There are many performance indicators for laminate flooring technology. In the selection, the following three factors are generally considered: wear resistance, formaldehyde content and water absorption thickness expansion rate. Knowing the purchase knowledge will make it easier to choose the wooden floor. Wear resistance is an important indicator of laminate flooring. Objectively speaking, the higher the wear resistance, the longer the service life should be, but the level of wear resistance is not the only criterion for measuring the age of the floor. Under normal circumstances, the reinforced laminate flooring wear resistance reaches 10,000 rpm, and the products with less than 10,000 rpm may have different degrees of damage after 1 to 3 years of use. Formaldehyde content is an indicator that has not been valued by consumers, so it is plagued by the pungent odor of many consumers after construction. This phenomenon is caused by excessive formaldehyde content. According to European standards, the formaldehyde content per 100 grams of floor should not exceed 9 mm, otherwise it is unqualified, so this indicator is a key indicator of whether the products we choose are harmful to the body. The water absorption thickness expansion rate index is deemed to be qualified within 3%, otherwise the floor is exposed to humidity or the ambient humidity is high, otherwise the floor is exposed to humidity or the ambient humidity is high, and the surrounding seal is not tight when assembling. There will be bulging and deformation, which will affect normal use. Experts especially reminded that consumers should carefully ask the difference between different grades of laminate flooring when purchasing laminate flooring. After picking up the product, check whether the code on the package matches. At present, it is worth noting that some dealers in the market have over-exaggerated the promotion of laminate flooring, and even reached an increasingly outrageous level. For example, the wear resistance of the wooden floor surface is marked by 30,000-50,000 rpm. In fact, the wear resistance number is only an indicator of laminate flooring. The high number of revolutions can only indicate that the wear resistant layer has a large amount of aluminum oxide. However, other physical properties of the wood floor may not be qualified, such as stain resistance and impact resistance. Sex, chemical resistance, comfort, etc. Usually the wear resistance reaches 6000 rpm, which can fully meet the needs of consumers. It is too high and useless.
