Embodiment Construction
[0016] Combine below Figure 1 to Figure 5 The present invention is further described:
[0017] This embodiment is a mold that can be used to fire lightweight closed-cell foamed ceramics (in a broad sense, including foamed glass and foamed ceramics fired at various temperatures). 3 and the embedded cover plate 4 form an inner cavity of the mold, and a refractory material tube or a ceramic tube is built in the inner cavity to promote heat transfer during the firing process of the foamed ceramic.
[0018] The cross-sectional structure diagram of the present embodiment through the central axis of the built-in pipe is as follows: figure 1 shown. The mold includes a bottom plate 1 , a built-in pipe 2 , a protective plate 3 and a built-in cover plate 4 . The bottom plate 1, the enclosure plate 3 and the built-in cover plate 4 enclose the cavity of the mold, and the built-in pipe 2 is placed in the cavity of the mold. Wherein: the base plate 1 and the enclosure plate 3 are movabl...

Abstract
The invention relates to a mould used for making light closed-cell foamed ceramics, which belongs to the technical field of construction materials. The mould comprises a bottom plate, a maintenance panel, a built-in cover board and a built-in pipe. The well-distributed built-in pipes are inserted into the bottom plate and the built-in cover board made of refractory material is nested into the pipe. A pore space in which the built-in pipe is vertically arranged is formed by the bottom plate, the built-in pipe and the maintenance panel. Compounding material is pressed compact according to the structure and the shape of an internal chamber prior to loading. The compounding material is filled into the mould during the loading to ensure a close-grained filling effect. With the completion of the loading, an upper cover board is placed on the compounding material. As the built-in pipe is arranged in the mould, heat transmission during the process of sintering can be enhanced, the time of sintering and annealing can be shortened and the cycle and the energy consumption of the sintering can be reduced. The mould can be used for sintering zeolite-diatomite foamed ceramics, wasted ceramics clay foamed ceramics, fly ash-wasted glass foamed ceramics and coal gangue-glass-caustic sludge foamed ceramics, etc.
Description
technical field [0001] The invention relates to a mold for manufacturing lightweight closed-cell foam ceramics, belonging to the technical field of building materials. Background technique [0002] Lightweight closed-cell foamed ceramics, in a broad sense, include various lightweight closed-cell foamed inorganic materials fired at different temperatures and with different glass phase contents. Lightweight closed-cell foam ceramics have the characteristics of low water absorption, good chemical stability, light weight, and thermal insulation, and are widely used in thermal insulation materials. With the deepening of earthquake relief work, there is also a demand for floating materials with a certain strength, and closed-cell lightweight foam ceramics can meet this demand. In the manufacturing process of foamed ceramic materials, the increase in the volume of foam blocks has great significance for both thermal insulation materials and water-floating materials. However, in th...
