When it comes to railway stations, the first thing that comes to mind is the well-regulated, monotonous building. Few people associate it with the sense of design and brilliance. However, in Jiangcheng Wuhan, the railway station there is not new, the unique "Nine-Headed Bird" and the wave shape are integrated, and with its gorgeous and elegant appearance, it has won the title of "the most beautiful building in the world".
Of course, beauty is not just the whole of this railway station. In addition to its rich architectural style, Wuhan Station also provides a comfortable and safe travel experience for tourists from the south to the north with excellent safety. All of this stems from polycarbonate materials that are more plastic, more load-bearing and more environmentally friendly.
With the continuous development of the construction industry, the demand for building materials has exceeded the scope of reinforced concrete. In recent years, the emergence of new building structures has placed higher demands on building materials. In addition to the most basic fire resistance, impact strength and durability, building materials are also moving in new directions.
First of all, on the basis of ensuring the safety of buildings, people prefer materials with higher plasticity and lighter weight, thus ensuring the designer's styling needs, and reasonably reducing the structural weight and increasing the use space of buildings. Secondly, the innovation of building structure also puts forward new requirements for new materials in many aspects such as heat preservation, weather resistance and light transmission.
High-tech craft materials and German craftsmanship
Coase is the world's leading manufacturer of high-tech polymers. Its polycarbonate sheet not only meets the basic requirements of high fireproof standards and impact strength, but also leads the industry in terms of light weight and plasticity.
Robust guards with high fire resistance and high impact resistance: In the construction field, safety, strength and durability are the most important requirements in any case, and Covestro polycarbonate sheet fully meets these three needs.
According to the requirements of fire protection standards for public building materials, polycarbonate sheets are far below the limit of smoke toxicity, and can be self-extinguishing after leaving the fire, and the molten droplets will not burn. At the same time, compared to other materials, the Makrolon® polycarbonate sheet is nearly 200 times more impact-resistant than the glass after being impacted by the same strength, 20-30 times that of PMMA. In addition, thanks to the blessing of the UV layer coextrusion technology, the sheet material can maintain various physical properties during the warranty period, not only the impact strength does not change much after 5 to 10 years of use, but also the durability of the material. Greatly improve.
Safety in times of crisis: When the building materials with glass texture encounter impact, a large amount of debris will be generated, and the human body will be different. The polycarbonate sheet will only deform or break under the impact of external force due to its own advantages. Fragments are generated, which further reduces the harm that may be caused to people when disasters such as earthquakes occur.
Lightweight and flexible: In addition to the three advantages of safety, strength and durability, lightweight and high plasticity can be said to be the outstanding advantages of polycarbonate sheet, and it is also benefiting from this, many original architectural design concepts have become a reality. At present, polycarbonate sheets have been successfully used in many public buildings, commercial buildings and industrial buildings at home and abroad. The roof of the California Academy of Sciences has been replaced by a lighter weight and easier to shape the Makrolon® sheet, which has reduced structural support and achieved a more aesthetically pleasing design while reducing costs, bringing life to people's lives. A touch of art.
Fearless heat and ice: Weather resistance is also a major feature of polycarbonate sheets. The long-term durability of polycarbonate sheets is much higher than that of other materials such as polypropylene and PVC, and their load capacity and stability can be maintained even when exposed to extremely high or low temperatures for a long time.
The superior advantages of polycarbonate sheeting have been highlighted in the corridor of Yiwu Small Commodity City in Haicheng, Liaoning. As a building standing in the cold regions of northern China, the corridor part not only needs to withstand the continuous low temperature weather in the northeastern winter, but also can withstand the impact and backlog of wind, snow and hail. Coxon's Makrolon® 12mm transparent solid sheet meets the weathering requirements of the corridor with its high wind and snow load capacity. At the same time, its weight per unit area is only 32% of the hollow laminated glass, which further improves the installation efficiency, saves the steel skeleton structure, and ensures the effect requirements of the entire project.
Ubiquitous polycarbonate sheet
Costron polycarbonate sheet has been widely used in many fields except construction, such as transportation, industrial, LED lighting, etc. due to its excellent fire resistance, impact resistance and high plasticity. The application of this innovative material offers engineering companies, designers and owners a new material choice. Covestro is supporting the development of the Asia-Pacific local economy with global technology and knowledge, and has become one of the major players in the Asia-Pacific local economic construction.
For example, the three tunnel entrances of Zhangcheng Expressway are often faced with strong winds, rain and snow due to the climatic conditions in the mountainous areas, resulting in a large amount of snow on both sides of the tunnel, and frequent traffic accidents. To this end, the local authorities plan to put a snow-proof awning on the entrance and exit of the tunnel, and put high demands on the snow load capacity and durability of the awning. After repeated comparisons, Coxon's 6mm blue solid polycarbonate sheet was selected as a awning material for its high impact resistance and durability, not only meeting the needs of the construction side, but also beautifully The contour shape also adds a beautiful landscape to Zhang Cheng Express.
In addition to the high fire resistance, impact resistance and high plasticity properties often mentioned in the construction field, polycarbonate sheets also have excellent light transmission properties, which can meet the lighting requirements of different environments. Moreover, its light transmittance has an extremely high stability, and it can ensure that its light transmittance does not fall by more than 6% during the 10-year quality guarantee period. The advantage of this high light transmission has been exploited and utilized on the Shanghai thermal power transmission belt.
Coal is one of the important fuels in the thermal power generation process. Before the pulverized coal is burned, it needs to be transported from the coal yard to the coal mill to form pulverized coal by a conveyor belt. In the past, the steel belt was often used as a protective sheet. However, since the steel protective sheet did not have translucency, once the coal block was stuck in the belt, it was often necessary to perform a step-by-step inspection of the entire conveyor belt, which was very inconvenient. With the Makrolon® transparent solid board, its light-transmissive visual characteristics help the tester to quickly investigate the cause and improve work efficiency. In addition, the high impact resistance and safety of the polycarbonate sheet further avoids the safety problem caused by the bombing of the coal block to the shield.
In addition to the industrial field, the excellent light transmission of polycarbonate sheets makes them the perfect choice for advertising light box panels. For example, the Guangzhou Metro advertising light box panel currently using polycarbonate sheet not only does not have the phenomenon of “rib ribs†which often occurs in general light box boards, and achieves excellent diffusion effect, and reduces the use of LED light sources to meet energy saving requirements. .
A versatile polycarbonate sheet that combines robust safety with stylish plasticity is just one example of Covestro's many high-tech polymer materials. Today, our materials are widely used in electrical, automotive, medical, construction, and all aspects of modern life. Covestro believes that in the near future, there will be more buildings like Wuhan Station that are as strong and durable as the ones that are shining, and Costron will continue to work with you to create a wonderful future. world.
