摘要： Embodiments of a system and a method for preparing mold-resistant paper comprising a wet scrubber assembly in fluid communication with at least one collection plenum disposed at an operational area of a paper manufacturing line. The wet scrubber assembly can be operated to draw a stream of exhaust air from the operational area of the paper manufacturing line through the wet scrubber assembly to remove particulate from the exhaust stream. Such systems and methods can be used to produce mold-resistant paper by coating a paper with an antimicrobial composition including at least one antimicrobial additive at the calendering stage. The collection plenum can be placed in proximate relationship with the calendering stack such that the amount of antimicrobial additive particulate in the air at the calendering stage is reduced. The mold-resistant paper can be used in a gypsum panel.

摘要： In this papermaking process, a first strength agent is added to a stock suspension containing pulp and optionally other additives prior to its being formed into a web at the wet end of a papermaking machine. The web is then formed and processed into paper. A second strength agent is then applied to the surface of the paper. The strength agents may be selected to have opposite charge.
