南充耐火漂珠 鑄造發(fā)熱冒口漂珠 40-200目空心細漂珠報價 保溫涂料漂珠 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
【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(zhì)。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(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(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、強度差，用其制的保溫隔熱制品或輕質(zhì)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(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rick, 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.
