Drift beads characteristics
1, high refractoriness, the main chemical compositions for silicon drift beads, aluminum oxide, silica (SiO2) about 50-65%, 3 oxidation 2 aluminium (Al2O3) about 25-35%.Because the melting point of silica (SiO2) is as high as 1725 degrees Celsius, 3 oxidation 2 aluminium (Al2O3), the melting point of 2050 degrees Celsius, are all high refractory material.Therefore, drift beads have high refractoriness, generally 1600-1600 degrees Celsius, make its excellent high performance refractories.
2, light, heat preservation and heat insulation: drift beads thin wall hollow, empty cavity for half a vacuum, only trace amounts of the gas (N2 and H2 and CO2, etc.), heat transfer is very slow.So drift beads not only light (250-450 kg/m3 density), excellent heat preservation and heat insulation and thermal conductivity at room temperature (0.08-0.1), which play a prominent role in the field of lightweight thermal insulation material for its laid a solid foundation.
3, high hardness, high strength: because of drift beads on silicon aluminum oxide mineral phases (quartz and mullite) formation of hard vitreous, hardness of Morse 6-7, hydrostatic strength up to 70-140 mpa, true density of 2.10 2.20 g/cm3, therefore, drift beads with high strength.General light porous or insulating materials such as boiling rocks, diatomite, perlite, sea pumice, expanded vermiculite is the difference in hardness, strength is poor, with its system of thermal insulation products or light refractory products, intensity difference flaws.The advantages of their shortcomings is drift beads, so drift beads have more competitive advantages, used more wid
