Adopting one-step synthesis process, the effective impurity content is controlled below the national standard limits, with a purity of up to 98.5% and excellent chemical stability. The anhydrous form contains no crystal water, so it will not generate bubbles or dilute the reaction system due to water evaporation in high-temperature reaction environments, adapting to precise chemical synthesis and high-temperature printing and dyeing color fixing scenarios. The moisture-proof kraft paper bag packaging effectively prevents moisture agglomeration and ensures product activity. It can be used as a buffer agent in the electroplating industry to stabilize the pH value of the electroplating solution and improve the quality of the coating. Compared with water-containing products, the active ingredient per unit weight is increased by about 40%, reducing transportation and storage costs.
Particle size: 0.42-0.85mm; Moisture content: ≤0.3% (superior grade); Free acid (calculated as acetic acid): ≤0.05%; Sulfate content: ≤0.03%; Bulk density: 0.85-0.95g/cm³; Dissolution speed: completely dissolved in water at 25℃ within 5 minutes; Packaging specification: 25kg moisture-proof kraft paper bag or 1000kg ton bag (pallet optional); Storage conditions: ventilated and dry warehouse, away from acidic substances; Shelf life: 18 months.
It is applicable to cotton fabric dyeing and color fixing in printing and dyeing industry, preparation of organic intermediates in chemical synthesis, pH buffer adjustment in electroplating industry, tanning auxiliary in leather processing, carbon source supplement in sewage treatment (partial scenarios), cement grinding aid in construction and other scenarios. It can effectively improve the stability of industrial production and product quality, reduce the generation of by-products during production, and is an indispensable basic chemical raw material in industrial production.
