THAW
Salt (sodium chloride) is one of the products most used for removing snow and ice from the ground. It acts as a flux melting snow and ice, lowering the freezing temperature of water, prevents the formation of ice, up to about -15°.

The particle size is important because the fine salt allows a faster but less durable dissolution while the coarse salt causes the opposite effect. So a proper mixture of various grain sizes is the most efficient and economical solution to protect the road conditions even in the coolest months.

CIS produces sea salt for thawing: a wet salt that contains anti-caking. (Medium-large granulometric cuts for optimum efficiency).
It’s available in our facility in Porto Viro (RO), in 25 kg bags, or directly in bulk for direct loading, and can also be delivered at the place of destination.

CHEMICAL INDUSTRY
CHEMICAL INDUSTRY
Three main areas of chemistry are users of salt: the electrolysis of sodium chloride, the production of sodium carbonate and the production of sodium sulfate.

The electrolysis of sodium chloride allows to obtain chlorine, sodium hydroxide, and under certain conditions also sodium chlorate and sodium metal.
The chlorine is mainly used for the production of raw plastics materials such as polyvinyl chloride (PVC) but also to produce chlorinated solvents and bleaching products and disinfectants, such as bleach.
The sodium hydroxide (or caustic soda) is a chemical intermediate used for the production of regenerated textile fibers, paper pulp, aluminum oxide.
The sodium chlorate is used as a herbicide, as a bleaching agent and also enters in the manufacture of some explosives.
The sodium metal has instead important outlets in organic chemistry as an agent of synthesis, and nuclear industry as a fluid to transport heat.

Calcium carbonate is used as a reagent in the chemical industry, mainly in the glass industry. Its production puts into action the two raw materials: sodium chloride and sodium carbonate with an intermediary: ammonia.

Sodium sulfate is used in paper industry, glass industry and in detergents, and as an agent for the manufacture of other chemicals. This product is obtained in the ovens where the crystallized sodium chloride is mixed up with sulphurous acid at a temperature of +550°C.
TEXTILE INDUSTRY
TEXTILE INDUSTRY
Salt used in the preservation of hides and leather hides from slaughter must be stored for long periods without developing bacteria susceptible to damage them. The process most widely used consists in dehydrating the skin with sodium chloride. Salt should be used in well defined conditions with particle size and precise chemical composition.

In textiles, salt is used both for the production and for fixing different types of dyes.

The dyeing with reactive dyes is divided into three phases: climb of the dye on the fiber by factors such as temperature and addition of electrolyte, fixation of the dye by addition of alkali type sodium carbonate or caustic soda, elimination of the unreacted dye.

Direct dyes are a class of colorants consisting of sodium salts of sulphonic acids that are applied in neutral solutions. They are called direct because they dye directly the cellulose fiber without the use of “mordant”. To shift the equilibrium of the dye from the bath to the substrate, electrolytes are used such as sodium chloride or sodium sulfate.
METALLURGY
METALLURGY
Carburizing and hardening of metals: sodium chloride is associated with other minerals to obtain salt baths with a melting temperature precise. These baths are used for the process of carburizing (heating at an elevated temperature) and quenching (rapid cooling) to give greater resistance to the metal surface.

Refining of aluminum: the waste from aluminum smelters contains mainly oxides and aluminum alloys. These waste is used for the production of secondary fusion aluminum with refining to about 800°C by mixing the waste with the salt or another alkali chloride whose role is to restrain the sterile material.

Electroplating: is an electrochemical process that allows, through the electrolysis, to cover a thin layer of noble metal (gold, silver, copper, chromium, zinc ...) with another metal. The acid bath that allows it is a mixture of noble metal and the chloride of hyperpure salt that covers the role of electrolyte.
