The magical application of hollow glass microsphere powder

Overview of hollow glass powder

The hollow glass powder is a micron-level hollow glass microsphere with a smooth surface. The main chemical component is borosilicate glass, which is a hollow transparent sphere under an electron microscope. The hollow glass beads have the characteristics of low density, high strength, high temperature resistance, acid and alkali resistance, low thermal conductivity, electrical insulation, etc., with good fluidity and chemical stability, and are a multi-functional frontier new material across the field.

Hollow glass powder application

Hollow glass balls can be used in marine resource development, aerospace, automotive lightweighting, 5G communications, oil and gas exploration, adhesives, coatings, wood substitutes, rubber, sports equipment, resin grinding wheels, emulsion explosives, artificial stone and other industries. The application of hollow glass powder is to upgrade and optimize the performance of various materials, and is of great significance to the strategy of lightweight and energy-saving materials.

Glass beads are tiny spherical glass used in manufacturing research, medicine, consumer goods and various industries for a variety of purposes. The diameter of glass microspheres is usually between 1 and 1000 microns, but the diameter can range from 100 nanometers to 5 millimeters. Hollow glass microspheres, sometimes called microspheres or glass bubbles, range in diameter from 10 to 300 microns.

Hollow spheres are used as lightweight fillers in composite materials such as synthetic foam and lightweight concrete. The microspheres endow the syntactic foam with light weight, low thermal conductivity and compressive stress far exceeding other foams. These characteristics are used in the hulls of submersibles and deep-sea oil drilling equipment, where other types of foam implode. Hollow spheres of other materials can produce composite foams with different characteristics: ceramic balloons, for example, can produce lightweight composite aluminum foams. Hollow spheres also have applications ranging from storage and slow release of drugs and radiotracers to controlled storage and release research of hydrogen. Microspheres are also used in composite materials to fill polymer resins to achieve specific characteristics such as weight, sandability, and sealing surfaces. For example, in the manufacture of surfboards, the molding machine seals the EPS foam blank with epoxy resin and microspheres to form a water-impermeable and easy-to-sand surface, on which glass fiber laminates are applied.

Glass microspheres can be manufactured by heating tiny droplets of dissolved water glass in a process called Ultrasonic Spray Pyrolysis (USP), and the performance can be slightly improved by using chemical treatment to remove some of the sodium. Sodium consumption also allows hollow glass microspheres to be used in chemically sensitive resin systems, such as long pot life epoxy resins or non-blown polyurethane composites

Additional features, such as silane coating, are usually added to the surface of hollow glass microspheres to increase the matrix/microsphere interface strength (a common failure point when compressed in a tensile manner).

Microspheres made of high-quality optical glass can be used for research in the field of optical resonant cavities or cavities. Glass microspheres are also produced as waste from coal-fired power stations. In this case, the product is usually called "hollow beads" and contains aluminosilicate chemicals (as opposed to the sodium silicate chemicals of engineered spheres). The small amount of silica in the coal is melted, and when they rise to the chimney, they expand and form small hollow spheres. These spheres are collected with the ash, which is pumped into the permanent ash dam through the water mixture. Some particles do not become hollow and sink into the ash dam, while the hollow particles float on the surface of the ash dam. They become annoying, especially when they dry out, because they float in the air and blow towards the surrounding area.
