Application Areas of the Compound Isoxazolinone (V529)

The compound isothiazolinone (V529) is a highly effective bactericide and fungicide with significant applications in various fields. The following provides a detailed explanation of its applications:

　　Industrial circulating water systems

　　In industrial production, numerous industrial circulating water systems require long-term stable operation, such as the cooling water circulation systems of steel plants, chemical plants, and thermal power plants. The water is rich in nutrients and easily breeds bacteria, fungi, and algae. These microorganisms form biofilms that adhere to the surfaces of pipes and heat exchangers, reducing heat exchange efficiency, increasing energy consumption, and even causing equipment corrosion and blockage. Compound isothiazolinone (V529), with its powerful bactericidal ability, can quickly inhibit and kill various microorganisms, effectively preventing the formation of biofilms, ensuring the smooth operation of industrial circulating water systems, extending the service life of equipment, and reducing maintenance costs and operational risks for enterprises.

　　Papermaking industry

　　The papermaking process involves a large amount of water. From pulp making to papermaking, the water temperature and organic matter content in pulp storage tanks and white water systems provide a breeding ground for microorganisms, easily leading to large-scale microbial reproduction. This not only affects the quality of the paper, such as causing spots and holes, but also corrodes papermaking equipment. Compound isothiazolinone (V529) can effectively control microorganisms in the water used for papermaking, ensuring the stability and high quality of paper production, while protecting equipment from microbial erosion, reducing downtime for repairs due to microbial problems, and improving the production efficiency of papermaking enterprises.

　　Paints and coatings

　　Paints and coatings are susceptible to microbial contamination during production, storage, and use, especially water-based paints. The water and nutrients they contain easily allow mold and bacteria to grow and reproduce. Once microorganisms grow extensively, it can cause discoloration, odor, changes in viscosity, and even layering or caking, severely affecting product quality and performance. Compound isothiazolinone (V529), as an effective preservative, added to paints and coatings, can inhibit the growth of microorganisms, ensuring that the product maintains good stability, appearance, and performance over a long period, extending the shelf life, and guaranteeing its effectiveness in various applications such as construction and furniture.

　　Leather processing

　　In leather tanning and dyeing processes, the processing water and nutrients in the leather itself easily cause the proliferation of microorganisms, leading to mold, decay, and reduced leather quality and yield. Compound isothiazolinone (V529) can provide bactericidal and preservative effects during leather processing, protecting the leather from microbial damage, resulting in high-quality leather with a good appearance, meeting the high standards of various leather products such as bags and shoes.
