Description
Technical field
The present invention relates to ceramic field, particularly, the present invention relates to light non-fired architectural pottery field.
Background technology
Architectural pottery refers to for building facing or the ceramic as building slab, can be used for Production Example as floor, ceramic tile, wall brick, pottery, mosaic etc., it be by other raw material of various raw mineral materials and interpolation etc. by certain proportioning through pulverizing, mixing, shaping or glazing and sintering stupalith.Architectural pottery is except possessing the traditional performances such as shock resistance, water-repellancy, didirtresistance, in recent years also to property future developments such as germ resistance, "dead", noise immunities, and architectural pottery is handsome in appearance, of a great variety, novel appearance, decorative pattern variation, thus in the widespread use of building decoration field.
Construction ceramic industry is the important component part of building materials industry, although China's ceramics has long history, construction ceramic industry after reform and opening-up just true development get up.Compared with traditional ceramics, architectural pottery, except inheriting tradition ceramic characteristics, also shows many new performances.But, architectural pottery is the same with other building materials, all the time fail to change " three is high " situation of high pollution (when firing discharge the atmosphere pollution such as great amount of carbon dioxide, sulfurous gas do not meet national industrial policies), high energy consumption (pottery needs more than 1250 DEG C and forms by a firing, and belongs to high energy-consuming industry), maximum discharge.China's building materials industry energy consumption total amount 1.95 hundred million tons in 2007, becomes the major power consumer being only second to electric power and metallurgy industry, and energy-saving and cost-reducing the situation is tense.The industrial development pattern of this rough growth type will make China's energy, resources and environment can't bear the heavy load.
Baking-free ceramic is one of the terms of settlement solving ceramic industry high pollution, high energy consumption problem.A kind of typical baking-free ceramic is solidifying porcelain, the natural mineral matter synthesized by multiple inanimate matter and other inanimate matter weighting material are made, its one-tenth porcelain principle is that the gelling initiator in material prescription causes jelling agent at normal temperatures, then by a series of chemical reaction, gel is crosslinking in inorganic filler mutually, forms pottery through spontaneous curing.The prolongation of intensity set time of pottery and strengthening, finally reaches firmness degree.
