Buildings refer to assets made by artificial construction, belonging to the category of fixed assets, including houses and structures. A house is an engineering building for people to live, work, study, produce, operate, entertain, store things, and carry out other social activities. Structures refer to engineering buildings other than houses, such as fences, roads, dams, wells, tunnels, water towers, bridges, and chimneys.
First of all, the amount and intensity of precipitation in humid climates are related to the design of the roof, ground, and underground drainage systems. If the rainwater penetrates into the room through the cracks in the wall, it will cause moisture inside the wall, thus reducing the thermal performance. However, high humidity will make the roofing feel blister, deform, crack, and cause leakage, which will make the wall appear spots, affect the beauty of the wall, and even cause the surface layer to peel off and damage. In addition, if the humidity is too high, the mechanical strength of the material will be significantly reduced, resulting in destructive deformation, and the organic material will also decay, thus reducing its quality and durability. It is easy to breed mold on wet materials. Once the mold is spread to the air and articles, it will endanger people's health and promote the deterioration of articles. So, in a humid environment, moisture-proof design, construction, and decoration are particularly important.
The selection of moisture-proof materials varies from site to site. But most of them are SBS-modified asphalt waterproof coiled materials. The roof is made from polyester tires, PE film covering, and slate covering coiled materials. According to the actual situation of the construction site, the auxiliary materials, such as sealing paste, cold primer oil, etc., should meet industry standards. At the same time, the construction site shall be equipped with an air compressor, spray pressure tank, liquefied gas spray gun, high-pressure hair dryer, trowel, scraper, safety belt, small flat shovel, cement mixer, brush, flame gun, wallpaper knife, rope, roller, and other tools.
Wet building materials: LGR105 movable dehumidifier
If construction is carried out in wet areas, most of the building materials stacked on the construction site will be affected by moisture. Metal and wood products are prone to rust and decay due to moisture. In serious cases, it will lead to material damage and increase construction costs. Although PE plastic products are waterproof to some extent, it is not safe to use plastic products soaked in water for a long time to build houses. In order to keep the building materials dry, we can stack them at a high place where water is not easy to accumulate and cover them with plastic cloth. If conditions permit, the building materials can be stacked in the temporary work shed and dehumidified with a dehumidifier. The Preair LGR105 dehumidifier is energy efficient that can be specially used for the dehumidification of building materials.
Wet structure and concrete: ZETA480 energy efficient dehumidifier
Building structures and concrete will also be affected by moisture and rain. If the humidity of the building structure and concrete is too high, the bearing capacity and firmness of the building will be greatly reduced. The wet structure and concrete are crucial for a building. The drier the air, the harder the concrete, and the stronger the building. A dehumidifier will help a lot. At the construction site in wet areas, the Preair ZETA480 dehumidifier can be equipped for dehumidification. The ZETA480 ceiling hung dehumidifier can quickly reduce the relative humidity of the space within a period of time so that the building structure and concrete will be free from excessive moisture intrusion.
Cold and humid working environment: LGR155 dehumidifier for flood damage
If the construction site is cold and humid, it is recommended to equip LGR155 high-efficient dehumidifier. In order for construction workers to complete their tasks efficiently, it is important to create a dry construction environment as much as possible. If the humidity in the air is too high, the workers cannot expel the sweat from the body when carrying out intensive work, so the sweat has to accumulate on the skin, causing the body temperature to rise continuously, making it sultry. In addition, hazed weather can easily induce cardiovascular diseases. When the air pressure is low and the humidity is high in haze weather, the human body cannot sweat normally, and the probability of inducing heart disease will be higher and higher.
Fluctuation and cracking of hardwood floor: HD90 home dehumidifier
People living in humid areas will find that the hardwood floor will blister irregularly after a period of time if they use the hardwood floor for decoration. The reason is that the humidity is too high. There are two types of floor blistering from the location of blistering: edge blistering and board blistering. The edge blistering is the oval bulge on the edge of the floor board. There are single or multiple blisters in the middle of the two floors, and some are connected, which is irregularly distributed in the room. The board blistering is the oval bulge emerged on the floor surface, which is also irregularly distributed in the room, seriously affecting the beauty and the service life of the floor. Using a home dehumidifier for hardwood floor can effectively control RH, protect the floor from moisture, extend the floor life, and save costs.
Lead, mold and asbestos: PRO500 ceiling mounted dehumidifier
Lead, mold, and asbestos are three "health killers" in the process of building construction and renovation. Asbestos may be contained in various building materials such as floors, insulating materials, and gypsum. Inhalation of asbestos can easily cause asbestosis (lung disease) or cancer. According to the working principle of the dehumidifier, the dehumidifier inhales the wet and dirty air in the room for filtration, evaporation, and condensation. Therefore, particulate matter (lead, mold, asbestos, etc.) in the air will be intercepted by the filter screen, and the gaseous water will be converted into liquid water, which will flow out of the house through the drain. At the same time, the dehumidifier will input fresh air outside the room to complete the air exchange. The dehumidifier works in cycles to achieve the purpose of dehumidification. The use of a PRO500 dehumidifier can effectively filter harmful substances and achieve dehumidification.
