Static press-forming method of gypsum steam brick adobe

Abstract

The invention discloses a static press-forming method of a gypsum steam brick adobe, relating to a production method of a gypsum brick adobe. Dihydrate ardealite, slag, hydraulic cementing material and liquid phase adhesive are used as raw materials. According to the method, the raw materials are proportionally mixed and sent into a mould of a forming machine. When the forming machine is kept in a static condition, the ardealite mixed material is pressed by high pressure to obtain a formed adobe. The application of the method shows that the shapes and the size of the adobe and a finished brick conform to the standards, the volume weight of the finished brick can be thoroughly controlled to be 800-1500 kg/m<3>, and the finished product ratio is over 95 percent. The method not only reduces the energy consumption but also improves the adobe qualification rate and the production efficiency. The method requires simple technical apparatuses, has low production cost, can select corresponding technical apparatus models according to the production scale or the storage amount of the ardealite, and is suitable for enterprises producing gypsum steam bricks.

Description

technical field [0001] The present invention relates to a composition containing an inorganic binder, and also relates to a production method of a pressure-formed product, in particular to a production method of a gypsum brick adobe. Background technique [0002] Many technologies have been developed using industrial waste slag to make bricks, such as Chinese Patent Application No. 03117792.1 "Bricks without Burning Waste and Its Manufacturing Method", No. 200510103135.1 "Manufacturing Method of Electric Gypsum Bricks", No. 200610051112.5 "High-strength Water-Resistant Gypsum Bricks and Their Preparation Methods" "Wait. These methods generally use one-shot pre-vibration forming to produce bricks. One-time pre-vibration molding to produce bricks has the following defects: (1) The material cannot be tapped well during the forming process, and the compactness of the bricks is low, which is reflected in the low weight of the bricks; (2) The height of the bricks is unstable, res...

Problems solved by technology

One-time pre-vibration molding production of adobe has the following defects: (1) The material cannot be well vibrated during the forming process, and the compactness of the adobe is low, which is manifested in the low weight of the adobe; (2) The height of the adobe is unstable, resulting in gypsum bricks. The deviation of geometric size is large; (3) The air in the adobe is not completely removed, resulting in too many cracks in the adobe, the qualified rate of the adobe is low, and the production efficiency is low

However, the power consumed by the two pre-vibration molding is more, and the labor productivity is not high enough.
