摘要:
Es wird ein farbiges Oberflächenmaterial zur Anbringung auf Substraten, insbesondere den Oberflächen von Möbelstücken, Bauelementen u.dgl., beschrieben. Das'Oberflächenmaterial umfasst eine Kunststofffolie, die zumindest partiell durchsichtig oder durchscheinend ist, und das Material weist auf der dem Substrat zugewandten Seite eine Schicht aus einem farbigen Lack auf. Durch diese Konterfärbung entsteht der Eindruck eines durchgehend gefärbten Oberflächenmateriales. Ferner wird ein Gegenstand beschrieben, der ein Substrat aufweist, das mit einem derartigen Oberflächenmaterial versehen ist.

Multi-layered cellular metallic glass structures and methods of preparing the same are provided. In one embodiment, the cellular metallic glass structure includes at least one patterned metallic glass sheet and at least one additional sheet. The at least one patterned metallic glass sheet may include multiple sheets connected together to form a group of sheets, and the structure may include a group of sheets sandwiched between two outer sheets. The patterned metallic glass sheets may be patterned by thermoplastically forming two- and/or three-dimensional patterns in the metallic glass sheets. The metallic glass cellular structures are useful in a wide variety of applications, including but not limited to blast protection applications, energy absorption applications, structural support applications, biomedical implant applications, heat exchanger applications, thermal management applications, electrical shielding applications, magnetic shielding applications, and debris and radiation shielding for aerospace and outer space applications.
摘要:
Provided are a laminate that has high smoothness, planar homogeneity, and substrate adhesion and undergoes little change in physical properties even if degradation of surface quality due to physical contact in use has occurred, and a method for producing the homogeneous laminate in a convenient manner in a small number of steps. A laminate includes a substrate made of a polymer material and a partially oxidized thin layer graphite piece layer including partially oxidized thin layer graphite pieces and having an average thickness ta of 3.0 nm to 10,000 nm, the layer being formed on the substrate and bonded to the substrate via a chemical bond.
摘要:
The present disclosure provides a tie-layer adhesive comprising a first polymer composition comprising a grafted polyethylene, a second polymer composition comprising a polyethylene derived from a metallocene catalyst, a third polymer composition that comprises low density polyethylene. In general embodiments, the tie-layer adhesive comprises a primary additive and/or a secondary additive.
摘要:
Covers for sealing and/or bonding with an exposed surface of an animal feed within a container include a flexible film that conforms to the animal feed and a rigid or semi-rigid layer that allows the cover to be handled by an operator during placement of the cover over the animal feed composition while the composition is at elevated temperatures. The polymer film may include a heat-activated coating that establishes a bond with the animal feed when the feed is at elevated temperatures or when an external heat source is applied to the cover. The heat-activated coating may be flowable at a temperature of at least about 125 °F (52 °C). Upon placement of the cover over the animal feed, the film conforms to the exposed surface of the feed and the cover forms a seal with the animal feed as flowable coating reaches a flowable temperature.
摘要:
A shock absorption structure (S1, S2) includes: an exterior member (11) made of a first fiber-reinforced composite material; an interior member (12) made of a second fiber-reinforced composite material; and an intermediate member (13) extending along the exterior member (11) and the interior member (12) and sandwiched between the exterior member (11) and the interior member (12). The intermediate member (13) has a lower elongation percentage than the exterior member (11) and has lower strength than the exterior member (11).
