Method for manufacturing diatomite porous thermal insulation brick

Abstract

The invention relates to a manufacturing method of diatomite porous brick. The weight percentages of raw materials of the brick are as follows: diatomite 55-75 percent, fly ash 20-30 percent and wood dust 5-15 percent. The manufacturing method comprises the steps of compounding, melting, extrusion molding, brick blank drying, brick blank calcination, and final production inspection and preservation. The inventive brick utilizes diatomite as main ingredient and fly ash and wood dust as adjuvant, has a plurality of uniformly-distributed round or square hole on the front surface, and has hollow structure instead of solid structure of the prior wall brick. Therefore, the inventive brick has the advantages of higher strength, good fire-proof and heat-insulating effects, less waste of diatomite resource and low cost. The diatomite porous heat-insulating brick is, so far, the better light-weight wall material with effects of both heat insulation and heat preservation.

Description

1. Technical field: [0001] The invention relates to a building wall brick, in particular to a method for manufacturing a diatomite porous heat preservation brick with diatomite as the main raw material and endowed with dual functions of wall material and heat insulation. 2. Background technology: [0002] At present, the diatomite insulation bricks used in the heat insulation of high temperature equipment and kilns in the industrial field have low strength and cannot meet the strength requirements of the wall; the surface is loose to be regular and must be ground and shaped; the main raw material Use better diatomite, and it must be dried and crushed into powder before it can be produced. Therefore, the cost of raw materials is high, and there are many problems such as large dust and environmental pollution. It is not suitable for energy-saving building wall materials with large quantities and wide areas. . 3. Contents of the invention: [0003] Aiming at overcoming the p...
