Embodiment Construction

[0012] As shown in accompanying drawing 1, it includes the following steps: feeding and stirring, pouring, static stop curing, overturning and demoulding, longitudinal cutting, cross cutting, pre-curing, autoclaving, heat preservation, and stacking. In the stop curing step, a static stop curing kiln made of thermal insulation materials can be installed. The poured concrete slurry enters the static stop curing kiln, and the temperature in the kiln is controlled by radiator cooling and ventilation (40-60°C) and humidity (70-95%), to promote the hardening of the air-entrained concrete slurry, to prevent cracks on the surface of the green body before the subsequent cross-cutting and longitudinal cutting steps; the pre-curing step of cutting is realized by the pre-curing kiln. In the pre-curing step, a pre-curing kiln made of thermal insulation materials can be set. The kiln body is kept sealed and can withstand a micro-pressure below 0.04Mpa. A nozzle is installed on the kiln body....

Abstract

The invention relates to a production technology of architectural air entraining concrete, which includes some steps as follows: feeding, stirring, pouring, still solidification, inverting demould, longitudinal cutting, transverse cutting, procuring, autoclaving, insulating heat, dividing piles and so on. On the mentioned still solidification and procuring and insulating heat steps, the still curing kiln and procuring kiln and cooling kiln is apart installed which are all made up of heat insulating materials, and the temperature and humidity condition needed by the material reaction will be supplied, the temperature and humidity difference between environment and product in production process will be controlled so as to improve the product property and prevent the product from broken and damage due to the attractive force formed by excessive temperature and humidity difference.

Description

Technical field: [0001] The invention relates to the technical field of processing methods of building materials, in particular to a production process of autoclaved aerated concrete. Background technique: [0002] In recent years, air-entrained concrete has gradually become a widely used building material. At present, there are many manufacturing methods for aerated concrete, but the ingredients and proportions are basically the same, and most of them include feeding and stirring, pouring, static curing, flipping demoulding, cross-cutting, longitudinal cutting, stacking, and mold closing. step. However, in the production process, the static stop solidification step is to directly put the poured slurry in the air to let it harden naturally, the speed is relatively slow, and the surface is prone to cracks in the subsequent cutting process; The final billet directly enters the autoclave set in the autoclave step. Because the temperature in the autoclave is relatively high, t...
