Dampness and mildew know how much?

Damp and mildew in the basement

Humidity and mildew are the biggest problems plaguing the use of the basement function, mildew is caused by a variety of different molds, although mold is a microorganism, but the growth environment still needs water and nutrients, in a suitable environment, mold is inevitable.

The conditions required for mold growth and metabolism are relatively broad.

Mold growth temperature, humidity and pH range is very wide, the most suitable growth temperature is 25~35℃, the relative humidity is higher than 75%, the pH value is generally between 1.5~11, the optimal pH value is about 6.0.

The nutritional requirements of mold growth and metabolism are the same as other microorganisms, which are water, carbon source, nitrogen source, inorganic salt, vitamin and so on. Its nutritional sources include starch, oil, protein, fiber, etc., but also includes water, inorganic salts and so on.

Therefore, the conditions that cause mildew in the basement are:

1, the basement decoration materials inside and on the surface have enough nutrients of mold, wood products, cloth and other most used decoration materials.

2. The moisture needed by mold is the moisture in the basement

There are three sources of moisture:

1, the structure (ground, wall and top surface) wet, this kind of moisture is mainly structural leakage or moisture itself, in the full sunken basement accounted for 60-70%,

2, the air is humid, accounting for about 20-30%,

3, life moisture (such as breathing, sweating, drying, cooking, mopping, etc.), accounting for about 10%.

To stop mildew, only by cutting off the supply of water and nutrients that supply mold, moderate dryness is most easily achieved in a basement environment

How to stop dampness and mildew

Traditional measures are overhead layer and partition wall construction, multi-layer internal and external waterproof, decorative materials as far as possible with stone, glass, tile, integrated board and other materials not afraid of water, these measures from so many years of experience are not ideal and thorough. Preventing structural moisture priority to ensure that the structure is rigid and self-waterproof, the concrete impermeability grade is enough, the construction vibration is sufficient, the demolition time is good, the maintenance is good, etc., can ensure that the structure does not appear open water leakage, other building materials masonry structure needs full mortar, surface painting quality assurance, these are the basis, On this basis, the installation of an electroosmotic pulse (electroosmotic) impermeable dehumidification system can ensure that the structure is dry. To ensure that the air is dry, you need to install air dehumidification equipment. The common market is mobile dehumidifier, central dehumidification system and air conditioning dehumidification, etc. Here, you need to match the dehumidification amount of equipment with the space. If the interior structure surface decoration material is a breathable material, it is more conducive to the electroosmotic system to play the function of reducing air humidity. If the construction of the basement is decorated in the humid and hot season, the moldy materials are best treated first, and 1-2 sets of high-power industrial mobile dehumidifier are equipped during the basement decoration to reduce the air humidity and prevent mold while decorating

We focus on accurate long-term design:

No longer the pursuit of the "big" venue of cool extravagance, people-oriented re-start, more attentively in order to make you more relaxed.

Build a self-drying system for the main structure of the house to create a more comfortable and livable indoor and underground space.

There is no doubt that a technology has been invented is great, but it is still too weak to compete for this point of enthusiasm.

Relying on the fear of noise gradually, pushed to the thorn land, is the controversy is not big enough.

When the spotlight is focused, it begins to increase the chance of "being accepted".

The iteration of technology is the wisdom of scientists,

But for the story line to be more coherent, it needs a public awareness awakening.
