Recently, Sinochem International said in a recent institutional survey that the company's 40,000 tons/year nylon 66 and 25,000 tons/year hexanediamine plants have been in the process
of optimizing production lines, marketing and gradually increasing volume to meet different customer needs since they were put into operation in June 。 At present, the operation of the device exceeds the level of small test and pilot test, the operation of the device is stable, the cost and quality are comparable to the industry head enterprises, hexamethylenediamine and nylon 66 chips have been officially sold, hexamethylenediamine has achieved a balance between production and sales, nylon 66 has been sold more than 1,000 tons per month, and has achieved profitability since September, and it is expected that the project can bring new sales revenue of 886 million yuan to the company every year after reaching production and effect, and an annual net profit of nearly 100 million yuan
.
On May 5 this year, Ningxia Ruitai Technology Co.
, Ltd.
nylon 66 new material project was successfully started up at one time, which is the first caprolactam-hexanediamine-nylon 66 device
in China.
The main raw materials of nylon 66 are adipic acid and hexanediamine
.
The caprolactam to hexamethylenediamine process is the production of aminoahexanenitrile between caprolactam and ammonia under the action of a catalyst, and then hydrogenation of aminohexanediamine to obtain hexamethylenediamine
.
Ningxia Ruitai Technology Co.
, Ltd.
nylon 66 new material project includes an annual output of 40,000 tons of nylon 66 and an annual output of 25,000 tons of hexamethylene diamine production plant, which is a key project unveiled by Ningxia Autonomous Region, with a total investment of 980 million yuan, which started construction in April 2021 and completed construction in February 2022
.
Rite-Hite's 25,000-ton hexanediamine production unit is a two-step reaction preparation of continuous catalysis and hydrogenation.
It is understood that the nylon 66 production capacity of Ningxia Ruitai Technology Co.
, Ltd
.
will be expanded to 80,000 tons / year in 2023, and will be further expanded to the domestic head production capacity in combination with technology and market conditions in the future.
