Remember that these seven tests are known as "one touch," "two," "three," "four," "five," "six," and "seven bubbles." Each step helps you assess the quality of laminate flooring in a different way.
First, the "one touch" test: when you run your hand over a good-quality substrate, it should feel smooth, flat, and slightly grainy. A poor-quality one, on the other hand, feels rough and uneven to the touch.
Second, the "two" test: take the same volume of both substrates and compare their weight. A high-quality floor will be significantly heavier than a low-quality one. This is because better materials are denser and more compact.
Third, the "three" test: look at the cross-section of the flooring. A good product will have a dense, uniform wood structure with no visible impurities or voids. A lower-quality one will appear loose, with dark spots or debris mixed in. After cutting the floor, the cross-section of a quality product should be clean and well-defined.
Fourth, the "four" test: smell the cross-section. A good floor emits a fresh, natural wood scent. A poor one often has a strong, chemical-like odor, which can indicate the use of inferior adhesives or treatments.
Fifth, the "five" test: perform a wear resistance check by gently rubbing the surface with sandpaper about 10 times. If the decorative pattern starts to fade or get damaged, it means the floor doesn't meet national wear resistance standards.
Sixth, the "six" test: examine the joints. Take a random board and check if the edges fit together smoothly without any gaps. If the joint feels uneven or has a noticeable height difference, the quality is likely poor. For solid wood-style floors, pay attention to whether the notch splicing includes a protective wear layer and how easy it is to clean.
Finally, the "seven" test: place a small piece of the floor in a glass jar filled with water. Observe if the water becomes cloudy, thick, or develops an odor. If so, it suggests the floor contains less glue and may not be as durable. Also, check the water absorption thickness expansion rate—lower expansion means better resistance to warping and deformation. The clearer the water remains, the better the quality of the floor.
By following these seven simple tests, you can easily distinguish between high-quality and low-quality laminate flooring. Whether you're buying for your home or for a project, taking the time to evaluate each aspect ensures you make the best choice possible.
Grinding Wheels
Kemei designs, tests, and builds all types
of grinding wheels. The aim of abrasive grinding wheels is to modify the surface structure
and/or preparation of a workpiece. In general, fixed abrasive wheels are
characterized by grit size (abrasive grain), bonding type, substances used, and
the grade and structure of the fine grinding wheel. Users of our wheels can
choose between a specially formulated wheel tailored to their exact needs, or
choose one of our reliable standard specifications. Additionally, the
physical and chemical properties of the diamond and/or CBN crystals can
influence the performance of the grinding wheel. Having over 20 years of
experience in our field has earned us the prestige of manufacturing the highest
quality fixed super abrasive wheels and abrasive grinding wheels. Above all,
being an abrasive wheel manufacturer, allows us to offer you success in your
future projects.
Kemei produce and aim on the following
types grinding tools, such as aluminum oxide grinding wheel, silicon carbide
grinding wheels, mounted points, Diamond Grinding Wheels, CBN Grinding Wheels
and all types of saw blades and cut off wheels.
If you need any type of grinding tool or
