Cleaning compositions and processes suitable for replacing grit blasting to clean metal mold surfaces for plastics |
摘要 |
Residue that accumulates on metallic molding surfaces during repeated molding of plastics such as PVC can be removed by cleaning with an aqueous solution of a glycol or oligo-glycol monoether, an amine, and a chelating agent. The cleaner is sufficiently effective to replace mechanical blasting that was previously required.
