Applying coatings on expanded perlite particles to seal the surfaces thereof is not per se unique to the present invention. U.S. Pat. No. 3,769,065 discloses a process of coating expanded in a prior separate operation by applying an aqueous acid solution to the particles, then applying an aqueous sodium silicate solution followed by another acid …
Vacuum super insulation (VSI) with expanded perlite powder is commonly used at cryogenic temperatures, but principally can also be adapted to applications at higher temperatures, such as the long-term storage of hot water in solar thermal systems. Due to the lack of experimental data in the respective temperature range, especially without …
The greatest advantage of using expanded perlite aggregate in cultured (manufactured) stone and brick veneer products is the weight savings—as much as a third the weight over typical mix designs. ...

Expanded perlite is pressurized with nitrogen in a tank truck and drawn into the annular space by a combination of vacuum and ...
Transportation and storage expenses are higher because expanded perlite is voluminous. There is a double expenditure for handling and storage of the materials, first for the raw material and then for the expanded perlite. For these reasons, bulk handling is usually a more expensive method of servicing a job than using a portable furnace. 4 ...
Perlite is an insulation board composed of inorganic expanded silicaceous volcanic glass (perlite) combined with organic fibers and binders. Air cells within the expanded perlite provide its insulating efficiency. The top surface of the insulation board is treated with either an asphalt coating or a proprietary coating.

expanded perlite was compacted into a 10" pipe to a density of 90-110 kg m-3 to simulate typical design scenarios for larger vacuum insulated vessels. To measure the permeation of both liquid and gas through the perlitree, a series of thermocouples were placed within the column of perlite and any gas that did permeate was collected and measured.
