A method for improving the air and/or water barrier performance of a building panel is disclosed. The building panel may be a gypsum board or cement board. In particular, the board may have improved resistance to bulk water penetration or permeation while maintaining breathability with respect to water vapor.

The present invention describes a method for preparing graphene by mixing graphite and carbon nanofibrils. The prepared graphene can be used to form nenopeper. The present invention also provides a method of preparing nanopaper by suspending cellulose nanofibrils and graphene, followed by vacuum filtering of the suspension.

A pulp molding machine and split heater plate assembly are contemplated for the manufacture of molded pulp products. The heater plate assembly is split into upper and lower planar members, with grooves formed at the interfacing area of these members and individual cartridge heaters disposed in these grooves. Use of this split heater plate reduces the difference in set temperature of the heater and the observed surface temperature of tooling affixed to the top of the split heater plate, while also delivering up to 15% improvements in the speed of the manufacturing operations relying on that split heater plate.

The present invention is directed to methods and systems for manufacturing molded fiber products using a pulp slurry and apparatus submerged in pulp slurry. The system utilizes a vacuum and mesh shaping of the product to pull fiber from the pulp slurry to the mesh shape while sucking the water through the mesh shape. The molded fiber product is then pressed to bolster the strength and structure of the product. The product is then coated using centripetal force to uniformly spread the coating across the selected area of the product. After coating, the product is pressed again to ensure the waterproof and airproof structure of the product. The materials used in manufacturing the molded fiber product are biodegradable, and the apparatus to form the molded fiber product is shaped according to the desired shape and size of the product.

A sheet assembly comprises a first grid comprising a first plurality of shapes on the sheet and a second grid comprising a second plurality of shapes on the sheet. The second plurality of shapes overlay the first plurality of shapes such that the second plurality of shapes are in a center of one or more squares defined by the first plurality of shapes. The first grid in combination with the second grid creates a template for the creation of one or more discrete components such as a list, a table, a chart and a graph. In some embodiments, the first grid comprises a plurality of crosshair shaped plus signs and the second grid comprises a plurality of dots. The two grid patterns are overlaid and offset from one another. The two patterns are offset such that the dots are located at the center of the squares defined by the crosshairs.
