新余耐火保溫漂珠 鑄造冒口漂珠 20-100目低密度高鋁含量漂珠價格 灰白色漂珠的作用 【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、重量輕，高強耐磨、表面封閉而光滑，熱導率小，耐火度高、保溫絕緣、應力應變均勻等多種功能，廣泛用于耐火、保溫材料的生產和在塑料、涂料、油漆油墨、陶瓷、封裝材料、地板膠、石油鉆探等領域作增強性填充料。能既有效地改善產品性能或施工效果，又明顯地降低生產成本，現已廣泛應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%。因為二氧化硅（SiO2)的溶點高達1725攝氏度，三氧化二鋁(Al2O3)的溶點為2050攝氏度，均為高耐火物質。因此，漂珠具有的耐火度，一般達1600-1700攝氏度，使其成為的耐火材料。

2、質輕、保溫隔熱：漂珠壁薄中空，空腔內為半真空，只有極微量的氣體(N2、H2及CO2等)，熱傳導極慢極微。所以漂珠不但質輕(容重250-450kg/m3)，而且保溫隔熱(導熱系數常溫0.08-0.1)，這為其在輕質保溫隔熱材料領域大顯身手奠定了基礎為的那么愛，希望她能夠找到更愛她的人。

答：有個成語叫：成家立業。即，在舊社會，男人。

3、硬度大、強度高：由于漂珠是以硅鋁氧化物礦物相(石英和莫來石)形成的堅硬玻璃體，硬度可達莫氏6-7級，靜壓強度高達70-140MPa，真密度2.10-2.20g/cm3，因此，漂珠具有很高的強度。一般輕質多孔或中空材料如珍珠巖、沸巖、硅藻土、海浮石、膨脹蛭石等均是硬度差、強度差，用其制的保溫隔熱制品或輕質耐火制品，都有強度差的缺點。他們的短處恰恰是漂珠的長處，所以漂珠就更有競爭優勢，用途更廣。

4、電絕緣性，不導電：選去磁珠后的漂珠，是性能的絕緣材料，不導電。一般絕緣體的電阻均隨溫度的升高而降低，漂珠則相反，隨溫度的升高電阻增大。這一優點是其他絕緣材料都不具備的。所以，它可以制作是性能的高溫條件下的絕緣材料制品。

5、粒度細，比表面積大：漂珠自然形成的粒度為1-250微米。比表面積300-360g/cm2，和水泥差不多。因此，漂珠不需粉磨，可直接使用。細度可滿足各種制品的需要，其他輕質保溫材料一般粒度都很大(如珍珠巖等)，如果粉磨就會大幅度增加容量，使隔熱性大大降低。

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: 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 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.
drift beads use
1, fire-resistant 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.
