In recent years, more and more residential communities have adopted low-temperature radiant heating systems, ie, geothermal floors. This heating method has a large radiation surface and requires low temperature for water supply. The entire floor is uniformly heated and hot air rises from the bottom up. Hot comfort feeling. In addition, its maintenance costs are lower than traditional heating methods. While consumers enjoy the benefits of geothermal heating, they are faced with the problem of how to choose materials to lay on the ground.
â– Geothermal floor needs to meet three conditions
The floor heating technical personnel introduced that the selection of geothermal floor should be based on the specificity of geothermal heating methods: to adapt to cold and heat repeated conversion and conducive to heat conduction, geothermal floor needs to meet two conditions: small deformation; conducive to heat conduction.
At present, several types of floorings are popular. Under the same environmental conditions, solid wood floorings have a greater amount of deformation than laminate floorings, and laminate floorings have a greater amount of solid wood flooring. The reason for the small amount of deformation of multi-layer solid wood flooring is its base material, each horizontal and vertical staggered and intertwined with each other; the back also has dense deformation-resistant grooves, which decomposes the stress generated by the heated surface, and therefore its deformation is minimal.
The thermal conductivity of the floor is related to the thickness of the floor. The thickness of the solid wood floor is similar to that of the reinforced floor. The difference is that the anti-deformation groove on the back of the solid wood floor facilitates air circulation and reduces noise; the surface of the reinforced floor is resistant to metal oxides. In the grinding layer, heat spreads very quickly and evenly over the surface.
Not all wood floors can be floor-heated, and floor-heating floors are preferred.
The floor heating system achieves the purpose of heating by heating the floor. The floor always maintains a high temperature, and the ordinary floor is easily deformed in such an environment. Therefore, after installing the floor heating system, it is necessary to select the flooring suitable for the floor heating system.
Laminate flooring is the main force
According to the characteristics of the floor heating, floor heating should meet three conditions: 1. adapt to cold and heat repeated transformation, small deformation; 2. conducive to heat conduction; 3. moisture resistance and waterproof.
Since wood is a poor conductor, the greater the thickness, the more adverse the heat conduction. At present, most floors on the market such as 12-18mm thick solid wood flooring, bamboo flooring, ordinary solid wood composite flooring and laminate flooring with a thickness of more than 8mm are not suitable for ground heating radiation systems, otherwise it will affect heat conduction or cause floor deformation .
In the same environment, the deformation rate of solid wood flooring is the largest, followed by the strengthening of wood flooring, and the deformation of solid wood flooring is the smallest, because the base material of each layer is interlaced horizontally and vertically, and they are mutually restrained; the back also has dense deformation-resistant grooves, decomposition The stress generated by the heated surface.
The thermal conductivity of the floor is related to the thickness of the floor. The thickness of the solid wood floor is similar to that of the reinforced floor. The difference is that the anti-deformation groove on the back of the solid wood floor facilitates air circulation and reduces noise; the surface of the reinforced floor is resistant to metal oxides. In the grinding layer, the heat is diffused very quickly and evenly at the surface and the indoor temperature is easily controlled.
However, the surface layer of multi-layer solid wood composite flooring is thin, not easy to care for and cannot be refurbished, which affects the service life. The price of three-layer solid wood is relatively expensive. In view of the above problems, strengthening the floor has always been the main force of geothermal flooring. Laminate flooring has obvious advantages in terms of floor deformation rate, surface wear resistance, cleaning and maintenance.
In addition, the quality of the floor is "three-point floor and seven-point installation", and the installation standards for professional floor heating are higher. Therefore, it is better to provide professional installation by the manufacturer and avoid installation by the construction team.

The silicon tube is a kind of new composite pipe with silica gel solid lubricant.The main raw materials are high-density polyethylene and the core layer is the lowest friction coefficient of the solid lubricant silica gel.Widely used in optical cable communication network system.
Performance characteristics of silicon - core tube
1. The silicon core layer of the inner wall is solid, permanent lubricant, the friction property of the inner wall of the silicon core remains unchanged, and the cable can be repeatedly drawn in the pipe;
2, its inner wall of the silicon core layer is pressed by synchronization in high density polyethylene pipe wall, and evenly distributed throughout the pipe wall, the wall of the silicon core layer and high density polyethylene with the same physical and mechanical properties, not peeling off, out of, and silicon tube with life;
3. The silicon core layer of the inner wall does not react with water, and the pipe can be flushed after the accident.
4. The radius of curvature of silicon tube is small (10 times of its outer diameter).When the tube is in the bend and the gap, it can be determined according to the environment, without any treatment, no need to make a transition;
5. The length of each (disk) silicon tube can be made to any length.In general, the standard length of each (disk) silicon tube is 2000 meters in terms of the convenience of transportation safety and construction.
6. The construction is convenient and the project cost is reduced.The silicone tube is not required to coat the tube, and it can be used directly in the pipe line, without the tube.Since the length of the silicon tube is generally 2,000 meters, the well can be set up every 1,000 meters, and it will only take 15 minutes for each 1000 meters.
Product appearance
High density polyethylene (HDPE) silicon inner and outer walls should be clean and smooth, not allowed to have bubbles, obvious scratches, dents, impurities, color inequity defects.Pipe ends shall be cut flat and perpendicular to the tube axis.The inner wall of silicon core should be tightly welded and no deform phenomenon.The outer wall of the pipe is clearly marked.
Application fields: outdoor communication cable and cable pipeline system, public information network, public transport system, cable network and highway communication engineering construction.
