Application
Leather Tanning
The Chrome Sulphate is the main auxiliary agent in the chrome tanning process. It can effectively crosslink with the collagen fibers in animal skins, enhancing the durability, flexibility, water resistance and thermal stability of leather. Compared with vegetable tanning, this process significantly improves the quality and service life of leather.
Pigment Production
Our products are precursors for the production of chromium-based pigments. These pigments have excellent color fastness and chemical resistance and are suitable for paints, coatings, plastics and inks.
Metal Treatment
Chromium sulfate is used in electroplating and metal surface treatment to deposit a protective chromium layer and enhance the corrosion resistance and surface hardness of the metal.
Catalyst Preparation
In the chemical industry, it is used to produce chromium-containing catalysts to promote various organic reactions, including oxidation and polymerization processes.
Water Treatment
It has a wide range of applications in wastewater treatment, especially in the removal of certain pollutants by chemical precipitation.
Storage and transportation
The warehouse should be low temperature, ventilated, dry; fireproof; stored separately from strong oxidants
Marketing
Our products are sold well in more than 60 countries and regions including North America, Western Europe, Southeast Asia, Central and South America, etc. We have established long-term and stable cooperative relations with pharmaceutical companies in Europe, the United States, Greece, Germany, Iran, Russia, South Korea, India and other countries.
