According to reports, 96 rails have a total length of 145 meters, and the whole vehicle has 4 sets of grinding wheels and 96 grinding wheels. It is called "96 rail grinding trains" and is the most advanced rail grinding train of the national railway. Compared with the traditional manual grinding, the 96-gauge grinding train has the advantages of fast grinding speed, no scratch on the rail surface, and reduced train running noise.
In order to meet the needs of rapid development of high-speed rail, the Nanning Railway Bureau introduced the first 96-track rail-grinding trains in early October, and in the mid-October, it was put into the grinding operation of the Guiguang Railway. The Guangxi section of the Guiyang-Guangzhou Railway plans to carry out 15 days of rail grinding. operation. It is understood that the high-speed rail grinding is carried out before the opening of the high-speed rail, mainly to fully polish the surface of the high-speed rail to improve the service life of the rail and the comfort of passengers.
Product introduction
HHCMS-240 type Carbon Molecular Sieve
HHCMS-240 is a new kind of non-polar adsorbent. It is designed to extract nitrogen-rich gas from the air. It is suitable for separating nitrogen from the air.
The most notable features of the carbon molecular sieve are high gas-producing efficiency and low waste, especially nitrogen with a purity higher than 99.9%.
It is widely used in large air separation and sheet making equipment, and the application field covers the high-end aspects such as the storage and transportation of crude oil in yibi ships.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
