rials.So, it is can make excellent insulation.5, particle size, specific surface area;Drift beads natural formation of the particle size of 1-250 microns.Specific surface area of 300-360 - g/cm2, and cement.Therefore, drift beads without grinding, can be used directly.Fineness can meet the needs of a variety of products.
Drift beads use
1, refractory insulation materials;Such as light sintered brick, light unburned brick, casting insulation riser, pipe insulation shell heat preservation and heat insulation, fire insulation paint, paste, composite insulation dry powder, light resistant glass fiber reinforced plastic.700度,使其成为优异的高性能耐火材料。 质轻、保温隔热。漂珠壁薄中空,空腔内为半真空,只有极微量的气体(N2、H2及CO2等),热传导极慢极微。所以漂珠不但质轻(容重250-450公斤/m3),而且保温隔热优异(导热系数常温0.08-0.1),这为其在轻质保温隔热材料领域大显身手奠定了基础。 硬度大、强度高。由于漂珠是以硅铝氧化物矿物相(石英和莫来石)形成的坚硬玻璃体,硬度可达莫氏6-7级,静压强度高达70-140MPa,真密度2.10-2.20克/cm3,和岩石相当。因此,漂珠具有很高的强度。一般轻质多孔或中空材料如珍珠岩、沸岩、硅藻土、海浮石、膨胀蛭石等均是硬度差、强度差,用其制的保温隔热制品或轻质耐火制品,都有强度差的缺点。他们的短处恰恰是漂珠的长处,所以漂珠就更有竞争优势,用途更广。粒度细,比表面积大。漂珠自然形成的粒度为1-250微米。比表面积300-360cm2/g,和水泥差不多。因此,漂珠不需粉磨,可直接使用。细度可满足各种制品的需要,其他轻质保温材料一般粒度都很大(如珍珠岩等),如果粉磨就会大幅度增加容量,使隔热性大大降低。在这方面,漂珠有优势。电绝缘性优异。选去磁珠后的漂珠,是性能优异的绝缘材料,不导电。一般绝缘体的电阻均随温度的升高而降低,漂珠

耐火度;漂珠的主要化学成分为硅、铝的氧化物,其中二氧化硅约为50-65%,三氧化二铝约为25-35%。因为二氧化硅的溶点高达摄氏1725度,三氧化二铝的溶点为摄氏2050度,均为高耐火物质。因此,漂珠具有极高的耐火度,一般达摄氏1600-1700度,使其成为优异的高性能耐火材料。
2、 质轻、保温隔热;漂珠壁薄中空,空腔内为半真空,只有极微量的气体(N2、H2及CO2等),热传导极慢极微。所以漂珠不但质轻(容重250-450公斤/m3),而且保温隔热优异(导热系数常温0.08-0.1),这为其在轻质保温隔热材料领域大显身手奠定了基础。
3、硬度大、强度高;由于漂珠是以硅铝氧化物矿物相(石英和莫来石)形成的坚硬玻璃体,硬度可达莫氏6-7级,静压强度高达70-140MPa,真密度2.10-2.20克/cm3,因此,漂珠具有很高的强度。
4、绝缘不导电;一般绝缘体的电阻均随温度的升高而降低,漂珠则相反,随温度的升高电阻增大。这一优点是其他绝缘材料都不具备的。所以,它可以制作是性能优异的绝缘材料。5、粒度细,比表面积大;漂珠自然形成的粒度为1-250微米。比表面积300-360g/cm2,和水泥差不多。因此,漂珠不需粉磨,可直接使用。细度可满足各种制品的需要。
