    摘要： 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 about 8.5, thereby substantially reducing the corrosion rate of the components of the equipment associated with acidic polyacrylic acid binder, maleic acid cobinder or maleic anhydride cobinder 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 and maleic acid cobinder or maleic anhydride cobinder with a minimal amount of base solution, thereby minimizing degradation of insulation properties of polyacylic acid bound glass fiber products.

    摘要： A recovery system recycles the washwater used to clean excess binder and debris from the production components, including a forming hoodwall constructed of non-corrosive materials, for manufacturing fiberglass insulation. A separate closed-loop recovery system is provided for the forming hoodwall in which the binder-containing washwater is screened and then recycled back to the forming hoodwall without further chemical treatment to change the pH level. A binder reclamation system is coupled to the hoodwall washwater recovery system to divert the low pH washwater when the supply of binder needs replenished at the forming hoodwall. The binder reclamation system introduces an acid solution to the cleaned washwater to lower the pH from about 2.5 to about 3.5. The other production components share a bulk washwater recovery system in which a base solution is introduced to raise the pH to approximately 8 or above to reduce corrosion in the other production components.

    摘要： A neutralization system for controlling the pH of the washwater used to clean and maintain polyacrylic bound glass forming equipment is provided. 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 and in a washwater tank holding the washwater solution is determined to be below approximately 8.0. Maintaining the pH of the washwater solution reduces the corrosion rate of the glass fiber forming equipment that is typically associated with acidic binders. In a second embodiment of the invention, a closed-loop hoodwall reclaim washwater recovery system utilized in addition to the washwater neutralization system that allows for the recovery and reuse of a polycarboxylic acid binder with a minimal amount of base solution. The closed-loop hoodwall reclaim washwater system is not connected to the closed-loop washwater neutralization system.

    摘要： A method of reducing formaldehyde emissions from a fibrous insulation product is provided. Fibers are formed, and a binder including a curable formaldehyde-containing resin is applied to the fibers to form a pack. The pack is introduced into a curing oven to cure the resin. During the curing, moisture is applied to the pack. For example, the moisture can be applied by injecting steam into the curing oven. The pack with the cured resin is removed from the oven. The pack is formed into the fibrous insulation product. The fibrous insulation product has reduced formaldehyde emissions compared to the same product without the moisture application.
