About the application and classification of printed color coated sheet

The printed prepainted plate is light in weight, beautiful, good in corrosion resistance, and can be processed directly. It provides new raw materials for construction, shipbuilding, vehicle manufacturing, furniture, electrical and other industries, and has good effects such as steel substitute wood, construction, energy saving, and pollution prevention.

In addition to zinc protection, the organic coating on the zinc layer also acts as a covering and isolating effect, which prevents the steel plate from rusting and has a longer service life than the galvanized steel sheet. It is reported that the service life of printed prepainted sheets is 50% longer than that of galvanized steel sheets.

In different regions and different parts of use, the service life of prepainted plates with the same amount of galvanizing, the same coating and the same coating thickness will be very different. For example, in industrial areas or coastal areas, corrosion is accelerated and service life is affected due to the action of sulfur dioxide gas or salt in the air. In the rainy season, the coating is soaked by rainwater for a long time, or in places where the temperature difference between day and night is too large and easy to condense, it will quickly corrode and reduce the service life.

Buildings or factories made of printed prepainted panels often have a long service life when washed by rain, otherwise they will be affected by sulfur dioxide gas, salt and dust. Therefore, in the design, if the roof inclination is greater, the more difficult it is for dirt such as dust to accumulate and the longer the service life; Areas or areas that are not often washed by rain should be regularly washed with water.

Prepainted panels can be seen in construction, shipbuilding, furniture, electrical and other industries, while the development of prepainted boards is also constantly innovating.

Modern society is an era of rapid economic and social development, and environmental protection has become a problem worthy of attention in the world. Of course, low-carbon life has gradually entered people's lives and production in China. As a representative of green and low-carbon buildings, prepainted board has gradually been accepted and used by people. The development of color coated plates has always kept pace with the times.

Printed prepainted panels have become the mainstay of green buildings. Its advantages of green, environmental protection and low carbon are important reasons for its rapid development. Low-carbon buildings refer to reducing the use of fossil sources, improving energy efficiency and reducing CO2 emissions throughout the life cycle of building materials and equipment manufacturing, building and building use. In urban development and construction, the energy saving and low carbon of buildings are destined to become inevitable topics. As a building, whether it is time or space, the prepainted board building is a low-carbon building.

In addition, the printing color coated board construction is simple, stable and low consumption, so that construction waste is reduced and harmless. The renewal and renovation of buildings interacts with the strategic goals of national resource integration and low consumption. Colorful waved interactions. The technology-based construction of prepainted panel building is a long-term national strategic reserve industry and is of great significance.
