Method for manufacturing foam ceramic plates by using ceramic tile polishing waste residues

Abstract

The invention discloses a method for manufacturing foam ceramic plates by using ceramic tile polishing waste residues. The method comprises the following steps: preparing 50-80% of polishing waste residues, 10-25% of shale, 10-25% of feldspar and 0.5-3% of a foaming agent according to raw materials ratios, carrying out ball milling, stirring, preparing powder by spraying, sieving, stirring, pelleting, carrying out extrusion molding, drying and sintering, wherein in an extrusion molding step, at least two rows of mud fending parts which are uniformly distributed along the periphery of an extrusion cylinder and are transversely overhung in the extrusion cylinder are arranged on the wall of the extrusion cylinder of an extrusion machine, and each row of mud fending parts are distributed along the axial direction of the extrusion cylinder at intervals; and the inner walls of the upper side and the lower side of an extrusion mold opening of the extrusion machine are arranged to be protruded forwards in an arc-shaped manner relative to the inner walls of the left side and the right side. According to a conventional ceramic plate manufacturing technology, the proportion of plastic raw materials reaches up to 60-80%. According to the ceramic plate manufacturing method disclosed by the invention, the doping amount of the polishing waste residues reaches up to 50-80%, that is, the proportion of a lean raw material is far higher than that of the plastic raw material mainly because of the difference of technical formulas and the unique design of the extrusion machine.

Description

technical field [0001] The invention relates to the technical field of production methods of ceramic plates. Background technique [0002] The industrial structure of the modern building materials industry is changing from traditional high-energy-consuming products to emerging low-energy-consuming products. A new type of green and environmentally friendly building material product - ceramic panels is also born under this background. Ceramic panels have the functions of sound insulation, noise reduction, heat insulation and heat preservation, and ceramic panel products also have the advantages of green environmental protection, no radiation, rich color types, and mild tones. Ceramic plates are generally formed by extrusion, the mixed mud is injected into the extrusion cylinder, the mud is extruded from the die by a screw, and it is foamed and fired after drying. During the extrusion process, the mud material will move in the circumferential direction with the screw, and ther...

Problems solved by technology

However, in the existing production of foamed ceramic plates, the rate of polishing slag mixed in is low, and the polishing slag cannot be fully utilized.
