Description
Technical field
The present invention relates to ceramic production device technical field, particularly relate to applicable hollow square brick and there is the vacuum extruding forming machine mould of circulation dampening system.
Background technology
Existing ceramic tile production method generally has two kinds, and one is that mould is dry-pressing formed, puts in mold cavity by dry mash, is pressed into base substrate by applying pressure, and another kind is wet-method extrusion molding, by pug by mould extrusion molding on vacuum-extruder.Existing vacuum-extruder, the friction of pug and shaping mold frame wall in extrusion, it is short-tempered that the surface that can make finished product adobe occurs, usual billet surface plucking is coarse, especially the edges and corners of adobe, it is easy to have and subside, the serious intensity affecting adobe and quality, follow-up sintering process easily causes crackle, makes the product qualified rate of ceramic tile reduce.
Square brick is a kind of sintering clay brick, and it is many employing plastic mud material molding in the way of vacuum extruding form.Namely first add water mixing one-tenth plastic mud material by raw material, again through vacuum-extruder extrusion molding.Because plasticity of slurry is required higher by vacuum extruding, therefore in pug, the consumption of plastic clay is usually less than 55%.Plastic clay is a kind of nonrenewable resources, and its exploitation and use are serious to environmental disruption.Therefore the quality that how can keep again vacuum extruding form when plastic clay consumption is relatively low is the emphasis that those skilled in the art pay close attention to.
Summary of the invention
It is an object of the invention to propose a kind of applicable hollow square brick and there is the vacuum extruding forming machine mould of circulation dampening system, reduce the abrasion between pug base substrate and mould, die life is long, the effective coarse phenomenon of plucking reducing adobe surface and hollow hole, improves the quality of square brick.It goes for the plastic clay mud material forming lower than 55%, and plastic clay consumption can be low to moderate 30%.
