Perlite - a breed that can be found in areas of volcanic eruptions.It is formed where hot lava comes in contact with the ground at the edge of its flow.Due to the fact that the red-hot flow is fastest cools, it forms obsidian - volcanic glass.Further, if the water is exposed to the effects of obsidian, and it turns out he is hydrated substance perlite - obsidian hydroxide.
perlite Chemical composition (silica, water, and other elements) provides a kind of "popcorn" at a temperature of 1200 degrees when the water expands substance, and the amount of perlite is increased to 20 times.It turns out the so-called perlite, which has unique physical properties.It refractories, chemically inert, light, can not be exposed to the mold, rodents and microorganisms.Perlite - this is the material date for construction, medical, oil and gas industry, metallurgy.He successfully applied at temperatures from minus 260 to plus 1,000 degrees.
perlite is mainly used to backfill voids in the insulation works, during finishing operations to improve the sound insulation (3 cm perlite replaces the 15 cm brick and absorbs noise of 51 dB), to facilitate the construction of solutions for the specific weight, or improve the quality ofsteel alloys.
After processing, heat expanded perlite keep their properties indefinitely.In appearance perlite - a white substance in pellets of 0.1 to 1.0 cm, having a bulk density 50-150 kilograms per cubic meter.Maybe that's why the name of perlite derived from the word "gem" - "Pearl" (fr.).
How perlite good stuff?Perlite - a completely eco-friendly product.It includes supplements in the form of potassium, sodium, aluminum, iron, calcium, sodium, to successfully apply this product in agriculture, especially in areas with infertile land and arid climate.Agroperlit used for loosening soil, in addition to a variety of substrates, as well as the substance, retaining up to 600% of its own weight of water, thereby reducing the amount of irrigation.Perlite is used for plants in this direction of agriculture as hydroponics.When we eat some, such as the Dutch vegetables or berries (strawberries), it had no idea that they were not grown in the ground and in containers, which fed a nutrient solution.And part of the containers were filled with perlite it.
perlite produced a variety of filters and sorbents, which have high absorbency, and therefore used to remove stains of oil liquids with water surfaces, wastewater emissions, improve the quality of drinking water, and even the localization of radionuclides in the soil.Furthermore, materials made of a non-vacuum insulation can produce cryogenic units, including metals for the separation of air into nitrogen and oxygen.
