Inspired by hand-rolled noodles and noodles, this technology increases the production capacity of ultra-high molecular weight polyethylene by more than 10 times

When it comes to ultra-high molecular weight polyethylene, I believe that such a professional and abstract term, few people know what it is used for

However, the efficient and high-quality manufacture of UHMWPE products has always been a worldwide problem

·Initiate technical research on world problems·

"Ultra-high molecular weight polyethylene has many excellent properties, because its molecular weight is particularly large, which is ten or even hundreds of times that of ordinary polyethylene.

Artificial joint replacement is one of the effective means to treat femoral head necrosis, joint damage and other diseases caused by trauma, sports injury, degeneration and aging

Regrettably, due to the difficulty of processing UHMWPE, low production efficiency and high production cost, high-efficiency and high-quality manufacturing has become a major technical problem, and the materials and products of artificial joints are basically monopolized by foreign countries, which are expensive.

In 2016, with the support of the national key R&D program, the team of Academician Qu Jinping began to launch technical research on ultra-high molecular weight polyethylene

·Innovative processing methods to achieve efficient manufacturing·

"We initially envisaged using extensional rheological processing technology to solve the international problem of high-efficiency and high-quality manufacturing of ultra-high molecular weight polyethylene by changing the processing method

The international pioneering achievement "volume extensional rheological plasticization and transportation technology" led by Qu Jinping's team has completely subverted the traditional processing principle of polymer materials

Compared with the traditional technology, the new technology shortens the processing thermo-mechanical process by more than 50%, reduces the energy consumption by about 30%, has wide adaptability to materials, and greatly improves the performance of processed products, which is conducive to saving resources and protecting the environment

"On top of this, we can produce ultra-high molecular weight polyethylene products with high efficiency and high quality, thus forming a short-process and efficient manufacturing technology for ultra-high molecular weight polyethylene products, breaking through the technical barriers for large-scale promotion and application of products

·The production efficiency of the new technology is increased by more than 10 times·

The short-process and high-efficiency manufacturing technology of ultra-high molecular weight polyethylene products is a brand-new technology.

The emergence of new technologies has increased the production efficiency of ultra-high molecular weight polyethylene, which is extremely difficult to process, by more than 10 times

New technologies produce enormous economic and social benefits

In May last year, the intellectual property rights related to the technology were successfully implemented in Foshan at a transfer price of over 20 million yuan
