Spray cleaning porcelain powder from monorail hangers
Mild steel hangers
A common problem in porcelain coating is the removal of porcelain overspray from part hangers and the subsequent processing of the removed porcelain powder. Porcelain powder is very hydrophobic and forms a solid cake in aqueous environments. This customer desired a cleaning solution that would efficiently wet the porcelain and allow it to maintain good flow properties for ease of removal from the cleaning bath.
MetaLube formulated a specialized cleaner to enhance removal of the porcelain from the hangers, and to allow easy separation of the settled powder from the bath. MetalKleen 4920 P efficiently wets the porcelain overspray and prevents settled powder from forming a solid cake. The customer is now able to pump the loaded process bath to a separator and drain the porcelain powder from the cone bottom. The bath can then be pumped back to the tank for re-use. This customer has greatly reduced the maintenance costs associated with weekly cleaning of their wash tank, and processing of the spent powder.
