Construction and Agriculture Expanded Vermiculite for Hydroponic Potting Media

Product Description

Product Description
Vermiculite is a natural mineral that expandsunder high temperatures.Vermiculite cancreate excellent pore structure in the matrix,making it have good breathable pores

Vermiculite is a layer-structured metamorphic rock of gibbsite silicate. Rich in magnesium. It comes from hot-liquid-eroded or weathered phlogopite. When it is heated to lose water and expands, lt turns curvingas a leech. Therefore is called vermiculite. It can be divide into original vermiculite and expanded vermiculite. It can also be divided into golden vermiculite and silver white vermiculite according to its color Vermiculite is a mineraloid of hydrated laminar magnesium-aluminum-ironsilicate. Its chemical composition greatly varies and chemical formation could be simplified as ( Mg.Fe..Fe.. )3[(SiA)4O10][OH]24H2O. When heated to a temperature of about 850-950ºC, it instantly expands (exfoliates) up to 15-25 times as water flashing into steam, maximum 30 times its original bulk volume. There is a color change during expansion from golden brown into silver white depending upon the composition of the vermiculite and temperature. With such prominent characteristics as being fireproof, heat insulating, sound and moisture absorbing, non-toxic, lightweight and disease free, it is widely used in construction, chemical industry, petroleum, electronics, light industry, environmental protection and as medium of agricultural chemical products etc. Vermiculite is a natural, inorganic, non-toxic mineral that will expand under the action of high temperature. Vermiculite can be divided into raw ore vermiculite and expanded vermiculite according to the stage. According to the color classification, it can be divided into golden yellow vermiculite and silver white vermiculite.

Exfoliated vermiculite in the process of high temperature roasting , they can expand many times, and the average density of the expanded vermiculite is about 100-130kg/m3, they have small air separation layer , so they are good construction materials of heat preservation , thermal insulation sound absorption , and corrosion proof , and also industry loading material , coating, anti-fire materials. E xpanded vermiculite can extensively used in many industries such as construction, metallurgy , chemical industry , light industry , machinery , electric power, petroleum, environment protection communication , transportation and horticulture. M ain applications: 1. Construction materials: Light materials such as light concrete materials, light calcimine and light mortar. 2. Heat resisting material : Wall materials, anti-fire board, anti-fire mortar, firebrick, and brake linings. 3. Heat preservation , thermal insulation and sound absorption materials: Underground pipeline, heat preservation material used in hothouse pipeline, decoration material used in upholstery and tunnel, also wall and ceiling in the public. 4. Metallurgy: Steel frame cladding materials, removal of slag when manufacture of iron and foundry5. Agriculture , forestry and horticulture: Golf course lawn, seed preservation agent, soil regulation agent, wetting agent, plant growth agent, feed additives, horticulture mixture, fishing and bait. 6 other aspects: Adsorptive material , filter aid, active carrier of chemical and chemical fertilizer , sewage treatment, adsorption of seawater oil pollution , cigarettes filter and explosive density regulators.
