Method for producing aerated concrete blocks by lime wet pulping
The invention provides a method for producing aerated concrete blocks by lime wet pulping. The method comprises the following steps of adding quartz sand and quicklime into a ball mill, adding water,mixing, and carrying out ball milling to prepare slurry at 38-40 DEG C; pumping slurry into a burdening stirrer, adding Portland cement, uniformly stirring, adding aluminum powder, a polycarboxylate superplasticizer and an oxidized paraffin soap bubble stabilizer, uniformly stirring and mixing components, discharging the slurry into a mold, and carrying out injection molding; and after injection molding, feeding the mixture and the mold into a constant-temperature chamber together, and obtaining the concrete block after gas generation, thickening and hardening. By adopting the method, in the thickening stage after gas generation is completed, the uniformly distributed calcium hydrate system reduces the existence of intermediate water and increases adsorbed water, so that the slurry thickening speed is increased, the pouring stability is improved, the thickening time is shortened, and the production efficiency is improved.
本发明提供一种石灰湿法制浆生产加气混凝土砌块的方法，将石英砂和生石灰加入球磨机中，加水混和后球磨，制成温度为38～40℃的料浆；料浆抽入配料搅拌机，加入硅酸盐水泥，搅拌均匀后加入铝粉、聚羧酸减水剂和氧化石蜡皂气泡稳定剂，待各组分搅拌混合均匀后，将料浆卸入模具内注模；注模后连同模具一起送入恒温室，经发气、稠化、硬化后得到混凝土砌块。采用本发明的技术方案在发气完成后的稠化阶段，均匀分布的水化钙体系减少了中间水的存在，增加了吸附水，从而提高了料浆稠化速度，提高了浇注稳定性，缩短了稠化时间，提高了生产效率。
