Color stainless steel tube In recent years, it is more and more widely used

At present, a large number of colored stainless steel products are used for decoration in foreign buildings, and color stainless steel pipes have become popular for a time. Wiq industrial design. Chinese color stainless steel not only has the unique luster and strength of metal, but also has a variety of colors, lasting color. The color stainless steel pipe not only keeps the physical, chemical and mechanical properties of primary stainless steel, but also has stronger corrosion resistance than primary stainless steel. Therefore, since it came out in 1970s, it has been widely used in building materials, chemical industry, automobile, electronic industry and arts and crafts

Among the common primary color stainless steels, austenitic stainless steel is the most suitable coloring material, which can obtain satisfactory color appearance. The former is less likely to get colored in the solution than in the ferrite. However, the low chromium high carbon martensitic stainless steel can only get gray color or black surface because of its poor corrosion resistance. It is reported that austenitic stainless steel has been exposed to industrial atmosphere for 6 years, exposed to marine atmosphere for 1.5 years, immersed in boiling water for 28 days, or heated to about 300 ℃, the color luster of austenitic stainless steel does not change. In addition, it can also withstand general die pressing, drawing and bending, as well as work hardening. At present, color stainless steel can be used in many other fields besides building wall and window frame decoration. For example, black stainless steel tube can be used to make solar collector tube, and the selective heat absorption rate can reach 91% - 93%. In the field of Arts and crafts, the combination of color stainless steel and printing, etching and grinding, and dot method can be used to produce three-dimensional relief murals and hanging screens that will never fade. In addition, the use of color stainless steel to make household appliances, cooking utensils, kitchen equipment, toilet appliances, will be deeply loved by consumers.

Now the color stainless steel tube is gorgeous, is a kind of very good decoration material, uses it to decorate displays the glorious quality, the color stainless steel tube simultaneously has the strong corrosion resistance, the mechanical performance is high, the color surface layer durable does not fade, the color will produce the color change with the illumination angle and so on. The color stainless steel tube and the color surface layer can withstand the temperature of 200 ℃ and salt fog The corrosion resistance of color stainless steel tube is better than that of ordinary stainless steel. The wear resistance and scratch resistance of color stainless steel tube are equivalent to that of gold foil coating. The color layer of colored stainless steel pipe will not be damaged when it is bent at 90 ℃. It can be used for decoration of hall wall pipe, ceiling pipe, elevator car pipe, car trunk pipe, architectural decoration, signboard, etc. generally, color stainless steel pipe is used for wall decoration.

Now some commercial buildings are using the colored stainless steel tube. Such as: the overall decoration project of the office building of Guangzhou Commercial Bank, the high-grade glass stair guardrail of Binzhou Transportation Bureau, the stainless steel glass door of Shandong gymnasium, the stair guardrail project of Fujian anying financial management, the storefront project of Jindeli chain store, some stainless steel projects of provincial hospital, the advertising station board of South Industrial Road, stainless steel cabinet, colored stainless steel cabinet, stainless steel bathroom cabinet, etc.

Classification by different surface processes

Mirror tube (8K), drawing tube (LH), frosted tube, and textured tube, sandblasting tube, etch tube, embossed tube, composite tube (combined tube)

1. Color stainless steel mirror tube

8K tube, also known as mirror tube, is polished on stainless steel tube surface with grinding fluid through polishing equipment to make the tube surface luminosity as clear as mirror, and then electroplating and coloring

2. Colored stainless steel drawing pipe

The cable tube (LH), also known as the hair line, because the lines like hair, slender and straight. Its surface is like a silk texture, which is a processing technology of stainless steel. The surface is matte. If you look at it carefully, there is a trace of texture on it, but you can't touch it. It's more wear-resistant than the normal bright stainless steel, and it looks better. There are many kinds of patterns in hair tube, such as HL, No4, random, cross and cross. All the lines are processed by oil polishing machine, and then electroplated

3. Color stainless steel sandblasting pipe

Zirconium beads used for sandblasting pipe are processed on stainless steel pipe surface by mechanical equipment, which makes the pipe surface present fine bead sand surface, forming a unique decorative effect. Then plating and coloring

4. Color stainless steel combination process pipe

According to the process requirements, the polishing hairline, coating, etching, sandblasting and other processes are concentrated on the same pipe surface for combined processing. Then plating and coloring

5. Color stainless steel and rifled tube

From a distance, the sand pattern of the He Wen (random pattern) tube is composed of a circle of sand lines, and the nearby one is irregular random pattern, which is formed by the irregular swing of the grinding head up and down, and then electroplating and coloring. Whether it is with the corrugated tube, or drawing pipe, etc. are one of the frosted pipes, but the surface state of these pipes is different, so the statement is not the same.

6. Color stainless steel etching tube

Etching tube is in the mirror tube, wire drawing pipe, sandblasting pipe as the bottom pipe, the surface of which is etched out of various patterns and patterns by chemical methods, and then deep processing is carried out; various complex processes such as blending pattern, wire drawing, inlaying gold, titanium gold and other complex processes are carried out on the etched tube, so as to achieve the effect of alternating light and dark patterns and gorgeous colors.

Calculation method of color stainless steel

Color stainless steel price = thickness (mm) x width (m) x Length (m) x density (stainless steel material) x price (yuan / kg) + (processing fee)

Color stainless steel density

Density of "400" series: 7.75

The density of 304, 321, 304L, 202, 201 was 7.93

The density of 310S, 309S, 316L and 316 was 7.98

Classification by coloring process

A. Electroplating

Electroplating: the process of attaching a layer of metal film to the surface of metal or other materials by electrolysis. It can prevent corrosion, improve wear resistance, electrical conductivity, reflective property and improve the appearance.

B. Water plating

In the aqueous solution, it does not depend on the external power supply, but relies on the reducing agent in the plating bath for chemical reduction reaction, so that metal ions are continuously reduced on the autocatalytic surface to form a metal coating.

C. Fluorocarbon paint

It refers to the coating with fluororesin as the main film forming material, also known as fluorocarbon paint, fluorocarbon coating and fluororesin coating

D. Painting

Spray different colors of the coating on the stainless steel tube.

Process editing

The technological process of color stainless steel tube is as follows:

Connect the plated metal to the positive electrode

The object to be electroplated is connected to the negative pole

The positive and negative electrodes are connected by an electrolyte solution consisting of positive ions of the plated metal

The positive ions in the solution are reduced to atoms at the negative electrode and accumulate on the surface of the negative electrode.

On the contrary, the less beautiful the electroplated parts will be.

The main uses of electroplating include the prevention of metal oxidation (such as corrosion) and decoration.

Electroplating principle editor

The process of plating a thin layer of other metals or alloys on the surface of some metals by electrolysis. During electroplating, the coating metal is used as anode, which is oxidized into positive ions and enters the electroplating solution; the metal products to be plated are used as cathode, and the cations of the coating metal are reduced to form the coating on the metal surface. In order to eliminate the interference of other cations and make the coating uniform and firm, it is necessary to use the solution containing metal cations as plating solution to keep the concentration of metal cations unchanged. The purpose of electroplating is to deposit a metal coating on the substrate to change the surface properties or dimensions of the substrate. Electroplating can enhance the corrosion resistance of the metal (the coating metal mostly adopts corrosion-resistant metal), increase the hardness, prevent wear, improve the conductivity, lubrication, heat resistance, and beautiful surface.
