Talking about the coating technology of rail transit

With the development of cities, more and more cities are building rail transit, such as subways, urban rails, high-speed rails, etc. In the process of building rail transit, coating technology has become an indispensable link, which greatly improves rail transit The service life and warranty period of the vehicle, long-term protection of objects, prevent chemical corrosion, climate influence, chemical influence, etc. For example, in the case of acid rain, high temperature exposure, and large climate temperature differences, they all play a good protective role.

How is a protective umbrella with such a powerful scope and effect made?
The first is to choose the correct coating technology. At present, most of the rail transit coating technology uses water-based spray paint. Its advantage is that it is harmless to the human body and does not pollute the environment. The paint film is plump, crystal clear, and flexible. And it has the characteristics of water resistance, abrasion resistance, aging resistance, yellowing resistance, fast drying, and convenient use. The most important thing is that it dries faster than oil-based paint and has better physical and chemical properties of the coating film.

The second is the selection and optimization of the spraying production line. A good production line can not only greatly shorten the time and improve efficiency, but also make full use of coatings and greatly reduce material costs. Attraceitvechina coating production line has mature rail transit technology and production lines, which is not only suitable for rail transit, but also various automotive spraying fields. The production plan is formulated one-to-one, which greatly improves the spraying efficiency and production quality.
