There are two possibilities for the general condition of the tile-like arching of the tile-shaped arching floor of the floor:
One is that before the floor pavement, the moisture content and the equilibrium water content in the local city are not known, and blind splicing is adopted. This is the main reason for the arching of the floor. Part of the reason is that the humidity on the ground is too high. Before doing any moisture treatment, laying the floor causes the floor to become excessively hygroscopic and form a tiled arch. Therefore, in the summer installation, a playing card-sized gap should be reserved.
The second is caused by improper use of consumers. There is a general focus on using untwisted damp cloths to wipe the floor or floor accidentally, resulting in excessive moisture absorption on the floor causing tiled arches.
The contraction of the floor in the southern area is more serious floor contraction, in addition to the air conditioning caused by the air is too dry to cause the floor to contract, the floor contraction has a certain relationship with the product quality, you can immediately contact the manufacturer, and require the manufacturer to produce a quality analysis report. It is a normal phenomenon that the floor shrinks within 2.5 mm of each single piece in the northern area, and more than one part can contact the manufacturer.
Cracking of the floor Many woods can be deformed or cracked in the natural environment or under the conditions of drying. Cracking the wood to make the floor affects its quality level. However, due to improper control of the drying process, internal cracks may be caused and hidden defects may be formed and gradually exposed during use. In general, the humidity of the bottom environment that is in contact with the floor is slightly higher than the floor itself, so the moisture absorption and expansion of the floor cause mutual squeezing and cracking. Some cracks are related to the wood fibers of the material itself and are difficult to avoid. If a large number of floors are cracked on a large area, it may be related to the processing technology. Contact the manufacturer to solve the problem.
The cracking and cracking of the floor paint film is often caused by the dampness of the floor or due to the poor lacquer property of the material, but it is also unrelated to the quality of the paint and the construction process. If this happens, it can be communicated with the manufacturer.

Microscope Slides And Cover Slips
1. The glass slide is used to put the sample to be tested, and the cover glass is covered on the sample to be tested.
2. The glass slide is at the bottom, which is the carrier for the material you want to observe, that is, you want to put something on it.
3. The cover glass is smaller than the slide glass. The glass slide is mainly used to hold the observation objects. The cover glass is covered on the slide glass and used for fixing.
4. The glass slide is a thicker piece of glass in the transfer slide, which is used to carry the real object. The cover fragment is the small round or square thin one.
5. Mounting is a general term for a set of things, including slides, coverslips and loaded objects
6. The cover glass is square, the slide glass is rectangular, and the width is longer than the side of the cover glass.
