The application relates to a plastic moulding for a moulding arrangement including a housing for another plastic moulding of the moulding arrangement, wherein the housing is formed within a moulding body of the plastic moulding including a weldable material in at least some areas. It is contemplated therein that a contact element is arranged on the moulding body, the contact element at least partly including an electrically conductive material and limiting a recess of the moulding body adjoining the housing in at least some areas. The application further relates to a moulding arrangement and a method for producing a moulding arrangement.

The invention relates to a method for producing a tread (20), comprising the steps: extruding the tread (20), which has an outer side (22) and an inner side (24), opposite the outer side (22), and a carrying region (26) made of a carrying region rubber material and a guide strip (28) made of a guide strip rubber material, wherein the guide strip (28) extends from the outside (22) to the inside (24) and a specific electrical guide strip resistance (W.sub.28) of the guide strip rubber material is smaller than a specific electrical carrying region resistance of the carrying region rubber material. The steps according to the invention are: determining an electrical guide strip resistance (W.sub.28) of the guide strip (28) between the outer side (22) and the inner side (24) and outputting a warning signal when the electrical resistance (W) exceeds a specified maximum resistance (W.sub.28,max).

The present invention is directed to fiber composite structures, including one or more composite fibers or igneous rock fibers, such as basalt fibers and/or andesite fibers, that are impregnated with a polymer resin and subsequently coated with a frictional additive, such as aluminum oxide. The frictional additive provides for improved frictional engagement when the fiber composite structures are included in concrete or other structural materials and reduces alkaline degradation of the composite structures within the concrete over time. A process for manufacturing the fiber composite structures is also described herein. The process includes inductive heating of the fiber composite structures in order to cure the polymer resin, so as to affectively apply heat without being impeding by the external layer of frictional additive.

The present invention includes composition and methods for a core matrix comprising a dissolved cellulose fiber of, e.g., high molecular weight (DP>5000) or microcrystalline cellulose of low molecular weight (DP: 150-300), printed into a two or three dimensional pattern; a conductive material comprising a carbon nanotube or graphene oxide disposed on or about the cellulose fiber or microcrystalline cellulose; and an enhancer or stabilizer that stabilizes the dissolved cellulose or microcrystalline cellulose disrupted during a printing process, wherein the conductive material and the cellulose or microcrystalline cellulose forms one or more features in or on the cellulose fiber or microcrystalline cellulose.

Disclosed is a method for preparation and activation of a super hydrophobic electret nanofibrous filter material for cleaning PM2.5, comprising the steps as follows: (1) dissolving polymer powders and resin into a corresponding solvent so as to prepare a polymer solution, then stirring on a magnetic stirrer and standing for use; (2) in order to reinforce the electrostatic effect of the fiber, before preparing the polymer solution, adding in organic electret nanoparticles into the solvent, then oscillating with an ultrasonic oscillator; (3) in order to reinforce the super hydrophobic effect of the filter, spraying a low surface energy solution on the prepared nanofiber with a designed nozzle to carry out modification.

In an example method for forming three-dimensional (3D) printed electronic parts, a build material is applied. An electronic agent is selectively applied in a plurality of passes on a portion of the build material. A fusing agent is also selectively applied on the portion of the build material. The build material is exposed to radiation in a plurality of heating events. During at least one of the plurality of heating events, the portion of the build material in contact with the fusing agent fuses to form a region of a layer. The region of the layer exhibits an electronic property. An order of the plurality of passes, the selective application of the fusing agent, and the plurality of heating events is controlled to control a mechanical property of the layer and the electronic property of the region.

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.

A positive electrode (10) for an air cell of the present invention includes: a catalyst layer (11) composed of a porous layer containing electrical conductive carbon (1), a binder (2), and a catalyst component (3); and a fluid-tight gas-permeable layer (12) composed of a porous layer containing an electrical conductive carbon (1a) and a binder (2). The fluid-tight gas-permeable layer is stacked on the catalyst layer. This configuration can facilitate series connection of the air cells while preventing electrolysis solution from leaking out of a positive electrode. It is therefore possible to enhance the manufacturing efficiency and handleability of the air cells.
