Chong Hing perlite perlite Description: perlite (perlite) which is composed of glassy rock crushing and roasting hot, white bead-like loose particles. Non-toxic, odorless, nonflammable, non-corrosive. Because of its very low thermal conductivity and chemical stability, reliable, good flowability and filling of very low bulk density. And is widely used in washing powder, industry, agriculture, defense, environmental, chemical, food, construction and other industries. Especially in cryogenic engineering, ASU (oxygen cold box), and other integrated projects have other insulation materials irreplaceable superior performance. Chong Hing perlite perlite Chemical Composition: SiO2 (silica) 75.45% Fe3O2 (iron oxide) 0.73% MgO (magnesium oxide) 2.05% Al2O3 (alumina) 10.57% Na2O (sodium oxide) 7.78% K2O (potassium) 7.78% CaO (calcium oxide) 1.69% Chong Hing perlite 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 of not less than 90% (wt% ratio) 0.5 mm throughput: 50 Type 0.05 mm maximum 8% 60 type 0.05mm maximum moisture content of 8% by mass (weight% ratio): 50 Type ≤0.5-1% 60 type ≤0.5-1% angle of repose (when stacked height 100mm): 33-37 loading process increase in density: Manual wind ≤35% ≤25% thermal coefficient (atmospheric temperature in the 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, customer unit personnel to detect and use to avoid entering the respiratory tract and the eyes. The factory provides a variety of 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 board, building with glass beads, perlite Cleaner, opening perlite, closed-cell perlite, expanded perlite and other non-metallic mineral products, according to customer request processing various indicators of perlite products.
