1. Controversy about arching.
Many friends abandon the solid wood floor and choose the composite floor because the solid wood floor is easy to arch. In fact, the reference to this question is that there are certain problems. First of all, we must pay attention to an objective problem, that is, many people who are engaged in the decoration industry in the market now have no or no ability to seriously study this problem. In the early days of reform and opening up, quite a few rich families began to make major renovations, but the quality of the decoration team on the market was uneven. The solid wood floor is a arrogant thing, not all can cope. So, it has caused many of these problems. Last week, a company's CEO asked me to talk about the problem of solid wood flooring in his home. The floor was laid at the end of last year. It was already arched when it was not finished, and the people who finished the decoration ran away. It has been repaired three times in April this year. Only one of the phenomena is the arch, and the door can not be opened and closed.
I didn't go to the scene to see it. I simply asked him some things. When I finished listening, I thought about the problem. First of all, at the time, for the sake of beauty, there was no expansion joint for the floor. This problem is obviously a violation of the laws of nature, because anything has more or less thermal expansion and contraction, but it is in the cold weather floor, at that time in a cold contraction, in order to look good and make the seam small, to the hot day Not arching is an impossible thing. Secondly, glue is used in a large amount for the so-called fixing. There are some details of the problem here. If it is a plain board, then it is okay to use white latex or 903 glue. The principle is to let the floor itself absorb moisture and arch it, and then polish it, he will not change anything. If it is a lacquered board, it is recommended that the glue is not used. If it is used, it can only be used with a small amount of 903 glue. Never use white latex. At the time, the decoration company used it to use white latex. Since white latex is a water-based glue, the moisture absorption of the wooden floor must be arched.
If a professional camera is in the hands of a person who doesn't understand the operation, it is not as good as a point-and-shoot camera. But we can't say that professional cameras are not good, right? In fact, the problem of arching of solid wood flooring is due to the operation or the performance of some planks that do not work well. It is not possible to knock down a group of people.
So, what about the arching of the composite floor? I don't think anyone has ever heard of any vendors talking about this issue. In fact, due to the problem of laying the composite floor, although it will not be partially arched, it will be arched as a whole. Because the composite floor does not have a fixed point in the middle of the room, based on the natural law, the composite floor will inevitably have thermal expansion and contraction. Therefore, many composite floors will have a soft feeling when they walk up, which is because they have arched.
2. Disputes about wear resistance.
Now most laminate flooring manufacturers publish their wear resistance data, most of the published figures are as high as 1000 rpm or more (of course, different institutions detect that the number of revolutions is not necessarily the same, some say 5,000 rpm or more And the number of revolutions of solid wood flooring used by these manufacturers is mostly 500 rpm. I believe that any test should be scientific, and any comparison should be objective and should not be comprehensive.
First, the comparison of the number of revolutions should use a product similar to wear resistance. Or, you should choose the strongest of the two sides or the weakest of the two sides. When I was a student, I was always in the wood factory. When I found a piece of wood in the warehouse, it was quite good. I decided to use it as a pair of nunchakus. Later, when I was playing with a younger brother, I took it with a stick. The stick made of stainless steel was flattened. I want to turn around, maybe I can accept it, because the surface of the composite floor is actually more wearable than the solid wood floor.
Followed by the understanding of wear resistance. If it is only the problem of wear on the surface, I think there will be a small problem here. The wear-resistant part of the composite floor is only 0.8% (0.8 mm), while the thickness of the solid wood floor is 18 mm. 14 times. Then, if everyone wears them together, I don’t know who lost them in the end.
Another problem is the problem of edge fracture. Although the surface of the composite floor is quite wear-resistant, its corner is its most vulnerable part. The composite floor is used for a long time, and the first damage is here. Therefore, this kind of wear is conditional, just like the qigong "iron cloth shirt" that we have heard. The mystery lies in the cutting method of cutting the knife. If it is squatting on the front, it is unscathed, but if the knife is in After squatting down and dragging at the same time, then the hacker will be bloody.
