Modern room decoration, the floor is essential. At present, people generally use the tongue and groove floor, which is convenient and firm to install. However, when consumers buy the floor, they often only pay attention to the floor surface, pursue the color difference and no scar, and ignore the width of the mouth. As a result, the hidden danger is brought back home.
According to the person in charge of Quanzhou Nature Flooring, according to national standards, the width of the floor of the floor must be 5 mm, which can be really firm after installation. At present, there are many small workshops that produce a floor with a width of only 3 mm, which is not easy for consumers to detect. After a period of use, because the interconnection between the floor strips is not strong enough, even if the base is done well, it will still make an unpleasant noise when walking.
Then, is the floor that is not up to the standard width due to the producer’s negligence? The industry has solved this mystery for us. As we all know, there are wedges on both sides of the tongue-and-groove floor, commonly known as "male slots". Because of the calculation of the floor area, it is easy to be seen by consumers in the width and thickness of the tongue-in-the-mouth. If the producer wants to "improve the utilization rate of wood" To achieve "cost reduction", and only to make an idea on the width of the mouth. For example, a floor with a length of 900 mm and a width of 90 mm requires a wood of 905 mm in length and 95 mm in width. When the width of the tongue is reduced to 3 mm, the area of ​​the required wood is reduced accordingly. Such a long-term accumulation is a big "windfall" for producers.
Therefore, when purchasing the floor, consumers should carefully measure the width of the tongue in addition to the appearance. It is advisable to buy some floor dealers and specialty stores with good reputation and large scale.
