Sodium Hydrosulfite

Product Introduction

Sodium Hydrosulfite, also known as sodium dithionite, is a crucial chemical in the paper and pulp industry. It serves primarily as a bleaching agent and reducing agent, making it invaluable for processes requiring decolorization or reduction of oxidized compounds. In East Africa, Kivi Chemicals supplies Sodium Hydrosulfite to various industries, ensuring high-quality standards and compliance with local regulations. Its ability to effectively remove color from pulp and paper products enhances the production of bright, high-quality paper, making it a preferred choice among manufacturers in Kenya, Uganda, Tanzania, and beyond.

Detailed Product Overview

Sodium Hydrosulfite, with the chemical formula Na2S2O4, is a potent reducing agent commonly used in various industrial applications. As a white crystalline powder, it is easily identifiable and has a molecular weight of 190.11 g/mol. This compound is particularly valued for its ability to convert colored compounds into colorless ones, a property that is crucial for the bleaching processes in industries. Its solubility in water allows for easy integration into aqueous systems, enhancing its utility in processes that require a reducing environment. The product's neutral pH when in solution ensures that it does not adversely affect the pH balance of the systems it is introduced to, maintaining the integrity of the processes involved. In the paper and pulp industry, Sodium Hydrosulfite is primarily used for bleaching purposes, where it helps produce high-quality, white paper by reducing chromophores in the pulp. It is also extensively utilized in the textile industry for vat dyeing and stripping, where its reducing properties enable effective color removal and the preparation of fabrics for dyeing. Additionally, Sodium Hydrosulfite finds applications in food processing as a bleaching agent and in chemical manufacturing as a reducing agent for various chemical reactions. Its versatility and effectiveness make it an essential component in these industries, particularly in East Africa, where such processes are prevalent. The Sodium Hydrosulfite supplied by Kivi Industrial Chemicals Limited is of industrial grade, with a minimum purity of 88%, ensuring its effectiveness in demanding industrial applications. Buyers should verify the purity and moisture content, which should not exceed 5%, upon receipt to ensure compliance with process requirements. The product's appearance as a white crystalline powder and its density of 1.2 g/cm³ are key indicators of its quality. It is packaged in 50 kg polypropylene bags, offering ease of transportation and handling. Ensuring the product meets these specifications is crucial for maintaining process efficiency and achieving desired outcomes. Proper handling and storage of Sodium Hydrosulfite are imperative to maintain its efficacy and safety. The product should be stored below 25°C in a dry, well-ventilated area to prevent degradation and moisture absorption, which could compromise its performance. As it is a reducing agent, it should be kept away from oxidizing agents and sources of ignition. Sodium Hydrosulfite is classified under UN1384, and appropriate precautions should be taken to adhere to safety regulations during transportation and storage. Kivi Industrial Chemicals Limited ensures that their packaging and supply chain processes align with industry standards, providing a reliable supply to meet the needs of the East African market.
