Hollow glass microspheres are a new type of materials with wide applications and excellent properties developed in recent years. The main component of this product is borosilicate, which has a particle size of 10-250 microns and a wall thickness of 1-2 microns. The product has the advantages of light weight, low thermal conductivity, high strength and good chemical stability. After special treatment, it has oil-affinity and hydrophobicity, and is easily dispersed in organic materials such as resins. Hollow glass microspheres are widely used in glass fiber reinforced plastics, artificial marble, artificial agate and other composite materials. They have obvious effects of weight reduction and sound insulation, so that the products have good crack resistance and reprocessing performance. It has been widely used in aviation, aerospace, new high-speed train, luxury yacht, thermal insulation paint, bowling and other fields, and has played a unique and good role.
Hollow glass beads (hollow glass beads) are small, hollow spherical powders. The particle size can be chosen arbitrarily between 30-100 microns and the density is 0.1-0.7g/ml. It has the advantages of light weight, large volume, low thermal conductivity, high compressive strength, good dispersion, fluidity and stability. In addition, it also has excellent properties of insulation, self-lubrication, sound insulation, non-water absorption, fire resistance, corrosion resistance, radiation protection, non-toxicity and so on. This product can be directly filled in most types of thermosetting and thermoplastic resin products, play a role in reducing product weight, reducing costs, eliminating internal stress to ensure dimensional stability, high compression resistance, impact resistance, fire resistance, sound insulation, insulation, etc. Some expensive fillers such as bronze powder, molybdenum dioxide and silica can also be banned.
Hollow glass beads are made of inorganic materials. According to the chemical composition, there are silica, alumina, zirconia, magnesium oxide, sodium silicate and so on. Its particle size ranges from 10 to several hundred microns, and it is a closed micro sphere filled with CO2 gas. It has the advantages of light weight, low thermal conductivity, non-toxicity, non-flammability, good chemical stability and high dispersion. It is an excellent product filler for artificial marble, fiberglass reinforced plastics, atomic ash, paint, plastics, explosives, chemical industry, building materials and other industries.
