glass wool insulation cheap * for sale for building
1.Excellent thermal insulation performance under both high,mid and low temperature.It can hold up to 400℃.
2.Fireproof. Not produce harmful gas.
3.High rebound rate.
4.Excellent soundproof performance.
5.Low moisture absorption rate even under humid environment.
6.Anti aging,long service life.
7.Very low slag inclusion content.
Glasswool is made mainly of quartz s, dolomite, feldspar and limestone, calcined soda, borax recycled glasses. The raw materials are stored in silos, weighed, mixed and poured into the furnace.
2. Glasswool melting
The melting of the mix is obtained at a temperature above 1400℃ in an electrical furnace.
3.TEL fiberizing, binder
Through a feeder, the glass flows to the fiberizing machine. When flowing so, the glass reaches the required temperature to be converted into fibres.Glass wool is made from fibreglass, which is layered and arranged to produce a similar texture to that of wool. The way it’s made is a bit like the way fairy floss is spun; molten liquid glass made from sand and recycled glass products is pulled through a superfine mesh by centrifugal force, and the tiny strands dry and cool on contact with air. The individual fibres are held together with a binding agent, which helps to hold glass wool together and give it strength.
4. Forming, curing
The products impregnated with resins are then taken to a curing oven heated at 250°C. The hot air flows through the glasswool blanket and, while curing the fibres, gives a correct rigidity. The binder becomes yellow.
At the exit of the curing oven, circular saws or high pressure water jets split the blanket according to its trade width. the final presentation varies from rools to slabs, according to the end-use application. Off-cuts are also recycled into the production process.
6. Packaging, delivery
Packed in either rolls or panels (also called ‘batts’) for transport.The end of the line is generally equipped with a rooling machine for mats and a stacking machine for boards.Then delivery by trucks or containers.
