Salt Bath Regeneration
Problem: Salt aging in the CV process
Anyone using salt molts today knows the problem that it is subject to aging. At the end, when a set quality is not met, the salt must be replaced. The liquid salt is cooled from over 400°C, disposed of at great expense and new salt must be melted again over several days. Material costs and downtimes therefore cause high process costs.
Salt baths age:
- – by enrichment of the exchanged ions
- – by decompose (depending on the process)
- – due to contamination (corrosion of the containers and supports)
Solution: Regeneration material from ReViSalt
Our customers benefit from our innovations by being able to use their salt baths for much longer. This not only reduces process costs, but also makes the entire process significantly more sustainable. It is extremely simple to use: Our regeneration material is dipped into the salt bath like a tea bag, remains there for 24 hours and can then be completely removed.
With our regeneration material, our customers can completely avoid the use of silica, which settles as sludge in the salt bath and is only effective to a limited extent.
Our regeneration material offers numerous advantages:
- + significantly extends the service life of the salt bath
- + ensures consistently high strength quality with lower tolerances
- + guarantees permanently high-quality glass surfaces without signs of corrosion
- + is fully recyclable
- + effectively removes sodium and lithium
- + regulates the pH-value of the salt bath
