Do you know the characteristics of hollow glass beads? Let me introduce it to you today.
1. Acid resistance. Silicon dioxide and alumina are the main components of hollow glass beads, which make them stable in a variety of solvents, acids and weak bases.
2. Can be used as filling material. Hollow ball is 2-50 microns in diameter, excellent flow of hollow ball.
3. Electrical insulation. The insulation makes it suitable as a filling material for various electrical switchgear.
4. Low thermal conductivity. Hollow glass beads are excellent fillers for making thermal insulation coatings and mortars. They are suitable for use in thermal and sound insulation equipment.
5. The price is low. The hollow glass bead has small volume density, less use than other filling materials, low weight load of polymer, and low production cost.
6. The contraction rate is low. The hollow glass bead has low shrinkage, which can meet the needs of low shrinkage filling materials industry. Especially in the field of large-scale filling and polymers.
7. High intensity. The shell of hollow glass bead is hard and can bear high compressive strength.
8. Low oil absorption. Compared with calcium carbonate, hollow glass beads have lower oil absorption, which can reduce the viscosity of the resin system and help reduce costs.
9. Flame retardant. As a kind of inorganic metal oxide, the melting point of hollow glass microsphere is more than 1450 ℃, and it will not decompose even at high temperature, and it is not easy to deform. Can improve the flame retardancy of polymers, often used in building materials and coatings industry.
