          HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃. HPMA has obvious threshold effect under high temperature (350℃) and high pH(8.3)level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300℃ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement

          Categories: Dispersants

          AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid. Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AA/AMPS has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale. When built with organophosphines, the synergic effect is obvious. AA/AMPS is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitor and dispersant on high concentration index.

          It is non-flammable and has stable property in normal temperature. Its water solution is slightly alkaline , and can react with hydrochloric acid, sulfuric acid, nitric acid, acetic acid and oxalic acid etc. to form melamine. In neutral or slightly alkaline state, it can be synthesized with formaldehyde to form various methylol melamines, but in subacidity (pH value 5.5-6.5), it can have polycondensation with the methylol derivatives to generate resin products. In case of strong acid or strong alkaline water solution, it can be hydrolyzed, the amino group is generally replaced by hydroxyl group to first ammeline first, and then it is further hydrolyzed to generate ammelide, and finally generate cyanuric acid.
