A kind of preparation method of cement water reducer

Abstract

The invention relates to a method for preparing a cement water reducer. The cement water reducer preparation method adopts the following cement water reducer preparation equipment. The cement water reducer preparation equipment includes a fixed frame, a preparation device, a connecting bottom plate and an intermittent material receiving device; The lower end surface of the fixed frame is fixed on the ground, and the upper part of the fixed frame is symmetrically connected with the preparation device, and an intermittent material receiving device is arranged under the preparation device, and the intermittent material receiving device is installed on the upper end surface of the connection base plate, and the lower end surface of the connection base plate Fixedly installed on the ground, the invention ensures that the block water reducer can be fully broken through the staggered arrangement of crushing racks up and down, and prevents the unbroken block water reducer from falling directly; The trough prevents a large amount of granular water reducer from accumulating in the trough, thereby affecting the grinding effect.

Description

technical field [0001] The invention relates to the field of cement water reducing agent, in particular to a preparation method of cement water reducing agent. Background technique [0002] Water reducing agent is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged; most of them are anionic surfactants, including lignosulfonate, naphthalenesulfonate formaldehyde polymer ; After adding 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; The enhancement ability is divided into ordinary superplasticizer, high-efficiency superplasticizer and high-performance superplasticizer, and is further divided into early strength type, standard type and retardation type. [0003] Since the water-reducing agent is extracted by...

AI Technical Summary

Problems solved by technology

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

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