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.化工填料是填料塔中气液接触的通常零件，在非常多行业都采取普通，具备好的的耐热耐酸效果，能耐除氢氟酸以外的各样无机酸、有机酸及有机溶剂的腐化，可在各种高，低局势采用，其效果的效果是决定填料塔操纵效果的主要缘由。

填料的种类（1）无机填料和有机填料①无机类填料无机类填料主要以天然矿物为原料经过开采、加工打造的颗粒状填料，少数填料是经过处置打造的。a.氧化硅及硅酸盐。b.碳酸盐及碳化物。

c.硫酸盐及硫化物。d.钛酸盐。e.氧化物及氢氧化物。f.金属类。②有机类填料有机类填料由这个天然的动植物及人工合成的有机选材（如再生纤维素、合成树脂等）打造的。（2）惰性填料及活性填料①惰性填料是将天然矿石用湿磨研磨后烘干或干磨成粉直接采用。②活性填料采用偶联剂表面处理使填料表面有被覆层或天然矿物经过煅烧亦或兼有2种诀窍。
3, high hardness, high strength: because of drift beads on silicon aluminum ox
