As a new type of building materials, laminate flooring has gradually entered the living space of the people in recent years, and is increasingly popular with consumers because of its reasonable price, wear resistance and easy maintenance.
But for the laminate flooring itself, most consumers still don't know much about it. In fact, the fineness and occlusion of the concave-convex groove is the most reflective of the manufacturing process and technical level of the laminate flooring, and is one of the key elements that best reflect the quality of the laminate flooring.
Laminate flooring is divided into two types from the occlusion method: flat mouth and tongue. At present, the tongue and groove are the most used, that is, the groove is wedged, which is not only easy to install, but also prevents deformation of the floor. The floor of the tongue-and-mouth is seemingly simple, but it is very knowledgeable. The die-cutting of the groove is not perfect or the adhesion is insufficient, which will affect the service life of the floor.
To select the floor, firstly, it is necessary to observe whether the convex groove die cutting is regular, fine and uniform, and its precision reflects whether the manufacturing process is advanced; secondly, it depends on whether the notch, that is, the protruding portion of the convex groove and the concave portion of the groove have sufficient length. In general, a bit longer bite will be firmer.
The traditional floor groove groove is loose and wide, and it is only glued by glue. There is no problem after installation. However, after the weight of the floor is stressed, the convex groove continuously sways in the groove, the glue is separated from the floor, and a gap occurs in the floor interface. Once the gap enters the water, the floor expands and rises, greatly shortening the normal service life of the floor.
To check the degree of bite of the floor groove, there is a simple and easy way: assemble the two floors without applying glue. Pick up one of them. If the other piece is quickly disengaged, the convex groove is not tight enough. On the contrary, if the other piece is not detached or difficult to disengage, the convex groove of the floor is tightly engaged, so that the floor can be purchased with confidence. In general, the substrate with the convex groove and the tightly reinforced floor is better in quality and higher in strength.
