Sinochem International's nylon 66 project completed the mid-term handover of the plant, and it is expected to stabilize production in June

On April 6, Sinochem International, a central chemical enterprise, announced that the project with an annual output of 40,000 tons of nylon 66 and 25,000 tons of intermediate hexamethylene diamine, which was built by the company invested 978 million yuan, has completed the mid-term handover of the plant and is about to enter the commissioning stage.
Stable production was achieved in June this year
.

After the project is completed and put into production, it will rely on innovative production technology to effectively break through the "short supply" problem of China's nylon 66 and key intermediates, provide high-quality nylon 66 materials and key intermediate hexamethylene diamine products for the Chinese market, and improve China's nylon 66 materials.
66 The independent controllability of the industrial chain and the level of supply security
.

It is understood that the main raw materials of nylon 66 are adipic acid and hexamethylene diamine
.
Among them, adiponitrile, the key synthetic raw material of hexamethylenediamine, belongs to China's "stuck neck" product.
The slow development of domestic production capacity and the high price have become a major bottleneck restricting the development of nylon 66 industry
.

As an important platform for the material science sector of Sinochem in China, Sinochem International focuses on the field of national new materials to "make up for shortcomings".
After years of research and development, it has independently developed an innovative production process for hexamethylenediamine, and has introduced and absorbed and re-innovated aqueous solutions to form salts.
The continuous polymerization nylon 66 process technology has formed the first domestic process technology of "catalyst preparation - hexamethylene diamine synthesis - nylon 66 polymerization"
.

Cleverly bypassing the long-term monopoly of adiponitrile

This innovative production process uses bulk chemicals as raw materials and directly prepares hexamethylene diamine through a two-step reaction, cleverly bypassing the long-term monopoly of multinational companies on the technology and supply of adiponitrile, the key raw material of nylon 66
.
Compared with the traditional production process of hexamethylenediamine, it also has the advantages of easy availability of raw materials, less investment, no highly toxic chemicals such as hydrocyanic acid, and high level of safety and environmental protection
.

According to Sinochem International, the technology has been fully verified through small and pilot tests.
The key indicators such as the purity, chromaticity and polarographic value of the prepared hexamethylenediamine products are at the leading level in the industry, and the quality of nylon 66 products has also reached the industry-leading level.
requirements, and have the conditions for industrialization
.

In September 2020, Sinochem International, relying on the innovative production process of hexamethylenediamine, combined with the advantages of steam, natural gas and other energy sources in the western region, invested in the construction of a project with an annual output of 40,000 tons of nylon 66 and 25,000 tons/year of intermediate ethylenediamine in Zhongwei, Ningxia
.
The project is located in Sinochem Zhongwei Circular Economy Industrial Park.
Construction will start in April 2021, and it will be listed as a key project in Ningxia Autonomous Region in 2021
.

After the project is put into operation, it will bring new growth points to Sinochem International's performance
.
According to Sinochem International's forecast, after the project is put into operation, it will bring new sales revenue of 886 million yuan to the company every year, with a total annual profit of 99.
19 million yuan and an annual net profit of 84.
31 million yuan, which will further enhance Sinochem International's profitability.

.

According to the plan previously announced by Sinochem International, the company will focus on promoting "strengthening the chain, supplementing the chain and extending the chain" with the industrial chain thinking this year, expanding the existing advantages of core industries such as epoxy resin and polymer additives, and deepening the cultivation of ABS and aramid fibers.
, nylon 66 and other high-potential industrial chains
.
Now, the nylon 66 project is about to be put into production.
With the continuous advancement of other industrial chain projects, the company's competitiveness and industry status in the field of new chemical materials is expected to be significantly improved, which will also help to further enhance the company's valuation

Nylon 66 has become a high-prosperous track in the field of new materials in my country

Nylon 66 is widely used in the fields of high-end engineering plastics and high-end industrial fibers due to its high mechanical strength and good fiber elasticity, and has become a prosperous track in the field of new materials in China
.
In recent years, the state has also introduced various relevant policies to support the chemical industry and related enterprises to solve the problem of "insufficient rate of self-sufficiency" of nylon 66, and promote technological breakthroughs and industrial upgrading in the industrial chain
.

The "Industrial Structure Adjustment Guidance Catalogue (2019 Edition)" issued by the National Development and Reform Commission includes "polyamide fiber", "development and production of new polyamides such as long carbon chain nylon and high temperature nylon" and "10,000-ton-level adiponitrile production plant".
Encouraged; in the "14th Five-Year Plan" for the new chemical materials industry issued by the China Petrochemical Federation in May 2021, "special nylon" is also included in the "key development areas of new chemical materials"
.

In the market, the development space of nylon 66 and hexamethylene diamine is also generally optimistic
.
In 2021, China's nylon 66 consumption will be 615,000 tons
.
With the rapid development of new energy vehicles, textiles, coatings, electrical and electronic and construction industries, especially the promotion and popularization of lightweight and new energy vehicles, the consumer demand for nylon 66 will further increase
.
According to industry forecasts, the average annual growth rate of domestic nylon 66 consumption from 2021 to 2025 is about 7.
2%, and the market prospect is broad
