Problems solved by technology
[0004] In order to solve the above problems, the present invention provides a method for preparing a high-performance modified water-reducer of lignosulfonate, which can solve the problem that the traditional evaporation method is often static evaporation, and the liquid water-reducer does not flow and partially evaporates. The gas often adheres to the inner wall of the evaporating dish because it cannot be discharged in time, and then forms water droplets to re-enter the liquid water reducing agent, and the evaporation efficiency is slow.

The invention provides a preparation method of a lignosulfonate high-performance modified water reducing agent. The operation is finished by matching a chassis, an evaporation unit, a support frame, asealing cover, a stirring unit, a suction hood and an air pump, and the invention can solve the problems that a traditional evaporation mode is always static evaporation, a liquid water reducing agent does not flow, part of evaporated gas cannot be exhausted in time and is attached to the inner side wall of an evaporating dish, then water drops are formed and enter the liquid water reducing agentagain, and the evaporation efficiency is low.
Description
technical field [0001] The invention relates to the technical field of water reducer preparation, in particular to a method for preparing a lignosulfonate high-performance modified water reducer. Background technique [0002] In the past thirty years, concrete has developed rapidly and been widely used in my country, especially in some large cities and coastal areas in China, which has made the research on concrete admixtures more and more widely concerned. Water reducer is a commonly used concrete admixture, which is an anionic surfactant. On the one hand, the water reducer can be adsorbed on the surface of cement particles to make the particles show electrical properties, so that the cement particles repel each other due to the same charge, so that the cement The particles are dispersed and the excess water between the particles is released; on the other hand, the addition of the water reducing agent forms an adsorption film on the surface of the cement particles, which af...
