Rust removal of gilded utensils
The method of removing rust on gilded objects varied according to the condition of the object. If it is a gilded Buddha statue and the base metal is mixed with copper and green rust appears, acid or hydrogen can be used to remove rust; if the base metal is mixed with iron and red rust appears, it can be removed with sulfuric acid; sometimes it can also be removed by soaking in 2% NaOx solution for a few minutes. There were two ways to deal with the rust on gilded bronze or silverware. One was to use chemical methods, such as using organic amines and biochemical reagents to react with copper ions to remove the rust on the surface of the gilded bronze cultural relics. The organic amines and the biochemical reagents had good chelation ability for copper ions. The chelation constant was stable, the rust removal effect was good, and the bronze body was not corroded. The other method was mainly mechanical, using chemicals to decompose and soften the green rust on the object, and then using hand tools and some small electric machinery to remove the rust layer on the surface of the object. In the process of rust removal, it was also necessary to pay attention to the dust on the surface of the gold-plated objects. Try to avoid repeated scrubbing because the pure gold was very soft, so you could use a soft brush or soft antelope skin to wipe it. If it was difficult to remove it, you could use ether, gasoline, neutral soap foam or 10% hydrogen to clean it, and then wash it repeatedly with distilled water and dry it.

Rust removal agent for camera battery compartment
If the camera battery compartment needs rust removal, consider using WD - 40 rust removal agent. When using it, spray the rust removal agent on a tissue first, then use the tissue to gently wipe the rusted parts of the battery compartment instead of spraying the rust removal agent directly into the battery compartment to avoid unnecessary damage to the camera. However, even if the rust removal operation was carried out, there was no guarantee that the battery compartment related faults (such as poor battery contact) would be resolved. Further inspection and testing of the camera's usage was needed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Rust of Rust
Rust was a mixture of a series of oxides formed by the interaction of iron with water and oxygen in the air. Its main component was iron dioxide (Fe2 O2), and it might also contain iron oxide-iron, iron oxide-iron, and so on. Rust was a reddish-brown solid powder at room temperature. It usually existed in the cubic crystal structure of the corundum-type cubic crystal structure of the crystal form of <anno data-annotation-id ="0000004 - 4444 - 4000 - 9000 - 9000000000">-Fe2 O2 </anno>, and a small part of it existed in the cubic crystal structure of the metastable crystal form of <anno data-annotation-id ="2660000 - 4000 - 4000 - 90000000000">-Fe2 O2 </anno>. It is not dissolved in water, but it is dissolved in sulfuric acid, sulfuric acid, and slightly dissolved in sulfuric acid. Rust was a loose and porous-looking material. This characteristic increased the original surface area of iron, which was conducive to increasing water absorption, thus speeding up the rusting of iron.

The arrangement of kitchen utensils
The kitchen utensils should be placed according to the kitchen's work flow and frequency of use. The most commonly used tools should be placed closest to the console, usually in the cabinet below the console. Dried goods could be placed on the hanging cabinet, while meat and fresh vegetables were usually placed in the refrigerator. The refrigerator and the hanging cabinet for dry goods should be as close as possible. Small tools such as planers and scalers should be placed in the area near the vegetable basin to make it easier to put them back into the vegetable basin after peeling. It was best to place a matching metal basket in the vegetable basin to facilitate draining water. The trash can should be placed under the vegetable basin to facilitate throwing trash. The dishes could be placed on the dish rack, and the bowls could be placed upside down on the rack to allow the dishes to dry naturally. Knives should be placed in a knife box, washed and placed away after use. Cooking utensils such as pots and spatulas should be dried and stored separately after use. The refrigerator should be placed in the kitchen, but not directly opposite the stove. The kitchen plants could be placed according to the location of the kitchen. The kitchen utensils and equipment in each functional room of the kitchen should be placed horizontally and vertically, so as not to hinder the chef's vision. The kitchen utensils had to be placed according to the process, and the working passages and corridors had to be left wide enough to ensure that the kitchen staff could walk back and forth smoothly. In general, the kitchen utensils should be placed in a way that was convenient for the work process, clean and orderly, and in line with the chef's operating habits.
cultural relics and utensils

