Application of environmentally friendly dispersants in the ceramics industry

Introduction

Environmental dispersants are used in the ceramic industry to replace traditional, potentially harmful dispersants, in order to improve slurry stability, enhance body strength, and simplify processing. Their main applications include slip casting and the production of advanced ceramics and composite materials. Driven by stricter environmental regulations and the demand for more sustainable production, natural polymers such as water-based polymers are replacing synthetic alternatives.

Applications and Advantages of Ceramic Sanitary Ware in Production:

Grout preparation and casting

Glaze and underglaze formulation

Spray drying and powder processing

Environmental and cost advantages

In high-pressure or traditional grouting forming processes, the slurry must maintain fluidity, uniformity, and stability for a long time.

Evenly distributed glaze ensures a smooth surface and stable color after firing.

The stable dispersion during the atomization process of the slurry ensures uniform particle size, thereby improving the flowability and compressive density of the powder.
This ensures consistent green strength and dimensional accuracy during the forming process.

Compared to traditional sodium silicate or sodium tripolyphosphate, water-based polymers:

• No phosphorus pollution, no efflorescence;

• Reduce water consumption and drying energy consumption;

• Even with a low addition amount, they can significantly improve dispersion performance.

Aqueous polymer dispersant:

Reduces slurry viscosity, increasing solid content to 75-80%.
Improves particle dispersion, preventing sedimentation and mold clogging.
Increases slurry injection speed and enhances forming accuracy.

Polymer dispersants help to:

prevent glaze flocculation;
improve glaze adhesion and uniformity;
reduce defects such as pinholes and glaze flow.

Water-based polymer dispersants play a crucial role in modern sanitary ware production. By improving particle dispersion, enhancing fluidity, and reducing energy consumption, they can help manufacturers produce high-quality, defect-free, and environmentally friendly ceramics. For manufacturers aiming to optimize cost and performance, adopting advanced polymer dispersants is no longer optional but essential for the future.
