How to judge the arch of the floor and color difference?

Home decoration requires ground decoration materials. We use a dark brown tantalizing solid wood floorboard. After selection, please lay a paving job for the factory's paving workers. When the pavement inspection is accepted, the flatness and sealability are very satisfactory. Dissatisfied, among them, there are more than 10 floors with great differences in the depth of the board surface. We then put forward opinions to ask whether the floor the factory gave us is secondary board. The factory insists that it is a first floor, color difference level country There is no provision, we are helpless, we can only look for it, but after using it for more than a month, we find that other rooms are in good condition. That is, in the middle of the living room, we begin to have some arches, and after a few days, we get more and more arches. On the phone, please call the factory to deal with it. At the same time, we also write to the newspaper to consult and consult:

(1) Why is the reason why the middle of the living room is arched and other parts are not arched?

(2) By the way, what is the reason for the depth of the floor? Does it mean that there is no requirement for the content of the national standard as stated by the factory?

Two questions about the answer are as follows:

1, the reasons for the arching of the floor are many

The first reason: due to improper use of the floor, the faucet or heating of the kitchen or toilet runs out of water, causing the floor to stay in water for too long, and the floor is subject to moisture expansion and deformation, which can only be arched due to the expansion of the swelling size.

The second reason is that when the floor is laid, it is too strict and tight, and the floor is too tight to be expanded with the humidity and humidity, and can only be arched;

The third reason is that when the floor is laid, it should be laid against the wall, and a gap of 2cm should be left as a joint. Then it should be covered with footboards. Some consumers should keep the joints as thin as possible even if they are clean. Small pieces of wood, so that the floor can not stretch, only arch!

The above three reasons, because I was not on the scene, your situation belongs to which kind, I am very difficult to judge, you can only judge!

2, color problem

The cause of the color difference: After each tree is cut, the bark is removed, and macroscopically, the main features of its structure are: sapwood and heartwood; annual rings, earlywood and latewood; ducts and tube holes...etc. Among them, the shades of hearts and sapwood of a great part of wood species are obviously different, and the colors of late wood are also different. Therefore, the color difference is a natural structure of wood and is a natural color. For this reason, the floorboards exported to Europe and Japan are They deliberately want to be color-coded, to be scabbed, so as to show the true nature of nature. This is a different style of pursuit. Due to the different pursuit of style, some colors on the surface of the laminate flooring are deliberately made to have a depth and scab, which makes it more natural.

However, as paving workers should pay attention when laying, according to different consumer requirements, if you like the color evenly, you should pick before laying, paving the wood floor with similar color difference, laying the floor of large color difference Under the furniture or on the side of the shop, so that you can meet the different requirements of consumers. Chromatic aberration does not have special requirements in the upcoming new standards
