How to avoid condensation on the waterproof and breathable membrane

The working principle of waterproof and breathable membrane can be divided into microporous and hydrophilic groups. The former is used for waterproof and 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 through the principle of dispersion. Due to the effect of surface tension, liquid water or water droplets prevent water molecules from passing through, thus avoiding water penetration and making the breathable membrane waterproof. Function.

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

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