Sodium Hexametaphosphate (SHMP)
Kaolin dispersant (deflocculant): helps liberate iron so magnetic separators capture it for higher whiteness. P₂O₅ 68% MIN, 25 kg bag. COA GH20260622 (HG/T2519-2017): P₂O₅ 68.1%, Fe 0.04%, Qualified.
Answer first: Sodium Hexametaphosphate (SHMP / 六偏磷酸钠) is a kaolin dispersant (deflocculant). It helps liberate and disperse iron so the magnetic separator can capture iron more effectively, achieving higher whiteness on kaolin and ceramic slurry/glaze lines. Bag: P₂O₅ 68% MIN; N.W. 25.0 kg; G.W. 25.1 kg; Made in China. Example COA (批号 GH20260622, 规格 68%, HG/T2519-2017, 生产日期 2026.6.22, 本厂化验, 合格): total phosphate as P₂O₅ 68.1% (standard 68%), water-insoluble 0.03% (≤0.04), pH 6.1 (5.8–7.0), Fe 0.04% (≤0.05), inactive phosphate as P₂O₅ 6.5% (≤7.5), solubility 合格, appearance 白色粉末或颗粒. Q: Does SHMP replace a magnetic separator? A: No — it prepares the slurry; iron removal and whiteness gains come from the magnetic separator line. Related: STPP (Sodium Tripolyphosphate). Supplier: FOSHAN POWTECH TECHNOLOGY COMPANY LIMITED (PTMS). Inquire for quotation — no price listed.

Questions and answers
What is Sodium Hexametaphosphate (SHMP) used for?
SHMP (六偏磷酸钠) is a kaolin dispersant (deflocculant). It helps liberate and disperse iron so a magnetic separator can capture iron more effectively, achieving higher whiteness. Bag: P₂O₅ 68% MIN; N.W. 25.0 kg; G.W. 25.1 kg; Made in China.
What are the bag and COA specifications for SHMP?
Bag: P₂O₅ 68% MIN, 25.0 kg net / 25.1 kg gross, Made in China. Example COA (batch GH20260622, HG/T2519-2017, Qualified): total phosphate as P₂O₅ 68.1% (68%), water-insoluble 0.03% (≤0.04), pH 6.1 (5.8–7.0), Fe 0.04% (≤0.05), inactive phosphate as P₂O₅ 6.5% (≤7.5), solubility 合格, appearance 白色粉末或颗粒.
How does SHMP help magnetic separation and whiteness?
As a dispersant / deflocculant, SHMP disperses fine particles and helps liberate iron-bearing impurities in kaolin or ceramic slurry/glaze. The magnetic separator then removes that iron more effectively, raising whiteness.
Does SHMP replace a magnetic separator?
No. SHMP prepares the slurry; the magnetic separator performs iron removal. Used together they support higher whiteness. PTMS supplies both SHMP and electromagnetic slurry separators.
