Xinyang CITIC perlite to meet the
2012-6-4 17:25:36

Xinyang CITIC expanded perlite cryogenic ship a variety of insulation applications range from the low and high temperature applications, insulated concrete require a "super" insulation material, insulation Committee, insulating plaster, stone wall of insulating material and the floor below the Xinyang CITIC lightweight perlite insulating materials.

Xinyang CITIC perlite "super-insulating materials

-150 F (- 101 C) for low temperature applications, and under the requirements of "super" insulation materials, the withdrawal of Xinyang CITIC perlite provides a superior insulation material with thermal conductivity 40 times less than 0.200 Btu.in / h.ft 3F (0.029 W / mK) based on vacuum and temperature. Xinyang CITIC perlite withdrawal of insulating materials usually apply in the double walled helium and hydrogen storage sphere. When the desire of the low thermal conductivity, it may as oxygen, nitrogen and liquefied natural gas storage is also used. In addition to the large areas have been erected storage tanks, the withdrawal of perlite for insulation more small shops to ship a lot of storage design manufacturing cryogenic gas.

Perlite insulation material properties

Xinyang CITIC perlite insulation material for cryogenic service withdrawal on display at the temperature, pressure and density in the range of low thermal conductivity. The normal recommended "place" in the density range is 8 to 9.5 lb/cf3 (128-152 kg.m3).

Cryogenic temperature is usually -150 vacuum Xinyang CITIC perlite thermal conductivity than that is a lot of time below the lower nonevacuated perlite insulation material F.. For example, in the average temperature of -115 F (- 82 C), normal in 4 lb/ft3 (64 kg/m3) unevacuated low temperature perlite will have a thermal conductivity about 22 times as great as the withdrawal of perlite at 8.7 lb / cf3 (139 kg/m3) and 10-micron cell pressure.

In addition to the excellent heat properties Xinyang CITIC perlite, insulation material in the cost is relatively low, easy to handle and install and does not shrink, well, warp or slump. It is not flammable and met the articles of association of the fire, and may reduce insurance costs.

Vacuum service perlite must be dry. Normal moisture limit is 0.1% by weight. Xinyang CITIC perlite moisture greatly increase the necessary pumpdown time to achieve the desired low vacuum. A result, the tankers perlite in moisture-proof bags or sealed must be fresh and packaged. Should not be used Xinyang CITIC perlite request in the paper bag
