Zinc Chloride
General Information
USES
Dry Cell or Batteries:
Zinc chloride is commonly used in dry cell batteries
as an electrolyte where it also acts as a moisture absorbent and
corrosion inhibitor.
It
is an excellent water
soluble Zinc source for uses compatible with chlorides. Chloride
compounds can conduct electricity when fused or dissolved in water.
Electroplating :
Today, there are three primary types of acid zinc plating
baths: straight ammonium chloride, straight potassium chloride and
mixed ammonium chloride/potassium chloride. Acid zinc plating
systems have several advantages over alkaline cyanide and alkaline
non-cyanide zinc plating systems except that in acid zinc plating,
the electrolyte is extremely corrosive.
Ammonium chloride zinc plating. The ammonium chloride bath
is the most forgiving of the three major types of acid zinc plating
because of its wide operating parameters.
Potassium chloride zinc plating. Potassium chloride zinc
plating solutions are attractive because they contain no ammonia.
The disadvantages of this system are a greater tendency to burn on
extreme edges and higher operating costs.
Mixed ammonium chloride/potassium chloride zinc plating.
This bath combines the best of the ammonia and ammonia-free baths.
Because potassium chloride is less expensive than ammonium chloride,
the maintenance costs of the mixed bath are lower than the ammonia
bath.
Galvanizing, Soldering and Tinning Fluxes:
Zinc chloride is used in fluxes for galvanizing, soldering and
tinning. Its ability to remove oxides and salts from metal surfaces
insures good metal to metal bonding. It has
the ability to attack metal oxides (MO) to give derivatives of the
formula MZnOCl2.
This reaction is relevant to the utility of Zinc chloride
as a flux
for soldering - it dissolves oxide coatings
exposing the clean metal surface. Typically this flux was prepared
by dissolving zinc foil in dilute hydrochloric acid
until the liquid ceased to evolve hydrogen; for this reason, such
flux was once known as killed spirits or "Marela".
Agriculture: Zinc chloride is very rarely used in
agriculture. It may be reacted with chelating agents to form
solutions of zinc that are biologically available to plants and
animals. It's the Chelate manufacturing that consumes Zinc chloride.
Petroleum:
It is an excellent emulsion
breaker and is used to separate oil from water. It
is also an effective packer fluid in oil and
gas wells due to its high specific gravity. However its a little
more costly than the other low specific gravity fluids used in the
process.
Water Treatment:
It is used in specialty
corrosion inhibitors in cooling towers, potable water, and in gas
and oil wells.
Resins: It is used in
Ion - Exchange
resins production.
Paints:
It is used in for the
production of lithopone and as pigment for zinc chromate.
Rubber: It
is used as accelerator in
the vulcanizing process of rubber.
Glue, wood working:
Zinc chloride is used in for
the preservation of glue, and for the impregnation of timber.
Printing:
It is used in off-set in
the chemical products.
Odor Control:
It reacts with sulfide to minimize release
of H2S gas in waste treatment facilities.
Oil-Gas Wells:
High-density solutions of Zinc Chloride and calcium chloride give good performance in well completion
and work-over operations; the solutions also used as packer fluids
under certain well conditions. ZnCl2 has been used in specialty
corrosion inhibitors and invert emulsion breakers.
Vulcanized Fiber & Reclaimed Rubber: Water-leaf paper is
gelatinized with zinc chloride solution is lesstacky, drier and less
moisture-absorbent than caustic reclaimed rubber.
Animal drug:
It is used for the production of zinc
bacitracin.
Herbicide:
Zinc chloride
is used as
an herbicide. It is used to control lichen and moss growing on the
roofs of houses and other domestic dwellings, along walks,
driveways, fences, and wherever moss grows
Chemical: Zinc Chloride is used in the
production of ethyl acetate. It is used as
condensing agent for the production of organic dye-stuff.
It is used as a stabilizing agent for
diazonium compounds. It is used for the
production of active carbon. Zinc
Chloride is used for Friedel Craft
Reaction, Azotropic or
Azeotropic Distillation, Desiccation
etc.

IT IS NICE TO BE IMPORTANT BUT ….... BUT
IT IS MORE IMPORTANT TO BE NICE
I shall
pass through this world, but once. If therefore, there is any
good that I can do, or if there is any favour that I can show to
a fellow human being, let me do it now. Let me not defer or
neglect it. For I shall not tread this way again.
