Process characteristics of powder polycarboxylic acid water reducer

Polycarboxylic acid series high-performance water reducing agent is a new generation of high-performance water reducing agent appearing at home and abroad in recent years. Compared with naphthalene series and other traditional superplasticizers, polycarboxylic acid series high-performance superplasticizers have many unique technical performance advantages:

(1) Low dosage, high water reduction rate;

(2) Good retention of the fluidity of concrete mixture;

(3) Good compatibility with cement;

(4) The prepared concrete has small shrinkage, which is conducive to improving the volume stability and durability of concrete;

(5) It is environment-friendly and pollution-free during production and use, and belongs to green additive. It is precisely because of the above performance advantages that Polycarboxylate Superplasticizer Powder has attracted extensive attention in the domestic engineering field in recent years, and this new type of water reducer has been widely used in many important projects. It can be predicted that due to the above many unique performance advantages, polycarboxylic acid series high-performance water reducer will quickly become the mainstream product in the water reducer market.

Because most of polycarboxylate ether superplasticizer are in liquid state, the pulverizing process is complex and the production process is unsafe. Therefore, liquid products are mostly sold on the market. In recent years, due to the improvement of technology and the improvement of milling process, polycarboxylic acid series high-performance water reducing agent in powder state has also become more common.
