A coverboard panel may include a first facer layer including a non-porous synthetic polymer, a core layer, and a second facer layer, wherein the core layer is disposed between the first facer layer and the second facer layer, and wherein the coverboard panel is configured to be installed with the first facer layer bonded to a membrane.

Water-resistant roof coverboard panels

A method of maintaining a belt of a continuous press configured to compress a mat comprising plastic elements includes applying a cleaning tool to the belt to remove plastic residue from the one or more plastic elements that has adhered to the belt and combusting the residue that accumulates on the cleaning tool.

Method of composite panel detachment from a heated and cooled press

In accordance with some aspects of the present disclosure, a method producing a composite board comprising plastic and cellulose is described. The method includes transmitting a first signal to a pair of opposing hot-platens, receipt of the first signal causing the pair of opposing hot-platens to compress and heat a composite mat; transmitting a second signal to the pair of opposing hot-platens, receipt of the second signal causing the pair of opposing hot-platens to heat and compress the composite mat at substantially a first pressure for a first time period; transmitting a third signal to the pair of opposing hot-platens, receipt of the third signal causing the pair of opposing hot-platens to release the composite mat from the first pressure; and transmitting a fourth signal to a pair of opposing cold-platens, receipt of the fourth signal causing the pair of opposing cold-platens to compress and cool the composite mat.

Rapidly heating and cooling composite mats comprised of cellulose and thermoplastic polymer

A method may include forming a mat including paper fragments, plastic fragments, and top and bottom outer surface layers, wherein the outer surface layers have maximum processing temperature values and consolidating the formed mat in a continuous hot press including three pairs of opposing top and bottom heating platens. A first pair of heating platens has a first heating power. A second pair of heating platens has a second, lower heating power. A third pair of heating platens has a third, even lower heating power. The method may include consolidating the formed mat in a continuous cold press including three pairs of opposing top and bottom heating platens. A first pair of cooling platens has a first cooling power. A second pair of cooling platens has a second, lower cooling power. A third pair of cooling platens and has a third, even lower cooling power.

Heat transfer system with improved efficiency for composite panel production

A method may include placing a bottom facer on a conveyor, placing a core layer on the bottom facer placing a top facer on the core layer, and pressing the bottom facer, the core layer, and the top facer in a hot press to form a panel, wherein the hot press causes the bottom facer to shrink relative to the top facer, introducing a warp into the panel such that, when installed, the warp compensates for an installation warp and the panel is flat upon installation.

Cup-resistant roof coverboard panels

Disclosed herein is a roof cover board and a method of manufacturing an improved cover board product. The method includes receiving waste materials or first use materials, the waste materials or first use materials containing a mixture of cellulose, plastic and other materials; separating the cellulose and the plastic from the mixture; shredding the separated cellulose using a first shredder into a stream of cellulose and shredding the separated plastic using a second shredder into a stream of plastic; selecting a cellulose to plastic ratio from a plurality of cellulose to plastic ratios; metering shredded cellulose from the stream of cellulose and shredded plastic from the stream of plastic according to the selected cellulose to plastic ratio; mixing the metered shredded cellulose and plastic; forming said mixture into a mat; and consolidating the mat into a finished good using heat and pressure.

Manufacturing method with improved fragment size and plastic-to-paper ratio

A method may include pressing a mat including a blend of paper and plastic fragments by applying a pressure to the mat using a heated press such that the mat is compressed to a first thickness, where the pressure is greater than a critical pressure threshold such that at least a portion of a moisture content of the mat is in a super-heated liquid state. The method may include maintaining the pressure on the mat above the critical pressure threshold until at least a portion of the plastic fragments of the mat are melted. The method may include decreasing the pressure on the mat below the critical pressure threshold such that the mat expands to a second thickness greater than or equal to a target thickness, and such that the portion of the moisture content of the mat in the super-heated liquid state is converted to steam.

Rapidly pressing mixtures of paper and plastic to targeted thickness and density

Disclosed herein is an improved cover board product with a panel comprising a top surface layer comprised of paper or a fiberglass web; a bottom surface layer comprised of paper, a fiberglass web, nylon film, polyester film, polypropene film, or textiles; and a core layer comprised of paper and thermoplastic fragments connected by a thermoplastic bonding resin. The thermoplastic bonding resin is in a random pattern to less than 100% of the paper and thermoplastic fragment surface area.

Roof cover board derived from engineered recycled content

A method of processing municipal solid waste includes extracting food waste, inert materials, and ferrous and non-ferrous metals from the municipal solid waste, shredding the municipal solid waste and thereby generating a product feed comprising at least 99.7% by volume cellulose-based materials and plastic. The product feed is conveyed to a forming system and a manufacturing product is created out of the product feed with the forming system.

Converting recyclable materials into manufacturing products

A system includes a displacement-type capacitive sensor probe and at least one processor and at least one memory. The at least one memory stores instructions that, when executed by the at least one processor, cause the at least one processor to calibrate the sensor probe to a known dielectric constant of a first material, send an instruction to the sensor probe to measure a capacitive response of a composite article comprising the first material and a second material, receive the measured capacitive response from the calibrated sensor probe, determine, based on the measured capacitive response, an equivalent thickness of the first material in the composite article, and determine a percentage of the first material in the composite article based on the equivalent thickness of the first material and a thickness of the composite article.

Determining plastic or cellulose levels in composites

This disclosure is directed to methods of separating wood veneer material by property measurements, and thereafter improving the properties of veneer material with property values lower than a target threshold value, until those materials meet or exceed that threshold values. In some aspects of the disclosure, veneer materials are prepared, non-destructively measured, and separated into passing and failing material collections. The failing material collection may then be treated to improve the density and flexural modulus of the material therein. Also disclosed herein are products and materials incorporating the treated veneer materials according to the disclosed methods.

Truncating the distribution of modulus properties in natural populations of wood

A non-destructive and non-contact test system quantifies the cellulose and/or plastic content in a given composite material board sample using capacitive sensors. The system includes a ground plate and a capacitive sensor probe system with programmed instructions to calibrate to a predetermined dielectric, determine, in a composite board placed in between the capacitive sensor and the ground plate, an equivalent thickness of material emitting the predetermined dielectric, and convert the equivalent thickness into a weight percentage of the material in the board.
