Xinri Hengli: Bio-based, starch-based new material manufacturing - long-chain dibasic acid

TK bio-based materials report: Recently, Xinri Hengli released the 2022 semi-annual board of directors' business review, and some relevant content are as follows
.

According to the "National Economic Industry Classification" (GB/T4754-2017), the company's holding subsidiary Zhongke New Materials sub-sectors belong to C manufacturing industry - 28 chemical fiber manufacturing industry - 283 bio-based material manufacturing - 2832 bio-based, starch-based new materials Material Manufacturing - Long Chain Dibasic Acids (Biological Extraction) (Classification Code C2832)
.

Long-chain dibasic acids usually refer to organic compounds with carboxyl groups at both ends of the straight carbon chain.
Dibasic acids with more than ten atoms on the carbon chain are usually called long-chain dibasic acids
.
The production methods of long-chain dibasic acids are divided into chemical methods and biological methods
.
The traditional market is dominated by chemical production.
The core production technology is in the hands of a few developed countries such as the United States and Germany.
The production conditions are harsh and the environmental pollution is serious
.

Since the 1970s in China, the Institute of Microbiology, Chinese Academy of Sciences, under the leadership of Academician Fang Xinfang, has carried out research on the production of long-chain dibasic acids by microbial fermentation.
The protoacid technology has finally formed an emerging green chemical industry with Chinese characteristics and independent intellectual property rights.
China has become the only country in the world that can use biological methods to produce long-chain dibasic acids on a large scale
.
Compared with the traditional chemical method, the biological method has mild production conditions, normal temperature and normal pressure production, is environmentally friendly, has no major risk sources, and has low production costs
.
In recent years, with the continuous improvement of domestic and foreign requirements for green development, biological long-chain dibasic acid products have dominated the market by virtue of production technology and other advantages
.

As one of the main products of bio-based new materials, long-chain dibasic acids are widely used in dozens of high-tech material industries such as high-end energy, new energy vehicles, chemical industry, light industry, agriculture, medicine, liquid crystal materials, military industry, aerospace and so on.
, its application field is mainly for the production of long carbon chain polyamide, and is suitable for high-grade hot melt adhesives, cold-resistant plasticizers, surface treatment agents, high-grade lubricating oils, synthetic fragrances and other fields, and downstream derivatives of long-chain dibasic acids.
There are many, and the consumption structure shows a trend of diversification
.

During the "14th Five-Year Plan" period, China's long-chain nylon industry will focus on the requirements of lightweight, high wave transmittance, high strength, high temperature resistance, and sealing in the fields of automobile lightweight, home appliance intelligence, and electronic and electrical miniaturization.
Innovate and develop, and launch new products and new technologies that are in line with the rapid development of the industry
.

With the uncertainty of the Sino-US trade war, the entire long-chain nylon industry will also increase the localization rate of raw material processing and testing equipment.
It is expected that during the "14th Five-Year Plan" period, the localization rate of related raw materials and equipment will increase significantly , With the expansion of long-chain nylon and other industries as one of the main production raw materials of long-chain nylon, the market share of long-chain dibasic acid will continue to grow in the future, and the overall market demand will further increase
.

Main business of Xinri Hengli

The main business of the company's holding subsidiary Zhongke New Materials is the production and sales of long-chain dibasic acids.
The company's third-generation biological method for large-scale production of long-chain dibasic acid technology uses water-phase extraction and purification technology.
No organic solvents are used in the production process.
, to avoid the pollution of organic solvent volatilization to the environment and the corresponding carbon emissions, in line with the requirements of national technology and industrial policies
.
At present, the product is in the stage of market cultivation and expansion
.
The company adheres to the market demand-oriented, through continuous technological research and development and production technology progress, continuously improves product quality according to user needs, and further strengthens the company's profitability
.

Analysis of Xinri Hengli's Core Competitiveness

Zhongke New Materials has the third-generation biological method long-chain dibasic acid large-scale production technology with independent intellectual property rights, with the characteristics of "new strains, new raw materials, new processes", unique production strains and fermentation control technology The acid production efficiency of the fermentation unit has reached a new level in the industry; the unique water-phase extraction and purification process has no organic solvent pollution in the entire production process, and the production process is clean and environmentally friendly; it has been verified that the water-phase extraction and purification process can produce products that meet the needs of users, and further reduce Production cost; the working conditions of the self-designed fermentation reactor meet the process control requirements after the new process and new technology are scaled up, and through continuous optimization to further improve product quality and reduce product cost, it is conducive to improving product competitiveness
