After the summer, the rainfall in the north has gradually increased, and the humidity of the air has increased. The complaints of multi-layer solid wood composite flooring and lacquered lock composite flooring (MDF as the base material) are also increasing.What caused it?
Analysis of the causes of the edges chipping of multi-layer solid wood composite flooring:
1. The ground is uneven
Due to the uneven ground, after the floor is paved, there is a gap between the floor and the ground in some places. When people are walking, the floor moves up and down, and the sides between the floors rub against each other to cause chipping. Its characteristic is that after the floor is paved, the edge collapse occurs in the area where people often walk, and it is local. The measure to be taken is to measure the flatness of the ground before paving the floor, and the flatness should be less than 3mm/2000mm. Grounds that do not meet the requirements should be leveled before paving.
2. The moisture-proof membrane is breathable
After the floor is paved, because the joints of the moisture-proof film are not sealed with tape, the moisture-proof film in some places is damaged during the paving process, causing moisture leakage on the ground, and a large amount of moisture enters the back of the floor. Slight distortion creates a gap between the floor and the ground in a local area. When people are walking, the floor moves up and down, and the sides of the floor rub against each other to cause edge collapse. Its characteristic is that there may be gaps between the wall and the floor. The measure to be taken is to seal the joints of the moisture-proof membrane with tape to ensure airtightness before paving the floor.
3. Hidden dangers in product production
After the multi-layer solid wood composite floor is tenoned, in the process of roller coating or drenching, the paint spills to the grooves of the floor. The actual width of the paint film is greater than the width of the surface layer of the floor, which causes hidden dangers of floor chipping and paint spillage. The more, the greater the chance of the floor chipping. For the production process of first tenoning and then painting, paint spillage is inevitable. Although it cannot be judged as a quality problem according to the corresponding product standards, it is necessary for consumers to choose floor products. Only Xiangbei Only a large-scale flooring company like Yake Flooring can realize the one-time forming of the paint surface coating assembly line to ensure the smoothness of the paint surface and the uniform paint film.
4. Insufficient gaps are reserved around the floor during floor paving
When the floor is paving, there are insufficient reserved gaps around the floor, which causes the floor to arch. There is a gap between the floor and the ground. When people are walking, the floor moves up and down, and the sides between the floors rub against each other to cause edge collapse. Its characteristic is that the collapse of the floor usually occurs after a period of time after paving, in areas where people often walk, and there are many points. Observe that the floor and the wall are in close contact. Take measures to leave enough gaps around the floor, especially in areas such as doorways, kitchen walls, and balconies, to ensure that the reserved gaps are even. When the length of the pavement exceeds 8m, it should be partitioned and bridged.
5. Symmetrical placement of indoor furniture (heavy objects)
After the floor is paved, because furniture, bookcases, fish tanks and other heavier items are placed symmetrically on both sides of the room, the floor is suppressed, preventing the floor from absorbing moisture and expanding, and the floor cannot move, resulting in regional bulges, and people are walking around. In this area, the floor will collapse. The measure is to place heavy objects on one side as much as possible to ensure that one side of the floor moves freely.
6. Installation factors
Because the floor is too tight or the floor is slightly curved, the installation resistance of the floor is relatively large, and the knocking force is too large and uneven when the floor is installed, causing the partial edge of the paint film to fall off in a jagged manner. Its characteristic is that it can be found after installation, irregular and random distribution, and the number of occurrences is small. The measure is to use a floor head as the module to lean against the installed floor, and then gently tap the module with a rubber mallet to make the floor close to each other, and the force should be even during the tapping process.
In view of the analysis of the causes of the edges chipping of multi-layer solid wood composite flooring, I hope to answer your doubts, and at the same time, I hope that you can better understand the protection of the floor.
