Abstract

The invention discloses a preparation technology for a hollow brick. The technology comprises the steps that firstly, coal gangue and coal slag are crushed, and coal gangue particles with the particlesize of 2-3 mm and coal slag particles with the particle size of 3-5 mm are screened out respectively; then aging is carried out on the coal gangue and clay for 3-5 days, and then aging is independently carried out on the coal slag particles for 1-3 days; then a mixture and the coal slag are stirred according to the ratio of (1:0.1)-(1:0.2) to obtain a pug, the pug is added into a brick extrudingmachine for extrusion molding, and the formed hollow brick is naturally dried for 2-3 days; the temperature of a drying kiln is increased to 140-150 DEG C for drying for 4-6 hours; then the temperature of the drying kiln is increased to 170-180 DEG C for drying for 2-4 hours; then the temperature of the drying kiln is increased to 230-240 DEG C for drying for 2-3 hours; and the dried hollow brickis fired in a firing kiln to obtain a finished product of the hollow brick. According to the technology provided by the invention, through improving the existing preparation technology for the hollowbrick, great improvement on the strength of the hollow brick is realized.

Description

technical field [0001] The invention relates to a hollow brick manufacturing process. Background technique [0002] Because hollow bricks are light in weight and consume less raw materials, compared with the existing solid bricks, they can save a lot of land, soil and fuel for burning bricks, reduce the quality of transportation, reduce the labor intensity of brick making and bricklaying, speed up the construction progress, and reduce construction costs. Therefore, hollow bricks have gradually replaced solid bricks and become a commonly used building material in the construction industry in recent years; however, through the long-term use of hollow bricks, the defects of hollow bricks have also been gradually discovered. In order to make hollow bricks energy-saving building materials The advantages of light weight and light weight are more prominent, which greatly reduces the compressive strength of hollow bricks, which leads to the wall repaired with hollow bricks failing t...
