Generally, the quality of the electroplating process is regarded as a key evaluation index due to its anti-corrosion work ability and appearance. The corrosion resistance is also an office environment that emulates the commodity, and is set as a test standard. People often use corrosion-resistant machines to test their corrosion resistance, and Its many aspects of the etch test.
Self-piercing rivet manufacturers must do metal surface treatment after producing and processing self-piercing rivets. Metal surface treatment can not only change the appearance of self-piercing rivet standard parts, but also improve the anti-rust treatment and corrosion resistance of self-piercing rivets. Generally, the quality of metal surface treatment is regarded as a key evaluation index due to its anti-corrosion work ability and appearance. Corrosion resistance is also an office environment that emulates a commodity, and is set as a test standard. People often use corrosion-resistant machines to test their corrosion resistance, and Multi-faceted etch test.
Salt spray test, firmly believe that the self-piercing rivet standard parts manufacturing industry is no stranger. This test is indispensable for the production of self-piercing rivets, busbar rivets, self-piercing rivets and other standard parts. It is this kind of reasonable resistance to corrosion and erosion of the rivet process performance.
What about salt spray testing? It is the key to the salt spray test machine equipment standard to evaluate the corrosion resistance of metal composite self-piercing rivets, self-piercing rivets, self-piercing rivets and other standard parts.
The salt spray test machine is a kind of machine that artificially uses some test chambers to simulate and simulate the corrosion-resistant natural environment. The time of detection is always within a short period of time. Metal composite self-piercing rivets, self-piercing rivets, self-piercing rivets and other standard parts are thoroughly exposed to the natural environment, which is attributed to the natural salt spray test. However, its detection time is longer, and many standard parts inspections in the processing industry are not available. Generally, the salt spray test machine equipment is selected, and the salt spray test machine equipment is used to detect the natural environment chloride salt concentration relative to the multiple of the natural corrosion-resistant water content, and the time is relatively reduced.
Corrosion-resistant etch causes damage or mildew problems in metal composites or their properties in the natural environment. Most of the erosion occurs in air pollution, with corrosive components and etching elements such as co2, ambient humidity, temperature transitions, and air pollutants in the air. Corrosion-resistant etch is the most common and most devastating air etch. Corrosion resistance refers to the air of chloride. Its key etch component is the chloride salt in the deep sea, sodium oxide. The key is from deep sea and domestic saline-alkali areas. Corrosion-resistant metal substrate self-piercing rivets, self-piercing rivets, self-piercing rivets and other surface parts of the standard parts are etched because of the chloride ion passing through the stainless steel passivated air oxide layer and safety protective layer and internal metal The material is caused by electrochemical corrosion. Together, chloride ions have the necessary hydration energy, which is very easy to be sucked on the surface of the metal composite self-piercing rivets, self-piercing rivets, self-piercing rivets and other standard parts of the porosity, gap run and replace the isopropyl titanate The oxygen in the ester layer turns the insoluble compound into a soluble chloride, turning the passivated surface layer into a cheerful surface layer. Leads to very bad side effects on product quality.
Self-punching rivets, self-piercing rivets, self-piercing rivet metal composite materials after the electroplating process, after plating metal surface treatment, and then the salt spray test is not in compliance with the quality standards of corrosion-resistant and anti-corrosion products, determine After the accuracy, the original product will be released to the broad customer application.
Self-piercing rivets, self-piercing rivets, busbar rivet standard parts must pay special attention to the many problems in the plating process, it is very easy to cause self-piercing rivets, self-piercing rivets, busbar rivet standard parts are not qualified The key reason.
