Ferrous sulfate, commonly known as green vitriol, is a sulfate of iron consisting of sky-blue or green monoclinic crystals or crystalline powder, with a relative density of 1.8987 and melting point of 64 °C; it is odorless and convergent and weathers when exposed to air, with the surface turning into a white powder; it is subject to oxidization in moist air, with a brown ferric subsulfate appearing on the surface; it is water glycerol soluble and insoluble in alcohol; ferrous sulfate is reductive and turns from a heptahydrate into a tetrahydrate at 56.6°C, and into a monohydrate at 64.6°C; it loses six crystal water molecules at 90°C, and all the crystal water molecules at 300°C, and decomposes to give off SO2 and SO3 in red hot state; it is also corrosive and fluoresces in dry air; its anhydride form is a white powder, which turns blue-green when reacting with water.

DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210℃) DTPMPA has better scale and corrosion inhibition effect than other organophosphines.
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

Polyacrylamide is a white powder or small particle substance.Chinese alias: flocculant, English name;PAM (acrylamide)
PAM is a kind of linear polymer, the products are mainly divided into dry powder and colloidal form.According to its average molecular weight, it can be divided into three types: low molecular weight (<1 million), medium molecular weight (2-4 million) and high molecular weight (>.7 million).According to its structure, it can be divided into four types: non-ionic type, anionic type, cation type and amphoteric type.
