Abstract
The present invention provides a kind of pipe fitting derusting method, comprises the following steps：A, remove slag, the outer surface of sand paper polishing pipe fitting, removes rust staining；B, clean, workpiece is rinsed with the giant of 5 10MPa；C, when immersion derusting oil 12 is small；D, neutralisation treatment, the workpiece after immersion derusting oil is added in alkaline solution and is neutralized；E, clean, cleaned 20 30 minutes with 50 70 DEG C of warm water；F, dry, dried workpiece with dryer.Pipe fitting derusting method of the present invention, process are simple and convenient to operate, can quick derusting, oxide covering is produced while derusting and reaches preferable rust-proof effect.
Description
Technical field
The present invention relates to a kind of metal surface rust-proofing method, more particularly to a kind of pipe fitting derusting method.
Background technology
Pipe fitting is hydraulic pressure term, is connecting line or the part by pipeline on Hydraulic Elements in hydraulic system, this
It is a kind of general name for the connector that can be assembled and disassembled in fluid passage.Pipe fitting is connected by being internally threaded, pipe fitting
Outer surface get rusty easily, it is necessary to carry out processing of rust removing to the pipe fitting that gets rusty, derusting method process at this stage is complex,
And easily get rusty again after derusting.
The content of the invention
【1】Technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of process is simple, derusting while produce oxide covering reach compared with
The pipe fitting derusting method of good rust-proof effect.
【2】The technical solution solved the problems, such as
A kind of pipe fitting derusting method, it is characterised in that comprise the following steps：
A, remove slag, the outer surface of sand paper polishing pipe fitting, removes rust staining；
B, clean, workpiece is rinsed with the giant of 5-10MPa；
C, when immersion derusting oil 1-2 is small；
D, neutralisation treatment, the workpiece after immersion derusting oil is added in alkaline solution and is neutralized；
E, clean, cleaned 20-30 minutes with 50-70 DEG C of warm water；
F, dry, dried workpiece with dryer.
Further, in step c, the constituent of the derusting oil is：Petroleum sodium sulfonate 4-7g/L, calcium mahogany sulfonate
6-10g/L, zinc oxide 18-22g/L, sulfuric acid 12-15ml/L, hydrochloric acid 18-25ml/L, hydrogen peroxide 30-35mL/L, remaining is water,
The oily operating temperature of derusting is 40-60 DEG C.
【3】Beneficial effect
Pipe fitting derusting method of the present invention, process are simple and convenient to operate, can quick derusting, derusting while produces oxygen
Change coating and reach preferable rust-proof effect.
Embodiment
The embodiment of the present invention is described in detail below.
A kind of pipe fitting derusting method, it is characterised in that comprise the following steps：
A, remove slag, the outer surface of sand paper polishing pipe fitting, removes rust staining；

D, neutralisation treatment, the workpiece after immersion derusting oil is added in alkaline solution and is neutralized；
E, clean, cleaned 20-30 minutes with 50-70 DEG C of warm water；
F, dry, dried workpiece with dryer.
In the present embodiment, in step c, the constituent for the oil that derusts is：Petroleum sodium sulfonate 4-7g/L, calcium mahogany sulfonate 6-
10g/L, zinc oxide 18-22g/L, sulfuric acid 12-15ml/L, hydrochloric acid 18-25ml/L, hydrogen peroxide 30-35mL/L, remaining is water, is removed
The oily operating temperature of rust is 40-60 DEG C.
Pipe fitting derusting method of the present invention, process are simple and convenient to operate, can quick derusting, derusting while produces oxygen
Change coating and reach preferable rust-proof effect.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
