Advantages of sintered clay hollow bricks in modern building applications in brick yard
Sintered blocks have ideal characteristics of absorbing and releasing moisture. It absorbs indoor moisture and releases moisture at the same rate as the block. The surface of the wall can be kept relatively dry in any season, which ensures the comfort of the indoor environment.
The sintered wall roofing material product is a product with a microporous system. Its moisture conduction function can adjust the humidity in the building, and the speed of moisture absorption and drainage is equal. The water absorption and drainage speed of bricks are higher than other building materials 10 The structural strength of the building is not affected in any way when water is absorbed and discharged. This alone can improve the living environment and make the human body feel comfortable. Moreover, the equilibrium moisture content of the brick masonry is very low, which enhances the heat insulation effect of the masonry.
The equilibrium moisture in the wall of a building refers to the balance between the moisture left on the wall after drying and the moisture in the atmosphere. For brick masonry, this equilibrium moisture only accounts for 0.3% to 0.7% of its volume. Compared with other building materials, this is a very low value. It is precisely because of this very low value that it provides a comfortable and healthy environment for people living in brick buildings. The water absorption speed and drainage speed of the brick masonry are almost the same, so it can adjust the humidity of the small environment in the living room, which is often referred to as the “breathing” effect. In addition, the very low equilibrium moisture content of brick masonry is also very important for energy saving.
Because of the increase in water content of building materials, its thermal insulation performance will deteriorate (or deteriorate). In this sense, the brick itself is a very good “insulation body”, and it can also effectively protect the thermal insulation material layer compounded with sintered bricks or blocks, and will not reduce its thermal insulation performance due to moisture absorption. performance. The proper drying time for the main body of a newly-built building means that after the construction of a building in a specific area, it can be dried at an appropriate time without using a special heating method. Generally speaking, each type of masonry structure absorbs water directly from the mortar during construction.
The criterion here is: the speed at which the absorbed water is discharged from the material. Because brick buildings have a slight vapor diffusion resistance, they dry very quickly and the average drying cycle is very short, which provides time for the early delivery and move-in of new buildings. The drying cycle of the wall depends on different regions and seasons. And this drying process of some building materials often lasts for several years.
Therefore, the drying time should be specified in the design according to the selected materials and different regions. Our country is not sufficient for this time, often in order to shorten the delivery period, move in early, resulting in moldy and deterioration of the decorative materials; in addition, due to improper selection of materials, the materials are often dehydrated after the residents move in, causing problems such as wall cracks.
