A comparison study on corrosion behavior of zinc phosphate and potassium zinc phosphate anticorrosive pigments
In this article, the effect of potassium on structure and anticorrosion properties of zinc phosphate pigments has been investigated. The co-precipitation method was selected as synthesis method of potassium zinc phosphate pigment. Then the synthesized pigment was characterized by x-ray diffraction XRD, Fourier transform infrared FTIR and Raman spectroscopy. Morphology of the powders was investi...
متن کاملRecycling Zinc Phosphate Sludge
he cost of sludge disposal can contribute significantly to the cost of product manufacturing. An opportunity exists to eliminate this cost of land disposal of sludge resulting from the zinc phosphate pretreatment process. In addition, the cost of the phosphating process may be reduced by reclaiming this sludge to a zinc-phosphate replenishment solution and other useful products. For those not f...
متن کاملAN IMPROVEMENT TO THE ANTICORROSIVE PROPERTIES OF EPOXY POWDER COATING BY ZINC PHOSPHATE AND ZINC ALUMINUM PHOSPHATE PIGMENTS
Epoxy powder coatings containing zinc aluminum phosphate (ZAP) and zinc phosphate (ZP), which are the 2nd and 1st generation of phosphate-based pigments respectively, were applied to the surface of mild steel sheets. The anticorrosive performances of the coated samples were studied using electrochemical impedance spectroscopy (EIS). Cathodic disbonding resistance and the adhesion performance of...
متن کاملZinc and Zinc Compounds
Zinc is an essential element in people’s diet. Too little zinc can cause health problems, but too much zinc is harmful. The U.S. Recommended Dietary Allowance (U.S. RDA) for zinc is 5 15 milligrams a day for humans. Not enough zinc in one’s diet can result in a loss of appetite, a decreased sense of taste and smell, slow wound healing and skin sores, or a damaged immune system. Young men who do...
متن کاملSalivary zinc as an index of zinc status in women fed a low-zinc diet.
The effect of a low-zinc diet on saliva and plasma levels was studied in 12 healthy young women. A diet low in zinc (3.2 mg/day) was fed to the subjects for 22 days. Subjects were determined to be in satisfactory zinc status via analysis of the zinc levels of their diet, hair, plasma, and saliva. During the low-zinc diet, concentrations of zinc in whole mixed saliva remained relatively stable f...
