Descriptions expansion glass beads is an inorganic glassy mineral materials, through a multi-stage production of silicon carbide electric heating tube processing technology, irregular spherical particles, the internal structure of porous hollow, glassy surface of the closure, shiny smooth, stable physical and chemical properties, a lightweight, thermal insulation, fire resistance, high temperature, anti-aging, small, excellent water absorption properties, can replace ash floating beads, glass beads, perlite, polystyrene and many other Traditional lightweight aggregate used in different Products. Is a new type of environmentally friendly high-performance inorganic lightweight insulation. Applications can replace ash floating beads, glass beads, perlite, polystyrene and many other traditional lightweight aggregate, used in industry, agriculture, chemical industry, metallurgy, building materials, and other areas. Scope 1. Suitable for reinforced concrete, the wall insulation aerated concrete block, brick, sand-lime bricks wall. 2 roof insulation. 3 energy saving old buildings. 4 basement, garage, fire exits, granary, stairwells, factories and other fire insulation works. 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.
