Stainless steel plate pasted on the wall

There are many ways to install the stainless steel plate on the wall according to the process requirements, installation purpose and construction cost requirements. The most commonly used methods are to fix the stainless steel plate directly with expansion bolts and drill holes on the wall with an impact drill, to paste the stainless steel plate with special glue, to fix the stainless steel plate with special glue, to deal with the foundation, to install the frame, and then to install the stainless steel plate. This method should be more appropriate. Do a good job of wall treatment before installation. Before the installation, the wall and the interior of the wall in the installation area should be well treated. The water and electricity pipelines in the wall should be installed according to the scheme, and the relevant pressure pipes have been tested and meet the requirements. The wall has been leveled, and the wall should be dry, with the corresponding construction conditions. Get ready for marking. According to the specific construction scheme and requirements, according to the height and width of the floor, the elevation of the wall is treated, the height is measured with a box ruler, and the wall is graded and marked. This is the "snapping line" construction step in the construction. The specific marking should be very careful, and the marking is clear. This step determines whether the stainless steel plate installation is smooth, whether the gap between the plates is appropriate, and has a great influence on the whole construction The quality of construction has an important impact. Install the keel. After marking, the installation of keel will begin. Here is a simple popularization of what is the keel, keel is used to support the wall shape, fixed structure of a building material, is a very common skeleton used in decoration. The keel installation shall be carried out in general order, from suspender, large keel, small keel, layering, etc. during the construction, attention shall be paid to the accurate installation according to the marking line, the connection shall be firmly fixed with bolts and screws, and the spacing between each other shall be set aside according to the routine, so as to facilitate the installation of stainless steel plate. Do antirust treatment well.

The keel should be made of metal material, which is generally placed on the wall, and the panel should be buckled on it. It will be oxidized and rusted for a long time, which will affect the safety of the material. Therefore, after installation, rust removal should be carried out. The key point is to brush antirust paint on the surface of welding joint, such as connecting point, fixed point, etc. before the next process, and do the relevant treatment well. Install the stainless steel plate. Before installing the stainless steel plate, it is necessary to check and accept the early construction to ensure that the construction technology is qualified, because after installing the stainless steel plate, the early construction is covered, so it is not convenient to check and accept again. After the acceptance, the installation of stainless steel plate shall be started. If it is a whole steel plate, it shall be installed directly and sealed and pressed with a strip. If it is multiple steel plates, it is necessary to install one plate, seal one plate with a strip, and ensure the straight installation along the keel marking line.

matters needing attention

In the process of installation, it is necessary to pay attention to the construction in strict accordance with the operation specifications. When installing, it should be handled with care to avoid deformation and damage of relevant parts, do not contact with other hard objects, avoid scratch damage of stainless steel surface, and affect the effect. The stainless steel plate and keel should be firmly buckled, and the corresponding moisture-proof, heat insulation, rust prevention and other treatment should be done.

Partial application of stainless steel plate

The use of 304 stainless steel plate makes it suitable for the roof covering materials. Because this material is easy to form, durable and beautiful, many architects choose stainless steel as the protective layer. 304 as the most widely used stainless steel, heat-resistant steel, food equipment, general equipment, atomic energy industrial equipment.

The corrosion resistance

Do you know that stainless steel is corrosion-resistant? This metal can withstand corrosion, rust, water stains, etc. This also makes the metal ideal for any area where extreme temperatures and pressures are possible.

 

When making stainless steel coil, chromium is added, which combines with oxygen in the air to form a thin film on the metal surface. The film quickly repairs itself when damaged, making the metal resistant to corrosion and rust. The corrosion resistance of stainless steel is further improved by the addition of nickel, titanium and molybdenum.

 

High and low temperature resistance

Some grades are resistant to scaling and maintain high strength at high temperatures, while others exhibit exceptional toughness at low temperatures.

 

Easy to manufacture

Most stainless steels can be easily cut, welded, shaped, machined and manufactured.

 

Strength

The cold work hardening properties of many stainless steels can be used in the design to reduce material thickness, weight and cost. Other stainless steels can also be heat-treated to make high-strength components.

