Production and application of Sodium pyrithione copper pyrithione

Jan 23, 2019

The production of Sodium pyrithione copper pyrithione can be mainly divided into three steps. The first step belongs to oxidation reaction, and the sodium salt is reacted with hydrogen peroxide under the catalytic action of tungstic acid to obtain sodium oxide salt; the second step is acid. The main purpose of this step is to increase the purity of the sodium oxide salt, and the sodium oxide salt reacts with hydrochloric acid to form a solid form of the sulfhydryl compound.


Next, a salt reaction is carried out, and the sodium oxide salt is reacted with a copper sulfate pentahydrate solution, and then centrifuged and dried to obtain a Sodium pyrithione copper pyrithione. The appearance of the finished product is grass green crystalline fine powder. It is a bacteriostatic agent and anti-fogging agent for spectrum, low toxicity and environmentally friendly fungi and bacteria. It is widely used in civil coatings, adhesives and carpets. It is also used in marine antifouling paints. It can effectively organize the attachment of crustaceans, algae and aquatic organisms to the surface of the ship and the surface of the object without affecting the ecology.www.china-zhufengchem.com


The Sodium pyrithione copper pyrithione has low toxicity and stability, and thus can be used in the production of paints, so that the coating exhibits gel stability and prolongs storage time. At present, the Sodium pyrithione copper pyrithione market is widely used in the market, with large sales volume, great potential and wide space.
