Focus:The use of powder coatings on high-speed guardrail will increase by five times

With the "green and sustainable development" gradually become the mainstream of industrial development. How to integrate into the construction of transportation and achieve high-quality development of transportation has become a topic of common concern in the industry. Reasonable selection of coating process is very important to prolong the life of high-speed facilities.

The data show that the highway guardrail is made of steel pipe and steel column processing and painting, and its surface coating is exposed to the atmosphere all year round. In the outdoors to withstand the sun exposure, rain and snow erosion, seasonal temperature changes and other media erosion, resulting in economic losses are very surprising.

Therefore, it is increasingly important to reduce the waste of resources caused by corrosion, improve the sustainable development ability of expressways, improve the safety, reliability, aesthetics and prolong the service life of steel components. The coating of the guardrail should not only resist corrosion and weather, but also have sufficient mechanical strength. Although the current anti-corrosion treatment technology, such as hot dip galvanizing, hot dip aluminum plating and other processes have been very popular, but with the progress of the era, the concept of "green, environmental protection" has gradually been recognized by people, people realize that the large-scale open hot dip plating is a kind of high energy consumption and high pollution industry. This eliminated the workshop process, and turned to the development of "environmental protection and energy saving" new technology. The electrostatic spraying process can effectively reduce the high temperature and heat loss required for molten zinc ingots and aluminum ingots. At the same time, the automatic spraying line of powder coating improves the product quality and efficiency, reduces carbon emissions, and has very important economic and social benefits for the construction of resource-saving and environment-friendly transportation. Therefore, powder coating is now used, that is, "epoxy zinc rich powder + polyester powder" process.

Powder coating not only has a good effect, its simple and generous design can also be naturally integrated into the landscape with the highway, reflecting the harmonious development of the road and the environment.