 

Aesthetic appearance

Stainless steel can be used for many surface treatments. It is easy and simple to maintain, resulting in a high-quality, pleasant appearance. One of the main reasons homeowners choose stainless steel for their homes is the appearance of the metal. It is stylish with a classical and modern touch. Fortunately, this metal is not only beautiful, but also powerful.

 

There's no denying that stainless steel just looks good. After all, there's a reason homes with stainless-steel appliances are more popular than homes without them.

 

Health performance

The cleanliness of stainless steel pipe makes it the first choice for hospitals, kitchens, food and pharmaceutical processing equipment. Stainless steel is one of the most hygienic materials and does not support the growth of bacteria and other pathogens. Even better, the stainless steel is easy to clean and maintain, with a gentle wipe with an all-purpose cleaner followed by a quick polish along the texture to make it shine. Because stainless steel has low maintenance costs and is easy to clean, it is ideal for hospitals, kitchens and other places that need cleaning.

 

Life cycle characteristics

Stainless steel is a durable, low maintenance material and is often the cheapest choice in life cycle cost comparisons.

 

With so many different types of metals on the market, it can be confusing to choose the one that is right for your home. But for all the advantages stainless steel has, choosing the right metal is a no-brainer. Not only is stainless steel beautifully streamlined, but the metal is amazingly versatile and cheap. In addition, metals are promoted as easy to form and are a great choice for many projects.

Stainless steel plate since the beginning of the 20th century, has a history of more than 1 century. The stainless steel plate surface is smooth, has higher plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion. It is an alloy steel that does not rust easily, but is not absolutely rust free. Stainless steel plate refers to the atmosphere, steam and water and other weak medium corrosion of steel plate, and acid steel plate is acid, alkali, salt and other chemical corrosion medium corrosion of steel plate. However, we should also understand that stainless steel plates will rust and be corroded.

Rusting

Stainless steel has the ability to resist atmospheric oxidation, that is, the performance of stainless steel, but also has the ability to resist corrosion in the medium containing acid, alkali and salt, that is, corrosion resistance. However, its corrosion resistance depends on the chemical composition of the steel itself, the state of each other, the use conditions and the type of environmental media. But for some reason, this film is constantly destroyed, air or liquid neutralizing oxygen atoms will continue to infiltrate or metal iron atoms continue to precipitate out, forming a relatively loose iron oxide is stainless steel rust. General stainless steel is very easy to rust in the environment of high air humidity, high pH in the air or high pH solution. Of course, the steel smelting process will also affect the corrosion resistance of stainless steel, smelting technology is good, advanced equipment, advanced process, alloy element proportion control is good, the high proportion of impurities removal, billet cooling temperature control is good and not easy to rust, if the surface damage is easy to rust.

 

Corrosion

The corrosion resistance of stainless-steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and the internal organizational structure, the main role is chromium element. Chromium has very high chemical stability, can form a passivation film on the surface of the steel, so that the metal is isolated from the outside world, protect the steel plate from oxidation, increase the corrosion resistance of steel plate. After the destruction of the passivating film, the corrosion resistance decreases. Following are the corrosion conditions:

l  Stainless steel surface deposited with dust containing other metal elements or similar metal particles of the attachment, in the humid air, the attachment and stainless-steel condensate between the two together into a micro battery, triggered an electrochemical reaction, the protective film is damaged, called electrochemical corrosion.

l  Stainless steel surface adhesion of organic juice (such as vegetables, noodle soup, sputum, etc.), in the case of water and oxygen, constitute organic acids, long time is the corrosion of organic acids on the metal surface.

l  Stainless steel surface adhesion contains acid, alkali, salt substances (such as decoration walls of alkali, limestone splashing), causing local corrosion.

l  In the polluted air (such as containing a large amount of sulfide, carbon oxide, nitrogen oxide atmosphere), in case of condensate, the formation of sulfuric acid, nitric acid, acetic acid liquid point, cause chemical corrosion above circumstances can cause the destruction of stainless steel surface protective film caused by corrosion.

 

Stainless steel plate is generally stainless steel plate and acid-proof steel plate. At the beginning of this century, the development of stainless steel plate for the development of modern industry and scientific and technological progress has laid an important material and technical foundation. There are many kinds of stainless steel plates with different performances. Although stainless steel plate has certain safety problems, it is still the first choice of many steels.
