Causes of embroidering of channel gates and precautions for maintenance
Abstract: The reasons for the embroidering of the channel gate and the precautions for maintenance.
1. The reason for the rust and pollution of the passage gate
1. When road construction, construction, or various vehicles are walking, they are attached to the scattered earth, sand, dust, iron powder, etc.
2. When it is contaminated by harmful substances such as sulfurous acid gas contained in the exhaust gas of cars, buses, etc.
3. It is polluted by harmful components in the exhaust from dust from various industrial and mining waste incineration, building cooling and heating, etc.
4. It is polluted by corrosive gas generated in the hot spring area.
5. It is polluted by the salt in the coastal sea breeze.
6. Contaminated by cleaning chemicals. Contaminated by hand prints and dirt.
8. Contaminated by the mucous membrane for surface protection.
2. Cleaning methods for various reasons of channel gate rust
1. When rusted by the adhesion of foreign metals
When “incidental rust” is caused by iron powder or the situation is not too serious, the barrier can be easily removed by wiping it with a sponge or cloth, and a neutral detergent or soapy water. Then rinse with clean water, taking care not to leave the lotion on it. For this degree of rust removal, as long as the removal work is done immediately, it is not only easy to maintain, more effective, and the removal cost is also very cheap.
But if you leave it alone, it will soon form a mixture of iron hydroxide, iron oxide, and iron sulfite, and it will appear to be a brownish severe rust state. In this case, it can be completely cleaned up with a commercially available stainless steel cleaning solution for swing gates or a dilution of 15℅ nitric acid. However, there is also rust that cannot be removed, and it will also damage the stainless steel surface or damage the stainless steel. At this time, use sandpaper or a stainless steel brush to rub and wipe, and then clean it with a cleaning solution.
2. Rust caused by adhesion of harmful components in exhaust gas
In the environment of the construction site or the city with heavy traffic, the surface of stainless steel is easily contaminated, and sometimes there will be small spots of rust. These conditions are mostly caused by harmful components contained in exhaust from automobiles, air-conditioners, or factory exhaust. At this time, when the pollution is slight, it can be completely cleaned with neutral detergent or soapy water, but when it is serious, it is not easy to handle. In this case, the same maintenance method as in the previous item 1 can be used to clean it. In this environment, as much as possible 2-3 times a year for comprehensive regular cleaning work, and at least one regular cleaning is absolutely necessary.
3. Rusting caused by attached salt
When the front side is blown by the sea breeze in coastal areas, SUS 304 stainless steel will also produce red rust in a short period of time.
Moreover, it rusts faster than other areas, and the treatment method is the same as in the case of 1.
When using stainless steel exteriors in coastal areas, it is hoped that more corrosion-resistant SUS 316 should be used as stainless steel.
As for the use of SUS 304 for stainless steel exterior, as far as possible, do regular cleaning 3-4 times a year.
4. Rust caused by adhesion of cleaning chemicals
If it cannot be cleaned with a neutral cleaning agent, use a cleaning solution to remove it.
5. Rust caused by hand dirt or fingerprints
If it cannot be cleaned with a neutral detergent, wipe it with a sponge, cloth, etc. moistened with an organic solvent (alcohol, benzine, acetone, etc.). If this method still cannot be completely removed, use a cleaning solution for stainless steel to remove it. In short, after cleaning with various cleaning methods, you must do another rinse with clean water.
6. Pollution caused by surface protective film
Use a sponge, cloth dipped in a water-soluble neutral detergent, or alcohol to wipe. If it is still ineffective, use thinner and light oil to remove it. Rinse thoroughly with clean water after washing.
Three. Attention points in the maintenance of channel gates
1. The reasons and conditions of contamination and rusting of stainless steel building materials are completely different for each situation. Therefore, the most suitable maintenance method should be adopted under various conditions.
2. When using a cleaning solution to remove pollution and rust, please do a local "trial wipe" in advance to confirm the cleaning effect. If the test results are satisfactory, then follow this method to do a comprehensive cleaning. And don't only clean the rusty parts, but also clean the surrounding parts as much as possible. If this is not done, the luster of the stainless steel surface will be uneven and the appearance will be ugly.
3. After using the cleaning chemicals, it must be completely cleaned with clean water. Be careful not to leave the chemicals on the surface of the stainless steel, otherwise it will cause rust. The cleaning liquid can cause roughness or spotted rashes on the hands. So please wear rubber gloves before use.
4. When using cloth, loofah, nylon sponge, brush hook, and brush cleaning tools, it must be cleaned along the stainless steel. If you do a round cleaning, the pollution is not easy to remove, and it will damage the glossy lines on the surface, and it will become ugly.
Steel cleaning tools, such as rough-lined cleaning agents, or the use of sandpaper, although they can remove serious pollution, are absolutely forbidden to use because they will damage the stainless steel surface and attach iron powder to cause rust.
