The key to solving the problem of sound after floor covering is to solve people's stepping on the floor and ensure that the floor does not move up and down.

1. uneven ground
Due to the unevenness of the ground, after the floor is paved, gaps are created between the floor and the ground in individual places. During the walk, the floor moves up and down, producing a sound. Its characteristic is that after the floor is paved, people will immediately make noises when they walk around, and they are partial.
Take measures to measure the flatness of the ground before the floor is laid. The flatness should be less than 3mm/2000mm. If the ground does not meet the requirements, it should be leveled before paving.
2. In the case of floor paving, the clearance reserved around the floor is insufficient. Insufficient reserved space around the floor paving leads to slight arching of the floor. There is a gap between the floor and the ground, and the sound is generated when people walk around. Its characteristic is that it does not ring after being paved. After a period of time, it buzzes over a large area, and the wall and floor are very tight. Take measures to leave gaps around the floor, especially in the entrance, wall kitchen, balconies and other areas to leave gaps to ensure that the reserved gap is uniform. When the pavement length exceeds 8m, it should be cut off and bridged.
3. After the damp-proof membrane is laid on the floor, the moisture-proof membrane joint is not sealed with tape, and the moisture-proof film in some places is broken during the pavement process, causing leakage of moisture on the ground, especially in the geothermal environment, the ground is damp, and a lot of moisture enters. The back of the floor, causing uneven expansion, causes the floor to be deformed, slightly twisted, and a gap between the floor and the floor creates a sound during the pedaling process. The characteristic of this type is that there is no sound after just paving, and after a period of time there is a large area of ​​sound, and there may be gaps between the wall and the floor. Take measures before the floor pavement, moisture-proof membrane joints must be sealed with tape to ensure airtight.
4. Symmetrical placement of indoor furniture (heavy objects) After laying on the floor, the furniture and the heavier items are placed symmetrically on both sides of the room, the floor is pressed, and in the humid environment, the floor absorbs moisture and expands. Both sides are held down by heavy objects and the floor cannot be shaken, creating a regional bulge. Causes floor noise in the area. Take measures to place heavy objects on one side as much as possible to ensure free movement on one side of the floor.
The sound of the floor is sometimes the result of a factor, and sometimes it is the result of a combination of several factors. Therefore, in order to prevent floor noise from occurring after paving, comprehensive measures and comprehensive prevention should be taken.

Flap discs are made by Aluminum oxide,calcined aluminum, SIC or zirconia coated cloth, also call as power flex discs. Flap discs have the advantages of grinding discs and fiber discs, making it easier for grinding and polishing disposable, reducing the work process and lower the grinding cost.
Abrasive grains include: Aluminum oxide, calcined aluminum, silicon carbide and zirconia.
Flap discs are widely used in grinding and polishing of wood, glass, stainless steel, futniture, mold, metal casting, weld seams and so on. Especially, zirconia power-flex discs fit in sanding seld seam of stainless steel. Flap discs have the features of quick speed, high efficiency, synchronous consumption, strong grinding force, fast heat disspation and good performance.
