Most of the appearance of the escalator and automatic sidewalk is made of stainless steel. In order to maintain the stainless steel parts of the beautiful and clean, to extend the life of the stainless steel parts, must be correct on the stainless steel surface cleaning and maintenance.

Escalator and autowalk stainless steel parts are mainly floor panels, apron, inside / outside cover plate, handrail frame, cascade and, also according to the special requirements of some customers put forward, sometimes may also use special surface treatment of stainless steel, such as plating color stainless steel, sand blasting stainless steel, stainless steel surface electrophoresis. In this paper, the author introduces the escalator and automatic sidewalk stainless steel parts during installation maintenance maintenance, daily use and maintenance in the use of improper under some special treatment.

1 maintenance of stainless steel parts during installation

In the process of installing the escalator and the automatic sidewalk, avoid touching and pressing stainless steel parts, and can't tear off the protective film.

(1) the escalator and automatic sidewalk stainless steel parts thickness are relatively thin, during transportation and installation must be avoided by collision and extrusion, scratching, or stainless steel parts may will therefore deformation, scratches, affecting the appearance.

(2) the protective film on the surface of the stainless steel should not be torn off by the user before using the escalator and the automatic sidewalk. But the protection of the film will be aging, aging will leave a paste on the surface of the stainless steel plate. Generally speaking, in the packaging protective film under room temperature and humidity performance in a certain period of time effective, however, due to the different specific situations, such as wind and sun, heat, pressure etc., can not guarantee the films to be used within a time limit, so to according to the specific circumstances to determine the tear film, so as not to leave traces of paste. The protective film off, must correctly maintain and clean the surface of stainless steel.

2 daily maintenance of stainless steel parts

To tear off the protective film of stainless steel parts and keep the surface clean. When the surface of the stainless steel parts is contaminated, the correct method should be adopted to clean the surface of the stainless steel.

2.1 different cleaning methods are adopted for different surface contamination states.

Escalators and passenger conveyors in use, due to the different environment, location, the crowd, the pollution state of the surface of the stainless steel components will happen. For all kinds of pollution to take effective measures to maintain the stainless steel parts must be beautiful and clean. The cleaning methods for different pollution cases are as follows: (1) for dust, dirt, minor spots and easy removal of dirt, etc., with a clean wet cloth scrub. (2) to protect the membrane residues, with neutral detergent cleaning wet wipe, degumming use alcohol solvent. (3 > for fats, oils, lubricating oil pollution, with a soft cloth or paper wipe reuse with neutral detergent swabbed with wet cloth. (4) with respect to the bleaching agent and various acid attachments, immediately with a clean wet cloth to erase the foreign body, and then use the containing neutral detergent swabbed with wet cloth.

2.2 attention in the process of cleaning

Stainless steel parts must always be clean, but the use of appropriate tools and cleaning agent must be used, otherwise it may hurt the stainless steel parts. Note: (1) clean please note not to scratch the surface, avoid using containing bleaching composition or abrasive washing liquid, a steel ball (brush roller ball), grinding tools such as dishcloth, be sure to use a soft cloth. (2) at the end of the detergent, need clean wet rag to scrub to remove residual detergents on the surface of stainless steel material, and then dry cloth completely wipe dry. (3) cleaning operation switch components, start and stop key hole should be avoided in the liquid flows through the movable parts.

3 stainless steel rust and other special treatment countermeasures

If because of the use of improper or daily maintenance in a timely manner and do not cause rust stainless steel parts, inform professional maintenance staff, take special measures to deal with, especially rust cleaning of rust parts.

3.1 stainless steel rust reasons

Under normal circumstances, stainless steel is not rusty, but if the use or maintenance of improper or stainless steel in the environment is too bad, stainless steel is likely to appear rusty phenomenon. Because of the composition of stainless steel in addition to iron elements, but also contains other metal elements such as chromium, nickel, titanium, etc.. Chromium, nickel element with anti rust function, it forms a layer of protective film, a thin film, to prevent the stainless steel. In general, as long as the film is not damaged, cracked or contaminated by impurities, stainless steel will not rust. But if the use or maintenance of improper, resulting in the damage of the thin film, stainless steel will be embroidered.

