As the chemical industry has gradually entered a stage of high-quality development in its transformation and upgrading, the dye industry has gradually established a full range of ecological, environmental and health concepts
.

In terms of products, companies and scientific research institutions first start from the source, vigorously produce environmentally friendly dyes, and carry out the substitution of carcinogenic aromatic amine dyes; in terms of clean production processes, companies actively develop new processes to replace traditional processes with serious pollution.
Reduce the discharge of "three wastes"; in terms of "three wastes" treatment, the enterprise strengthens terminal treatment, adopts membrane filtration and pure pulp drying to reduce the amount of waste water, and adopts MVR technology and multi-effect evaporation technology to treat waste acid and acid-containing waste water
.

In particular, the industry's leading companies have put more effort into green development
.

Taking Zhejiang Longsheng as an example, the company took the lead in the disperse dye industry to adopt the clean production process of salt-free diazonium agent, avoiding the problem of high acidity and difficult treatment of wastewater caused by the use of sodium nitrite, and reducing the acidity by more than 60%.

In the production of reactive dyes, Longsheng improves the selectivity of the reaction and controls the generation of by-products from the source by improving equipment, adopting suitable reaction catalysts, optimizing synthetic process routes, improving molecular structure, and improving the level of online detection and control
.

The synthesized product does not need to be salted out and washed with water, and the original slurry is sprayed directly, which basically realizes the "zero" discharge of process wastewater

Jihua Group, another giant in the dye industry, invested more than 600 million yuan to achieve green development.
It took 6 years to introduce the world's advanced continuous and intelligent production technology.
The important dye intermediate H acid produced by it has basically achieved the "three wastes" ""Zero" emissions

　　Runtu New Material Co.
, Ltd.
, a subsidiary of Runtu Co.
, Ltd.
, is one of the 38 emergency and anti-epidemic material manufacturers in Zhejiang Province
.
In order to fully fight the epidemic, Runtu New Materials insisted on non-stop production during the Spring Festival, ensuring quality and quantity production, canceling or reducing the normal sales of hydrogen peroxide and sodium hypochlorite, and giving priority to the free supply of epidemic areas and the surrounding areas of Shaoxing City, which effectively guarantees the availability of epidemic prevention and control materials Supply is dedicated to suppressing the virus and maintaining social stability
.

　　In terms of resuming work and production, dye companies have always upheld a responsible attitude, putting epidemic prevention and control and safe production first
