Description: perlite (perlite) It is made by firing a glassy rock crushing and high temperature materials, a white bead-like loose particles. Non-toxic, odorless, nonflammable, non-corrosive. Because of its low thermal conductivity, chemical stability and reliability, good flowability and filling of low density. Which is widely used in washing powder, industry, agriculture, national defense, environmental, chemical, food, construction and other industries. Especially in cryogenic engineering, air separation equipment (oxygen cold box), and other integrated projects with other insulation materials irreplaceable superior performance. Perlite Chemical Composition: SiO2 (silica) 75.45% Fe3O2 (iron oxide) 0.73% MgO (magnesium oxide) 2.05% Al2O3 (aluminum oxide) 10.57% Na2O (sodium oxide) 7.78% K2O (potassium ) 7.78% CaO (calcium oxide) 1.69% perlite product performance indicators: bulk density: 50 Type 50kg / cubic 60 type 60KG / cubic tap density: 50 Type 60kg / cubic 60 type 70KG / cubic particle size (weight% ratio) 1.00 mm Throughput: 50 type 1.0mm-0.05mm less than 90% 60 type 1.0mm-0.05mm particle size less than 90% (wt% ratio) 0.5 mm Throughput: 50 type 0.05mm maximum of 8% 60 type 0.05 mm maximum moisture content of 8% by mass (wt% ratio): ≤ 0.5% 60 50 type type angle of repose ≤ 0.5-1% (stacking height of 100mm) :33-37 increases the density of the filling process: the wind manually ≤ 25% move ≤ 35% thermal conductivity at (atmospheric temperature 77k-301k average): 50 Type 0.022-0.025W/mk 60 type 0.023-0.026W/mk temperature: -200-800 ℃ Note: The table bulk density, The tap density is maximum. Our purpose is to provide a variety of horticultural perlite, perlite air separation device, do washing powder with pearlescent sand, perlite filter aid, perlite insulation board, construction glass beads, perlite and other products, according to customer request processing production of various indicators of perlite products.
