本文提出了一种准确快速易掌握的测定氧化钠和二氧化硅的方法,该方法的测定结果和标准样进行对比,结果相吻合。工业硅酸钠广泛用于作板纸、木材、铸造、耐火材料等工业的胶粘剂、合成洗涤剂的助剂、制皂业添充料同时也是重要的化工原料,在应用中随着使用的不同,对产品的氧化钠和二氧化硅的含量和比值(模数)要求也不同,所以氧化钠和二氧化硅的比值和含量是比较重要的指标。
This paper presents an accurate and rapid determination of sodium oxide and silica method, the method of determination and standard samples were compared, the results are consistent. Sodium silicate is widely used in industrial paperboard, wood, casting, refractory and other industrial adhesives, synthetic detergent additives, soap additives is also an important chemical raw materials, in the application with the use of different , The product of sodium oxide and silica content and the ratio (modulus) requirements are different, so the ratio and content of sodium oxide and silica is a more important indicator.
