English Name: 2,5-Dimercapto-1,3,4-thiadiazole, dipotassium salt

CAS NO: 4628-94-8

Molecular formula: C2N2S3 1, product performance

Metal antioxidant DT2K is composed of dimercapto-1,3,4-thiadiazole, potassium hydroxide and some additives. It is mainly used as water-soluble metal antioxidant and metal corrosion inhibitor, especially suitable for corrosion inhibition of copper or copper alloys. The product can form a compact protective film on the metal surface. The film has a considerable thickness, which can effectively isolate various external corrosion factors and play the role of corrosion inhibition and oxidation resistance. Metal antioxidant DT2K is an important corrosion inhibitor and heavy metal scavenger for water treatment agent. It is also the raw material of vulcanization accelerator TMT. The cost of water-soluble metal antioxidant DT2K is lower than that of BTA. It has great market application value. In addition, it can also be used as plasticizer and acidic copper plating tometer.

3. Scope and method of use

Metal corrosion inhibitor DMNA can be used as copper corrosion inhibitor in circulating cooling water system. The inhibition of DMNA mainly depends on the chemical adsorption of active copper atoms or copper ions on the surface of metallic copper, or the chelation of DMNA to form a dense and firm protection.

This product is widely used as corrosion inhibitor for copper in cooling chemical treatment. It can be used as corrosion inhibitor in power plants, chemical plants, oil refineries, oil fields and other systems with copper as the material of equipment. In addition, it can also be used as corrosion inhibitor in rust-proof liquid and metal processing. Usage is generally 2-6 mg/L, which can be directly or diluted with water and put into the system.

4. Packaging and Storage

The product contains 50% liquid and is packed in plastic barrels, 25kg/barrel 250KG/barrel, and 98% powder in cardboard barrels of 25kg/barrel. It is stored in a cool and dry place for 10 months, avoiding mixing with acidic materials.

5. Safety and Protection

This product has the possibility of alkaing. It should be equipped with protective glasses and rubber gloves. Once it touches the skin and eyes, it should be washed with plenty of water immediately and be treated in time.
