INTRODUCTION

Perchloroethylene, commonly known as Perc, is a colorless liquid solvent widely used in various industrial and commercial applications. It is known for its excellent degreasing properties and ability to dissolve oils, fats, and waxes without damaging the materials it cleans.

USES:

1. Dry Cleaning Industry

Perchloroethylene has been the primary solvent used by professional dry cleaners for decades due to its efficiency in removing stains and dirt from delicate fabrics without shrinking or damaging them.

Benefits of Perchloroethylene in Dry Cleaning:

Effective Stain Removal: It dissolves grease, oil, and organic stains effectively.
Fabric-Safe Cleaning: It does not weaken or shrink fabrics, making it ideal for delicate garments.
Quick Drying: Clothes dry faster, allowing for a more efficient cleaning process.

2. Metal Degreasing

Perchloroethylene is also extensively used in industrial metal degreasing to clean machine parts, tools, and components. Its strong solvency power makes it ideal for removing grease, dirt, and contaminants from metal surfaces before painting or coating processes.

Benefits of Perchloroethylene in Metal Degreasing:

Superior Cleaning Power: Removes oil, grease, and residues effectively.
Non-Flammable: Enhances safety in industrial settings.
Efficient Process: Ensures a clean, residue-free surface for subsequent treatments like painting or plating.

Safety and Environmental Considerations

While Perchloroethylene is highly effective, it must be handled with care due to its potential health and environmental impacts.

Proper Ventilation: Workspaces using Perchloroethylene should be well-ventilated.
Protective Equipment: Workers should wear gloves and masks to minimize exposure.
Regulations Compliance: Many countries have regulations on Perchloroethylene use to limit emissions and ensure safe handling.

CONCLUSION
Perchloroethylene remains a crucial solvent in both the dry cleaning and metal degreasing industries. Its powerful cleaning capabilities make it an essential material, but responsible handling and adherence to safety measures are necessary to minimize risks. As industries evolve, alternative solvents are being explored, but Perc continues to be a reliable choice for effective cleaning solutions.
