Rail transit is the 'artery' of China's rising urban group. In order to ensure the normal operation of rail vehicles, the country's EMUs and EMUs undertake and handle more than 4,000 trains per day for warehousing and emergency failure. High-load maintenance The quantity also puts forward higher requirements on the supporting facilities of the moving train section and the motor train, such as repairing the flatness of the reservoir floor, wear resistance, corrosion resistance, water resistance, etc. The floor needs to withstand high frequency and high strength. Need to withstand the testing of various inspection equipment such as inspection vehicles, as well as the corrosion of cleaning agents and other tests.
Recently, the Jinan Railway Bureau Qingdao EMU repair warehouse has effectively solved the problems of poor anti-scratch capability of epoxy floor by adopting new water-based polyurethane floor technology, ensuring the integrity and aesthetics of the engine garage floor and extending it. The maintenance period of the floor. The water-based polyurethane floor paint has the advantages of excellent wear resistance, strong scratch resistance and good anti-slip performance, which further improves the safety level of the working environment of the maintenance warehouse. The product has fast curing speed and high construction efficiency. , reduce the construction time, ensure the normal use of the maintenance library. No solvent, low odor, low VOC emissions throughout the construction process, to achieve a more environmentally friendly coating.
The environmentally-friendly polyurethane floor solution is provided by Qingdao Ocean New Material Technology Co., Ltd. (abbreviation: Haimet), with excellent performance, high construction efficiency, excellent appearance and long life cycle. This technological innovation not only supports the 'one area All the way 'related project construction, solved the technical problem of stress cracking of the Epoxy floor of the EMU, and also led the application innovation of the whole project. The Qingdao EMU of the Jinan Railway Bureau gave it a high evaluation in the user report.
This Haimet environmentally-friendly floor product adopts Covestro water-based polyurethane technology, which enables end users including railway enterprises to carry out large-scale construction and renovation more conveniently, achieving waterproof, anti-corrosion and wear-resistant 'two defenses Resistant to 'engineering.
All-round technical advantage
Waterborne polyurethane flooring technology combines excellent environmental performance, outstanding mechanical properties and beautiful decorative effects. Waterborne polyurethane technology has low VOC, low odor and high environmental protection during construction. The film curing speed is fast and can be maximized. Reduce construction time and curing time, simplify construction procedures, and improve construction efficiency. It is also highly resistant to mechanical stress, dynamic stress, chemicals and water, and can be used not only for wear resistance, heavy pressure, and impact resistance. Anti-static, anti-corrosion industrial floor area, can also be used in exhibition halls, shopping malls, hospitals, homes and other fields.
Liu Peili, General Manager of Haimet, said: 'There are many problems in the epoxy resin system, such as cracking, discoloration, abrasion, and drumming. The waterborne polyurethane technology provided by Covestro has comprehensive performance and helps us to gain customer recognition. We hope to cooperate with Coase. Create a common cooperation, adhere to innovation and sustainable development strategies, overcome technical problems, and provide customers with comprehensive economic and environmental solutions.
Haimet specializes in new materials and provides product and technical support for marine engineering, naval ship equipment, port terminals, pipeline storage tanks, railway bridges, water conservancy and hydropower engineering.
