In fact, knowing this variable is easy. Find a 360-grit sandpaper on the spot and try it out. Start grinding according to what the dealer says. Turn a meter back and forth. When the floor surface begins to wear out, count it and you grind it. How much back and forth, this time the number of revolutions is the initial wear resistance of the floor, continue to wear it! Grind to a certain number of rotation you will find that the place has been worn no aluminum oxide surface, and then count, How many times you are grinding, then you get the end of the floor. The end value is usually much higher than the initial value. Probably, some businesses will also tell you that the target is the median value. It doesn't matter. Calculate the average of the two values ​​you got before. It is it!
In the course of the experiment, those floors with rapidly worn surfaces must be floors without wear-resistant layers; and floors that wear before 6,000 rpm may have wear-resistant layers, but they must be domestically unqualified products; 6000 rpm The above products can be called reinforced flooring that meets the national standard. In general, the initial wear resistance value of imported laminated flooring is more than 9000 turns.
