Properties
The polymer body contains strong cationic group radical and activated-adsorbent group radical which can destabilize and flocculate the suspended solids and the negative-charged water soluble matters in the waste water through electro-neutralization and bridging adsorption. It is very effective in flocculating, decolouring, killing algae and removing organics. The product enjoys small dosage but can cause big flocs, rapid precipitation and low turbidity residue, and it can also produce small amount of sludge. It is adaptable to wide range of pH value, between 0.5 and 1.4. This product is smelless, tasteless and harmless. It can be widely used to treat source water and sewage water.

Functional principle
Flocculation Mechanism: Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging, and make flocculation structure enlarge and thicken, and has the functions of surface adsorption and electric neutralization. Reinforcing Mechanism: PAM molecule chain and dispersed phase form bridging bond, ion bond and covalent bond to increase combination strength.
Application introduction
PAM series products contain affinity radical and they can dissolve in water easily and play the role of flocculation, filtering-assist, increasing adherence, reducing resistance, coherence, reinforcing and rheologic regulation and can be used extensively. Flocculation property can be used for recovering solid substance, treating various industrial sewage, domestic sewage and purifying water, assisting filtering, treatment of tail coal as well as well-drilling slurry material etc. With the rheologic regulation function PAM can thicken water recover driving agent for oil field to reform ground section, enhance adoption ratio. It can make up fracturing solution to fracture the stratum which is difficult to drill and it also can make up well-drilling solution which can reduce friction and resistance, accelerate drilling speed, improve drilling depth. With the property of adherence and reinforcing of PAM, it can be used for paper-making industry to enhance staying rate of filling material, speed size filterability and white water sediment in the paper and then coagulate to increase the strength of the paper. PAM can be used with polyvinyl alcohol as textile size, this can improve textile process and enhance the property of textile.

Properties
HEDP is an organophosphoric 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 metalsí» surfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250íµ. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
The solid state of HEDP is crystal powder, suitable for Usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.
Usage:
HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.
