In the refrigerator production, the shell needs to use heat insulation and cold insulation layer, the latest heat insulation material nano aerogel insulation felt can not only heat insulation and cold insulation, but also sound absorption and noise reduction, in March this year, le Wang industrial bought a batch of nano aerogel insulation felt from our company, after use found four characteristics:
● energy saving: 10 % - 30 % energy saving. Compare with other heat preservation materials, that pow saving is about 0.1 degrees per day.
● sound absorption and noise reduction: ceramic fiber can reduce high-frequency noise with frequency less than 1000 Hz. for sound waves with frequency less than 300 Hz, the sound insulation capability is superior to that of common sound insulation materials, and noise pollution can be significantly reduced.
● space saving: increase effective volume by 20 % - 30 %. By adopting the nano composite heat insulation board hlgx - 864, the cold preservation is guaranteed, the cold preservation wall is thinner, and the space is saved; compared with the house price of tens of thousands of yuan per flat, the space is saved.
● fire protection is safer: the composite insulation board can resist temperature up to 1000 ℃.
