Sodium thiosulfate is a commonly used chemical material, as the fixing agent in photography, film and printing plate-making industry, as a reducing agent used in tanning. It is used as a bleaching agent for removing residual and a mordant in the paper and textile industries, as antidotes of cyanide poisoning in medicine, as dechlorination agent and fungicides of drinking water and wastewater in water treatment, as a copper corrosion inhibitor of circulating cooling water and a deoxidizer of boiler water systems. It is also used for Cyanide wastewater treatment. Soda ash and sulfur are generally used as raw materials in industry, soda ash reacts with sulfur dioxide produced by the combustion of sulfur to produce sodium sulfite, then add sulfur for boiling reactions, and then filter, bleach, concentrate and crystallize, etc, can obtain sodium thiosulfate pentahydrate. Other production waste containing sodium sulfide, sodium sulfite, sulfur and sodium hydroxide can also be used, after appropriate treatment to get the product.

Function:

1.Sodium thiosulfate is Used in manufacture of the fixing powder and preparation of the photographic industry fixer, desiccant. Used as a reducing agent of dichromate in leather tanning industry.

2.Sodium thiosulfate is an important inorganic chemical raw material. It can be used in the synthesis of pesticides Bisultap, Thiosultap disodium, CARTAP and so on.

3.Used as analytical reagents, mordant and fixer.

4.Used as new insecticides, with stomach poisoning, uptake and contact action effects, it can prevent and treat rice yellow stem borer, stem borer, leaf roller, rice thrips and vegetables, fruit pests.

5.With uptake and strong contact, stomach poisoning effects, it can prevent and treat various rice pests and vegetables, fruit pests.

6.Used as the chlorine removal agent for Pulp and cotton fabric bleached, as chelating agents, anti-oxidants in the food industry, as detergents, disinfectants in the pharmaceutical industry.

7.Used as chelating agents, antioxidants, anti-browning agent, as the dechlorination agent of chlortetracycline hydrochloride (or chlortetracycline) chilled with ice, dechlorination reaction is as follows:More chlorine content will cause side reactions of free sulfur, so only used for very dilute concentrations of chlorine.

Application:

1. One of the disinfectants used as cyanide.

2. Allergy

3. Treatment of blood pressure drug sodium nitrate overdose intoxication.

4. Treatment of soluble barium salts (e.g. barium nitrate) poisoning

5. Treatment of arsenic, mercury, bismuth, lead and other metal poisoning

Specification :

All Key Manufacturers and Suppliers of Baoji Guokang have routine inspections to ensure they are in compliance with the standards set in place during the original Supplier Assessment Inspection.

Production Inspection Process:

Our Group service includes regular and thorough inspections throughout the manufacturing process, eliminating the need to employ additional quality control inspectors.
