杭州耐火漂珠 耐高溫 低密度 高鋁含量漂珠價(jià)格 40-200目灰白色漂珠成本多少錢 【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。

2、質(zhì)輕、保溫隔熱：漂珠壁薄中空，空腔內(nèi)為半真空，只有極微量的氣體(N2、H2及CO2等)，熱傳導(dǎo)極慢極微。所以漂珠不但質(zhì)輕(容重250-450kg/m3)，而且保溫隔熱(導(dǎo)熱系數(shù)常溫0.08-0.1)，這為其在輕質(zhì)保溫隔熱材料領(lǐng)域大顯身手奠定了基礎(chǔ)。

3、硬度大、強(qiáng)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(jiān)硬玻璃體，硬度可達(dá)莫氏6-7級(jí)，靜壓強(qiáng)度高達(dá)70-140MPa，真密度2.10-2.20g/cm3，因此，漂珠具有很高的強(qiáng)度。一般輕質(zhì)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(qiáng)度差，用其制的保溫隔熱制品或輕質(zhì)耐火制品，都有強(qiáng)度差的缺點(diǎn)。他們的短處恰恰是漂珠的長(zhǎng)處，所以漂珠就更有競(jìng)爭(zhēng)優(yōu)勢(shì)，用途更廣。

4、電絕緣性，不導(dǎo)電：選去磁珠后的漂珠，是性能的絕緣材料，不導(dǎo)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(yōu)點(diǎn)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(xì)，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(xì)度可滿足各種制品的需要，其他輕質(zhì)保溫材料一般粒度都很大(如珍珠巖等)，如果粉磨就會(huì)大幅度增加容量，使隔熱性大大降低。

n 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
