After reading the following content, you may know how to ask your construction personnel to properly construct it!!! Commonly due to improper construction Misjudgment is a phenomenon of quality problems.

3. During the construction, the joints are treated and scraped with a scraper, which causes the texture on both sides of the joint to be damaged. It is bright when viewed from the side and is mistaken for side shadows. Tip: gentle construction
4. During the construction, the surface of the wallpaper is scraped with a scraper or a hard towel (there are many thread ends), which causes the ink or gold, silver, pearl powder to fall off, and the color fastness of the wallpaper is not enough.
5. During the construction, the hand is not washed, the towel is too dirty, and the dirty things on the wall are exuded from the joints, causing the seams to be black on the side and mistakenly considered to be the side shadows;
6. During the construction, the glue overflowed from the joints, and the sponge was not washed with a large amount of water. The seam on the wall of the wallpaper was yellow after a few days, which was mistaken for quality problems.
7. The hard scraper is used in the construction of gold foil paper, which causes the surface of the gold foil to be damaged or scratched, which is mistaken for quality problems. Tip: The construction tools should be selected for different materials and different parts.
8. When the gold foil paper is applied, the white glue is contaminated on the surface of the gold foil, causing the gold film to lose its luster (the white glue will form a fog film on the surface of the gold film, and it cannot be wiped), which is mistaken for quality problems. Tip: Gold foil paper Very beautiful, but she is also afraid of glue
9. After the wall is brushed through the varnish, the wallpaper is not dried until the varnish is dried, causing the varnish to penetrate into the surface paste from the bottom paper, and a chemical reaction occurs to form a granule-like convex particle, which is mistaken for the quality problem; If it is not dry, it is a big taboo.
10, after the wallpaper is posted, the window is opened immediately, resulting in the drying and shrinking of the wallpaper too fast, forming seams obviously, mistaken for quality problems; Tip: step by step, can not be irritable

The secretion of the mold will chemically react with the paste, resulting in large-scale discoloration of the surface of the wallpaper, erythema or blue spot, and mistaken quality. problem. Because the mold grows in a warm and humid environment, such conditions often occur in the rainy and hot seasons. Generally, there are water pipes arranged in the wall or near the eaves and windows.
Tip: Wall moisture is very important, especially the wallpaper paper of pure paper, non-woven fabrics, etc. should be waterproof. It is recommended to brush a base film on the wall.
Thin wall ball bearings are simple in structure and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of Angular Contact Ball Bearing and can bear combined radial and axial load.
When the speed is high and thrust ball bearings are not suitable, thin wall ball bearings can also be used to bear pure axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for heavy loads.
Thin wall ball bearings have a bearing inner diameter and outer diameter ratio less than a specified value. The ratio of bearing outer diameter to bearing inner diameter is 1.25 or less. It is called thin wall ball bearings, which means that the outer diameter-inner diameter value of the bearing is very small and the bearing wall is very thin.
The precision required by thin wall ball bearings is very high, because the wall is very thin, so the weight it can carry is also very low, and the impact resistance is very poor, so this must be selected according to the use environment!
Characteristics
The specific use of thin wall ball bearings:
Model airplanes, remote control cars, machine tools, motors, water pumps, agricultural machinery, textile machinery, laser printers, instruments, measuring instruments, electronic accessories, motors, motors, etc.
