The internal insulation of the external wall is a construction method in which the insulation layer is added to the interior of the external wall structure to make the building reach the heat preservation and energy savi...
The thermal insulation properties of PMI foam insulation materials have always been very good, especially at room temperature, its thermal insulation performance is much better than other insulation boards. In addition, ...
Due to the PMI foam board as the core material, the case of color steel movable house fires has increased dramatically. For fire safety, fire tests were conducted on color steel plates. PMI foam sandwich panels and rock ...
In the process of plastic molding, when a certain gas is added or some foaming agent is added, a large amount of air bubbles can be generated, so that the volume of the plastic suddenly expands several times or even seve...
The thermal conductivity of ordinary plastic products is mostly in the range of 0.15 ~ 0.22W / (m, K), while the thermal conductivity of foam plastics is generally in the range of 0.01 ~ 0.04W / (mK), 15 ~ lower than ord...
The chemical principles of core foams can be divided into two categories: Chemical blowing agents are used which liberate gases when heated. Commonly used chemical blowing agents, such as azodicarbonamide, azobisisobutyr...
