In the first half of this year, CCTV's "Weekly Quality Report" did such an experiment. The amount of formaldehyde released from the 24 floor samples at different temperatures was measured separately. They were found to be fully qualified for formaldehyde release at 23 ° C as specified by the standard. However, with the increase of temperature, these formaldehyde emission levels at room temperature are in line with the national standard, and the release of formaldehyde has been differentiated. When the temperature is close to 50 °, the original amount of formaldehyde is out of the reference value.
At the moment of consumption upgrades, geothermal flooring has gradually entered the family of many people. According to statistics, in 2016 alone, the production and sales volume of solid wood geothermal flooring reached 5 million square meters; and the annual growth rate of production and sales exceeded 25% (data source: China Forestry Industry Association Social Responsibility Report), which is the average development speed of the entire flooring industry. 5.7 times, 80% of the floor brands on the market have launched solid wood floor heating products.
The new technology brings convenience and comfort, but also brings many hidden problems, such as how the floor resists the temperature change of underground thermal expansion and contraction. What changes in formaldehyde release with increasing temperature? A major test for flooring companies, but also a balance between good and bad brands.
What should we do with geothermal floor? We will see the richness of the domestic oak floor.
When the glue is edible, what is the temperature?
Some people may have doubts. Why does the release of formaldehyde from the national standard exceed the national standard after the temperature of the local hot floor rises? This is mainly because when the temperature rises, the glue in the floor begins to volatilize, if the quality of the glue Not good, then the formaldehyde release will exceed the standard.
The glue used in the geothermal floor production and installation process directly affects the health of the whole family. Therefore, a good geothermal floor must first be environmentally safe. For example, Fudeli's three-layer solid wood flooring, the board-to-board bonding is made of edible grade imported Finnish tyco, which is environmentally friendly to meet stringent EU environmental standards and is also widely used. Among the baby products and tableware, it has been approved by the FDA (Food and Drug Administration). In the installation of the floor, there is no need to add any glue, which is truly environmentally safe.
Starting with the selection of materials, the first "baked" test across the geothermal floor
The biggest difference from ordinary flooring is that the geothermal floor changes with the temperature, and the physical properties of the floor bottom layer vary greatly. Under the influence of high temperature, the floor is heated and swelled, and it is easy to bulge; in addition, the floor moisture is missing in the case of long-term high temperature, which causes the floor to shrink and crack. Therefore, the first test of geothermal floor is - temperature.
To this end, the Fudeli geothermal floor first exerts strength on the selection of materials, and selects four kinds of high-quality woods with stable properties and not easy to crack, such as oak, Asian pear, teak and merbau. Secondly, the appearance must be carefully selected and the texture is moist. Fully solid wood, supplemented by hand-drawing, engraving, pure vegetable oil glazing and other dozens of processes. Do both internal and external repairs.
Diligently repairing the floor of the geothermal floor, Fu Deli solves three major problems

The technical barriers to geothermal floor protection are mainly used to solve the problem of dry shrinkage and swelling caused by the temperature rise of the floor. To solve these problems completely, it is impossible to solve the problem by simply selecting the right materials. It also requires innovative breakthroughs in key technologies.
In solving the problem of floor shrinkage, Fudeli geothermal floor adopts computer full-time numerical control, strictly controls the moisture content of wood below 9%, and the side 4 double-layer waterproof iron-iron paint blocks moisture, plus the lock protection film is silent and water-proof. In order to ensure that the floor will not shrink due to the loss of free water in the geothermal environment;
In solving the problem of swelling of the floor, Fudeli developed a new 6-face sealant, waterproofing technology and other new technologies, evenly coated the 6 surfaces of the floor with waterproof paint, and simultaneously carried out 11 primers on the front and back sides. Road surface treatment, realistic 360-degree waterproof and moisture-proof. Thereby solving the problem of floor moisture absorption expansion;
The flooring industry has the saying of “three-point floor, seven-point installationâ€. After solving the above two problems, each floor actually has good properties such as water lock, moisture resistance and stability. The next problem is how to make them fit together. Fudeli adopts a new generation of enhanced version of the 3D rodent tongue tongue, the mother groove is thicker and the bite force is more than 800 cattle, which solves the problem of internal deformation of the floor and avoids the local uplift of the floor with increasing temperature.
Quality and cost can reflect the quality of an entrepreneur. Low cost is the level of entrepreneurs. Low quality is the shame of entrepreneurs. As an entrepreneur, he is obliged to provide consumers with high quality products. With this belief, Fudeli has been standing at the forefront of the Chinese flooring industry since its inception in 1994.
