"In terms of product performance, engineering application performance and continuous production technology and equipment, it has reached the international advanced level as a whole.
Based on the self-developed material system and slow foaming temperature control technology, the one-step molding technology of 'near-zero defects' large-thickness synthetic sleepers is an international leader.
".
.
.
" On December 9, the reporter learned from Luoyang Kebos New Material Technology Co.
, Ltd.
that for the research project of large-thickness one-shot synthetic sleepers for rail transit, the achievement evaluation team headed by the famous materials expert and academician of the Chinese Academy of Engineering Zhang Union The above evaluation is given
.
Luoyang Corpus is a holding subsidiary of Longhua Technology Group (Luoyang) Co.
, Ltd.
, the first GEM listed company in Luoyang
.
Traditional railway sleepers usually use concrete sleepers and wooden sleepers
.
According to Wei Jianguo, chief engineer of Kebos, the resin sleeper is made of glass fiber reinforced foamed polyurethane, and its density is only 1/3 of that of concrete sleepers, which is only comparable to that of wood, but its waterproof and compressive effect is better than that of wooden sleepers.
The ton-heavy rail vehicle is also stress-free
.
Resin sleepers, which are emerging technology products of rail transit, also have shortcomings
.
"In the experiment, the concrete sleeper can meet the fatigue impact resistance requirement of 2 million times, but the traditional resin sleeper can only withstand 100,000 times
.
In response to this technical bottleneck, the company focused on tackling key issues such as resin formulation, resin and fiber low-frequency shear vibration impregnation, and broke through key technologies such as slow foaming control, curing temperature gradient and resin fiber impregnation uniformity to achieve 30-300 mm synthesis.
The sleeper is formed in one step, and it is the first in the world to master the large-thickness one-step forming processing technology, which extends the life expectancy of resin sleepers to more than 50 years, and is even more durable than concrete sleepers under complex and special working conditions
.
According to Wang Yong, executive deputy general manager of the company, the product has been applied to the Chaotianmen Yangtze River Bridge in Chongqing, as well as rail transit projects in Beijing, Guangzhou, Shenzhen, Foshan, Changzhou and other cities
