BACKGROUND: A review of the literature showed that the core competencies needed by newly graduated Chinese nurses were not as of yet undocumented. OBJECTIVE: To develop a psychometrically sound instrument for identifying and measuring the core competencies needed by Chinese nursing baccalaureate graduates.
A&P here. Zinc chromate is used as a primer on aluminum surfaces as a conversion process to inhibit corrosion. Since nearly all modern aircraft skins and structures are made from aluminum, this compound and its derivatives are the most common primers seen in aircraft manufacturing.
Inorganic zinc-rich primers come in two parts; a small quantity of a clear silicate resin in one can, and a large volume of zinc powder in the other. The difficulty faced by the painter is to intimately mix the zinc with the silicate resin.hese primers can be applied over clean bare metal or over previously applied paint. As with all coating applications, surface preparation is critical, and you should read the instructions that come with the primer. In any case, conventional primers are more tolerant to the surface condition that is the zinc-rich.
