Core Tip: There are four most critical test indicators for laminate flooring: formaldehyde release, surface abrasion resistance, water absorption thickness expansion and floor geometry. Determination of formaldehyde emission: Select a large-mouth bottle with good sealing performance, saw a sample of several alternative brands of the same size, put them into different bottles, seal them for 24 hours, open the bottles and smell them one by one.
The most critical test indicators for laminate flooring are four: formaldehyde release, surface wear resistance, water absorption thickness expansion and floor geometry.
1. Determination of formaldehyde emission: use a large-mouth bottle with good sealing performance, saw a sample of several alternative brands of the same size, put them into different bottles, seal them for 24 hours, open the bottles, and smell them one by one, you will compare Out, which brand of floor formaldehyde emission is small. If you are afraid of inaccuracy, you can have two people, have heard and listened.
2, surface wear resistance: with 180 sandpaper (sand paper thickness, the problem is not big), the same person, with the same strength and method, continuously rubbing the same place back and forth, 50 times. Floors without Al2O3 are likely to be severely damaged. 46 grams of wear-resistant paper flooring, the surface will not have serious scratches; 38 grams or less of wear-resistant paper, the surface will have different degrees of wear.
3, water absorption thickness expansion rate: the alternative model of the sawing size approximation, after the number, put into boiling water, 5-8 minutes. Take it out and compare the degree of expansion of their edges. It is best to use a micrometer to measure the thickness of the sample point of the sample and mark it. After soaking in boiling water, take out and measure the thickness, you can calculate the relative water absorption thickness expansion ratio of the floor after soaking in boiling water.
4, the geometrical dimensions of the floor: this comparison test needs to use a whole board for comparison.
a) Put the two pieces together and touch the height difference of the joints by hand; in the model of selling the floor, you can also consciously touch and compare. The difference between brands should be obvious.
b) Next, look at the rigor of the splicing gap. A little bit of the floor has a side bend, and the seam will not be very tight. This reflects the processing accuracy of the floor.
