Acceptance In addition to identifying the overall effect of decoration, the main thing is to see if the quality of the hand is satisfactory. Acceptance can be identified from the following aspects:
1. The laying of lighting circuits shall comply with the regulations. Sockets, lighting switches, main gates, leakage switches, etc. shall have a certain height, kitchens, and air-conditioners shall be laid in dedicated lines. TV antennas and telephone lines shall be installed in positions convenient for maintenance.
2, the drainage should be smooth, no leakage, backflow and water phenomenon, high-grade water parts without clamping and scratch phenomenon.
3. The new masonry wall should be vertical, the bricks must have the same level, the joints should be even and tidy, the brick joints should not exceed 1mm, and the overall tile error should not exceed 0.8cm.
4. It is the overall production error of the plane ceiling that does not exceed 0.5, the crack between the board and the board does not exceed 0.3mm, and the error of the plastic ceiling does not exceed 0.5mm.
5, is the wood sealing line, corner line, waistline veneer meets the seam not exceeding 0.2mm, the line and the line mouth slot joint does not exceed 0.3mm, the veneer and the plate meets does not exceed 0.2mm, the sliding door entire surface error is not Beyond 0.3mm.
6, the paint should be smooth, feel good, no traces of cracks, within a meter no color and nail holes.
7, is the straight line of the wall surface, no significant sense of convexity and color within a meter, used to wipe without dust. The construction quality is related to the quality of the construction team; it is also related to the unit price of the construction project. The best way is to sign a contract between the two parties before the start of construction to clarify the decoration requirements and acceptance criteria.

Black coating is a type of Surface Treatment used to provide a durable, aesthetic and protective finish to metal parts. It is applied to a range of substrates, including steel, aluminum, and titanium, through various processes such as painting, chemical baths or physical deposition.
Black coating provides an attractive, matte finish that reduces glare and reflections. It is commonly used in industries such as automotive, aerospace, and firearms, where aesthetics and durability are essential. The black coating can also be used for functional purposes, such as to reduce friction and wear.
One of the most common types of black coating is black oxide. Black oxide is created through a controlled chemical reaction that forms a layer of black iron oxide on the surface of the metal. This process enhances the corrosion resistance of the substrate and provides a uniform and attractive black finish. Black oxide is also used to provide a matte black finish to gun parts, as well as to increase the conductivity of electrical components.
Another type of black coating is powder coating, which involves applying a dry powder to the surface of the substrate and baking it in an oven. This process creates a durable, weather-resistant finish that is resistant to damage from UV rays and other environmental factors. Powder coating is widely used in the automotive and manufacturing industries, where it provides a long-lasting, high-gloss black finish.
Finally, black coating can also be achieved through physical vapor deposition (PVD). This involves depositing a thin layer of black material onto the substrate through a vacuum chamber. PVD black coatings are very durable, and are often used in high-precision applications such as medical instruments and aerospace components.
In conclusion, black coating is a versatile and effective way to provide a durable, aesthetic, and protective finish to metal parts. Its visual appeal, corrosion resistance, and wear resistance make it a popular choice in a variety of industries and applications. Whether applied through chemical baths or physical vapor deposition, black coating plays an important role in enhancing the performance and longevity of metal parts.
