漂珠批发 宁波耐火发热冒口漂珠 铸造冒口漂珠30-200目细漂珠现货 低密度轻质耐火漂珠 【漂珠介绍】

漂珠是一种能浮于水面的粉煤灰空心球，呈灰白色，壁薄中空，颗粒细、重量轻，高强耐磨、表面封闭而光滑，热导率小，耐火度高、保温绝缘、应力应变均匀等多种功能，广泛用于耐火、保温材料的生产和在塑料、涂料、油漆油墨、陶瓷、封装材料、地板胶、石油钻探等领域作增强性填充料。能既有效地改善产品性能或施工效果，又明显地降低生产成本，现已广泛应用于耐火材料的原料之中。

【漂珠特性】

1、高耐火度：漂珠的主要化学成分为硅、铝的氧化物，其中二氧化硅（SiO2)约为50-65%，三氧化二铝(Al2O3)约为25-35%。因为二氧化硅（SiO2)的溶点高达1725摄氏度，三氧化二铝(Al2O3)的溶点为2050摄氏度，均为高耐火物质。因此，漂珠具有的耐火度，一般达1600-1700摄氏度，使其成为的耐火材料。
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
3、硬度大、强度高：由于漂珠是以硅铝氧化物矿物相(石英和莫来石)形成的坚硬玻璃体，硬度可达莫氏6-7级，静压强度高达70-140MPa，真密度2.10-2.20g/cm3，因此，漂珠具有很高的强度。一般轻质多孔或中空材料如珍珠岩、沸岩、硅藻土、海浮石、膨胀蛭石等均是硬度差、强度差，用其制的保温隔热制品或轻质耐火制品，都有强度差的缺点。他们的短处恰恰是漂珠的长处，所以漂珠就更有竞争优势，用途更广。corrosion paint, floor paint, high temperature resistant fire retardant paint, exterior paint, insulation paint, floor paint, auto putty, putty, etc.
