Abstract

The invention relates to the technical field of concrete admixtures, and particularly discloses a polycarboxylate-type water reducer and amino-type water reducer composite production system which comprises metering tanks and a reaction kettle, the metering tanks comprise a polycarboxylate-type water reducer metering tank, an amino-type water reducer metering tank and an ingredient metering tank, all the metering tanks are connected with the reaction kettle, a stirrer is arranged in the reaction kettle, and the reaction kettle is connected with the polycarboxylate-type water reducer metering tank and the amino-type water reducer metering tank. The stirrer extends into the bottom of the reaction kettle, the reaction kettle is fixedly connected with a mounting seat, the mounting seat is rotatably connected with a plurality of rotating rollers, the plurality of rotating rollers are positioned in the circumferential direction of the stirrer, and the rotating rollers abut against the stirrer. The scheme is used for solving the problem of high mud-containing sensitivity of a polycarboxylic acid water reducer in the prior art.

Description

technical field [0001] The invention relates to the technical field of concrete admixtures, in particular to a compound production system of a polycarboxylate water reducer and an amino water reducer. Background technique [0002] Water reducer is a very important admixture in concrete admixtures. The classification of water reducer mainly includes lignin water reducer, naphthalene water reducer, melamine high efficiency water reducer, amino water reducer and poly Carboxylic acid-based water reducers, etc. Among them, polycarboxylic acid-based water-reducers have high water-reducing rate, low shrinkage, high strength, low bleeding and low slump loss, etc. , slump retention and other properties are higher than other water reducers; in the selection of water reducers, it needs to be determined according to the characteristics of other materials for preparing concrete, such as sand, stone and cement, but the existing polycarboxylate Although acid-based superplasticizers have g...
