Shorten the running time thanks to ... polymer

The journey to run a train from Hanoi to Ho Chi Minh City in the past took 34 hours, but now it is shortened to 29 hours and still ensures a high level of safety, every year saving the State many billion dong. In order to achieve this miraculous change, the railway industry has applied products from polymers to produce plastic bases and rails by the Institute of Tropical Technology (Vietnam Institute of Science and Technology).

A few years ago, the production of plastic bases, ray toads - an accessory in the structure of railway tracks that reduced noise, shortened the train running time seemed to be unthinkable for manufacturers in country. But recently, the Institute of Tropical Technology has successfully implemented the State-level Test Production Project on "Improving the technology of manufacturing polymer blues ( polyamides / polypropylene ) to produce plastic bases and rails for sugar industry. iron "and obtained unexpected results.

Embarking on implementation, scientists have met many difficulties because of the high risk in the implementation process, besides the price of raw materials for making plastic bases, toads and rails is increasing, the time for implementation is project urgently .

Refusing to cope with these obstacles, on the basis of the technology of manufacturing compatible substances, the technology of manufacturing polymer materials and production lines synchronously equipping, from 2003 to 2004, Scientists at the Institute of Tropical Technology successfully researched and went into production, providing 1,138,790 plastic houses, 3,000 ray toads and 7,000 kg of polymer blen, saving the State a lot of foreign currencies.

Successful production, in the process of testing and application has also shown that polymer blene has mechanical properties and is resistant to good tropical climate. Different from imported products, scientists confirmed that ray toad can be used over 5 years without maintenance and replacement. This product has helped reduce noise when the boat rolled, while shortening the train running time while ensuring high safety.

Talking about the socio-economic efficiency, the project leader - Dr. Dao The Minh - said that Vietnam now actively meets the regular needs of plastic products of companies and businesses. in the railway industry, contributing to creating jobs, proactively manufacturing for domestic establishments, reducing product costs. Plastic base products also meet unexpected and urgent needs to quickly overcome the consequences of broken road sections. On that basis - the railway industry has allowed the application of polymer blen and test application of vossloh plastic core products of prestressed concrete sleepers.

Dr. Dao The Minh added: Up to now, although it has supplied its own products to domestic units, the "ambition" of the scientists of the Institute of Tropical Technology is not only in scope. "village pond" that must seek to reach the big sea. In order to do this, it is necessary to have a campaign to promote and market products, and departments need to coordinate closely to find a common voice for the "domestic child" to serve such railway industry. gender.
