Kaolin dispersants SHMP and STPP: liberate iron so magnetic separators raise whiteness. 25 kg bags, Made in China.

Chemical Products

Answer first: PTMS Chemical Products include Sodium Hexametaphosphate (SHMP / 六偏磷酸钠) and Sodium Tripolyphosphate (STPP / 三聚磷酸钠) — kaolin dispersants (deflocculants). Both help liberate and disperse iron in kaolin and ceramic slurry/glaze so a magnetic separator can capture iron more effectively, achieving higher whiteness. SHMP bag: P₂O₅ 68% MIN, 25 kg; COA GH20260622 (HG/T2519-2017) P₂O₅ 68.1% / Fe 0.04% Qualified. STPP: Na₅P₃O₁₀, 25 kg; example COA STPP 93.9% / P₂O₅ 58.4% (GB/T9983-2004). Type I STPP: higher Type I → higher temperature rise on dissolving. Supplied by FOSHAN POWTECH TECHNOLOGY COMPANY LIMITED (PTMS). Quotation by inquiry — no public price. See dedicated SHMP and STPP product pages for full Q&A.

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.

Is there a public price?
