Product Description

Product Description

Sodium hydroxide solution is an inorganic compound with the chemical formula NaOH and a relative molecular weight of 39.9970.

It is an important basic chemical raw material and has a wide range of uses. The chemical industry is used to manufacture formic acid, oxalic acid, borax, phenol, sodium cyanide and soap, synthetic fatty acids, synthetic detergents, etc. In the textile printing and dyeing industry, it is used as a cotton desizing agent, scouring agent, mercerizing agent and solvent for vat dyes and Haichang blue dye. Used in the smelting industry to manufacture aluminum hydroxide, alumina and metal surface treatment agents. In the instrument industry, it is used as acid neutralizer, decolorizing agent, and deodorant. In the adhesive industry, it is used as starch gelatinizer and neutralizing agent. In addition, it is widely used in enamel, medicine, cosmetics, tanning, coatings, pesticides, glass and other industries.

A. Refined petroleum
After being washed with sulfuric acid, petroleum products still contain some acidic substances that must be washed with sodium hydroxide solution and then washed with water to obtain refined products.

B. Printing and dyeing

C. Textile fiber

D. Papermaking

E. Use lime to improve the soil.

F. Chemical industry and chemical reagents:
1. Pharmaceuticals
Stomach medicine: The ingredients are aluminum hydroxide, magnesium hydroxide, sodium bicarbonate and a small amount of sodium hydroxide. Its main function is to neutralize gastric acid.
Sodium carboxymethylcellulose (CMC): emulsification, adhesion, and film formation of food and drugs. Used as an anti-soil redeposition agent in detergents. Alkaline cellulose is made by reacting refined cotton with NaOH, and then reacted with chloroacetic acid in a one-step etherification reaction.
2. Green water purification agent
Preparation of sodium ferrate (Na2FeO4)
3NaClO(sodium hypochlorite)+2Fe(OH)3(iron hydroxide)+4NaOH==2Na2FeO4+3NaCl+5H2O
Basic aluminum chloride (PAC/BAC) denatures the protein of the virus. It is used for water purification and wastewater treatment, and strong sodium oxide adjusts the ph value.
3. Ion exchange resin
After anion exchange resin fails, it is generally regenerated with 5%-8% NaOH solution.
4. Alkaline cleaning agent
NaOH solution can be used in the preparation of various cleaning agents, such as car washing liquid, bottle washing liquid, dishwashing liquid, rust remover, and disinfectant liquid. It is mainly used for cleaning bottles in the wine industry, surface treatment in the ceramic metal industry, etc.
5. Sodium hypochlorite bleach

G. Rubber and leather
1. Precipitated silica
2. Recycling of old rubber
In the recycling of old rubber, sodium hydroxide solution is used to pretreat rubber powder and then undergo subsequent processing.
3. Leather

H. Metallurgy, electroplating

I. Other functions
1. The role of ceramic caustic soda in ceramic manufacturing has two points. First, during the firing process of ceramics, caustic soda serves as a diluent. Second, the surface of the fired ceramics will be scratched or rough, so use caustic soda solution to clean it. Finally, the ceramic surface is smoother.
2. Used as acid neutralizer, decolorizing agent, and deodorant in the instrument industry.


Qingdao Fangjinlong Technology Development Co., Ltd. was founded in 2010 and is located in Qingdao City, Shandong Province,
on the coast of the beautiful Bohai Bay. Focus on chemical production and sales for more than 20 years; We have all kinds of dangerous goods licenses; Rich experience in safe transportation; Provide high-quality customer service; and Deliver high-quality products and services to all parts of the world anytime, anywhere.
The company invested in and participated in the operation of two production enterprises in 2006, mainly producing chemical products related to water environmental engineering, including Sodium Hypochlorite, Ferric Chloride, sodium acetate, Polyferric Sulfate,
Polyaluminum Chloride, etc. In 2008, in the laboratory independently operated by the company, famous researchers from the
School of Environmental Science and Engineering, Ocean University of China jointly conducted research and development on sewage treatment chemicals and sludge reduction technology and made breakthrough progress. Obtained three national patents in one fell swoop. In the same year, it was awarded the title of high-quality supplier of large water group companies such as Qingdao Water Group, and Everbright Water Group.
In May 2013, the company invested in the establishment of Qingdao Fangjinlong Supply Chain Co., Ltd., an enterprise in China
(Shandong) Qingdao Free Trade Pilot Zone, which greatly promoted the development of international business. The expansion of
main products involves mining chemical products, petrochemical products, sewage treatment chemical products, food additives, etc.
In order to facilitate the transportation of goods, the company cooperates with well-known freight companies in Huangdao District, Qingdao, and can independently complete the storage and transshipment business of the warehouse, which greatly improves the convenience and safety of goods transportation. Up to now, the company has reached long-term and stable cooperative relations
with 36 companies from South America, North America, Europe, the Middle East, Russia, and other countries and regions. In 2022, the export volume exceeded 80 million US dollars, accounting for 30% of the company's total revenue.
