Copper insert syllable temperature, stable performance, long-term use. Different insulation materials have different use temperature range. Small capacity, generally not more than 600kg/m3. Small capacity, not only low thermal efficiency, but also can reduce the insulation pipe bracket.
Copper inserts have a certain mechanical strength, can meet the requirements of construction, generally its pressure strength should be 0.3MPa. Non-toxic, non-corrosive effect on metals. Combustibles and moisture content is very small, easy to process molding.
Copper insert insulation is usually done by outsourcing a layer of insulation to equipment or pipes, and a protective layer is added to the outside of the insulation layer for long-term reliable use.
1. Requirements for insulation materials.
Good thermal insulation performance. Thermal conductivity is the most important nature of insulation materials, as insulation materials require the smaller the thermal conductivity of the better. Thermal conductivity of insulation materials mainly depends on the size of the air bubbles or air layers contained in them and its distribution status, and the solid properties of the materials that make up the insulation material smaller.
2. The requirements of the protective layer, in order to use for long-term and reliable use, the insulation layer is usually added to the outside of a protective layer, the requirements of the protective layer are as follows:
1) Good waterproof performance.
2) Good pressure strength, generally not less than 80MPa, not easy to burn.
3) The thermal conductivity does not exceed 0.33WW (m?k) at 50 ℃.
4) It is not easy to crack or peel in the case of temperature change or vibration.
5) Contains very few combustibles or organic matter, generally should not be greater than 10% .
