Why the need for quartz sand graded ?

Quartz sand Fractionated: classification

called so that the sand is not in vain, silica particles are of different sizes, and the use of fractions of a certain size are appropriate.Important role plays and shape.For the most part, graded silica sand divided into two groups - the building and molding, but is used much more widely.It is made of glass windows, and medical bottles, as well as the chemical container, the density of quartz sand makes it suitable for high-quality filters.

quartz sand obtained from the sea, has a break in a round shape, as well as a river, and a career and gully workings obtain fractions angular shape.

For those who need to transport the material over a long distance, great interest is the proportion of quartz sand.It corresponds to 2.7 g / cm3, with sufficient looseness cubic meter of sand will weigh 1,500 kilograms.However, for the most part sold quartz sand in bags, packed by 25 and 50 kilograms.Importantly, the material in the bag is filled, graded, ie, the individual particles have a size within a certain permissible value.

Quartz sand: used in construction and not only

Fine quartz sand density is considerable, but the way you can use it, depends not only on the quantity but also the shape of the individual fractions.For example, if you want to use for sandblasting works silica sand, use for this purpose, the material extracted from the sea or river, it is inefficient due to its roundness.But for the finishing of such sand with medium and large size fractions (0.63 to 2 millimeters) can be an excellent mix, for example, decorative plaster.

most quality is considered to be white quartz sand, which has no impurities.This material does not require further enrichment and chemical treatment. White sand is used not only in construction, when, for example, to get self-leveling floors of high strength, but in landscape design .The direct opposite of it is a silica sand mold, whose quality leaves much to be desired.For the most part characterized by a fine grain size, the molding material used for backfilling trenches in construction, as well as for the manufacture of molds.

Where necessary, dry quartz sand?

to be used in various areas such as construction and manufacturing, quartz sand should be thoroughly dried.It is during the drying of the material is purified of various impurities, including by clay and dust.However, among other things, the aforesaid process is necessary for another purpose.Sand dry quartz easier amenable to fractionation, followed by packaged in bags or big-begam calculated per ton of content.

Dry sand is essential for strewing tracks as garden, without which it will not do any landscape suburban area, and sports, along with park in the city .Also, quartz sand, especially color, is required for road marking, in particular - for pedestrian crossings and traffic islands.They are sprinkled with a soft exterior tiles, to improve durability, and the back side, which is necessary to successfully transport the sheets from sticking together.
