In common home decoration, the copper art that we usually see is usually imitation copper, not real copper art. Because copper art materials are more expensive than ordinary materials, and imitation of copper is expensive. In duplex buildings, villas, and high-end hotels, bronze staircases and copper furniture are common. Many hotels use copper ladders to improve their grades and make customers more satisfied. In the process of using the copper ladder, many people are more concerned about some issues, such as: will the copper staircase appear green? If so, what causes it? And how to solve it? Do not worry, I am following these questions , to explain to everyone one by one.
How is the bronze staircase?
1, the appearance of eye-catching
Copper stairs, golden appearance, Yi Bo public eye. In times of beauty, the appearance of the stairs is very important. Even the quality and appearance of the stairs are hooked, and the appearance is considered as good quality.
2, temperament even more high-end
The copper staircase looks high-end, and many high-end venues often appear. There are grades, tastes, and many people love the copper staircase.
3, good texture
Excellent appearance and color, using copper as raw material, excellent texture and stability, giving users a sense of security.
4, durable and durable
Compared with stairs made of other materials, the copper ladder is more resistant to dirt and durability and does not require time and effort to maintain it.
5, more power in the winter
In winter, there is a need to eliminate indoor heaters, so that the interior becomes warm, to save electricity to a certain extent.
Do bronze stairs appear green?
One, copper art stairs have patina
Ironwork has been placed in moisture for a long time and is prone to rust. Copper is oxidized to copper oxide (in black). After the action of copper oxide and carbon dioxide, a green substance is prone to appear, that is, "pink green".
Second, how to solve the problems of copper green stair
1, acetic acid wipe
Convert the surface dirt to copper acetate, wipe it with acetic acid, and wipe it again with clean water. The surface of the copper ladder is brighter.
2, concentrated ammonia wipe
The rag was stained with concentrated ammonia and then wiped green, copper oxide, basic copper carbonate were all converted to copper ammonia complex and removed, and the surface was shiny.
3, clean protective agent wipe
Dedicated cleaning protection agent not only cleans the surface, removes the patina, repairs minor scratches, increases the brightness, and provides a protective layer, reducing the number of cleanings.
How to maintain copper staircase
1, moisture-proof
Copper ladders and iron ladders are not suitable for contact with moisture. They are exposed to moist air for prolonged periods. Inadvertently touch water and dry it in time.
2, sun protection
Home should not be exposed to the sun, otherwise it is easy to aging and fade. The copper ladder has no immunity to sunlight and prevents it from being sunburned, otherwise it is prone to problems such as fading.
3, anti-fouling
Like water stains, stained bacteria can cause corrosion or discoloration of copper. In normal use, it was found that the surface of the stairs was stained. Clean immediately and do not wait until it is corroded.
Editor's summary: The above is the quality of the copper art staircase, how to solve the problem of how to solve the patina problem. The clothes should be matched with the corresponding pants, shoes, and jewelry to have a better visual effect. The stairs also need to be matched with the handrail. , pedals, etc. can improve the face value. As a retro-hardened copper ladder, when it comes to handrails, you need to pay extra attention to the effect.
Copper stairs
Paper dyeing process, the object is to dye the role of paper fibers. Mechanism of different Dyes with different pulp, wood is known as basic dyes great affinity, suitable for dyeing pulp lignin content; pulp surface with a strong negative charge, then the Direct Dyes hardly adsorbed ions , with it to reduce the surface charge, the dye near the fiber surface is fixed. Such non-electrostatic adsorption caused, bauxite is commonly used in papermaking dye retention agent, because the majority of paper dyes are anionic, cationic aluminum compound and anionic dye-forming cation may be precipitated and adsorbed on the fiber surface which is to retain this mechanism occurs at pH 4.0-5.2, then the charge density of the aluminum ions is high, the charge is stronger.
Dyes commonly used in the paper coating colored paper, the dye and the paper fibers by covalent bond, ionic bond between, with the key, and molecular hydrogen binding forces, which depends on the color fastness of adhesion strength, exactly in what based combination, depending on the structure of the dye molecule.
