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.農(nóng)業(yè)：它能為植物提供相應(yīng)的營(yíng)養(yǎng)，改變土壤的性質(zhì)。將土壤顆粒中的磷和微量元素釋放到土壤的溶液中。提高植物對(duì)水的利用率。減少植物的蒸騰作用，提高土壤水分的吸收效率。減少植物在土壤溶液或灌溉水中對(duì)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.卷煙工業(yè)作為煙草的助燃劑，制藥工業(yè)作為青霉素的培養(yǎng)基。

2. Cigarette industry is used as combustion supporting agent of tobacco and pharmaceutical industry as culture medium of penicillin.

3.混凝土：作為混凝土外加劑，能提高混凝土的早期強(qiáng)度。防止鋼材腐蝕。防止混凝土在冬季施工中凍害。

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.脫色：它主要用于清理原料中雜質(zhì)對(duì)玻璃產(chǎn)生的不好顏色，使其無色透明?；瘜W(xué)脫色劑主要有化學(xué)脫色劑和物理脫色劑兩種，其中化學(xué)脫色劑通常通過氧化脫色。

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.防銹：它具有較強(qiáng)的氧化性，能使金屬陽極鈍化，并在表面形成致密的氧化膜防銹。為了在短時(shí)間內(nèi)使鋼材表面潔凈，關(guān)鍵是選擇硝酸鈉的濃度。減少濃度既能保持較高的三氯化鐵含量，又不易飽和，從而較好地解決鋼鐵產(chǎn)品的酸洗質(zhì)量問題。

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.食品工業(yè)：食品工業(yè)在肉類加工中用作著色劑，可以防止肉類變質(zhì)，起到調(diào)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.

該產(chǎn)品應(yīng)用比較廣，可以說涉及生活的許多角落，為現(xiàn)代發(fā)展提供了便利，建立了價(jià)值。但由于危險(xiǎn)性大，所以生產(chǎn)中要做好各方面的防護(hù)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.
