1. In addition to the special ZS ceramic anti-corrosion coating to reduce corrosion, the plate heat exchanger can also extend its service life by other methods, such as reducing the erosion of the medium, perfecting the heat exchanger structure, reducing residual stress, and electrochemical protection. Method, adding corrosion inhibitor, cleaning the heat exchanger unit regularly.
2. Corrosion of the plate is the main corrosion part of the heat exchanger unit. Common local corrosion types include stress corrosion, crevice corrosion, wear corrosion and biological corrosion, under the action of chemical or electrochemical means of the surrounding medium, and often The damage caused by metal in combination with physical, mechanical or biological factors, that is, the destruction of the metal under the action of its environment.
The plate heat exchanger unit is a device that transfers part of the heat of the hot fluid to the cold fluid. Most of it is in a high temperature and corrosive environment, and the structural corrosion phenomenon is very serious. Therefore, it is very important to take precaution measures.

In optical microscopy different filters are used to improve contrast and emphasize specific features based on material properties. This can be achieved with magnifications typically ranging from 2.5 times up to 1,000 times. In materialography, reflected light is the most commonly used type of light optical microscopy. Transmitted optical microscopy is also used, but mainly for mineralogy specimens.
Stereo Optical Microscopy
The stereo microscope is an optical microscope variant, designed for low magnification observation of a specimen, using the light reflected from the specimen surface.
Scanning Electron Microscopy
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a specimen by scanning the specimen surface with a focused beam of electrons. The electrons interact with the atoms in the specimen, producing various signals that can be translated into information about the surface topography and the composition of the specimen.
Transmission Electron Microscopy
Transmission electron microscopy (TEM) uses a beam of electrons transmitted through an ultra-thin specimen and that interacts with the specimen as it passes through it. Generated signals can be translated into various types of information, including information on the type and orientation of individual crystals.
