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 - 灼失率(%)

【漂珠用途】
1、耐火保溫材料:如輕質(zhì)燒結(jié)耐火磚、輕質(zhì)免燒耐火磚、鑄造保溫冒口、管道保溫外殼、防火保溫涂料、保溫隔熱膏、復(fù)合隔熱干粉、輕質(zhì)保溫耐磨玻璃鋼。
2、建筑材料:建筑裝飾、路面鋪料、屋頂防水保溫涂層、道路工程、改性瀝青等。
3、石油工業(yè):油田固井、管道防腐保溫、海底油田、漂浮裝置、油井鉆探泥漿減輕劑、石油天然氣輸送管道等方面。
4、絕緣材料:塑料活化填充劑、高溫高壓絕緣體等。
5、涂料工業(yè):油漆、油墨,粘合劑、隱身涂料、絕緣漆、防腐漆、地坪漆、耐高溫防火漆、內(nèi)外墻涂料、保溫涂料、地板漆、汽車膩?zhàn)?、原子灰等?br />
6、航天和空間開發(fā):衛(wèi)星、火箭、飛船表面復(fù)合材料,衛(wèi)星防火層,海洋設(shè)備、船舶、深海潛艇等。
7、塑料工業(yè):如汽車飾件、儀表板、家電外殼、風(fēng)扇、音箱、燈具總承、鑄件、齒輪、結(jié)構(gòu)件、拉鏈、管材、板材等。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.), i
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,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處,所以漂珠就更有競爭優(yōu)勢,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。
