Brief Overview

 

Industrial salt, also known as sodium chloride has a chemical formula NaCl. It is an ionic salt and exists as the white crystalline solid. It is readily soluble in water and slightly soluble in most other liquids and insoluble in concentrated hydrochloric acid. Industrial salt contains no traces of any impurity whereas common salt contains impurities that are desirable in our daily life. The thermal conductivity of sodium chloride decreases with increasing temperature and also decreases with doping. Sodium cations are metallic conductors and when temperature increases, the thermal populations of higher energy levels in the molecular orbits are expected to bring about an increase in conductivity. However, thermal vibrations of the nuclei produce electrical resistance and this effect is sufficiently enhanced at a higher temperature, resulting in a decrease in conductivity of the metal at a higher temperature.



Manufacturing Process

 

Sodium chloride exists in abundance naturally as mineral, halite. They can be mined by pumping water into mines to dissolve the rock salt. The water is then allowed to evaporate such that NaCl re-crystallized and collected for further processing and purification for industrial consumption.

Sodium chloride can also be collected by evaporating brine from underground salt deposits and seawater. Saturated brine is then passed through a series of re-crystallization ponds where sodium chloride salt will crystallize out. The crystals are isolated, further purified using crystallization, processed and standardized for industrial consumption.



Textile Industry

 

Industrial salt is used for rinsing in textile processing to separate organic contaminants and help with salt out of dyestuffs precipitate. Dyes are generally negatively charged and they get absorbed to the positively charged sodium cations readily. They will form   insoluble compounds and eventually precipitate out, allowing easy removal and isolation. It is also used to blend with concentrated dyes to standardize them.
