Soda Ash Is Used As A Bleaching Agent In The Textile Industry For Neutralizing Acidic Effects And Raise Ph Levels
Soda Ash |
Soda Ash, commonly known
as sodium carbonate or calcined soda, is an odorless white powder and has many
uses across a wide variety of industrial applications. This granular chemical
compound is used in manufacturing glass, paper, detergents and chemicals
amongst other industrial products. It is also an essential ingredient in everyday
lives and has a number of domestic applications including water softening and
as an acidity regulator.
Soda Ash is created through a chemical
reaction of calcium chloride with sodium hydroxide. This process is performed
under standard conditions for temperature and pressure. This reaction produces
the anhydrous form of the compound with a density of 2.54 grams per cubic
centimetre. The anhydrous form of the compound is hygroscopic and has a melting
point of 851 degrees Celsius.
Depending on the manufacturing process, soda
ash can be classified as “natural” or “synthetic”. Natural soda ash is made
from the mineral trona and is sourced from the Green River Basin in Wyoming.
Synthetic soda ash is manufactured through a series of chemical reactions from
limestone and salt and has a higher energy consumption than the natural form.
More than half of all soda ash produced is
used in glass manufacturing, with the remainder going towards detergents and
other chemical processes.
Soda Ash is often used as
a bleaching agent in the textile industry, where it works to neutralize acidic
effects and raise pH levels. It is also a key ingredient in dyeing with fiber-reactive
dyes, where it acts as a mordant to help the color bond with the cellulose fibers.
It can be applied before the dyeing, mixed with the dye or after the dyeing to
increase the intensity of the finished product.
Soda ash is often used as a concrete
accelerator, as it speeds up the set time of concrete, allowing it to be poured
sooner and at a lower temperature. It is also a common pool additive to
maintain a balanced alkaline level in the water.
Soda ash is commonly used to clear drains and
as an abrasive in cleaning products. For the former, simply pouring a quarter
cup down the drain can be enough to keep them unclogged for a few weeks.
Soda Ash can be found in toothpaste
and baking powder; the former as a leavening agent and the latter as an
abrasive to help with the removal of teeth plaque. It can also be used in water
softening by neutralizing acidic effects and reducing the concentration of
calcium and magnesium ions in the water, which prevents the buildup of scale on
pipes and appliances.
The Turkish
glassmaker Sisecam, declared the acquisition of 60% of Ciner's soda business in
the United States in December 2021.
