Description

High synthetic device who protects and mould polycarboxylate water reducing agent

Technical Field

The utility model relates to the field of synthesis of polycarboxylate superplasticizers, in particular to a synthesis device of a polycarboxylate superplasticizer with high plastic retention.

Background

The polycarboxylate water reducing agent is a latest generation high-performance water reducing agent after common water reducing agents such as lignin, calcium lignosulfonate and the like, and sulfamate, aliphatic and melamine high-efficiency water reducing agents. The polycarboxylate superplasticizer has the advantages of high water reducing rate, low mixing amount, flexible molecular structure and the like, and can have different properties by adjusting the density of main chain carboxyl, the length of a side chain and grafting different functional groups.

A polycarboxylic acid water reducing agent (Polycarboxylate Superplasticizer) is a high-performance water reducing agent and is a cement dispersing agent in cement concrete application. The method is widely applied to projects such as highways, bridges, dams, tunnels, high-rise buildings and the like.

The polycarboxylic acid high-efficiency water reducing agent products can be divided into two main types according to the difference of the main chain structure: the polyether with different side chain lengths is grafted by taking acrylic acid or methacrylic acid as a main chain. The other type is polyether with different side chain lengths grafted by maleic anhydride as a main chain. Based on the water reducer, a series of high-performance water reducer products with different characteristics are derived.

Before the appearance of the polycarboxylic acid additive, there are lignin sulfonate type additives, naphthalene series sulfonate formaldehyde condensates, melamine formaldehyde condensates, acetone sulfonate formaldehyde condensates, sulfamate formaldehyde condensates, and the like. The polycarboxylic acid water reducing agent is successfully developed in Japan in the beginning of the 80 s in the 20 th century. The new generation of polycarboxylic acid high-efficiency water reducing agent overcomes the defects of the traditional water reducing agent, and has the outstanding advantages of low mixing amount, good slump keeping performance, low concrete shrinkage, strong adjustability on molecular structure, high potential of high performance, no use of formaldehyde in the production process and the like.

In the synthesis production of the high-plasticity-maintaining polycarboxylate water reducer, the reaction raw materials need to be controlled in temperature to generate the high-plasticity-maintaining polycarboxylate water reducer with high quality, but the existing reaction kettle cannot directly control the temperature, and a temperature control device is used for controlling the temperature independently after mixing, so that the production is inconvenient.
