After nine years of construction, the Hong Kong-Zhuhai-Macau bridge opened to traffic in 2018. Connecting three major areas in the Pearl River Delta, the 55-kilometer-long bridge is comprised of a series of bridges, an undersea tunnel and artificial islands. It is envisaged to cut traffic time by 60 percent, boosting business in the Greater Bay Area. The massive transportation project called for many innovations, a number of which came from BASF. The polyurea coatings solution MasterSeal® 678 protects bridge piers from corrosion, water and wear with a rapid curing, elastomeric and waterproof membrane of high tensile strength and tear resistance; MasterEmaco® T 2900 facilitated the construction with resilient polyurethane mortar that enables the pavement to safely absorb traffic loads; MasterTop® flooring system created a durable floor in the parking garages, with exceptional mechanical resistance.
As the wind energy industry in China grows, new designs are being created for a variety of wind conditions. These also require innovations in construction. In 2018, BASF cooperated with China Shipbuilding Industry Corp (CSIC) Wind Power Equipment Co. Ltd. in the successful installation of a 120 meter high concrete-steel hybrid tower. This tower forms the mainstay of the wind turbine in a low wind speed area in Henan Province, a milestone in the history of wind energy. With its concrete segment exceeding 80 meters, the tower demands high absorption capacity for dynamic forces and a more effective load distribution of bearings between the column and the base. BASF MasterFlow® grouting solution rose to the challenge. The material demonstrates excellent long-term durability with its ultra-high strength and fatigue resistance. BASF also brought on-site technical support to ensure a quick and safe installation.
BASF materials are also crucial to the aerospace industry. The rocket assembly factory at the Tianjin aerospace base is responsible for the transportation, assembly and testing of all types of material used in rockets for space shuttles. These special tasks demand a safe and efficient work environment that can comfortably handle constant mechanical shocks, heavy impact loads and chemical exposure, as well as frequent vehicle and foot traffic. BASF’s Ucrete® MF polyurethane resin flooring system meets these needs. It provides a high durability floor surface with excellent resistance to slip, erosion, wear and thermal shock.
BASF backed the construction of Senegal Athletic Wresting Field project, the largest China-aided project in Senegal, Africa, with the supply and application of MasterTop® 1324, a resilient polyurethane flooring system. With the accurate understanding of the venue’s engineering conditions and flooring performance needs, BASF helped the main contractor, Hunan Construction Engineering to facilitate the on-schedule completion of project within two years, despite environmental and technical challenges.
In 2018, China released its first five-year plan on rural revitalization, which aims to improve living conditions and social development in rural areas.
In line with this new national strategy, BASF and Tongji University worked together to reconstruct buildings in China’s vast rural areas. The cooperation combines the university’s research capabilities and BASF’s advanced materials and technologies.
In the pilot project, the two parties have been working together to revamp an old granary in Huangyan, a 900-year-old model village in the southeastern part of Zhejiang Province. The granary is being reconstructed into a modern guesthouse, using BASF’s sustainable construction solutions such as the Finestone® wall system. The houses will be renovated with a range of environmentally friendly features, including a sunroof and a rainwater-collecting-and-reuse-system, as well as energy-saving walls and windows.
Chinese properties developers and architects are looking for more durable building materials. In 2018, China Building Materials Academy Suzhou Waterproof Research Institute (SZWRI), a leading waterproofing materials research center in China, included BASF Chimassorb® light stabilizer in the standard package of its thermoplastic polyolefin (TPO) compounds for roofing membranes, designed to protect flat roofs from leakage from heavy rains. With the stabilization technology based on Chimassorb, BASF is able to ensure the roofing polymer’s ultraviolet (UV) resistance and prolong the product’s lifespan by mitigating the chance of premature degradation due to the membrane’s exposure to UV radiation and heat.
