Product Description

Wholesale price Hydroponics Expanded Perlite for Agricultural growing media
Perlite is a volcanic eruption of acid lava , vitreous rock formed by rapid cooling , because  of its pearl fissure structure . Perlite ores include perlite , obsidian and turpentine . The difference among the three is that perlite has a circular arc crack formed by condensation , which is called perlite structure , with a water content of 2% and 6% ; Turpentine has a unique  gloss of turpentine and water content of 610%; obsidian has a glass gloss  and shell-like fracture , Water content is generally less than 2.

Perlite Application:

Expanded perlite for horticultural 

In horticultural applications, perlite is used in expanded perlite ,which is used as a component of soilless growing mixes as it provides aeration and optimum moisture retention for superior plant growth. For root cuttings, 100% perlite is used. Studies have shown that outstanding yields are achieved with perlite hydroponic systems. Other benefits of horticultural perlite are its neutral pH and the fact that it is sterile and weed-free. In addition, its light weight makes it ideal for use in container growing. Other horticultural application of perlite includes as: fertilizer , herbicides and pesticides carriers and for seed pelletizing. Horticultural perlite is as useful to the home gardener as it is to the commercial grower. It is used with equal success in greenhouse growing, land-scaping applications and in the home in house plants.
 

Construction industry:

Can be used as Aggregate concrete; lightweight, heat insulation, heat insulation, sound absorption board; fireproof roofing and light frost, shock resistance, fire prevention, anti radiation of high-rise building wall filler, mortar and other building materials; various kinds of industrial equipment and pipe insulation layer; the inner wall of the various cryogenic, cold storage engineering; low boiling point liquid, gas storage wall and transport of inner wall

Filter aid and filler:

Molecular sieve, filter agent, detergent; used for wine, making fruit juice, syrup, sugar, vinegar and so on food processing manufacturing industry filtering fine particles, algae, bacteria, etc.; all liquid purification. The purified water can be harmless to people and livestock to; chemical industrial plastic, spray paint to poison, purification of waste oil, oil dewaxing and fractionation of alkane and hydrocarbon; as filling agent in paint enamel, enamel, plastic, resin and rubber industry; chemical reaction in the catalyst, and well grouting mixture

Forestry and Horticulture:
