Stainless steel also rusts, many people do not understand, but this is a common phenomenon.
We believe that there are two main reasons: 70% of them are the reasons for processing. Due to the pollution of iron and copper tools during processing, the argon gas in the welding is not well protected and oxidation occurs. In addition, excessive damage to the surface of the stainless steel factory anti-oxidation layer during processing may cause contamination of stainless steel and lead to rust; in part, the equipment type does not take into account the process needs, such as sulfuric acid in the wine industry, sulfur dioxide sealing Among them, sulfur is more corrosive to stainless steel, and 316L anti-corrosion stainless steel plate is used in the industry for the top or upper tube section.
In view of this situation, there are three solutions: First, the surface of the stainless steel plate is protected from being affected during processing. Several blending tanks can be concentrated and treated at the bottom. For the processing party, the welding material is higher than the base metal; the second is the full protection of argon; the third is the film protection, using stainless steel tools, wooden hammers, rubber, carpet, wood and other tools to contact the surface of the stainless steel plate to avoid iron , copper tool contact.
The 200mm Traffic Signal Light has low power consumption, and the current passing through is small but it can emit a very large light. It not only saves power resources, but also makes it easy for drivers, pedestrians and drivers to see the instructions of the traffic lights, and the traffic lights The life span is very long. A normal traffic signal lamp can generally be used for more than 100,000 hours. It is very durable and can greatly reduce costs and manpower. The use of the inclined surface design of the transparent lens makes the surface of the traffic signal difficult to accumulate dust. , It will not affect the brightness due to dust accumulation for a long time. The shell also has good waterproof and dustproof functions, and has good flame retardancy, which can greatly improve the service life and use quality of traffic lights, and ensure This improves the normal and long-term use and safety of the transportation system.
There are many types of 200mm traffic signal lights, 200mm full plate with two red and green lights, 200mm full plate with red, yellow and green three lights, 200mm red fork and green arrow single light, 200mmm red fork and green arrow two lights, 200mm arrow lights, etc.
