The stainless steel etching technology belongs to a solution for cleaning metal materials, and relates to a composition for removing stainless steel scale and passivating the stainless steel surface. In the production process of stainless steel wire, plate, and pipe, a high temperature heat treatment of 800-1100°C is required, and a very solid oxide skin is formed on the surface after heat treatment.
This technology overcomes the shortcomings in the prior art and provides a low-cost, good-effect, pollution-free stainless steel pickling passivation solution.
In recent years, the application of stainless steel etched plates as building materials is becoming more and more widely used for a variety of reasons, including a better understanding of materials, attempts to update certain designs, and the idea of producing a durable and maintenance-free Structural materials, etc.
Because of the two characteristics of stainless steel etched plates, which are durable and almost maintenance-free, people are paying more attention to their applications than ever before. The prices of most construction materials have increased rapidly in a certain proportion, and many materials have increased their prices. Far more than stainless steel, the cost of maintaining and maintaining the internal and external structure of the building in good condition is even more dramatic. Today's architects must seriously consider the whole situation of the building. If the building needs to be replaced or repaired for many years, then the architect's design fails.
In recent years, the walls of swimming pools have been etched with stainless steel. The main material used for concrete for a long time needs to be repaired and painted every year. Especially in the northern regions, swimming pools constructed with hard steel and coatings also require a large area of scrubbing and Brushing, both of which increase the swimming pool's considerable use expenses. When the swimming pool is made of stainless steel (304 type, 2B finish) as the side wall, the scrubbing is very simple, and it can be cleaned quickly with water and soap. Today's swimming pools often use stainless steel tank walls and concrete bottoms. The concrete in the bottoms is mainly used for anti-skid.
Some building walls use 304 type, grade 8 mirror polished stainless steel as the material. The interconnected stainless steel plates are polished and colored to give the walls a uniform tone and reflection. In order to prevent greasy dirt, the exposed part (velvet foot) of the large-area stainless steel plate is installed in a thick interlayer composed of a galvanized plate and a compressed plate, and the polished stainless steel plate is connected and fixed to the galvanized steel plate with an epoxy resin as an adhesive .
Dry stainless steel can get very soft properties, making it possible to be used as a roof covering material. It is because this material is easy to form, durable and beautiful, so many architects choose stainless steel not only to use it as a protective layer, It is part of the overall design.
Some buildings (indoor skating rinks) use stainless steel materials to build the roof of the Yongping overlapping layer, which not only makes the building beautiful from a design point of view, but also due to the reflective effect of the stainless steel surface, the indoor skating season can be prolonged and relieved. Unreasonable investment.
For some special structures, many problems are often solved due to the application of stainless steel. For example, there is a car garage. The design requires that the parking garage not only has a protective effect on the parked cars but also has a good ventilation effect on the exhaust gas: at the same time, it can also allow a certain degree of sunlight to enter the garage. The material selection is durable and requires no maintenance. According to the requirements, the designer selects 6×10in (15×25cm) 201 stainless steel grid plate, and fixes the grid plate on the vertical column, so that the internal and external staggers cause an overlapping layout. In order to enhance the architectural design effect, the interlaced grid plate adopts floating surface finish , The outer rows of column grids use ordinary 2B finish, and all the grids inside are 2D finishes. This pattern of loan change makes the garage have a vivid appearance.
For the roof structure of a building, its service life and appearance should be equally valued. In the restaurant of the airport, in order to make the roof beautiful, the exhaust fans are covered with stainless steel plates. When choosing a covering material, special emphasis was placed on the non-reflective properties of the material. The selected material is type 304 stainless steel, rough polished, low reflectivity, grade 6 finish. For the choice of finish, special attention should be paid to the glare that hinders the sight of the pilot when landing at the destination.
Stainless steel is used in the internal and external building structure of the office lobby. Its construction measures use stainless steel as the curtain wall, the column columns at the entrance of the building are covered with stainless steel plates, and the purification devices of all windows on the front of the building are also covered with stainless steel.
The ceiling above the lounge of the office building is composed of embossed stainless steel panels. Use male and female dies to punch the embossed parts on the stainless steel sheet.
The stainless steel etched plate not only has a long service life, but also is a good material for making an embossed structure, which can enhance the beautiful shape of the building, so it is often the main symbol of the square.
Another example of the use of stainless steel as the main material for outdoor art buildings is the famous arch bridge that stands on the river.
The stainless steel material can be chosen arbitrarily. It has a variety of different strength-to-weight ratios to meet the requirements of various building structures. In addition, different grades of surface finish also provide a range of choices for various construction facilities to meet actual needs. The architect's bold conception will make stainless steel more and more widely used in the construction industry.
