Abstract

The invention discloses a production technology for a porous or hollow ceramic wall brick or ceramic building block. The production technology comprises the following concrete steps: crushing raw materials, stirring, preparing an adobe body, piling adobes, drying, turning over adobes, sintering, screening, preliminarily molding, glazing the sintered adobe body, sintering again, molding, packaging and the like. By employing the method, glaze is tightly combined with the adobe body, the glaze layer is not easy to fall off, the fineness of the finished-product brick or building block is prevented from being influenced because of a chemical reaction between gauge and glaze. Tiles, paint, sand and cement are saved, space for whitewashing and tile pasting is saved, labor cost is saved for two times, environment is protected, energy is saved, other surfaces except for a tangent plane of the adobe body are prevented from generating spots, the decorative effect of a finished product porous or hollow red brick or building block is improved, advantages of tile and the finished product porous or hollow red brick or building block are combined, and the produced porous or hollow ceramic wall brick or ceramic building block becomes a new-generation cheap and fine wall material.

Description

The production technique of a kind of porous or hollow porcelain wall brick, porcelain building block

Technical field

The invention belongs to building walling field, be specifically related to the production technique of a kind of porous or hollow porcelain wall brick, porcelain building block.

Background technology

In modern architecture construction, usually adopt common brick to build body of wall as wall brick, then rub sand with the hands at exterior surface of wall powder one deck and paste one deck facing tile with cement slurry again, or use sand-cement slurry to whitewash or brush one coating at exterior surface of wall.Large-area like this laying facing tile or whitewash or last layer coating, not only increases material and cost of labor, does not save space, and extend the architecture construction duration.

But also have in prior art at wall brick outer surface glaze layer, reach the object exempting from tiling, but this coating method, and glaze layer is easy to come off from wall brick, affects decorative effect and time limit of service.

In addition, existing common brick or building block production technique, easily produce spot in sintering procedure, if hide not fall, will affect the attractive in appearance of product.

Summary of the invention

For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of environmental protection, material saving, economize secondary artificial, save space, the production technique of lightweight porous or hollow porcelain wall brick, porcelain building block.

This inventiontechnical scheme be: the production technique of a kind of porous or hollow porcelain wall brick, porcelain building block, comprises following concrete steps:

(1) raw material pulverizing, stirring: red shale, coal gangue are crushed to grain diameter≤2.5mm respectively, wherein grain diameter≤the 1mm of more than 70%, then by red shale: coal gangue is that the weight ratio of 3.5-4.5:1 adds water and stirs, make base substrate material, the weight ratio of its Raw and water is 1:0.1;

(2) native body preparation: sent in twin-stage hard plastic vacuum-extruder through conveying belt by base substrate material and be squeezed into base bar, wherein extrusion pressure is 4.0Mpa, and shaping water ratio is 13%-16%; Then base bar is sent in brick cutting machine or block building machine and be cut into sun-dried mud brick body;

(3) code base: to be got on the right track car by automatically grabbing base machine code by sun-dried mud brick body, base substrate tangent plane is positioned at two sides;

(4) dry: by rail car, the base substrate on car is sent into oven dry kiln dry, bake out temperature is 80-150 DEG C, and the humidity after oven dry is 9.5%-10.5%;

(5) turn over base: turned out by the base substrate of oven dry, the contact surface between base substrate and base substrate is transferred on the tangent plane of base substrate;

(6) sintering briquette: sent in tunnel brick kiln by rail car by the base substrate after turn-over and burn, sintering temperature is 1000-1150 DEG C, and the time is 20-25h;

(7) screening, pre-profiling: pick out flawless from burned base, carry out bevelling, chamfering is shaping;

(8) base substrate glazing: the base substrate of pre-profiling is automatically sprayed in advance deployed glaze twice according to customer requirement in 1 or 2 or 3 or 4 faces except tangent plane, and coplanar can not spray different colours or pattern;

(9) again burn: sent in ceramic roller kiln by the base substrate after glazing and again burn, the material according to glaze determines sintering temperature and sintering time, and general sintering temperature is 800-1200 DEG C, time 6-12h, obtains finished product porous or hollow porcelain wall brick, porcelain building block;

(10) shaping packing.

Compared with prior art, advantage of the present invention is: 1, by the ratio collocation that red shale, coal gangue are appropriate, microcosmic biochemical reaction occurs between the two, promote the activation of raw material, improve the intensity of common brick or the building block of preparing; 2, reglazed by first sintering briquette body, reburn, glaze is combined with base substrate closely, glaze layer difficult drop-off, and avoids the smooth finish affecting finished bricks or building block because of coal gangue and glaze react with, improves quality and the aesthetics of finished bricks or building block; 3, by firing glaze layer in porous or hollow common brick or building block base substrate, economizing ceramic tile, coating and sand and cement, also saving 2 labour costs, environmental protection and energy saving; 4, between oven dry with sintering briquette, turn over base, effectively avoid base substrate generation spot in other face except tangent plane except, improve the decorative effect of finished product porous or hollow common brick, building block; 5, the space whitewashed with tiling is saved; 6, the architecture construction duration is shortened; 7, the overall weight of buildings is alleviated; 8, safer because not pasting wall tile; 9, the porcelain wall brick produced by the present invention or porcelain building block, higher than existing porous or hollow common brick, block strength, Functionality, quality and appealing design, lightweight, combine the advantage of ceramic tile and porous or hollow common brick, stripping and slicing, become the materials for wall that a new generation is inexpensive.
