Jilin Chemical Fiber Group Pformation And Upgrading Of "New Silk"

In order to improve the differential rate of traditional products and enhance the added value of products, Jilin chemical fiber Refco Group Ltd has intensified its innovation, and has developed a new type of functional fiber products, such as high-tech fiber and flame retardant fiber, by combining production, teaching and research.

From 1 to October this year, the company achieved sales revenue of 4 billion 720 million yuan, an increase of 11.9% over the same period last year.

Carbon fiber is a kind of advanced material with many excellent properties, such as low specific gravity, high strength and high elasticity. However, because of the strict technical blockade abroad, China has never been able to achieve large-scale production.

Jilin chemical fiber based on the development of strategic emerging industries, through cooperation with Changchun University of Technology, independently developed the "wet two step method" of carbon fiber precursor production technology, created the domestic precursor production technology of the first step, reversing the situation of China's carbon fiber products supply, and with the annual capacity of 5000 tons of carbon fiber precursor, become the largest in China.

Production base.

At present, the grade of carbon fiber has reached T400 level.

Annual output of 5000 tons of bamboo

At the scene of the continuous spinning pformation project, the reporter saw that the factory building of bamboo filament production is under construction, and the project will be put into production in July 20th next year.

The sale income can reach 179 million yuan after delivery.

At the 20 thousand ton acetic anhydride conversion site, workers are removing rust for machines.

At present, the project construction is coming to an end.

It can achieve sales income of more than 100 million yuan after delivery.

In production, Jilin Chemical Fiber Co., Ltd., in cooperation with Italy Montel, has independently developed the pan acrylonitrile carbon fiber precursor production process package and equipment technology, realizing the deep integration of industrialization and informatization.

In the production of rayon filament, Jilin Chemical Fiber Co., Ltd., in cooperation with the German card company, introduced continuous spinning technology to speed up the pformation of traditional technology, changing the original labor intensive production mode and improving the labor productivity.

At present, the global defense aerospace safety company, British BAE systems, has recently developed a liquid super gel material bulletproof vest, which means that this bulletproof vest will provide lighter and more flexible body defense measures to soldiers in the future.

This liquid gel can be placed between the Kevlar layer. Its resistance to bullets is about five times that of steel, but it is half the weight of ordinary bulletproof clothing and thinner than that of it.

Liquid bulletproof clothing uses Shear Thickening Liquid, which contains special particles that can be suspended freely. When the liquid is attacked by a bullet, these special particles will collide and form resistance to this disturbance.

When the disturbance force is large enough, the particles will actually "lock" together.

Therefore, when the bullet hits the bulletproof vest at a certain speed, the liquid armor will absorb the collision energy and become very strong in a short time.

Stewart penny, head of BAE systems design and materials business development division, explains that it can be imagined that when external forces slowly hit the shear thickening liquid device, it will feel a very small resistance, while a faster external force will feel the resistance increase.

This special liquid material can also be combined with the traditional Kevlar's bulletproof vest. When combined with liquid materials, Kevlar's bulletproof vest has strong flexibility, which is 45% thinner than that of the existing bulletproof vest.

At the same time, liquid gel can also restrict the loosening of the yarn of Kevlar's bulletproof vest and disperse the collision energy.
