In building construction, because cement mortar usually needs to add some additives, it is easy to cause foam in the cement mortar system during the mixing process. This kind of foam needs to be eliminated and suppressed. Otherwise, the firmness of the construction construction will not be worth the loss. Adding defoamer is a simple and direct method to eliminate foaming, and the dosage is small and the effect is obvious.

The hazards of cement mortar foaming
Foaming of cement mortar is also a common problem. Foam can easily lead to rough surface of components, cracks, hollow interior, channeling holes, overall looseness or obvious difference between upper and lower compressive strength and low overall compressive strength. Affect the tightness and firmness of the entire component, resulting in poor construction effect.
1. Foam will cause air in the cement mortar product to affect the firmness of the product;
2. Foam will affect the dispersion, plasticization and flow properties of cement mortar products;
3. Foam will affect the appearance and strength of cement mortar products. The surface is honeycomb-like, and the strength is not up to standard;
4. Foam will cause the quality of cement mortar products to decline and affect the fireproof, moisture-proof, anti-corrosion, heat-resistant, and cold-resistant properties.
Compound defoamer-good economy
In order to prevent the hazard of the foam of the cement mortar system, the foam can be controlled by adding a defoamer. Antifoaming agent is a chemical method of defoaming.

The cement mortar defoamer sold by Nanhui defoamer is highly targeted and has many formulas. The manufacturer has strong research and development capabilities and can be configured according to the customer's use environment, samples and requirements for defoamers. Therefore, Nanhui cement mortar defoamer It has the characteristics of low dosage, fast defoaming, and strong anti-foaming properties. Customer feedback is good.
When the defoamer is added to the foaming cement mortar system, the foam in the system can be extruded. It can quickly control the generation of foam in the cement mortar system, make the concrete components more dense and bright, the foam is eliminated, and a series of negative effects brought by the foam are naturally broken.
Features of Nanhui cement mortar defoamer
1. For compounding, the defoaming is well targeted, and the defoaming is obvious;
2. High concentration, small dosage, can be diluted and used, economical, and cost-effective;
3. It has good defoaming stability, will not react with the components in the cement mortar system, and will not affect the quality of cement products.
