Brief Introduction of Polishing Performance of Stainless Steel Quick Coupling
I believe everyone is familiar with stainless steel quick couplings, and I will introduce you to several ways to wash them. Because it has been left in the air for a long time, it will inevitably be contaminated with dust or dirt. At this time, we can wash with soap or warm water. If it is the surface of the trademark, we will use a weak lotion and warm water to rinse.
If it is contaminated by grease, etc., we should wipe it with a soft cloth and then clean it with a special detergent. Sometimes, we will see rainbow patterns on its surface, which are caused by excessive use of detergent or oil. We can use mild detergent in warm water.
As long as we choose the correct cleaning method and maintenance method, we can extend its lifespan. No matter what stainless steel product is, it needs everyone's maintenance and maintenance, so that it can be used for a longer time.
The copper sulfate point test is a convenient way for us to quickly distinguish between ordinary carbon steel and stainless steel. The concentration of the copper sulfate solution used is 6-10%.
Before the spot test, the test area should be thoroughly cleaned of grease or various impurities, and a small area should be polished with a soft abrasive cloth, and then the copper sulfate solution should be dripped into the cleaned area with a dropper. Ordinary carbon steel or iron will form a layer of surface metal copper within a few seconds, while the surface of stainless steel does not produce copper precipitation or display the color of copper.
