The ceilings that we usually see are finished products. Do you know what is the process of ceiling ceilings? Good ceilings must have excellent materials to ensure that the ceiling of the ceiling will not be deformed for a long time. This article will give you an understanding of the process and construction methods of ceiling ceilings, and learn more about these benefits for home decoration ceilings. Ceiling ceiling craft At present, the main materials used for home-use ceilings are paper plasterboard and plywood. Light steel keels, wooden squares, and caulking materials are also suitable. Any problem with any one of these materials may lead to cracking of the entire structure. Deformation. Gypsum plasterboard is a cladding material for ceilings and partitions. Be careful not to use overboards and wet boards. Overfire plate refers to the gypsum board in the drying process, the temperature is too high or time is too long to make the gypsum board core dihydrate gypsum dehydration and lose strength, so that the gypsum board is easy to break and can not hold the self-tapping screws; wet board is not enough drying The water content of the gypsum board is too large, and the water is volatilized and deformed after the gypsum board is arranged on the keel. These two inferior gypsum boards are often encountered in low-priced gypsum boards produced on small, semi-manufactured production lines. The selection of plywood as cladding material for ceilings and partitions must also focus on quality requirements. The caulking materials include seam strips and caulking putties. The seam strips must have a certain strength and act as stiffeners at the seams of the panels. Caulking putty must not only have good strength, adhesion, but also have a certain degree of toughness and good construction performance, if it does not meet the requirements will produce cracks in the board seam. Home decoration generally uses kraft paper as a seam tape, using putty as a caulking filler. Ceiling construction method The correct construction method is the guarantee that the ceiling does not crack. The construction process is also very important, especially for the practice of some special-shaped parts, it must be carefully designed, carefully calculated, elaborately constructed, and the construction method should be used flexibly. 1. Light-gauge steel keels can be used as much as possible with wood keels and light steel keels. This is because the increase and decrease of wood is relatively large and it easily leads to structural deformation. 2. Pay attention to expansion joints during design and construction. Each joint should be left with expansion joints, and inverted into a 45-degree angle, so as not to accumulate stress. 3. Light steel keel or wooden keel installation smooth, spacing specification. 4. The self-tapping screws should be evenly distributed to ensure that the force applied by each self-tapping screw is close. Otherwise, it is easy to form a side-lock reaction to make the structure lose its stability and cause deformation cracks. Improper environment is another cause of cracking in ceiling deformation. Humidity is the most important environmental factor affecting the cracking deformation of plasterboard and plywood. During the construction process, there are moisture from all aspects, so that the plate absorbs the surrounding moisture, and in the long-term use, it gradually dry and shrink, resulting in cracking plate cracks. Therefore, during construction, air humidity should be reduced as much as possible and good ventilation should be maintained. Construction should be carried out until the water content of the concrete reaches the standard. Minimize wet work. When surface treatment is performed, appropriate sealing measures can be taken on the surface of the sheet, such as rolling the varnish once more to reduce the moisture absorption of the sheet. Cracking of the ceiling is the most common quality problem in the home improvement process. With so much to say, it is still impossible to completely avoid the problem of ceiling cracking. If there is cracking in your home ceiling, please don't panic and inform the decoration company about the warranty. Generally after a four-year round of tests, the home improvement will stabilize and the cracking of the ceiling will not occur.
