    摘要: A process for the production of green ceramic preforms for dental parts involves introducing a model into ceramic slip in a slip container for coating the model. Ceramic slip is controllably drawn off from the slip container and the coated model removed. An apparatus for producing green ceramic preforms includes an opening in the slip container through which flow of the ceramic slip is controllable. The green ceramic preform may be used to produce a dental part. Conduit means are so arranged on the slip container that ceramic slip can be controlledly drawn off out of the slip container through the conduit means.

    摘要: A water based binder for use in a slurry for investment casting. The binder includes a mixture of a colloidal silica sol and at least one latex polymer. The latex polymer is preferably an acrylic latex or a styrene butadiene polymer (or a combination of these) which reduces the processing time between dips during shell mold making for investment casting. The latex polymer further lowers a critical concentration point or gelation point of the colloidal silica sol. The binder may be used as a primary binder or a backup binder in the shell mold making process. To make the slurry, the binder is combined with at least one refractory powder, preferably a refractory powder selected from the group of: alumino-silicates, fused silica, quartz silica, alumina, zircon, and zirconia.

In the laminated part 2, the lowermost layer is a natural rubber layer, and the top surface layer is all oil-resistant rubber layer (for example, an acrylonitrile-butadiene rubber layer). The glove manufacturing method according to the present invention comprises the steps of immersing a glove mold in natural rubber latex containing a heat-sensitive coagulant to form a coating of the lowermost layer on the mold surface, and immersing at least a part of the lowermost layer in another rubber latex different from the first-mentioned rubber latex. The glove of the present invention has high strength and is economical and excellent in oil resistance and solvent resistance.

    摘要: The present invention relates to an improved process and partible mold for forming a light-weight synthetic ceramic log for use in natural gas, propane and wood-burning fireplaces and stoves which are both fully-vented and non-vented depending upon the particular design of the heat generating equipment. In the subject process, a flexible porous patterned screen is formed simulating the exterior bark portion of a tree or log having a reverse image. Such screen is designed with both porous and non-porous surface characteristics for mounting as a separate element within the partible mold. The flexible porous patterned screen is mounted within the partible mold having major interior surface areas which are capable of connection to a vacuum source for withdrawing water from a liquid composition containing ceramic fibers to rapidly form the ceramic log within the mold during short periods of vacuum molding. After vacuum extraction of the liquid components of the molding composition containing multiple ceramic fibers, the partible mold is opened and the separable screen and newly-formed log are taken therefrom and separated, following which the synthetic log is dried to increase its structural strength for further handling and processing. The molding composition contains both finely-divided ceramic fibers such as aluminosilicate fibers and a colorant such as iron chromite to produce the ceramic log having a dark colorization. After the log is formed and dried, the log is then subjected to an additional colorizing operation to give its exterior surface areas greater colorization ranging from brown to gray to black depending upon the desired surface characteristics to be obtained.

    摘要: A process for rapidly forming a laminar ceramic shell mold on a supporting structure comprising alternately, in either order, the steps of: (1) dipping the support structure into a bath comprising either an alkali stabilized solution of ionic silicate or an alkali stabilized solution of colloidal silica to define a first coating on the support structure; and (2) dipping the support structure into a bath comprising an acid stabilized solution of phosphate modified aluminum salt to define a second coating on the support structure. The coatings on the support structure react to form a gel set shell which can be fired to a ceramic material. The dipping step sequence is repeated to provide additional coatings which react to define additional layers of gel set shell. The rate of laminate thickness buildup can be increased by including fine particulate refractory in the coating baths and the coated surface can be contacted by dry, relatively coarse refractory to define a stucco layer between the dip coatings. The chemically induced gel set eliminates the need for air drying between coating applications thereby saving a major portion of the total process time. When the laminar refractory is formed around a disposable wax pattern of a desired metal shape it produces a strong ceramic shell mold that fully meets the requirements for the precision casting of metals.
