Glass wool, also known as glass fiber insulation, is an artificial inorganic fiber material widely used in various industries due to its excellent thermal insulation, sound absorption, and fire resistance properties.
Production Process
Glass wool is primarily made from natural minerals such as quartz sand, limestone, dolomite, along with chemical raw materials like soda ash and borax. These materials are melted at high temperatures to form a glass-like liquid. The liquid is then spun into fine fibers through centrifugal force or blowing processes, creating a fluffy, cotton-like material. To enhance its shape stability and durability, thermosetting resins or other binders are added and cured under heat and pressure, forming various shapes and specifications such as boards, pipes, and blankets.
Unique Properties
Glass wool stands out for its low density, low thermal conductivity, and high resilience. It is an excellent sound absorber, effectively reducing noise pollution in various environments. Moreover, its fire resistance is commendable, making it a safe choice for applications where fire prevention is crucial. The material is also resistant to aging and has no adverse effects on the health environment.
Diverse Applications
Due to its versatile properties, glass wool is utilized in numerous industries. In the power, petroleum, chemical, and light industry sectors, it serves as insulation for equipment and pipelines, enhancing energy efficiency. In the construction industry, glass wool products like blankets and boards are used for wall and roof insulation, contributing to better thermal comfort and energy savings. Additionally, its excellent sound absorption capabilities make it ideal for use in acoustic systems, transportation vehicles, and home appliances, providing a quieter living and working environment.
