With the prevalence of geothermal heating methods, the use of floor heating has gradually increased. Not only products, but also new technologies and concepts are emerging, making it hard to distinguish between true and false. Xiao Bian investigated the market and interviewed relevant experts and found that the salesman's arguments were more or less misleading in terms of materials, thickness, pavement, and cushions. Therefore, Jiuzheng Building Materials Co., Ltd. reminds everyone to buy before you try to avoid these "man-made" awareness.
Suspected of a solid wood floor can be used for geothermal floor solid wood floor only two, because only the hardwood material hardness is large enough to be used in geothermal environment. While in the home of the North Fourth Ring Store, another world brand of flooring brands directly played "The King of the Earth". The floor has undergone “exclusive high-temperature pyrolysis treatment technology†to solve the problem of easy deformation and easy cracking of the traditional solid wood flooring in the geothermal environment, and the thermal conductivity is greater than 8°C/h, has reached the national standard, so it can be fully used Geothermal environment. In addition to ash, there are ash wood in the flooring category. If pure solid wood flooring is more easily deformed?
Experts say that special treatment can be used because of 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 wood moisture goes to the air, Dry wood shrinkage. Ordinary solid wood flooring is easy to crack and shrink joints, it can not be applied to geothermal environment. Pure solid wood flooring that can be applied to geothermal environments must be specially treated. Currently, there are two ways: 1. High-temperature carbonization, that is, the raw material of the floor is subjected to high-temperature heat treatment at 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. 2. The wood is completely sealed with paint, that is, paint is used to seal the external surface of the wood including the backboard and the mouth, so as to prevent the wood from contacting the air and eliminate the influence of humidity on the floor.
If pure solid wood flooring is used in geothermal environment, installation should pay more attention. After the floor is sawn off, the newly generated section, whether cross-section or longitudinal section, must be sealed with wax to ensure that the floor is completely closed; the floor should be installed once as much as possible to prevent the seal of the floor lock during repeated installation of the floor. Destruction of the floor, so that the floor with the air humidity changes. In addition, it is necessary to check whether the ground is smooth and smooth before installation, if any convex sand particles are to be disposed of and cleaned. "The main reason is to prevent the moisture-proof coating of the moisture-proof film and floor from being damaged by sand particles."
Doubt two bamboo flooring is really heat-resistant deformation? Do you usually hear that the geothermal floor is laminate flooring and solid wood composite flooring, for bamboo geothermal floor, I really do not know whether it is competent.
Experts say the risk of cracking shrinkage bamboo flooring is usually two kinds of structure: one is the ordinary bamboo flooring (sequentially arranged); one is a three-layer bamboo flooring (vertical arrangement). Judging from 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 is a greater risk.
If it is a three-layer structure bamboo flooring, the dimensional stability of the three-layer solid wood composite flooring is very similar, and it can be regarded as solid wood composite flooring and can be used as geothermal heat. However, the moisture content of the surface layer should be controlled below 8%, otherwise there will be cracking of the floor surface. “If the bamboo flooring is carbonized, the stability will be better and the risk will be relatively low.†But experts still recommend that bamboo flooring be used for geothermal purposes. The risk of surface cracking and shrinkage seams will be higher than that of reinforced and solid wood flooring in the future. "Of course, if the bamboo flooring is used in geothermal environments, if the use of humidifiers, etc., can ensure the indoor humidity is maintained at 50% -60%, then the use of bamboo flooring is no problem."
Do the three thicknesses affect the thermal conductivity? In general, the lower the thickness of the floor, the greater the heat flow. When asked whether the thickness of the floor affects the thermal conductivity of a geothermal floor, a certain brand salesman stated that as long as it is a geothermal floor, it generally meets the thermal conductivity requirements. "No matter how thick the thickness is, since it is a geothermal floor, there should be no problem affecting the thermal conductivity."
This answer certainly cannot solve the consumer's doubts. Mr. Wang, who is interested in pure wood floor heating, said that the floor thickness is generally about 17mm. He does have some concerns that it will cause poor thermal conductivity. Mr. Zhang also said that the thick floor has a good foot feeling, but it will affect the indoor temperature, so I do not know how to choose.
Experts say little difference in continuous heating How to balance between thickness and heat conduction? 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 laminate flooring heat conduction faster than 12mm, but in a continuous heating environment, the difference between the two heat conduction is not obvious; 12mm foot feeling is better, the cost is higher. For places of continuous heating, in Beijing and other places where the room temperature is not very cold, if the heating system can guarantee the basic requirements of room temperature, you can choose a slightly thicker floor, 12mm-15mm are no problem. If you are in a particularly cold place such as the northeast, you can consider 8mm thick floor, so that the thermal conductivity is better.
Under geothermal conditions, the temperature experienced by the floor is relatively high. 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. "Try to choose the brand floor, not only the product quality is guaranteed, but also good after-sales service."
Doubt four or three layers of solid wood is the most applicable? Three-story engineered wood flooring is called most suitable for geothermal heating by many sales staff. Is this true?
Experts say that the risk of cracking shrinkage is greater. As a geothermal floor, it is best not to choose a floor that is too wide or too long. The greater the size of the floor, the greater the gap created in the geothermal environment. Especially in the case of three-layer solid wood laminate flooring with a wide surface, if the surface layer has a high moisture content during production, surface cracking will 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 will not occur. Therefore, three-layer solid wood composite flooring with a thickness of 2 mm or less must not be used as a geothermal floor.
Doubt Wu shop what best to mention when the floor heating floor, many sales staff have mentioned the floor mats. And they say that their home is good. Made of pure natural oak skin. No deformation, environmental protection, thermal insulation performance, and enhance thermal conductivity. Another one is using ordinary plastic film. Which kind of floor mat is good?
Experts say that 2mm plastic film is better to stick foil directly on the floor above the ground, playing a role in reflecting heat, not only can not heat, but also hindered the volatility of heat. If the floor mat is too thick, it will lead to elasticity, too much elasticity, the floor will move up and down, cause the locks to rub against each other, will produce a sound when walking, so it is not desirable. Under normal circumstances, the choice of 2 mm thick plastic film can not only play a role in shock absorption, but also can well block the moisture, and not too thick, will not affect the heat conduction.
No matter what kind of material such as cork or plastic film is used for the floor mat, the most important thing is to prevent moisture, and to ensure that the floor is isolated from the floor and prevent moisture from invading the floor and causing deformation.
Consumers can refer to the standard number of the floor implemented on the package at the time of purchase. Is there an industry standard? "Of course it is not ruled out that some companies sell floors that can meet this standard as floor heating."
