What is Glass microsphere?
Glass microsphere (microsphere) is a kind of hollow, closed, spherical, powder-like super-light filling material. Depending on the particle size and wall thickness, the true density is between 0.12 and 0.60 g/cm3, and the particle size is between 15 and 135 um (including various specifications). It has the advantages of light weight, large volume, low thermal conductivity, good dispersibility, fluidity and stability. In addition, it has excellent properties such as insulation, self-lubrication, sound insulation, non-absorption, corrosion resistance, radiation protection and non-toxicity.

Applications of Glass microsphere
After special treatment, glass microspheres have oleophilic and hydrophobic properties, and are easily dispersed in organic materials such as resins. Hollow glass beads have obvious weight reduction, sound insulation and heat preservation effects so that products have good anti-cracking performance and reprocessing performance. They are widely used in composite materials such as glass fibre reinforced plastic, artificial marble and artificial agate, as well as in the fields of the petroleum industry, aerospace, new high-speed trains, automobiles and ships, thermal insulation coatings, etc., and effectively promote the development of science and technology in China.
1. All kinds of retroreflective articles: A metal film perpendicular to the radial direction is placed at the focal point of the spherical lens to reflect the light, and then after passing through the spherical lens, it propagates in the reverse direction of the original incident light to realize the retroreflection of the light.
2. Blowing treatment: Using the characteristics of high hardness, good impact resistance and spherical shape, glass beads can be blown to the sand and protrusions on the casting, and can also be blown to the metal surface for Xing Cai processing.
Characteristics of glass microspheres
1. Excellent optical performance: Glass beads with good optical uniformity inside and on the surface can be made from high-purity glass raw materials, and there is no unevenness on the surface caused by machining. This property can be further improved by proper heat treatment. For example, high-lead or high-peptide barium borosilicate glass can be used to prepare ultra-high refractive index glass beads with a refractive index above 2.0. 2. Characteristics of spherical lens: Glass microbeads have a similar convergence effect to convex lenses, and parallel light passes through the glass microbeads and converges at a point outside the spherical surface. 3. Strong impact resistance: Because the surface of glass beads is spherical, hard and uniform, it has strong impact resistance. 4. Good rolling. 5. Low thermal conductivity: Glass and ceramics have poor thermal conductivity. If glass beads are made hollow, their thermal conductivity will be low. 6. Light hollow glass beads have low density.
Price of Glass microsphere
