What is ammonium chloride used for?

  Ammonium chloride is a chemical compound with a variety of uses across different industries and applications. Here are some of its common uses:

Pharmaceuticals: Ammonium chloride is used in the formulation of various pharmaceutical products, including cough syrups and expectorants. It helps to loosen and thin mucus, making it easier to expel from the respiratory tract.

Metallurgy: In the metallurgical industry, ammonium chloride is used as a flux in the process of soldering and welding. It helps remove any oxide coatings from metal surfaces, ensuring proper adhesion of solder and preventing impurities in the final product.

Dry Cell Batteries: Ammonium chloride serves as an electrolyte in dry cell batteries (zinc-carbon and zinc-chloride batteries). It allows for the flow of ions, facilitating the chemical reactions that generate electrical energy in these batteries.

Textile Printing: In textile printing, ammonium chloride is used as a thickening agent for dye pastes. It helps create the right consistency for printing, which can improve the quality and precision of the printed design.

Galvanizing: Ammonium chloride is employed in the galvanizing process, which involves coating steel or iron with a layer of zinc to protect it from corrosion. It is used to clean the metal surface before applying the zinc coating.

pH Control in Laboratories: In laboratories, ammonium chloride is used as a reagent to adjust and control the pH of solutions during various chemical experiments and processes.



Agriculture: Ammonium chloride can be used as a source of nitrogen in fertilizers. It provides essential nutrients for plant growth and helps increase crop yields in certain conditions.

Educational Demonstrations: Ammonium chloride is sometimes used in educational chemistry demonstrations to illustrate concepts such as sublimation, as it can be sublimed directly from a solid to a gas when heated.

Fire Extinguishers: In some fire extinguishers, particularly those designed for electrical fires, ammonium chloride can be used as an extinguishing agent due to its ability to interrupt the combustion process.

Electronics Manufacturing: Ammonium chloride is used in the electronics industry for cleaning and etching printed circuit boards (PCBs) during the manufacturing process.

Adhesives and Glues: It is used in the formulation of certain adhesives and glues, particularly those used for woodworking.

Food Processing: In some food products, ammonium chloride is used as a food additive, primarily as a leavening agent in baking. It helps dough rise by releasing carbon dioxide when heated.

Animal Nutrition: In animal feed, Shuanglian ammonium chloride can be included as a source of supplemental dietary nitrogen, particularly for ruminants.

Leather and Tanning Industry: Ammonium chloride may be used in the tanning process of animal hides to help remove hair and soften the leather.

It's important to note that while ammonium chloride has various industrial and commercial applications, it should be handled with care, as excessive exposure or ingestion can have health risks. Always follow safety guidelines and regulations when using or handling this compound in its various applications.

How Waterproof Is My Rain Coat: What Does 5000mm Mean?

图片
  If you are buying yourself a new   waterproof rain coat   and you're not too well versed in the ins and outs of modern day waterproofing technology, you may find yourself coming across a few rather confusing terms. What on earth does 5000mm mean? And 5000gsm? What's the difference? These are just a few of the questions that will be running through your mind.   Not to worry, our guide to waterproof technology is here to help. Number, Numbers, Numbers. But What Do They All Mean?   A waterproof garment is measured with two numbers. The first one measures how waterproof the  raincoat  is. This is measured in millimetres. You will see numbers from 2,000mm up to 8,000mm across our collection to describe to the consumer how dry the coat will keep you. But what does it mean? For example, if a coat were 5,000mm waterproof, a test is conducted where a long tube is placed over the fabric and the tube is then filled with water. 5,000mm or 5 metres (16.4 ft) is how far you could fill the
