Analysis of common quality problems in the use of solid wood flooring

Solid wood floorboard is a traditional product developed earlier in China's flooring industry. Because the product is directly processed by natural wood, it has the characteristics of natural beauty, warm winter and cool summer, non-toxic, good foot feeling and noble. It is favored by consumers and has always been one of the leading products in the wood flooring industry. Especially in recent years, with the improvement of people's living standards, the interior decoration industry is booming, the production and sales of solid wood flooring are gradually expanding, and the trees used for solid wood flooring are also from the original beech, birch, and ash. A few tree species are the main species, and dozens of tree species dominated by imported tree species have been developed, which greatly meets the needs of society and people's lives. However, there are also many quality problems in the use of solid wood flooring, which are manifested in the following aspects:

1 distortion; 2 gap between the floor is too large; 3 arches; 4 floor height difference is too large; 5 floor corrugated; 3 floor cracks; 5 paint film peeling, cracks, wrinkles; 3 floor discoloration.

The reason is mainly caused by three aspects: paving quality, floor quality and improper use. The specific reasons are as follows:

1 The main reasons for the distortion of the floor are: a. The wood properties of the floor are not suitable; b. Improper processing technology and materials; The moisture content of the floor is not controlled uniformly or the floor moisture content is not suitable for the environmental requirements of the place of use.

2 The reasons for the excessive gap between the floors are: a. The moisture content of the floor is too large; b. The indoor environment is too dry; C. The quality of the floor is not high, causing the floor to move.

3 The reasons for the floor arching are: a. There is not enough reserved space between the floor and the wall base during paving; b. There is not enough space for gaps between the room and the room when there is no bridge treatment or bridge treatment; The moisture content of the floor when laying is too low; d. The room is leaking due to water, and the floor is soaked in water; e. The floor is damp or the keel is wet.

4 The reason why the height difference between the floors is too large is: a. The ground is not flat; b. The keel is not laid flat; C. Floor thickness deviation is large; d. The floor has been deformed; e. Floor grooving does not match.

5 reasons for the corrugation of the floor are: a. When the floor is laid, the cement floor is not flat and the keel moisture content is too large; b. The indoor environment is dry; The moisture content of the floor is too high; d. The indoor environment is too humid and the floor moisture content is low.

3 The reasons for cracks on the floor are: a. Wood properties are not suitable for making wooden floors; b. The moisture content of the wooden floor is high, the indoor environment is dry and the humidity is low.

3 The reasons for the peeling, cracking and wrinkling of the paint film are: a. The paint performance is not suitable for the slab type of the slab, so that the adhesion property of the paint film and the wood cannot meet the use requirements, and peeling occurs; b. The toughness of the paint film can not meet the natural wet shrinkage and shrinkage of the wood, resulting in cracking of the paint film; C. Peeling of the topcoat caused by poor adhesion of the paint topcoat and the primer; d. Peeling, cracking, and wrinkling of the paint film due to unscientific paint process; e. The film is wrinkled and peeled off due to the high moisture content of the floor; f. Cracking or peeling of the paint film due to low moisture content of the floor; Due to the harsh indoor environment, if the indoor environment is too dry or humid, the paint film will be destroyed.

3 The main reason for the discoloration of the floor is: a. The wood itself is affected by the external environment, such as sunlight, indoor air environment; b. Changes in paint caused by the external environment; C. The change in the chemical reaction between paint and wood.

To avoid quality problems during the use of the floor, you must do the following:

1. When laying the floor, the floor, wall and wall should be dry.

2. The ground should be flat.

3. The keel and the liner used should be dried and the moisture content should not exceed the local equilibrium moisture content.

4 The keel plane should be flat.

5. It is best to lay a layer of plastic film on the floor before laying the floor.

6. The moisture content of the wooden floor should be within the standard range and should not exceed the local equilibrium moisture content.

7. For the manufacturer, it is necessary to scientifically select the tree species for the floor, and for the tree species that are not suitable for the floor, it must not be used.

8. Due to the different species of wood, the physical, chemical and mechanical properties of wood are different, so the factory should test when using paint. Confirm the adaptability of the paint to the material, and scientifically select the paint to ensure that the paint meets the performance.

9. When the wooden floor is laid, sufficient expansion joints should be reserved according to the size of the room between the floor and the wall base.

10. During the laying process of the floor, try not to use water-soluble adhesives to avoid expansion and deformation caused by the absorption of moisture from the floor;

11 Never use cement to fix the keel when playing the keel.

12. Do not be too dry in the indoor environment, nor too humid, especially in the winter in the north, try to maintain a certain humidity in the room to prevent the wooden floor from cracking and deforming.

13. When cleaning the floor, try not to clean the floor with a drip with a drip.

14. Avoid the floor being exposed to strong sunlight to prevent discoloration, deformation and cracking of the floor.
