硝酸钠的应用领域和注意事项是什么?

发布来源:http://www.jinhao360.com    更新时间:2020-05-05 点击数:

  硝酸钠是无色透明或白色微带黄色钻石晶体,其味苦咸,溶于水、液氨,微溶于甘油和乙醇,易潮解,特别是在非常少量氯化钠杂质,硝酸钠潮解大大增加,当溶解在水中当溶液温度降低,解决方案是中性的,当加热时,硝酸钠容易分解成亚硝酸钠和氧气。那么,硝酸钠的应用领域和注意事项是什么呢?下面恒毅化工将给您分享,一起来看!

  Sodium nitrate is a colorless transparent or white micro strip yellow diamond crystal, which tastes bitter and salty, soluble in water and liquid ammonia, slightly soluble in glycerin and ethanol, and easy to be deliquesced, especially in a very small amount of sodium chloride impurities, the deliquesce of sodium nitrate is greatly increased, when dissolved in water, when the solution temperature is reduced, the solution is neutral, when heated, sodium nitrate is easy to be decomposed into sodium nitrite and oxygen. So, what are the application fields and precautions of sodium nitrate? Hengyi chemical will share with you and look at them together!
  硝酸钠的应用
  Application of sodium nitrate
  1. 搪瓷工业主要用作搪瓷粉的助熔剂、氧化剂和原料。
  1. Enamel industry is mainly used as flux, oxidizer and raw material of enamel powder.
  2. 玻璃工业用于各种玻璃及制品的脱色剂、消泡剂、澄清剂和氧化助熔剂。
  2. The glass industry is used as decolorizer, defoamer, clarifier and oxidation flux for all kinds of glass and products.
  3.非饥饿工业是作为脱色剂用于熔融烧碱和其他硝酸盐的制造。
  3. Non starvation industry is used as decolorizer in the manufacture of molten caustic soda and other nitrates.
  4、食品行业作为肉类加工的代理商,可以防止肉类变质,并能起到调味的作用。
  4. As an agent of meat processing, food industry can prevent meat from deteriorating and play a role of seasoning.
  5. 化肥工业被用作酸性土壤的速效肥料,特别是用于甜菜和萝卜等块根作物。染料工业被用作生产苦味酸和染料的原料。
  5. Fertilizer industry is used as quick acting fertilizer for acid soil, especially for root crops such as beet and radish. The dye industry is used as a raw material for the production of picric acid and dyes.
  6. 适用于钢铁、铝合金、冶金等行业的热处理。机械城工业作为金属清洗剂和黑色金属蓝剂的制备。
  6. Suitable for heat treatment of steel, aluminum alloy, metallurgy and other industries. Mechanical city industry is used as the preparation of metal cleaning agent and black metal blue agent.
  7. 制药业把它用作青霉素的培养基。卷烟工业被用作烟草的促进剂。
  7. The pharmaceutical industry uses it as a culture medium for penicillin. The cigarette industry is used as an accelerant of tobacco.
  8. 在分析化学中,它被用作化学试剂。此外,它还用于生产炸药。
  8. In analytical chemistry, it is used as a chemical reagent. It is also used in the production of explosives.
  硝酸钠的使用
  Use of sodium nitrate
氢氧化钾
  硝酸钠在水处理领域主要用作缓蚀剂、锅炉金属脆化抑制剂。硝酸钠作为金属脆化抑制剂时,应与氢氧化钠配合使用,并保持一定比例。在低压锅炉系统中加入硝酸钠可以防止金属材料的脆化。此外,其他领域也得到了广泛的应用。
  Sodium nitrate is mainly used as corrosion inhibitor and boiler metal embrittlement inhibitor in the field of water treatment. When sodium nitrate is used as the inhibitor of metal embrittlement, it should be used together with sodium hydroxide and keep a certain proportion. Adding sodium nitrate to the low pressure boiler system can prevent the embrittlement of metal materials. In addition, other fields have also been widely used.
  硝酸钠可以防止食物变质,保证安全食用。大剂量可用于杀虫剂和杀鼠剂。此外,硝酸钠还有许多工业用途,包括化肥、光化学和金属铸造工业。
  Sodium nitrate can prevent food from spoilage and ensure safe consumption. Large doses can be used in insecticides and rodenticides. In addition, sodium nitrate has many industrial uses, including chemical fertilizer, photochemistry and metal casting industry.
  硝酸钠也是一种用于生产化肥、炸药和火箭推进剂的盐。硝酸钠的使用还包括作为防腐剂保存肉类。硝酸钠具有抗菌特性,可以防止腐肉中毒,许多人可能不知道一些绿叶蔬菜也含有大量的硝酸钠。
  Sodium nitrate is also a salt used in the production of fertilizers, explosives and rocket propellants. The use of sodium nitrate also includes preservation of meat as a preservative. Sodium nitrate has antibacterial properties and can prevent carrion poisoning. Many people may not know that some green leafy vegetables also contain a lot of sodium nitrate.
  众所周知,硝酸盐和亚硝酸盐与心血管疾病密切相关,而过量食用加工肉类,如火腿和香肠,则与高血压和动脉硬化等心血管疾病有关。专家警告说,食用过多的含硝酸钠的肉类也会导致偏头痛。
  As we all know, nitrate and nitrite are closely related to cardiovascular diseases, while excessive consumption of processed meat, such as fire legs and sausages, is related to cardiovascular diseases such as hypertension and arteriosclerosis. Experts warn that eating too much meat with sodium nitrate can also cause migraines.
  硝酸钠最初开采于智利的阿塔卡马沙漠,这是地球上最干燥的沙漠。阿塔卡马也是矿产最丰富的地区之一。尽管硝酸钠对健康有负面影响,但缺乏硝酸钠会使肉类难以储存和运输,容易变质。
  Sodium nitrate was originally mined in Chile's Atacama Desert, the driest desert on earth. Atacama is also one of the most mineral rich areas. Although sodium nitrate has a negative impact on health, the lack of sodium nitrate will make meat difficult to store and transport, and easy to deteriorate.
