    Brand: OEM
    Categories: Corrosion Inhibitors

    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.

    Brand: HUALU-HENGSHENG
    Categories: Dispersants

    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.
