绵阳30目*珠报价多少钱 低密度灰白色*珠

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/****流动性：与不规则形状的颗粒不同，*珠很容易在彼此之间滚动。这使得使用*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****；  
      3.硬度/*性：*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*性；  
      4.优良的隔热效果：由于*珠中空的球体结构，使得的其填充于涂料中具有优良的隔热效果；  
      5.光泽控制：作为一种填料所起的作用，*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：*珠由惰性成份组成，因而具有优良的经久*性、耐侯性、耐腐蚀性和*化学性能；  
      7.不透明性：*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：*珠分散同矿物填料一样，由于*珠的厚壁和很高的*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，*珠中结晶硅的含量在无危害的水平以下。此类*珠不被看作致癌物质，也不需要特别的危害警告标志注明。   t high performance refractories.
2, light, heat preservation and heat insulation: drift beads thin wall hollow, empty c*ity for half*acuum, only trace 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 promine*ole in the field of lightweight thermal insulation material for its laid a solid foundation.
3, high hardness, high strength: because of drift beads*ilicon 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, di*ite, 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 h*e 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 h*e 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 formati
    10.高固体工业涂料：低粘度、高加入量，减少VOC，改进硬度，控制光泽，增加*性、可喷涂性，降低成本； 
    11.水溶性工业面漆：增加固体含量，降低薄膜渗透性，增进耐腐蚀性、硬度、惰性、*性，控制光泽，降低成本；  
    12.隔热、保温、防火涂料：耐高温、阻燃、隔热效果优良；
