In 2021, the Electronic grade plant was expanded, and the production capacity will be expanded to 9,000t/a; the production capacity of industrial-grade dicyandiamide will be expanded from 40,000t/a to 47,000t/a.

In 2020, the automatic production line of calcium cyanamide rotary kiln in the second district will be built.

In 2019, a 40T circulating fluidized bed boiler will be rebuilt and expanded as a heat source for the Great Wall Park in the Economic and Technological Development Zone.

In 2018, a new process was adopted to use liquid carbon dioxide instead of lime kiln gas to produce dicyandiamide.

In 2017, the 1# DCDA plant was technically upgraded, and the production capacity was expanded from 11,000 t/a to 18,000 t/a.

In 2016, the refining plant was expanded and the production capacity was expanded to 4,000t/a.

In 2012, our dicyandiamide production line adopted a vacuum suction filter instead of the sand filter, and a new production line with an annual output of 20,000 tons of dicyandiamide was built.

In September 2009, our dicyandiamide production scale was expanded to 11,000 t/a, and the calcium cyanamide production scale was expanded to 120,000 t/a.

Our company was established on July 24, 2003, with a production scale of 30,000 t/a of lime, 5,000 t/a of dicyandiamide, 1,000 t/a of electronic grade dicyandiamide, and 40,000 t/a of calcium cyanamide.
