Method 1: with the knife to the floor of the sample veneer damage,cut out the inside of the substrate. economical ideas decorative deck panels Color should be wood color, Taibai is rinsed, too dark, then there is too much impurities. What is the color of the wood color? But also as a floor substrate type of flooring is already a lot, and the color difference is also great, there are white and black in the end to that extent, it simply can not be used as a basis for distinction between good and bad basis. Method 2: on the floor substrate tax, place a period of time, if some of the substrate suction finished water, while others remain unchanged, indicating that the water droplets remain unchanged substrate density, and soon absorbent texture loose. In this case, Method 3: different floor soaking in water, look after the color change, outdoor dance floor build planthe color change shows a lot of magazines, the quality is not very good. Because the substrate of different species, so the color will be different, the North with deciduous wood as the substrate, the color will be darker, the south with pine, the color is shallow, so this method does not hold. Method 4: Some samples will be immersed after sink at the end, extending insulated deck over slope indicating too absorbent, and the quality is not good! This really can explain the floor more absorbent, but depends on the floor of the composite index, in other indicators of the same circumstances, low formaldehyde flooring, water resistance but poor, on the contrary, formaldehyde content of water resistance is also slightly stronger . Method 5: the floor sample into a sawdust, add hot water, if you can smell the smell of a strong stimulus that the floor of the formaldehyde exceeded, smell the smell of wood is environmentally friendly flooring. This flavor may indeed be formaldehyde, but everything is based on quality inspection report shall prevail! Method 6: with a hard object in the sample floor, draw a few more times, there is no obvious traces of the floor surface, so the floor is very wearable, the use of time will be a long time. This only shows that the density of the substrate, but can not explain the other pass. Marine seaside waterproof durable composite WPC decking This experiment in the same level of comparison between the product to do experiments, and the strength to be the same, so as to illustrate the problem! Method 7: to the next floor of the pouring water, no water infiltration, and open the floor, there is no water traces, so that the floor water is good. This can only prove to some extent, the water resistance of the floor is good, if the floor contact with water, and soon absorb water, swelling and even deformation, it shows that the water resistance is relatively poor. But it must be in the same level of the product can be comparable, the results have value. Also, the environmental protection of high-grade flooring, poor water resistance, because the laminate flooring substrate in the glue when the use of formaldehyde, the amount will affect the density of the product, the more the greater the density, but water resistance is good . In this case, In fact, in the installation, use and maintenance time is also essential, be sure to do moisture! And the indoor humidity to be controlled at between 50 to 80%, to prevent the deformation of the floor, cleaning does not use dripping mop!
