Product Introduction: Light soda ash is a basic inorganic chemical raw material, refined by ammonia-alkali method and combined alkali method. It features high purity and high reaction activity, widely used in industrial production, daily chemical industry, water treatment, printing and dyeing and other industries.
2. Physical and Chemical Properties
It is an odorless white powder with astringent taste. It is easily soluble in water with fast dissolution speed, and its aqueous solution is strongly alkaline. Slightly soluble in anhydrous ethanol, insoluble in acetone. It has excellent chemical reaction activity and stable chemical properties with uniform batch quality. With slight hygroscopicity, it can be decomposed at high temperature, serving as a highly versatile industrial soda ash raw material.
3. Product Technical Indexes


Index Description: The product is divided into three specifications: industrial superior grade, industrial first grade, and food grade, complying with corresponding national standards. Industrial grade focuses on purity and production stability, suitable for daily chemicals, water treatment, printing and dyeing, metallurgy, and other general industrial production. On the basis of industrial grade, food grade strictly controls toxic and harmful impurities such as heavy metals, arsenic, and lead with higher safety. It can be legally used for dough leavening, food processing neutralization, food additive preparation, and other food contact scenarios, fully complying with national mandatory standards for food additives, with complete test reports and compliance qualifications available.
Index Description: Industrial superior grade has lower impurities and higher purity, applicable to high-precision production scenarios such as fine chemical industry and high-end daily chemicals. Industrial first grade has higher cost performance, suitable for general industrial scenarios including conventional water treatment, printing and dyeing papermaking, and basic metallurgical desulfurization.
4. Product Characteristics
Light soda ash is fine white powder with loose and light texture, featuring fast dissolution speed and high chemical reaction activity. It has high purity and extremely low impurities with excellent cost performance and wide application range. Slightly hygroscopic, it remains stable without deterioration or failure under conventional storage conditions, though the fine powder is easy to fly.
5. Main Applications
The products are divided into industrial grade (superior grade & first grade) and food grade with dedicated and classified application scenarios as detailed below:
5.1 Applications of Industrial Grade Light Soda Ash
Industrial grade light soda ash meets industrial production impurity standards with high cost performance and strong reaction activity. It is a core basic alkaline raw material for light industry, environmental protection, chemical industry, metallurgy and other fields. Specific applications are as follows:
·
Daily Chemical & Detergent Industry: As the core raw material for washing powder, laundry detergent, soap, toilet soap, dish soap and other cleaning products, it softens water, removes oil stains, neutralizes acidic stains, improves detergency, and stabilizes the pH value of detergent products.
Printing, Dyeing & Papermaking Industry: Used as a neutralizer, color fixing auxiliary, and water softener in printing and dyeing production to adjust the pH value of dye liquor and improve the color uniformity and fastness of fabrics. In papermaking, it is applied for pulping alkalization, pulp degumming, and wastewater pH adjustment to optimize paper forming quality.
Environmental Protection & Water Treatment Industry: Widely used for acid-base neutralization of industrial and domestic sewage to neutralize acidic wastewater and adjust water pH value. It is also adopted in flue gas desulfurization and denitrification to adsorb and neutralize sulfides and acidic harmful gases in exhaust gas, meeting environmental protection discharge standards.
·
·
Chemical Synthesis Industry: Used for the production of phosphate, silicate, sulfate, baking soda, and other inorganic salt chemical products. It serves as a basic alkali source for chemical reactions with sufficient raw material reaction and high conversion rate, adapting to various fine chemical and basic chemical synthesis production lines.
Metallurgical Desulfurization Industry: Applied in desulfurization and dephosphorization processes for steel and non-ferrous metal smelting to remove impurities from metal raw materials, optimize smelting quality and reduce pollution from smelting waste gas and residue.
Other Industrial Fields: Available for leather degreasing, oilfield drilling auxiliaries, ceramic blank pretreatment, rubber auxiliary preparation and other industrial scenarios, covering all basic industrial alkalization demands.
5.2 Applications of Food Grade Light Soda Ash
Food grade light soda ash strictly complies with national food additive standards, with strictly controlled harmful impurities such as heavy metals, arsenic and lead. It is non-toxic, food-contact safe and exclusively used in food processing industries, prohibited for industrial use. Specific applications are as follows:
Pastry Processing: Special edible alkali for steamed buns, buns, noodles, wonton skins, cold noodles, pastries and other pasta products. It neutralizes lactic acid produced by dough fermentation, removes sour taste, brightens pasta color, and makes pasta soft, chewy and better in appearance and taste.
Food pH Adjustment: Used for pH value adjustment and acid neutralization in various food processing processes, suitable for bean products, rice and noodle products, pastry baking, and other food processes to optimize food flavor and stabilize the food production system.
Food Cleaning & Decontamination: Used for soaking and cleaning fruits, vegetables, grains, and dry food materials to remove residual pesticides, acidic impurities, and oil stains on the surface of food materials with no safety residue, serving as a special cleaning auxiliary for food processing workshops.
Food Additive Synthesis: As a basic raw material for food additives, it is used in the preparation and production of food leavening agents, edible buffers and food improvers, compliant with food deep processing industry standards.
Aquatic & Meat Product Processing: Appropriately used for soaking and tenderizing aquatic products and meat products to improve the texture and appearance of food materials, meeting food processing safety standards.
