The attachment of the outer wall insulation board should begin from the side of the door, window and the walls, etc., gradually move toward the intermediate. The pavement within a section is performed by the downward. The insulation board should be paved with a long-rang...
Slag wool is a kind of white cotton-like mineral fiber that is made of slag as the main raw material and is melted in a melting furnace to obtain a molten material. After further processing, it is a white cotton-like mineral fiber that has the properties of heat preservation and sound insulation....
Today we are going to talk about slag wool. What is it? It is a raw material of mineral fiber board or mineral wool board.
Slag wool or mineral wool made from industrial waste blast furnace slag as the main raw material. Its main components (%) are: SiO2 36~39, Al2O3 10~14, Fe2O3 0.6~1.2, CaO...
Rock wool is the most used thermal insulation material in the cold storage of voyage ships. Its main raw material is basalt. It is a fiber made by high-speed centrifugation after being melted at a high temperature, and a binder, anti-dust oil and silicone oil are evenly added to it. Rock wool is ...
Thermal stress. The thermal expansion and contraction caused by the temperature difference will cause the volume change of the non-structural structure, so that it is always in an unstable state. Therefore, thermal stress is one of the main destructive forces of the external insulation layer of ...
External wall insulation is a method of putting the insulation layer outside the main wall material, which is equivalent to adding protective materials to the entire building, which is the most recommended. So what are the advantages of external wall insulation?
1. Energy saving and good effect

Insulation Materials For Outside Places
In fact, there are many options for outdoor pipeline insulation materials, which can be rubber, glass wool, aluminum silicate, rock wool, etc. The specific one to use depends on the temperature of the equipment and the medium that the pipeline transports. ...
The thermal insulation performance index of the thermal insulation material is determined by the thermal conductivity of the material. The smaller the thermal conductivity, the better the thermal insulation performance. In general, materials with thermal conductivity less than 0.23W/(m·K) are cal...
