Environment-friendly dry-mixed mortar and preparation method thereof
The invention relates to the technical field of preparation of dry-mixed mortar, in particular to environment-friendly dry-mixed mortar and a preparation method thereof. The invention relates to a preparation method of environment-friendly dry-mixed mortar. The preparation method specifically comprises the following steps: preparing recycled aggregate from construction waste; fine aggregate is screened out; mixing the fine aggregate, cement, starch ether and hydroxypropyl methyl cellulose; freezing and melting to obtain uniform fine aggregate; dehydrating and crushing banana stalks, coconut shells and coconut skins; and third-stage mixing. During three-stage mixing, desulfurized fly ash is added into a second-stage auxiliary material storage box, negative pressure is generated in a material mixing barrel of a three-stage mixing device through an air extractor, and a pressure sensor controls opening and closing of the second-stage auxiliary material storage box, so that the desulfurized fly ash and air are sucked into the material mixing barrel together for centrifugal mixing and stirring; the effect of uniformly mixing the materials in the three-stage mixing device is achieved.
本发明涉及干粉砂浆制备技术领域，具体涉及一种环保型干粉砂浆及其制备方法。一种环保型干粉砂浆的制备方法，具体包括以下步骤：运用建筑垃圾制备再生骨料；筛选出细集料；将细集料、水泥、淀粉醚和羟丙基甲基纤维素混合；冷冻熔融得到均匀细粒集料；脱水破碎香蕉茎秆、椰壳和椰皮；三级混合。本发明在三级混合时将脱硫灰加入二级辅料储存箱内，通过抽气装置在三级混合装置的混料筒内产生负压，并压力传感器控制二级辅料储存箱开关，使得脱硫灰与空气一起被吸入混料筒内进行离心混合搅拌，达到了将三级混合装置内的物料混合均匀的效果。
