50-70 mesh furnace insulation materials perlite perlite

Chong Hing perlite perlite Description: perlite (perlite) It is made by crushing the glassy rock roasting and high temperatures, a white bead-like loose particles. Non-toxic, odorless, nonflammable, non-corrosive. Because of its very low thermal conductivity and reliable chemical stability, good liquidity and low packing density of. And is widely used in washing powder, industry, agriculture, national defense, environmental protection, chemicals, food, construction and other industries. Especially in cryogenic engineering, air separation equipment (oxygen cold box), and other integrated projects with additional insulation material irreplaceable excellent performance. Chong Hing Perlite perlite Chemical Composition: SiO2 (silicon dioxide) 75.45% Fe3O2 (iron oxide) 0.73% MgO (magnesium oxide) 2.05% Al2O3 (alumina) 10.57% Na2O (sodium hydroxide) 7.78% K2O (potassium) 7.78% CaO (calcium oxide) 1.69% Chong Hing perlite perlite 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: 1.0mm-0.05mm 50 type 60 type 90% less than 1.0mm-0.05mm particle size of less than 90% (wt% ratio) 0.5 mm throughput: 50 Type 0.05 mm 60 type 0.05mm maximum 8% maximum moisture content of 8% by mass (weight% ratio): 50 Type ≤0.5-1% 60 type ≤0.5-1% angle of repose (when stacking height 100mm): 33-37 packing process increase in density: Manual pneumatic ≤35% ≤25% thermal coefficient (atmospheric temperature at 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, tap density maximum. [Reminder] perlite relatively light, easy to fly, the customer unit personnel in the detection and use to avoid entering the respiratory tract and the eyes. The factory provides various uses zeolite powder, bentonite, lithium-bentonite, sodium bentonite, horticultural perlite, air separation plant with perlite, do washing powder with pearlescent sand, perlite filter aid, perlite insulation boards, building with glass beads, perlite Cleaner agent, opening perlite, closed-cell perlite, perlite and other non-metallic mineral products, customers can request the production of various indicators of perlite products.
