Surface treatment process of japanese sinkers dissolution

Dec. 05, 2018

Today, Snow continues to tell you about the Japanese sinkers (dissolution sinker).

 

In my last article, I mentioned how to find a real dissolution sinker supplier in China. Then I received some messages and emails, I am very happy that my article can help you.

This will be my biggest motivation, no matter how busy I am in the future, I will insist on updating at least two blog posts every week.

I usually come to find topics that are of interest to you and then write articles through my experience and the help of technicians around me. I have a suggestion, I hope everyone can email me and tell me the topics you are interested in (about the metal filter element).

 

We continue the topic of the previous blog. When we find the real supplier, the next step is to confirm the quality.

 

The last step of the dissolution sinker - cleaning

 

Why need to clean?

 

There are two reasons:

 

1. Bright looks more upscale

2. Increase corrosion resistance and maximize service life

 

For the user, the first role is not practical. Whether the appearance is bright or not has no effect on the use, mainly used by sellers to increase product prices and grades.

The second role is crucial for us.

 

Can the corrosion resistance of dissolution sinker be increased as long as they are cleaned?

 

No...

This involves a patented technology of our company - physical cleaning.

I can't disclose the details of this technology too much.

After a large number of experimental comparisons, the corrosion resistance of our products through this cleaning process is increased by 40%.

 

Next, I'll talk about electropolishing for dissolution sinker.

 

Reducing the surface roughness of the filter element by the electrolysis process, in fact, it's about removing the oxide film from the surface of the filter element.

The process that increases the finish and gives the metal surface a mirror-like finish and texture.

Especially for the 300 series stainless steel, the effect is very good.

ZHEHAN has professional electropolishing equipment, we can finely control the thickness of the polishing layer.

(The polished filter element can be used in nitric acid solution)

 

This process is suitable for complex workpieces. It is the most commonly used process for metal products.

 

 

The content of the surface treatment of the dissolution sinker is written here. In fact, this is also the surface treatment process of most metal products. If you have any other questions, please leave a message.
