First, the advantages and disadvantages of gypsum board
Advantages:
1, dry operation, safety, convenient and quick construction, combination as required, flexible space division and convenient demolition. It can effectively save labor and speed up the construction progress.
2, the decorative effect is good. Various shapes, convenient decoration and wide use. The surface layer of gypsum board partition wall can be compatible with a variety of surface decoration materials, meet the decoration requirements of most buildings, and can generally be used in offices and conference rooms.
3, the expansion rate is small. The chemical and physical properties are stable, and the expansion rate is small in the process of drying and moisture absorption, which effectively overcomes the defect that other light boards in China crack due to large expansion and contraction during use. And because of its own structure, it is easy to set deformation joints, so it can be used in parts where slight displacement or slight vibration is easy to occur.
4. Less waste. Compared with the common brick-concrete secondary structure wall, it has the advantages of avoiding gouging caused by water and electricity pre-embedding, avoiding plastering and leveling caused by surface decoration, and even omitting plastering of gypsum and putty in wallpaper decoration surface operation, thus reducing construction cost, shortening construction period, saving resources and avoiding waste.
Disadvantages:
Gypsum products are white and fine in texture. When solidified, they will not shrink in volume like lime and cement, but expand (the expansion amount is about 1%).
Second, how to fix the gypsum board on the wall
1. Before the formal construction, measure whether the chalk line of the wall shell is horizontal with a horizontal tube. Only by ensuring the true level of the foundation line, the suspended ceiling installed in the later period will not tilt and there will be no height difference.
2. Gypsum board ceiling needs to be fixed on a solid wooden keel frame, so carefully selecting keel materials has become an essential step before. I suggest that you try to choose pine material with better nail grip. Because the keel is made of wood, we must pay attention to fire prevention. The standard practice is to brush the fire retardant coating evenly on the keel surface, and then nail it on the wall after the whole keel turns white, so as to ensure that the contact with the wall surface is also brushed with fire retardant coating.
3. The keel surface can be assembled after fire prevention treatment, and the joint of the two keels is fixed at an angle of 45 with a nail gun. At this time, it is necessary to master the strength to prevent the keel from cracking.
4. Finally, the gypsum board is formally installed. It is best to use stainless steel drywall nails to fix gypsum board. Such nails will not rust, and gypsum boards will be beautiful for a long time to come.
After the above introduction, do you all know the advantages and disadvantages of gypsum board? Gypsum board will need to be fixed when decorating. I hope the above methods can help everyone.
