Problems solved by technology

However, the size of the existing split brick veneer is small, generally 240*60*10mm or smaller, and there are many joints after being placed on the wall, which is not suitable for the architectural style that pursues complete unity and large specifications; the split brick is constructed by wet paste , the combination with the wall is not too high, and it is easy to peel off due to the influence of the environment and climate. Therefore, for safety reasons, the state stipulates that wet-pa

Embodiment 1

[0028] Superplastic clay dry powder 25%, white mud dry powder 35%, feldspar powder 20%, 8-20 mesh coarse aggregate 20%; barium carbonate 0.5%, high-temperature pigment 3.0%, dry mix the above raw materials in a mixer for 30 minutes. Afterwards, it will be stale in the stale room for 2-3 days; then add 16% water to the stale material and mix it in a planetary mixer for 20 minutes; install a back-hanging extrusion die with a width of 300 mm and a thickness of 18 mm, at both ends of the die mouth at 3-4 mm Fix the fine steel wire so that it can be stretched straight when extruding; add material for vacuum extrusion, remove and recycle the wet material on the surface of the steel wire; dry the wet billet in a multi-layer drying kiln for 4 hours at a temperature of 160-180 °C; After drying, it is fired in a roller kiln at 1160°C for 4 hours; after sorting, cutting, and packaging, 18mm thick back-hanging brushed finish exterior wall dry-hanging ceramic panels are produced.

Embodiment 2

[0030] With reference to the method of Example 1, superplastic clay dry powder 35%, white clay dry powder 30%, feldspar powder 15%, 8-20 purpose coarse aggregate 20%; barium carbonate 0.5%, high-temperature colorant 4.0%, the above-mentioned raw materials are mixed in the blender Dry mix for 30 minutes. Afterwards, it will be stale in the stale room for 2-3 days; then add 16% water to the stale material and mix it in a planetary mixer for 20 minutes; install a side-hanging extrusion mold with a width of 600 mm and a thickness of 30 mm, and place the two ends at the die mouth at 3-4 mm Fix the thin steel wire so that it can be stretched straight when extruding; vacuum extrusion is added to remove and recycle the wet material on the surface of the steel wire; the wet billet is dried in a multi-layer drying kiln for 6 hours at a temperature of 160-180 °C; After drying, it is fired in a roller kiln at 1160°C for 6 hours; after sorting, cutting, and packaging, a 30 mm thick side-ha...

Abstract

The invention discloses a preparation method of a napping veneer exterior dry-hanging ceramic plate. The ingredients of the napping veneer exterior dry-hanging ceramic plate comprises 10-30% of high plastic clay dry powder, 20-40% of white clay dry powder, 10-30% of feldspar powder, 15-30% of coarse aggregate with the fineness of 8-20 meshes, and 0.2-7.0% of additives. According to the napping veneer exterior dry-hanging ceramic plate, a product capable of hanging in a dry-hanging manner such as back-hanging or side-hanging can be produced through a mold, is integrated with curtain wall keel, is already been widely applied in various middle-high buildings, and is high in safety reliability; as dry-hanging construction is adopted, no saltpetering problem of split bricks exists because of no cement contact; as a napping face ceramic plate is large in decorative face and is simple and efficient to mount, the labor cost and the construction time are reduced; as the plate is convenient to replace later through dry-hanging, unlike a split brick, a large-area brick does not need to be knocked off and paved again on the whole face, a broken brick is pulled out and a new brick is hung.

Description

technical field [0001] The invention relates to a method for preparing a dry-hanging ceramic plate, in particular to a method for preparing a dry-hanging ceramic plate with a brushed finish, and also relates to a product prepared by the method. Background technique [0002] Brushed finish is naturally applied to a variety of decorative materials because of its uneven surface and rough style, especially split bricks with brushed finish are widely used on exterior walls. Split bricks, also known as split bricks, are a type of ceramic wall and floor tiles. Generally, all kinds of clay or feldspar and other pottery raw materials are dry crushed and watered or wet ball milled to make wet mud, and then extruded by a vacuum screw extruder equipped with a hollow mold to become flat clay. The thin ribs connect the two bricks into one hollow body, which is then cut and dried, then fired, and then split into two pieces by hand or machine along the joint of the ribs, hence the name spl...
