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.

The main oxides of fly ash in China's thermal power plants are SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 and so on. With the development of electric power industry, the discharge of fly ash from coal-fired power plants is increasing year by year, and it has become one of the industrial wastes with large displacement in China. If a large amount of fly ash is not treated, it will produce dust and pollute the atmosphere. If discharged into the water system, it will cause the silting of the river, and the toxic chemicals in it will also cause harm to human and biological. But fly ash can be used as resources, such as as an admixture of concrete.

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.

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.

White clay , also called kaolin or kaolinite, was discovered in China, on Kaoling Hill, although we can find it all over the world.Originally white clay was used for therapeutic purposes, but today white clay is one of the most used ingredients in natural cosmetics . Its qualities are not limited to external use, it is also known for its medicinal and healing qualities when ingested.

White clay can  eliminate cellulite and stretch marks , all this by applying it to the affected area and letting it rest, wrapping it with transparent paper (normally used in the kitchen) for a few minutes, then rinsing it with warm water.This clay has  anti-inflammatory  and cell regeneration properties , which helps combat stretch marks on the skin. It also eliminates impurities and gives it a much healthier appearance.

provides a layer of protection against ultraviolet rays and controls pests that affect crops and decorative plants. It stands out for its  purity, white color  and its  easy dispersion in water , making it an ideal product to spray and attack aerial pests (flies, mosquitoes). Here you can buy 100% pure and natural kaolin  from the Bioky brand, especially recommended for small-scale agriculture and crops.Specifically, kaolin is an aluminum silicate, a soft, plastic clay, composed of fine-grained lamellar particles. Its texture is a  very fine micronized powder  that makes it easy to apply. Thanks to its benefits, it is a product that is booming and offers a large number of benefits, both for obtaining safe raw materials and for guaranteeing the production of organic crops.At a regulatory level, according to Regulation (EC) No. 1107/2009 of the European Parliament and of the Council , kaolin (aluminum silicate) is considered a conventional and low-risk active substance . Its function is as an insect repellent . In addition, this product can be applied for phytosanitary protection in the field of Organic Agriculture, as dictated by Implementing Regulation 2021/1165 .

Kaolin is a type of clay used in the aesthetic treatment of wrinkles, dark circles, dry and/or oily skin, blemishes and stretch marks, and can be used in the form of a paste or facial mask.The use of clay-based products for medicinal and aesthetic purposes is known as clay therapy, which can be carried out with different types of clay, including kaolin, also known as white clay.If you have doubts about the use of kaolin on the skin, it is recommended to consult a dermatologist, who is the most ideal doctor to indicate the care that should be taken with any type of skin.

White clay, also called kaolin, is a widely used ingredient in skin cosmetics . Due to its astringent effect and its mineral content, it is used as an ally to regulate excessive sebum production, remove dead cells and provide luminosity to the skin.In fact, it is also related to the stimulation of cell regeneration and the prevention of premature aging. While many of its benefits are supported only by anecdotal evidence, some studies suggest that it does have positive effects on the skin. Let's see.

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.
