Glass wool is a kind of insulation material with dolomite and quartz sand as raw materials.  

 

Glass, degradation time on the earth almost nearly a hundred years, a large number of glass products produced by human wandering in the soil, mountains, rivers and rivers.  If it can't be recycled in human factories, the damage to the natural environment is irreversible.  Fortunately, asbestos insulation materials because of carcinogenic side effects have been banned, glass wool gradually replaced the original asbestos market.  

 

So can glass wool really keep heat?  

 

Glass wool is made from natural rock and can also be recycled glass.  Through the high-end automatic glass sorting device, glass recycling materials smaller than 2cm can be identified.  After a series of cleaning and forging processes, the glass wool raw material is fused with catalytic combustion assisted slag in a furnace of up to 1360 degrees Celsius.  The fiberglass spun out of the centrifuge is already 50 percent of the original form of fiberglass.  

Fiberglass insulation comes from these seemingly unremarkable fiberglass fibers.  

 

Glass fiber diameter in 4-6 microns.  Interlacing of fibers creates gaps that lock temperature molecules in glass wool.  Back-and-forth thermal radiation rebound emission is less, but also a large probability of thermal insulation device for temperature stability.  The state of glass fiber is also the key to the insulation effect: the glass fiber is even and slender, overlapping process, can be closely fitted, when using, glass fiber will not be because of tension or folding, thickness of different state.  In the state of uniform thickness, can effectively for all kinds of thermal insulation targets for a long time and maintain the machine work.  

  

In different directions of use, different glass wool products are used. Glass wool pipe and glass wool felt are commonly used for pipe insulation.  Glass wool board and glass wool felt are commonly used in HVAC.  In addition to its insulation, it has a bonus: it absorbs sound.  Therefore, the use of glass wool insulation at the same time, but also can absorb the noise generated in the middle.  Attenuation of sound energy transmission.
