201 | CLAY PIGEON AND A METHOD FOR THE PREPARATION THEREOF | EP94924902.3 | 1994-08-30 | EP0721437B1 | 1998-11-04 | BRANDER, Kim; RISTIMÄKI, Asko; EEVA, Antti |
The object of the invention is a clay pigeon which is a saucer-shaped compressed piece made of clay and one or more additives. According to the invention, one of the additives is a calcium-based compound which reduces the drying shrinkage of clay and stabilizes the clay, which is preferably limestone powder or mortar. The clay content is at least 50 % and the additive content 5 - 50 %, calculated from the dry matter of the clay pigeon. The clay pigeon may also contain another additive reducing drying shrinkage and a component improving the plasticity of the mass. The invention also comprises a method for preparing a clay pigeon, where clay, one or more additives, and possibly a component improving the plasticity of the mixture are mixed to form a mass. Water is added if necessary to improve the plasticity of the mass, the mass is fed into a mould in which it is compressed for a moment, and the clay pigeon is removed from the mould while still in a plastic state. | ||||||

203 | Method of, and apparatus for drying shaped ceramic bodies | EP98105533.8 | 1998-03-26 | EP0867421A2 | 1998-09-30 | Sato, Ritsu |
Method and apparatus for quickly drying shaped ceramic bodies (3) having a complex surface (3a, 4a) with enriched unevenness, and a simple surface (3b, 4b) which is less uneven as compared to the complex surface (3a, 4a), without causing drying cracks and within a shortened time. The shaped ceramic body (3) within a drying chamber (1) is primarily heated from the simple surface (3b, 4b) by a main infrared heater (6), which is arranged on the simple surface side. Preferably, the ceramic body (3) is also heated by an auxiliary infrared heater (7) of a relatively low temperature, which is arranged on the side of the complex surface (3a, 4a), or dried while admitting a hot air into the drying chamber (1) with a low speed. |

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von keramischen Produkten, insbesondere dünnwandigen Rohren. In einem Aufbereitungsprozeß wird eine keramische Formmasse bereitgestellt, die aus mindestens einer bildsamen (plastischen) Komponente und aus mindestens einer unbildsamen (inerten) Komponente besteht. Um derartige Produkte mit im wesentlichen keiner Beschränkung der Anteilsverhältnisse zwischen den beiden Komponenten auf der -Basis von isostatisch gepreßten Formlingen herstellen zu können, wird ein spezieller Aufbereitungsprozeß für die keramische Formmasse vorgeschlagen. Bei diesem Aufbereitungsprozeß ist zunächst eine Zerkleinerung der die unbildsame und die bildsame Komponente bildenden Substanzen vorgesehen. In einem Umhüllungs- und Granulierprozeß wird dann die unbildsame Komponente im wesentlichen vollständig mit der bildsamen Komponente überzogen, wobei im Verlauf des Granulierprozesses die Primärkörner in Sekundärkörner mit sphärischer Form überführt werden. Anschließend wird die noch feuchte Formmasse zu der für das isostatische Pressen erforderlichen Preßfeuchte getrocknet. |

207 | LOW MOISTURE THIXOTROPIC AGENTS, METHODS AND USES. | EP92919367 | 1992-07-13 | EP0650466A4 | 1995-02-28 | BROOKS LAMAR E; BROOKS GERALD L |
Thixotropic Fuller's earth clay minerals which are structurally double silica chains linked together through oxygen to form double-ribbed sheets held by aluminum and/or magnesium in octahedral coordination in an amphibole chain are vacuum dried and admixed with a stabilizing fluid, e.g., silicone fluid, to result in new, low moisture content thixotropic agents. The mineral products thus produced are superior thixotropes when compounded in plastics such as plastisols, adhesive sealants, coatings and other organic binder systems which are heat set or heat cured or moixture cured, and compliance coatings. The methods involve reducing the moisture content of Fuller's earth clay, e.g., attapulgite, by (1) heating it under vacuum at an elevated temperature, preferably between 100 C and 300 C, or (2) heating it at an elevated temperature, preferably between 100 C and 350 C, and adding a stabilizing fluid, or (3) heating it under vacuum at an elevated temperature, preferably below 300 C and adding a stabilizing fluid, to preserve its low moisture properties. | ||||||

