Industrialization of two core technologies of Pingmei Shenma

On November 26, China Pingmei Shenma Group Holdings Co.
, Ltd.
10,000-ton para-aramid project started the construction
of the first phase of the plant.
Previously, the first phase of the group's 500 tons/year silicon material project was put into operation
.
This marks that the group's two key core technologies, para-aramid and zone-melted polysilicon rod, have successively achieved breakthroughs and industrialization
.

Paraline is known as the "king of fibers", and carbon fiber, ultra-high molecular weight polyethylene fiber is known as the world's three major high-performance fibers, but the production technology has been in the hands
of a few foreign enterprises.
In 2005, Shenma Group (later merged into China Pingmei Shenma Group) started the research and development
of para-aramid.
In the absence of any technical reference, the scientific research team tested, summarized, improved, and tested again and again, and successively completed the construction of 500 tons/year polymerization device and supporting solvent recovery device, 100 tons/year spinning device, successfully opened up the production process, produced aramid fiber samples above 20 grams / denier level, and broke the screw continuous production resin technology, independently developed a para-aramid resin screw screw extruder, and improved the quality
of resin.

In the following years, the aramid pilot plant has been suffering from problems such as
unstable equipment operation and frequent fluctuations in product indicators.
Since this year, the research team has clearly divided the R&D topics into more than a dozen sub-topics such as polymerization, spinning, and control systems, and introduced the Objectives and Key Results Method (OKR) management model to carry out strong research
.
The research group has carried out more than 100 tests, solved more than 400 technical problems, formed more than 20 mature process technology solutions, and made a series of major breakthroughs
.
On October 25 this year, the group officially announced the successful research and development of para-aramid, and the product performance indicators reached the domestic advanced level
.

At the same time, the first phase of the group's 500 tons/year silicon material project was put into operation, which also broke the situation
of relying on imports for products.
Zone melting grade polysilicon is the key basic material for the preparation of integrated circuits, is a high-end product of electronic grade polysilicon, and its production technology has been mastered by developed countries such as the United States and Germany
.
In 2016, Henan Silane Technology Co.
, Ltd.
, a subsidiary of China Pingmei Shenma Group, began to develop regional melt-grade polysilicon, and after nearly 6 years of painstaking research, formed the core technology of independent industrial mass production, and the silane conversion rate reached more than
99%.
This technology has the characteristics of short process route and low reaction temperature, and the products produced have high purity, stability and good
quality.

In order to realize the industrialization of regional melt-grade polysilicon technology as soon as possible, Silane Technology Company launched the construction of a 500 tons/year semiconductor silicon material project (phase I project) in 2021, and successfully trial-produced on October 28 this year
.
At present, the first industrialized regional melt-grade polysilicon rod has been released from the production line, breaking the situation
of relying on imports of products.
