熔点(℃)漂珠是一种能浮于水面的粉煤灰空心球，呈灰白色，壁薄中空，颗粒细、重量轻，高强耐磨、表面封闭而光滑，热导率小，耐火度高、保温绝缘、应力应变均匀等多种功能，广泛用于耐火、保温材料的生产和在塑料、涂料、油漆油墨、陶瓷、封装材料、地板胶、石油钻探等领域作增强性填充料。能既有效地改善产品性能或施工效果，又明显地降低生产成本，现已广泛应用于耐火材料的原料之中。

【漂珠特性】

1、高耐火度：漂珠的主要化学成分为硅、铝的氧化物，其中二氧化硅（SiO2)约为50-65%，三氧化二铝(Al2O3)约为25-35%。因为二氧化硅（SiO2)的溶点高达1725摄氏度，三氧化二铝(Al2O3)的溶点为2050摄氏度，均为高耐火物质。因此，漂珠具有的耐火度，一般达1600-1700摄氏度，使其成为的耐火材料。

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250-450kg/m3)，而且保温隔热(

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 widely.
4, excellent electrical insulation, non-conductive: choo有的现实社区范围，由互联网构建了一个更为庞大的“虚拟社区”，整合提供更多的养老资源信息，也因此被称为没有围墙的养老se after degaussing beads drift beads, is the performance of insulation materials, conductive.Insulation resistance are commonly by the rise of temperature, drift beads, on the other hand, increases with the increase of temperature resistance.This advantage is don't have other insulating materials.So, it can make is performance under the condition of high temperature insulation products.
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, other lightweight insulation materials generally large particle size (e.g., perlite, etc.), if the grinding would significantly increase capacity, insulating the stays is reduced greatly.
