    摘要: A mould liner for a fabrication assembly is disclosed. The fabrication assembly is for fabricating an elongate concrete article in a substantially upright orientation and includes a core assembly and an outer mould assembly defining a mould cavity between the core assembly and an inner moulding surface of the outer mould assembly with the outer mould assembly being separable following casting of the elongate concrete article to strip the outer mould assembly from the elongate concrete article. The mould liner during casting forms an intermediate layer between the inner moulding surface of the outer mould assembly and the elongate concrete article being cast, wherein on stripping of the core and outer mould assemblies following casting, the mould liner is adapted to form an outer containment layer to the elongate concrete article.

    摘要: A preparation method for an easily-releasable concrete test mould with an inner wall having ultra-hydrophobic/ultra-smooth performance includes spin-coating a negative photoresist and obtaining a substrate with an inner wall having inverted-trapezoid microstructures by ultraviolet lithography; depositing a metal layer by vacuum evaporation; removing the metal layer on an upper surface of the inverted trapezoid microstructures of the inner wall of the substrate; obtaining a micro-nano hierarchical structure on the metal layer surrounding the inverted trapezoid microstructures of the inner wall of the substrate; spin-coating a molten wax and cooling down to room temperature, and filling the solid wax into micron-level pores between the inverted trapezoid structures; spin-coating a positive photoresist and performing ultraviolet lithography; g. draining the solid wax out of the micron-level pores to obtain a substrate with an ultra-hydrophobic surface structure; and assembling the substrate to obtain an ultra-hydrophobic easily-releasable concrete test mould.

    摘要: A mold apparatus to form a ceramic (or glass) includes a first mold portion having a first coefficient of thermal expansion and a second mold portion having a second coefficient of thermal expansion. In some embodiments, the first mold portion and/or the second mold portion are substantially immiscible with the ceramic material, such as silicon oxide, at a temperature greater than 600° C. In some embodiments, the first coefficient of thermal expansion and the second coefficient of thermal expansion are substantially similar to that of the glass or ceramic material. In some embodiments, the first coefficient of thermal expansion is different from the second coefficient of thermal expansion. In some embodiments, the first mold portion and the second mold portion contain a surface coating and a passivation layer.

    摘要: In order to enable stable provision of an upward release tube-type ceramic filter used in a molten metal bath and having a side wall with a height of 300 mm or greater, this method for manufacturing a ceramic filter, which is an upward release tube-type integrally molded article for removing unwanted substances from molten metal, has: a step for kneading a mixture of an aggregate comprising ceramic particles, a prescribed binding agent, and water to prepare a base material; a step for integrally forming an upward release tube-type ceramic filter precursor from the prepared base material; step for drying the precursor; a step for providing a retainer for the dried precursor for supporting a side wall of the precursor; a step for subsequently sintering the precursor; and a step for removing the retainer after sintering.

    摘要: A method for preparation of a mold (10) intended to form a slab from a mixture of agglomerate comprising the steps of depositing over the mold surfaces a sheet (15) of PVA-based plastic material so as to form with it a surface for subsequent contact with the mixture introduced into the mold for forming the slab, whereby in at least some areas a layer (14) of a fluid agent containing PVA in a solution is interposed between the sheet (15) and the mold surfaces. A plant for carrying out the method and a method for production of a slab are also described.
