Once titanium dioxide slurry enters the bead mill, high shear makes pigment particles re-flocculate; fineness readings rebound repeatedly near the acceptance line, the slurry coarsens at the tank bottom after standing, hiding power and whiteness fall batch by batch, and both let-down and filling pace are dragged down together.
Chemi Tech launches the KMK-201 series dispersant for inorganic-pigment and titanium-dioxide dispersion systems, with the addition level set flexibly against slurry solids and grinding intensity. This grade is a water-based dispersant whose anchoring groups grip the pigment surface and do not detach under high-shear grinding, achieving viscosity reduction and higher hiding power at the same time. Based on measured slurry-fineness and storage-stability data, the suitable dosage of the KMK-201 series can be determined.
Chemi Tech Dispersant Advantages
The Chemi Tech KMK-201 series dispersant is formulated for titanium-dioxide and inorganic-pigment systems. Anchoring is firm — pigment particles do not re-flocculate under high-shear grinding and the fineness-reduction process stays stable; viscosity reduction is significant, with grinding current leveling off once slurry flow improves; dispersion stability is outstanding — the slurry does not coarsen or settle during storage and hiding power stays stable; it adapts broadly to titanium dioxide and inorganic pigments, needing no frequent adjustment after batch changes; the dosage is economical, flexibly set against slurry solids, so the slurry meets spec in a single grind.
Industry Pain Points and Solutions
Dispersion problems in titanium dioxide slurry mostly share one root cause: high pigment surface energy and insufficient grinding shear acting together, ending up in two places — fineness rebound and storage re-coarsening.
Repeated fineness rebound slows the grinding pace and the batch-to-batch stability of the slurry falls. The KMK-201 dosage set against grinding intensity drives fineness down to the target in a single pass.
Storage re-coarsening hardens the slurry at the tank bottom after standing, and hiding power drifts during tinting. KMK-201's stable anchoring keeps the slurry from re-coarsening during storage.
Rework in grinding and tinting all lands on equipment occupancy and material loss. Against changes in slurry solids and grinding intensity, the dosage range can be set to keep the slurry stable and free of re-coarsening during storage.
Typical Conditions and Verification
Customer: a titanium-products enterprise in Sichuan, applied to the bead-milling section of its titanium dioxide slurry.
After this titanium-dioxide plant switched to a high-hiding-power grade, slurry fineness rebounded frequently and the tank bottom hardened from re-coarsening after two days of standing. The adaptation key became clear: use KMK-201 as the dispersant for the titanium dioxide slurry, with dosage set against slurry solids and grinding intensity kept in the normal range. Thereafter, fineness readings fell into the target range in one pass; standing storage no longer re-coarsened; hiding power and whiteness stayed stable, and downstream tinting complaints fell.
FAQ
After raising solids in titanium dioxide slurry, does the dispersant dosage need to be adjusted accordingly?
Hiding power in titanium dioxide slurry has always been limited by how thoroughly the pigment is dispersed. Higher solids raise the amount of anchoring groups needed, with the exact margin set against slurry solids and grinding intensity as the baseline. KMK-201 has completed grinding and storage comparison tests across multiple titanium-dioxide grades, with stable fineness within the recommended range; Chemi Tech determines the suitable dosage from the side-by-side comparison of slurry fineness and storage stability.
