The Hong Kong-Zhuhai-Macao Bridge Was Officially Opened Today, And Plastics Played A Major Role In The Construction Process.

The opening ceremony of the Hong Kong-Zhuhai-Macao Bridge in the east, connecting Zhuhai and Macao in the west, was held in Zhuhai, Guangdong this morning. The official opening of the bridge means that Hong Kong, Zhuhai and Macao will form a “one-hour living circle”, and the vast ocean will be transformed from Tianzhu. With a total length of about 55 kilometers, the bridge is the longest span of the world and the longest sea-crossing bridge in the submarine immersed tunnel!

As the longest spanning sea-crossing bridge with the longest span of the sea and the submarine immersed tunnel, the Hong Kong-Zhuhai-Macao Bridge was constructed using the deep buried immersed tunnel design and construction technology, which is called the miracle of architectural history. All kinds of high-tech building materials, including a new polymer plastic template developed by a domestic company, played a considerable role in the construction of the artificial island roundabout. It is reported that the plastic template is made of thermoplastic long fiber reinforced polymer composite material. The weight of a square meter mold is about 10kg, which is only one-seventh of the steel mold. It also has the characteristics of wear resistance, corrosion resistance and high strength. The plastic template adopts a unified composite component, which can be flexibly and quickly templated and assembled. The construction personnel can quickly grasp the operation with simple training. At the same time, there are no problems such as residual nails and spikes in the template during construction, which can greatly reduce construction safety hazards.

In fact, not only the super projects such as the Hong Kong-Zhuhai-Macao Bridge will use new plastics instead of traditional building materials in construction. In fact, the concept of “reforming wood to plastic and replacing steel” has been widely used in other projects and other industries. . With the rapid growth of domestic demand for high-tech engineering plastics in recent years, its position in modern manufacturing is becoming increasingly important. For example, various types of new energy vehicles, drones and even some spacecraft will use engineering plastics extensively. The finished parts are used to achieve weight reduction and light weight; some building constructions use various new engineering plastics in construction to replace structural materials that are difficult to install and are susceptible to corrosion.


In recent years, the development of China’s engineering plastics industry is particularly rapid, not only higher than the development speed of the ordinary plastics and petrochemical industries, but also has a certain international reputation. Major engineering plastics companies are also actively introducing new products to meet the needs of the market. The concept of “reforming wood and replacing steel” not only conforms to environmental protection and green, but also has become a new trend in international manufacturing, which is also a promotion for the engineering plastics industry.
