Environmental protection index
Formaldehyde emission refers to the release of free formaldehyde, which is an environmental protection index. E 1 is generally required.
rub resistance
Usually, the degree of surface wear resistance is 4000 rpm, and the products of general manufacturers will be indicated on the external label.
moisture resistance
The water absorption thickness expansion rate is one of the most important technical indexes of laminated wood flooring. The expansion rate of water absorption thickness is an important factor to determine whether the laminated wood floor is deformed after being wetted. When the water absorption thickness expansion rate is high, the floor moisture-proof ability is poor; The expansion rate of water absorption thickness is low, the deformation of laminated wood floor is small after being wetted, and the product quality is good. Generally speaking, strengthening the floor is usually to try to avoid the use of water.
machining precision
The machining accuracy of the floor is to put two floors together and touch the height difference of the joint by hand; Conscious touch is comparison. The differences between brands should be obvious. Look at the tightness of its splicing gap. If the floor is a little bent, the flat-fell seam will not be tight. Of course, it is important to choose your favorite wood grain and color.
Brand selection
When buying laminate flooring in the market, we should pay attention to choosing products from big brands and historical manufacturers as far as possible, and choosing flooring brands with good service and good reputation is the real worry-free choice. As for many unknown brand products on the market with the trendy slogan of "zero formaldehyde" and "* * antibacterial floor", you don't have to pay attention to them. You can consult relevant people in the industry and understand that these are all propaganda.
