摘要:
Die Erfindung betrifft eine Abdichtung für ein Betonelement, umfassend einen flächigen Träger und eine auf den Träger aufgebrachte Wirksubstanz, wobei die Wirksubstanz mit Wasser chemisch reagierend ausgebildet ist. Erfindungsgemäß ist der Träger flexibel.
摘要:
There is provided a cutting tool having high wear resistance and fracture resistance by reducing the occurrence of thermal cracking on a cutting edge even during a cutting process of a heat-resistant alloy in which the cutting edge reaches high temperatures. The cutting tool is made from a cemented carbide that is composed mainly of a WC phase and contains 11.5-12.5% by mass of Co and 0.2-0.6% by mass of Cr in terms of Cr 3 C 2 . The WC phase has a mean particle size of 0.85-1.05 µm, an antimagnetic force (Hc) of 13.0-16.0 kA/m, and a Rockwell hardness (HRA) of 89.5-90.5.
摘要:
The invention relates to a method for applying a cermet electrode layer to a sintered electrolyte. This layer consists of a mixture of an ion-conducting oxide and a semiprecious metal oxide or precious metal oxide. According to the invention, the ion-conducting oxide is calcined without the presence of the (semi)precious metal oxide in order to provide for lateral electron conductivity, while the sintering of the mixture on the electrolyte takes place at as low a temperature as possible.

Provided is a building material (10) that is lightweight, exhibits excellent formability, and is inhibited from being damaged during transportation, and a method for producing the same. Specifically, provided is a method for producing a building material (10), including: a first step of curing a core layer (1) material including a hydraulic material, a silica-containing material, and an aluminum powder, to react the aluminum powder and form bubbles, and incompletely hardening the hydraulic material and the silica-containing material, to form a foamed core layer (1); a second step of dispersing a surface layer (2) material including a hydraulic material, and a silica-containing material, to form an unfoamed surface layer (2); a third step of stacking the foamed core layer (1) on the unfoamed surface layer (2), to form a stack including the unfoamed surface layer (2) and the foamed core layer (1); and a fourth step of pressing and curing the stack, and a building material produced therewith.
