其實無水硫酸鈉指的就是硫酸鈉，無水硫酸鈉是硫酸根與鈉離子化合生成的鹽，一種無機化合物，那么您知道它的使用作用是怎樣的嗎？下面氫氧化鉀廠家為您講解。

In fact, anhydrous sodium sulfate refers to sodium sulfate. Anhydrous sodium sulfate is a salt formed by the combination of sulfate radical and sodium ion, an inorganic compound. Do you know how it works? The potassium hydroxide manufacturer will explain it to you.

1、化學工業用作制造硫化鈉硅酸鈉水玻璃及其它化工產品。

1. The chemical industry is used to manufacture sodium sulfide sodium silicate water glass and other chemical products.

2、造紙工業用于制造硫酸鹽紙漿時的蒸煮劑。

2. The paper industry is used as a cooking agent in the manufacture of kraft pulp.

3、玻璃工業用以代替純堿做助溶劑。

3. Glass industry is used to replace soda ash as cosolvent.

4、紡織工業用于調配維尼綸紡絲凝固劑。

4. The textile industry is used to prepare vinylon spinning coagulant.

5、用于有色金屬冶金、皮革等方面。

5. Used in nonferrous metal metallurgy, leather, etc.

6、用來制硫化鈉、紙漿、玻璃、水玻璃、瓷釉，也用作緩瀉劑和鋇鹽中毒的劑等。是用食鹽與硫酸制造鹽酸時的副產品。

6. It is used to make sodium sulfide, paper pulp, glass, water glass, enamel, as well as a laxative and an antidote to barium salt poisoning. It is a by-product of making hydrochloric acid with salt and sulfuric acid.

7、實驗室用于洗去鋇鹽。

7. The laboratory is used to wash away barium salts.

8、工業上用作制取NaOH和H?SO?的原料

8. Used in industry to produce NaOH and H? SO? Raw materials of

9、在有機合成實驗室硫酸鈉是一種為常用的后處理干燥劑。

9. Sodium sulfate is a commonly used post-treatment desiccant in the organic synthesis laboratory.

10、主要用作合成洗滌劑的填充料。

10. It is mainly used as the filler of synthetic detergent.

11、使水化產物硫鋁酸鈣更快地生成，從而加快了水泥的水化硬化速度。硫酸鈉的摻量一般為水泥質量的0.5%～2%，能提高混凝土早期強度50%～100%，28天強度有時提高，有時降低，提高幅度約在10%左右，隨水泥品種、養護條件及其摻量而異。

11. The hydration product calcium sulphoaluminate is generated more quickly, thus speeding up the hydration and hardening of cement. The dosage of sodium sulfate is generally 0.5%~2% of the cement quality, which can improve the early strength of concrete by 50%~100%. The 28 day strength sometimes increases, sometimes decreases, and the increase range is about 10%, which varies with the cement type, curing conditions and the dosage.

12、用作分析試劑，如脫水劑、定氮時消化催化劑，原子吸收光譜分析中干擾抑制劑。

12. It is used as an analytical reagent, such as a dehydrating agent, a digestion catalyst for nitrogen determination, and an interference inhibitor in atomic absorption spectrometry.

13、還用于洗滌劑和肥皂中作添加劑。

13. It is also used as an additive in detergents and soaps.

14、在硫酸鹽鍍鋅中可用作緩沖劑以穩定鍍液的ph值。

14. It can be used as a buffer in sulfate zinc plating to stabilize the ph value of the bath.
