Sodium hydroxide, with the chemical formula NaOH, commonly known as caustic soda, lye, or 苛性钠, is one of the most fundamental inorganic chemical raw materials. This product is a white, semi-transparent flake solid (flake caustic soda) with a purity of up to 99%. It possesses properties such as strong alkalinity, high corrosivity, deliquescence, and exothermic dissolution in water. As the "mother of chemicals," its applications permeate almost all industrial sectors of the national economy and serve as a key indicator of a country's chemical industry level.
- Soap and Detergent Manufacturing: Sodium hydroxide is the irreplaceable raw material for the saponification reaction, reacting with animal and vegetable fats to produce soap (sodium fatty acid salts) and glycerol, forming the starting point of the synthetic detergent, toilet soap, and laundry powder industry chain.
- Digesting Agent in Paper Industry: In alkaline pulping processes (e.g., kraft process), it is used to digest plant raw materials, dissolve lignin, and separate cellulose, representing the largest consumption segment of caustic soda in the paper industry.
- Scouring and Mercerizing Agent in Textile Dyeing: Used for desizing and scouring cotton fabrics to remove impurities, and for "mercerizing" cotton yarn or fabric, significantly enhancing fiber strength, luster, and dye affinity.
- Synthesis of Basic Chemicals: A key raw material or catalyst for producing numerous organic and inorganic chemicals, including alumina (Bayer process), propylene oxide, pesticides, dyes, and pharmaceutical intermediates.
- Petroleum Refining: Used for "caustic washing" of crude oil to remove acidic impurities like hydrogen sulfide and mercaptans, refining oil products.
- Biodiesel Production: Acts as the catalyst in the transesterification reaction, converting oils and fats into fatty acid methyl esters (biodiesel).
- Wastewater Treatment: Widely used for neutralizing acidic wastewater, adjusting pH to levels suitable for biological treatment; also used for chemical phosphorus removal, heavy metal precipitation, and sludge conditioning.
- Water Treatment: Used to adjust the pH of industrial process water and cooling tower circulating water to prevent equipment corrosion and scaling.
- Flue Gas Desulfurization: Used in some wet scrubbing processes to absorb sulfur dioxide.
- Food Processing (Food Grade): Strictly complies with standards like GB 1886.20, used as a processing aid for cleaning, peeling (e.g., lye peeling of fruits), cocoa processing, and vegetable oil refining.
- Aluminum Smelting: The core reagent for processing bauxite to produce alumina.
- Lithium Batteries: Used for pH adjustment and impurity removal in the synthesis of cathode material precursors (e.g., NMC materials) and in battery recycling processes.
Our supplied flake caustic soda features high purity, low impurity content (especially iron and sodium salts), uniform flakes, and rapid dissolution. It is packaged in moisture-proof, sealed bags (e.g., 25kg PE-lined woven bags) to effectively prevent deliquescence and caking.
We provide stable, high-quality flake caustic soda to soap factories, paper mills, chemical plants, wastewater treatment plants, and food processing enterprises, accompanied by safety usage training and technical solutions to ensure our clients can efficiently and safely utilize this fundamental yet powerful chemical.
