There are four key inspection indicators for strengthening the floor. The amount of released formaldehyde, the degree of surface wear, the thickness of water absorption, and the geometry of the floor. 1, formaldehyde emission determination: use good sealing performance of large mouth bottles, saw the same size of several alternative brand model, into a different bottle, sealed 24 hours later, open the bottle, one by one, you will compare Out, which brand of floor formaldehyde emission is small. If you are afraid of being inaccurate, you can have two people, have heard of each other, and have a better grasp. 2, the surface wear resistance: 180 sandpaper (sandpaper thickness, the problem is not), the same person, with the same strength and methods, continuous friction back and forth to the same place on the floor, 50 times. There is no aluminum oxide floor, it is very likely that the wood-grained paper will be seriously damaged. 46 grams of wear-resistant paper on the floor, the surface is basically no serious scratches; 38 grams or less grams of wear-resistant paper, the surface will have varying degrees of wear. 3, water thickness expansion rate: sawing the size of the alternative sample, numbering, into the boiling water, 5-8 minutes. Take it out and compare the degree of swelling on their edges. It is best to use a micrometer to measure the thickness of the measuring point of the template and make a mark. After soaking in boiling water, take out and measure the thickness, and calculate the relative water swelling rate of the floor after immersion in boiling water. 4, the geometry of the floor: This comparison test needs to use a whole board for comparison. a) Put the two floors together and touch the height of the joints. You can also consciously feel and compare the models selling floors. The difference between brands should be obvious. b) Secondly, look at the tightness of the splice seam. There are a few corners on the floor and the seams will not be tight. This reflects the accuracy of the laminate flooring processing.

First of all, we must know the indicators to identify whether or not to strengthen the floor. We must also know the simple and easy method of identification. We believe that strengthening the floor to such a degree as to be untrue today has a lot to do with consumers' lack of discernment ability. A few days ago, some people also wrote about how to choose to strengthen the floor, such as the quality of these indicators: look at the brand, price, origin, wear, formaldehyde, etc., how can consumers see it?
