Waterproof retaining layer for basement retaining wall
Dligence XPS extruded insulation board
We board is based on material and extruded polystyrene resin and other polymer, by heating mixed with catalyst, high density hard foam board and plastic extrusion molding and manufacturing, referred to as (XPS). This unique closed cell cellular structure to support plate has a rather low water absorption (almost no absorption), low thermal conductivity, high compressive strength, ageing resistance (normal use almost no aging decomposition phenomenon).
Dligence XPS extruded insulation panels product features:
1, excellent insulation performance
With high thermal resistance and low linear expansion ratio, the characteristics of the low, the obturator structure rate reached more than 99%, the formation of a vacuum layer, avoid air flow cooling, to ensure that the insulation performance of lasting and stable, relative to the closed cell foam polyurethane rate of 80%, the leading advantage is self-evident. Practice has proved that the insulation effect of 20mm thick XPS extruded insulation board is equivalent to that of 50mm thick foamed polystyrene and 120mm thick cement perlite. Therefore, this material is currently the best choice for building insulation.
2, excellent high strength compressive resistance
Because of the special structure of XPS board, its high compressive strength, impact resistance is strong, according to different sizes and thickness of XPS its compressive strength reached 150 ~ 500Kpa above the ground, can withstand the load of each system, widely used in Geothermal Engineering, highway, airport runway, square ground, large cold storage and refrigerated trucks etc..
3, high quality hydrophobic and moistureproof
Water absorption is an important parameter to measure thermal insulation materials. The thermal insulation properties of the insulating material decrease after water absorption. At low temperature, the water absorbed easily freezes, and destroys the structure of the thermal insulation material, thus reducing the compressive and heat insulation performance of the board. Due to the fact that the molecular structure of polystyrene does not absorb water, the molecular structure of the plate is stable and the gap is free, and the problems of leakage, permeation, frosting and condensation of other materials are solved.
4, light texture, easy to use
The complete closed cell type chemical structure of the XPS plate and the physical structure of the honeycomb shape have the characteristics of light weight and high strength, which is convenient for cutting and transportation, and is not easy to be damaged and convenient to install.
5, stability, good corrosion resistance
The use of the long time, aging, decomposition, does not produce harmful substances, the chemical property is very stable, not as a result of corrosion due to water absorption and degradation, the performance decline, still can maintain its superior performance in high temperature environment, according to the relevant data, XPS extruded insulation board even using 30 ~ 40 years, can still maintain excellent performance, and does not decompose or mildew, no toxic substances volatile.
6, product environmental performance
XPS board by the relevant departments of the state testing, chemical stability, non volatile harmful substances, harmless to the human body, the production of raw materials using environmentally friendly materials, without producing any industrial pollution. The product is environmentally friendly building materials.
