How much details do you know about catalytic converter coating process?

According to relevant statistics, automobile exhaust accounts for 60%-70% of the total urban air pollution.

In order to control pollution and achieve the specified emission targets, the catalytic converter is also making innovative improvements, as we all know, one of the characteristics of the converter is to coat a layer of material on the honeycomb ceramic carrier, in fact, this process contains many knowledge points.

Uses and applications of catalytic converter coating

Catalytic converter coating is a surface treatment technology widely used in metal industry, which can effectively protect metal products from oxidation, corrosion and other environmental erosion, improve their durability and appearance quality.

Since this technology is suitable for various metal products, the catalytic converter coating technology can be used as an efficient and reliable metal anti-corrosion coating technology in the fields of automobiles, ships, buildings and so on, and play a long-term protection role.

Process details for catalytic converter coating

Converter coating technology usually consists of four steps, namely surface preparation, coating stage, curing and inspection packaging.

Step 1: Preparation before the catalytic converter coating process begins

Before the formal coating, the metal product needs to be cleaned and treated. This includes dirt and rust removal, cleaning and oil removal, and possible pickling to ensure that the paint adheres evenly to the metal surface by improving its roughness and adhesion.

Step 2: Proceed to the coating phase

Catalytic converter coating includes a primer coating and a top coat, in which the primer is a special coating with better adhesion and anti-corrosion ability, which can be applied to the metal surface to provide a uniform base for subsequent top coats. As the outermost layer of the entire coating system, the topcoat has the function of anti-corrosion, aesthetics and protection. By evenly applying the topcoat and applying it several times if needed, a durable, good anti-corrosion protective layer for the metal surface can be formed.

Step 3: curing stage

The purpose of curing is to improve the durability and adhesion of the coating through high-temperature baking, ultraviolet exposure or the use of special curing agents, but the curing time and temperature are dependent on the type of coating and the desired properties, and can be adjusted through experiments and tests.

Step 4: Inspect and pack

After the coating process is complete, we need to conduct a quality inspection of the coating to ensure that it meets the specifications. Common inspection methods include coating thickness measurement, adhesion test, corrosion resistance test, etc. After passing the inspection, the metal products are packaged to protect the coating from external damage and facilitate transportation and storage.

In summary, every link in the catalytic converter coating process is very important and requires strict control and technical support. Only if every detail is handled correctly can catalytic converter coating take advantage of its advantages and provide more lasting and aesthetically pleasing protection for metal products.

Application of coating technology in GRWA catalytic converter

We all know that the catalytic effect of the catalytic converter will react under certain temperature conditions, the general ignition temperature is about 300 ° C, but the catalytic converter can not reach the ignition temperature of the catalyst when it is cold started, coupled with the temperature difference in the heated area, which will lead to pollutants in the tail gas can not be converted into the atmosphere.

Therefore, the catalytic layer of the GRWA catalytic converter adopts an integral coating structure, that is, the catalyst layer is uniformly coated on the carrier material, which increases the specific surface area of the carrier and makes the catalytic reaction more thorough.

GRWA's catalytic converter has EPA certification, long-term export to the United States, Australia and other countries, fully meet the emission standards of various countries, product quality has also been approved by motorists around the world for many years, you can rest assured to buy. Thank you.
