Preparation method of cement water reducing agent

Abstract

The invention relates to a preparation method of a cement water reducing agent. The preparation method of the cement water reducing agent adopts the following preparation equipment of the cement water reducing agent. The preparation equipment of the cement water reducing agent comprises a fixed frame, preparation devices, a connecting bottom plate and an intermittent material receiving device. The lower end face of the fixed frame is fixed to the ground, the preparation devices are connected to the upper portion of the fixed frame in a front-back symmetry mode, the intermittent material receiving device is arranged below the preparation devices and installed on the upper end face of the connecting bottom plate, and the lower end face of the connecting bottom plate is fixedly arranged on the ground. By means of the preparation method of the cement water reducing agent, crushing frames are arranged in an up-and-down staggered mode, so that it is guaranteed that a blocky water reducing agent can be fully crushed, and the blocky water reducing agent which is not crushed is prevented from directly falling down; and guide grooves are uniformly formed in the outer wall of a guide block, so that the situation that a large number of granular water reducing agents are accumulated in discharging grooves, and the grinding effect is affected is prevented.

Description

technical field [0001] The invention relates to the field of cement water reducer, in particular to a preparation method of cement water reducer. Background technique [0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged; most of them belong to anionic surfactants, including lignosulfonate and naphthalene sulfonate formaldehyde polymers ; After being added to the concrete mixture, it has a dispersing effect on the cement particles, which can improve its workability, reduce the unit water consumption, and improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement; Enhancement ability, divided into ordinary water reducer, high efficiency water reducer and high performance water reducer, and respectively divided into early strength type, standard type and retarded type. [0003] Since the water reducer is extracted through the cooking process...

AI Technical Summary

Problems solved by technology

[0004] (1) When crushing block water reducers, due to crushing multiple block water reducers at the same time, unbroken block water reducers may fall directly, which will affect the later grinding ;

[0005] (2) In the process of grinding the granular water reducing agent, if the falling position of the granular water reducing agent is not uniform, there will be less granular water reducing agent in some places, and a large amount of granular water reducing agent will accumulate in some places. Water agent, so the uniformity of granular water reducer grinding cannot be guaranteed
