Product Application
Let's first analyze the causes of condensation. The air contains colorless moisture, which is usually measured by humidity (RH%). The higher the temperature of the air, the more water vapor it contains. When the temperature decreases, the air cannot contain the original water vapor. The lower the air temperature, the higher the humidity. When the humidity reaches 100%, the water vapor condenses into liquid and condensation occurs. The temperature at this time is called condensation point. In the building, as long as the hot air in the building volatilizes and contacts the roof-free and wall with lower temperature, condensation will occur. The temperature at this time is called condensation point in the building. As long as the hot air in the building volatilizes and contacts the roof and wall with lower temperature, condensation will occur. When condensation occurs, water droplets will form on the roof or wall surface. The water droplets will be absorbed by the building, thus damaging the wall and roof structure, or dripping and damaging the articles in the building, the use of Medabo waterproof breathable membrane waterproof vapor permeability, in addition to the role of waterproof layer, but also to solve the problem of moisture insulation layer.
On the one hand, water vapor can pass through and will not gather in the thermal insulation layer; On the other hand, the roof or wall condensation or water seepage will be effectively isolated from the thermal insulation material by Medabao waterproof breathable membrane, and will not enter the thermal insulation layer, thus protecting the thermal insulation layer, ensuring the effect of the thermal insulation layer and achieving the effect of continuous energy saving.
The air tightness, water tightness and vapor permeability of the enclosure system are closely related to the energy saving, durability and comfort of the building.
Practice has proved that no matter what kind of laying form, it is difficult to ensure the sealing of the enclosure system. The cracking of fine stone concrete is difficult to avoid, and the overlapping of profiled steel plates and tiles is difficult to be tight. Through these non-closed pores, airflow and water vapor can invade the enclosure system, which has a serious impact on the energy saving, durability and comfort of the building.
1. Energy saving of buildings
◆ Rainwater and water vapor intrusion into the building envelope system will reduce the effective thermal resistance of the insulation layer
◆Airflow invades the building envelope system to form convection circulation, which will also reduce the performance of the insulation layer
◆ Increase the heating equipment to ensure that the indoor temperature is appropriate, thereby increasing the building energy consumption.
2. Durability of the building
◆ Rainwater and water vapor invade the building envelope system and erode building materials,
Accelerate the aging of building materials, thereby affecting the durability of the building.
3. Building comfort
The intrusion of airflow adversely affects the indoor thermal comfort.
◆ Pollutants and radiation enter the room through the airflow, thus affecting the indoor air quality.
The water vapor entering the building envelope is sealed in the structure for a long time, which leads to the generation of moisture and the formation of mold, thus reducing the comfort of living.
4. Dewing phenomenon
◆Because the higher the air temperature, the more water vapor it can contain, that is, the higher the saturation temperature; on the contrary, the lower the air temperature, the lower the saturation temperature. When the air temperature drops and is lower than the saturation temperature, the water vapor will be in the state of water droplets. Condensation and separation from the air, which leads to condensation.
◆ When water vapor accumulates and condenses in the insulation layer, it will reduce the thermal efficiency of the insulation layer and cause moisture vapor problems such as mildew on the inner side of the outer wall. Due to the temperature difference between indoor and outdoor
Therefore, condensation is difficult to avoid.
Due to the sealing characteristics of traditional waterproofing membrane (such as asphalt waterproofing membrane, etc.), the water vapor can not be discharged freely, which leads to the formation of mold.
◆ Therefore, it is essential to ensure the permeability of the building and to achieve natural drying in the form of water vapor diffusion to the outside.
To sum up, the energy saving, durability and comfort of the building are closely related to the air tightness, water tightness and vapor permeability of the enclosure system, and the waterproof breathable membrane enclosure system is through the improvement of the above factors to achieve the purpose of building energy saving, durability and comfort of the living environment.
Advantages of Medbao waterproof breathable membrane
High temperature resistance-the use of working temperature of 250 ℃.
Low temperature resistance-has good mechanical toughness; even if the temperature drops to -196 ℃, it can maintain 5% elongation.
Corrosion resistance-for most chemicals and solvents, showing inert, strong acid and alkali, water and various organic solvents.
Weather-resistant-there is an aging life in plastics.
High lubrication-is the low coefficient of friction in solid materials.
No adhesion-is the small surface tension in a solid material and does not adhere to any substance.
Non-toxic-physiologically inert, as a long-term implantation of artificial blood vessels and organs without adverse reactions.
Widely used in steel structure workshop, opera house, airport terminal, library, gymnasium, large exhibition center, wood structure house, light steel villa, all kinds of dry hanging material roof curtain wall, etc.
