Knowledgeable people know that formaldehyde emission, the degree of surface abrasion, thickness swelling and floor geometry test laminate flooring is the most critical indicators, specifically how we test it? Xiaobian Chinese wood floor for your interpretation.
1, formaldehyde emission measurement: use good sealing performance big mouth bottles, cutting the same size model several alternative brands, into a different bottle, sealed 24 hours after opening the bottle, one by one smell, you will be more out which brand of flooring formaldehyde emission small. If the fear is not accurate, can two people, has smell, compare grasp.
2, the degree of surface wear: Use 180 grit paper (sandpaper thickness, the problem is not), the same person, with the same strength and method, continuous back and forth friction floor of the same place, 50 times. No aluminum oxide on the floor, it may be seriously damaged wood paper. 46 grams wear-resistant paper floor surface is substantially devoid of serious scratches; 38 grams or less number of grams of wear-resistant paper, the surface will have different degrees of wear and tear.
3, thickness swelling: cutting the size of the approximate alternative model, serial number, into the boiling water, 5-8 minutes. Out to compare the degree of expansion of their edges. The best prior micrometer to measure the thickness of the template of the measuring point, make a mark. After water immersion, and then out to measure its thickness, can be calculated after water immersion, the relative thickness swelling floor.
4, floor geometry: this comparison test requires a single piece of board to compare. a) The two floor pieces together, hand touch the seam height difference; among the selling floor model, you can also conscious of touch, more comparisons. The difference between the brand, should be obvious. b) Second, look closely extent of splicing gap. Little floor has scoliosis, patchwork will not be very tight. This reflects the floor machining accuracy.
