  • HPMA is a low molecular weight polymeride, with an average molecular weight of 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃.

  • PBTCA has a low phosphoric content and has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

  • HEDP is an organophosphorus acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals’ surfaces.

  • DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability.

  • ATMP has excellent chelation, low threshold inhibition, and lattice distortion ability. It can prevent scale formation, calcium carbonate, in particular, in the water system. ATMP has good chemical stability and is hard to be hydrolyzed in a water system.

  • Polyamine is liquid cationic polymers of different molecular weight which work efficiently as primary coagulants and charge neutralization agents in liquid-solid separation processes in a wide variety of industries.
