摘要：

Zinc phosphate is a crystalline conversion coating that is formed on a metal substrate utilizing the chemical reaction between metal ions that have been dissolved in mineral acids and then diluted with water to form the process solution. Metals, such as zinc, nickel, and manganese, are dissolved depending on the process necessary. Several other metals can be dissolved to create specific characteristics. Accelerators are added to phosphating processes for specific reasons such as reaction speed, hydrogen elimination, and sludge formation control. Accelerators can be used as single materials or they can be mixed to achieve the most effective combination. The principal material to which zinc phosphate is applied is steel as well as, in varying proportions according to the particular part, precoating steel and aluminum. Galvanneal is a substrate that is produced by heat treating the hot-dipped, zinccoated steel sheet.
