堆积情况也被改进。漂珠的宽的粒径分布使得小的微球能够填充到大的微球之间的空隙中。其结果……实际上就是：高加入量、高固体含量、较低的VOC和减少其它成份的用量；
2.低粘度/改善流动性：与不规则形状的颗粒不同，漂珠很容易在彼此

漂珠特性
1.具有活性高、质轻;
2.绝热、电绝缘性好;
3.耐高低温、耐腐蚀、防辐射、隔音;
4.耐磨、抗压强度高;
之间滚动。这使得使用漂珠的体系具有较低的粘度，较好的流动性。而且，体系的可喷涂性也得到改善；
3.硬度/耐磨性：漂珠是一种强度高，而且坚硬的微球，它能增强涂料的硬度、耐洗刷性能和耐磨性；
4.优良的隔热效果：由于漂珠中空的球体结构，使得的其填充于涂料中具有优良的ace amounts of the gas (N2 and H2 and CO2, etc.), heat transfer is very slow.So drift beads not only light (250-450 kg/m3 density), excellent heat preservation and heat 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 is 2.10 2.20 g/cm3, therefore, drift beads with high strength.
4, insulated non-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&＃39;t have other insulating materials.So, it is can make excellent insulation.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.
Drift beads use
1, refractory insulation materials;Such as light sintered brick, light unburned brick, 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.
2, construction materials;Building decoration, high-grade pavement materials, roof waterproof thermal insulation coating, road engineering, modified asphalt, etc隔热效果；
5.光泽控制：作为一种填料所起的作用，漂珠能降低光泽，用来控制汹涌，甚至在加入量要求较高的情况下，它们也能消除象普通的消光剂容易造成的粘度的大幅度增加，而且成本也低；
6.惰性：漂珠由惰性成份组成，因而具有优良的经久耐用性、耐侯性、耐腐蚀性和抗化学性能；
7.不透明性：漂珠的空心的球形使光线慢射和散射，其结果是增加了涂料的遮盖力；
8.分散性：漂珠分散同矿物填料一样，由于漂珠的厚壁和很高的抗压强度，它能承受所有种类的搅拌机、挤压机及模塑机的加工过程；
9.无结晶硅污染：与其它的填料不同，漂珠中结晶硅的含量在无危害的水平以下。此类漂珠不被看作致癌物质，也不需要特别的危害警告标志注明。
