Silica sand is used frequently in water filtration systems where it is the primary filtration medium to extracts solids from contaminated water. Filter silica sand consists of hard, durable, and dense grains of predominantly siliceous material that will resist degradation during handling and use.
Paint formulators select micron-sized of silica sands to improve the appearance and durability of architectural and industrial paint and coatings. High purity silica contributes essential performance properties such as brightness and reflectance, color consistency, and oil absorption. In the aspect of architectural paints, silica fillers improve tint retention, durability, and resistance to dirt, mildew, cracking and weathering. Low oil absorption allows increased pigment loading for improved finish color. In the aspect of marine and maintenance coatings, the durability of silica imparts excellent abrasion and corrosion resistance.
Silica that has been ground to fine size is an ingredient of most clay bodies and is a major constituent of ceramic glazes. Typical everyday products include tableware, sanitaryware, ornaments and wall and floor tiles.
Silica sand is one of the key components for almost all common commercial glasses. It is used to produce flat glass for building and automotive use, container glass for foods and drinks, and tableware. Besides that, it also used to produce other specialty product such as test tubes and other scientific tools, incandescent and fluorescent lamps, television and so on.
Our playground sand is an economic decision that municipalities and schools have made, even though the initial cost, at point of purchase, is more expensive than inferior sand products available from other local sources. Not having to perform regular rototilling maintenance throughout the lifetime of our protective safety surfacing pays off in the long term.
Silica is one of the refractory materials. It has a higher melting point than iron, copper and aluminum. The refractoriness helps to resist high temperatures without breaking down or fusing thus facilitating to get sound casting. This enables castings to be produced by pouring molten metal into moulds made out of silica sand.
Sand is used in mortars, tile adhesive, flooring, non shrink grout, hardener, tile grout and roofing tiles. Silica sand is the main structural component in a wide variety of building products. It can be used in flooring compounds, mortars, specialty cements, stucco, roofing shingles, skid resistant surfaces and asphalt mixtures to provide packing density and flexural strength without badly affecting the chemical properties of the binding system. On the other hand, it also carry out as a functional extender to add durability and corrosion resistance and weathering properties in epoxy based compounds, sealants and caulks.
Sand plays an important role in the production of a wide variety of ferrous and non-ferrous metals. In the aspect of metal production, silica sand work as a flux to lower the melting point and viscosity of the slag to make them more reactive and efficient. Lump silica is used either alone or in combination with lime to achieve the desired base/acid ratio required for purification. These base metals can be further refined and modified with other components to attain specific properties such as high strength, anti-corrosion/corrosion resistance or electrical conductivity. Besides that, ferroalloys are crucial to specialty steel production and silica sand is used by the steel and foundry industries for de-oxidation and grain refinement.
In the face of growing demand for golf courses across the developing and developed economies, good silica sands plays a critical role in the golf bunkers and putting green. Quality has to be ensured for uniform and consistent surfaces to be formed for the best enjoyment and performance of golfers at premier clubs.
