Expanded and vitrified ball are due to the vitrification of the surface to form a certain particle strength, the physical and chemical properties are very stable, the aging and weather resistance is strong, and they have excellent heat insulation, fire protection and sound absorption properties. They are suitable for light filling aggregates and heat insulation and fire protection in many fields. ﹑Sound-absorbing and thermal insulation materials. In the building materials industry, using Expanded and vitrified ball as lightweight aggregates can improve the fluidity and self-resistance of the mortar, reduce the shrinkage of material properties, improve the overall performance of the product, and reduce the overall production cost.
Expanded and vitrified ball are an inorganic glassy mineral material processed by multi-stage silicon carbide electric heating tube production technology. They are irregular spherical particles with internal porous cavity structure, vitrified closed surface, and smooth luster. Stable physical and chemical properties, light weight, thermal insulation, fire resistance, high and low temperature resistance, anti-aging, low water absorption and other excellent characteristics, can replace fly ash floating beads, glass beads, polystyrene particles and many other traditional lightweight aggregates. Application in products. It is an environmentally friendly high-performance new inorganic lightweight thermal insulation material.
Expanded and vitrified ball | 1. Low density(80~120kg/m³)2.Low water absorption
3.High particle strength 4.Low heat conductivity |
3. Low water absorption, easily controlled in mortar, low shrinkage, no hollowing and cracking, stable thermal property and mechanical property, increase the mortar service life. |
1.Suitable for internal and external wall insulation of reinforced concrete, aerated concrete blocks, porous bricks, lime-sand bricks and other walls.
2.The roof insulation layer.
3.Energy-saving renovation of old buildings.
4.Fireproof and thermal insulation projects such as basements, garages, fire passages, granaries, stairwells, and workshops.