Procédé de production d'une boue aqueuse d'argile de kaolin de forte brillance et à haute teneur en solides. Une suspension aqueuse à faible teneur en solides d'une argile de kaolin brute est débarrassée du sable ou gravier, et est soumise à un classement granulométrique. La suspension aqueuse de la fraction de particules fines est acidifiée jusqu'à un pH de 5,0 ou moins afin d'obtenir une suspension acide de floculation qui est traitée avec un agent de blanchiment pour réduire les impuretés d'ions ferriques en impuretés d'ions ferreux. Un agent de chélation d'ions ferreux est ajouté à la suspension blanchie d'acide de floculation, après quoi l'on ajoute un agent alcalin pour augmenter le pH jusqu'à un niveau supérieur à 5,0 afin de former une suspension aqueuse dispersée du kaolin enrichi. La suspension dispersée est ensuite soumise à une filtration par membrane pour la dessécher partiellement, et de l'eau additionnelle s'évapore thermiquement de la suspension de kaolin dispersé partiellement desséché pour finalement obtenir la suspension de produit à teneur élevée en solides. | ||||||

On procède au moulage d'un article en introduisant un matériau contenant de l'eau tel qu'une barbotine dans un moule souple, en retirant ou séparant une quantité d'eau de ladite barbotine, par exemple, par centrifugation, décantation ou évaporation, et ensuite en congelant le moule et son contenu pour permettre de retirer du moule sans l'endommager l'article formé cru. On laisse sécher l'article formé cru, puis on le cuit selon la manière classique. La congélation du moule permet d'obtenir un article finement détaillé comportant beaucoup de contre-dépouilles, et ce à partir d'un corps en argile coulé dans un moule unique. | ||||||

213 | Refractory material produced from red mud | EP88311165.0 | 1988-11-25 | EP0318305A3 | 1990-05-23 | Allaire, Claude |
The invention relates to a process for producing a refractory material and to the material so-produced. The process comprises calcining red mud obtained as a by-product of the Bayer process of producing alumina, grinding the calcined product to form particles of -4 Tyler mesh, mixing the ground product with a binder (e.g. colloidal silica, colloidal alumina, sodium silicate or sodium aluminate) and sufficient water to produce a formable mixture. The mixture is then formed into a desired shape and fired, preferably after curing and drying. The resulting fired products have good resistance to high temperatures and to corrosive chemicals such as cryolite. Consequently, the products can be used as refractory linings for aluminium production cells, and in similar applications. |

215 | METHOD FOR MANUFACTURING HONEYCOMB STRUCTURE | US15921885 | 2018-03-15 | US20180283784A1 | 2018-10-04 | Kensuke Okumura |
A method for manufacturing a honeycomb structure, includes: a step of manufacturing a honeycomb formed body to manufacture a non-fired honeycomb formed body, the non-fired honeycomb formed body including a raw material composition containing a ceramic raw material and water; an induction drying step of drying the manufactured non-fired honeycomb formed body by induction drying to obtain a honeycomb dried body; and a firing step of firing the obtained honeycomb dried body to obtain a honeycomb structure. The induction drying step is to remove 10 to 50% of the entire water that the non-fired honeycomb formed body contained before drying by induction drying to obtain a first dried honeycomb formed body, then turn the first dried honeycomb formed body upside down and remove the residual water by further induction drying to obtain the honeycomb dried body. | ||||||

There is provided an apparatus and process for manufacturing a brick or paver with a high content of coal ash (ranging from 60% to 100% coal ash or fly ash) so that a waste product (coal ash, and more particularly Class F coal ash) from a coal-fired power plant is incorporated into a building product (high content fly ash brick or paver). Also provided is a variable firing tray to support the dried, high content coal ash bricks/pavers as the dried products are sent through a tunnel kiln, to improve circulation around the individual bricks/pavers and thereby result in reduced firing time in the kiln. | ||||||
