Factory Supply Bis-(sodium sulfopropyl)-disulfide (SPS) with the CAS number 27206 - 35 - 5 is a high - quality chemical product. It is often supplied at the best price from reliable factories.
Fórmula química: C₆H₁₂Na₂O₆S₄
Peso molecular: Approximately 354.39 g/mol
Aparência: Usually presents as a white to off - white powder or granular solid.
Solubilidade: It is highly soluble in water, which makes it convenient for various applications.
Indústria de galvanoplastia: SPS is widely used as a brightening agent in electroplating processes. It can improve the brightness, smoothness, and uniformity of the electroplated layer. For example, in copper electroplating, it helps to achieve a high - quality copper coating on the substrate, which is essential for printed circuit boards (PCBs), decorative plating, and other metal finishing applications.
Tratamento da água: In water treatment, SPS can be used as a reducing agent or a stabilizer. It can react with certain heavy metals and other pollutants in water, helping to remove or reduce their concentrations, thereby purifying the water quality.
Indústria têxtil: It can be used in some textile dyeing and finishing processes. It may act as a leveling agent or a modifier to improve the color fastness and uniformity of the dyed textiles.
Electroplating: In electroplating baths, the dosage of SPS typically ranges from 0.1 - 1.0 g/L, depending on the specific electroplating requirements such as the type of substrate, the desired plating thickness, and the electroplating equipment used. First, dissolve the appropriate amount of SPS in a small amount of water, and then add it slowly to the electroplating bath with continuous stirring to ensure uniform distribution.
Tratamento da água: When used in water treatment, the dosage needs to be determined according to the water quality analysis results. Usually, it is added in the form of an aqueous solution. The water should be well - mixed after adding SPS to ensure effective reaction with pollutants.
Indústria têxtil: For textile applications, SPS can be added during the dyeing or finishing process. The dosage is usually based on the weight of the textile materials and the specific process requirements. It is recommended to conduct small - scale trials first to optimize the dosage and process conditions.
Case 1: PCB Electroplating
A PCB manufacturing company was facing issues with uneven copper plating on their boards. After adding 0.5 g/L of SPS to their electroplating bath, they noticed a significant improvement in the plating quality. The copper layer became brighter, smoother, and more uniform. This not only improved the electrical performance of the PCBs but also reduced the rejection rate during the quality inspection process, resulting in cost savings and increased production efficiency.
Case 2: Industrial Wastewater Treatment
An industrial factory was struggling with high levels of heavy metals in their wastewater. By adding an appropriate amount of SPS as a reducing agent, they were able to reduce the heavy metal concentrations to within the allowable discharge limits. The treated water could then be safely discharged or reused in some non - critical processes, reducing the environmental impact and water resource consumption.
Case 3: Textile Dyeing
A textile dyeing factory was experiencing color variation in their dyed fabrics. After incorporating SPS as a leveling agent at a dosage of 0.2% based on the weight of the fabric, the color fastness and uniformity of the dyed textiles were greatly enhanced. Customers were more satisfied with the product quality, and the factory was able to gain a better market reputation.
