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。
2、质轻、保温隔热:漂珠壁薄中空,空腔内为半真空,只有极微量的气体(N2、H2及CO2等),热传导极慢极微。所以漂珠不但质轻(容重250-450kg/m3),而且保温隔热(导热系数常温0.08-0.1),这为其在轻质保温隔热材料领域大显身手奠定了基础。
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c处理中效果好的是针对于带正电荷的悬浮粒子、较粗、浓and gas pipelines, etc.

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 th
化工厂的污水类型也有很多种,不同产品所产出的污水差异也很大,所以即使有污水处理的经验,但也很难具体说出要用哪种处理剂效果明显。而对于这种现象有效且直接的方法就是多做些测试,对比看哪种效果较好些。生产步骤多产出的废料多、废水多。污水也很难处理,相对于造纸厂污水和生活污水来说,化工厂的污水处理难度较大,这样的污水比较复杂。
现在的污水处理市场较为混乱,而对于顾客来说,在选购产品时,要多对比价格。而安家净在此向您承诺,我们的产品质量好,价格优惠,后期的服务也很到位,值得您前来了解。对于阴离子聚丙烯
