Production technology of dry-mixed mortar

Abstract

The invention provides a production technology of dry-mixed mortar. The production technology comprises the steps of firstly, preparing materials, wherein natural sand is replaced with recycled aggregate; secondly, blending the materials, wherein dried powder materials are weighed, and the required dry powder materials in a certain proportion are obtained; thirdly, blending additives, wherein a thickening agent and other additives are weighed and prepared according to the proportion; fourthly, lifting, wherein the blended raw materials are lifted to a raw material tank; and fifthly, mixing, wherein the weighed raw materials fall into a stirrer at the lower position to be evenly mixed. According to the production technology of the dry-mixed mortar, the natural sand raw material is replaced with the recycled aggregate, the high mixing ratio is achieved, the raw materials are more environment-friendly, the quality of products is high, the products are mixed and can be used immediately, multiple types of the products can be provided, the mixing uniformity is high, and production efficiency is high; systems are controlled by a computer to operate in the production process, workloads are reduced, the material blending precision is high, and use is convenient; and closed production is adopted, and the site is clean and free of pollution.

Description

technical field [0001] The invention relates to a production process of building materials, in particular to a production process of dry powder mortar. Background technique [0002] For construction projects, it is usually necessary to make cement mortar on a special site, and then transport it to the construction site. Since the cement mortar is easy to solidify, the transport vehicle must be equipped with a mixing device, which increases the cost. The dry powder mortar is to mix powdery sand, cement and other additives. When using it, you only need to add water to the mixture and stir it. standardization. However, a large amount of natural sand is needed in the production process of dry powder mortar. The overexploitation of natural sand has caused the resource environment of our country to deteriorate. At present, there is still a shortage of dry powder mortar production technology with low pollution and high performance. [0003] Replacing sand with recycled aggregate ...
