Leather tanning is an ancient craft that transforms raw animal hides into durable and versatile material. One of the key components in modern leather tanning processes is sodium chlorite (NaClO2). In Brazil, a country known for its rich leather industry, the use of sodium chlorite has gained prominence due to its efficiency and eco-friendly nature. This article explores the application of 80% sodium chlorite in the tanning of leather in Brazil.
Brazilian Leather Market Situation
In 2021, Brazil will continue to be the global beef hegemony with an export volume of more than 2 million tons. 60% of the leather produced will be supplied to the automobile industry and the furniture industry, and the rest will be supplied to the handicraft production, clothing and shoe industries. From January to September 2022, the target markets for Brazilian leather exports are mainly Italy, accounting for 27.21%, an increase of 26% over the same period last year; China, accounting for 23.35%, an increase of 47% over the same period last year;HK accounting for 11.32%, an increse of 12% growth over the same period.
However, the production of leather requires a depilatory agent, and sodium chlorite 80 percent is the best choice. Sodium chlorite 80 percent has a huge sales volume in the Brazilian market, mainly imported from Hong Kong and mainland China.
The Role of Sodium Chlorite in Leather Tanning
Sodium chlorite, a powerful oxidizing agent, plays a crucial role in the leather tanning process. It aids in removing hair, flesh, and unwanted proteins from animal hides, preparing them for further processing. The chemical's efficiency in dehairing and deliming leather makes it a preferred choice for tanneries seeking a sustainable alternative to traditional tanning methods.
Advantages of Sodium Chlorite in Leather Tanning
Sodium chlorite offers a greener alternative to traditional tanning methods that involve harsh chemicals. Its oxidizing action breaks down unwanted organic matter without leaving toxic residues, minimizing environmental impact.
Reduced Water Consumption:
Compared to conventional tanning processes, the use of sodium chlorite typically requires less water. This efficiency contributes to conserving water resources and reducing overall water consumption in leather production.
Shorter Tanning Time:
The use of 80% sodium chlorite solutions often leads to a shorter tanning time compared to conventional methods. This translates to increased productivity and reduced energy consumption in tanneries.
Improved Leather Quality:
Sodium chlorite's efficient deliming and dehairing capabilities result in better-quality leather. The treated leather exhibits uniformity, enhanced softness, and better dye absorption, meeting the demands of the fashion and upholstery industries.
Safer Working Environment:
Sodium chlorite solutions, when handled properly, pose fewer health risks to tannery workers compared to some traditional tanning agents. Adequate safety measures and training are still necessary to ensure safe handling.
Regulatory Compliance and Safety Measures
In Brazil, the use of sodium chlorite in the leather tanning industry is subject to strict regulatory compliance. Tanneries must follow guidelines issued by regulatory authorities to ensure the safe and responsible use of the chemical. Safety measures, such as the use of protective equipment, proper storage, and adequate ventilation, are mandatory during its application.
The adoption of sodium chlorite (80%) in the tanning of leather in Brazil has become an essential aspect of the country's vibrant leather industry. Its eco-friendly properties, reduced water consumption, and improved leather quality make it a valuable component in modern tanning processes. As the demand for sustainable and efficient leather production continues to grow, sodium chlorite's role in the Brazilian leather industry is expected to remain significant, contributing to a greener and more efficient tanning sector.
