Do not doubt a solid wood floor can be used for geothermal. Recently, consumers Mr. Wang in the selection of flooring, the salesman told him that solid wood flooring only beech wood material hardness enough, can be used in geothermal environment. The other floor brand world friend has directly played the "geothermy king" - a real billboard against geothermal pure solid wood flooring. On the brochure, the floor was subjected to the “exclusive high-temperature pyrolysis treatment technology†to solve the problem of the easy deformation and easy cracking of the traditional solid wood flooring in the geothermal environment, and the thermal conductivity was greater than 8°C/h, reaching the national standard. So it can be fully used in geothermal environment. Mr. Wang said that for pure solid wood flooring used as a floor heating is also in doubt, such as pure solid wood flooring is more easily deformed?
Experts said that special treatment can be used after the China Forest Products Industry Association expert Wang Jun introduced that due to the geothermal environment, the floor needs to withstand a certain amount of heat, when the water in the air is absorbed into the wood, the wood will expand; when the air is dry The evaporation of wood moisture causes the wood to shrink. “Ordinary solid wood flooring is susceptible to cracking and shrinkage and cannot be used in geothermal environments.†Pure solid wood flooring that can be applied to geothermal environments must be specially treated. At present, there are two ways: high-temperature carbonization, that is, the raw material of the floor is heat-treated at a temperature of 160°C to 230°C, so that the moisture absorption function of the wood is reduced or the influence on the change of the air humidity becomes insensitive; the wood is completely sealed with the paint, and is used The external surface of the wood exposed by the paint, including the backboard and the mouth, is closed to avoid contact between the wood and the air, eliminating the influence of humidity on the floor. If pure solid wood flooring is used in geothermal environment, the floor should be installed as much as possible, to prevent the seal coating at the floor lock from being damaged during the repeated installation of the floor, and to cause the floor to deform with changes in the air humidity. In addition, it is necessary to check whether the surface of the ground is smooth and smooth before installation, and if any convex sand particles are to be disposed of, prevent the moisture-proof coating of the moisture-proof film and the floor from being damaged due to sand particles.
Do not doubt the deformation of bamboo flooring heat resistance nowadays, bamboo flooring has become a favored product for many families. Some salesmen said that bamboo flooring has been specially treated and suitable for geothermal environments. “Bamboo flooring must be high-temperature carbonized, so it is not afraid of high temperatures.†But consumers said that the geothermal floor is a laminate flooring and engineered wood flooring. For the bamboo geothermal flooring, I don’t know if I can handle it.
Experts say that the risk of cracking shrinkage bamboo flooring is usually two kinds of structure: ordinary bamboo flooring (arranged in a row) and three-layer bamboo flooring (vertical arrangement). From the perspective of the amount of deformation, the deformation of ordinary bamboo flooring is smaller than solid wood flooring, but it is much larger than solid wood flooring and laminate flooring. Therefore, in geothermal environment, the use of ordinary bamboo flooring has certain risks. However, experts say that if it is a three-layer structure of bamboo flooring, and three-layer solid wood composite flooring is very similar in dimensional stability, can be considered solid wood composite flooring, can do geothermal. However, the moisture content of the surface layer should be controlled below 8%, otherwise there will be cracking of the floor surface. If it is carbonized bamboo flooring, the stability will be better and the risk will be relatively reduced. Of course, if you use a humidifier, etc., to ensure that the indoor humidity is maintained at 50% ~ 60%, then there is no problem with using bamboo flooring.
Do the three thicknesses affect the thermal conductivity? In general, the smaller the thickness of the floor, the greater the heat flow. Does the thickness of the floor affect the thermal conductivity of the floor? Some consumers said that a thick floor feels good, but the thickness of the floor above 12mm will not cause poor thermal conductivity, so I do not know how to choose. A brand salesman stated that as long as it is a geothermal floor, it generally meets the thermal conductivity requirements. Regardless of the thickness, since it is a geothermal floor, there is no problem affecting the thermal conductivity.
