The principle of etching or corrosion of stainless steel
using the strong oxidizing property of ferric chloride, the surface of stainless steel is corroded, and the trivalent iron element becomes a relatively stable ferrous element; the specific production process is: firstly apply anti-corrosion on the surface of stainless steel Layer, protect the part to be protected, put it into the flow line of spraying ferric chloride, and wash away the anti-corrosion layer after the corrosion is completed to form a pattern
Below Doris will give you a summary of the steps of the etching process:
Stainless steel plate→degreasing→water washing→drying→screen printing→drying→water immersion→etching pattern leaf (sheet) water washing→ink removal→water washing→polishing→water washing→coloring→washing leaf (sheet) hardening treatment→closed treatment→ Wash leaves (sheets) dry → inspection → product.
Precautions for stainless steel etching
1. Precautions in the process of stainless steel machining
Processing area: The processing area of stainless steel parts should be relatively fixed. The platform of the processing area should take protective measures, such as laying rubber mats. Stainless steel parts should be protected from damage to the surface protection layer of stainless steel parts.
2. the presence of chloride ions in the environment
Chloride ions are widely present, such as salt/sweat/seawater/sea breeze/soil. Stainless steel in the presence of chloride ions, corrosion is very fast, even more than ordinary low carbon steel. Therefore, there is a requirement for the use environment of stainless steel, and it is necessary to wipe frequently to remove dust and keep it clean and dry. (This would give him an "inappropriate use.") There is an example in the United States: a company uses an oak container to hold a solution containing chloride ions that has been used for nearly a hundred years and is scheduled to be replaced in the 1990s. Because the oak material is not modern enough, the container leaks due to corrosion after 16 days of replacement with stainless steel.
3. no solution treatment
The alloying elements are not dissolved in the matrix, resulting in a low content of the matrix microstructure and poor corrosion resistance.
4. natural intergranular corrosion
Such titanium and niobium-free materials have a tendency to intergranular corrosion. The addition of titanium and niobium, together with a stable treatment, can reduce intergranular corrosion. A high-alloy steel that resists corrosion in air or chemically corrosive media. Stainless steel has an aesthetically pleasing surface and good corrosion resistance. It does not require surface treatment such as plating to give full surface properties to stainless steel. It is used in many applications. One of the aspects of steel, commonly referred to as stainless steel. Representative properties include high-alloy steels such as 13 chrome steel and 18-8 chrome nickel steel. From the perspective of metallography, because stainless steel contains chromium and the surface forms a very thin chromium film, this film is isolated from the intrusion of oxygen in the steel to resist corrosion. In order to maintain the corrosion resistance inherent in stainless steel, steel must contain more than 12% chromium. For applications where welding is required, the lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may result in intergranular corrosion of the stainless steel in certain environments.
Production is often done in dusty areas, often with a lot of dust in the air, which constantly land on the surface of the equipment. They can be removed with water or an alkaline solution. However, adhering dust requires high pressure water or steam for cleaning.
In order to prevent the accumulation of process lubricants or products and/or dirt, mechanical cleaning of scratches and other rough surfaces must be performed by a special stainless steel polishing machine. If the stainless steel is heated to a certain high temperature in the air during welding or grinding, the chrome oxide thermal tempering color will appear on both sides of the weld, the lower surface of the weld and the bottom. The thermal tempering color is thinner than the oxidized protective film and is clearly visible. The color depends on the thickness and can be seen in rainbow, blue, purple to pale yellow and brown. Thicker oxides are generally black. It is due to staying at a high temperature or for a long time at a higher degree. When any such oxide layer is present, the chromium content of the metal surface is reduced, resulting in reduced corrosion resistance in these areas. In this case, not only the thermal tempering color and other oxide layers are eliminated, but also the chromium-depleted metal layer underneath them should be cleaned.
7. Rough grinding and machining
Both grinding and machining result in a rough surface with defects such as grooves, overlaps and burrs. Each defect may also damage the metal surface to a depth such that the damaged metal surface cannot be cleaned by pickling, electropolishing or shot blasting (eg dry blasting, abrasive glass beads). Rough surfaces can be the source of corrosion and deposition products. Cleaning weld defects before re-welding or removing excess welds can not be ground with coarse grinding. In the latter case, it should be ground with a fine abrasive.
Application in hotel decoration
Hotel decoration is very different from our general house decoration, because its opening is essentially for profit, so the hotel decoration design must also have an economic concept. In the hotel decoration design concept, so "light decoration, heavy concept" for the decoration principle, by considering the integrity of the entire club, but also consider the economics of the club, as much as possible to achieve the most lucrative return with the least investment . In the decoration design of the hotel, we also need to combine high-end decoration and a small amount of expenses. For a hotel, in the process of decoration, it is even necessary to put the decoration of the hotel in the first place, and the decoration design is only Second.
For a high-end hotel, the service is the service, and the decoration must of course be as unique as possible. Often, many unique decoration methods are more popular with customers. Some iconic representatives may become the unique symbol of your clubhouse. The brand effect of the new city will also bring you economic benefits that cannot be considered. The choice of decorative materials must also be sufficient. If you still think that you want to reflect the gorgeousness and extravagance of the hotel, you must use marble material. Then you really don’t understand these years, decoration. The development of the design industry, the current decorative design industry, is admired a more trendy model. In the selection of materials also know how bold and innovative, there are some new breakthroughs.
The decoration design in the hotel also directly affects the mood of the guests. The beautiful pattern design on the stainless steel etched board can give customers who come here a good mood. At the same time, this kind of plate can create a very good atmosphere. In our daily life, the use of this kind of plate in hotel decoration can often be seen.
In general, in the hotel decoration, the effect we use stainless steel etched plate is to create a gorgeous atmosphere.
