Summary of the invention
The object of the present invention is to provide a kind of environment-friendly type, stability and persistence are all higher, do not need the metal surface treating liquid of complex process operation simultaneously.
To achieve these goals, the invention provides following technical scheme:
A kind of environment-friendly multifunctional metallic face treatment solution, is made up of raw materials such as phosphoric acid, organic acid, tensio-active agent, catalyzer, reductive agent, inhibiter, purifying agents, and its concrete proportioning (%) is as follows:
The beneficial effect that the present invention brings is: the maximum feature of this treatment solution is to integrate oil removing, rust cleaning, phosphatization, passivation, can carry out with several different methods such as dipping, spray, brushings at normal temperatures, metallic surface is not needed to oil removing in advance, rust cleaning, cleaning, do not need to heat yet, therefore operation is very simple, and at process for preparation three-waste free discharge, is a kind of product of environment-friendly type, be used for the anticorrosion, antirust of metallic surface, effect is splendid.
Embodiment
The present invention is a kind of environment-friendly multifunctional metallic face treatment solution, is made up of raw materials such as phosphoric acid, organic acid, tensio-active agent, catalyzer, reductive agent, inhibiter, purifying agents, and its concrete proportioning (%) is:
Using method of the present invention and precaution:
One. pickling process
Pickling process is used generally carries out in workshop, and the container of depositing this liquid is required to be acidproof groove.
Step: a., for avoiding reducing tank liquor function, first removes serious grease, plaster and the alkaline foreign material of surface of workpiece.
B. metal works is immersed and is placed with in the groove pond of this liquid, descale, rusty scale, phosphatization, purifying comprehensive treating process.Tank liquor is processed and need to be flooded 20 to 30 minutes under low-temperature condition; Under normal temperature, process, need 5 to 15 minutes, in steeping process, preferably can make liquid-flow or vibration.
C. workpiece after treatment must uprightly be placed, and air seasoning, is generally 4 to 8 hours time of drying.
Precaution:
In use procedure, the workpiece quantity of dipping is many, the corresponding minimizing of solution and acidity, and dipping time also progressively increases, and this is to add new liquid, keeps certain acidity;
Tank liquor temperature is unsuitable too high;
Use after for some time, when throw out is more in groove, after can wire cloth filtering, re-use;
This liquid of per kilogram can be processed 6 millimeters of following metal works areas and be no less than 20 square metres, floods every square metre of metal works, consumes 60 to 60 grams of this liquid.
Two. spray (spilling) squeegee process
The method is usually used in the maintenance and repair aspect of outdoor metal workpiece.
Step: have the alkaline matters such as the grease of serious rust staining and lime, cement on a. metal works, must brush off or root out with iron, general corrosion be without processing.
B. spray, be painted on workpiece surface by this liquid stoste, direct coating finish after it is dry.Be 2 to 4 hours time of drying, 1 hour summer.
Precaution:
The coating finish of can not being eager before dry, in order to avoid reduce the sticking power of paint film and mother metal, affects coating quality.
Workpiece after treatment, can not contact wetting before coating finish not, prevents from destroying rete.Therefore coating finish that must be as early as possible in field operation, guarantees quality.
Workpiece after the comprehensive treating process of this liquid has following situations to occur, is allowable defect:
1. slight water mark, wiping bletilla dust phenomenon;
2. remove corrosion place inconsistent with overall color and luster.
This liquid is that stoste is used, and does not need to be in harmonious proportion.This liquid must support the use with finish paint, just can obtain preservative effect.It is rotten that this liquid is difficult for performance, and In Shade at normal temperatures, validity period is 2 years.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
