Process liquid for alramenting hardware

Abstract

This invention relates to a surface granosealing liquid for metal components with a specific proportion of raw materials as follows: 170 shares of phosphate acid, 0.4 share of sodium molybdate, 5 shares of potassium carbonate, 0.1 share of molybdenum carbonate, 0.25 share of 0ªð-10, 0.3 share of oxydol and 1000 shares of pure water. This invention has the advantages of: a) wide application. It is applicable in surface granosealing for all kinds of steel products and components with a broad temperature range. Typically it can be employed below 0 and thus can meet the needs from most places in winter. b) Energy economization. Granosealing can be carried out at room temperature so that energy would be saved. c) Rapid filming, uniform film density, strong adhesion and low probability of repetitive rusting.

Description

[0001] Field:

[0002] The invention belongs to a phosphating solution for performing phosphating treatment on the surface of metal components before coating. Background technique:

[0003] At present, the phosphating treatment on the surface of various steel products and components before coating requires heating the phosphating solution before phosphating. Therefore, the process is complicated and consumes energy. Invention content:

[0004] The object of the present invention is to overcome the shortcomings in the above-mentioned prior art, and provide an energy-saving normal-temperature rapid phosphating solution that can simplify the phosphating process.

[0005] The technical solution of the present invention is: a metal component surface phosphating treatment solution, characterized in that: it is made of the following raw materials according to the following weight ratio: 170 parts of phosphoric acid, sodium molybdate, 0.4 part of potassium carbonate, 5 parts of moly...
