Some consumers reflected that last year he purchased reinforced laminate flooring from a well-known flooring brand in China. However, the use of the floor was less than six months. The noise in the room caused a noise. Now the noise of the floor has affected the normal life of the family, but it was repaired several times. Did not solve the problem. Businesses believe that floor noise is not a product quality issue, and there are no clear responses from several departments. Therefore, experts are asked to understand whether floor noise can be considered as a problem with product quality. Experts point out that floor noise cannot be regarded as a quality problem. There are many reasons that may cause this situation.
What is floor noise
Speaking of here, some consumers may ask, how can there be noises on the floor that touch the floor? Will the noise of the floor of your own home just be ignored by yourself? The noise of the floor is when people walk on the floor, up and down the floor. " The tremor "floor friction" between the floor locks or gears produces a sound. According to Wang Jun, expert member of the China Forest Product Industry Association and director of the Forest Products Inspection Center (Changchun) of the State Forestry Administration, if the floor is installed, it is always kept in contact with the floor (suspended installation) or between the wooden keel (keel installation), even if It is people walking on the floor, the floor will not be up and down 'shaking' the floor lock and the relative movement between the mouth, friction 'will not happen, the floor's noise' will not happen. Wang Jun believes that the root cause of "sound" in the floor is the gap between the floor and the ground."
There are no sound indicators for floor related standards
Wang Jun, a floor expert who has dealt with many complaints about floor quality problems, said that whenever a noise occurs on the floor, the first reaction of many consumers is the quality of the floor. This is understandable because consumers do not have this expertise, but some floor distributors and even comrades in the administrative law enforcement departments also believe that the noise of the floor is a product quality problem, and even misjudgment and misjudgment. After the installation of the floor sounds, the bottom can not be regarded as product quality problems?
Wang Jun said that the basis for assessing the quality of flooring products is the national standard of the product. According to reports, the current implementation of the laminate flooring standard GB/T18102-2007 laminate flooring inspection projects include the appearance of quality, processing accuracy and physical and chemical properties of three types of indicators. In the standard, there are no technical specifications and test methods for floor noise. Therefore, the sound of the floor after installation cannot identify the quality of the product. In particular, there is no sound when the floor is installed and checked. The same applies to solid wood flooring, engineered wood flooring, and bamboo flooring.
The floor sounds complicated
However, Wang Jun pointed out that from another point of view, before the pavement, if the measured floor warp is too large, after the floor is installed, the floor will move, it will produce a sound. The warpage of the floor is beyond the standard deviation of the floor. If the number of exceeding the standard exceeds the requirements of the inspection rules in the standard, it can be determined that there is a problem with the quality of the batch. However, he also pointed out that this certification process must be completed before paving.
Wang Jun also said that there are many other factors that cause floor noise, such as floor unevenness when paving the floor. According to its introduction, according to the GB/T20238-2006 requirements for wood floor covering, acceptance and use, the flatness of the floating paving surface should reach ≦3mm/2m, ie, 2m on the ground, and the maximum chord height should be Less than 3mm can be installed. In fact, the flatness of many houses far exceeds this target, and some of them reach more than 10mm. Once the flatness of the floor exceeds the standard, the floor will have a large gap with the floor after installation. The movement above it will feel like a sponge. Therefore, the newly installed floor will immediately feel a loud noise when walking on the floor.
In addition, according to the wood floor covering, acceptance and use of the specification "GB/T20238-2006 after the installation of the floor acceptance project "the main area can not have a clear sound"; after installation "the floor surface flatness ≦ 3mm/2m if the ground leveling When the degree is not up to the requirements, these two acceptance criteria are difficult to pass, and even changes in the environment during use can lead to floor noise.
Therefore, Wang Jun believes that the reasons for the floor noise after paving are very complex. Do not blindly identify product quality problems and require professional organization and appraisal.
