§ Plant Toolkit

Four calculators every plant chemist should bookmark.

First-order working estimates. The constants come from public literature and from the regression lines we fit during three decades of NGL line trials. Always verify against your own TDS and a controlled line trial before changing production.

01 · Retarder dose vs water hardness

NG-R 110 keratin or NG-R 220 citrate. First-order estimate; verify by Vicat.

02 · Foam draw vs target board density

Assumes ~93% stucco in core; adjust for high-fiber Type X.

04 · Dispersant dose vs W/S ratio

NG-D

Estimated dose

0.259 % bwoc

Verify by mini-cone flow at your slurry temperature.

Kiln gas saving

12.9 % vs neat

Indicative; couples to kiln zone re-tune.

Pair the suggested dose with NG-A 310 accelerator to compensate the PCE-extended induction period.

Disclaimer: outputs are indicative engineering estimates derived from public correlations and NGL internal regressions. They are not a substitute for line trials, current TDS, or on-site QC.
