Factory was located in the border area of northwest China - Xinjiang, the foot of the beautiful TianShan Mountain. Now has more than 22 million RMB in fixed assets, cover an area of 47,000 square meters and currently employs 62 people, with an annual production capacity of semi-coke 100 thousand tons and chemical products 80 thousand tons,including 20,000 tons Sodium Sulphide, 12,000 tons Sodium Hydrosulfide, 30,000 tons Caustic Soda and 18,000 tons other chemical products.
The predecessor of Tiandeli was Tianjin Office, with the development and accumulation of business, founded Tiandeli Co.,Ltd in Tianjin to serve customer better. In recent years, Company's business is more diversified, was composed of exporting, domestic, agent and importing. In addition to the supply in the domestic market and Xinjiang, our products exported to Southeast Asia, the Middle East, Central Asia, India, Pakistan, Bangladesh, Africa, South America and other countries and regions. The main quality products are: semi-coke, sodium sulphide, sodium hydrosulfide, caustic soda, sodium metabisulphite, sodium thiosulfate , sodium bicarbonate, sodium formate, pre-cipitated barium sulfate, SLES, Dextrose Monohydrate and Dextrose Anhydrous.
Through every employee unremitting efforts and the trust from domestic and foreign customers, Tiandeli established a good reputation in the process of business development and cooperation. While actively explore the international market, Tiandeli has become the exporting agent of service chemical enterprise. And has established long-term stable relations of cooperation with a number of well-known domestic chemical enterprises.
Since Tiandeli was founded, we have been committed to advance growth through providing detailed and thoughtful service to our customers. We constantly improve management concept and management mode, hope to obtain partners at home and abroad more widespread support through our own unremitting efforts.
Our company adhere to the management policy “develop the International market, optimize the structure of the products, technical research and development, standard management” opening up the market outside, grasp the management inside. Adhere to the service concept of “Strive! Satisfy you!”
Chemical name: Sodium Sulphide Na2S.
Product NO.: 28301010
CAS NO. : 1313-82-2
Molecular Ormula: Na2S
Molecular Weight: 78.04
Used as reducing agent or mordant agent in making sulphur dyes, as flotation agent in non-ferrous metallurgical industry, as mordant agent for cotton dying, used In tanner industry, in pharmacy industry making some phenacetin, in electroplate industry, for hydriding galvanize.
Nature: yellow or red flakes, strong moisture absorption, soluble in water, and water solution is strongly alkaline reaction. Sodium sulphide will cause burns when is touched with the skin and hair. The method of solution in the air will slowly oxygen.
Sodium thiosulfate, sodium sulfite, sodium sulphide and sodium polysulfide, because sodium thiosulfate’s generating speed is faster, its major product is sodium thiosulfate. Sodium sulphide is deliquesced in the air and carbonated so that it is metamorphic, and constantly release hydrogen sulfide gas. The industrial sodium sulphide includes impurities, so its color is red. Specific gravity and boiling point are influenced by impurities.
Function and Usage: sodium sulphide is used to produce vulcanization dye, sulphur cyan, sulphur blue, dye intermediates reductance, and other nonferrous metallurgy industry used for ore flotation agents. Sodium sulphide can also make the depilatory cream in the leather industry. It is cooking agent in the paper industry. Meanwhile, sodium sulphide is also used to produce Sodium thiosulfate, sodium sulfite and sodium polysulfide.
