1. The wear resistance is not as high as possible.
The wear resistance of the floor is a measure of the wear resistance. The national standard stipulates that the household should be used at more than 6000 rpm, and the public places such as shopping malls should be above 9000 rpm.
The level of wear resistance depends on the content of aluminum oxide in the wear-resistant layer of the laminate flooring. If the content of aluminum oxide is high, the wear resistance value obtained during the test is high. While aluminum oxide is a mineral, the content is too high, especially if it is more than 75 g/m2, it lacks toughness, the surface is easy to be brittle, and the clarity of the surface of the decorative layer is also lowered. Therefore, the floor above 6000 rpm is suitable for home use, and more than 9000 rpm is suitable for public use.
Therefore, the wear resistance number is only an indicator to measure the degree of wear resistance of the floor, but it is by no means the higher the better. If the number is too high, it should cause the consumer to be alert.
2. The floor lock is not as good as possible.
The seemingly professional name is actually very life-oriented, as long as consumers pay attention to it, they can understand why. According to Yu Lin, the floor lock is a structure that connects the floor blocks by the physical force of the collapse. The locking force of the buckle mainly depends on the connection between the floor tongue and the tongue. Under normal circumstances, the lock floor can withstand more than 450 kg of pulling force. The lock floor is easy to lay, the seams are tighter, and the overall paving effect is good. Due to the locking force of the lock floor, the floor extends uniformly around the temperature, avoiding local uplift and solving the problem of internal deformation of the floor. Therefore, the quality of the floor lock is critical to the quality of the floor.
Some merchants have added the concept of “double lockâ€, “three locks†and “four locks†to increase the lock level of the publicity. The better the impression. In fact, whether the floor is connected firmly is not in the number of locking stages, but in the chamfering angle and the chamfering area of ​​the locking plate.
The floor manufacturers produced the lock plates initially for the convenience of installation and increased the connection strength of the floor. In the end, it became the increase of the lock level to deceive the consumers. These are the misunderstandings caused by the sales process.
3. Free rubber floor or bearish
“Our floor can be laid without glue, it is a completely rubber-free floor, very environmentally friendly...†I believe this introduction will be heard frequently when consumers buy the floor. In terms of home decoration, people are caught in a misunderstanding of indoor environmental protection, requiring absolute environmental protection. Therefore, "free glue" has become a new selling point for floor traders. The glue-free floor is no need to glue when laying the floor. Because the adhesive will contain a certain amount of formaldehyde, avoiding the use of glue will avoid formaldehyde pollution. In fact, there is absolutely no mistake in theory, but in fact, when the floor is laid, the amount of glue used is small, and the amount of latex is relatively large, and the formaldehyde content does not have much influence on the human body.
Therefore, in the face of the new terminology of the floor, consumers must not blindly believe.
