Sinhon thiourea | Benefits of thiourea used in alkaline cleaners

The use of thiourea (CS(NH₂)₂) in alkaline cleaning agents can bring a variety of benefits, especially in the field of metal finishing and industrial cleaning. Here are some of the main advantages of thiourea in alkaline cleaners:

1.Enhance the cleaning effect Improved dirt removal
• Chelation: Thiourea has a certain chelating ability to form stable complexes with metal ions, thus effectively removing oxides, rust and other inorganic dirt from metal surfaces.
• Dispersion: Thiourea can help disperse oil and organic contaminants, preventing them from redepositing on the surface being cleaned. Improve cleaning efficiency
• Synergistic effect: thiourea has a good synergistic effect with alkaline components (such as sodium hydroxide, sodium carbonate, etc.), which can significantly improve the overall cleaning efficiency of the cleaning agent.
• Reduced cleaning time: Since thiourea enhances the decontamination ability of the cleaning agent, an effective cleaning process can be completed in a shorter time, improving production efficiency.
2. Protect the metal surface from corrosion
• Corrosion inhibition: Thiourea can form a protective film on the metal surface, preventing oxygen and water molecules from directly contacting the metal surface, thereby inhibiting corrosion and reducing the corrosion phenomenon that may occur during the cleaning process.
• Passivation: For some metals, thiourea can help form a passivation layer, further enhancing the corrosion resistance of the metal surface. Reduces scratches and damage
• Lubrication: Thiourea has some lubricating properties that can reduce damage to metal surfaces caused by mechanical friction during the cleaning process, avoiding scratches or abrasion.
3. Environmentally friendly and low toxicity
• Relatively safe: Compared to the highly corrosive substances or toxic chemicals found in some traditional cleaning agents, thiourea is less toxic and less harmful to operators and the environment.
• Easy to handle: Thiourea has relatively few decomposition products, reducing the difficulty of wastewater treatment and reducing the environmental impact.
4. Improve the performance stability of cleaning agent
• Stable pH: Thiourea helps maintain the pH value of the cleaning agent solution in a relatively stable range, ensuring the effectiveness and stability of the cleaning agent throughout its lifecycle.
• Antifreeze properties: In some cases, thiourea can also impart certain antifreeze properties to the cleaning agent, allowing it to maintain good fluidity in low temperature environments.
5. Economic benefits and cost-effectiveness
• Reduced dosage: Since thiourea enhances the effect of the cleaning agent, the amount of other ingredients can be reduced while maintaining the quality of cleaning, thereby reducing costs.
• Extended service life: By reducing damage to equipment and materials during the cleaning process, thiourea can help extend the service life of related equipment and materials, indirectly reducing maintenance costs.

Excellent service, reliable quality, delivering more value.
