Flame retardant spunbonded polymer ethylene Basic information of membrane (waterproof and breathable membrane)
one ． one Kedebang waterproof and vapor permeable membrane ( Wind proof waterproof vapor permeable membrane ) It is developed by Nantong Kangda Composite Material Co., Ltd. It is laid on the building envelope Insulation（ heat insulation ) layer
A layer outside Functional membrane For curtain , profiling steel plate , steel ( wood ) Structure, masonry and other composite external walls and pitched roof
temperature ( heat insulation ) The layer coating reduces the penetration of water and air to the building, and at the same time, allows the enclosure structure and indoor moisture to be discharged, effectively avoiding mold and
The letter will doubt the water wall Generated in the roof to ensure thermal insulation ( heat insulation ) The exertion of material efficiency can save energy and improve building durability.
one ． two Kedebang waterproof and vapor permeable membrane is made of recyclable environmental protection materials. The high-density spunbonded cloth and polyethylene are compounded by pressing. It is waterproof and vapor permeable, with high strength, aging resistance, and easy to pave with weight.
Kedebang waterproof breathable membrane is made of high-performance materials, which can allow water vapor to pass through freely, but it can not be penetrated after being condensed into water. This ensures that the building is dry and comfortable, and avoids the condensation of water to damage the roof and wall of the building, as well as damage to indoor items. The working principle of Kedebang waterproof and breathable membrane can be simply described in the left figure: Let me first analyze the cause of condensation. The air contains colorless moisture, which is usually measured by humidity (RH%). The higher the temperature of the air, the more moisture it contains. When the temperature decreases, the air cannot contain the original moisture. The lower the air temperature, the higher the humidity. When the humidity reaches a high standard, the moisture condenses into liquid, and condensation occurs. At this time, the temperature is called condensation point in the building. As long as the hot air in the building volatilizes to contact the roof and wall with lower temperature, Condensation will occur. When condensation occurs, water drops will form on the roof or wall surface, which will be absorbed by the building, thus damaging the wall and roof structure, or dropping, damaging the items in the building. The special waterproof and vapor permeability of the Kodebong waterproof and vapor permeable membrane can not only serve as a waterproof layer, but also solve the moisture-proof problem of the insulation layer. On the one hand, water vapor can pass through and will not accumulate in the insulation layer; On the other hand, dew condensation or water seepage on the roof or wall will be effectively isolated from the thermal insulation material by the waterproof membrane vapor film of the state of Kodak, instead of entering the thermal insulation layer, thus forming an integrated protection for the thermal insulation layer. Ensure the effectiveness of the insulation layer and achieve the role of continuous energy conservation.
