The board gap is too large due to the dry and shrinking of the floor. The analysis of quality is caused by improper control of the moisture content of the product itself. In addition, the ground is not flat, the lock is not well combined, and the sizing is uneven, which is also likely to cause such problems.
1. Slot type:
There are several common cases of common seams: triangular seams at the ends of the floor, triangular seams at the ends and sides, or gaps on the sides, and irregular distribution in the room.
2. Causes:
(1) One-side expansion caused by ventilation at the joint of moisture-proof membrane
When the laminate flooring is installed, the joint of the moisture-proof film is not adhered by the waterproof tape, one side of the floor is above the moisture-proof film, and the other side is at the joint of the moisture-proof film. Since the joint of the moisture-proof film is not adhered with the waterproof tape, the moisture intrusion causes the side of the floor to become longer, and the lengths of the two long sides of the floor are different, so that the end of the floor has a triangular seam. The characteristics of this situation are:
a) There is no triangular seam after the floor is installed, which occurs after a period of use;
b) the water content on both sides of the floor strip is inconsistent, generally differing by more than 2%;
c) After the floor is disassembled, it can be seen that the moisture-proof film is not adhered to with waterproof tape.
Such problems occupy a considerable proportion of complaints in the floor triangle gap. The moisture-proof film must be adhered with waterproof tape to ensure that it is airtight and can avoid problems.
(2) Installation quality problems
In the floor installation, due to the uneven force during installation, the floor has a triangular gap, and the direction of the arrow is tightened to eliminate the gap between the triangle and the side. The characteristics of this type of problem are:
There is a triangular seam after the floor is installed;
b) there is a gap on the side of the floor;
After the floor is disassembled, the moisture-proof film has been adhered with waterproof tape;
d) the triangular gap and the side gap can be eliminated after the floor is tightened;
e) The ground is not flat, with the foot on the floor, the floor flutters up and down, feeling very uncomfortable, accompanied by a squeaking sound.
(3) Improper humidity control Sina Leju 5e"E"l
When the living room is unoccupied for a long time, if the humidity in the room is not adjusted in time, the floor shrinkage may cause seaming or arching.
