3.Perlite in the steel and Foundry Industries 

Perlite insulation is used in high temperature applications in the steel and foundry industries such as ladle topping, hot topping and risering, in topping compounds, in exothermic and insulating shapes, as a cushioning agent, in molding sand and in the manufacture of refractory blocks and bricks.

4.Agriculture perlite application

 

THE ADVANTAGES OF AGRICULTURAL PERLITE

· Improves soil aeration and drainage.

· Makes moisture and nutrients readily available to plants.

· Inorganic and does not deteriorate.

· Serves as an insulator to reduce extreme soil temperature fluctuations.

· Has essentially neutral PH of 6.5 to 7.5.

· It is sterile and free of weeds and disease.

· It is clean, odorless, lightweight.

 

Benefites of Hydroponic culture

· Horticultural perlite provides more constant moisture status aroun the roots at all times irrespective of we            ather or stage of root growth.

· Perlite ensures more even watering throughout the grwoing area.

· Thera is less probability of over-watering with horticutlural perlite.

· Perlite culture avoids wasting of water and nutrients.

· The use of perlite eliminates the need to grade growing floors accurately.

5.Construction Applications

Because of perlite's outstanding insulation, light weight, fire retardant and sound control characteristics and its being rot, vermin and termite resistant perlite is widely used in the following construction applications.

· Loose fill insulation

· Portland cement and gypsum plasters

· Underfloor insulation

· Concrete roof decks

· Chimney Linings

· Fireproofing

· Blocks

· Pipe insulation

6.Perlite Filter aid

The properties which give perlite filter aids a competitive advantage over competitive products are their not toxicity and low bulk density. Their low bulk density is very important for the cost effectiveness of the process because at the filtration bed it is the volume of filter aids that matters and not their mass. Perlite filter aids are also preferred in many industries because they allow filtration equipment to filter liquids at a faster rate and for a longer time without the filter septum to be blocked.Perlite filter aids are used in the filtration of  wine, sugar and starch, beverages, edible oil, as well as pharmaceuticals and chemicals.Expanded perlite is an excellent filter aid, characterized by high purity and inertness. It has the property of forming pre-coats and cakes of a large number of pores, which can trap effectively the various solid impurities from the liquid to be filtered. Their main advantages over competitive products are their non-toxicity and low bulk density. Perlite filteraids also facilitate the fast rate of filtration and high clarity of the liquid

 

 

7.The spec of  Expanded perlite

 

  • Agriculture and horticulture grade:1-3mm,2-4mm,3-6mm,4-8mm
  • Perlite filter aid grade: 30-50mesh,50-70mesh,70-90mesh,90-120mesh,120-200mesh etc
  • Construction and industry grade: 30-50mesh,50-70mesh,70-90mesh,90-120mesh etc
  • Special expanded perlite: water-resistant expanded perlite 
 

8.Packing and Loading

 

1.Generally we tend to use Pp bag,100 L/bag to load the expanded perlite.

   And the jumbo bag,1-1.5M3/bag was also been used by our customer before.

 

2.The expanded perlite is sold by it's volume,so the unit of price will be USD$   /Cubic meter

 

3.We can load 30m³ to one 20 FCL and 70-72 m³ to one 40HQ.
