硝酸鈉為中性，易受熱分解，具有助燃和氧化作用。因此，它有著廣泛的應用，同時作用也比較多。那么其作用主要表現在哪些方面呢？下面從八個方面來講講。

Sodium nitrate is neutral, easy to be decomposed by heat, and has the functions of combustion supporting and oxidation. Therefore, it has a wide range of applications, but also more functions. So what are the main aspects of its role? Here are eight aspects.

作用1：可用作助溶劑、氧化劑和制備搪瓷粉的原料。

Function 1: it can be used as cosolvent, oxidant and raw material for preparing enamel powder.

作用2：玻璃工業用作各種玻璃及其產品的脫色劑、消泡劑、澄清劑和氧化劑。

Function 2: used in the glass industry as decolorizer, defoamer, clarifier and oxidizer for various glasses and their products.

作用3：在機械工業中熔融燒堿和制造其他硝酸鹽無脫色劑。

Function 3: melting caustic soda and manufacturing other nitrates in the mechanical industry without decolorizer.

作用4：食品工業在肉類加工過程中使用它作為顯色劑，可以防止肉類腐爛，并起到調味作用。

Function 4: the food industry uses it as a chromogenic agent in the meat processing process, which can prevent meat from rotting and play a role in flavoring.

功能5：適用于酸性土壤中的肥料，尤其適用于甜菜、蘿卜等根莖作物。染色：用于苦味酸和染料的工業化生產。

Function 5: suitable for fertilizer in acid soil, especially for root crops such as beet and radish. Dyeing: used for industrial production of picric acid and dyes.

功能6：在機械城工業中用作金屬清潔劑，也用作黑色金屬的發藍劑。青霉素在制藥工業中的應用。卷煙工業被用作煙草的助燃劑。在分析化學中用作化學試劑。

Function 6: used as a metal cleaner in the machinery city industry, and also as a bluing agent for ferrous metals. Application of penicillin in pharmaceutical industry. The cigarette industry is used as a combustion supporting agent for tobacco. Used as a chemical reagent in analytical chemistry.

功能7：氫氧化鉀廠家認為硫酸鈉也可用于鎂合金涂層的低鉻酸鈍化和氧化溶液。

Function 7: sodium sulfate can also be used for low chromic acid passivation and oxidation solution of magnesium alloy coating.

功能8：在許多工業領域，硝酸鈉可以發揮一定的作用。因此，隨著其使用越來越廣泛，企業除了掌握正確的使用方法外，還應注意將其存放在陰涼通風的地方，因為它可以支持燃燒。

Function 8: sodium nitrate can play a certain role in many industrial fields. Therefore, as it is used more and more widely, in addition to mastering the correct use methods, enterprises should also pay attention to storing it in a cool and ventilated place, because it can support combustion.
