Copper insert temperature resistance, stable performance, can be used for a long time. Different heat preservation materials have different temperature range. Bulk density is small, generally should not be more than 600kg/m3. Bulk density is small, the thermal conductivity is low, and the bracket of the heat insulation pipeline can be reduced.

Copper inserts have certain mechanical strength, can meet the construction requirements, the compressive strength should be greater than or equal to 0.3MPa. Non toxic, non corrosive effect on metals. Fuel and moisture content is very small, easy to process.

Copper block insulation is usually through the equipment or piping in a layer of insulation material, in order to make the insulation material long-term reliable use, also added a layer of protective layer on the outside of the insulation layer.

1 requirements for thermal insulation materials.

Good thermal insulation performance. Coefficient of thermal conductivity is the most important property of thermal insulation materials, as a thermal insulation material, the thermal conductivity coefficient is smaller, the better. Thermal conductivity of thermal insulation material is mainly determined by the size and distribution of air bubbles or air layer, and the relationship between thermal conductivity and thermal insulation material is small.

2 on the protection layer of the requirements, in order to long-term reliable use, outside the insulation layer usually also add a layer of protective layer, the requirements of the protective layer are as follows:

1) good waterproof performance.

2) compressive strength is good, generally not less than 80MPa, not easy to burn.

3) 50 when the thermal conductivity is not more than 0.33W/ (M K).

4) in the case of temperature change or vibration, is not easy to crack or peeling.

5) containing combustible or organic matter is very small, generally should not be more than 10%.
