摘要:
Hardness, ageing resistance, wetting behavior in relating to water and high thermal conductivity are known characteristics of sintered molded bodies consisting of aluminum oxide; high strength and a high resistance to cracking, i.e., damage tolerance are known characteristics of sintered molded bodies consisting of zirconium oxide. These properties are combined in a material having a large fraction of aluminum oxide, zirconium oxide and optionally strontium aluminate.
摘要:
Method for producing electrically conductive, structured or full-area surfaces on a support, in which a structured or full-area base layer onto the support in a first step by using a dispersion, which contains electrically conductive particles in a matrix material, the matrix material is at least partially cured and/or dried in a second step, the electrically conductive particles are exposed in a third step by at least partially breaking the matrix, and a metal layer is formed on the structured or full-area base layer in a fourth step by electroless and/or electrolytic coating.

摘要:
Media I suitable for the thermal transfer of a layer containa) a substrate II,b) a layer III thereon, containing1) from 75 to 90% by weight of a polymer IV having a softening point of from 100 to 160.degree. C., and2) from 10 to 25% by weight of a polymer V having a softening point of at least 90.degree. C.andc) a layer VI containing a polymer VII.
摘要:
The invention relates to a unit for a pneumatic brake system for a utility vehicle, which has a valve block into which magnet valves are inserted. To secure the magnet valves on the valve block, the unit includes a retaining plate which is secured to the valve block and which has spring elements integral with it the retaining plate presses the magnet valves into valve receptacles of the valve block. The unit has the advantage that the retaining plate balances out tolerances in the manufacture of the valve block and the production of the magnet valves. In a further feature, the unit mounts pressure sensors on the valve block in a same manner as the magnet valves.
摘要:
Magnetic recording media consist of a nonmagnetic substrate and at least one magnetizable layer bonded thereon and based on a magnetic material dispersed in at least one polyurethane and one polyurethaneurea (meth)acrylate, the polyurethaneurea (meth)acrylate being obtained by reacting a hydroxyl-containing poly(meth)acrylate with a mixture of di- and polyisocyanates and converting the remaining NCO groups with ammonia or primary or secondary amines into urea groups.
摘要:
Magnetic recording media are obtained by preparing a dispersion of anisotropic magnetic material and additives in a solution of a polymeric binder in an organic solvent, applying the dispersion as a layer to a nonmagnetizable substrate, then orienting the anisotropic magnetic material in a magnetic field and solidifying the applied magnetic layer, and the magnetic layer contains water-repellent polysilica and, if required, a highly viscous polysiloxane.
