How to Read the Inspection Report of Laminated Floors (Part 2)
From a certain perspective, the inspection report of reinforced flooring is like the ID card or quality inspection certificate of the flooring. It is extremely important for each series of reinforced flooring and is also a direct basis for consumers to judge the quality of the flooring. Fully understanding it is beneficial for consumers to weigh the pros and cons of various numerical values and choose more suitable products. In the previous article, we specifically introduced four items: static bending strength, moisture content, internal bonding strength, and water absorption thickness expansion rate, as well as the impact of their numerical values. Today we will continue to discuss the remaining inspection items.
1、 Surface bonding strength
The standard definition of surface bonding strength refers to the ratio of the maximum load at which the surface layer of a specimen fails at a specified depth under tensile load perpendicular to the board surface to the loaded area of the specimen, also known as surface bonding strength. This reflects the bonding quality between the decorative layer on the surface of the reinforced floor and the substrate. The lower the value in this project, the easier it is for the decorative layer to peel off.
2、 Surface scratch resistance, wear resistance, cigarette resistance, pollution and corrosion resistance
These four items are all inspection items set up for the surface of reinforced flooring, and their qualification directly affects the use status of reinforced flooring in daily life. Among them, surface scratch resistance refers to the ability of the reinforced floor surface to resist scratches from hard and sharp objects; Surface wear resistance refers to the ability of a reinforced floor surface to maintain its original pattern and color under a certain friction force; Surface cigarette resistance refers to the ability of the surface to withstand the burning effect of cigarettes, which directly reflects the flame retardant performance of the floor; The surface resistance to pollution and corrosion refers to the ability of the reinforced floor surface to withstand the effects of acid and alkali chemical reagents, commonly used beverages, seasonings, etc.
3、 Impact resistance and formaldehyde release
Impact resistance is not difficult to understand, but what is difficult to understand is that its standard requirement is ≤ 10mm. In fact, this refers to the diameter of the indentation on the carbon paper surface of the reinforced floor after the ball impact test. Generally speaking, as long as it meets the standard, it is sufficient. And what really matters is the amount of formaldehyde released, the lower the value, the less harm it will cause to the human body.
The above is how to read the second part of the inspection report on reinforced flooring, and owners should also consider it comprehensively when purchasing.
