Project Outline

The Beijing-Shanghai High-Speed Railway is a 1,318 kilometers (819 mi) long high-speed railway that will connect two major economic zones in China: The Bohai Sea Rim and the Yangtze River Delta. Aromatic Polyurea was selected as the waterproofing layer on the bridge concrete beams.

?      Whole Length：1318Km

?      Slab Ballastless Track,32.6×8.8m per Beams

?      Design Speed：350Km/h

?      Strength Grade: C50

?      Aromatic Polyurea Estimated Amount:22000 Tons

?      From Dry North to Humid South of China

?      Aliphatic Topcoat applied between 2 tracks

?      Polyurea Installation Period: 1 Year

Drafting Guideline

According to the experience of being engaged in R&D on polyurea for 15 years, Prof. Huang took part in drafting “Temporary Technological Guideline for Spraying Polyurea As the Waterproofing Layer on the Bridge Beams of Beijing-Shanghai High Speed Railway” (B-S Project).

Jobsite Training

In need of the necessary of professional applicators for B-S Project, the First Training Course on Polyurea Technology at the Jobsite of Beijing-Shanghai High Speed Railway successfully hosted by Research Institute of Functional Materials, Qingdao Technological University.

All attendees received hands-on, in-depth training on how to use and troubleshoot plural component equipment, spray guns, machine hoses, parts and accessories; Each participant also spends time learning the core content of the monograph “Spray Polyurea Elastomer Technology”, Shot blasting machine, automatic spray rig, adhesion tester, thickness gauge, temperature measurement instrument, Qtech-112 all-weather substrate processing system, fast identification method of pure polyurea vs hybrid and proper spray techniques for applying Polyurea.

Technical Service

“Qingdao Shamu International Trade CO., LTD.” is in charge of the Beijing-Shanghai High Speed Railway polyurea waterproof layer formulation, engineering design and construction, raw material and spray equipment consulting.

We also consult in design, formulation, training, testing, application and supervision in Beijing-Shanghai High Speed Railway polyurea project.

Our working Conference was successfully held on Dec. 18~19, 2009 in Qingdao and solved the coating delamination problem which widely existed in B-S Project especially in cold winter. Qtech-112 all day weather surface preparation system show excellent low temperature compatibility to many polyurea products, it answered the adhesion problems which confused entire polyurea industry on winter construction.
