- After the fusion of a mixture of natural sand and recycled glass at 1,450 °C, the glass that is produced is converted into fibres. The cohesion and mechanical strength of the product is obtained by the presence of a binder that “cements” the fibres together. Ideally, a drop of bonder is placed at each fibre intersection. This fiber mat is then heated to around 200 °C to polymerize the resin and is calendered to give it strength and st
ability. The final stage involves cutting the wool and packing it in rolls or panels under very high pressure before palletizing the finished product in order to facilitate transport and storage. Glass wool having better advantages compair to other insulation materials.But it is hazardous due to its
duct & very small glass particles which can travel into the human body during inhalation. web:http://www.glass-wool-insulation-china.com
USE
- Glass wool is a thermal insulation that consists of intertwined and flexible glass fibres, which causes it to "package" air, resulting in a low density that can be varied through compression and binder content. It can be a loose fill material, blown into attics, or, together with an active binder sprayed on the underside of structures, sheets and panels that can be used to insulate flat surfaces such as cavity wall insulation, ceiling tiles, curtain walls as well as ducting. It is also used to insulate piping and for soundproofing.
