Floating bead is a kind of hollow fly ash ball that can float on the surface of water. It is grayish white, thin and hollow. The composition is mainly silica and aluminum oxide. It has fine particles, hollow, light weight, high strength, wear resistance, Various functions such as high temperature resistance, thermal insulation, and flame retardant insulation have been widely used in the production of refractory materials, lightweight castables, and oil drilling. In the application of bleaching beads, density, static pressure strength, floating rate, etc. are important indicators to measure the quality value of bleaching beads. Due to the special physical properties of bleaching beads, the traditional impregnation cannot effectively measure the density of bleaching beads, and most of them use specific gravity The bottle is tested, but due to the light weight of the floating beads, there are often some fine powders in the material. These powders are easily sucked back by vacuum, which affects the test accuracy. To improve the accuracy of the density test of the floating beads, to make up for the shortcomings of the specific gravity bottle method. Instrument Technology (Beijing) Co., Ltd. launched the 3H-2000TD series true density analyzer, using the gas replacement method to accurately measure the density of floating beads; Clothing Display Rack,Fashion Clothing Display Stand,Kid Clothes Display Stand,Wooden Clothing Hanger Rack Dongguan Display Leader Co., Ltd , https://www.displayonestop.com
