What is dew point of thermal insulation material?
The heat insulation lining has the characteristics of low thermal conductivity, small density, high flexibility, fire prevention, waterproof, etc..Light weight, 10 96kg/m3, 20kg/m3 following mat, 24 48kg/m3 as in hard, 48 96kg/m3 as core, which 48kg/m can fand a softening point of the ceiling, 500 degrees C, 300 degrees C insulation, the larger the amount, k=0.9.Calcium silicate insulation product was successfully developed in 70s. It has the characteristics of high compressive strength, small thermal conductivity, convenient construction and repeated use. It has been widely used in power systems.Most of the domestic universal small workshop production, have been imported from the United States after the four production lines, advanced technology, instant rejection speed fiber, dry needle felt, stable quality, high temperature 800 to 1250 DEG C.Features: acidity derivative of more than 2, high temperature resistant, general chemical pipe 1000 degrees C more, must use this material. The temperature is about 2000 C.
Insulation materials, insulation for industrial equipment and piping, thermal insulation measures and material aerogels were first applied to the space suit thermal insulation linings developed by nasa. With low thermal conductivity, small density, high flexibility, fire, waterproof and other characteristics. Its temperature coefficient of thermal conductivity 0.018W/ (K = m) and absolute waterproof, insulation performance is 3~8 times of traditional materials.
Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.
