| 4.1. Thermal insulation envelope structure
|
Outer wall material: 1.2m double-sided electrolytic plate, surface spraying
Inner wall material: 1.0 rust steel plate SUS304 Box insulation material: foaming material Door insulation material: foaming material Vertical temperature zone (high temperature chamber, low temperature chamber) temperature shock chamber arranged vertically up and down, the sample is placed in the carrying basket and connected together by the screw rod and the sample basket) to move between the high temperature chamber and the cryogenic chamber. The box is an integral structure (non-assembled plate structure), and the outer wall is sprayed cold-rolled steel plate. The wall of the studio is SUS304 high-quality stainless steel plate, smooth and flat, the thermal insulation material is stress-resistant insulation material, and the inner wall of the unit part has sound absorption and noise reduction measures. |