Experts say little difference in continuous heating How to balance between thickness and heat conduction? Experts said that in general, the greater the thickness of the floor, there is indeed a certain impact on the conduction of heat, but "the impact is not great." No matter whether the thickness is 8mm or 12mm, it can be used in geothermal environment. In contrast, 8mm floor heat conduction faster than 12mm, but in a continuous heating environment, the difference between the two heat conduction is not obvious; 12mm foot feel better, the cost is higher. For places with continuous heating, if the heating system can guarantee the basic requirements of room temperature, you can choose a slightly thicker floor.
In addition, under geothermal conditions, the floor withstands relatively high temperatures. With the increase of temperature, the release rate of formaldehyde on the floor is accelerated. Therefore, floors with low formaldehyde emission should be selected as much as possible.
Doubt four or three layers of solid wood is the most applicable? Three-layer parquet is a mainstream product of solid wood flooring, this floor is made of three layers of wood compressed vertically and horizontally. In the market, three-layer parquet is recommended by many brands as the most suitable for geothermal heating. Is this true?
Experts say the surface layer moisture content is very important as a geothermal floor, it is best not to choose too wide or too long floor, the greater the size of the floor, the greater the gap in the geothermal environment. In particular, a three-layer solid wood composite floor with a wide surface and a single width, if the moisture content of the surface layer is too high during production, cracking may occur under geothermal conditions. Therefore, when producing three-layer solid wood flooring for geothermal heating, the moisture content of the surface layer must be strictly controlled. Under geothermal conditions, when the moisture content of the local slab changes, the amount of slat expansion is different, and there will be obvious rib-like ripples on the floor surface of the floor. If the thickness of the three-layer parquet flooring surface is more than 3mm, this phenomenon is not easy to appear. Therefore, a three-layer engineered wood floor with a surface layer thickness of 3 mm or less is not suitable as a geothermal floor.
Doubt Wu shop what best to mention when the floor heating floor, many sales staff have mentioned the floor mats. Conlon floor salesman said that they use a softwood floor mat made of pure natural oak, no deformation, environmental protection, insulation performance is also good. Friends of the world floor, said the product used plastic foil affixed with foil, so as to "enhance thermal conductivity." In addition, most brands are common floor mats. Which kind of mat is good?
Experts say 2 mm plastic film better experts said that foil directly paste on the floor above the ground, play a role in reflecting heat, not only can not heat conduction, but also hinder the volatility of heat. If the floor mat is too thick, it will cause the floor to move up and down, causing the locks to rub against each other, making it easy to produce audible noise. Under normal circumstances, the choice of 2mm ordinary plastic mat can not only play a role in buffering and shock absorption, but also can well block the moisture and will not affect the heat conduction. Installation and maintenance should be in place, humidity should be appropriate, the normal ambient humidity of the floor should be more than 40%, and the optimal humidity is 50% ~ 60%. Because the environment is too dry, it can also lead to the shrinkage of the laminate flooring in the winter. Therefore, under the geothermal environment, adjusting the humidity of the room reasonably is the most effective way to prevent the deformation of the floor.
Care must be taken when using multi-layer engineered wood flooring for floor heating. The thickness of the floor covering is mostly 0.6 mm. The surface compressive strength is relatively weak. If the stool legs of the room are not protected, when people sit on the stool, Will crush the surface of the floor. The temperature should be controlled. Before the floor is installed, the geothermal system should be pressure tested to prevent damage to the floor due to leakage from the geothermal pipeline. The water supply temperature of the geothermal system should not exceed 60°C. In the initial stage of geothermal heating, the temperature should be raised gently. The temperature of the water supply should be controlled at about 10°C higher than the prevailing ambient temperature, and should not be higher than 32°C; it should be run continuously for 48 hours; The water temperature rises by 3°C every 24 hours until the designed water supply temperature is reached; the maximum ground temperature directly contacting the floor cannot exceed 42°C.
