Waste plastic conversion
11993540 · 2024-05-28 ·

Waste plastic can be converted into rock for decorative and utilitarian applications. A combination of sand and waste plastic is added into a tumbling chamber, and the tumbling chamber is rotated. The combination of sand and waste plastic is heated while rotating the tumbling chamber to form conglomerates. When a desired size of the conglomerates is achieved, the heating is stopped. Dry cement is then added to the tumbling chamber while continuing to rotate the tumbling chamber.

POLYMERIC COMPOSITES WITH FUNCTIONAL SURFACES

A composite having a textured surface with multiple protrusions and a bulk portion. The composite includes a polymeric matrix and particles, the major amount of particles being concentrated into the textured surface. The composite can be used as a structural coating, super-repellent material, antireflective material, or antimicrobial material among others.

METHOD FOR MAKING OXYGEN REMEDIATING MELT-INCORPORATED ADDITIVES IN PLASTICS FOR PACKAGES
20190022900 · 2019-01-24 ·

A product and method for providing oxygen remediating extruded or other melt-phase plastics for packages for reducing oxygen-linked damage to foods, pharmaceuticals, or other oxygen sensitive substances. The method for making oxygen remediating melt-phase incorporated plastics for packages and packaging elements generally includes the addition of an oxygen managing combination of compounds that restrict the migration of oxygen and/or eliminate migration oxygen through reaction with components of the polymer additive. Dry components remain inactive until moisture from the packaged food partially deliquesces a formulary component to trigger oxidation of a powdered metal or other oxidizing compound. Other additives absorb and distribute moisture and facilitate electron movement for improved oxidation.

METHOD TO PRODUCE A WEAR RESISTANT LAYER WITH DIFFERENT GLOSS LEVELS

The present disclosure relates to a method to produce a wear resistant layer and a method to produce a building panel including a wear resistant layer. The wear resistant layer includes a thermoplastic material. The wear resistant layer is provided with portions having different gloss levels. The disclosure also relates to such a building panel.

Feedstocks for additive manufacturing and methods for their preparation and use

Feedstocks for additive manufacturing are provided. The feedstock may include a matrix material, and one or more capsules disposed in the matrix material, wherein the one or more capsules are configured to be removable from a surface portion when the matrix material is solidified to form one or more cavities in the surface portion. Methods of depositing the feedstocks and objects formed from the feedstocks are also provided.

Enhanced surfaces, coatings, and related methods

A method of modifying a coating material includes applying a fluid including a population of particles to a wet coating material disposed on a substrate. The method also includes drying the wet coating material so as to give rise to a coated article, where the particles are at least partially embedded in a surface of the dried coating material. The particles can be metallic nanowires, and a loading of the metallic nanowires in the dried coating material can be above an electric percolation threshold.

Antislip flexible materials and methods for their making and use

A method for forming an antislip material. A flexible thermoplastic carrier is provided. A hot release surface is provided. Provided is a first layer of discrete thermoplastic particles, sifting on the hot release surface. The discrete particles are above their softening temperatures, providing in the first layer a tackiness. The method includes contacting the carrier with the tacky first layer for sticking the first layer to the carrier, and thereafter removing the carrier, and therewith the tacky first layer stuck to the carrier, from the release surface. Thereby the carrier is provided with a hot, preferably discontinuous and/or elastomeric antislip coating. With a heat energy of the hot coating a bond is formed between the carrier and the coating. The removing of the carrier includes pulling the carrier out of the contact with a pulling-out force. The temperature of the hot release surface is above the melting temperature of the carrier. The carrier would be spoiled, if heated completely to the temperature of the release surface and simultaneously pulled with the pulling-out force. Therefore the contacting time is kept shorter than a minimum time required by a heat of the hot release surface for spoiling the carrier. Flat-topped roughening projections can be included in the antislip coating.

Method for producing a core brush comprising polyvinyl formalin bristles
10029399 · 2018-07-24 · ·

A method of producing a brush for the cleaning of electronic components. In this method, a plastic core is prepared and submerged into a solvent to melt the outer surface of the core. While the outer surface of the plastic core is still partially melted, it is rolled through a trough of powdered polyvinyl alcohol (PVA) such that granules of PVA melt into and subsequently become embedded at the outer surface. As the solvent evaporates, the outer surface of the core re-hardens and the granules of PVA become firmly entrapped at the outer surface. The PVA covered shaft is placed in a mold, which is then filled with a PVA solution. As the solution cures, it forms a strong bond with the PVA granules that are embedded at the surface of the plastic core. Thereafter, the mold components are disassembled, leaving behind the finished cored brush.
