Company profileBusiness Type : Manufacturer/Factory&Trading Company Main Product : Magnesium Chloride Calcium Chloride,Barium Chloride, Sodium Metabisulphite, Sodium Bicarbonate Number of Employees : 150 Year of Estabulishment : 2006 Management System Certification: ISO 9001 Location : Shandong,China(Mainland)Basic informationProduct Name: SODA ASH Common Chemical Names: Soda Ash, Sodium Carbonate Chemical Family: Alkali CAS Number: 497-19-6 Formula: Na2CO3 Bulk Density: 60 lbs/cubic foot Boiling Point: 854ºC Color: White Crystal Powder Solubility in Water: 17 g/100 g H2O at 25ºC Stability: Stable Physical properties Character Sodium carbonate is a white odorless powder or particle at room temperature.With water absorption, exposed in the air gradually absorb 1mol/L water (about =15%).The hydrates include Na2CO3·H2O, Na2CO3·7H2O and Na2CO3·10H2O. Solubility Sodium carbonate is easily soluble in water and glycerin. Chemical properties The aqueous solution of sodium carbonate is alkaline and corrosive to a certain extent, and can double decompose with acid, but also with some calcium salt, barium salt double decompose reaction.The solution is alkaline and can turn phenolphthalein red. Stability Strong stability, but can also be decomposed at high temperature, to produce sodium oxide and carbon dioxide ; Long-term exposure to the air can absorb moisture and carbon dioxide in the air, generate sodium bicarbonate, and form a hard block. Hydrolysis reaction Because sodium carbonate is hydrolyzed in an aqueous solution, the ionized carbonate ions combine with hydrogen ions in water to form bicarbonate ions, resulting in the reduction of hydrogen ions in the solution, leaving the ionized hydroxide ions, so the pH of the solution is alkaline. Reaction with acid Sodium carbonate reacts with all kinds of acids.Take hydrochloric acid, for example. In sufficient quantities, sodium chloride and carbonic acid are formed, and the unstable carbonic acid is immediately decomposed into carbon dioxide and water. Reaction with alkali Sodium carbonate can double decompose with calcium hydroxide, barium hydroxide and other bases to form precipitate and sodium hydroxide.This reaction is commonly used in industry to prepare caustic soda. Reaction with salt Sodium carbonate can double decompose with calcium salt, barium salt, etc., to generate precipitation and new sodium salt:Product detailsTechnical Specifications

Preparation of Soda AshThere are mainly two kinds of Ammonia Alkaline method and Combined Alkaline method . 1)Ammonia alkaline method It is one of the main methods for industrial production of Soda Ash .It is characterized by cheap ingredients, easy availability and recycling of ammonia (less loss;Suitable for mass production, easy to mechanization and automation).However, the raw material utilization rate of this method is low, especially the NaCl rate.The main production processes include brine preparation, limestone calcination, ammonia brine preparation, carbonation, separation and calcination of heavy alkali, ammonia recovery, etc.The reaction process is as follows: CaCO3 ＝CaO+CO2↑－Q CaO+H2O= Ca(OH)2＋Q NaCl+NH3+H2O+CO2＝NaHCO3 ↓+NH4Cl＋Q NaHCO3 ＝Na2CO3+CO2↑+H2O↑＋Q NH4Cl+ Ca(OH)2 = Ca Cl 2 +NH3 +H2O＋Q 2)Combined Alkaline method With salt, ammonia and carbon dioxide byproducts of synthetic ammonia industry as raw materials, the simultaneous production of soda ash and ammonium chloride, that is, the combined production of soda ash and ammonium chloride, referred to as "combined alkali production" or "combined alkali" main reaction is: NaCl+NH3+H2O+CO2= NaHCO3 ↓+NH4Cl NaHCO3 = Na2CO3+CO2↑+H2O↑ * According to the times of adding raw materials and the different precipitation temperature of ammonium chloride, there are many processes for combined alkali production. Our country mostly uses: one time carbonization, two times ammonia absorption, one salt, low temperature ammonium out process.ApplicationsAsia Africa Australasia Europe Middle East North America Central/South AmericaMain Export Markets1)The glass industry is a large consumption department of soda soda, each ton of glass consumption of 0.2t soda soda. Mainly used in float glass, picture tube glass shell, optical glass, etc. 2) It can also be used in chemical industry, metallurgy and other departments .The use of heavy soda can reduce the dust of alkali, reduce the consumption of raw materials, improve the working conditions, improve the quality of products, reduce the erosion effect of alkali powder on refractory materials, and prolong the service life of kiln. 3)As buffer, neutralizer and dough improver, can be used in cakes and pasta food, according to the production needs of appropriate use. 4) Used as a detergent for wool rinsing, bath salts and medicine, as an alkali in tanning leather. 5) Used in food industry, as a neutralizer, leavening agent, such as the manufacture of amino acids, soy sauce and noodle food such as steamed bread, bread, etc.It can also be prepared into alkaline water and added to pasta to increase elasticity and ductility.Sodium carbonate can also be used to produce monosodium glutamate. 6) Special reagent for color TV 7) Used in pharmaceutical industry as acid antidote and osmotic laxative. 8) Anhydrous sodium carbonate is used for chemical and electrochemical oil removal, electroless copper plating, aluminum etching, aluminum and alloy electropolishing, aluminum chemical oxidation, phosphating after closing, process rust prevention, electrolytic removal of chromium coating and removal of chromium oxide film, also used in pre-copper plating, steel plating, steel plating alloy electrolyte 9) Metallurgical industry for smelting flux, mineral processing with flotation agent, steelmaking and antimony smelting as a desulfurizer. 10) Printing and dyeing industry used as a water softener. 11) It is used in leather industry to degrease raw leather, neutralize chrome tanning leather and improve the alkalinity of chrome tanning liquor. 12) A reference for the calibration of acid in quantitative analysis.Determination of aluminium, sulphur, copper, lead and zinc.Urine and whole blood glucose tests.Analysis of silica cosolvent in cement.Metallic metallographic analysis, etcPackaging General packaging specification: 25KG,50KG;500KG;1000KG Jumbo Bag; Packaging Size : Jumbo bag size: 95 * 95 * 125-110 * 110 * 130； 25kg bag size: 50 * 80-55 * 85 All packing bags are PP outer bag with PE inner bag; The outer bag has coating to protect the quality of the goods; Jumbo Bag with safety factor 5:1 , could meet all kinds of long-distance transportation.
