IRAN CUASTIC SODA FLAKES

IRAN caustic soda flakes (Sodium hydroxide)

Sodium hydroxide (caustic soda), solid is a white and solid (flakes). Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with formula Noah. It is a white solid ionic compound consisting of sodium. Sodium hydroxide is a highly caustic base and alkali,that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. Use in many industries like chemical manufacturing, petroleum refining, cleaning compounds, drain cleaners. White or nearly white pellets, flakes, sticks, fused masses or other forms. Solutions are clear or slightly turbid, colorless or slightly coloured, strongly caustic and hygroscopic and when exposed to the air they absorb carbon dioxide, forming sodium carbonate. Sodium hydroxide is formed from sodium sulphate by a three step operation comprising converting the sodium sulphate to sodium sulphide, converting the sodium sulphide to sodium bicarbonate, and converting the sodium bicarbonate to sodium hydroxide. The operations preferably are effected in conjunction with a bleached kraft pulp mill operation, so as to utilize by-product sodium sulphate from chlorine dioxide generation to produce useful sodium hydroxide as sulphur without co-producing chlorine.

 

There are tree type of custic soda :

  • Caustic soda flakes
  • Caustic soda pearl
  • Caustic soda liquid
  • cuatic soda food grade

 

All about caustic soda flakes

Sodium hydroxide (caustic soda flakes) is a highly caustic substance that is used to neutralize acids and make sodium salts. Sodium hydroxide physically is a white crystalline like snow, odorless and solid that absorbs moisture from the air. It is easily soluble in water when dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide (caustic soda) is very corrosive. It is generally used as a solid or a 50% solution. Other common names include caustic soda flakes and lye. More than 95% production capacity of chlorine and approximately 100% of the production capacity of cadmium (sodium hydroxide) is based on the hydrolysis of salt water. In this process, a solution of sodium chloride (salt water) is decomposed electrically to elemental chlorine and a solution of sodium hydroxide and elemental hydrogen.a liquid production method using sodium chloride as a raw material is a multiprocessing process today, there are generally three commonly used methods to produce caustic soda flakes:

 

membrane method

aperture method

 •Mercury (mercury)

All about caustic soda liquid

There are two type of liquid sodium hydroxid or liquid caustic soda with diffrent precentage of purity 50% and 32%.

caustic soda produce by Alkaline salt and it is the best liquid for Oil, Textile, Paper, Chemical etc.

liquid caustic soda can ship by tank or can pack in steel drum .

storage of caustic soda : it should keep in dry stock which tempreture is between 15 - 55 c .in warm weather more than 55 c it may damage its package and below 15 c liquid will be congealed .

All about food grade caustic soda

The caustic soda often referred to as the sodium hydroxide which without the impurities of iron and mercury that is very suitable for the food industry. Food grade of caustic soda or sodium hydroxide has a wide range of usage in food industry same as refining edible oils, sugar and sugar production, milk and dairy industries, canning, beverage and chocolate production, caramel and cocoa. Olive processing and degradation also help with caustic soda,in baking some special bread , Sodium Hydroxide (Caustic Soda) are odorless, white, solid flaks or. They also are deliquescent. They are used for pH and alkalinity adjustment, and lye peeling of vegetables and fruits. It is a pharmaceutical reactant, catalyst and processing aid, as well as a softener for the epidermis and hydrolyzing fats in soaps. Lye or food grade caustic soda is commonly an another name of sodium hydroxide (NaOH) or historically potassium hydroxide (KOH).

 

Uses of cuastic soda/ sodium hydroxide

There are wide range use of caustic soda flakes in many industries.

  • Adhesives and sealant chemicals
  • Adsorbents and absorbents
  • Agricultural chemicals (non-pesticidal)
  • Anti-adhesive agents
  • Bleaching agents
  • Cbi
  • Corrosion inhibitors and anti-scaling agents
  • Dyes
  • Finishing agents
  • Fuels and fuel additives
  • Functional fluids (closed systems)
  • Intermediates
  • Ion exchange agents
  • Laboratory chemicals
  • Oxidizing/reducing agents
  • Paint additives and coating additives not described by other categories
  • Plasticizers
  • Plating agents and surface treating agents
  • Process regulators
  • Processing aids, not otherwise listed
  • Processing aids, specific to petroleum production
  • Solids separation agents
  • Solvents (for cleaning or degreasing)
  • Surface ac

 

Packing of cuastic soda and sodium hydroxide

There are different kind of packing for industial caustic soda , since caustic soda /sodium hydroxide is chemical product and its imco  better to pack in pp bag which is laminated and don’t allow any water to moisture enter the bag , also for transportation and reducing labor charges we can put bags in 1 MT jumbo bag or 1 MT pallets are possible , in case pallet use as packing certificate of fumigation will arrange for pallets .

Food grade caustic soda and sodium hydroxide ship in safe metal container which keep away caustic soda from moisture and humid condition , Hydroxide is hydrophilic which means that it not only attracts moisture and water but it actively absorbs any moisture or water to which it is exposed.

 

Guaranty/warranty of sodium hydroxide

ATDM guaranty the quality of caustic soda with arrangement of international inspector to check quality and quantity of sodium hydroxid during the loading to vessel and controlling the production by qc by batch test report before shipping. Atdm guaranty the quality to meet with astm.
