Preparation method of retarding superplasticizer

Abstract

The invention relates to a preparation method of a retarding superplasticizer, which mainly comprises the following steps of: aluminum chloride preparation, asbestos wool preparation, mixing treatment and other processes. Asbestos wool crushing equipment used in the method comprises a bottom plate, a charging device, a lifting device, a drop hammer device and a discharging device. The method can solve the following problems existing in existing asbestos wool crushing: a, when asbestos wool is crushed in a traditional mode, most of the asbestos wool is manually beaten and crushed by using a crushing tool, and the working environment of workers and the body health of the workers are influenced due to the fact that the asbestos wool is relatively light in weight and easy to fly; and b, when asbestos wool is crushed at present, the asbestos wool cannot be comprehensively crushed, so that the crushing of the asbestos wool is not uniform, and the crushing quality of the asbestos wool is influenced.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for preparing a slow-setting high-efficiency water reducer. Background technique [0002] At present, commercial concrete and pumping construction technology are mostly used for concrete. Commodity concrete is also called centralized mixing concrete, that is, the concrete mixed in the traditional on-site construction site is gathered together to set up a mixing station, and the concrete mixed by it is transported to the construction site by a mixer truck, and then transported to the building by a pump truck through a pump pipe. At the construction level, if there is no retarding treatment, especially in high temperature weather in summer, the moisture will evaporate quickly, and the concrete will harden and cannot be used even before it is transported to the construction site, so it is necessary to add a retarder when mixing the concrete In order to delay the ...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the crushing of existing asbestos velvet. a. When the traditional asbestos velvet is crushed, most of them are manually beaten and crushed with crushing tools. Because the quality of asbestos velvet is relatively light, it is easy to fly and affects the working environment of the staff. , affect the health of the staff; b, when the existing asbestos wool is crushed, the asbestos wool cannot be crushed comprehensively, which makes the crushing of the asbestos wool uneven and affects the crushing quality of the asbestos wool
