The product is expanded from selected special particle size mineral sand under electric furnace heating, with controlled temperature and residence time of raw materials to achieve surface fusion and sealed pores, forming irregular spherical granules with a porous cavity structure inside. The surface is vitrified and sealed with a smooth luster, and the physical and chemical properties are highly stable. This product can serve as a lightweight aggregate in the new building materials industry; as a partial substitute for polystyrene beads in the lightweight refractory material industry; and as a substitute for glass microspheres in the industry, with broad application prospects. It can be widely used in various fields such as industry, agriculture, building materials, chemicals, smelting, and light industry.
Borosilicate microsphere function:
1. Suitable for thermal insulation of interior and exterior walls of reinforced concrete, aerated concrete blocks, porous bricks, and fly ash bricks, etc.
2. Suitable for roof insulation layer.
3. Also suitable for energy-saving retrofitting of old buildings.
4. Suitable for fireproof and thermal insulation projects in basements, garages, fire lanes, grain warehouses, stairwells, factory buildings, and more.
5. The product can serve as a partial substitute for lightweight aggregates in the new building materials industry, for expanded glass beads in the lightweight refractory material industry, and as a replacement for glass microspheres in the emulsion industry.
6. In the chemical industry, utilize glass microspheres as a densifying regulator. Widely applicable in various fields such as industry, agriculture, building materials, chemicals, metallurgy, and light industry.

Glass microspheres inorganic thermal insulation mortar is a new type of green inorganic material, featuring excellent sound absorption, breathability, high temperature and frost resistance, low shrinkage rate, seamless structure, and no formation of cold or heat bridges.

Application Range:
