1. Ammonium chloride enters the body, and part of the ammonium ion bai is rapidly metabolized by the liver to form urea, which is excreted in urine. Chloride ions combine with hydrogen to form hydrochloric acid, thereby correcting alkalosis.
2. Due to the chemical irritation to the mucous membrane, the amount of sputum is increased reflexively, and the sputum is easily discharged, so it is beneficial to the removal of a small amount of mucus that is not easy to cough up. After this product is absorbed, chloride ions enter the blood and extracellular fluid to acidify the urine.
use with caution
(1) It is forbidden for patients with liver and kidney dysfunction. Use with caution when renal dysfunction is used to prevent hyperchloric acidosis.
(2) In patients with sickle cell anemia, it can cause hypoxia or (and) acidAmmonium chloride is poisonous.
(3) Contraindicated for patients with ulcer disease and metabolic acidemia.
(4) Prohibited for pregnant and lactating women
(5) Children use under the guidance of a doctor
is mainly used in dry batteries, batteries, ammonium salts, tanning, electroplating, precision casting, medicine, photography, electrodes, adhesives, yeast nutrients and dough improvers, etc. Ammonium chloride is abbreviated as “ammonium chloride”, also known as halogen sand. It is a kind of quick-acting nitrogen chemical fertilizer with a nitrogen content of 24% to 25%, which is a physiological acid fertilizer. It is suitable for wheat, rice, corn, rape and other crops, especially for cotton and linen crops, it has the effect of enhancing fiber toughness and tension and improving quality. However, due to the nature of ammonium chloride and if applied incorrectly, it will often bring some adverse effects to the soil and crops. Ammonium nitrate is generally used.
In addition, many foreign farms add ammonium chloride as an ammonium salt non-protein nitrogen to the feed of cattle and sheep, but the amount of addition is strictly limited.
can be used as chemical fertilizers, which are nitrogenous fertilizers, but ammoniated chemical fertilizers cannot be used together with alkaline chemical fertilizers, and it is best not to use them in saline soil to avoid reducing fertilizer efficiency.　Ammonium chloride is a strong acid and weak base salt, which releases acidity at high temperatures. Ammonium chloride is often used as a curing agent when casting hot core boxes to make cores. Its ratio: ammonium chloride: urea: water = 1:3:3.

Physical and chemical properties and uses 1. Ammonium chloride is a colorless cubic crystal with a salty taste and a specific gravity of 1.53. It has a melting point of 400°C and starts to sublimate when heated at bai100°C. It decomposes into ammonia and hydrogen chloride gas at 337.8°C. It is easily soluble in water and not easily It is soluble in alcohol, and the solubility in water increases significantly with the increase of temperature. The aqueous solution is acidic and corrosive to most metals.　　
2. Ammonium chloride is divided into dry ammonium and wet ammonium. The dry ammonium nitrogen content is 25.4%, and the wet ammonium nitrogen content is about 24.0%, which is higher than ammonium sulfate and ammonium carbonate; our company produces dry and wet ammonium chloride, because It is easy to absorb moisture and is easy to agglomerate. Therefore, in the production process, a small amount of loosening agent should be added to maintain its softness and convenient for users to use. During transportation, it is packed in double-layer polyvinyl chloride bags, which are well-closed, with a net weight of 50kg/bag; during storage and transportation, special attention should be paid to rain and moisture. Pay attention to scars after being broken, resulting in a large amount of product loss.　　
3. Ammonium chloride is a neutral fertilizer, suitable for most crops and some industries. Because it has the characteristics of slow nitrification, not easy to lose, long fertilizer efficiency, and high effective nitrogen utilization, it is often used in rice, corn, sorghum, wheat, cotton, hemp, vegetables and other crops, and can reduce crop lodging, rice blast, and rice blast. The occurrence of bacterial blight, root rot and other diseases has become the main source of nitrogen for compound fertilizer manufacturers; however, the quality of some crops will be affected by chloride ions, which is not suitable, such as tobacco, sweet potato, sugar beet, etc. Special note is treated differently.　　
4. In industry, ammonium chloride is mainly used in: batteries, metal welding, medicine, printing, dyes, precision casting and other industries.