There were also many cultural relics abroad, such as the Smiling Figure from Mexico in the 6th to 8th centuries, and the hollowed-out human basin unearthed in Shaanxi from 4000 to 3500 B.C. In addition, there was a Derry Iron Pillar built in 415 AD in the Kudub Tower in the southern suburbs of New Delhi, India. It weighed 6.5 tons and was 7.25 meters high. It had almost no rust after thousands of years. The reason why it did not rust was still puzzling to experts. The Antikythera robot, discovered in 1900, had 37 gears inside, exquisite workmanship and mysterious inscriptions. It was considered to be the earliest computer in the world, but its manufacturing principle and other issues had not been solved by archaeologists.

Parrot cups were very popular among alcoholics in the Tang and Song Dynasties. There were parrot cups in Xing Kiln of the Tang Dynasty. Gu was a wine vessel with a large mouth and a retracted bottom. Its capacity was about two liters. Its name probably originated from the similarity with the gourd. The ancients often used the gourd shell to hold wine. The gong first appeared in the middle and late Shang Dynasty, and gradually disappeared in the middle and late Western Zhou Dynasty. The lid was mostly shaped like a beast's head or the whole vessel was in the shape of an animal. Except for a few realistic paintings, most of them were freely created images of monsters. It had the function of holding wine and also carried cultural significance. It was a symbol of power and status and often appeared in the tombs of nobles.

Chang 'an rust
Some Chang 'an cars had rusting problems. For example, the quality of the body materials and the painting process of Chang' an Yuexiang were not up to standard. The body of Chang 'an Yuexiang with an owner began to rust after half a year of use in the humid environment in the south, and the lower edge of the door and the edge of the trunk were rusted. There were rust spots on the hood of the new Changan CCS75 Plus car after one month of purchase. The reason might be the poor quality of the original paint. The body of the Changan Auchan A600 had serious rust and corrosion. After repainting, there were still rust spots, which might be rust from the inside out. The Changan CCS75 also had rust and corrosion in many parts of the body.

The Rust of Photographs
What you want to ask might be "the confusion of photography". There were many problems in photography. For example, novices often had the problem of being too greedy for perfection. They did not think about the composition when shooting, the picture did not highlight the theme, and the elements were messy. In terms of exposure, novices were prone to inaccurate or too stable exposure. To judge whether the exposure was good or bad, it was not only based on whether it was accurate, but also based on the desired tone.(high key, middle key, dark key) to determine the degree of exposure; in composition, many novices like to compose in the middle and lack ideas, and their composition ability needs long-term training to improve; in terms of white balance, even if the camera's white balance is usually accurate, special weather (cloudy, rainy, night) also needs to be adjusted. In photography, there were still some puzzles related to the art of photography itself. For example, photography artists who pursued creativity faced the risk of their works being plagiarized. Their carefully created works might be plagiarized by unscrupulous merchants. Even if they succeeded in defending their rights, it might not be meaningful. Moreover, if they could not give intellectual property protection, economic income security, or respect, they would be in trouble. In terms of improving their photography skills, some photographers were prone to misconceptions, such as thinking that buying a high-quality camera would allow them to take high-quality photos, relying too much on post-processing, and neglecting the core elements of portrait photography in pursuit of good-looking models. Photographers needed to have the ability to find order in disorder, including perception, discernment, and organization. These abilities needed to be cultivated. Many photographers would also be confused in this area, such as how to accurately grasp the timing of shooting, how to find elements worth shooting in ordinary pictures, and how to better organize pictures. In addition, the photography industry also made it easy for photographers to fall into internal friction. They did not know if they had made progress, and they felt anxious in the face of rapid changes in the industry and the need to display more talents. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
