Use of the Zinc Chloride are Following :

Fluxes :

The property to attack metal oxide and salts from metal surface and gives good metal to metal bonding make Zinc Chloride a better raw material for fluxes.

________________________________

Dry Cell Batteries :

Zinc Chloride is used in Dry Cell Batteries as an electrolyte and also as a moisture absorbent and corrosion inhibitor.

________________________________

Glue :

It is used in manufacture of Glue, Paper, Cosmetics, Synthetic, Fibers, Disinfectants and Fire Fitting form.

________________________________

Electro Plating :

It is one of the main raw material for manufacturing of electroplating chemicals.

________________________________

Wood Preservative :

It is also a good preservative.

________________________________

Water treatment Chemicals :

It is using in water treatment because of corrosion inhibitor property.

________________________________

Catalysts :

Zinc Chloride is used as a catalyst in production of methylene chloride from methyl alcohol.

________________________________

Petroleum :

It is used to separate water from oil as it is a good emulsion breaker. It is also used in oil and gas wells.

________________________________

Rubber Vulcanization :

It is used as accelerator in the vulcanizing process of rubber.

________________________________

Anteseptic AND Deodorant Preparation :

Zinc Chloride is also used to prepare antiseptics and deodorants.

________________________________

Textile Finishing :

Zinc chloride is a more active catalyst than magnesium chloride and almost as active as zinc nitrate. It does not contribute to resin yellowing on white goods and has little effect on dye shades in tinted materials. The textile grade is used as a catalyst in resin systems that impart a durable-press or wash and wear finish to cotton and cotton synthetic blend fabrics. Zinc Chloride 50% Solution also serves as a high quality mercerizing agent for cotton.

________________________________

Raw Material & Other Chemicals :

Zinc Chloride is an excellent source of zinc and used as a raw material for the production of other zinc chemicals.

Carbohydrazide is used as an oxygen scavenger for high pressure boilers in power plants and other industries to reduce corrosion of metal pipes and fittings.

What is CarboHydrazide ?
Carbohydrazide the hydrazide of carbonic acid.

Why use Heat Transfer molten salts?

Heat Transfer Salt extend the upper range of the temperature limits in which a liquid heat transfer media can be used.

Efficiency :Rapid Softening, disintegration and dissolving of scales.

Economy

By reducing down-time, productivity is increased. by protecting metal and by uniform leaning of the surface equipment life is prolonged and performance made superior. The above information is adequate for commonly encountered problems of descaling.

Handling & Storage

Safety

•    No Fumes Avoid contact with skin or eyes. Wear Cup-type, rubber or soft plastic-framed goggles, protective clothing, and rubber gloves must be worn when handling.

•    Keep in a tightly closed container. Protect from physical damage.

•    Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities.

•    Containers containing this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.

•    Ensure as low exposure as possible. Local exhaust ventilation is generally preferred as it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.

-   Prevent run off water from entering drains if possible

Formation of Calcium Sulfate is main cause for SCALE formation :::

The principal problem potential posed by sulfate ions in water is the possibility of calcium sulfate scale formation.  Precipitation of calcium sulfate can occur when high concentrations of both calcium and sulfate exist simultaneously.  There are three primary areas of water treatment in which calcium sulfate precipitation may occur boilers, cooling systems, and ion exchangers operating in the hydrogen or acid mode.

In boilers, calcium sulfate scale formation has been reduced to a minimum by modern treatment practices.  The low hardness levels largely preclude calcium sulfate boiler scale.    By contrast, cooling systems are subject to calcium sulfate scale deposition because the makeup is usually not treated for hardness removal.  Cooling water is usually treated with sulfuric acid for pH control, and the makeup is cycled, i.e. concentrated.  Calcium sulfate scale deposition can  result unless the cycles of concentration are properly controlled in conjunction with the proper use of scale control chemicals.  Cation ion exchangers regenerated with sulfuric acid also can pose a major calcium sulfate problem. Calcium sulfate precipitation can be avoided by controlling the acid concentration and the flow rate through the exchanger.
