Method of preparing ganged brick by using aluminum scruff ash

Abstract

The invention discloses a method of preparing a ganged brick by using aluminum scruff ash, which comprises the following steps: (100) choosing the following components composed according to mass percent as materials: 60 to 65 percent of aluminum scruff ash, 15 to 20 percent of shale, 5 to 10 percent of quartz and 10 to 20 percent of additive; (200) uniformly mixing the materials composed according to the mass percent, performing ball milling on the materials by a ball mill after performing vibrational grinding on the materials to obtain powder; (300) carrying out pulp production on the powder, adding gelatin to pellet, then performing compression moulding by using a semi-dry pressing process to obtain a moulded blank; (400) drying the moulded blank in a drying tower; (500) putting the dried moulded blank in a sintering furnace to sinter to form the ganged brick. By adopting the method, the deformation of the ganged brick during the sintering process can be restrained; the strength of the ganged brick is improved; the ganged brick has the advantages of breathability and air permeability, good sound insulation function, good heat preservation function and frost resistance, moreover, the ganged brick is not easy to crack and layer.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of waste aluminum ash, in particular to a method for preparing clean-water bricks from waste aluminum ash. Background technique [0002] Clear water brick is a kind of high-quality wall masonry and decoration material. It has been widely used in some developed countries. Clear water brick not only has the advantages of energy saving, waste utilization, light weight, heat preservation and sound insulation of hollow bricks in the past, but also has other special features. advantage. It can be directly used as the outer surface of the wall without other decorations, thereby speeding up the construction and reducing the construction cost. [0003] At present, clear water bricks are mainly prepared from raw materials such as red mud and sludge. There are few studies on the use of waste aluminum ash to prepare clear water bricks, which is still in its infancy, and engineering research...

Problems solved by technology

[0003] At present, clear water bricks are mainly prepared from raw materials such as red mud and sludge. There are few studies on the use of waste aluminum ash to prepare clear water bricks, which is still in its infancy, and engineering research has not yet been completed.

However, raw materials such as red mud and sludge are prone to deformation during the sintering process, and the yield of finished products is low.
