1. Product Performance
THPS is an efficient, broad-spectrum, and environmentally friendly biocide used in industrial water treatment, oilfield operations, and textile processing.
- Chemical Formula: C4H12O8P2SC_4H_{12}O_8P_2S
- CAS Number: 55566-30-8
- Appearance: Colorless to pale yellow liquid
- Solubility: Completely soluble in water
- Stability: Stable under normal conditions but decomposes at high temperatures or in alkaline environments
- Biodegradability: Readily biodegradable, making it an environmentally friendly alternative to traditional biocides
2. Key Features
- Powerful Biocidal Action: Effective against bacteria, fungi, and sulfate-reducing bacteria (SRB) in industrial water systems.
- Low Toxicity and Environmentally Friendly: Easily biodegradable with minimal environmental impact.
- Strong Chelating Ability: THPS Can chelate metal ions, preventing scale formation and metal corrosion.
- Thermal Stability: Suitable for high-temperature environments, such as oilfields and industrial processes.
- Compatibility: Works well with other water treatment chemicals, such as scale inhibitors and corrosion inhibitors.
3. Applications
1) Water Treatment
- Used in cooling water systems, industrial circulating water, and desalination plants to control microbial growth.
- Prevents biofouling in pipelines, heat exchangers, and water storage tanks.
2) Oilfield Industry
- Commonly used in enhanced oil recovery (EOR) to prevent sulfate-reducing bacteria (SRB) that cause reservoir souring and corrosion.
- Applied in drilling fluids and hydraulic fracturing fluids to inhibit microbial contamination.
3) Textile and Leather Industry
- Acts as a biocide and preservative in leather processing to prevent microbial degradation.
- Used in textile bleaching and dyeing as a formaldehyde-free alternative for fabric finishing.
4) Paper and Pulp Industry
- Helps control slime-forming bacteria and fungi, reducing paper production downtime.
5) Metalworking and Corrosion Inhibition
- Applied as a corrosion inhibitor in metal treatment processes due to its strong chelating properties.
4. Advantages Over Traditional Biocides
- More environmentally friendly than traditional biocides like glutaraldehyde and isothiazolinones.
- Less corrosive to equipment compared to chlorine-based disinfectants.
- Highly effective at low concentrations, reducing overall chemical usage.
5. Handling and Storage
- Store in a cool, dry place, away from strong oxidizing agents.
- Use protective gloves and eyewear when handling concentrated solutions.
- Avoid prolonged exposure to high temperatures or alkaline conditions, which can reduce efficacy.
