minium (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 (N/cm3)

漂珠用途
1、耐火保温材料：如轻质烧结耐火砖、轻质免烧耐火砖、铸造保温冒口、管道保温外壳、防火保温涂料、保温隔热膏、复合隔热干粉、轻质保温耐磨玻璃钢。
2、建筑材料：建筑装饰、路面铺料、屋顶防水保温涂层、道路工程、改性沥青等。
3、石油工业：油田固井、管道防腐保温、海底油田、漂浮装置、油井钻探泥浆减轻剂、石油天然气输送管道等方面。
4、绝缘材料：塑料活化填充剂、高温高压绝缘体等。
5、涂料工业：油漆、油墨，粘合剂、隐身涂料、绝缘漆、防腐漆、地坪漆、耐高温防火漆、内外墙涂料、保温涂料、地板漆、汽车腻子、原子灰等。
6、航天和空间开发：卫星、火箭、飞船表面复合材料，卫星防火层，海洋设备、船舶、深海潜艇等。
7、塑料工业：如汽车饰件、仪表板、家电外壳、风扇、音箱2 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 s
