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 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.
摘要翻译：回收系统回收用于清洁生产部件的过剩粘合剂和碎屑的洗涤水，包括用于制造玻璃纤维绝缘体的由非腐蚀性材料构成的成型罩。提供了一种单独的闭环回收系统，用于成型罩壁，其中含有粘合剂的洗涤水被筛分，然后再循环回到成型罩壁，而无需进一步的化学处理以改变pH水平。粘合剂回收系统耦合到罩壁洗涤水回收系统以在需要在成型罩壁上补充粘合剂供应时转移低pH洗涤水。粘合剂回收系统将酸溶液引入清洁的洗涤水中以将pH从约2.5至约3.5降低。其他生产组件共享大量洗涤水回收系统，其中引入碱溶液以将pH升高至约8或更高，以减少其他生产组分中的腐蚀。

摘要： A binder composition, obtained by polymerizing acrylic acid monomer in water in the presence of a cure accelerator comprising an alkali metal salt of a phosphorous-containing inorganic acid to form a low molecular weight polyacrylic acid and subsequently reacting said low molecular weight polyacrylic acid with a polyhydroxy crosslinking agent in a crosslinking step to make a composition suitable for use as a component in a binder for fiberglass. A significant improvement involves conducting the crosslinking step in the absence of added catalyst. Moreover, satisfactory results are obtained in the absence of conventional undesirable sulfur odors.

摘要： Biocides for bio-based binder compositions are disclosed. Bio-based binders include those having a nutrient source such as carbohydrate, protein or fat, which can serve as an energy source for organisms to grow in areas that contact binder. Principal areas that contact bio-based binder in a fiberglass insulation manufacturing process include the raw ingredients, the binder chemicals, the prepared binder dispersions, the forming hood and related equipment, the final insulation product and, importantly, the cleaning systems and washwater arising from cleaning the manufacturing equipment and/or forming the product. Frequently the washwater is stored until re-cycled for re-use. Storage may take place in tanks, towers, vats and even outdoor reservoirs, all of which may harbor the growth of unwanted organisms, for which a biocide is desirable.
