Abstract
A kind of steel surface phosphating process.The present invention is carried out according to following processing step：1）Steel surface is carried out polishing, processing of rust removing.2）Steel are carried out pickling, carry out surface adjustment after alkali cleaning.3）By Phosphating Solution sediment, clear up and filter, it is 1 that adjustment Phosphating Solution makes the ratio of its free acidity and total acidity：（15-20）, described Phosphating Solution includes the following raw material with water as solvent：30% phosphoric acid, 10% nitric acid, 15% zinc oxide, 5% manganese salt, 8% nickel salt.4）Heating Phosphating Solution, makes temperature reach 30 degrees Celsius.5）The steel handled well are put into and in Phosphating Solution, carries out phosphatization, phosphating time 20 minutes.6）By washing, the Phosphating Solution of steel surface is removed, be dried after taking-up.Present invention process step is simple, and it is easy to operate, phosphating coat film forming speed is fast, and in the course of processing, the energy and Phosphating Solution consumption are less, high in machining efficiency.
Description
Technical field
The present invention relates to a kind of phosphorization treatment process, specifically a kind of steel surface phosphating process.
Background technology
Phosphatization is the process that a kind of chemistry and electrochemical reaction form phosphate chemical conversion film, and the phosphate conversion film being formed is referred to as phosphating coat.Phosphatization has good absorbability, preferable resistance to corrosion, and volume ratio is widely used in protection, japanning bottom of steel-iron components etc..
The energy that presently used alramenting technique is consumed and Phosphating Solution are more, and phosphating coat film forming speed is slow, and phosphatization speed is slower, and the low production efficiency of impact enterprise and economic benefit are it is therefore desirable to a kind of new technique solves the above problems.
Content of the invention
It is an object of the invention to, provide a kind of steel surface phosphating process, to improve phosphating coat film forming speed, improve production efficiency.
The technical scheme is that：Carry out steel surface bonderizing in following processing steps：
1）Steel surface is carried out polishing, processing of rust removing；
2）Steel are carried out pickling, carry out surface adjustment after alkali cleaning；
3）By Phosphating Solution sediment, clear up and filter, it is 1 that adjustment Phosphating Solution makes the ratio of its free acidity and total acidity：（15-20）, described Phosphating Solution includes the following raw material with water as solvent：30% phosphoric acid, 10% nitric acid, 15% zinc oxide, 5% manganese salt, 8% nickel salt；
4）Heating Phosphating Solution, makes temperature reach 25-35 degree Celsius；
5）The steel handled well are put into and in Phosphating Solution, carries out phosphatization, phosphating time is 15-25 minute；
6）By washing, the Phosphating Solution of steel surface is removed, be dried after taking-up.
The invention has the beneficial effects as follows, the steel surface phosphating process of patent of the present invention, step is simple, easily operated, and phosphating coat film forming speed is fast, and in the course of processing, the energy and Phosphating Solution consumption are less, high in machining efficiency.
Specific embodiment
The present invention is carried out according to following processing step：
1）Steel surface is carried out polishing, processing of rust removing；
2）Steel are carried out pickling, carry out surface adjustment after alkali cleaning；
3）By Phosphating Solution sediment, clear up and filter, it is 1 that adjustment Phosphating Solution makes the ratio of its free acidity and total acidity：（15-20）, described Phosphating Solution includes the following raw material with water as solvent：30% phosphoric acid, 10% nitric acid, 15% zinc oxide, 5% manganese salt, 8% nickel salt；
4）Heating Phosphating Solution, makes temperature reach 30 degrees Celsius；
5）The steel handled well are put into and in Phosphating Solution, carries out phosphatization, phosphating time 20 minutes；
6）By washing, the Phosphating Solution of steel surface is removed, be dried after taking-up.
Present invention process step is simple, and it is easy to operate, phosphating coat film forming speed is fast, and in the course of processing, the energy and Phosphating Solution consumption are less, high in machining efficiency.
It should be noted that, above example is only in order to illustrate technical scheme and unrestricted, although being described in detail to the present invention with reference to above-described embodiment, still technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention, all should cover in the middle of scope of the presently claimed invention.
