Method for preventing deterioration of Superplasticizer Asam Polikarboksilat
Superplasticizer Asam Polikarboksilat is a kind of cement dispersant used in cement concrete, which is widely used in tunnels, highways, bridges and other construction projects. However, it is easy to decay and deteriorate in a high temperature environment, resulting in no effect. Here is the method of pre-corrosion deterioration and deterioration.
1. Pay attention to the storage environment of Polycarboxylic Acid Superplasticizer: try to store the Superplasticizer Asam Polikarboksilat in a cool, ventilated place without direct sunlight.
2. Reduce the use of preservatives such as formaldehyde and nitrite. It is understood that some foreign manufacturers currently use formaldehyde, sodium benzoate and strong oxidizing nitrite for corrosion protection.
3. Reasonably estimate the amount of Superplasticizer Asam Polikarboksilat used in the project: In some engineering projects, due to factors such as project progress, weather and environment, the use speed of polycarboxylic acid water-reducing agent is often not easy to control. In some projects, the Polycarboxylic Acid Superplasticizer  has been placed on the construction site for more than 3 months or even longer, and decay and deterioration occur from time to time.
4. Adding preservatives during the compounding process: compounding a part of the preservatives during the production process of the Superplasticizer Asam Polikarboksilat can effectively improve the deterioration of thePolycarboxylic Acid Superplasticizer.

5. Selection of sodium gluconate retarder: There are many sodium gluconate manufacturers on the market, and manufacturers with strict production control systems can effectively control the residual amount of glucose and Aspergillus niger during the production process, and reduce the water reduction of Superplasticizer Asam Polikarboksilat spoilage.
