When the surface of the stainless steel pattern plate has dark brown rust, people are quite surprised: they think that "stainless steel pattern plate will not rust, and rust is not stainless steel pattern plate. In fact, it is the lack of stainless steel pattern plate It is a one-sided and incorrect view. The stainless steel checkered plate will also rust under certain standards.
Stainless steel checkered plate has the ability to resist air oxidation, that is, stainless steel, and also has the ability to resist corrosion in substances containing acids, alkalis, and salts, that is, corrosion resistance. But the size of its resistance to corrosion with the chemical constitution of its steel own, mutual state, working conditions and environmental substance type and change. Like 304 steel pipes, in the atmosphere of dry cleansing, absolute good resistant to corrosion is arranged, but it is moved on to riviera, in containing the sea fog of a large amount of salts, will soon get rusty; Therefore, not all stainless steel checkered plates can resist corrosion and rust at any time.
The stainless steel checkered plate is formed by a layer of thin, firm and fine stable chromium-rich oxide film (protective film) on its surface, which prevents oxygen molecules from permeating and re-oxidizing, and obtains corrosion resistance. Once this kind of plastic film is continuously damaged due to various reasons, the oxygen molecules in the gas or liquid will continue to permeate or the iron group molecules in the metal material will continue to separate out, forming loose compounds, and the metal surface will also suffer continuous damage. rust. There are many ways to damage this kind of surface film, and the common ones in daily life are as follows: 1. The deposits on the surface of stainless steel checkered plate contain dust of other rare elements or attachments of dissimilar metal particles. In the gas, the condensed water between the appendage and the stainless steel checkered plate connects the two into a micro-rechargeable battery, causing electrochemical corrosion and serious damage to the protective film, which is called the principle of the original battery.
2. The surface of the stainless steel pattern plate adheres to the organic compound juice, which forms citric acid in the presence of water and oxygen, and citric acid will corrode the metal surface for a long time. 3. There are acid, alkali and salt substances (such as alkali and lime spray on the interior wall) attached to the surface of the stainless steel pattern plate to cause local corrosion. 4. In the air with pollution (air with a lot of sulfates, metal oxides, and chlorine oxides), when it encounters condensed water, it will produce liquid points of hydrochloric acid, sodium cyanide, and acetic acid, causing organic chemical corrosion.
The above conditions can lead to the destruction of the protective film on the surface of the stainless steel pattern plate and cause corrosion. Therefore, in order to ensure that the metal surface is permanently bright and not rusted, it is suggested that the surface of the decorative stainless steel checkered plate must be cleaned frequently to remove attachments and remove external factors that cause rust. There is a kind of 201 and 202 stainless steel checkered plate on the market that is easy to rust in the Haibin area, and is suitable for use in an environment without pollution and gas corrosion. 304 material stainless steel pattern plate should be used in Haibin area, 304 material can resist sea surface corrosion.
The stainless steel pattern plate has the characteristics of anti-slip, anti-rust and anti-corrosion and is durable. Both are CNC punching machines. The surface treatment process is divided into cold spray galvanizing, hot dip galvanizing and spraying electrostatic spraying. Hot-dip galvanizing is the preferred processing method, because the products after hot-dip galvanizing have strong anti-corrosion ability, can be used in a wide range of environments, and can be used for technical service platforms, construction skids, urban roads, etc. . The stainless steel checkered plate also needs daily maintenance to prolong the service life. Jiangsu Tisco Tianguan Metal Products Co., Ltd. recommends that you consider the actual application scenarios of stainless steel checkered plates and choose the correct use of stainless steel checkered plates.
