Sintering method of light sintered shale brick with rectangular openings

Abstract

The invention discloses a sintering method of a light sintered shale brick with rectangular openings, wherein the method comprises the following steps: drying and preheating a green shale brick so as to expel heat in the green shale brick; heating the green shale brick until the green shale brick gets burned when the ignition point of sawdust in the green shale brick is reached, so that micro-pores which are uniformly distributed are formed in the green shale brick; sintering the green shale brick; and cooling the sintered green shale brick to normal temperature, so that the light sintered shale brick with rectangular openings is prepared. The light sintered shale brick with rectangular openings sintered by adopting the method disclosed by the invention not only has the advantages of being good in heat insulation and low in volume weight, having strength meeting the requirement of a partition wall and the like as an aerated concrete brick in non-sintered wall materials, but also has the advantages of being good in thermal stability, relatively low in the rate of thermal expansion, good in weather resistance, low in water absorption, good in heat insulation and sound insulation effects, free from wall cracking and the like as a high-temperature sintered solid clay brick in sintered wall materials.

Description

technical field [0001] The invention relates to a novel wall material shale brick, in particular to a sintering method of a rectangular-hole lightweight sintered shale brick. Background technique [0002] At present, the existing new wall materials are mainly developed in the direction of environmental protection, energy saving, and green building materials, mainly including blocks, bricks, and boards. Existing new wall materials currently on the market include aerated concrete blocks, concrete perforated bricks, ordinary concrete small hollow blocks, and new brick wall panels. [0003] Among them, the air-entrained concrete block has high air attack rate and high water absorption, and its surface is easy to generate powder, which cannot be well bonded with mortar, and its surface strength is low, and it is prone to missing corners and cracks, which increases the difficulty of transportation, etc. shortcoming. [0004] Ordinary concrete small hollow blocks also have disadv...
