Description
Technical field
The invention belongs to corrosion and protection fields, and in particular to a kind of to wash away the compound painting in environment for the high chlorine height of high temperature
Layer preparation method.
Technical background
Severe corrosive environment, such as chlorine corrosion, high temperature oxygen burn into erosion corrosion are often met in Chemical Manufacture,
Publication is directed to the wherein corrosion of some or several aspects respectively and has carried out means of defence application, but rare method can be right
All of above etching problem solves simultaneously, especially in the environment of high temperature gas that chlorinity is high and has more solid particulate matter,
Chlorine device such as is prepared in HCl catalysis oxidation and is burned in the burning furnace gases burning facility high containing chlorine element.The former is by HCl
The device of chlorine is oxidized to the catalyst of fluidisation state under the high temperature conditions, the latter is to burn the high solid waste of chlorinity or useless
Liquid, such as the incinerator of chlorobenzene, PVC, chlorinity and oxygen content are higher, and contain certain catalyst granules and flying dust etc..
The etching problem of such device is the key factor of confining device long-period stable operation.
The high activity of chlorine makes it that can almost react under the high temperature conditions with all metals, while chlorine improves
Partial pressure of oxygen needed for forming protective oxide film reduces its effective adhesion so that oxidation film cracks and becomes loose porous
And protectiveness.When containing metal chloride in system, it also occur that the corrosion process of " active oxidation ", such as 2Cl-+Cr2O3+O2=
2CrO4 2-+Cl2, partial deactivation film can be dissolved under chloride high temperature, and be diffused into base, it is anti-with the generations such as Fe, Ni therein
Chloride should be generated, the chloride boiling point of generation is lower, and the volatilization of meeting outer layers, can react generation in partial pressure of oxygen eminence again under high temperature
Oxide, the oxide compacting generated at this time is poor, and the stress that volume change generates causes to crack and fall off.
Be boiler of power plant " four pipe " corrosive environment similar in this corrosive environment, it is special applied to the corrosion protection under this environment
Benefit report is more, if CN103060737A discloses a kind of powder cored filament material of nanostructure-containing high temperature oxidation corrosion resistance coatings,
