic purposes, but its magnificent properties extended its use to a cosmetic level as well. In the cosmetic environment it is used as an ingredient thanks to its multiple benefits, among which its purifying, calming and revitalizing effect stands out. Furthermore, among the benefits of white clay, you knew that it is suitable for all skin types and also has a pH very similar to that of our skin. Surely you already know that there are countless types of clay such as green, red, pink and black. But we are going to focus on the white one because this product has proven very useful in fighting very common skin problems.

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.
