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(yīng)用，同時(shí)作用也比較多。那么其作用主要表現(xiàn)在哪些方面呢？下面從八個(gè)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(yè)用作各種玻璃及其產(chǎn)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(jī)械工業(yè)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(yè)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(diào)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(yè)化生產(chǎn)。

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(jī)械城工業(yè)中用作金屬清潔劑，也用作黑色金屬的發(fā)藍(lán)劑。青霉素在制藥工業(yè)中的應(yīng)用。卷煙工業(yè)被用作煙草的助燃劑。在分析化學(xué)中用作化學(xué)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(rèn)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(yè)領(lǐng)域，硝酸鈉可以發(fā)揮一定的作用。因此，隨著其使用越來越廣泛，企業(yè)除了掌握正確的使用方法外，還應(yīng)注意將其存放在陰涼通風(fēng)的地方，因?yàn)樗梢灾С秩紵?/div>
