Ceiling decoration generally pays attention to three links, first of all, the choice of materials, followed by the keel installation is firm, and finally the seam should be properly left. Let's take a look at the three major aspects of ceiling decoration.
Link 1: Selecting the silicate board is not easy to crack
It is understood that there are three main types of materials for the ceiling of the decoration hall and the roof: water board (also known as splint), gypsum board and silicic acid board. The cost price of the three materials is similar, but the material properties and process requirements are relatively large. The difference is that it is recommended to buy a silicic acid board that is not easy to crack when purchasing ceiling materials.
The water splint is lighter in weight and less difficult to construct, but the board is susceptible to moisture. The gypsum ceiling also has the disadvantage of being easily damp. In comparison, the quality of the newly introduced silicic acid board is relatively guaranteed, but the material is heavier and the process difficulty is relatively large, which is time consuming and laborious.
Session 2: The keel is installed firmly
When installing the keel, the arrangement of the explosion screws should not exceed 1 meter, otherwise there will be potential safety hazards. It is recommended to use a light steel keel as the frame. The so-called light steel keel is actually a plated iron plate, which is better than wood.
In addition to strong safety, the keel hoisting is flat, which will directly affect the visual effect of the ceiling. Therefore, the installation process must also pay attention.
Link 3: Reserve the seam to prevent deformation and cracking
When fixing the ceiling on the keel, a slot-integrated ceiling is reserved between the board and the board to prevent the ceiling from being cracked. The seam is about 5~8 mm, and it is usually 8 mm. If there is no keel at the seam, the multi-dimensional dragon industry decoration is recommended to put a board on the inside and stick it, then apply the ash at the seam, and it looks seamless from the outside.
A name for Silicon Carbide.
It is produced from quartz sand and high quality anthracite under high
temperature in an electric resistance furnace.If looks black and has a
microhardness of 2800-3300kg\mm2,being used for produce the abrasive tools.It
is also fit for process the grind metals and non-metals material of low tensile strength,such as grey cast iron,brass,aluminium ,stone,leather
and hard rubber ect.Also can be used as refractory materials and in electronic
industry.
