This product is 99% content light soda ash (sodium carbonate) powder, supplied in large-capacity ton bags (also known as FIBCs). It is designed specifically for large-scale, continuous production industries like glass manufacturing and dyeing, aiming to reduce unit packaging costs and improve loading/unloading and dosing efficiency. In the glass industry, soda ash is the second most crucial raw material after silica sand, renowned as the "fluxing agent for glass." In glass furnaces operating at temperatures up to 1500°C, the sodium oxide generated from the thermal decomposition of soda ash effectively disrupts the stable silicon-oxygen network structure of silica sand (silicon dioxide), significantly lowering its melting point. This allows the glass batch to melt into a homogeneous glass melt at lower energy consumption. Typically, producing one ton of flat glass or container glass requires approximately 0.2 tons of soda ash. The precision of its dosage and the stability of its quality directly impact the glass's transparency, strength, weatherability, and the incidence of defects like bubbles and stones during production. In the dyeing and printing industry, soda ash is equally indispensable as a "pH regulator" and "color fastness enhancer." Whether in the pre-treatment scouring of cotton fabrics (removing natural impurities and waxes) or during the reactive dyeing process, soda ash is needed to create and maintain a stable alkaline environment. In the scouring stage, alkalinity saponifies oils and emulsifies waxes; in the dyeing stage, it acts as a fixing agent, promoting the covalent bond formation between reactive dyes and cellulose fibers, thereby significantly enhancing dye uptake and color fastness (especially wash fastness). Our light soda ash powder features low bulk density and rapid dissolution characteristics. The ton bag packaging facilitates forklift handling and centralized storage, perfectly meeting the stringent requirements for raw material supply stability and cost-effectiveness in large-scale glass furnaces and automated dyeing production lines.
