Overview of Gypsum Defoamer

The main function of gypsum defoamer: gypsum defoamer is a defoamer specially designed for gypsum. The main composition is modified polyether, esterified and high-carbon alcohols, refined by special technology.

Advantages of Gypsum Defoamer

No oil bleaching, no suspension, suitable for anion and cation systems, alkali resistance, defoaming, long foam suppression, wide application, good defoaming and foam suppression effects. 

This product overcomes the common organic silicon defoamers that are prone to oil floating, demulsification, and floating under high temperatures and alkaline conditions. The gypsum defoamer is particularly suitable for defoaming and foam suppression under alkaline conditions, high-temperature resistance, strong alkali resistance, and strong stability.

What is the principle of gypsum defoaming agent?


The principle of gypsum defoamer is to reduce the surface tension of gypsum slurry, making it easier for bubbles to burst and be eliminated. The active ingredients in the defoaming agent can be adsorbed on the surface of the bubbles, reducing the surface tension and reducing the viscosity of the gypsum slurry, making it easier for the bubbles to merge and be eliminated.


What types of gypsum defoamer are there?


There are many different types of gypsum defoamer, including mineral oil, silicone, polyether, etc. Different types of defoaming agents have different chemical compositions and performance characteristics, and the appropriate type should be selected according to needs.


How to use gypsum defoamer?


When using gypsum defoamer, the defoamer should be added to the gypsum slurry in the proportion required by the instructions and stirred thoroughly. Before use, shake evenly to avoid sedimentation. After use, it should be sealed and stored away from direct sunlight and humid environment.


How to choose a suitable gypsum defoamer?


When choosing a suitable gypsum defoamer, you need to consider the following aspects: first, choose a suitable defoamer according to the type and purpose of gypsum that needs to eliminate bubbles; second, choose a product with reliable quality and good brand reputation; finally, according to Follow the recommended proportions and usage instructions in the instruction manual.


What are the precautions for using gypsum defoamer?


When using gypsum defoamer, you should pay attention to the following points: first, choose the appropriate type and amount of defoamer; second, avoid mixing it with water or other solvents; finally, store it in a cool and dry place to avoid Direct sunlight and humid environment.
