Specification :

Thiourea dioxide
1. Product Name
Thiourea dioxide, also known as sub-acid amitraz

II. Molecular formula
CH4N2SO2 molecular weight: 108.12

III. The appearance and performance
1. Melting point: 126 ¡æ PH value: the risk of grade 4: 4.2
2. Thiourea dioxide is a no no to restore the oxidative stability of compounds, appearance is white or light yellow crystalline particles, non-irritating odor, solubility in water of 26.7 g / L (20 ¡æ), saturated aqueous solution PH value of 5.0. 20-30 ¡æ, even in the aqueous solution is also very stable, but the role of the heating or alkali, the decomposition will occur, a strong reduction of free sub-acid, it can be controlled with a reduction.
3. Thiourea dioxide with a higher reduction potential, effective, and the reduction potential of the slow rate of decline, only sodium-reduction potential to reduce the number of 1 / 5; In addition, it has good thermal stability, storage transport convenience , non-toxic tasteless, easy to operate, easy storage and transportation. Thiourea dioxide powder is a new type of insurance, environmental protection alternative.
4. Thiourea dioxide good safety performance, production and use of environmentally friendly non-polluting.

IV. Packing
Packaging in accordance with international shipping rules and customer requirements into product packaging:
1. 25kgs kraft paper compound plastic woven bag;
2. 25kgs, 50kgs plastic woven bag;
3. 50kgs cardboard drum;

Products are exported to the United States, Japan, South Korea, and Europe more than a dozen countries and regions.

5. Use
Thiourea dioxide powder is replaced by a new type of insurance products, can be used as reducing agent, bleaching bleaching, plastic stabilizer, antioxidant and organic synthesis of sensitized photographic materials agent, in the printing and dyeing, paper making industry has been widely used.
1. As a textile dyeing and printing auxiliaries, which are widely used in vat dyes and sulfur dyes dyeing, wool silk fabric dyeing disperse the bleach reduction, a variety of colored fibers in color processing, cleaning pots and so on.
2. As deinking pulp bleaching agent (FAS) effective, used in paper industry in the bleaching of pulp, waste paper deinking.
3. In the polymer materials used in industry: a catalyst for synthetic resin, stabilizer, photographic exposure of the stabilizing agent, in pharmaceutical, medicine, spices and other fine chemicals and precious metals in the recovery and separation methods are applied.
