Thiourea Dioxide (TDO) is an excellent reducing agent. Compared with insurance powder, this reducing agent has the following advantages:

1. Good stability In alkaline solutions, the stability of thiourea dioxide exceeds that of commonly used reducing agents.

2. Strong reducing ability Thiourea dioxide has a stronger reducing ability than several reducing agents currently in the market.

3. Storage safety powder is a kind of fine wet powder, which can accelerate its decomposition and even burn when exposed to air or moisture, so it needs to be protected from moisture and sealed. my country's requirements for the transportation of insurance powder are second-level water-burning items, and thiourea dioxide is a non-hygroscopic free-flowing powder that does not burn in water. It is a safe chemical and is not in the new version of the 2015 version of the dangerous goods list.

4. The amount of use is small, and the amount of thiourea dioxide used in printing and dyeing is generally only about 20% of the insurance powder, and the reduction of the amount of use not only means lower costs but also can reduce pollution.

5. Non-polluting thiourea dioxide has no mutagenic activity, so it can be considered as a non-carcinogenic substance; on the other hand, it is easily degraded by organisms. The chemical oxygen demand (COD) of pure thiourea dioxide is 0.29g/g, and the biological oxygen demand (BOD) is 0.21g/g. The decomposition products of thiourea dioxide in alkaline solution are urea and sodium sulfate, any of the two None of them will increase COD and BOD, and urea is also beneficial to the treatment of sewage by biochemical methods. Therefore, it can be considered that thiourea dioxide is a non-polluting raw material.
