Polyurethane adhesive is used in new railway products

China has a vast territory, deep and wide inland, and a large population. Therefore, as an important national infrastructure and popular means of transportation, railway plays an important role in China's comprehensive transportation system. However, in the rapid development of China's economy, there is a long-term shortage of transport capacity, and the railway development speed is far from keeping up with the pace of demand, forming a serious "bottleneck" problem

from 1978 to 2008, China's annual GDP growth rate was as high as 9.40%. The national operating mileage has only increased from 51700 kilometers to 80000 kilometers, with an average annual compound growth of only 1.4%, far lower than the growth of GDP. Especially from 2002 to 2008, China's economic structure has undergone major changes, and the economic aggregate has accelerated. The average annual growth rate of China's GDP is far more than 10%, while the average annual compound growth rate of railway here is only 1.64%

railway has become an industry that needs to be vigorously developed at this stage and for a long time in the future. Policies and measures to break through the "bottleneck" of railway transportation capacity are giving birth to the railway industry chain with great potential

East China CNC is the only machine tool enterprise in China that has fully independent intellectual property rights of CNC system, and the only domestic enterprise that can produce Borg plate grinder in 2015. In 2010, the company will still benefit from the construction of high-speed rail

benefiting from the breakthrough development of high-speed rail, the performance of new materials will maintain a high growth in the next few years. A number of new railway products are expected to be launched in 2010. Shock absorption and noise reduction components of high-speed railway multiple units, ultra-high molecular weight polyethylene wear-resistant plates, polyurethane adhesives, etc

among them, there is a strong demand for railway line elastic components. As the only supplier of high-speed railway turnout elastic base plate in China, Shidai new material will benefit from strong demand. 2011 and 2012 will be the peak of China's high-speed railway completion. Therefore, the demand of high-speed railway turnout elastic base plate industry will grow rapidly in the next three years. At the same time, due to the large-scale development of domestic urban rail transit, the shock absorber of Shidai Xincai urban rail transit will gradually open up the market

in addition, the business of elastic components for railway vehicles of Shidai Xincai will grow steadily. The Ministry of Railways implements the production license system for the elastic components of the railway system, and the entry threshold of this industry is high. Therefore, the market competition pattern in the field of automotive elastic components is relatively stable. Especially in terms of the elastic components of electric locomotives, Jiuli special materials of the new nuclear power restart of the times; Small metal materials basically monopolize the market
