The market is full of all kinds of various kinds of floors, and the quality is uneven. Good floor is like a beautiful person, beauty is like a cloud in the moon. As an ordinary consumer who doesn't know much about the flooring industry, I really don't know where to choose a laminate flooring. Here I teach you four tricks to see the moon.
First, look at the suit
The color of the selected laminate flooring mainly depends on its color, pattern, and finish. It has the feeling of solid wood flooring, and the balance of the back moisture barrier must be thick. As an alternative to solid wood flooring, the surface of the reinforced composite wood flooring is made of natural solid wood, and the color is gorgeous and natural. The fly in the ointment is that due to the lack of product technology, most of the laminate flooring has more or less false problems. So the standard of choosing the color is the more natural the better.
Second, select the substrate
This step is the most important. Choosing the floor is actually choosing the substrate. Reinforced composite wood flooring on the market is generally composed of four layers of composite materials, namely wear layer, decorative layer, substrate layer and moisture barrier layer. The floor substrate accounts for more than 90% of the entire floor component (in terms of solids), and the substrate accounts for approximately 70% of the cost structure of the entire laminate flooring.
Select the substrate mainly to see three points:
First, the density is good. The density of the substrate affects the physical and mechanical properties of the product and directly affects the quality of the floor. The density of the floor is required to be ≥0.80g/cm3 in the national standard. For example, the substrate of the iconic floor is very tight, solid, and white in color, the same color as wood, which means less impurities. Test method: Look - first look at the fineness of the substrate fiber, whether it is uniform, with or without impurities; secondly, its color.
Second, the water absorption thickness expansion rate is low. The water absorption thickness expansion rate reflects the moisture resistance of the product. The lower the index, the better the moisture resistance. In the current national standard for laminate flooring, the water absorption thickness expansion rate requirement is ≤2.5% (excellent product). Test method: boil - can be placed in the same container with different flooring brands, soaked in water at 100 ° C for 30 minutes, when taken out, the higher the expansion coefficient, the lower the quality, the lower the expansion coefficient, the better the quality.
The amount of triformaldehyde released is low. The amount of formaldehyde released is the key to whether the floor is environmentally friendly. There is a trace amount of free formaldehyde in the floor substrate and the surface layer. The good floor is subjected to dealdehyde treatment, which can degrade the free formaldehyde which is harmful to human health in the floor raw materials, and the formaldehyde emission of the treated substrate reaches the national standard. China's floor formaldehyde emission standard is ≤0.5mg / L. In the field of deacetalization, São Paulo's new E0 floor is one of the best. It uses a durable and environmentally friendly water-washed white core low aldehyde substrate. After deacetalization, the amount of formaldehyde released is reduced by 2/3 based on national standards. Test method: smell - the substrate has no odor.
Several notable features of inferior substrates: low density - usually less than 0.80g / cm3; rough surface; stratification in the middle; burrs at the tongue and tongue; and low strength.
In addition, choose the lock floor
The advantages of the lock floor: the lock floor paving is easier, the seams are tighter, and the overall paving effect is good.
The lock floor replaces the manual paving standard with industry standards, reducing the error of manual paving. Due to the locking force of the lock floor, the floor generally extends to the periphery with the change of temperature, avoiding local uplift, solving the problem of internal deformation of the floor, and the overall paving effect is good. There are single lock buckles, double lock buckles and three lock buckles on the market floor. The single-lock buckles of brand-name manufacturers are generally thick. The double lock buckles and the three lock buckles are generally thin and fragile, so they are still menu locks. The floor of the buckle is better. Test method: dripping water at the joint of the floor, after standing for a while, the water is wiped dry and the two floors are separated. It is found that there is almost no water seepage in the lock, and the lock is tightly connected, and the moisture resistance of the floor is also indicated. Very good.
Finally, choose "three guarantees"
The company that produces high-quality composite flooring has a large scale, and the after-sales service system is perfect. The address and telephone number of the factory on the packaging are clearly marked. The manufacturer's warranty is applied to the product. There are quality problems in the normal use process. package". There are no "three guarantees" for inferior laminate flooring.
Consumers are often blinded by the various certificates presented by the merchants. The certificates placed in many merchant stores are “customers come and put them down,†and it is not enough. The most important certificates are roughly the following: IS09001 quality management system, IS014001 environmental management system certification and China ring mark product certificate. For the former, the certification body is different, and the gold content is also different. The more famous ones are German TUV and Swiss SGS, China Great Wall and Fangyuan. Therefore, consumers must be careful when looking at the certificate, don't be fooled.
