The principle of moisture resistance of traditional brick and light steel villas

The houses we live in are generally traditional brick-concrete structures. Once they return to the south, the indoor and outdoor humid conditions are obvious to everyone. The waterproof and waterproof capacity of light steel villas is the most concerned issue for many customers when they build houses. Today is the case. Talk to everyone about the moisture-proof principle of traditional brick and light steel villas.

First, what does it mean to return to Nantian?
Back to Nantian is a phenomenon of weather resurgence. It usually occurs in the spring and spring of February and March. It is mainly because the cold air flows quickly and the warm and humid airflow quickly counterattacks, causing the temperature to rise and the air humidity to increase. Some cold objects are exposed to warm and humid air. It is easy to produce water drops.

Second, the main reason for the formation of Nantian
In the spring, the walls and floors of the south sky will be out of water. Due to the cold weather in winter, the walls and floors are cold. If the warm and humid air flows through the walls and the floor, the water in the air will condense into water droplets and attach to the walls and the floor, as if the walls and floors are seeping water. In the summer, even though there is a moist ocean current, the walls and floors are not cold enough, and the walls and floors are still not watery.

Third, the traditional brick-mixed light steel villa's moisture-proof principle
Brick-concrete wall structure: from the outside to the inside, the exterior wall tiles, brick walls, interior wall putty scratching or ceramic tile.
The principle of moisture-proof: The moisture-proof of brick-concrete houses mainly relies on the barrier of water bricks to achieve moisture-proof effect.
At present, most of the brick-and-mortar houses are built with brick walls, using putty for whitening or interior wall tiling. Therefore, when returning to the south, not only indoors are wet, but serious indoors will leave a moldy or interior wall tile. The feeling of wetness.

Wall structure of light steel villa: adopting "two plates and one core wall" from the outside to the inside, the external wall cement hanging board, moisture-proof breathing paper, OSB board, light steel keel, glass wool, OSB board, bamboo fiber board.
The principle of moisture proof: the principle is that the water vapor is in a gas state, the molecular particles are very small, and the microporous membrane can be passed through the diffusion principle to generate a gas permeable phenomenon. The liquid water or water droplets cannot pass due to the surface tension, thereby preventing water penetration from occurring. To waterproof and moisture-proof.
