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.Th頭象有關(guān)，象治平水患成了山石，遠(yuǎn)方的山形就是這五頭象。我試著在高樓間搜尋大象的身影，卻只能在重疊的樓之間看到另一棟樓的皮層。社會(huì)進(jìn)步似乎也只能如此，古老的傳說(shuō)成了路名，成了景觀，原本因遙望而成形的山，現(xiàn)在恐怕只能近觀而無(wú)法知其原意；地區(qū)性豐富的民俗色彩，也只能收集起來(lái)放在邕河對(duì)岸的博物館內(nèi)了。
erefore, 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, hard
