High-speed rail construction has brought broad prospects for the polyurethane

According to statistics, the Ministry of Railways has started and plans to build a high-speed non-ballasted track has ERL line , wide bead wire , into irrigation lines, Shijiazhuang-Taiyuan line, Wuhan-Guangzhou line, the Shanghai-Nanjing line, the Harbin-Dalian line , blue lines, and the new cumulative about 4000km, which estimates the amount of the polyurethane resin required 28,000 tons . Polyurea technology , expansion joints and polyurethane elastomer polyurethane pads , polyurethane adhesives and other works have been widely used in China high-speed rail construction.Washi tape

To spray polyurea elastomer technology polyurea -based protective material development , is a new comprehensive improve the durability of concrete protective material , after which construction can form dense whole continuous seamless high strength, high elasticity protection coating , but also has good abrasion resistance, impact resistance and resistance to aging , without an additional protective layer.Masking tape


Polyurethane elastomer pads between the rails and sleepers used with good elasticity and damping properties , can buffer the intense vibrations and shocks generated when the vehicle speed through the protection embankment , with excellent abrasion resistance and electrical insulation properties and resistance to natural aging and heat resistance . Each polyurethane pad about a few hundred grams , present in the domestic high-speed rail and subway has been widely applied , a huge market demand .Sellotape


And every year, the high-speed railway construction with polyurethane adhesive consumption will reach 10,000 tons more than expected in this area in 2014 market capacity of 1.2 million tons over the next 10 years in the industry, polyurethane rubber consumption will reach about 10 million tons.Wholesale masking tape
