At the same time, China's ultra high molecular weight polyethylene fiber technology is also upgrading at the same time. P

In July last year, a complete set of industrialization technology of ultra high molecular weight polyethylene (UHMWPE) fiber dry gel spinning technology jointly developed by Nanhua Research Institute, Jiangsu Yizheng chemical fiber company and China Textile Science Research Institute was rejoice after winning the first prize of Sinopec science and technology progress. The first domestic dry spinning process UHMWPE fiber industrial production line constructed by Jiangsu Yizheng chemical fiber company has successfully produced 50D to 300D series of high value-added fine denier products.

This indicates that the UHMWPE fiber dry spinning technology has broken the monopoly of foreign technology.

< p > in the past, most of the "a href=" //www.sjfzxm.com/news/index_c.asp "anti cutting gloves" < /a > were all metal gloves, which were made of steel gloves and made of numerous small rings.

Its function is to protect the hands from being cut when using cutting machines.

Nowadays, ultra high molecular weight polyethylene fiber has entered into the field of anti cut gloves, making the performance of anti cutting gloves more excellent, and the quality of its products has gone up to a higher level.

The future application of UHMWPE fiber will also be more extensive. Especially in recent years, due to conflicts and wars in all parts of the world, the spread of terrorist incidents has been increasing. The military equipment industry has been developing rapidly. More and more attention has been paid to the development and research of bulletproof materials. More and more ballistic materials have been put into use. Considering the convenience and comfort of use, fiber materials have gradually replaced traditional steel and ceramics and become mainstream bulletproof materials.

Fiber also includes carbon fiber, Kvlar fiber and ultra high molecular weight polyethylene fiber.

They have been applied to bulletproof clothing, bulletproof armor and bulletproof helmets in bulletproof area. UHMWPE has attracted much attention due to its superior ballistic performance.

< p > ultra high molecular weight polyethylene (UHMWPE) fiber is one of the three high performance fibers tied to carbon fiber and aramid fiber. It is an important strategic material and high technology material at home and abroad. However, there is a lack of special resin production technology at spinning stage in China, and the spinning technology and production equipment level are still far from developed countries.

And with the efforts of domestic research institutes and technical departments, we will continue to produce high-quality ultra-high molecular weight polyethylene fiber products in China's regional market.

Under the support of the key project of "ultra high molecular weight polyethylene fiber key technology" in the "11th Five-Year" 863 plan new material field, 4 topics, such as the super high molecular weight polyethylene resin, fiber and composite materials, have also been made important progress by the Zhejiang Ningbo Dacheng new material Limited by Share Ltd and the Chemical Research Institute of the Chinese Academy of Sciences. The technology acceptance was also passed in the first half of 2013.

The project has improved the performance of catalyst and solvent, developed two grades of fiber grade ultra-high molecular weight polyethylene resin, established pilot plant, formed 20 thousand tons / year fiber grade ultra high molecular weight polyethylene resin continuous industrial production capacity, developed fiber surface modification and other new technologies, developed a large capacity non continuous gel UHMWPE fiber industrialization preparation technology, single line production capacity increased to 400 tons / year. The series of bulletproof products, such as high-performance, lightweight weft woven bulletproof vest, high speed low twist stranding UHMWPE fiber high strength rope and advanced grade coated yarn anti cutting gloves have been industrialized mass production, and achieved good economic benefits.

The project also established the enterprise standard for UHMWPE fiber grade resin testing, and proposed the national standard of fiber grade UHMWPE resin.

The implementation of this project has promoted our country's ultra high molecular weight polyethylene (fiber technology), has developed a series of high-performance downstream products, has reached the target of similar products abroad, and promoted the competitive power of China's ultra high molecular weight polyethylene resin, fiber and composite products in the international market.

< p > the United States accounts for about 70% of the total demand. The market demand in the US region is very strong and has been in short supply. The US region also needs to import products from other countries to meet its own needs.

Moreover, in Europe and other developed countries and regions, the production technology of ultra high molecular weight polyethylene fiber (a href= "//www.sjfzxm.com/news/index_c.asp" > bulletproof vest, bullet helmet and other protective products) is relatively mature in this area.

At present, the consumption structure of UHMWPE fiber is: Europe and the United States mainly use bulletproof vest and weapons and equipment, accounting for about 60% to 70% of the total, followed by rope, about 20%, fishing nets and so on, about 5%, and labor protection products account for about 5%.

Japan is mainly used for ropes, fishing nets and protective clothing, especially anti cutting gloves. It has reached the level of over 25% of the total demand of UHMWPE fibers in automobile production process.

However, the amount of UHMWPE fiber used in our country is not high abroad.

China is a large consumer market for UHMWPE fiber.

For example, Jian Qiao technology Jiangsu Co., Ltd. produces an annual output of 3200 tons of ultra-high molecular weight polyethylene fiber project, investing 1 billion yuan to build 10 ultra-high molecular weight polyethylene fiber production lines, 2 weft free production lines and 1 annual production of 100 thousand bulletproof vest production lines.

After the project is completed and put into operation, it can achieve annual sales revenue of 970 million yuan and various taxes of 100 million yuan.

The products of the company should be put on the basis of every demand field in the domestic market, and strive to export products to the developed countries, such as the United States, which are in short supply to win higher profits, and enable China's high-performance products to go abroad.

< p > > a href= "//www.sjfzxm.com/news/index_c.asp" > super high molecular weight < /a > polyethylene fiber has a bright future, because UHMWPE fiber has an unusual high strength "character".

A stainless steel scissors cut the UHMWPE fiber, and the knife edge will be passivated after one continuous shearing.

In addition, the free fracture length of UHMWPE fibers in water is infinitely long. Under the same thickness, it can withstand 8~10 times the maximum mass of wire rope. The strength of UHMWPE fiber is 15 times higher than that of steel.

If it is calculated by mass, its strength is 40% higher than that of aramid fiber. It can be called the highest strength fiber in the world today.

Therefore, it has become the third generation of ultra-high strength fibers after carbon fiber and aramid fiber.

In the international market, the main application fields of UHMWPE fiber and its composite products include: Defense munitions, such as aircraft, tanks, armored vehicles and all kinds of chariots, ships, light bulletproof armor plates; safety protection, such as lightweight bulletproof vests, lightweight bulletproof helmets, anti stab clothes, anti cut clothing fabrics, anti cutting gloves, etc.

Back in July 27, 2012, we learned that Jiangsu's R & D strength is higher than that of steel reinforced UHMWPE fibers.

The ultra high molecular weight polyethylene fiber developed by the company is 15 times the strength of steel bar, and it is one of the new material industries that are mainly developed by the state.

High strength polyethylene fiber has good impact resistance and large energy absorption, and can be made into protective clothing, helmet and bulletproof materials in military field, such as tank protective board, protective cover of radar, missile cover, bulletproof vest, etc.
