Glass wool is produced by mixing glass with various additives in a specific ratio, then melting the mixture in a glass furnace. The molten solution is then passed through a sieve and into a centrifuge. Under the high-speed rotation of a centrifugal machine, the glass is spun into fine streams, which are further stretched into fibers by the action of a high-temperature, high-speed flame. After applying an atomized binder, the fibers coated with resin binder settle on a moving cotton net belt under the vacuum wind, forming a uniform cotton felt. The felt is then cured in an isothermal curing oven to complete the solidification process, shape the product, and after shaping, it is cut to the predetermined size before being packaged.
Rockwool products are a new type of lightweight insulation material, made primarily from refined basalt. After being melted at high temperatures and processed into inorganic fibers by high-speed centrifugal equipment, they are mixed with a special binder and dust oil. The fibers are then laid on a conveyor belt and structured through a specialized device to alter their arrangement. Finally, they are cured and shaped into various products, such as rockwool boards, rockwool felt, and rockwool tube shells, depending on their intended use.
Two: Different Product Performance
Glass wool has lower bulk density, fewer slag balls, a lower thermal conductivity, a longer service life, and greater fiber toughness compared to rock wool. However, rock wool can be used at temperatures around 600 degrees Celsius, while glass wool is only suitable for temperatures around 260 degrees Celsius.
Section Three: Diverse Product Applications
Glass wool is generally used for insulation in areas below 200 degrees Celsius, commonly for general buildings or low-temperature pipelines. Rock wool is typically used for insulation in areas with temperatures up to 500 degrees Celsius, often for high-temperature thermal pipelines or electrical equipment.
