ABSTRACT:
A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment. The neutralization system introduces a base solution to a washwater solution when the pH of the washwater solution contained in a closed loop washwater recovery system falls below approximately 8.0, thereby substantially reducing the corrosion rate of the components of the equipment associated with acidic polyacrylic acid binder and washwater solution. A closed-loop hoodwall washwater recovery system may also be introduced in addition to the neutralization system that allows for the recovery and reuse of polyacrylic acid binder with a minimal amount of base solution, thereby minimizing degradation of insulation properties of polyacylic acid bound glass fiber products.
