How to avoid condensation on the waterproof breathable membrane

The working principle of waterproof breathable membrane can be divided into two types: microporous and hydrophilic group. The former is used for waterproof breathable membrane. Since the minimum diameter of water droplets is about 20 microns, and the diameter of water vapor molecules is only about 0.0004 microns, the two There is a huge difference in diameter. Water vapor can pass through the microporous membrane by the dispersion principle. Because of the effect of surface tension, liquid water or water droplets make it impossible for water molecules to pass through, which avoids the occurrence of water infiltration and makes the breathable membrane waterproof. Function.

In fact, the installation method of the waterproof and breathable membrane greatly affects the waterproofness of the product and the effect of avoiding condensation! No matter what the water vapor passes through the waterproof and breathable membrane, it needs to pass through the channel and pass through the barrier layer of the building wall. The professional breathable waterproof membrane we produce can scientifically and conveniently allow water vapor to penetrate the past!

When the generated water vapor condenses into water droplets on the building barrier layer, they will drip on the waterproof and breathable membrane, and the waterproof and breathable membrane we installed before has a waterproof effect at this time!
