Abstract
The invention relates to steel phosphorization treating fluid belonging to the field of chemistry. The steel phosphorization treating fluid comprises the following components in parts by weight: 100-120 parts of Zn (NO2)2.6H2O, 25-35 parts of manganese dihydrogen phosphate, 2-6 parts of NaNO2, 0.5-3.5 parts of accelerating agent C, 4-10 parts of free acid/point and 55-75 parts of total acidity/point. The invention is a phosphorization fluid formula of a phosphorization film, which has simple and reasonable formula, is suitable for automobile industry, ship industry, mechanical industry, weapon industry and space flight and aviation industry, can prevent a part from being bonded with a mould in part pressure casting, has a micropore structure, can form a film rapidly after being filled, immersed in oil or painted and has better corrosion resistance and extremely good surface condition.
Description
Technical field
The present invention relates to a kind of steel iron phosphatising treatment solution, belong to chemical field.
Background technology
Phosphatization is the process that a kind of chemistry and electrochemical reaction form the phosphate chemical conversion film, and formed phosphate conversion film is referred to as phosphatize phosphate coat.The purpose of phosphatization mainly is: provide protection to matrix metal, prevent that to a certain extent metal is corroded; The preceding bottoming that is used to paint improves the sticking power and the anti-corrosion capability of paint film layer; Play in the metal cold machining process that antifriction is lubricated to be used, but phosphatization commonly used now also when part die casting appears in regular meeting part and mould defective such as cohere.
Summary of the invention
The purpose of this invention is to provide a kind of automobile, boats and ships, machinery, weapons and space flight, aircraft industry of being applicable to, the cohering of part and mould when can be used to prevent part die casting has the steel iron phosphatising treatment solution of corrosion stability preferably.
In order to realize above purpose, technical scheme of the present invention is:
The steel iron phosphatising treatment solution is characterized in that the ratio of weight and number of contained each composition is: Zn (NO
