The base material is an integral part of the composite floor. The basic base material composition is almost the same. It just depends on the quality, and it doesn't matter what brand of base material; The floor base material accounts for more than 90% of the whole floor component (calculated by solid), and the base material accounts for about 70% of the cost structure of the whole laminate floor. The price and supply of wood resources are the core factors of substrate cost. In addition, the cost of the base material is different due to the difference of its material components and the use of adhesives, so as to the difference of processing technology and equipment.
Factors affecting the stability of floor substrate:
The main factors affecting the stability of floor are the nature of raw materials and the level of processing technology. Different materials have different density and hardness, and the level of processing technology will also affect the moisture content, wear resistance and other factors of the final product. The length, width and thickness of wood flooring products will also have a certain impact on its stability. Generally speaking, under the same conditions, the thicker the thickness, the more stable it is, that is, the less easy it is to deform. The deformation of floor substrate is generally caused by factors such as product itself, construction, external bad environment, temperature change and humidity. For example, improper drying treatment, too low moisture content, too shallow back groove, insufficient expansion joints during construction, thermal expansion and cold contraction caused by temperature difference, etc.
The floor thickness has little effect on thermal expansion and cold contraction. Because the floor is a wood product, it has the absorptivity of the tree itself. If the humidity around the floor is too high, the floor will expand and deform because of too much moisture. Therefore, most wood floor products are treated by moisture-proof processes such as paint, and attention should also be paid to measures such as paving moisture-proof film on the ground during installation to reduce the impact of moisture on the floor. The increase of wood floor thickness can also more effectively resist moisture intrusion into the floor and reduce the deformation caused by moisture.
