Gypsum board is a commonly used building material in the decoration of suspended ceilings and interior wall partitions in houses. Its quality directly affects the effectiveness of the decoration of suspended ceilings and interior wall partitions.
Gypsum board is a material made mainly from building gypsum, and is one of the new lightweight boards that are currently being developed with great emphasis. A good gypsum board must have waterproof, moisture-proof, fireproof, high-strength, stable, and thermal insulation properties. So before purchasing gypsum boards, it is important to look and compare them more, and buy high-quality gypsum boards in order to use them with peace of mind.
How to choose gypsum board can be referred to from the following aspects.
1. Product logo
When selecting gypsum boards, it is important to purchase regular gypsum boards. Formal gypsum boards will be clearly labeled on the packaging box with product name, trademark, quality level, manufacturer name, production date, and other symbols and fonts.
So when choosing gypsum boards, it is important to identify major brands. The quality of gypsum boards from major brands is excellent, which can ensure the normal progress of the project.
2. Dimensional deviation
When purchasing gypsum board, it is important to pay attention to the size, and the deviation in size should meet the product qualification standards. If the size deviation is small, the quality of gypsum board will be better; The size deviation is large, and there may be uneven joints during the later installation of gypsum boards.
3. Appearance performance
When selecting gypsum boards, it is necessary to find a place with sufficient light and visually inspect the surface of the board. A good gypsum board surface should be flat and smooth, without pores, stains, cracks, missing corners, uneven colors, and incomplete patterns. The side of the gypsum board cannot be ignored either. A good gypsum board has a dense texture and no hollowing, and the denser the gypsum board, the more durable it is.
4. Uniform texture
When selecting gypsum boards, it is important to pay attention to whether the texture of the board is uniform. We can distinguish it by listening to the sound. If the sound produced by tapping the gypsum board with your hand is very strong and low, it indicates that the texture of the gypsum board is very uniform and tight; If the sound emitted by the gypsum board is particularly spacious, it indicates that there is hollowing phenomenon inside the gypsum board, and the texture is not compact and uniform, resulting in poor quality. At the same time, this method can also effectively identify the elasticity issues of gypsum boards.
5. Flatness and right angle deviation
Check if the flatness and right angle deviation of the gypsum board meet the qualified standards. Good quality gypsum boards have very small flatness and right angle deviation. If the flatness and right angle deviation are large, the finished surface of the gypsum board will become uneven in the later stage, and poor quality of the gypsum board may also occur.
