Iron oxide Silver powder, the of points is 53.62. It is difficult to combines with water. But can and acid type solvent unifies in together. It is two kinds of properties of steel oxidation product. The types of oxide, he used as a also different. The result is bad oxide physical surface contains many sundry, may lead to etch layer has a transparent phosphating film in water treatment, after lead to big yellow. Do phosphating solution when had better choose effect high oxide (purity or less than ninety-nine percent, direct production out). The purity of iron phosphating hydraulic according to different re, to choose a different oxide. Make the other component does not change, change the oxidation five purity, can improve the of the phosphating liquid. Improve the 2 g oxidation material can reduce the phosphating solution acidity, which in turn would increase a lot. Phosphating solution to add new ion the phosphating film become delicate, than manganese ion is much better. Acid agent Sulfuric acid score is 103.55, the density of 1.475. The use of sulfuric acid because it contains a certain amount of sundry display light yellow, strong corrosion resistance and water absorption performance. Mixed with water rapid response, and at the same time release a lot of heat. And the ratio of water after the sulfuric acid should be slowly down the hydraulic and colleagues constantly stir evenly. Can and a lot of metal, metal antioxidant reaction get salt composition. Sulfuric acid to phosphate coating and phosphate layer has the following influence Phosphate fluid in micro a small amount of sulfuric acid, in a sort of sense can increase the phosphate layer thickness and corrosion performance, the main reason is the reaction of sulfuric acid can improve phosphating of speed.

客户须知： 1.优良的磷化液必须要具备以下特性： ①工艺参数的范围要大，操作性能优良 ②配制成本较高，质量可靠性强 ③可用于批量生产，可调节性能好 ④符合环保规范 2.在此值得注意的是常温磷化液虽然节能，但磷化膜的质量与高温和中温相比要差的很多 3.且常温磷化液只能适用于批量不大的间歇式生产。 4.另一个是磷化液价格的问题，使用者都希望有志低廉的磷化液，但市场上销售的磷化液千差万别，选用时需加以区别。 5．除了要区别清楚各种磷化液的只用性能以外，还要兼顾磷化液的质量。 6．不要一味的追求价格便宜，很有可能出现质量的问题。 7.一旦选用了不合格的磷化液，会可能出现严重的质量问题。返工率增高的后果，不但省不了钱，反而增加了成本，甚至会出现客户丢失，令人深思。 8，还要合理掌握磷化质量的控制。实际使用中往往遇到厂家一些不切实际的要求，比如，提出过高的磷化膜要求。 9正确选用磷化液的方法一工件材质，质量要求，生产条件，工艺路线为依据。
