Our company produces various dedusting equipment, including electrostatic dedusting bag dedusting and cyclone dedusting. The design, maintenance, transformation and construction progress are fast and the quality is guaranteed, Floating beads are fly ash hollow balls that can float on the water surface. They are gray-white, thin and hollow, and light in weight. The bulk density is 720kg/m3 (heavy), 418.8kg/m3 (light), and the particle size is about 0.1 mm, the surface is closed and smooth, the thermal conductivity is small. The chemical composition of the floating beads is mainly silicon dioxide and aluminum oxide. Raw materials for refractory High refractoriness. The main chemical components of the floating beads are silicon and aluminum oxides, of which silicon dioxide is about 50-65%, and aluminum oxide is about 25-35%. Because the melting point of silica is as high as 1725 degrees Celsius, the melting point of aluminum oxide is 2050 degrees Celsius, both of which are high refractory materials. Therefore, floating beads have extremely high refractoriness, generally reaching 1600-1700 degrees Celsius, making them an excellent high-performance refractory material. Lightweight, thermal insulation. The wall of the floating bead is thin and hollow, and the cavity is semi-vacuum, with only a very small amount of gas (N2, H2 and CO2, etc. ), and the heat conduction is extremely slow and extremely small. Therefore, the floating beads are not only light in weight (bulk density 250-450 kg/m3), but also excellent in thermal insulation (thermal conductivity at room temperature 0.08-0.1), which lays the foundation for them to show their talents in the field of lightweight thermal insulation materials. High hardness and strength. Because the floating beads are hard glass bodies formed by silicon aluminum oxide mineral phases (quartz and mullite), the hardness can reach Mohs 6-7, the static pressure strength is as high as 70-140MPa, and the true density is 2.10-2.20 g/cm3. Comparable to rock. Therefore, the floating beads have high strength. Generally, lightweight porous or hollow materials such as perlite, zeolite, diatomite, pumice, expanded vermiculite, etc. Have poor hardness and strength, and thermal insulation products or light refractory products made of them have strength Poor disadvantage. Their shortcomings are precisely the advantages of floating beads, so the floating beads have more competitive advantages and wider uses. Fine particle size and large specific surface area. The particle size of the naturally formed beads is 1-250 microns. The specific surface area is 300-360cm2/g, which is similar to cement. Therefore, the floating beads can be used directly without grinding. The fineness can meet the needs of various products. Other lightweight thermal insulation materials generally have large particle sizes (such as perlite, etc. ), if they are ground, the capacity will be greatly increased, and the thermal insulation will be greatly reduced. In this regard, floating beads have an advantage. Excellent electrical insulation. The floating beads after the magnetic beads are selected are excellent insulating materials and non-conductive. Generally, the resistance of insulators decreases with the increase of temperature, but the resistance of floating beads increases with the increase of temperature.
