Laminate flooring the most critical test indicators there are four: formaldehyde emission, surface abrasion, thickness swelling and floor geometry.
1. Determination of formaldehyde release:
Selection of good sealing performance big mouth bottle, 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 release small. If the fear is not accurate, can two people, has smell, compare grasp.
2, the surface abrasion:
(Sandpaper thickness, the problem is not), the same person, with the same strength and methods, continuous back and forth friction floor of the same place, 50 times with 180 sandpaper. No aluminum oxide flooring, wood paper is likely to cause serious damage. 46 grams wear-resistant paper floor surface is substantially devoid of serious scratches; 38 grams or less number of grams of wear-resistant paper surface what are disadvantages and advantages of woods and plastics.
3, thickness swelling:
Approximate size sawing 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 a model of the measuring point, make a mark. After water immersion, and then out to measure the 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; between the selling floor model, you can also conscious of interlocking plastic floor suppliers. The difference between the brand, should be obvious. b) Second, look at the rigor of splicing gap. Little floor has scoliosis, patchwork will not be very tight. This reflects the floor machining accuracy.