Stainless steel surface rust mainly have the following possible, escalators and automatic sidewalk administrator or maintenance personnel need special attention: (1) of escalators and passenger conveyors in the dust, iron, or easy to rust material environment in. (2) stainless steel parts for long term by water immersion. (3) stainless steel parts are in contact with other strong oxidizing agents such as hydrogen peroxide, potassium permanganate, potassium perchlorate. (4) stainless steel parts are in contact with a strong acid, such as hydrochloric acid, concentrated nitric acid, sulfuric acid, etc.. (5) the stainless steel parts with sodium hydroxide, potassium hydroxide containing strong alkaline substances in contact. (6) there is no regular cleaning of stainless steel parts. (7) the use of the tool or cleaning agent for cleaning the surface of the stainless steel is harmful, such as steel, metal wire brush or scraper, etc..

3.2 the treatment method of rust

In stainless steel to rust, rust can be carried out according to the following steps.

(1) use a soft cloth with a small amount of water to remove dirt from the surface.

(2) the use of stainless steel with special cleaning fluid soft cloth or sponge to remove sticky surface and slight rust.

(3) if rust still can be used for washing tableware cleaning cloth (rough) or steel ball and gently wipe the rust. This step must pay attention to the following items: (1) only for hairline stainless steel mirror and etching on the surface of this operation, must be along the direction of the grain for cleaning rust; (3) if there is residual rust, that place may also can regenerate the rust, so must to thoroughly clean off the rust.

(4) use a damp cloth to scrub detergent containing glass.

(5) use a clean wet cloth to wipe the surface of the stainless steel surface of the detergent and other substances to wipe clean, and then dry cloth to wipe the surface dry.

The surface must be derusted, the maintenance of daily maintenance method in the second section, otherwise it may again rust.

4 stainless steel, stainless steel, stainless steel, stainless steel parts, such as stainless steel parts, such as maintenance of maintenance

Plating color stainless steel, sand blasting stainless steel, surface electrophoresis stainless steel parts of daily maintenance and in Section 2 of the method is similar, but due to the surface coating or paint layer, cleaning must prevent the coating or paint hurt, the cleaning agents and maintenance with the following requirements.

4.1 requirements for cleaning agent composition

(1) must use a neutral detergent or detergent.

(2) not containing an acidic substance, especially the acid containing chlorine or chlorine containing substances, followed by sulfuric acid, sulfuric acid, acid, etc..

(3) the cleaning agent can not contain a particulate abrasive, to prevent the effect of damage to the surface of the board.

(4) prohibited the use of strong acid and alkali detergent.

4.2 cleaning, maintenance considerations

Note: (1) for the cleaning of oil attachments, to avoid the use of organic solvents such as propylene, the day of the organic solution, because they may destroy the surface of the stainless steel coating and paint. (2) avoid contact with substances containing hydrogen peroxide, potassium permanganate, potassium perchlorate and other strong oxidizing agent. (3) avoid contact with strong acid, such as hydrochloric acid, concentrated nitric acid, sulfuric acid, etc.. (4) avoid with sodium hydroxide, potassium hydroxide alkaline substances contact. (5) avoid cleaning, rust remover and other corrosive substances contact. (6) to avoid contact with cement, sand and soot and other pollutants. (7) between the board and the board, in the use of non welded connection, otherwise it will cause local color.

5 Conclusion

Stainless steel is not will not rust, if you do not have to take timely and correct cleaning stainless steel, stainless steel can rust. Since the automatic escalator and automatic sidewalk usually adopt the stainless steel exterior design, it is very important to take timely and correct maintenance of stainless steel components. Only in actual use of stainless steel parts taken correctly and timely maintenance, to ensure the stainless steel parts clean and prolong the service life of the stainless steel parts, escalator and autowalk in appearance and gorgeous and beautiful.
