硝酸钠是众所周知的。其应用范围涵盖各个领域。作为一种工业盐，它具有食盐的特性。它在不同的应用范围中的作用？
Sodium nitrate is well known. Its application scope covers various fields. As an industrial salt, it has the characteristics of table salt. How does it work in different applications?
1.农业：它能为植物提供相应的营养，改变土壤的性质。将土壤颗粒中的磷和微量元素释放到土壤的溶液中。提高植物对水的利用率。减少植物的蒸腾作用，提高土壤水分的吸收效率。减少植物在土壤溶液或灌溉水中对氯的吸收。
1. Agriculture: it can provide corresponding nutrition for plants and change the nature of soil. Phosphorus and trace elements in soil particles are released into soil solution. Improve the utilization of water by plants. Reduce the transpiration of plants, improve the soil water absorption efficiency. Reduce the absorption of chlorine by plants in soil solution or irrigation water.
2.卷烟工业作为烟草的助燃剂，制药工业作为青霉素的培养基。
2. Cigarette industry is used as combustion supporting agent of tobacco and pharmaceutical industry as culture medium of penicillin.

3.混凝土：作为混凝土外加剂，能提高混凝土的早期强度。防止钢材腐蚀。防止混凝土在冬季施工中冻害。
3. Concrete: as concrete admixture, it can improve the early strength of concrete. Prevent steel corrosion. Prevent concrete from freezing damage in winter construction.
4.脱色：它主要用于清理原料中杂质对玻璃产生的不好颜色，使其无色透明。化学脱色剂主要有化学脱色剂和物理脱色剂两种，其中化学脱色剂通常通过氧化脱色。
4. Decolorization: it is mainly used to clean up the bad color of glass caused by impurities in raw materials, making it colorless and transparent. Chemical decolorizer mainly includes chemical decolorizer and physical decolorizer, among which chemical decolorizer is usually decolorized by oxidation.
5.防锈：它具有较强的氧化性，能使金属阳极钝化，并在表面形成致密的氧化膜防锈。为了在短时间内使钢材表面洁净，关键是选择硝酸钠的浓度。减少浓度既能保持较高的三氯化铁含量，又不易饱和，从而较好地解决钢铁产品的酸洗质量问题。
5. Antirust: it has strong oxidizability, can passivate metal anode, and form dense oxide film on the surface for antirust. In order to make the steel surface clean in a short time, the key is to select the concentration of sodium nitrate. Reducing the concentration can not only keep a high content of ferric chloride, but also not easy to saturate, so as to better solve the pickling quality problem of iron and steel products.
6.食品工业：食品工业在肉类加工中用作着色剂，可以防止肉类变质，起到调味作用。
6. Food industry: the food industry is used as a colorant in meat processing, which can prevent meat deterioration and play a seasoning role.
该产品应用比较广，可以说涉及生活的许多角落，为现代发展提供了便利，建立了价值。但由于危险性大，所以生产中要做好各方面的防护措施。
The product is widely used, it can be said that it involves many corners of life, provides convenience for modern development and establishes value. However, due to the high risk, so the production should do a good job in all aspects of protective measures.
