    摘要: A machine for distributing material from a package of compressed loosefill insulation material is provided. The machine includes a lower unit having a front panel. A shredding chamber is bounded on one side by the front panel and the shredding chamber receives compressed loosefill insulation material from a source of compressed loosefill insulation material. The shredding chamber including a plurality of shredders for shredding, picking apart, and conditioning the loosefill insulation material. A discharge mechanism is mounted to receive the conditioned loosefill insulation material exiting the shredding chamber and to distribute the conditioned loosefill insulation material into an airstream. A removable front access assembly covers a portion of the front panel of the lower unit and includes a control panel having a plurality of control devices. Removal of the removable front access assembly makes the plurality of shredders and the discharge mechanism within the lower unit accessible for inspection, replacement, or repair.

    摘要: Various exemplary aspects are directed to mineral wool plant substrates comprising mineral wool fibers bound by a binder formed from an aqueous binder composition comprising a cross-linking agent comprising at least two carboxylic acid groups; a polyol component having at least two hydroxyl groups; a nitrogen-based protective agent; and from 0.05 wt. % to 0.7 wt. % of a non-ionic surfactant. Methods of manufacturing such fiber-based plant substrates can include collecting a plurality of inorganic fibers on a substrate; applying an aqueous binder composition to the collection of inorganic fibers, forming binder-coated inorganic fibers; and curing the aqueous binder composition at a temperature less than 510° F., thereby forming a fiber-based plant substrate, wherein said aqueous binder composition is free of formaldehyde.
