Protection of petroleum equipments by blending of friendly environmental resins and pigments

N.O.Shaker, R.Mansour, O.M.Abo-Elenien

Protection of petroleumequipments fromcorrosion is carried out by painting using a polycarbohydrate naturally occurring compound, chitosan. The paint materials are prepared by blending of environmental resin with inorganic pigments. The chitosan and polyethyleneglycol-polydimethy siloxane are prepared, purified and confirmed by FT-IR. The commercial novolac and epoxy resins are used. These resins are blended with each other at definite ratios. The inorganic pigments TiO2, Zn dust, Al2O3 and silica are also used at definite ratios. These materials are blended with each other to formdifferent formulaeA1-A12. Toluene diisocyanate is used as a curing agent. These formulae are applied on the carbon steel alloy specimens and are approved at Suez Oil Company. The physicalmechanical and chemical properties are investigated and recorded. The obtained data are performed for the formulaA4-A10 to protect the petroleum equipments.
