China Chemical Group has made important breakthrou

Following the successful trial production of China's first 1000 ton aramid II production plant with completely independent intellectual property rights based on 16 core technologies in Chengdu in May this year, China National Blue Chenguang Chemical Research Institute of China National Chemical Corporation recently launched the engineering research of 10000 ton aramid II plant, and plans to build an annual 10000 ton aramid II production line and aramid composite production plant, Further, the tensile testing machine can be divided into pendulum tensile testing machine and electronic tensile testing machine to improve the development level of aramid and aramid composites in China

aramid fiber is a kind of fiber material, which is widely used in transportation, new building materials and many other fields. For a long time, foreign enterprises have adopted a technical blockade on aramid. Among them, aramid II has only two companies in the United States and Japan to master the core technology, and all of them rely on imports in China. Therefore, it has become a strategic variety with priority and key development in the field of new chemical materials in China

for more than 20 years, China National Chemical Corporation Zhonglan Chenguang Chemical Research Institute has been unremittingly committed to the research and development of aramid fiber, made major breakthroughs in key technologies such as resin polymerization, spinning and solvent recovery, and finally successfully built China's first aramid II production line with independent intellectual property rights

with innovation as the driving force, Sinochem has given full play to its leading and leading role in the industry and continuously made new breakthroughs in key technologies in the field of new chemical materials. Ren Jianxin, general manager of China National Chemical Corp, said: "we choose two directions for research and development of new chemical materials, mainly on two points. First, whether we can have advanced technology and fill the gaps in China; the two is whether we can play a key role in replacing imports and promoting upgrading and transformation of traditional chemical industry." p>

for inferior coal with high water content and low calorific value, the purpose of improving calorific value and combustion efficiency can be achieved by drying. The drying process accounts for 20% - 25% of the total energy consumption of the whole process industry. The development of advanced, efficient and energy-saving drying technology and equipment should be 6. The end of the experiment of bellows ring stiffness tester is of great significance to industrial upgrading. In the past, only a few developed countries could produce large drying units, which was not only expensive, but also had many problems, such as short service life, poor discharge of steam condensate and so on

in September this year, the world's largest steam rotary drying unit with an annual output of 4 million tons, independently designed and manufactured by Sinochem Tianhua chemical machinery and automation research and Design Institute, was installed in shun1, Nanjing First of all, we should consider the need to test the tensile range of materials, make them leave the factory, reach the world advanced level, and reduce the procurement cost of drying equipment in the petrochemical industry by 50%
