摘要： Equations have been developed to predict the amount of sludge formed during, and the values of several other characteristics of, zinc phosphating processes. Using these equations, novel compositions that achieve low sludge without sacrificing other characteristics of good zinc phosphate coatings have been discovered.

摘要： An aqueous solution of manganese phosphate and phosphoric acid, preferably with little or no content of any material conventionally recognized as an accelerator or of any divalent metal ions other than manganese and iron, forms a good quality paint undercoating phosphate conversion coating on metal substrates, particularly on steel and galvanized steel substrates, when contacted by spraying or immersion with the substrates at a temperature of 54.degree.-65.degree. C. for a time of 2-5 minutes.

摘要： The following water soluble materials are all satisfactory internal accelerators for otherwise conventional zinc phosphate conversion coating solutions: reducing sugars, starch, urea, and poly{acrylates and methacrylates}. Concentrates including these ingredients and otherwise conventional constituents of zinc phosphate conversion coating compositions, except for excluding conventional accelerators other than nitrate, are stable in composition during storage, unlike most conversion coating compositions containing conventional accelerators. Thus concentrates according to the invention are practical single-package concentrates that can be made into working phosphating compositions by dilution with water only.
摘要翻译： 以下水溶性材料都是令人满意的内部加速剂，用于其他常规的磷酸锌转化涂层溶液：还原糖，淀粉，尿素和聚{丙烯酸酯和甲基丙烯酸酯}。 除了不包括除硝酸盐以外的常规促进剂之外，包括这些成分和除磷酸锌转化涂料组合物的常规成分的浓缩物在储存期间的组成稳定，与含有常规促进剂的大多数转化涂料组合物不同。 因此，根据本发明的浓缩物是实际的单包装浓缩物，其可以仅通过用水稀释制成工作磷酸盐组合物。
