Embodiment Construction

[0015] The composite reflective thermal insulation, damping, vibration and noise reduction board and its manufacturing process of the present invention have passed industrial production tests.

[0016] Baotou Iron and Steel (Group) Co., Ltd. Steel Plant 90 tons of molten steel tank, tundish

[0017] From October 2001 to the present, 27 molten steel tanks have been installed with 5 mm thick composite reflective heat insulation, damping, vibration and noise reduction panels. After testing, the results showed that the temperature of the outer wall of the molten steel tank dropped by 42°C, the temperature drop rate of the molten steel dropped by 0.82°C / min, the electrode radiation noise was reduced by 11dB during smelting in the LF furnace, and the service life was as high as 18 tanks. There is 1 room bag. After testing, the results showed that the temperature of the outer wall of the tundish dropped by 83°C and the temperature of the molten steel increased by 12°C.

Abstract

A reflecting, heat-insulating, vibration-damping and noise-reducing composite plate is made up from nanometre latex, metal foil, fibre cloth and fibre yarn through multi-layer combination, continuous coating and rolling. Its advantages are heat insulating effect increased by 2-3 times, high compressive strength increased by 10 times, high damping ratio up to 30% and reducing LF noise by over 10 dB.

Description

technical field [0001] The invention relates to a composite reflective thermal insulation, damping, vibration and noise reduction board and a manufacturing process thereof, belonging to new energy-saving and environment-friendly materials and new processes. Background technique [0002] The existing technology of low temperature insulation and cold preservation is described in Xu Lie et al.'s "Low Temperature Insulation and Storage and Transportation Technology" (Mechanical Industry Press, 1999, P70-72) and Su Zhenqin and Lu Yanjing's "A New Type of High Efficiency Multilayer In the paper "Development of Thermal Insulation System (Gs-80 Multilayer Thermal Insulation System)" (Journal of Space Science, Volume 2, Issue 3), Jinke's invention patent "Composite Thermal Aluminum film and spacer are composited, and aluminum foil and spacer are also composited. Among them, the spacers are mainly made of glass fiber cloth, glass fiber paper, nylon mesh, plant fiber paper, carbon-fil...
