1. Definition of insulating glass beads
An insulating glass bead is a sphere consisting of two or more concentric circular glass spherical shells, in which there is a hollow between the inner spherical shell and the outer spherical shell. The diameter of insulating glass beads is generally between 0.2 mm and 2 mm, and its density is light, the breaking strength is high, and it has excellent thermal insulation performance.
Second, the application of insulating glass beads
1. In the field of building materials
As a high-performance building insulation material, insulating glass beads are widely used in wall insulation materials, roof and floor insulation materials, sound insulation materials, dead wall materials, exterior wall coatings and other fields. Among them, the wall insulation material is one of the most widely used fields of insulating glass beads, which is formed by combining insulating glass beads with polymer, silicate and other materials, which has the characteristics of light weight, simple construction and low water absorption.
2. High-tech materials
With their unique physical and chemical properties, insulating glass beads are also widely used in the field of high-tech materials. For example, insulating glass beads can be used to make thermal resistance materials, high-performance ceramic materials, electronic materials, aerospace materials, etc.
3. Characteristics of insulating glass beads
1. Lightweight
The density of insulating glass beads is 0.2-0.5g/cm³, which is about 4-7 times lighter than water and lighter than most building materials.
2. Thermal insulation
Because the hollow glass beads are hollow inside, their thermal conductivity coefficient is low, which can effectively reduce heat conduction, so as to play the role of thermal insulation.
3. Fire prevention
Insulating glass beads have good flame retardant properties and will not burn even at high temperatures, ensuring the safety of buildings in fire.
4. Eco-friendly
Insulating glass beads are non-toxic and harmless, will not cause pollution to the environment and the human body, and are a green and environmentally friendly material.
