摘要:
A method for producing a substantially rod-shaped composite body (6) consists of a core (4) enveloped by at least one polymer, according to which the plasticized polymer (5) is extruded onto the core (4). At least one natural polymer is used and a sliding agent on the basis of native oils and/or waxes is added before or during extrusion. The method is used for the production of writing, drawing, cosmetic pencils.
摘要:
A plastic material made from a polymer blend, is characterized in that said material contains at least one lignin-based natural polymer, in particular based on alkali lignin produced during the extraction of cellulose, and at least one other synthetic and/or natural polymer which increases the impact resistance, proteins excluded. The inventive plastic material has excellent characteristics. It is biodegradable due to the natural polymer content and has, to a considerable extent, an ecologically neutral CO2 balance. The polymer blend can be used advantageously in place of wood or wood materials.
摘要:
The invention concerns a composition for the production of shaped bodies, consisting of polymer lignin, shellac and natural fibers and also a method for the production of shaped bodies from such a composition via production of a shaped body through extrusion.
摘要:
The invention relates to a self-defence module comprising a housing containing a chamber that holds a free-flowing active medium and comprising a compressed gas source for spontaneously dispensing the active medium from the chamber. In order to be able to miniaturise the self-defence module, the compressed gas source is configured from a pyrotechnic gas generator and an ignition unit that interacts with the generator. According to the application, the ignition unit can be triggered manually or by a sensor. The invention also relates to the use of a self-defence module of this type for the protection of persons, buildings, means of transport or valuables.
摘要:
The invention relates to a device and a method for disabling electronic devices in order to reliably prevent third parties from gaining unauthorized knowledge of data in the event of loss of the storage medium. The device comprises a gas generator, with a pyrotechnic propelling charge, disposed in the area of the storage medium. At least one fuel or at least one oxidator of the propelling charge releases, when the latter is triggered, well conducting metals, especially precious or semi-precious metals which are deposited on the electronic parts of the electronic device. According to the inventive method, the igniter can be triggered manually, by sensors or remote-controlled. The invention further relates to an electronic data processing system and a telephone comprising such a device.
