The heating season has already begun, and some owners of floor heating have reported problems with arching and dampness in the newly paved floor. According to experts, this is mostly due to the fact that the pavement is not protected against moisture by standard. Plastic film can not be easily saved For the pavement specification of the floor under the geothermal environment, Wang Jun, an expert member of the China National Forest Products Industry Association and director of the Forest Products Inspection Center (Changchun) of the State Forestry Administration, said in an interview that according to the requirements of the Code for Wood Flooring, Acceptance and Use. For relatively damp ground or geothermal conditions, a plastic film should be laid on the ground, the joints should be overlapped by 20cm, sealed with waterproof tape, and then 2mm thick mats. In the environment of using geothermal heat, this layer of plastic film is very important, otherwise it is difficult to achieve moisture-proof effect. Because once the cement layer backfilled on the ground is not dry, the water vapor on the heating is smashed, and without the protection of the plastic film, the floor will be damp and the arch will be deformed. This layer of plastic film cannot be easily omitted for floors that have been heated and completely dry. Experts reminded that as long as the screed is re-formed before the paving floor, the plastic film should also be paved with moisture. The reporter found that some floor distributors in the market claimed that as long as the white mat was laid, the joints of the mats were sealed with tape, which also played a role in moisture prevention. However, Wang Jun denied this statement. He explained that under geothermal conditions, the tape is easier to degumming, and the moisture can be taken in, causing problems such as floor deformation and abnormal noise. Therefore, it is still necessary to install the specification, and lay a layer of plastic film under the floor mat, the joints overlap 20mm, and seal with tape. This makes it difficult to affect the floor even if the tape is degummed. Geothermal temperature should not exceed the standard It is also important to ensure that the geothermal heat is at a reasonable temperature while ensuring that it is paved in accordance with the requirements of the Code for the Paving, Acceptance and Use of Wooden Flooring. According to the introduction, according to JGJ142-2004 "Technical Regulations for Ground Radiation Heating", the maximum temperature of direct contact with the floor should be less than 42 °C, and the general control is ideal at around 38 °C. However, some water and floor heating and electric floor heating temperatures far exceed this standard. If the geothermal temperature exceeds the standard, the tape at the seam of the floor mat will be degummed and the moisture will rise. In order to put an end to this problem, it is necessary to control the water temperature of the water to warm, and the electric floor heating is best to use a dual temperature dual control system, and a two-pronged approach can achieve satisfactory results. Electric heating floor carefully selected Electric heating floor has a place in the market in recent years, that is, it has the function of heating and warming, and the practicality of the floor. It can have the effect of floor heating without the need for planing and backfilling. However, experts have warned that such new products are not sufficiently validated in the market. At present, there is no national standard or standard of practice, and it is necessary to choose carefully. Wang Jun said in an interview that the purchase of electric heating floors mainly depends on its temperature control system. The surface temperature should not exceed 28 °C. In addition, rapid heating has always been a feature of electric heating floors, but Wang Jun suggested that this function should not be blindly pursued, and frequent heating and cooling are not good for the floor. At the time of installation, it is still necessary to lay a moisture-proof membrane and add insulation according to the requirements of the Technical Regulations for Ground Radiation Heating. ■TIPS Geothermal is well laid out Home has geothermal, is it good to lay a wooden floor or a good floor tile? I believe many consumers are entangled in this. Experts say that the floor and floor tiles have their own merits, and which ones to choose depends on their own needs. The floor feels good and the warmth is good. Just choose a product that meets national standards for environmental performance. Floor tiles are stable, but in the north, summer may seem cold. In addition, some consumers have doubts about the thickness of the floor. There are 8mm, 12mm or even 15mm thick floor products on the market. Which geothermal environment is better for heat dissipation? Wang Jun explained that the thickness of the floor does have a certain influence on the heat conduction. However, in the continuous heating environment, the difference in thermal conductivity between the two types of products is not significant. Therefore, if the heating system in the living room is normal, the thick floor is fine. However, for district heating, and cold areas, thinner, more conducive to heat conduction.
