Cementing Additives

Oilwell Cementing Defoamers

The entrained air in the cement slurry during the mixing process can lead to a series of serious issues: deterioration in slurry performance, compromised cement job quality, and impaired cement stone strength. YouzhuCHEM provide Defoamer UBCem-541 to remove entrained air in the cement slurry, to enhance mixing effectiveness and improve slurry quality.

Type A polyether defoamer
Appearance Colorless to grey white liquid
Solubility Disperse in the water

Product introduction

▶UBCem-541 a polyether defoamer for use in asbestos production processing applications. It will prevent foaming in virtually any industrial application.

▶It acts quickly breaking up the foam without altering the effectiveness of the cleaning solution or effluent treatment chemicals being used.

UBCem-541 Defoamer Main Function in Cementing Operations:
The primary role of the UBCem-541 defoamer in cementing operations is to prevent and eliminate harmful foam within the cement slurry system. This ensures stable slurry properties, thereby guaranteeing the quality and safety of the cementing job.
● Maintaining Slurry Density
● Ensuring Slurry Rheology
● Improving Displacement Efficiency
● Ensuring Uniform Cement Strength

Applications/Functions

▶ High temperature, alkali and acid resistance.

▶ Compatibility with cement: suitable almost any type of foam.

▶ Easy to disperse in the water.

▶ Normal dosage: 10 to 100ppm, the best amount of addition by the customer according to the specific situation of the test decision.

Advantages

▶ Minimizes environmental impact

▶ Enhances mixing effectiveness

▶ Improves slurry quality and rheologic properties

▶ Elimination of chemical antifoaming fluids

Recommended Handling

▶ All personnel handling this material must handle it as an industrial chemical, wearing protective equipment and observing the precautions as described in the Material Safety Data Sheet (MSDS).
