The weather is getting colder, and the geothermal floor has become a hot spot in the home improvement market. With the improvement of residents' pursuit of quality of life and the advancement of flooring technology, in the field of geothermal flooring, traditional ceramic tiles, stone materials, composite solid wood flooring and laminate flooring have gradually been replaced by geothermal solid wood flooring, and geothermal flooring has entered The era of solid wood."
Geothermal floor requirements are strict
Commonly known as geothermal ground heating, the whole ground is used as a radiator. The heat medium in the radiation layer of the floor heating network uniformly heats the entire ground, and uses the law of the ground's own heat storage and heat to radiate from bottom to top to achieve heating. the goal of. Compared with the traditional heating method, geothermal heat can bring a refreshing feeling of “cooling the feetâ€. Due to the special nature of geothermal heat, the requirements for the floor are particularly strict.
Expert analysis, qualified geothermal floor must have three major characteristics. First of all, heat dissipation is better, "should be thin and not thick." Wood and bamboo are good natural materials. The heat from the ground is transmitted to the surface through the floor. There is bound to be heat loss. The ideal floor can minimize these losses. Therefore, in order to reduce the loss of thermal energy and reduce the heating operation and maintenance expenses, the thickness of the plate should not exceed 8 mm and the maximum should not exceed 10 mm.
Secondly, the material stability is better, the use environment of the geothermal floor is complicated, especially in the northern region. The ground in the non-heating season has to withstand all kinds of moisture, and the floor temperature has to rise suddenly when heating, the floor must bear the "temperature" and "humidity". "The double change." Therefore, the geothermal floor must be purchased with good material stability. In addition, the geothermal floor has a complicated environment for use, and it has strong moisture and heat resistance. Especially in the northern region, the ground in the non-heating season is subject to various moisture, and the floor temperature is suddenly increased when heating, and the floor must withstand "temperature" and " The double change of humidity, so the geothermal floor must have good material stability as an important reference standard.
Finally, wear resistance is also required to be durable. Since the geothermal floor is generally thin, the surface layer is generally 0.3 to 0.6 mm, and the wear resistance of the main surface is higher than the conventional index.
Solid wood geothermal enters the market
Before the advent of geothermal solid wood flooring, it was generally believed that solid wood flooring was not suitable for use as a geothermal floor. Due to the unstable water content of solid wood flooring, it is easy to dry and crack in winter, and it is easy to get wet in summer rainy season. Solid wood is susceptible to environmental humidity and has the characteristics of shrinkage and wetness, which leads to certain limitations of stability in flooring. The three main points required for geothermal floor are just the opposite.
Therefore, the floors that can be used for geothermal paving in the market are mainly laminate flooring and parquet. Since the reinforced laminate flooring is pressed by high temperature, the internal water content is reduced, and the floor is not easily deformed; the solid wood composite floor has a special structure of expansion joints, and the stress generated by the heat is decomposed and the deformation amount is small. The two are relatively stable, and at the same time the price is cheaper than the solid wood floor, which becomes the main choice for geothermal floor.
However, composite solid wood flooring and laminate flooring also have their own problems. The biggest problem is environmental safety. Because of the characteristics of these two flooring products, although there is no problem under normal temperature conditions, formaldehyde release is difficult to control under long-time heating conditions, so indoor formaldehyde is generated. The problem of exceeding the standard hazard.
