How to choose composite floor?

Polka floor shopping knowledge: look, smell, grind and soak.

First, look-look is to look at the flat seam, look at the appearance and substrate of the floor. When choosing a floor, we should first look at the processing technology of the floor, such as V-groove floor, which is also called anti-chamfering solid wood floor. The V-notch of this floor is printed by color conversion. Look at the color difference first, that is, whether the color is close to the color of the floor, whether the flat-fell seam is tight, and it is easy to seep if it is not tight. There is also a U-shaped trough floor, also known as molded floor. Its processing technology is more advanced and beautiful than V-groove, but it is difficult to process and requires high precision. After looking at the outside, it depends on the substrate. The key to floor quality is the base material. Generally, the base materials selected for good quality floors are all the primary colors of wood, which can be seen clearly without dyeing and waxing. Good base fiber is fine and textured, and the groove edge is smooth and not rough.

Second, odor-odor is a simple method to evaluate the formaldehyde emission from the floor. Just when you buy it, put the slot on the floor under your nose and inhale hard. A good floor smells like wood, and a poor floor smells pungent, indicating that formaldehyde may exceed the standard, so be careful when choosing!

Third, polishing-the wear-resistant revolution of the floor is also an important indicator that everyone cares about. Walking into the reinforced floor sales area of the floor supermarket or building materials store, the slogan of "wear-resistant revolution reaches 10,000 revolutions" can be seen everywhere, but whether the wear-resistant revolution is as high as possible, consumers are also confused. Many consumers are used to changing comfortable slippers when they enter the door, so the degree of wear on the floor is not great, and the reinforced floor with 4000 turns is enough for family use. Of course, wear-resistant revolutions should be considered when buying floors. For example, in a living room or office with a high trampling rate, you can use a floor with more than 4,000 revolutions, but you can't blindly seek "high" in bedrooms, bathrooms, kitchens and other places.

Fourth, soak-that is, soak a piece of floor material in a basin at home for a few hours to see if the expansion coefficient is too large. General floor water absorption thickness expansion rate is less than or equal to 2.5%. It should be noted that the blisters of wood products are all expanding, and the water temperature is also the key. Inexperienced judgment may have errors. This is for reference only!
