Direct chloride and red crystal Henan

Dry cell batteries in the role of ammonium in everyday use is a zinc-manganese batteries, also known as carbon-zinc batteries, its structure is: do extremely negative zinc cylinder, made of tubular purpose is to store the electrolyte, etc. chemicals. The cathode is a carbon rod, it's surrounded by manganese dioxide, carbon powder and ammonium chloride mixture surrounded by water, it referred to as "carbon package." Filling the tube between the carbon-coated and zinc chloride was burnt, zinc chloride aqueous solution and starch composition, called electric burnt. Electric burnt in the main component of ammonium chloride, which is equivalent voltaic cell of dilute sulfuric acid solution. The role of electricity is burnt in the zinc chloride solution increases the concentration of zinc ions, zinc ammonium chloride tube mitigate corrosion and prolong battery life. Hot dip galvanizing process in the analysis of the role of ammonium chloride dip fluxing agents, also known as binding agents, can be maintained at a certain dip coating the workpiece before the activity, in order to enhance the coating and substrate. NH4Cl 15% ~ 25%, ZnCl2 2.5% ~ 3.5%, 55 ~ 65 ℃, 5 ~ 10min. To reduce NH4Cl volatile glycerin may be appropriate. Not the cooling water <50 ℃ ± zinc chloride may also be used in the detergent in what role A: It itself contains an acidic solution, dissolve metal oxides. The role played by the dissolution of oxide layers of a concentrated solution of ammonium chloride had a cloth soaked in detergent. Why can play fireproof ... A: concentrated ammonium chloride solution over a cloth soaked in it remains a lot of NH4Cl, the fire is NH4Cl thermal decomposition into NH3, HCl, is not burning gas, can play cut off oxygen to prevent the expansion of the role of fire use industrial-grade ammonium chloride uses mainly used in batteries, electroplating, dyeing, casting, medicine, flocking, fluff, chemical intermediates and so on.
