Commonly used stainless steel industrial plate cleaning methods mainly include physical cleaning, electronic cleaning, electrostatic cleaning and chemical cleaning. Let’s take a look at how these cleaning methods work.
1. Physical cleaning methods
This method uses hand tools and machinery to apply external force to remove various dirt on the stainless steel industrial plate without changing the cleaning method of dirt components. In other words, this is a method that does not change the original chemical molecular composition of dirt. There are mainly mechanical cleaning methods, cleaner and scraper cleaning methods, drill pipe cleaning methods and shot blasting methods.
2. Electronic cleaning method
The principle of this kind of stainless steel industrial plate descaling is to use high-frequency electric field to change the molecular structure of water to prevent scale and descaling. When water passes through a high-frequency electric field, its molecular physical structure has changed. The originally associated chain-like macromolecules will be broken down into individual water molecules. The positive and negative ions of the salt in the water are surrounded by a single water molecule, and the movement speed is reduced. The number of effective collisions is reduced, the electrostatic attraction is reduced, and the structure cannot be constructed on the surface of the heated wall tube, so as to achieve the purpose of antifouling.
At the same time, due to the increase of the dipole moment of water molecules, it increases the absorption capacity of the positive and negative ions (scale molecules) of the salt, which makes the scale on the heating surface or tube wall soft and easy to fall off, achieving a descaling effect.
3. Static electricity anti-scaling method
The descaling principle of this stainless steel industrial plate is the same as the principle of electronic descaling. The purpose of anti-scaling and descaling is achieved by changing the state of water molecules, but the latter uses the effect of an electrostatic field to replace electrons. The specific mechanism is to use the polarity of water molecules (also called dipoles). When the water dipoles pass through the electrostatic field, each water dipole will be arranged in positive and negative order.
If the water in which the stainless steel industrial plate is immersed contains dissolved salts, the positive and negative ions will be surrounded by water dipoles, and they will also be arranged in the water dipole group in positive and negative order. They cannot move on their own and therefore cannot approach the wall of the pipe (device). Then, it deposits on the wall of the pipe (equipment) to form scale. At the same time, the oxygen released into the water will produce a very thin oxide layer on the pipe wall, which can prevent the stainless steel industrial plate from being corroded.
