Three minutes to introduce you to high temperature anti-corrosion coatings

With the development of industry, high temperature operation has gradually penetrated into people's lives

1.

There is no strict temperature limit for high temperature corrosion.

At high temperatures, metal materials undergo chemical or electrochemical reactions with elements such as oxygen, sulfur, carbon, and nitrogen in the environment, resulting in material deterioration or destruction

2.

For example, under the action of oxygen, sulfur and other oxidants, the metal of the water wall of the coal-fired boiler undergoes an oxidation reaction, resulting in high temperature corrosion

The high-temperature corrosion on the water wall of coal-fired boilers is usually sulfide-type high-temperature corrosion, which is mainly caused by H2S gas in the flue gas

Another example: a company that produces sulfur dioxide, the furnace body temperature of its roasting furnace can reach 600 ℃, and there are many corrosive gases.

There are some other similar chemical raw material production furnaces.

It can be seen that if the metal is not protected by high temperature anti-corrosion coatings, its oxidation corrosion rate will be accelerated in a high temperature environment, which will not only affect the appearance, but also lead to the interruption of chemical production, resulting in a lot of waste of resources and costs
.

Therefore, high-temperature anti-corrosion coatings are very important for high-temperature anti-corrosion

Take you to know the high temperature anti-corrosion coating

High temperature anti-corrosion coating refers to a special kind of coating that can well shield the erosion of physical medium, prevent the electrochemical reaction of the medium, and maintain certain physical and chemical properties under high temperature environmental conditions, so that the protected object can function normally in high temperature environment.
Functional coatings
.

It can be divided into organic high temperature anti-corrosion coatings and inorganic high temperature anti-corrosion coatings
.

Among them, organic high-temperature anti-corrosion coatings mostly use silicone as the carrier, and the maximum temperature generally cannot exceed 400 degrees Celsius.
If the temperature exceeds this temperature, carbonization or softening will occur.

.

In contrast, inorganic high-temperature anti-corrosion coatings can withstand a high temperature environment of at least 600 ° C without causing peeling, cracking, discoloration and other defects in the coating, and can achieve good high-temperature anti-corrosion protection effects
.

"Iron-based high-temperature heavy-duty anti-corrosion coating" is one of the high-temperature anti-corrosion coatings series products developed by Anmi Micro Nano.
This series of products are suitable for spraying, brushing, roller coating, dip coating and screen printing processes.
After that, the coating has good adhesion and corrosion resistance, and the adhesion of the coating can reach more than 30Mpa, so that the metal surface coating does not fall off and effectively protects its metal working conditions
.

Not only that, the product also has good high temperature resistance and acid and alkali resistance
.

Under the high temperature environment, the coating will not crack, and the temperature resistance aging exceeds 2000 hours, and it can still maintain good physical and mechanical properties
.

In acid and alkali environments, the product performs well, can easily cope with corrosive environments and keep the coating intact.
It is the first choice for anti-corrosion protection of high-temperature equipment
