摘要:
2.1. Ein Herstellungsverfahren, bei dem ein kaltgepresster, hülsenförmiger Grünling auf einen Trägerkörper aufgesintert wird, ist bekannt. 2.2. Erfindungsgemäß wird der zu sinternde Grünling in eine zu gegenüberliegenden Seiten hin offene Aufnahmekammer einer auf Sintertemperatur beheizten Matrize eingebracht, und von den offenen Seiten der Aufnahmekammer her wird der Grünling auf gegenüberliegenden Seiten durch Pressmittel mit dem benötigten Sinterdruck beaufschlagt. 2.3. Einsatz für die Herstellung von Diamantperlen für Diamantsägeseile.
摘要:
A method for pressing powdered material to obtain tiles, comprises distributing powders on flexible conveyor means, advancing said powders along an advancing direction through a pressing station, containing laterally said powders on said conveyor means in said pressing station by side containing means distinct from said powdered material, and acting on the powders to be pressed during said advancing and continuing to act during pressing; an apparatus for pressing powdered material in such a way as to obtain tiles, comprises flexible conveyor means for receiving powders thereon from distributing means and for advancing said powders along an advancing direction through a pressing station, containing means for laterally containing said powders on said conveyor means, said containing means being distinct from said powdered material and arranged to act on the powders to be pressed during advancing and pressing of the powders.

A method of manufacturing plate-like ceramic articles comprises the steps of: delivering, according to a predetermined sequence, calibrated doses of powdery/atomized material from a storage, supplying, according to a predetermined sequence, said calibrated doses into at least one pair of shaping moulds, forming an article in each pair of shaping moulds by compacting powdered/atomized material loaded into at least one seat in said shaping moulds, removing each shaped article from its respective seat, transferring it to a pressing station, and pressing the shaped article for causing its permanent stabilization. An apparatus for carrying out such a method comprises a storage (14) for storing powdery/atomized materials and delivering metered quantities thereof, at least one shaping mould (10, 110; 11, 111) having at least one shaping seat (4, 104) provided in at least one shaping unit (3) arranged downstream of said storage (14) for receiving metered quantities of powdered/atomized material to be shaped to form at least one article (M) by being die-pressed therein, at least one press (6) located downstream of the or each shaping unit (3), and withdrawing means (5) located at each shaping unit (3) and designed to withdraw shaped articles (M) therefrom and to transfer them to a respective press (6) for permanent stabilization of said articles (M).
摘要:
Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a particle packed, highly inorganically filled, cellular matrix are disclosed. Suitable inorganically filled mixtures are prepared by mixing together a starch-based binder, a solvent, inorganic aggregates, and optimal admixtures, e.g., fibers, mold-releasing agents, rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria. The inorganically filled mixtures have a predetermined viscosity and are heated between molds at an elevated temperature and pressure to produce form-stable articles having a desired shape and a selectively controlled cellular, structure matrix. The molded articles may be placed in a high humidity chamber to obtain the necessary flexibility for their intended use. The articles may be manufactured to have properties substantially similar to articles presently made from conventional materials like paper, paperboard, polystyrene, plastic, or other organic materials. They have especial utility in the mass-production of containers, particularly food and beverage containers.
摘要:
Die Erfindung betrifft eine monolithische Bauplatte mit folgenden Merkmalen: einer rechteckigen Grundfläche, einer Matrix auf Basis eines anorganischen Bindemittels, sowie vier falzartig gestalteten Randabschnitten, jeweils zwei benachbarte Randabschnitte sind einteilig gestaltet, zwei benachbarte Randabschnitte weisen eine Grundfläche fluchtend mit einer ersten Hauptoberfläche der Bauplatte und eine gegenüberliegende Setzfläche mit Gefälle zu Außenkanten der Randabschnitte auf, die weiteren Randabschnitte sind mit einer Grundfläche fluchtend zu einer zweiten Hauptoberfläche der Bauplatte und einer Setzfläche mit Gefälle zu Außenkanten der Randabschnitte ausgebildet.
摘要:
Transfer means of granular material (15) includes a permeable baffle (33) through which a fluid acts on said granular material; it further comprises a thin belt (31) on which the said granular material lies, said thin belt being unwound from a coil (39) arranged upstream the pressing station and being rewound in coil (39) downstream the said pressing station; a method to prepare a layer of powders designed to be pressed in form of ceramic tile comprises the following steps: arranging on a support surface superimposed layers (310,312) of different powders; acting with a fluid on said superimposed layers of different powders to mix them with each other along a vertical direction.

摘要:
A novel product and a method for producing single- or multi-phase biological materials, e.g. composite and ceramic materials, from bioactive mineral powders such as calcium phosphate powders. Said method is characterised in that it involves dynamically compacting a sample containing at least said powder by means of a shock wave.
