Sports wood floor cracking like skin chapped, dry hair bifurcated, wood as a kind of biology, water shortage will also have problems, using the door shows cracking. This kind of split is very firm, and there is no compromise due to the price.
The solid wood floor bought by hua10000 and hua1000 has the same risk of cracking if it is not well maintained; this kind of cracking is unpredictable, which may occur in the early morning and evening, spring, summer, autumn and winter, and in the north and South; what's worse, once cracked, it is difficult to recover. Such a variety of cracks, although a word, but let people see a hard time; this kind of cracks, not to say pain through the heart, but often see, such as a lump in the throat.
1. The anisotropy of wood, which is the inherent property of wood as a natural material. From a scientific point of view, due to the natural nature of wood, the material arrangement direction of its cells is very random, so that wood in different directions, with the change of external conditions, will produce different degrees of shrinkage, and then will produce cracking and other phenomena. In other words, wood is different in all directions.
2. The moisture content of wood is the moisture content of wood, which is the percentage of the ratio between the moisture content of wood and the quality of wood, expressed by MC. The moisture content of wood itself is closely related to the cracking of the door. Its moisture content can be controlled by drying and measuring. The following formula is commonly used for calculation:
In the formula, g wet is the mass of wet wood / g; g dry is the mass of absolutely dry wood / g.
3. Fiber saturation point, seriously speaking, when the free water in the wood completely evaporates and the amount of water absorbed in the cell wall is in a saturated state, it is called fiber saturation point (FSP). Generally speaking, if the moisture content of wood is higher than this point, the shape of wood will not change greatly; if the moisture content of wood is lower than this point, the shape of wood will change greatly with the external changes.
