Floating beads true density tester

Floating beads are a kind of fly ash hollow spheres that can float on the surface of water. They are grayish white and have thin walls. The composition is mainly composed of silica and alumina. It has fine particles, hollow, light weight, high strength and wear resistance. It has many functions such as high temperature resistance, thermal insulation, insulation and flame retardant. It has been widely used in the production of refractory materials, lightweight castables and oil drilling.
In the application of floating beads, density, static pressure strength, floating rate, etc. are important indicators to measure the quality value of floating beads. Due to the special physical properties of floating beads, traditional impregnation can not effectively measure the density of floating beads, most of which use specific gravity. The bottle is tested, but because the material of the floating beads is too light, there are some fine powders in the material. These powders are easily sucked by the vacuum, which affects the test accuracy. To improve the accuracy of the drift bead density test, and to make up for the deficiency of the pycnometer method, Bethes Instrument Technology (Beijing) Co., Ltd. launched 3H-2000TD series real density analyzer, using gas replacement method to accurately measure the density of floating beads;
