Insulation material characteristics

Insulation materials are getting more and more fire, so what are the characteristics of insulation materials?

The insulation of industrial equipment and pipelines, the use of thermal insulation measures and data aerogels were first used in spacesuit insulation fabrics developed by NASA. It has the characteristics of low thermal conductivity, low density, high flexibility, fireproof and waterproof. Its normal temperature thermal conductivity is 0.018W/(K·m) and it is definitely waterproof. The heat preservation function is 3~8 times of traditional data. The heat insulating fabric has the characteristics of low thermal conductivity, low density, high flexibility, fireproof and waterproof.

Light weight, usually 10-96kg/m3, 20kg/m3 is felt, 24-48kg/m3 is medium hard, 48-96kg/m3 is hard board, 48kg/m3 can be used as ceiling, softening point is 500°C Arranged, insulated at 300 ° C, the United States uses a larger amount, k = 0.9. The calcium silicate insulation product has been successfully developed in the 1970s. It has high compressive strength, small thermal conductivity, convenient construction and reusable features. It is widely used in power systems.

Most of the domestic production is generally small workshops. Later, four production lines have been introduced from the United States. The technology is advanced, instant-speed quick-forming fiber-forming, dry-needle felt, stable quality, and can withstand temperatures of 800-1250 °C. Features: Acidity derivative of 2.0 or more, high temperature resistance, usually more than 1000 °C chemical pipeline, this information must be used. The temperature of the solution is at 2000 °C.

The main products are polystyrene foam and polyurethane foam, but there are doubts about the use of the construction category. Mostly used for wire mesh sandwich panels, color steel composite sandwich panels, although there are certain constraints, but the development is faster, with the construction of fire protection on the data requirements are becoming more stringent, the use of this data presents a new topic.
Insulation data can collect excess heat, when the smooth release, the gradient change is small, useful to reduce the loss, room temperature can be, winter insulation can play a balancing effect. In the renovation of the new building and the renovation of the old building, it overcomes the disadvantages of wall cracks, condensation, mold, and peeling; and it is safe and reliable to bond with the whole substrate, with good randomness, no cavity, and prevention of negative wind pressure tearing. Dropped. It is useful to overcome the doubts such as the ribs on the back of the sheet splicing and the falling angle of the outer corner of the horn. The organic matter in the data and the free acid reaction in the base of the main wall constitute a compound, enter the micropores of the main wall, form a community, ensure dry adhesion, and improve the wet adhesion retention rate, and have excellent adhesion. The original materials such as floating beads and brucite fibers (tubular fibers) are selected, and the closed hydrophobic microporous cavity structure is formed in the structure, and as a phase change data carrier, the phase change data can be ensured for a long time.
