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.
【漂珠介紹】

漂珠是一種能浮于水面的粉煤灰空心球，呈灰白色，壁薄中空，顆粒細(xì)、重量輕，高強(qiáng)耐磨、表面封閉而光滑，熱導(dǎo)率小，耐火度高、保溫絕緣、應(yīng)力應(yīng)變均勻等多種功能，廣泛用于耐火、保溫材料的生產(chǎn)和在塑料、涂料、油漆油墨、陶瓷、封裝材料、地板膠、石油鉆探等領(lǐng)域作增強(qiáng)性填充料。能既有效地改善產(chǎn)品性能或施工效果，又明顯地降低生產(chǎn)成本，現(xiàn)已廣泛應(yīng)用于耐火材料的原料之中。

【漂珠特性】

1、高耐火度：漂珠的主要化學(xué)成分為硅、鋁的氧化物，其中二氧化硅（SiO2)約為50-65%，三氧化二鋁(Al2O3)約為25-35%。因?yàn)槎趸瑁⊿iO2)的溶點(diǎn)高達(dá)1725攝氏度，三氧化二鋁(Al2O3)的溶點(diǎn)為2050攝氏度，均為高耐火物質(zhì)。因此，漂珠具有的耐火度，一般達(dá)1600-1700攝氏度，使其成為的耐火材料。
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: choose 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 temper
