In order to assess the performance of the laminate flooring, Europe has established a quality standard for the inspection of laminate flooring, which limits the testable indexes such as wear resistance, water swelling ratio, formaldehyde emission, and density. Consumers also mainly choose laminate flooring based on these indicators. However, with the maturity and progress of laminate flooring technology, the original testing methods and testing projects have shown many unreasonable places. Because usually a certain brand of floor is sent to detect only a sample of the floor, strictly speaking, this floor does not represent all floor indicators. At the same time, there are too many factors in the detection process that can lead to errors in the test results, so European quality standards have begun to change or even eliminate some test methods.
Taking the wear resistance number as an example, the detection data can cause a large error due to the wear of the inspection tool, the difference of the sample to be inspected, or even the climate change, and the error is up to 40%. Therefore, the wear resistance is no longer in Europe. The number is used to measure the wear resistance of the laminate, and the wear resistance layer of Al2O3 is used as the test standard. According to the content of Al2O3 in the wear layer, it is expressed as AC1, AC2, AC3, etc. . In general, the purchase of composite flooring should be based on testable indicators, but if only focus on testable indicators or even "dead", it is obvious that some have lost. As a floor decoration material, laminate flooring is an overall effect, which is the comprehensive performance of a piece of floor after it is put together. However, no one testing institution has tested the indicators after the laminate flooring is assembled, and the comprehensive use effect after the floor paving is the product quality that the consumer can finally obtain.
Taking the assembly effect of the reinforced laminate floor as an example, consumers often only select a single board when purchasing a laminate flooring, but pay little attention to what effect it will be after assembling the board. Is there a difference between the two boards? Is the bite tight? Has the seam been treated after paving? In fact, the most prominent advantage of laminate flooring is wear resistance. The most prominent weakness is that the interface is warped, worn, and cracked, which affects the use effect and shortens the service life.
When purchasing laminate flooring, in addition to checking the testable indicators such as the number of wear resistance of the floor, you should also pay attention to the green environmental protection mark, and use the simple test method to test the assembly effect of the floor. You can look at the floor covering of the manufacturer's samples from different angles and see if the seams between the floors are obvious. If you find that the sample floor has a ribbed seam, it means that there is a noticeable height difference after the floor is assembled. It is best not to buy this product.
In addition, you can also align the two floors according to the seams, pick up one of them and see if the other floor will loosen without the glue. Because the bump groove snaps into the tight floor, you will find that they are very tightly snapped together, and it is almost impossible to separate them without much effort. Only when the interface with such a tight interface is assembled by professional assembly technology can the overall durability of the floor be achieved.
The last thing to note is that good flooring also needs a good installation team. Now the general manufacturers of composite flooring are installed free of charge. The key to the quality of installation is to look at the quality of the personnel and see if the installation workers have been professionally trained. Second, look at the supporting tools and see the workers. Whether the tool is matched with the product; the third is to look at the quality of the auxiliary material. The glue is an important auxiliary material for the composite floor. The quality of the glue directly affects the quality of the floor covering. If the floor meets the green standard, it does not use green environmental protection during installation. Type of glue, the harmful substances released by it still make you unable to use it with confidence. All in all, if you choose laminate flooring, you must shop around and compare their overall indicators.
Choosing laminate flooring, the most important indicator
In the home building materials city, consumers who choose the floor decoration materials often make a fuss in front of the laminate flooring: What is the wear resistance number? What is the rate of water swelling and density? I really couldn't understand it. I had to ask this form in a formal way, and I faked it and beat it to prevent being cheated. In fact, the purchase of laminate flooring does not have to keep an eye on these testable indicators, but focus on the comprehensive indicators of the product.
